According to the passage, some managers don't have to do any letter writing because _ .

Like fine food, good writing is something we approach with pleasure and enjoy from the first taste to the last. And good writers, good cooks, do not suddenly appear full-blown. Quite the contrary, just as the cook has to undergo an intensive training, mastering the skills of his trade, the writer must sit at his desk and devote long hours to achieving a style in his writing, whatever its purpose-schoolwork, matters of business, or purely social communication. You may be sure that the more painstaking the effort, the more effective the writing, and the more rewarding. There are still some remote places in the world where you might find a public scribe to do your business or social writing for you, for a fee. There are a few managers who are lucky enough to have the service of that rate kind of secretary who can take care of all sorts of letter writing with no more than a quick note to work from. But for most of us, if there is any writing to be done, we have to do it ourselves. We have to write school papers, business papers or home papers. We are constantly called on to put words to paper. It would be difficult to count the number of such words, messages, letters, and reports put into the mails or delivered by hand, but the daily figure must be enormous. What is more, everyone who writes expects, or at least hopes. We want whatever we write to be read, from first word to last, not just thrown into some "letters-to-be-read" file or into a wastepaper basket. This is the reason we bend our efforts toward learning and practicing the skill of interesting, effective writing.

The time needed in making decisions may____.

Scientists have found that although we are prone to snap overreactions, if we take a moment and think about how we are likely to react, we can reduce or even eliminate the negative effects of our quick, hard-wired responses. Snap decisions can be important defense mechanisms; if we are judging whether someone is dangerous, our brains and bodies are hard-wired to react very quickly, within milliseconds. But we need more time to assess other factors. To accurately tell whether someone is sociable, studies show, we need at least a minute, preferably five. It takes a while to judge complex aspects of perso nality, like neuroticism or open-mindedness. But snap decisions in reaction to rapid stimuli aren't exclusive to the interpersonal realm. Psychologists at the University of Toronto found that viewing a fast-food logo for just a few milliseconds primes us to read 20 percent faster, even though reading has little to do with eating. We unconsciously associate fast food with speed and impatience and carry those impulses into whatever else we're doing. Subjects exposed to fast-food flashes also tend to think a musical piece lasts too long. Yet we can reverse such influences. If we know we will overreact to consumer products or housing options when we see a happy face (one reason good sales representatives and real estate agents are always smiling), we can take a moment before buying. If we know female job screeners are more likely to reject attractive female applicants, we can help screeners understand their biases - or hire outside screeners. John Gottman, the marriage expert, explains that we quickly "thin slice" information reliably only after we ground such snap reactions in "thick sliced" long-term study. When Dr. Gottman really wants to assess whether a couple will stay together, he invites them to his island retreat for a much longer evaluation: two days, not two seconds. Our ability to mute our hard-wired reactions by pausing is what differentiates us from animals: dogs can think about the future only intermittently or for a few minutes. But historically we have spent about 12 percent of our days contemplating the longer term. Although technology might change the way we react, it hasn't changed our nature. We still have the imaginative capacity to rise above temptation and reverse the high-speed trend.

What does the passage mainly discuss?

Some animal behaviorists argue that certain animals can remember past events, anticipate future ones, make plans and choices, and coordinate activities within a group. These scientists, however, are cautious about the extent to which animals can be credited with conscious processing. Explanations of animal behavior that leave out any sort of consciousness at all and ascribe actions entirely to instinct leave many questions unanswered. One example of such unexplained behavior: honeybees communicate the sources of nectar to one another by doing a dance in a figure-eight pattern. The orientation of the dance conveys the position of the food relative to the sun's position in the sky, and the speed of the dance tells how far the food source is from the hive. Most researchers assume that the ability to perform and encode the dance is innate and shows no special intelligence. But in one study, when experimenters kept changing the site of the food source, each time moving the food 25 percent farther from the previous site, foraging honeybees began to anticipate where the food source would appear next. When the researchers arrived at the new location, they would find the bees circling the spot, waiting for their food. No one has yet explained how bees, whose brains weigh four ten-thousandths of an ounce, could have inferred the location of the new site. Other behaviors that may indicate some cognition include tool use. Many animals, like the otter who uses a stone to crack mussel shells, are capable of using objects in the natural environment as rudimentary tools. One researcher has found that mother chimpanzees occasionally show their young how to use tools to open hard nuts. In one study, chimpanzees compared two pairs of food wells containing chocolate chips. One pair might contain, say, five chips and three chips, the other four chips and three chips. Allowed to choose which pair they wanted, the chimpanzees almost always chose the one with the higher total, showing some sort of summing ability. Other chimpanzees have learned to use numerals to label quantities of items and do simple sums.

Scientists concluded from the experiment with chimpanzees and chocolate chips that chimpanzees

Some animal behaviorists argue that certain animals can remember past events, anticipate future ones, make plans and choices, and coordinate activities within a group. These scientists, however, are cautious about the extent to which animals can be credited with conscious processing. Explanations of animal behavior that leave out any sort of consciousness at all and ascribe actions entirely to instinct leave many questions unanswered. One example of such unexplained behavior: honeybees communicate the sources of nectar to one another by doing a dance in a figure-eight pattern. The orientation of the dance conveys the position of the food relative to the sun's position in the sky, and the speed of the dance tells how far the food source is from the hive. Most researchers assume that the ability to perform and encode the dance is innate and shows no special intelligence. But in one study, when experimenters kept changing the site of the food source, each time moving the food 25 percent farther from the previous site, foraging honeybees began to anticipate where the food source would appear next. When the researchers arrived at the new location, they would find the bees circling the spot, waiting for their food.

A main purpose of the passage is to

Whether the languages of the ancient American peoples were used for expressing abstract universal concepts can be clearly answered in the case of Nahuatl. Nahuatl, like Greek and German, is a language that allows the formation of extensive compounds. By the combination of radicals or semantic elements, single compound words can express complex conceptual relations, often of an abstract universal character. The tlamatinime ( "those who know" ) were able to use this rich stock of abstract terms to express the nuances of their thought. They also availed themselves of other forms of expression with metaphorical meaning, some probably original, some derived from Toltec coinages. Of these forms the most characteristic in Nahuatl is the juxtaposition of two words that, because they are synonyms, associated terms, or even contraries, complement each other to evoke one single idea.Used as metaphor, the juxtaposed terms connote specific or essential traits of the being they refer to, introducing a mode of poetry as an almost habitual form of expression.

The government stopped issuing or renewing permits for Internet cafes.

Three months after the government stopped issuingor renewing permits for Internet cafes because of securityconcerns, some cafe owners are having financialconcerns of their own. The permits were stopped suddenly three months ago by the government until new safeguards could be put in place to prevent misuse of the information superhighway, but for cafe owners it's a business breakdown with no fix in sight. "I handed in a request to open up an Internet café and received the conditions," said the businessman Obeidallah. "I rented a place in the Sharafiah district at SR45,000 and prepared the place with equipment that cost me more than SR100,000. When I went to the local government after finishing everything, I was surprised to find that they'd stopped issuing permits for Internet cafes." Having an Internet cafe without Internet is much like having a coffee shop without coffee. "I'm avoiding closing the place, but it's been more than three months with the situation ongoing as it is." Obeidallah said. "Who will bear the losses caused by the permit issue?" The decision took many cafe owners by surprise. "I asked to open an Internet café, and I was handed a list of all the things that were needed to follow through, such as a sign for the place, filling out forms," said Hassan Al-Harbi. "I did all that was asked and rented a place. And after the Haj vacation I went to the local government and they surprised me, saying that there are new rules that forbid the issuing of any more Internet cafe permits and that one can't even renew his permit. I've lost more than SR80,000," Al-harbi added. As for the government, officials say a method to deal with it is on the way. But security concerns come before profit.

Eagerly watching the child's acquisition of new skills _ .

In bringing up children, every parent watches eagerly the child's acquisition of each new skill-the first spoken words, the first independent steps, or the beginning of reading and writing. It is often tempting to hurry the child beyond his natural learning rate, but this can set up dangerous feelings of failure and states of worry in the child: This might happen at any stage. A baby might be forced to use a toilet too early, a young child might be encouraged to learn to read before he knows the meaning of the words he reads. On the other hand, though, if a child is left alone too much, or without any learning opportunities, he loses his natural enthusiasm for life and his desire to find out new things for himself. Patents vary greatly in their degree of strictness towards their children. Some may be especially strict in money matters. Others are sever over times of coming home at night or punctuality for meals. In general, the controls imposed represent the needs of the parents and the values of the community as much as the child's own happiness. As regards the development of moral standards in the growing child, consistency is very important in parental teaching. To forbid a thing one day and excuse it the next is no foundation for morality. Also, parents should realize that "example is better than precept". If they are not sincere and do not practise what they preach, their children may grow confused, and emotionally insecure when they grow old enough to think for themselves, and realize they have been to some extent fooled. A sudden awareness of a marked difference between their parents' principles and their morals can be a dangerous disappointment.

Even if you are a good high-jumper, you can jump only about seven feet off the ground. You cannot jump any higher because the earth pulls you hard. The pull of the earth is called gravity. You can easily find out the pull of the earth. If you weigh yourself, you will know how much gravity is pulling you. Since there is gravity, water runs down hill. When you throw a ball into the air, it falls back down. Because of gravity, you do not fall off the earth as it whirls around. Then, can we get away from the earth and go far out into space? Now you can do it, because spaceships have been invented. Then spaceship will go so fast that it can escape the earth's gravity and carry you into space.

What do we learn about the decision of technical and community colleges in Tennessee?

Tennessee's technical and community colleges will not outsource management of their facilities to a private company, a decision one leader said was bolstered by an analysis of spending at each campus. In an email sent Monday to college presidents in the Tennessee Board of Regents system, outgoing Chancellor John Morgan said an internal analysis showed that each campus' spending on facilities management fell well below the industry standards identified by the state. Morgan said those findings-which included data from the system's 13 community colleges, 27 technical colleges and six universities-were part of the decision not to move forward with Governor Bill Haslam's proposal to privatize management of state buildings in an effort to save money. "While these numbers are still being validated by the state, we feel any adjustments they might suggest will be immaterial," Morgan wrote to the presidents. "System institutions are operating very efficiently based on this analysis, raising the question of the value of pursuing a broad scale outsourcing initiative." Worker's advocates have criticized Haslam's plan, saying it would mean some campus workers would lose their jobs or benefits. Haslam has said colleges would be free to opt in or out of the out souring plan, which has not been finalized. Morgan notified the Haslam administration of his decision to opt out in a letter sent last week. That letter, which includes several concerns Morgan has with the plan, was originally obtained by The Commercial Appeal in Memphis. In an email statement from the state's Office of Customer Focused Government, which is examining the possibility of outsourcing, spokeswoman Michelle R. Martin said officials were still working to analyze the data from the Board of Regents. Data on management expenses at the college system and in other state departments will be part of a "business justification" the state will use as officials deliberate the specifics of an outsourcing plan. "The state's facilities management project team is still in the process of developing its business justification and expects to have that completed and available to the public at the end of February," Martin said. "At this time there is nothing to take action on since the analysis has yet to be completed." Morgan's comments on outsourcing mark the second time this month that he has come out against one of Haslam's plans for higher education in Tennessee. Morgan said last week that he would retire at the end of January because of the governor's proposal to split off six universities of the Board of Regents system and create separate governing boards for each of them. In his resignation letter, Morgan called the reorganization "unworkable".

Morgan's comments on outsourcing mark the second time this month that he has come out against one of Haslam's plans for higher education in Tennessee. Morgan said last week that he would retire at the end of January because of the governor's proposal to split off six universities of the Board of Regents system and create separate governing boards for each of them. In his resignation letter, Morgan called the reorganization "unworkable".

Claire Brickell, 25, an aspiring neurologist in her third year at Harvard Medical School, already knows far more about health care than most of us. She can diagnose heart failure from a chest X ray. She can diagram the intricate circuits of the brain. And if she needed to, she could probably pull off a pretty decent tracheotomy. But when it comes to communicating with patients, Brickell has a problem: she's too healthy. Like most of her classmates, she has spent very little time as a patient. She has never had to weigh the advice of a trusted friend against conflicting orders given by a cold and distant doctor. She has never had to take daily injections for a disease she doesn't understand. She has rarely even gone through the most basic crucible of illness in the U. S. , the interminable wait in a doctor's office. Enter Santa Ocasio, 56, a Dominican immigrant who is fighting a protracted battle with Type 2 diabetes. In a pilot program that is the leading edge of a broad curriculum overhaul at Harvard Medical School, Brickell has been paired with Ocasio for nearly five months. ~ She sees her as a patient every week at the Spanish Clinic of Boston's Brigham and Women's Hospital and tags along on visits to her specialists. In fact, the goal is for Brickell to be there every time Ocasio encounters the health-care system. It's not just a way to learn about treating diabetes; it's a crash course in the myriad frustrations of a patient caught in the maw of modern medicine--confusing prescriptions, language barriers and an endless parade of strangers in white coats. Why would the U. S. 's top medical school ask its students to spend valuable time trailing a patient instead of a doctor? At Harvard and other medical schools across the country, educators are beginning to realize that empathy is as valuable to a doctor as any clinical skill. Whether it' s acknowledging that a patient was inconvenienced by having to wait an hour before being seen or listening when someone explains why he didn't take his meds, doctors who try to understand their patients may be the best antidote for the widespread dissatisfaction with today's health-care system. So Harvard has built closer partnerships between students and patients into the principal clinical experience, a small but important part of its most significant curriculum reform in two decades. The University of Pennsylvania Medical School began a similar program in 1997, and other schools are following suit. As long as medical students are still getting a healthy diet of clinical learning, educators say, there's little downside. [435 words]

To the author, the auction of his great-grandfather is a typical example of ________.

In 1854 my great-grandfather, Morris Marable, was sold on an auction block in Georgia for $500. For his white slave master, the sale was just "business as usual." But to Morris Marable and his heirs, slavery was a crime against our humanity. This pattern of human rights violations against enslaved African-Americans continued under racial segregation for nearly another century. The fundamental problem of American democracy in the 21st century is the problem of "structural racism" the deep patterns of socio-economic inequality and accumulated disadvantage that are coded by race, and constantly justified in public speeches by both racist stereotypes and white indifference. Do Americans have the capacity and vision to remove these structural barriers that deny democratic rights and opportunities to millions of their fellow citizens? This country has previously witnessed two great struggles to achieve a truly multicultural democracy. The First Reconstruction (1865-1877) ended slavery and briefly gave black men voting rights, but gave no meaningful compensation for two centuries of unpaid labor. The promise of "40 acres and a mule "was for most blacks a dream deferred . The Second Reconstruction (1954-1968), or the modern civil rights movement, ended legal segregation in public accommodations and gave blacks voting rights. But these successes paradoxically obscure the tremendous human costs of historically accumulated disadvantage that remain central to black Americans' lives. The disproportionate wealth that most whites enjoy today was first constructed from centuries of unpaid black labor. Many white institutions, including some leading universities, insurance companies and banks, profited from slavery. This pattern of white privilege and black inequality continues today. Demanding reparations is not just about compensation for slavery and segregation. It is, more important, an educational campaign to highlight the contemporary reality of "racial deficits" of all kinds, the unequal conditions that impact blacks regardless of class. Structural racism's barriers include "equity inequity." the absence of black capital formation that is a direct consequence of America's history. One third of all black households actually have negative net wealth. In 1998 the typical black family's net wealth was $16,400, less than one fifth that of white families. Black families are denied home loans at twice the rate of whites. Blacks remain the last hired and first fired during recessions. During the 1990-91 recession, African-Americans suffered disproportionately. At Coca-Cola, 42 percent of employees who lost their jobs were blacks. At Sears, 54 percent were black, Blacks have significantly shorter life spans, in part due to racism in the health establishment. Blacks are statistically less likely than whites to be referred for kidney transplants or early-stage cancer surgery.

According to the first paragraph, the process of discovery is characterized by its

In the idealized version of how science is done, facts about the world are waiting to be observed and collected by objective researchers who use the scientific method to carry out their work. But in the everyday practice of science, discovery frequently follows an ambiguous and complicated route. We aim to be objective, but we cannot escape the context of our unique life experience. Prior knowledge and interest influence what we experience, what we think our experiences mean, and the subsequent actions we take. Opportunities for misinterpretation, error, and self-deception abound. Consequently, discovery claims should be thought of as protoscience. ②Similar to newly staked mining claims, they are full of potential. But it takes collective scrutiny and acceptance to transform a discovery claim into a mature discovery. This is the credibility process, through which the individual researcher's me, here, now becomes the community's anyone, anywhere, anytime. Objective knowledge is the goal, not the starting point. Once a discovery claim becomes public, the discoverer receives intellectual credit. But, unlike with mining claims, the community takes control of what happens next. Within the complex social structure of the scientific community, researchers make discoveries; editors and reviewers act as gatekeepers by controlling the publication process; other scientists use the new finding to suit their own purposes; and finally, the public (including other scientists) receives the new discovery and possibly accompanying technology. As a discovery claim works its way through the community, the interaction and confrontation between shared and competing beliefs about the science and the technology involved transforms an individual's discovery claim into the community's credible discovery. Two paradoxes exist throughout this credibility process. First, scientific work tends to focus on some aspect of prevailing Knowledge that is viewed as incomplete or incorrect. Little reward accompanies duplication and confirmation of what is already known and believed. The goal is new-search, not re-search. Not surprisingly, newly published discovery claims and credible discoveries that appear to be important and convincing will always be open to challenge and potential modification or refutation by future researchers. Second, novelty itself frequently provokes disbelief. Nobel Laureate and physiologist Albert Szent-Györgyi once described discovery as "seeing what everybody has seen and thinking what nobody has thought." ⑧But thinking what nobody else has thought and telling others what they have missed may not change their views. Sometimes years are required for truly novel discovery claims to be accepted and appreciated. In the end, credibility "happens" to a discovery claim-a process that corresponds to what philosopher Annette Baier has described as the commons of the mind. "We reason together, challenge, revise, and complete each other's reasoning and each other's conceptions of reason."

But it takes collective scrutiny and acceptance to transform a discovery claim into a mature discovery. This is the credibility process, through which the individual researcher's me, here, now becomes the community's anyone, anywhere, anytime. Objective knowledge is the goal, not the starting point. Once a discovery claim becomes public, the discoverer receives intellectual credit. But, unlike with mining claims, the community takes control of what happens next.

Little reward accompanies duplication and confirmation of what is already known and believed. The goal is new-search, not re-search. Not surprisingly, newly published discovery claims and credible discoveries that appear to be important and convincing will always be open to challenge and potential modification or refutation by future researchers. Second, novelty itself frequently provokes disbelief. Nobel Laureate and physiologist Albert Szent-Györgyi once described discovery as "seeing what everybody has seen and thinking what nobody has thought." ⑧But thinking what nobody else has thought and telling others what they have missed may not change their views.

Which of the following would be the best title of the text?

In the idealized version of how science is done, facts about the world are waiting to be observed and collected by objective researchers who use the scientific method to carry out their work. But in the everyday practice of science, discovery frequently follows an ambiguous and complicated route. We aim to be objective, but we cannot escape the context of our unique life experience. Prior knowledge and interest influence what we experience, what we think our experiences mean, and the subsequent actions we take. Opportunities for misinterpretation, error, and self-deception abound.

What does the author say about the negative impact of smartphones?

On Jan. 9, 2007, 10 years ago today, Steve Jobs formally announced Apple's "revolutionary mobile phone" - a device that combined the functionality of an iPod, phone and Internet communication into a single unit, navigated by touch. It was a huge milestone in the development of smartphones, which are now owned by a majority of American adults and are increasingly common across the globe. As smartphones have proliferated, so have questions about their impact on how we live and how we work. Often the advantages of convenient, mobile technology are both obvious and taken for granted, leaving more subtle topics for concerned discussion: Are smartphones disturbing children's sleep? Is an inability to get away from work having a negative impact on health? And what are the implications for privacy? But today, on the 10th anniversary of the iPhone, let's take a moment to consider a less obvious advantage: the potential for smartphone technology to revolutionize behavioral science. That's because, for the first time in human history, a large proportion of the species is in continuous contact with technology that can record key features of an individual's behavior and environment. To quote a recent article published in Perspectives in Psychological Science: "Psychology has a great deal of data on what people believe they do... but little data on what people actually do." Researchers have already begun to use smartphones in social scientific research, either to query people regularly as they engage in their normal lives or to record activity using the device's built-in sensors. These studies are confirming, challenging and extending what's been found using more traditional approaches, in which people report how they behaved in real life or participate in relatively short and artificial laboratory-based tasks. To illustrate the use of smartphone-based data collection, consider a forthcoming study that combined queries embedded in everyday life with sensor data to paint a more accurate picture of how mood is affected by a person's location. The data for the study came from more than 12,000 members of the general public who downloaded a free Android app to participate in the research. Twice during the day, they were prompted to report their mood and location, with location information additionally collected from the phone's location sensors. Using both kinds of location data, the study found that people reported significantly more positive moods in locations that typically involve social interactions (such as a café or friend's house) than at home, and more positive moods at home than at work. Other studies have used sensor data to draw more subtle kinds of inferences. For instance, a study published in 2015 followed 48 students over the course of a 10-week school term. Using a combination of location, activity and audio sensors, the researchers could infer students' patterns of class attendance, study time, physical activity and socializing. These variables, in turn, predicted student GPA with surprisingly high accuracy. Another 2015 study used mobile phones to track 40 adult participants over a two-week period. Using patterns of movement and phone usage, the researchers were able to identify behaviors that predicted symptoms of depression. These studies are just first steps. As more data are collected and methods for analysis improve, researchers will be in a better position to identify how different experiences, behaviors and environments relate to each other and evolve over time, with the potential to improve people's productivity and wellbeing in a variety of domains. Beyond revealing population-wide patterns, the right combination of data and analysis can also help individuals identify unique characteristics of their own behavior, including conditions that could indicate the need for some form of intervention - such as an uptick in behaviors that signal a period of depression. Smartphone-based data collection comes at an opportune time in the evolution of psychological science. Today, the field is in transition, moving away from a focus on laboratory studies with undergraduate participants towards more complex, real-world situations studied with more diverse groups of people. Smartphones offer new tools for achieving these ambitions, offering rich data about everyday behaviors in a variety of contexts. So here's another way in which smartphones might transform the way we live and work: by offering insights into human psychology and behavior and, thus, supporting smarter social science.

What does the author say about people's views of an ideal romantic relationship?

Romantic love has clear evolutionary roots but our views about what makes an ideal romantic relationship can be swayed by the society we live in. So says psychologist Maureen O'Sullivan from the University of San Francisco. She suggests that humans have always tried to strengthen the pair-bond to maximise reproductive success. Many societies throughout history and around the world today have cultivated strong pressures to stay married. In those where ties to family and community are strong, lifelong marriages can be promoted by practices such as the cultural prohibition of divorce and arranged marriages that are seen as a contract between two families, not just two individuals. In modern western societies, however, the focus on individuality and independence means that people are less concerned about conforming to the dictates of family and culture. In the absence of societal pressures to maintain pair-bonds, O'Sullivan suggests that romantic love has increasingly come to be seen as the factor that should determine who we stay with and for how long. "That's why historically we see an increase in romantic love as a basis for forming long-term relationships," she says. According to O'Sullivan culture also shapes the sorts of feelings we expect to have, and actually do experience, when in love. Although the negative emotions associated with romantic love-fear of loss, disappointment and jealousy-are fairly consistent across cultures, the positive feelings can vary. "If you ask Japanese students to list the positive attributes they expect in a romantic partner, they rate highly things like loyalty, commitment and devotion," says O'Sullivan. "If you ask American college women, they expect everything under the suit: in addition to being committed, partners have to be amusing, funny and a friend." We judge a potential partner according to our specific cultural expectations about what romantic love should feel like. If you believe that you have found true romance, and your culture tells you that this is what a long-term relationship should be based on, there is less need to rely on social or family pressures to keep couples together. O'Sullivan argues.

What is the text mainly about?

Our "Mommy and Me" time began two years ago. My next-door neighbor and fellow mother, Christie, and I were out in our front yards, watching seven children of age 6 and under ride their bikes up and down. "I wish I could take one of my children out alone," said Christie. Then we worked out a plan: When Christie takes one of her children out, I'll watch her other three. And when she watches two of mine, I'll take someone out. The children were extremely quick to accept the idea of "Mommy and Me" time. Christie's daughter, McKenzie, went first. When she returned, the other children showered her with tons of questions. McKenzie was smiling broadly. Christie looked refreshed and happy. "She's like a different child when there's no one else around," Christie shared with me quickly. With her mother all to herself, McKenzie didn't have to make an effort to gain attention. Just as Christie had noticed changes in McKenzie, I also discovered something different in each of my children during our alone times. For example, I am always surprised when my daughter, who is seldom close to me, holds my hand frequently. My stutteringson, Tom, doesn't stutter once during our activities since he doesn't have to struggle for a chance to speak. And the other son, Sam, who's always a follower when around other children shines as a leader during our times together. The "Mommy and Me" time allows us to be simply alone and away with each child ---talking, sharing, and laughing, which has been the biggest gain. Every child deservesto be an only child at least once in a while.

Why was Brian wearing so many clothes for his travel?

Brian arrived at the San Francisco airport two hours before the flight to Paris. He was wearing three shirts, a jacket, two pairs of socks, a pair of shorts, and two pairs of jeans. He was carrying one small backpack, which was very full, but he didn't have any other luggage. Brian needed to meet a man named Tony before he checked in for his flight. He found Tony near the Air France counter. Tony gave him a round-trip ticket and a small package. "Give this package to Jean-Paul at the airport in Paris. He will have a sign with your name on it. I think you can find him easily, "Tony said." You don't have any luggage, right?" "Only this backpack," Brian answered. "You said I could bring one carry-on bag." "That's right, one carry-on bag is fine. Have a good trip." "Thanks." Is Brian a criminal? Not at all. He is an air courier. And he paid only $110 for the round-trip ticket to Paris. Air couriers get cheap airline tickets because they take important packages and papers to foreign countries. Businesses sometimes need to get packages and papers to people in foreign countries by the next day. Often, the only way they can do this is to use an air-courier company. It is not cheap for a business to send a package with an air courier, but it is quick. Every year about 80, 000 people worldwide travel as air couriers. The number of tickets for courier travel is growing by about 10 percent a year. However, air-courier travel isn't for everyone, But if you have very little money, can be flexibleabout your travel plans, and don't mind wearing the same clothes for a week, it can be a great way to take a vacation!

When John and Victoria Falls arrived in New York City for one-year stay, they did not bring very many things with them. They had planned either to live in a furnished apartment or to buy used furniture. But they soon learned about a new system that more and more people are using. The renting of home furnishings (bed, tables, dishes, and so on) has become one of America's fastest growing businesses. What kinds of people rent their home furnishings instead of buying them? People who are international business or government officials, foreign students, airline workers, young married couple - people whose job or business may force them to move frequently from one city to another. They save a lot of trouble and the cost of moving their furniture each time. They simply rent new furniture when they reach their new homes. Young people with little money do not want to buy cheap furniture that they may soon dislike. They prefer to wait until they have enough money to buy furniture that they really like. Meanwhile, they find they can rent better quality furniture than they could afford to buy. One family, who now has a large, beautiful home of their own, liked their rented furniture so much that they decided to keep renting it instead of buying new things. But usually people don't like to tell others about it. The idea of renting home furnishings is still quite new, and they are not sure what their neighbors might think.

One day a man and his daughter were going out for a walk. The man had put on a pair of odd shoes, one with a thick sole and one with a thin sole. As he came out to the street, he felt very uncomfortable. Turning to his daughter, he said: " Why should one of my legs be longer than the other one?" The daughter looked at her father's legs and said, " You have put on two odd shoes!" When he heard this, the man was very happy and thought to himself: " What a bright daughter I have got!" Then he asked his daughter to go back to the house and got him another pair of shoes. When the daughter went back to the house, all she could find was one shoe with thick sole and one with thin sole. Taking the shoes to her father, she said, " It's no use changing. These shoes are also odd, one with a thick sole and one with a thin sole." The man listened and thought to himself: " It can't help.

The author's attitude towards foreign students as mentioned in the passage is _ .

There has been a lot of unfair and biased criticism of families who welcome foreign students into their homes. I should like to tell you of my own personal experiences, which are not so different from my neighbors' experience, I might add. A host family is sent students by school or college and their homes are regularly inspected by the accommodation staff. If a home is below the required standard, the family is removed from the school's accommodation list. Apart from this, the host family is obliged to follow certain rules, as laid down by the school. The problem is that the host family cannot inspect students or refuse to accept the ones who look dirty, unreliable or noisy. And they don't seem to follow any rules at all in their behavior to the host family. We are often treated like servants or hotel staff, which is rude and bad manners. The fee paid to a host family only just covers the actual cost of providing meals etc. A hostess is lucky to make more than a pound or two "profit" on each student. One has to remember that she has to wash their clothes, allow them to have hot baths, pay for their lighting and the heating in their bedrooms, and cope with damage to furniture, bedding and carpets. Another thing is that most of them do not want to be part of the family. They prefer to be out with other students causing annoyance to local residents in the town center. They remain in their bedrooms all morning and afternoon if they can, resting before the evening so that they can go out until the early hours of the morning. Bedrooms like pigsties. Food, empty bottles and waste paper all go under the bed. When taken to task the reply is invariably that they don't understand or that the school has told them they may do as they wish. Not only that, but we have to put up with their complaints about the food, the weather and even our TV programs. It's time foreign students were taught to be polite and to behave properly, as well as how to speak English!

The main purpose of the author in writing this passage is _ .

There has been a lot of unfair and biased criticism of families who welcome foreign students into their homes. I should like to tell you of my own personal experiences, which are not so different from my neighbors' experience, I might add. A host family is sent students by school or college and their homes are regularly inspected by the accommodation staff. If a home is below the required standard, the family is removed from the school's accommodation list. Apart from this, the host family is obliged to follow certain rules, as laid down by the school. The problem is that the host family cannot inspect students or refuse to accept the ones who look dirty, unreliable or noisy. And they don't seem to follow any rules at all in their behavior to the host family. We are often treated like servants or hotel staff, which is rude and bad manners. The fee paid to a host family only just covers the actual cost of providing meals etc. A hostess is lucky to make more than a pound or two "profit" on each student.

According to paragraph 1, all of the following are needed for the growth of coral reefs except?

An important environment that is more or less totally restricted to the intertropical zone is the coral reef. Coral reefs are found where the ocean water temperature is not less than 21 °C, where there is a firm substratum, and where the seawater is not rendered too dark by excessive amounts of river-borne sediment. They will not grow in very deep water, so a platform within 30 to 40 meters of the surface is a necessary prerequisite for their development. Their physical structure is dominated by the skeletons of corals, which are carnivorous animals living off zooplankton. However, in addition to corals there are enormous quantities of algae, some calcareous, which help to build the reefs. The size of reefs is variable. Some atolls are very large-Kwajelein in the Marshall Islands of the South Pacific is 120 kilometers long and as much as 24 kilometers across-but most are very much smaller, and rise only a few meters above the water. The 2,000 kilometer complex of reefs known as the Great Barrier Reef, which forms a gigantic natural breakwater off the northeast coast of Australia, is by far the greatest coral structure on Earth. Coral reefs have fascinated scientists for almost 200 years, and some of the most pertinent observations of them were made in the 1830s by Charles Darwin on the voyage of the Beagle. He recognized that there were three major kinds: fringing reefs, barrier reefs, and atolls; and he saw that they were related to each other in a logical and gradational sequence. A fringing reef is one that lies close to the shore of some continent or island. Its surface forms an uneven and rather rough platform around the coast, about the level of low water, and its outer edge slopes downwards into the sea. Between the fringing reef and the land there is sometimes a small channel or lagoon. When the lagoon is wide and deep and the reef lies at some distance from the shore and rises from deep water it is called a barrier reef. An atoll is a reef in the form of a ring or horseshoe with a lagoon in the center. Darwin's theory was that the succession from one coral reef type to another could be achieved by the upward growth of coral from a sinking platform, and that there would be a progression from a fringing reef, through the barrier reef stage until, with the disappearance through subsidence (sinking) of the central island, only a reef-enclosed lagoon or atoll would survive. A long time after Darwin put forward this theory, some deep boreholes were drilled in the Pacific atolls in the 1950s. The drill holes passed through more than a thousand meters of coral before reaching the rock substratum of the ocean floor, and indicated that the coral had been growing upward for tens of millions of years as Earth's crust subsided at a rate of between 15 and 51 meters per million years. Darwin s theory was therefore proved basically correct. There are some submarine islands called guyots and seamounts, in which subsidence associated with sea-floor spreading has been too speedy for coral growth to keep up. Like mangrove swamps, coral reefs are extremely important habitats. Their diversity of coral genera is greatest in the warm waters of the Indian Ocean and the western Pacific. Indeed, they have been called the marine version of the tropical rain forest, rivaling their terrestrial counterparts in both richness of species and biological productivity.They also have significance because they provide coastal protection, opportunities for recreation, and are potential sources of substances like medicinal drugs. At present they are coming under a variety of threats, of which two of the most important are dredging and the effects of increased siltation brought about by accelerated erosion from neighboring land areas.

According to paragraph 4, why have coral reefs been compared to tropical rain forests?

An important environment that is more or less totally restricted to the intertropical zone is the coral reef. Coral reefs are found where the ocean water temperature is not less than 21 °C, where there is a firm substratum, and where the seawater is not rendered too dark by excessive amounts of river-borne sediment. They will not grow in very deep water, so a platform within 30 to 40 meters of the surface is a necessary prerequisite for their development. Their physical structure is dominated by the skeletons of corals, which are carnivorous animals living off zooplankton. However, in addition to corals there are enormous quantities of algae, some calcareous, which help to build the reefs. The size of reefs is variable. Some atolls are very large-Kwajelein in the Marshall Islands of the South Pacific is 120 kilometers long and as much as 24 kilometers across-but most are very much smaller, and rise only a few meters above the water. The 2,000 kilometer complex of reefs known as the Great Barrier Reef, which forms a gigantic natural breakwater off the northeast coast of Australia, is by far the greatest coral structure on Earth. Coral reefs have fascinated scientists for almost 200 years, and some of the most pertinent observations of them were made in the 1830s by Charles Darwin on the voyage of the Beagle. He recognized that there were three major kinds: fringing reefs, barrier reefs, and atolls; and he saw that they were related to each other in a logical and gradational sequence. A fringing reef is one that lies close to the shore of some continent or island. Its surface forms an uneven and rather rough platform around the coast, about the level of low water, and its outer edge slopes downwards into the sea. Between the fringing reef and the land there is sometimes a small channel or lagoon. When the lagoon is wide and deep and the reef lies at some distance from the shore and rises from deep water it is called a barrier reef. An atoll is a reef in the form of a ring or horseshoe with a lagoon in the center. Darwin's theory was that the succession from one coral reef type to another could be achieved by the upward growth of coral from a sinking platform, and that there would be a progression from a fringing reef, through the barrier reef stage until, with the disappearance through subsidence (sinking) of the central island, only a reef-enclosed lagoon or atoll would survive. A long time after Darwin put forward this theory, some deep boreholes were drilled in the Pacific atolls in the 1950s. The drill holes passed through more than a thousand meters of coral before reaching the rock substratum of the ocean floor, and indicated that the coral had been growing upward for tens of millions of years as Earth's crust subsided at a rate of between 15 and 51 meters per million years.
