Article: We've all heard about the power of positive thinking, but a recent study found that people who think they're getting fit actually get more positive benefits from activity, according to a Reuters Health article. The study examined hotel housekeepers over a period of four weeks. Some of the housekeepers were told that their work duties gave them enough activity to meet the Surgeon General's health guidelines . Another group of housekeepers were told nothing. After four weeks, the housekeepers who believed their work activity counted as exercise lost weight and body fat, and their blood pressure went down. The results of this study suggest that it's important to understand and believe in the positive benefits of your activity. So here are a few things to think about the next time you exercise: Just thirty minutes of quick walking each day can greatly reduce your risk of a heart attack. Even your housework -- like yard work and house cleaning -- can help you burn calories and increase your fitness levels. Weight bearing activity just a few times a week can build bone density and reduce your chances of developing osteoporosis . Three 10-minute workouts throughout the day are just as good to your health as one long workout. Moderate amounts of exercise have been linked to lower rates of heart disease, stroke and even cancer. Strength training can help make daily activities like carrying bags or laundry feel easier. Regular exercise will reduce stress, keep you in a good mood and improve the quality of your sleep. Question: Which of the following is NOT the suggested things to think about when you exercise? - Housework helps burn calories. - Regular exercise leads to better sleep. - Weight bearing activity does good to people.[:ZXXK] - Walking a dog reduces the chance of a heart disease.
Walking a dog reduces the chance of a heart disease.

Read the following article and select the best answer. Article: Do we think only with the brain? Hardly. The brain is like a telephone exchange. It is the switchboard, but not the whole system. Its function is to receive incoming signals, make proper connections, and send the messages through to their destination. For efficient service, the body must function as a whole. But where is the "mind"? Is it in the brain or perhaps in the nervous system? After all, can we say that the mind is in any particular place? It is not a thing, like a leg, or even the brain. It is a function, an activity. Aristotle, twenty-three hundred years ago, observed that the mind was to the body what cutting was to the ax. When the ax is not in use, there is no cutting. So it is with the mind. "Mind," said Charles H. Woolbert, "is what the body is doing." If this activity is necessary for thinking, it is also necessary for carrying thought from one person to another. Observe how people go about the business of ordinary conversation. If you have never done this carefully, you have a surprise in store, for good conversationalists are almost constantly in motion. Their heads are continually nodding and shaking sometimes so vigorously that you wonder how their necks can stand the strain. Even the legs and feet are active. As for the hands and arms, they are seldom still for more than a few seconds at a time. These people, remember, are not making speeches. They are only common people trying to make others understand what they have in mind. They are not conscious of movement. Their speech is not studies. They are just human creatures in a human environment, trying to adapt themselves to a social situation. Yet they converse, not only with oral language, but with visible actions that involve practically every muscle in the body. In short, because people really think all over, a speaker must talk all over if he succeeds in making people think. Question: Which of the following is the best title for the passage? - Bodily Communication - Spoken Language - Bodily Actions - Conversations

Q: Read the following article and select the best answer. Article: For high school leavers starting out in the working world,it is very important to learn particular skills and practice how to behave in an interview or how to find all internship .In some countries,schools have programs to help students onto the path to work.In the Unites States,however,such programs are still few and far between. Research shows that if high schools provide career-related courses,students are likely to get higher earnings in later years.The students are more likely to stay in school,graduate and go on to higher education. In Germany,students as young as 13 and 14 are expected to do internships.German companies work with schools to make sure that young people get the education they need for future employment. But in America, education reform programs focus on how well students do in exams instead of bringing them into contact with the working world.Harvard Education school professor Robert Schwartz has criticized education reformers for trying to place all graduates directly on the four-year college track.Schwartz argued that this approach leaves the country's most vulnerable kids with no jobs and no skills. Schwartz believed that the best career programs encourage kids to go for higher education while also teaching them valuable practical skills at high sch001.James Madison High School in New York,for example,encourages students to choose classes on career--based courses.The school then helps them gain on--the-job experience in those fields while they're still at high school. However,even for teens whose schools encourage them to connect with work,the job market is daunting.In the US,unemployment rates for 16-to 19-year-olds are above 20 percent for the third summer in a row. "The risk is that if teenagers miss out on the Summer job experience,they become part of this generation of teens who had trouble in landing a job,"said Michael,a researcher in the US. Question: In the author's opinion.American high school leavers _ . - have enough career-related courses - need more career advice from their schools - perform better in exams than German students - can get higher earnings in later years
A: need more career advice from their schools

Read the following article and select the best answer. Article: As if there weren't enough of them in the world already, scientists have succeeded in cloning flies. The alike fruit flies are the first insects ever cloned, says the Canadian team that created them. The question everyone asks is why anyone would want to clone flies in the first place. She hopes that the insects , which are very easy to experiment with , will help to adjust the cloning process in other animals and even in humans, where the technique is being researched to aid production of therapeutic stem cells. In cloning, the DNA-containing nucleus of an adult cell is injected into an egg whose own nucleus has been removed. At the moment, the majority of cloned mice, sheep and other animals die before birth. It is thought this is because the adult DNA is not properly 'reprogrammed'. Using flies, researchers might discover genes that are important for this reprogramming, and that have matches in other animals. That is because it is relatively easy in flies to knock out the function of a single gene and then attempt cloning with these cells, which will test whether that gene is important. If such genes are confirmed, then in theory cloned mammalian embryos might be grown in selected solutions that change the activity of those genes to improve the technique's success rate. Although some groups have attempted to clone insects before, Lloyd says this is the first time it has been successful. The team used a slight difference on the standard cloning process: they transferred nuclei taken from embryos rather than fully-grown adult cells. They sucked several nuclei (pl)out of developing fly embryos, and injected them into a fertilized fly egg. From over 800 early attempts, they cloned five adult insects, the group reports in the journal Genetics. Question: The failure of most cloned animals is due to _ . - the difference of other animals' genes - the improper technique of clone - the complex of other animals - the improper rearrange of the adult gene
(A).
the improper rearrange of the adult gene
