Q: I'm taking a test and have to guess the right answer to the question after the article. Article: The canopy, the upper level of the trees in the rain forest, holds too much of climbing mammals of moderately large size, which may include monkeys, cats, civets, and porcupines. Smaller species, including such as nice and small squirrels, are not as common overall in high tropical canopies as they are in most habitats globally. Small mammals, being warm blooded, suffer hardship in the exposed and uncertain environment of the uppermost trees. Because a small body has more surface area per unit of weight than a large one of similar shape, it gains or loses heat more rapidly. Thus, in the trees, where protection from heat and cold may be scarce and conditions may be changeable, a small mammal may have trouble maintaining its body temperature. Small size makes it easy to scramble among twigs and branches in the canopy for insects, flowers, or fruit, but small mammals are defeated, in the competition for food, by large ones that have their own strategies for browsing among tbod-rich twigs. The weight of an ape hanging below a branch draws the leaves down so that fruit-bearing leaves drop toward the ape's face. Walking or leaping species of a similar or even larger size access the outer twigs either by breaking and gaining the whole branch or by catching hold of hard branches with the feet or tail and picking food with their hands. Small climbing animals may reach twigs readily, but it is harder for them than for large climbing animals to cross the wide gaps from one tree top to the next that typify the high canopy. A gibbon can hurl itself farther than a mouse can: it can achieve a running start, and it can more effectively use a branch as a springboard . The forward movement of a small animal is seriously reduced by the air friction against the ly large surface area of its body. Question: Which of the following questions does the passage answer? Options: A: How is the rain forest different from other habitats? B: How does an animal's body size influence an animal's need for food? C: Why does rain forest provide an unusual variety of food for animals? D: Why do large animals tend to dominate the upper canopy of the rain forest?
A: D

Q: I'm taking a test and have to guess the right answer to the question after the article. Article: Dear editor, I am writing to ask what has happened to our young people.They are not as polite or hard-working as my generation(I will give you two examples. Last Friday, I got on the underground at 9:15 a.m. It was very crowded so there was no free seat.There were some boys sitting on the seats near me.I didn't know why they were not at school.They were talking and laughing loudly. It was difficult for me to read my newspaper with all the noise.At the next stop, a pregnant woman and her daughter got on with lots of shopping bags.I expected the boys to let them sit down.They saw the woman but they did nothing.I had to ask them to give the woman and her daughter seats. They did so but gave me a rude look. Last Saturday, I had dinner with my friend's family.I was glad to see his children, who I hadn't seen for ten years.During the dinner, I started talking about world politics with the children.It soon became clear that they didn't know much about it.They couldn't tell me the name of the King of Spain or President of Italy.All they knew about was the Internet or which singers were the most beautiful.In my days, students knew the kings, the queens and the presidents of every country in Europe. I worry about the future of Germany.How could these young people become good workers and parents? They sit around McDonald's after school instead of going to the library like I did at their age.Maybe they have too much money.Perhaps some readers can give us some ideas about what to do with this "lost generation". Yours sincerely, Frantz Vogts. Question: By saying "lost generation", Mr Vogts refers to _ . Options: A: the fact that he is angry with young people today B: the people at his age C: his worry about these young people D: today's young people
A: D

Q: I'm taking a test and have to guess the right answer to the question after the article. Article: Every year, it costs British students more and more to attend university. Students are graduating with larger and larger debts. So is a college degree really worth it? In 2006, the UK government started to allow universities in England and Wales to charge British students tuition fees. As a result, more than 80 percent of students in England and Wales now take out a student loan in order to go to university. They use the loan to pay for tuition fees and living expenses. Although the interest on student loans is quite low, it begins as soon as the student receives the loan. The average student in England and Wales now graduates from university with a debt of around PS12,000 (122,952 yuan). It means graduates have to struggle to pay rent on a flat, because they have to start paying back the student loan when they reach April after graduating. If you start to earn over PS15,000 (153,630 yuan) a year, the government takes repayments directly from your monthly salary. You might think that a person with a degree would find it easy to get a well-paid job. However, most people in "white collar jobs" seem to have a degree, so there is a lot of competition. Also, British companies tend to value work experience over . All of the above is beginning to make British people question whether a university degree is really worth the money. Even before the credit crisis started, the BBC stated: "The number of British students at UK universities has fallen for the first time in recent history, from 1.97 million in 2007 to 1.96 million last year." Meanwhile, the British universities offer more and more of the available places to richer international students rather than poorer British students. What does the future hold for British higher education? Question: Which of the following can be the best title of the passage? Options: A: More Profits for the Banks B: College Life in the UK C: Welcome! International Students D: UK Universities Students Become Poorer
A: D

Q: I'm taking a test and have to guess the right answer to the question after the article. Article: The next generation of smart phone could combine the date from its gyroscopes with a built-in compass to allow you to track your indoor movements even without GPS. Research described it in the international Journal of Innovative Computing and Applications by Shahid Ayub of Lancaster University, and his colleagues there and at HW Communications, suggests that the embedded inertial sensors in many smart phones have added the facility to be used for localization and tracking applications. The primary benefit of using smart phones is that no additional infrastructure would need to be installed for monitoring personnel movements in a wide variety of situations not least staff, equipment and inventory movements in warehouse facilities, shopping malls and factories. In contrast, other technology being proposed would require new equipment,such as RFID technologies. However, smart phones do not yet have the ability to pinpoint their location without recourse to the GPS system, which is not accessible indoors and has the added disadvantage of using up battery power very quickly even if it could be used. Inertial navigation only provides the necessary information to a specified starting point the team says. This is useful for anyone with a non-GPS smart phone who wishes to track the route they take when walking or jogging if they specify their starting point. The team suggests that pedestrians indoors could be positioned using a combination of the smart phone accelerometer and an built-in digital compass, something that will become available in future smart phones. They have now investigated the potential of three different smart phone placement modes: idle, hand held and listening, which could be used with pedestrian dead reckoning (PDR) techniques to allow users to record the path they follow or for various kinds of workplace or other monitoring requirements. "The technique could be used in underground tube stations, airports , train stations where there is no infrastructure installed for tracking or... Question: We can learn from the passage that the recent studies of smart phones _ . Options: A: were conducted by Shahid Ayub alone B: were supported by GPS C: have no connection with everyday needs D: can be applied to underground tube stations
