Questions 36 to 45 are based on the following passage.

Individuals and businesses have legal protection for intellectual property they create and own. Intellectual property 26 from creative thinking and may include products, services, processes, and ideas. Intellectual property is protected from misappropriation (盗用). Misappropriation is taking the intellectual property of others without 27 compensation and using it for monetary gain. Legal protection is provided for the 28 of intellectual property. The three common types of legal protection are patents, copyrights, and trademarks. Patents provide exclusive use of inventions. If the U.S. Patent Office 29 a patent, it is confirming that the intellectual property is 30 . The patent prevents others from making, using, or selling the invention without the owner’s permission for a period of 20 years. Copyrights are similar to patents except that they are applied to artistic works. A copyright protects the creator of an 31 artistic or intellectual work, such as a song or a novel. A copyright gives the owner exclusive rights to copy, distribute, display, or perform the work. The copyright prevents others from using and selling the work. The 32 of a copyright is typically the lifetime of the author plus an additional 70 years. Trademarks are words, names, or symbols that identify the manufacturer of a product and __33 it from similar goods of others. A servicemark is similar to a trademark but is used to identify services. A trademark prevents others from using the 34 or a similar word, name, or symbol to take advantage of the recognition and popularity of the brand or to create confusion in the marketplace. Upon registration, a trademark is usually granted for a period of ten years. It can be 35 for additional ten-year periods indefinitely as long as the mark’s use continues.

A) due F) owners B) grants G) services C) renewed H) absolute K) results L) unique M) popularity

D) permission I) length E) distinguish J) original N) distribute O) identical Section B

Directions: In this section, you are going to read a passage with ten statements attached to it.

Each statement contains information given in one of the paragraphs. Identify the paragraph from which the information is derived. You may choose a paragraph more than once. Each paragraph is marked with a letter. Answer the questions by marking the corresponding letter on Answer Sheet 2.

Supersize Surprise

[A] Ask anyone why there is an obesity epidemic and they will tell you that it’s all down to eating too much and burning too few calories. That explanation appeals to common sense and has dominated efforts to get to the root of the obesity epidemic and reverse it. Yet obesity researchers are increasingly dissatisfied with it. Many now believe that something else must have changed in our environment to precipitate (促成) such dramatic rises in obesity over the past 40 years or so. Nobody is saying that the “big two”—reduced physical activity and increased availability of food—are not important contributors to the epidemic, but they cannot explain it all. Earlier this year a review paper by 20 obesity experts set out the 7 most plausible alternative explanations for the epidemic. Here they are. 1. Not enough sleep [B] It is widely believed that sleep is for the brain, not the body. Could a shortage of shut-eye also be helping to make us fat? Several large-scale studies suggest there may be a link. People who sleep less than 7 hours a night tend to have a higher body mass index than people who sleep more, according to data gathered by the US National Health and Nutrition Examination Survey. Similarly, the US Nurses’ Health Study, which tracked 68,000 women for 16 years, found that those who slept an average of 5 hours a night gained more weight during the study period than women who slept 6 hours; who in turn gained more than those who slept 7. [C] It’s well known that obesity impairs sleep, so perhaps people get fat first and sleep less afterwards. But the nurses’ study suggests that it can work in the other direction too: sleep loss may precipitate weight gain. Although getting figures is difficult, it appears that we really are sleeping less. In 1960 people in the US slept an average of 8.5 hours per night. A 2002 poll by the National Sleep Foundation suggests that the average has fallen to under 7 hours, and the decline is mirrored by the increase in obesity. 2. Climate control [D] We humans, like all warm-blooded animals, can keep our core body temperatures pretty much constant regardless of what’s going on in the world around us. We do this by altering our metabolic (新陈代谢的) rate, shivering or sweating. Keeping warm and staying cool take energy unless we are in the “thermo-neutral zone”, which is increasingly where we choose to live and work. [E] There is no denying that ambient temperatures (环境温度) have changed in the past few decades. Between 1970 and 2000, the average British home warmed from a chilly 13℃ to 18℃. In the US, the changes have been at the other end of the thermometer as the proportion of homes with air conditioning rose from 23% to 47% between 1978 and 1997. In the southern states—where obesity rates tend to be highest—the number of houses with air conditioning has shot up to 70% from 37% in 1978.

[F] Could air conditioning in summer and heating in winter really make a difference to our weight? Sadly, there is some evidence that it does—at least with regard to heating. Studies show that in comfortable temperatures we use less energy. 3. Less smoking [G] Bad news: smokers really do tend to be thinner than the rest of us, and quitting really does pack on the pounds, though no one is sure why. It probably has something to do with the fact that nicotine (尼古丁) is an appetite suppressant and appears to up your metabolic rate. [H] Katherine Flegal and colleagues at the US National Center for Health Statistics in Hyattsville, Maryland, have calculated that people kicking the habit have been responsible for a small but significant portion of the US epidemic of fatness. From data collected around 1991 by the US National Health and Nutrition Examination Survey, they worked out that people who had quit in the previous decade were much more likely to be overweight than smokers and people who had never smoked. Among men, for example, nearly half of quitters were overweight compared with 37% of non-smokers and only 28% of smokers. 4. Genetic effects [I] Your chances of becoming fat may be set, at least in part, before you were even born. Children of obese mothers are much more likely to become obese themselves later in life. Offspring of mice fed a high-fat diet during pregnancy are much more likely to become fat than the offspring of identical mice fed a normal diet. Intriguingly, the effect persists for two or three generations. Grand-children of mice fed a high-fat diet grow up fat even if their own mother is fed normally—so your fate may have been sealed even before you were conceived. 5. A little older … [J] Some groups of people just happen to be fatter than others. Surveys carried out by the US National Center for Health Statistics found that adults aged 40 to 79 were around three times as likely to be obese as younger people. Non-white females also tend to fall at the fatter end of the spectrum: Mexican-American women are 30% more likely than white women to be obese, and black women have twice the risk. [K] In the US, these groups account for an increasing percentage of the population. Between 1970 and 2000 the US population aged 35 to 44 grew by 43%. The proportion of Hispanic-Americans also grew, from under 5% to 12.5% of the population, while the proportion of black Americans increased from 11% to 12.3%. These changes may account in part for the increased prevalence of obesity. 6. Mature mums [L] Mothers around the world are getting older. In the UK, the mean age for having a first child is 27.3, compared with 23.7 in 1970. Mean age at first birth in the US has also increased, rising from 21.4 in 1970 to 24.9 in 2000. [M] This would be neither here nor there if it weren’t for the observation that having an older mother seems to be an independent risk factor for obesity. Results from the US National Heart, Lung and Blood Institute’s study found that the odds of a child being obese increase about 14% for every five extra years of their mother’s age, though why this should be so is not entirely clear. [N] Michael Symonds at the University of Nottingham, UK, found that first-born children have more fat than younger ones. As family size decreases, firstborns account for a greater share of the population. In 1964, British women gave birth to an average of 2.95 children; by 2005 that figure had fallen to 1.79. In the US in 1976, 9.6% of women in their 40s had had only one child; in

2004 it was 17.4%. This combination of older mothers and more single children could be contributing to the obesity epidemic. 7. Like marrying like [O] Just as people pair off according to looks, so they do for size. Lean people are more likely to marry lean and fat more likely to marry fat. On its own, like marrying like cannot account for any increase in obesity. But combined with others — particularly the fact that obesity is partly genetic, and that heavier people have more children — it amplifies the increase from other causes.

36. The effect of nicotine suppresses the appetite of smokers.

37. According to the US National Center for Health Statistics, the increased obesity in the US is a

result of the rising proportion of minorities in its population.

38. According to Michael Symonds, one factor contributing to the obesity epidemic is the decrease

of family size.

39. Indoor heating affect our life in that it contributes to our weight gain. 40. The review is mainly about new explanations for the obesity epidemic.

41. Those who quit smoking are most likely to be overweight according to Katherine Flegal’s

study.

42. In the US Nurses’ Health Study, women who slept an average of 7 hours a night gained the least weight.

43. When two heavy people get married, chances of their children getting fat increase, because obesity is partly genetic.

44. The popular belief about obesity is that it causes sleep loss.

45. According to the US National Heart, Lung and Blood Institute, the reason why older mothers’ children tend to be obese remains unclear. Section C

Directions: There are 2 passages in this section. Each passage is followed by some questions or

unfinished statements. For each of them there are four choices marked A), B), C) and D). You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the centre.

Passage One

Questions 46 to 50 are based on the following passage.

Imagine eating everything delicious you want—with none of the fat. That would be great, wouldn’t it?

New “fake fat” products appeared on store shelves in the United States recently, but not everyone is happy about it. Makers of the products, which contain a compound called olestra, say food manufacturers can now eliminate fat from certain foods. Critics, however, say the new compound can rob the body of essential vitamins and nutrients (营养物) and can also cause unpleasant side effects in some people. So it’s up to consumers to decide whether the new fat-free products taste good enough to keep eating.

Chemists discovered olestra in the late 1960s, when they were searching for a fat that could be digested by infants more easily. Instead of finding the desired fat, the researchers created a fat that can’t be digested at all.

Normally, special chemicals in the intestines (肠) “grab” molecules of regular fat and break them down so they can be used by the body. A molecule of regular fat is made up of three

molecules of substances called fatty acids.

The fatty acids are absorbed by the intestines and bring with them the essential vitamins A, D, E, and K. When fat molecules are present in the intestines with any of those vitamins, the vitamins attach to the molecules and are carried into the bloodstream.

Olestra, which is made from six to eight molecules of fatty acids, is too large for the intestines to absorb. It just slides through the intestines without being broken down. Manufacturers say it’s that ability to slide unchanged through the intestines that makes olestra so valuable as a fat substitute. It provides consumers with the taste of regular fat without any bad effects on the body. But critics say olestra can prevent vitamins A, D, E, and K from being absorbed. It can also prevent the absorption of carotenoids (类胡萝卜素), compounds that may reduce the risk of cancer, heart disease, etc.

Manufacturers are adding vitamins A, D, E, and K as well as carotenoids to their products now. Even so, some nutritionists are still concerned that people might eat unlimited amounts of food made with the fat substitute without worrying about how many calories they are consuming. 46. We learn from the passage that olestra is a substance that ______.

A) contains plenty of nutrients

B) renders foods calorie-free while retaining their vitamins C) makes foods easily digestible

D) makes foods fat-free while keeping them delicious

47. The result of the search for an easily digestible fat turned out to be ______.

A) commercially useless B) just as anticipated C) somewhat controversial D) quite unexpected 48. Olestra is different from ordinary fats in that ______.

A) it passes through the intestines without being absorbed B) it facilitates the absorption of vitamins by the body C) it helps reduce the incidence of heart disease D) it prevents excessive intake of vitamins

49. What is a possible negative effect of olestra according to some critics?

A) It may impair the digestive system. B) It may affect the overall fat intake. C) It may increase the risk of cancer. D) It may spoil the consumers’ appetite. 50. Why are nutritionists concerned about adding vitamins to olestra?

A) It may lead to the over-consumption of vitamins. B) People may be induced to eat more than is necessary. C) The function of the intestines may be weakened. D) It may trigger a new wave of fake food production.

Passage Two

Questions 51 to 55 are based on the following passage.

Bill Gates, the billionaire Microsoft chairman without a single earned university degree, is by his success raising new doubts about the worth of the business world’s favorite academic title: the MBA (Master of Business Administration).

The MBA, a 20th-century product, always has borne the mark of lowly commerce and greed (贪婪) on the tree-lined campuses ruled by purer disciplines such as philosophy and literature.

But even with the recession apparently cutting into the hiring of business school graduates, about 79,000 people are expected to receive MBAs in 1993. This is nearly 16 times the number of

business graduates in 1960, a testimony to the widespread assumption that the MBA is vital for young men and women who want to run companies some day.

“If you are going into the corporate world it is still a disadvantage not to have one,” said Donald Morrison, professor of marketing and management science. “But in the last five years or so, when someone says, ‘Should I attempt to get an MBA,’ the answer a lot more is: It depends.”

The success of Bill Gates and other non-MBAs, such as the late Sam Walton of Wal-Mart Stores Inc, has helped inspire self-conscious debates on business school campuses over the worth of a business degree and whether management skills can be taught.

The Harvard Business Review printed a lively, fictional exchange of letters to dramatize complaints about business degree holders.

The article called MBA hires “extremely disappointing” and said “MBAs want to move up too fast, they don’t understand politics and people, and they aren’t able to function as part of a team until their third year. But by then, they’re out looking for other jobs.”

The problem, most participants in the debate acknowledge, is that the MBA has acquired an aura (光环) of future riches and power far beyond its actual importance and usefulness.

Enrollment in business schools exploded in the 1970s and 1980s and created the assumption that no one who pursued a business career could do without one. The growth was fueled by a backlash (反冲) against the anti-business values of the 1960s and by the women’s movement.

Business people who have hired or worked with MBAs say those with the degrees often know how to analyze systems but are not so skillful at motivating people. “They don’t get a lot of grounding in the people side of the business,” said James Shaffer, vice-president and principal of the Towers Perrin management consulting firm.

51. According to Paragraph 2, what is the general attitude towards business on campuses

dominated by purer disciplines? A) Scornful. B) Appreciative. C) Envious. D) Realistic.

52. It seems that the controversy over the value of MBA degrees has been fueled mainly by

______.

A) the complaints from various employers B) the success of many non-MBAs

C) the criticism from the scientists of purer disciplines D) the poor performance of MBAs at work

53. What is the major weakness of MBA holders according to The Harvard Business Review?

A) They are usually self-centered. B) They are aggressive and greedy.

C) They keep complaining about their jobs. D) They are not good at dealing with people.

54. From the passage we know that most MBAs ______.

A) can climb the corporate ladder fairly quickly

B) quit their jobs once they are familiar with their workmates C) receive salaries that do not match their professional training D) cherish unrealistic expectations about their future 55. What is the passage mainly about?

A) Why there is an increased enrollment in MBA programs.

B) The necessity of reforming MBA programs in business schools.

C) Doubts about the worth of holding an MBA degree. D) A debate held recently on university campuses.

True Friendship

As a human being, one can hardly do without a friend. Just as air, water and food are vital to a human being, friends are of the same importance. Firstly, everyone lives in a community and doesn’t expect to isolate from the society. Secondly, a true friend can do lots of good to a person in his whole life. Everyone may have his own opinion on true friendship, but we all accept the popular saying: a friend in need is a friend indeed. Along this line of consideration, a true friend should not be always a hanger-on but one who can provide timely help. Also, a true friend should be always faithful to his confidant. Those who hit at a friend when he is in depression will be disdained forever. Therefore, a true friend would never be a betrayer. I do have some good friends. They always encourage me when I feel frustrated. Their material and spiritual aids greatly activate me and help me overcome all kinds of difficulties. So I believe that a friend is a person we can always turn to for support whatever happens. ★ Part III Section A 36~40 KAFBL Section B 36~40 GKNFA Section C 46～50 DDACB 51～55 ABDDC ★ Part IV Translation Alcohol has maintained an important role in Chinese history.
