Reading Comprehension (30 points)Directions: There are 4 passages in this part. 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 the ANSWER SHEET with a single line through the center.Passage OneHow do people image life in the United States in the future? Below are some predictions made by Richard N. Farmer, who gave his light-hearted opinion of the “World of 2084.”Since no one wants to do the dirty, uninteresting factory-line work any more, we decide not to. So we take some chimpanzees（黑猩猩）, or if we really want some strength, some great apes (猿), do a bit of scientific engineering here and there, and we create some animals, which are made for the factory line. They work their eight hours a day, and don’t mind the repetition a bit.Jack Baxter, a common American of 2084, glanced at his stop-watch. He was slowing down; he could only run the kilometer in four minutes flat now, and when he was 80, he could do it in three-fifty. But, being 140 years old made a difference, regardless of what his doctor said. Jack had received his first cancer shot in 1981; he had received his man-made heart in 2014, before they really got those human ones perfected, so he wasn’t a very good example of a complete human. But he felt pretty good; he had been one of the lucky ones, who had received his shots to make him young again before he turned 40, so he was still a young-looking fellow. Of course, he looked old in his world, since no one got much beyond 30-looking any more. And, of course, he would die; right now, fellows pushing 200 were in poor shape and kicking off.61. Who is NOT likely to do factory-line work in the future according to Farmer?A) humans B) chimpanzees C) apes D) dogs62. Why was Jack Baxter not a very good example of a complete human?A)Because he is too old.B)Because he had a cancer shot when he was young.C)Because his heart was man-made.D)Because he looked older than other people.63. Why did Jack still look young at such an old age?A)Because everybody looked young in his world.B)Because he received a shot before 40.C)Because he had a young heart.D)Because he did exercise every day.64. What did Jack’s doctor probably tell him?A) A 140-year-old can do what an 80-year-old does.B)He could run the kilometer within four minutes.C)It’s natural that you will slow down as you grow old.D)Running fast is good to his health.65. What does “kick off” (the last two words) probably mean?A) do sports B) exercise C) take flights D) diePassage TwoThere is much discussion today about whether economic growth is desirable. At an earlier period, our desire for material wealth may have been justified. Now, however, this desire for more than we need is causing serious problems. Even though we have good intentions, we may be producing too much, too fast.Those who criticize economic growth argue that we must slow down. They believe that society is approaching certain limits on growth. These include the fixed supply of natural resources, the possible negative effects of industry on the natural environment, and the continuing increase in the world’s population. As society reaches these limits, economic growth can no longer continue, and the quality of life will decrease.People who want more economic growth, on the other hand, argue that even at the present growth rate there are still many poor people in the world. These proponents of economic growth believe that only more growth can create the capital needed to improve the quality of life in the world. Furthermore, they argue that only continued growth can provide the financial resources required to protect our natural surroundings from industrialization.This debate over the desirability of continued economic growth is of vital importance to business and industry. If those who argue against economic growth are correct, the problems they mention cannot be ignored. To find a solution, economists and the business community must pay attention to these problems and continue discussing them one another.66. According to those who argue against economic growth, we should slow down for the following reasons EXCEPT that ____.A)the world population is ever increasingB)our natural surroundings are in danger of being destroyed by industryC)the fixed supply of natural resources marks a point beyond which economic growth cannot continueD)more efforts should be made to improve the quality of our material life67. Those who want more economic growth believe that continued economic growth ____.A)can provide the solution to all our social problems todayB)can provide us with more natural resources for industrializationC)can protect our environment from being polluted by industryD)is essential to the well-being of society as a whole68. According to the context, the word “proponents” (Line 2, Para. 3) most probably refers to ____.A)disagreementsB)arguments in support of somethingC)people who argue for somethingD)people who argue against something69. What is the main topic of the passage?A)The advantages and disadvantages of economic growth.B)The present debate on economic growth.C)The contradiction between economists and the business community.D)The importance of the debate on economic growth.70. We can infer from the passage that the author’s attitude towards the economic growth is ____.A) a matter of factB)affirmativeC)negativeD)worriedPassage ThreeTime spent in bookshop can be most enjoyable, whether you are a book-lover or merely you are there to buy a present. You may even have entered the shop just to find shelter from a sudden shower. Whatever the reason, you can soon become totally unaware of your surroundings. The desire to pick up a book with an attractive “dust-jacket” is irresistible, although this method of selection ought not to be followed, as you might end up with a rather dull book. You soon become engrossed in some book or other, and usually it is only much later that you realize you have spent far too much time there and must dash off to keep some forgotten appointment---without buying a book, of course.This opportunity to escape the realities of everyday life is, I think, the main attraction of a bookshop. There are not many places where it is possible to do this. A music shop is very much like a bookshop. You can wander round such places to your heart’s content. If it is a good shop, no assistant will approach you with inevitable greeting: “Can I help you, sir?” You needn’t buy anything you don’t want. In a bookshop an assistant should remain in the background until you have finished browsing. Then, and only then, are his services necessary. Of course you may want to find out where a particular section is, but when he has led you there, the assistant should retire carefully and look as if he is not interested in selling a single book.You have to be careful not to be attracted by the variety of books in a bookshop. It is very easy to enter the shop looking for a book on ancient coins and to come out carrying a copy of the latest best-selling novel and perhaps a book about brass-rubbing---something that had only vaguely interested you up until then. This volume on the subject, however, happened to be so well illustrated and the part of the text you read proved so interesting that you just had to buy it. This sort of thing can be very dangerous. Apart from running up a huge account, you can waste a great deal of time wandering from section to section.71. What does “dust-jacket” in the first paragraph probably mean?A)The title of a book.B) A kind of clothes.C)Book cover full of dust.D)Protecting paper cover of a book.72. In the author’s opinion, what is the main attraction of a bookshop?A)You can spend much time in the bookshop.B)It has many books with attractive dust-jacket.C)It enables you to forget the realities of everyday life.D)You don’t have to go for unpleasant appointments.73. According to the passage, what will happen in a good bookshop?A)Nobody will take notice of you.B)You will feel as if you were in a music shop.C)You will find yourself undisturbed and satisfied with your own browsing.D)The assistant will greet and treat you in a very friendly way.74. The author thinks that the service of the bookshop assistant is needed ____.A)as soon as you enter the shopB)before you start your browsingC)only when you have finished your browsingD)after you have made your final decision75. Picking up books that vaguely interest you can be dangerous because ___.A)you may forget about the book you plan to buyB)it costs you too much money and timeC)it makes you break your appointmentD)you have to give up the best-selling bookPassage FourAll research to date on body image shows that women are much more critical of their appearance than men---much less likely to admire what they see in the mirror. Up to 8 out of 10 women are dissatisfied with their reflection, and more than half may see a distorted image.Men looking in the mirror are more likely to be either pleased with what they see or indifferent. Research shows that men generally have a much more positive body-image than women---if anything, they may tend to overestimate their attractiveness. Some men looking in the mirror may literally not see the flaws in their appearance.Why are women so much more self-critical than men? Because women are judged on their appearance more than men, and standards of female beauty are considerably bombarded with images of the “ideal” face. And constant exposure to idealized images of female beauty on TV, magazines and billboards makes exceptional good looks seem normal and anything short of perfection seem abnormal and ugly. It has been estimated that young women now see more images of outstandingly beautiful women in one day than our mothers saw through their entire adolescence. Also, most women are trying to achieve the impossible: standards of female beauty have in fact become progressively more unrealistic during the last century. In 1917, the physically perfect woman was about 5ft 4 in tall and weighed nearly 10 stone. Even 25 years ago, top models and beauty queens weighed only 8% less than the average woman. Now they weigh 23% less. The current media ideal for women is achievable by less than 5% of the female population---and that’s just in terms of weight and size. If you want the ideal shape, face, etc., it’s probably more like 1%.76. The main purpose of the passage is to _____.A)explain a phenomenonB)compare two factsC)make a suggestionD)strengthen a current theory77. The difference between men and women when they look into the mirror is that _____.A)women stay longer before the mirror than menB)women feel more comfortable about their appearance than menC)women, more than men, come away from the mirror feeling unsatisfiedD)women’s looks before the mirror appear more distorted than men’s78. The phrase “bombarded with” (Line 2, Para. 3) could best be replaced by ____.A)deniedB)doubtful ofC)very proud ofD)influenced by79. Which of the following can be inferred about the physically perfect woman in 1917?A)She was not very much different from the average woman.B)She was hardly achievable by the female population.C)She looked into the mirror more often than women today.D)She was regarded perfect only in terms of her face.80. Today’s perfect woman is achievable, in terms of every physical aspect, by ___ of the female population.A) 23% B) 8% C) 5% D) 1%Part IV.

Reading Comprehension (30 points)Directions: There are 4 passages in this part. 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 the ANSWER SHEET with a single line through the center.Passage OneHow do people image life in the United States in the future? Below are some predictions made by Richard N. Farmer, who gave his light-hearted opinion of the “World of 2084.”Since no one wants to do the dirty, uninteresting factory-line work any more, we decide not to. So we take some chimpanzees（黑猩猩）, or if we really want some strength, some great apes (猿), do a bit of scientific engineering here and there, and we create some animals, which are made for the factory line. They work their eight hours a day, and don’t mind the repetition a bit.Jack Baxter, a common American of 2084, glanced at his stop-watch. He was slowing down; he could onlyrun the kilometer in four minutes flat now, and when he was 80, he could do it in three-fifty. But, being 140 years old made a difference, regardless of what his doctor said. Jack had received his first cancer shot in 1981; he had received his man-made heart in 2014, before they really got those human ones perfected, so he wasn’t a very good example of a complete human. But he felt pretty good; he had been one of the lucky ones, who had received his shots to make him young again before he turned 40, so he was still a young-looking fellow. Of course, he looked old in his world, since no one got much beyond 30-looking any more. And, of course, he would die; right now, fellows pushing 200 were in poor shape and kicking off.61. Who is NOT likely to do factory-line work in the future according to Farmer?A) humans B) chimpanzees C) apes D) dogs62. Why was Jack Baxter not a very good example of a complete human?A)Because he is too old.B)Because he had a cancer shot when he was young.C)Because his heart was man-made.D)Because he looked older than other people.63. Why did Jack still look young at such an old age?A)Because everybody looked young in his world.B)Because he received a shot before 40.C)Because he had a young heart.D)Because he did exercise every day.64. What did Jack’s doctor probably tell him?A) A 140-year-old can do what an 80-year-old does.B)He could run the kilometer within four minutes.C)It’s natural that you will slow down as you grow old.D)Running fast is good to his health.65. What does “kick off” (the last two words) probably mean?A) do sports B) exercise C) take flights D) diePassage TwoThere is much discussion today about whether economic growth is desirable. At an earlier period, our desire for material wealth may have been justified. Now, however, this desire for more than we need is causing serious problems. Even though we have good intentions, we may be producing too much, too fast.Those who criticize economic growth argue that we must slow down. They believe that society is approaching certain limits on growth. These include the fixed supply of natural resources, the possible negative effects of industry on the natural environment, and the continuing increase in the world’s population. As society reaches these limits, economic growth can no longer continue, and the quality of life will decrease.People who want more economic growth, on the other hand, argue that even at the present growth rate there are still many poor people in the world. These proponents of economic growth believe that only more growth can create the capital needed to improve the quality of life in the world. Furthermore, they argue that only continued growth can provide the financial resources required to protect our natural surroundings from industrialization.This debate over the desirability of continued economic growth is of vital importance to business and industry. If those who argue against economic growth are correct, the problems they mention cannot be ignored. To find a solution, economists and the business community must pay attention to these problems and continuediscussing them one another.66. According to those who argue against economic growth, we should slow down for the following reasons EXCEPT that ____.A)the world population is ever increasingB)our natural surroundings are in danger of being destroyed by industryC)the fixed supply of natural resources marks a point beyond which economic growth cannot continueD)more efforts should be made to improve the quality of our material life67. Those who want more economic growth believe that continued economic growth ____.A)can provide the solution to all our social problems todayB)can provide us with more natural resources for industrializationC)can protect our environment from being polluted by industryD)is essential to the well-being of society as a whole68. According to the context, the word “proponents” (Line 2, Para. 3) most probably refers to ____.A)disagreementsB)arguments in support of somethingC)people who argue for somethingD)people who argue against something69. What is the main topic of the passage?A)The advantages and disadvantages of economic growth.B)The present debate on economic growth.C)The contradiction between economists and the business community.D)The importance of the debate on economic growth.70. We can infer from the passage that the author’s attitude towards the economic growth is ____.A) a matter of factB)affirmativeC)negativeD)worriedPassage ThreeTime spent in bookshop can be most enjoyable, whether you are a book-lover or merely you are there to buy a present. You may even have entered the shop just to find shelter from a sudden shower. Whatever the reason, you can soon become totally unaware of your surroundings. The desire to pick up a book with an attractive “dust-jacket” is irresistible, although this method of selection ought not to be followed, as you might end up with a rather dull book. You soon become engrossed in some book or other, and usually it is only much later that you realize you have spent far too much time there and must dash off to keep some forgotten appointment---without buying a book, of course.This opportunity to escape the realities of everyday life is, I think, the main attraction of a bookshop. There are not many places where it is possible to do this. A music shop is very much like a bookshop. You can wander round such places to your heart’s content. If it is a good shop, no assistant will approach you with inevitable greeting: “Can I help you, sir?” You needn’t buy anything you don’t want. In a bookshop an assistant should remain in the background until you have finished browsing. Then, and only then, are his services necessary. Of course you may want to find out where a particular section is, but when he has led you there, the assistant should retire carefully and look as if he is not interested in selling a single book.You have to be careful not to be attracted by the variety of books in a bookshop. It is very easy to enter the shop looking for a book on ancient coins and to come out carrying a copy of the latest best-selling novel and perhaps a book about brass-rubbing---something that had only vaguely interested you up until then. This volume on the subject, however, happened to be so well illustrated and the part of the text you read proved so interesting that you just had to buy it. This sort of thing can be very dangerous. Apart from running up a huge account, you can waste a great deal of time wandering from section to section.71. What does “dust-jacket” in the first paragraph probably mean?A)The title of a book.B) A kind of clothes.C)Book cover full of dust.D)Protecting paper cover of a book.72. In the author’s opinion, what is the main attraction of a bookshop?A)You can spend much time in the bookshop.B)It has many books with attractive dust-jacket.C)It enables you to forget the realities of everyday life.D)You don’t have to go for unpleasant appointments.73. According to the passage, what will happen in a good bookshop?A)Nobody will take notice of you.B)You will feel as if you were in a music shop.C)You will find yourself undisturbed and satisfied with your own browsing.D)The assistant will greet and treat you in a very friendly way.74. The author thinks that the service of the bookshop assistant is needed ____.A)as soon as you enter the shopB)before you start your browsingC)only when you have finished your browsingD)after you have made your final decision75. Picking up books that vaguely interest you can be dangerous because ___.A)you may forget about the book you plan to buyB)it costs you too much money and timeC)it makes you break your appointmentD)you have to give up the best-selling bookPassage FourAll research to date on body image shows that women are much more critical of their appearance than men---much less likely to admire what they see in the mirror. Up to 8 out of 10 women are dissatisfied with their reflection, and more than half may see a distorted image.Men looking in the mirror are more likely to be either pleased with what they see or indifferent. Research shows that men generally have a much more positive body-image than women---if anything, they may tend to overestimate their attractiveness. Some men looking in the mirror may literally not see the flaws in their appearance.Why are women so much more self-critical than men? Because women are judged on their appearance more than men, and standards of female beauty are considerably bombarded with images of the “ideal” face. And constant exposure to idealized images of female beauty on TV, magazines and billboards makes exceptionalgood looks seem normal and anything short of perfection seem abnormal and ugly. It has been estimated that young women now see more images of outstandingly beautiful women in one day than our mothers saw through their entire adolescence. Also, most women are trying to achieve the impossible: standards of female beauty have in fact become progressively more unrealistic during the last century. In 1917, the physically perfect woman was about 5ft 4 in tall and weighed nearly 10 stone. Even 25 years ago, top models and beauty queens weighed only 8% less than the average woman. Now they weigh 23% less. The current media ideal for women is achievable by less than 5% of the female population---and that’s just in terms of weight and size. If you want the ideal shape, face, etc., it’s probably more like 1%.76. The main purpose of the passage is to _____.A)explain a phenomenonB)compare two factsC)make a suggestionD)strengthen a current theory77. The difference between men and women when they look into the mirror is that _____.A)women stay longer before the mirror than menB)women feel more comfortable about their appearance than menC)women, more than men, come away from the mirror feeling unsatisfiedD)women’s looks before the mirror appear more distorted than men’s78. The phrase “bombarded with” (Line 2, Para. 3) could best be replaced by ____.A)deniedB)doubtful ofC)very proud ofD)influenced by79. Which of the following can be inferred about the physically perfect woman in 1917?A)She was not very much different from the average woman.B)She was hardly achievable by the female population.C)She looked into the mirror more often than women today.D)She was regarded perfect only in terms of her face.80. Today’s perfect woman is achievable, in terms of every physical aspect, by ___ of the female population.A) 23% B) 8% C) 5% D) 1%Part IV. Cloze (5 points)Directions: There are 10 blanks for the following passage. Fill in the blanks and write your answer on the ANSWER SHEET.A foreigner’s first impression of the U.S. is likely to be that everyone is in a rush – often under pressure. City people always appear to be hurrying to get where they are going, ____81____seeking attention in a store, or ____82____ others as they try to complete their shopping. Racing through daytime meals is part of the pace of life in this country. Working time is considered ____83____.

This is because people value time highly, and they ____89____ someone else “wasting” it ____90____ a certain appropriate point.Part V.
