A) makes B) to make C) made D) make 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. Passage One When one looks back upon the fifteen hundred years that are the life span of the English language, he should be able to notice a number of significant truths. The history of our language has always been a history of constant change—at times a slow, almost imperceptible change, at other times a violent collision between two languages. Our language has always been a living growing organism, it has never been static. Another significant truth that emerges from such a study is that language at all times has been the possession not of one class or group but of many. At one extreme it has been the property of the common, ignorant folk, who have used it in the daily business of their living, much as they have used their animals or the kitchen pots and pans. At the other extreme it has been the treasure of those who have respected it as an instrument and a sign of civilization, and who have struggled by writing it down to give it some permanence, order, dignity, and if possible, a little beauty. As we consider our changing language, we should note here two developments that are of special and immediate importance to us. One is that since the time of the Anglo-Saxons there has been an almost complete reversal of the different devices for showing the relationship of words in a sentence. Anglo-Saxon (old English) was a language of many inflections. Modern English has few inflections. We must now depend largely on word order and function words to convey the meanings that the older language did by means of changes in the forms of words. Function words, you should understand, are words such as prepositions, conjunctions, and a few others that are used primarily to show relationships among other words. A few inflections, however, have survived. And when some word inflections come into conflict with word order, there may be trouble for the users of the language, as we shall see later when we turn our attention to such maters as WHO or WHOM and ME or I. The second fact we must consider is that as language itself changes, our attitudes toward language forms change also. The eighteenth century, for example, produced from various sources a tendency to fix the language into patterns not always set in and grew, until at the present time there is a strong tendency to restudy and re-evaluate language practices in terms of the ways in which people speak and write. 51. In contrast to the earlier linguists, modern linguists tend to . A) attempt to continue the standardization of the language B) evaluate language practices in terms of current speech rather than standards or proper patterns C) be more concerned about the improvement of the language than its analysis or history D) be more aware of the rules of the language usage 52. Choose the appropriate meaning for the word “inflection” used in line 4 of paragraph 2. A) Changes in the forms of words. B) Changes in sentence structures. C) Changes in spelling rules. D) Words that have similar meanings. 53. Which of the following statements is not mentioned in the passage? A) It is generally believed that the year 1500 can be set as the beginning of the modern English language. B) Some other languages had great influence on the English language at some stages of its development. C) The English language has been and still in a state of relatively constant change

2006—2007 下二级单元测试 6 D) Many classes or groups have contributed to the development of the English language. 54. The author of these paragraphs is probably a (an) . A) historian B) philosopher C) anthropologist D) linguist 55. Which of the following can be best used as the title of the passage? A) The history of the English language. B) Our changing attitude towards the English language. C) Our changing language. D) Some characteristics of modern English. Passage Two You would like to take good photographs of real-life situations but you have few ideas for pictures. I suggest you look around you. The everyday world is full of scenes being played by an ever-changing group of actors. You probably passed a dozen picture situations without noticing on your way to work this morning. The realistic approach to photograph has been perfected in the past by such maters as Henri Cartier-Bresson and Bill Brandt. But while you can learn a great deal from looking at the work of others, any success you can hope to achieve in this field has to come from developing an individual approach. The main requirement for any photographer has little to do with technical matters. You must develop an awareness of the world around you and the people who live in it, and you should learn to notice when a situation may develop to a point where you will be able to take a good picture. Those who have reached this happy state will be prepared when that moment comes, and will simply raise their camera quickly and shoot. Others who are not so aware will be struggling with camera cases and lens caps（镜头盖）. Film manufactures must be delighted at the thought of the inexperienced photographer setting out in search of the right situation and the right moment. Many miles of costly material have passed through thousands of cameras as this endless search continues. But although a lot of this waste must be put down to inexperience, you'll find that even the professionals have to use a lot of film when they are out shooting. Not every shot is going to be a winner. If you look at the work of even the best photographers, you'll notice dozens of pictures have had to be taken only because they lead up to the successful shot of a situation that the photographer has obviously been observing through the lens. You may find that you have taken one or two pictures after the right moment has passed as well. There is seldom more than one shot which stands out. There is just one point where it all comes together, and you often have to waste film to catch that precious moment. 56. According to the passage, one can become a better real-life photographer by _____. A. watching other photographers at work B. learning about famous photographers C. just taking a great many photographs D. developing skills and ideas for yourself 57. The writer thinks that a photographer is required to _____. A. go out and search for unusual situations B. be highly skilled in camera techniques C. be able to tell when a good situation might come D. have a camera which is easy and quick to use 58. Most likely, to catch the right moment, one must _____. A. take pictures without too much preparation B. take a whole series of similar pictures C. take great care to set up the situation D. take one picture just at the right moment 59. Which of the following is TRUE?

2006—2007 下二级单元测试 7 A. The waste of film in photography is essential to the production of good pictures. B. Film manufacturers usually enjoy pictures by inexperienced photographers. C. Only amateur photographers waste film in taking pictures. D. The waste of film, which is the result of poor choice of subject, is expensive and unnecessary. 60. The passage is _____. A. part of a book of camera instruction B. an advertisement for film C. a history of photography D. an introduction to photography Passage Three The predictability of our mortality rates is something that has long puzzled social scientists. After all, there is no natural reason why 2,500 people should accidentally shoot themselves each year or why 7,000 should drown or 55,000 die in their cars. No one establishes a quota for each type of death. It just happens that they follow a consistent pattern year after year. A few years ago a Canadian psychologist named Gerald Wilde became interested in this phenomenon. He noticed that mortality rates for violent and accidental deaths throughout the Western world have remained oddly static throughout the whole of the century, despite all the technological advances and increases in safety standards that have happened in that time. Wilde developed an intriguing theory called “risk homeostasis”. According to this theory, people instinctively live with a certain level of risk. When something is made safer, people will get around the measure in some way to reassert the original level of danger. If, for instance, they are required to wear seat belts, they will feel safer and thus will drive a little faster and a little more recklessly, thereby statistically canceling out the benefits that the seat belt confers. Other studies have shown that where an intersection is made safer, the accident rate invariably falls there but rises to a compensating level elsewhere along the same stretch of road. It appears, then, that we have an innate need for danger. In all events, it is becoming clearer and clearer to scientists that the factors influencing our lifespan are far more subtle and complex than had been previously thought. It now appears that if you wish to live a long life, it isn’t simply a matter of adhering to certain precautions … eating the right foods, not smoking, driving with care. You must also have the right attitude. Scientists at the Duke University Medical Center made a 15-year study of 500 persons personalities and found, somewhat to their surprise, that people with a suspicious or mistrustful nature die prematurely far more often than people with a sunny disposition. Looking on the bright side, it seems, can add years to your life span. 61. What social scientists have long felt puzzled about is why . A) the mortality rate can not be predicted B) the death toll remained stable year after year C) a quota for each type of death has not come into being D) people lost their lives every year for this or that reason 62. In his research, Gerald Wilde finds that technological advances and increases in safety standards . A) have helped solve the problem of so high death rate B) have oddly accounted for mortality rates in the past century C) have reduced mortality rates for violent and accidental deaths D) have achieved no effect in bringing down the number of deaths

A) our innate desire for risk B) our fast and reckless driving C) our ignorance of seat belt benefits D) our instinctive interest in speeding 64. By saying “…statistically canceling out the benefits that the seat belt confers” (Para. 2),the author means .

Which of the following may contribute to a longer life span? A) Showing adequate trust instead of suspicion of others B) Eating the food low in fat and driving with great care C) Cultivating an optimistic personality and never losing heart D) Looking on the bright side and developing a balanced level of risk Passage Four We all know that DNA has the ability to identify individuals but, because it is inherited, there are also regions of the DNA strand which can relate an individual to his or her family (immediate and extended), tribal group and even an entire population. Molecular Genealogy (宗谱学) can use this unique identification provided by the genetic markers to link people together into family trees. Pedigrees (家谱) based on such genetic markers can mean a breakthrough for family trees where information is incomplete or missing due to adoption, illegitimacy or lack of records. There are many communities and populations which have lost precious records due to tragic events such as the fire in the Irish courts during Civil War in 1921 or American slaves for whom many records were never kept in the first place. The main objective of the Molecular Genealogy Research Group is to build a database containing over 100,000 DNA samples from individuals all over the world. These individuals will have provided a pedigree chart of at least four generations and a small blood sample. Once the database has enough samples to represent the world genetic make-up, it will eventually help in solving many issues regarding genealogies that could not be done by relying only on traditional written records. Theoretically, any individual will someday be able to trace his or her family origins through this database. In the meantime, as the database is being created, molecular genealogy can already verify possible or suspected relationships between individuals. “For example, if two men sharing the same last name believe that they are related, but no written record proves this relationship, we can verify this possibility by collecting a sample of DNA from both and looking for common markers (in this case we can look primarily at the Y chromosome (染色体),” explains Ugo A.
