2. Passage Eight Wisdom teeth are normally the last teeth to appear. This usually happens when people are in their late teen years or early twenties—in other words， when they are older and wiser. Wisdom teeth are chewing teeth， at the back of the mouth. They can grow into place normally and never cause a problem. But often there is not enough room for them in the mouth. They might crowd other teeth. Sometimes they even push sideways through the gums (牙床). An impacted wisdom tooth is one that fails to completely rise through the gum—the term is 【erupt】. Wisdom teeth that only partially erupt can leave space for bacteria to enter around the tooth. Infection is a risk in these cases. Wisdom teeth that are not well in place and become impacted are often removed. People should have the placement of their wisdom teeth examined between the ages of sixteen and twenty. X-rays can show wisdom teeth that are below the gums. The American Dental Association says removal is generally advised when wisdom teeth only partly break through the gums. Removal is also advised if there is a chance that poorly placed wisdom teeth will damage other teeth. And removal is called for in cases where fluid collects around a wisdom tooth that is partly or fully below the gum. But why do we have wisdom teeth if we often need to get them removed? One theory has to do with our diets. Scientists say the diet of prehistoric humans probably required more chewing teeth. Life was probably alittle rougher on the teeth back then， too. So it was good to have extras. The American Association of Oral and Maxillofacial (上颌面的) Surgeons says young adults are the best candidates for wisdom teeth removal. The group says older patients may be at greater risk for disease in the tissue surrounding the teeth. After surgery， there can be swelling of the gums and face and some pain. Both can be treated with cold wraps and medication (药物治疗). The term “erupt” in this passage probably means ( ) .

A. a tooth suddenly appears

B. a tooth rises through the gum

C. a wisdom tooth suddenly causes a problem

D. a wisdom tooth fails to rise completely

4. Passage Nineteen A 3-year-old boy who was lost in the woods for two days is now safe at home. But Casey Hathaway told his rescuers that he was not alone in the rainy， freezing cold woods. He said he was with a friend——abear. The child went missing on January 22 while playing with friends at his grandmother’s house in the southern state of North Carolina. When the other children returned to the house and Casey did not， the family searched the area for almost an hour before calling the police. Police formed a search and rescue team to look for the young boy in the nearby woods. But two days went by and still——no Casey. The woods of North Carolina are home to many black bears， like this one. It seems one of them helped a little boy while he was lost in the woods. Then on January 24， someone called the police saying they heard a child crying in the woods. Police followed up on the information and found Casey at about 9:30 that night. They pulled him out of some briar (荆棘). He was in good health. Police Officer Chip Hughes said that Casey did not say how he was able to survive in the woods for two days in the cloud， rainy weather， but that “he did say he had a friend in the woods that was a bear that was with him. ” Hundreds of people helped in the search and rescue efforts， including some 600 volunteers， federal police and members of the military. Hughes told reporters that at no point did he think Casey had been kidnapped (绑架). Doctors at Carolina East Medical Center treated Casey for minor injuries. He was then released to his family on January 25 .When found in the woods， Casey was ( ) .

A. playing with a bear

B. badly injured by a bear

C. hiding in some briar

D. in good condition

4. Passage Seventeen No one knows how man learned to make words. Perhaps he began by making sounds like those made by animals. Perhaps he grunted like a pig when he lifted something heavy. Perhaps he made sounds like those he heard all round him——water splashing， bees humming， a stone falling to the ground. Somehow， he learned to make words. As the centuries went by， he made more and more new words. This is what we mean by language. People living in different countries made different kinds of words. Today there are about fifteen hundred different languages in the world. Each contains many thousands of words. A very large English dictionary， for example， contains four or five hundred thousand words. But we do not need all these. Only a few thousand words are used in everyday life. The words you know are called your vocabulary. You should try to make your vocabulary bigger. You’re supposed to read as many books as you can. There are plenty of books written in easy English for you to read. You will enjoy them. When you meet a new word， you should find it in your dictionary. Your dictionary is your most useful book. Man ( ) to make sounds.

A. used words

B. followed many things in nature

C. lifted heavy things

D. grunted like a pig

3. Passage Twenty-Three Washington Irving was America’s first man of letters to be known internationally. His works were received enthusiastically both in England and in the United States. He was， in fact， one of the most successful writers of his time in the country， and at the same time winning the admiration of fellow writers like Scott in Britain and Poe and Hawthorne in the United States. The respect in which he was held was partly owing to the man himself， with his warm friendliness， his good sense， his urbanity， his gay spirits， his artistic integrity， his love of both the Old World and the New. Thackery described Irving as “a gentleman， who， though himself born in no very high sphere， was most finished， polished， witty; socially the equal of the most refined Europeans. ” In England he was granted an honorary degree from Oxford—an unusual honor for a citizen of a young， uncultured nation—and he received the medal of the Royal Society of Literature. America made him ambassador to Spain. Irving’s background provides little to explain his literary achievements. A gifted but delicate child， he had little schooling. He studied law， but without zeal， and never did practice seriously. He was immune to his strict Presbyterian home environment， frequenting both social gatherings and the theatre. Which of the following best describes the effect of Irving’s Presbyterian background on his life?

A. It fostered his love for the theater.

B. It developed his skill in business.

C. It prompted his interest in law.

D. It had almost no effect on his life.

50. This project is said right now and so far everything is going on quite smoothly.

4. Passage Twenty-One What will man be like in the future—in 5，000 or even 50，000 years from now? We can only make guesses， of course， but we can be sure that he will be different from what he is today. For man is slowly changing all the time. Let us take an obvious example. Man， even five hundred years ago， was shorter than he is today. Now， on average， men are about three inches taller. Five hundred years is relatively short period of time， so we may assume that man will continue to grow taller. Again， in the modern world we use our brains a great deal. Even so， we still make use of only about 20% of the brain’s capacity. As time goes on， however， we shall have to use our brains more and more， and eventually we shall need larger ones. This is likely to bring about a physical change to the head， in particular the forehead will grow larger. Nowadays our eyes are in constant use. In fact， we use them so much that very often they become weaker and we have to wear glasses. But over very long period of time it is likely that man’s eyes will grow stronger. On the other hand， we tend to make less use of our arms and legs. These， as a result， are likely to grow weaker. At the same time， however， our fingers will grow more sensitive because they are used a great deal in modern life. But what about hair? It will probably disappear from the body altogether in course of time because it does not serve a useful purpose any longer. In the future， then， both sexes are likely to be bald. Perhaps all this gives the impression that future man will not be a very attractive creature to look at. This may well be true. All the same， in spite of all these changes， future man will still have a lot in common with us. He will still be a human being， with thoughts and emotions similar to our own.Future man will probably ( ) .

A. have smaller eyes

B. see better

C. have larger eyes

D. wear better glasses

2. Passage Twenty-Six Today just as technology changed the face of industry， farmers have undergone an “agricultural revolution” . On the farm of today， machines provide all the power. One of the most important benefits will be the farm computer. A few forward-looking farmers are already using computers to help them run their farms more efficiently. The computers help them keep more accurate records， so they can make better decisions on what crops to plant， how much livestock to buy， when to sell their products， and how much profit they can expect. Many computer companies have been developing special computer programs just for farmers. Programs are being written for hog (猪) producers， grain farmers， potato farmers， and dairy farmers. In the future， farmers will be able to purchase computer programs made to their needs. Because of the growing importance of computers on the farm， students at agricultural colleges are required to take computer classes in addition to their normal agricultural courses. There can be no doubt that farmers will rely on computers even more in the future. While the old-time farm depended on horse power， and modern farms depend on machine power， farms of the future will depend on computer power. Another technological advance which is still in the experimental stage is the robot， a real “mechanized hired hand” that will be able to move and， in some ways， think like a human being. Agricultural engineers believe that computer-aided robots will make startling changes in farming before the end of the century. Unlike farmers of the present， farmers of the future will find that many day-to-day tasks will be done for them. Scientists are now developing robots that will be able to shear (修剪) sheep， drive tractors， and harvest fruit. Even complex jobs will be done by robots. For example， in order to milk their cows， farmers must first drive them into the special barn (畜棚)， then connect them to the milking machines， watch the machines， and disconnect them when they are finished. In the future， this will all be done by robots. In addition， when the milking is completed， the robots will automatically check to make sure that the milk is pure. The complete mobilization of the farm is far in the future， but engineers expect that some robots will be used before long. According to the passage， computers can not help farmers decide ( ) .

A. how much money they can earn from their products
