7、se we all have a memory. Our memory tells us who we are. Our memory helps us to make use in the present of what we have learnt in the past. In fact we have different types of memory. For example, our visual memory helps us recall facts and places. Some people have such a strong visual memory that th

8、ey can remember exactly what they have seen, for example, pages of a book, as a complete picture. Our verbal(言语的) memory helps us remember words and figures we may have heard but not seen or written: Items of a shopping list, a chemical formula, dates, or a recipe. With our emotional(情感的)memory, we

9、recall situations or places where we had; strong feelings, perhaps of happiness or unhappiness. We also have special memories for smell, taste, touch and sound, and for performing physical movements. We have two ways of storing any of these memories. Our short-term memory stores items for up to thir

10、ty secondsenough to remember a telephone number while we dial. Our long-term memory, on the other hand, may store items for a lifetime. Older people in fact have a much biter long-term memory than short-term. They may forget what they have done only a few hours ago, but have the clearest remembrance

11、(记忆) of when they were very young. Psychologists tell us that we only remember a few facts about our past, and that we invent the rest. It is as though we remember only the outline of a story. We then make up the details. We often do this in the way we want to remember them, usually so that we appea

12、r as the heroes of our own past, or maybe victims needing sympathy (同情).（分数：7.00）(1).Visual memory helps us recall a place we have been to.（分数：1.00）A.RightB.WrongC.Not mentioned(2).Visual memory may be used when we read a story.（分数：1.00）A.RightB.WrongC.Not mentioned(3).Verbal memory helps us read wo

Transport is one of the aids to trade. By moving goods from places where they are plentiful to places whe

15、re they are scarce, transport adds to their value. The more easily goods can be brought over the distance that separates producer and consumer, the better for trade. When there were no railways, no good roads, no canals, and only small sailing ships, trade was on a small scale. 2. The great advances

16、 made in transport during the last two hundred years were accompanied by a big increase in trade. Bigger and faster ships enabled a trade in meat to develop between Britain and New Zealand, for instance. Quicker transport makes possible mass-production and big business, drawing supplies from, and se

17、lling goods to, all parts of the globe. Big factories could not exist without transport to carry the large number of workers they need to and from their homes. Big city stores could not have developed unless customers could travel easily from the suburbs and goods were delivered to their homes. Big

18、cities could not survive unless food could be brought from a distance. 3. Transport also prevents waste. Much of the fish landed at the ports would be wasted if it could not be taken quickly to inland towns. Transport has given us a much greater variety of foods and goods since we no longer have to

19、live on what is produced locally. Foods which at one time could be obtained only during a part of the year can now be obtained all through the year. Transport has raised the standard of living. 4. By moving fuel, raw materials, and even power, for example, through electric cables, transport has led

20、to the establishment of industries and trade in areas where they would have been impossible before. Districts and countries can concentrate on making things which they can do better and more cheaply than others and can then exchange them with one another. The cheaper and quicker transport becomes, t

21、he longer the distance over which goods can profitably be carried. Countries with poor transport have a lower standard of living. 5. Commerce requires not only the moving of goods and people but also the carrying of messages and information. Means of communication, like telephones, cables and radio,

22、 send information about prices, supplies, and changing conditions in different parts of the world. In this way, advanced communication systems also help to develop trade.（分数：8.00）(1).Paragraph 2 1 A. Higher Living Standard B. Importance of Transport in Trade C. Various Means of Transport D.

26、cessary. We may be able to hang on to most of that youthful vigor even if we don“t start to diet until old age. Stephen Spindler and his colleagues from the University of California at Riverside have found that some of an elderly mouse“s liver genes can be made to behave as they did when the mouse w

27、as young simply by limiting its food for four weeks. The genetic rejuvenation won“t reverse other damage caused by time for the mouse, but could help its liver metabolize drugs or get rid of toxins. Spindler“s team fed three mice a normal diet for their whole lives, and fed another three on half-rat

28、ions. Three more mice were switched from the normal diet to half-feed for a month when they were 34 months oldequivalent to about 70 human years. The researchers checked the activity of 11,000 genes from the mouse livers, and found that 46 changed with age in the normally fed mice. The changes were

29、associated with things like inflammation and free radical productionprobably bad news for mouse health. In the mice that had dieted all their lives, 27 of those 46 genes continued to behave like young genes. But the most surprising finding was that the mice that only started dieting in old age also

30、benefited from 70 percent of these gene changes. “This is the first indication that these effects kick in pretty quickly,“ says Huber Warner from the National Institute on Aging near Washington D. C. No one yet knows if calorie restriction works in people as it does in mice, but Spindler is hopeful.

31、 “There“s attracting and tempting evidence out there that it will work,“ he says. If it does work in people, there might be good reasons for rejuvenating the liver. As we get older, our bodies are less efficient at metabolizing drugs, for example. A brief period of time of dieting, says Spindler, co

32、uld be enough to make sure a drug is effective. But Spindler isn“t sure the trade-off is worth it. “The mice get less disease, they live longer, but they“re hungry,“ he says. “Even seeing what a diet does, it“s still hard to go to a restaurant and say: “I can only eat half of that.“ Spindler hopes w

33、e soon won“t need to diet at all. His company, Lifespan Genetics in California, is looking for drugs that have the effects of calorie restriction.（分数：15.00）(1).According to the passage, which of the following is NOT true?（分数：3.00）A.Eating less than usual might make us live longer.B.If we go on a die

34、t when old, we may keep healthy.C.Dieting might not be needed.D.We have to begin dieting since childhood.(2).Why does the author mention an elderly mouse in paragraph 2?（分数：3.00）A.To describe the influence of old age on mice.B.To illustrate the effect of meager food on mice.C.To tell us how mice“s l

35、iver genes behave.D.To inform us of the process of metabolizing drugs.(3).What can be inferred about completely normally fed mice mentioned in the passage?（分数：3.00）A.They will not experience free radical production.B.They will experience more genetic rejuvenation in their lifetime.C.They have more o

36、ld liver genes to behave like young genes.D.They are more likely to suffer from inflammation.(4).According to the author, which of the following most interested the researchers?（分数：3.00）A.The mice that started dieting in old age.B.27 of those 46 old genes that continued to behave like young genes.C.

37、Calorie restriction that works in people.D.Dieting that makes sure a drug is effective.(5).According to the last two paragraphs, Spindler believes that（分数：3.00）A.drugs do not have the effects of calorie restrictionB.dieting is not a good method to give us health and long lifeC.seeing the effect of a

38、 diet, people will like to eat less than normalD.calorie restriction is very important to young people六、第二篇(总题数：1，分数：15.00)Long Bus RideLong bus rides are like television shows. They have a beginning, a middle, and an endwith commercials thrown in every three or four minutes. The commercials are una

39、voidable. They happen whether you want them or not. Every couple of minutes a billboard (广告牌) glides by outside the bus window. “Buy Super Clean Toothpaste.“ “Drink Good“n Wet Root Beer.“ “Fill up with Pacific Gas.“ Only if you sleep, which is equal to turning the television set off, are you spared

40、the unending cry of “You Need It! Buy It Now!“ The beginning of the ride is comfortable and somewhat exciting, even if you“ve traveled that way before. Usually some things have changednew houses, new buildings, sometimes even a new road. The bus driver has a style of driving and it“s fun to try to f

41、igure it out the first hour or so. If the driver is particularly reckless(鲁莽的) or daring, the ride can be as thrilling as a suspense story. Will the driver pass the truck in time? Will the driver move into the right or the left-hand lane? After a while, of course, the excitement dies down. Sleeping

42、for a while helps pass the middle hours of the ride. Food always makes bus rides more interesting. But you“ve got to be careful of what kind of food you eat. Too much salty food can make you very thirsty between stops. The end of the ride is somewhat like the beginning. You know it will soon be over

43、 and there“s a kind of expectation and excitement in that. The seat, of course, has become harder as the hours have passed. By now you“ve sat with your legs crossed, with your hands crossed behind your head. The end comes just at the right time. There are just no more ways to sit.（分数：15.00）(1).Accor

44、ding to the passage, what do the passengers usually see when they are on a long bus trip?（分数：3.00）A.buses on the road.B.films on television.C.advertisements on the board.D.gas stations.(2).What is the purpose of this passage?（分数：3.00）A.To give the writer“s opinion about long bus trips.B.To persuade

45、you to take a long bus trip.C.To explain how bus trips and television shows differ.D.To describe the billboards along the road.(3).The writer of this passage would probably favor _.（分数：3.00）A.bus drivers who weren“t recklessB.driving aloneC.a television set on the busD.no billboards along the road(4

46、).The writer feels long bus rides are like TV shows because _.（分数：3.00）A.the commercials both on TV shows and on billboards along the road are funB.they both have a beginning, a middle, and an end, with commercials in betweenC.the drivers are always reckless on TV shows just as they are on busesD.bo

47、th traveling and watching TV are not exciting(5).The writer thinks that the end of the ride is somewhat like the beginning because both are _.（分数：3.00）A.excitingB.comfortableC.tiringD.boring七、第三篇(总题数：1，分数：15.00)Renewable Energy SourcesToday petroleum(石油) provides around 40% of the world“s energy nee

48、ds, mostly fuelling automobiles. Coal is still used, mostly in power stations, to cover one-quarter of our energy needs, but it is the least efficient, unhealthiest and most environmentally damaging fossil fuel(矿物燃料). Natural gas reserves could fill some of the gap from oil, but reserves of that wil

49、l not last into the 22nd century either. Most experts predict we will exhaust easily accessible reserves within 50 years. Less-polluting renewable energy sources offer a more practical long-term energy solution. “Renewable“ refers to the fact that these resources are not used faster than they can be replaced. Hydroelectric(水力发电的)power is now the most common form of renewable energy, supplying around 20% of world electricity. China“s Three Gorges Dam is the largest ever. At five times the size of the U.S.“s Hoover Dam, its 26 turbines(涡轮机) will generate the equivalent ener
