For questions 1-7, mark：Y (for YES) if the statement agrees with the information given in the passage;N (for NO) if the statement contradict

3、s the information given in the passage;NG (for NOT GIVEN) if the information is not given in the passage.2 You hear the same complaint all the time as people get older: My memory is terrible. Is it all in the mind, or do real changes take place in the brain with age to justify such grumbling(抱怨)? Th

4、e depressing answer is that the brains cells, the neurons, die and decline in efficiency with age.Professor Arthur Shimamura, of the University of California at Berkeley, says there are three main ways in which mental function changes. The first is mental speed, for example how quickly you can react

5、 to fast-moving incidents on the road. Drivers in their late teens react quickly but tend to drive too fast, while the over sixties are more cautious but react more slowly. The near-inevitable slowing with age also partly explains why soccer players are seen as old in their thirties, while golf prof

6、essionals are still in their prime at that age. This type of mental slowing results from a reduction in the efficiency with which the brains neurons work.The fact that adults find it harder to learn musical instruments than children points to a second type of mental loss with agea reduction in learn

7、ing capacity. The parts of the brain known as the temporal lobes control new learning, and are particularly vulnerable to the effects of aging. This means that, as we get older, we take longer to learn a new language, are slower to master new routines and technologies at work, and we have to rely mo

8、re on diaries and other mental aids.Working memory is the third brain system which is vulnerable to the effects of aging. Working memory is the brains blackboard, where we juggle from moment to moment the things we have to keep in mind when solving problems, planning tasks and generally organizing o

9、ur day-to-day life. Absent-mindedness occurs at all ages because of imperfections in the working memory systemso, for instance, you may continually lose your glasses, or find yourself walking into a room of your house only to find that you cannot remember what you came for.Such absent-mindedness ten

10、ds to creep up on us as we age and occurs because our plans and intentions, which are chalked up on the mental blackboard, are easily wiped out by stray thoughts and other distractions. Stress and preoccupation can also cause such absent-mindedness, in addition to age-related changes in the brain. T

11、he frontal lobes of the brainlocated behind the forehead and above the eyes are where the working memory system is located. Like the temporal lobes, which handle new learning, the frontal lobes are more vulnerable to the aging process than other parts of the brain.The news, however, is not all bleak

12、. Although neurons reduce in number with age, the remaining neurons send out new and longer connecting fibres(dendrites) to maintain connections and allow us to function reasonably well with only relatively small drops in ability.This and other evidence suggests that the principle use it or lose it

13、might apply to the aging brain. Professor Shimamura studied a group of university professors who were still intellectually active, and compared their performance on neuropsychological tests with that of others of their age group, as well as with younger people. He found that on several tests of memo

14、ry, the mentally active professors in their sixties and early Seventies were superior to their contemporaries, and as good as the younger people.Research on animals provides even stronger evidence of the effects of stimulation on the brain structure. Professor Bryan Kolb, of the University of Lethbr

15、idge in Canada, has shown that animals kept in stimulating environments show sprouting(生长) and lengthening of the connecting nerve fibres in their brains, in comparison With animals kept in unstimulating environments.The beneficial effects of continued mental activity are shown by the fact that olde

16、r contestants in quiz shows are just as fast and accurate in responding to general knowledge questions as younger competitors, suggesting that at least part of their intellectual apparatus is spared the effects of aging because of practice and skill.Such findings lead to the intriguing possibility o

17、f mental fitness training to accompany jogging and workouts for the health conscious. Research in Stockholm by Professor Lars Backman and his colleague has shown that older people can be trained to use their memory better, with the effects of this training lasting several years.Just as people go bal

18、d or grey at different rates, so the same is true for their mental faculties. Why this should be the case for memory and other mental functions is not yet clear, If Professor Shimamura is fight, then the degree to which people use and stretch their mental faculties may also have a role to play.2 The

You are required to select one word for each blank from a list of choices given in a word bank following the passage. Read the passage through carefully before making your choices. Each

36、choice in the bank is identified by a letter. Please mark the corresponding letter for each item with a single line through the center. You may not use any of the words in the bank more than once.36 When Roberto Feliz came to the USA from the Dominican Republic, he knew only a few words of English.

Each passag

42、e 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.46 The word conservation has a thrifty(节俭) meaning. To conserve is to save and protect, to leave what we ourselves enjoy in such good condition

43、 that others may also share the enjoyment. Our forefathers had no idea that human population would increase faster than the supplies of raw materials; most of them, even until very recently, had the foolish idea that the treasures were “limitless“ and “inexhaustible“. Most of the citizens of earlier

44、 generations knew little or nothing about complicated and delicate system that runs all through nature, and which means that, as in a living body, an unhealthy condition of one part will sooner or later be harmful to all the others.Fifty years ago nature study was not part of the school work; scient

45、ific forestry was a new idea; timber was still cheap because it could be brought in any quantity from distant woodlands; soil destruction and river floods were not national problems; people had hardly studied long-term climatic cycles in relation to proper land uses even the word “conservation“ had

46、nothing of the meaning that it has for us today.For the sake of ourselves and those who will come after us, we must now set about repairing the mistakes of our forefathers. Conservation should therefore, be made a part of everyones daily life. To know about the water table (水位) in the ground is just

47、 as important to us as a knowledge of the basic arithmetic formulas. We need to know why all watersheds (分水岭) need the protection of plant life and why the running currents of streams and rivers must be made to yield their full benefit to the soil before they finally escape to the sea. We need to be

48、 taught the duty of planting trees as well as of cutting them. We need to know the importance of big, mature trees, because living space for most of mans fellow creatures on this planet is figured not only in square measure of surface but also in cubic volume above the earth. In brief, it should be

49、our goal to restore as much of the original beauty of nature as we can.47 The authors attitude towards the current situation in the exploitation of natural resources is_.（A）positive（B） natural（C） suspicious（D）critical48 According to the author, the greatest mistake of our forefathers was that_.（A）they had no idea about scie
