We chose the first. Up early, my husband and I and our three children couldn't wait to get started. We decided to walk along a lovely path named Bright Angel Trail.As we set out, I was shocked at how narrow the path was. And I couldn't help noticing that the other tourists weren't like us. They had heavy backpacks, water bottles, and hats. But as usual we were dressed. As the sun rose higher, Arizona' s famous heat seemed to roast us. There was no shade and our legs were aching. We decided to go back, with the girl on my back and the boys far behind. By the time we finally got back, our legs were like jelly.The next day, after we' d had a long rest and a good breakfast, we were ready for another view of the Canyon—by air. After our last walk, this would be the easiest thing in the world.We called to each other excitedly as the plane took off and circled around the Canyon. But the smiles on our faces disappeared as the pilot tossed(翻转)the plane around, pretending he was going to hit the ground. I shouted, "STOP, TAKE US BACK!" When we finally arrived back on land, once again our legs were like jelly. We hardly spoke as we drove back.As I said, there are three ways to view the Grand Canyon. We never tried the mules, but personally I' d suggest a fourth: buy yourself a good magazine like National Geographic. That way, you can see the Canyon, without fear or tiredness.41. Which of the following is true according to the second paragraph?A. They made a careful preparation before the trip.B. Bright Angel Trail was not as lovely as they expected.C. The children were more joyful than their parents.D. The summer heat prevented them from enjoying the view.42. The underlined expression "Our legs were like jelly" probably means __________ .A. we were dissatisfiedB. we were unhappyC. we were weakD. we were disappointed43. Which of the following best describes their Canyon trip by air?A. It made each of them tired.B. It was more comfortable.C. It turned out to be exciting.D. It proved to be frightening.44. We can infer from the passage that __________A. the writer was not serious when she made the suggestion.B. one needs to dress less when visiting the Grand Canyon.C. experiencing the Canyon on mules would be the best way.D. the whole family narrowly escaped from the air accident.BThe 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 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 this foolish idea that the treasures were "limitless"and "inexbaustible". Most of the citizens or earlier generations knew little or nothing about the 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 schoo l work; scientific 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; nobody had yet studied long-term climatic cycles in relation to proper land use; even the word "conservation" had nothing of the meaning that it has for us today.For the sake of ourselves and those who will come after us, w e must now set about repairing the mistakes of our forefathers. Conservation should, therefore, be made a part of everyone's daily life. To know about the water table(地下水位)in the ground is just as important to us as a knowledge of the basic arithmetic formulas. We need to know why all watersheds need the protection of plant life and why the running current of streams and river must be made to yield their full benefit to the soil before they finally escape to the sea. We need to be 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 man's 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 our goal to restore as much of the original beauty of nature as we can.45. The author' s attitude towards the present situation in the use of natural resources is __________.A. positiveB. neutralC. criticalD. suspicious46. According to the author, the greatest mistake of our forefathers was that __________.A. they had little or no sense of environmental protectionB. they had no idea about scientific forestryC. they did not know the importance of nature studyD. they had no idea of how to make good use of raw materials47. With a view to correcting the mistakes of our forefathers, the author suggests that __________.A. we plant more trees and make full use of the woodlandsB. we be taught environmental science, as well as the science of plantsC. we return to nature and not use any natural resources at allD. environmental education be directed toward everyone48. What does the author imply by saying "living space. . . above the earth. " (the underlined sentence in Paragraph 3)?A. Our living space on the earth is getting smaller and smaller in volume.B. We must create better living conditions for both birds and animals.C. We need to take some measures to protect space in volume.D. Our living space should be measured in cubic volume.CEducating girls quite possibly brings in a higher rate of return than any other investment available in the developing world. Women education may be an unusual field for economists, but increasing women' s contribution to development is actually as much an economic as a social issue. And economics provides guideposts that point to an explanation for why so many girls are deprived(被剥夺)of an education.Parents in low-income countries fail to invest in their daughters because they do not expect them to make an economic contribution to the family: girls grow up only to marry into somebody else’s family and bear children. Girls are thu s seen as less valuable than boys and are kept at home to do housework while their brothers are sent to school—the prophecy (预言) becomes self-fulfilling, trapping women in a bad circle of neglect.An educated mother, on the other hand, has greater earning abilities outside the home and faces an entirely different set of choices. She is likely to have fewer but healthier children and can insist on the development of all her children, ensuring that her daughters are given a fair chance. The education of her daughters then makes it much more likely that the next generation of girls, as well as of boys, will be educatedand healthy. The bad circle is thus transformed into a good one.Few will question that educating women has great social benefits. But it has enormous economic advantages as well. Most obviously, there is the direct effect of education on the wages of female workers. Wages rise by 10 to 20 percent for each additional year of schooling. Such big returns are impressive by the standard of other available investments, but they are just the beginning. Educating women also has a significant effect on health practices, including family planning.49. By saying “the prophecy becomes self-fulfilling. . . ” in Paragraph 2, the author means that __________.A. girls will be increasingly discontented with their life at homeB. girls will be capable of realizing their own dreamsC. girls will eventually find their goals in life beyond reachD. girls will turn out to be less valuable than boys50. The author believes that a bad circle can turn into a good circle when __________.A. women care more about educationB. a family has fewer but healthier childrenC. girls can gain equal access to educationD. parents can afford their daughters’ education51. What does the author say about women’ s education?A. It will bring in greater returns than other known investments.B. It is now given attention before anything else in many developing countries.C. It deserves greater attention than other social issues.D. It has aroused the interest of a growing number of economists.52. The passage mainly discusses __________.A. unequal treatment of boys and girls in developing countriesB. the economic and social benefits of educating womenC. the major contributions of educated women to societyD. the potential earning power of well-educated womenDHave you winterized your horse yet? Even though global warming may have made our climate more mild, many animals are still hibernating(冬眠).It’s too bad that humans can’t hibernate. In fact, as a species, we almost did.Apparently, at times in the past, peasants in France liked a semi-state of human hibernation. So writer Graham Robb, a British scholar who has studied the sleeping habits of the French peasants. As soon as the weather turned cold, people all over France shut themselves away and practiced the forgotten art of doing nothing at all for months on end.In line with this, Jeff Warren, a producer at CBC Radio’s The Current, tells us that the way we sl eep has changed fundamentally since the invention of artificial(人造的)lighting and the electric bulb.When historians began studying texts of the Middle Ages, they noticed something referred to as “first sleep”, which was not c larified, though. Now scientists are telling us our ancestors most likely slept in separate periods. The business of eight hours’ uninterrupted sleep is a modem invention. In the past, without the artificial light of the city to bathe in, humans went to sleep when it became dark and then woke themselves around midnight. The late night period was known as “The Watch”. It was when people actually kept watch against wild animals, although many of them simply moved around or visited family and neighhours.According to some sleep researchers, a short period of insomnia(失眠)at midnight is not a disorder. It is normal. Humans can experience another state of consciousness around their sleeping, which occurs in the brief period before we fall asleep or wake ourselves in the morning. This period can be an extraordinarily creative time for some people. The impressive inventor, Thomas Edison, used this state to hit upon many of his new ideas.Playing with your sleep rhythms can be adventurous, as anxiety may set in. Medical science doesn’t help much in this case. It offers us medicines for a full night’s continuous sleep, which sounds natural; however, according to Warren’s theory, it is really the opposite of what we need.53. The example of the French peasants shows the fact that __________.A. people might become lazy as a result of too much sleep.B. winter was a season for people to sleep for months on end.C. people tended to sleep more peacefully in cold weather.D. there were signs of hibernation in human sleeping habits.54. The late nigh t was called “The Watch” because it was a time for people __________.A. to set traps to catch animals.B. to wake up their family and neighbours.C. to guard against possible dangers.D. to remind others of the time.55. What does the author advise people to do?A. Follow their natural sleep rhythm.B. Consult a doctor if they can’t sleep.C. Sleep in the way animals do.D. Keep to the eight-hour sleep pattern.56. What is the author’s purpose in writing the passage?A. To give a prescription for insomnia.B. To throw new light on human sleep.C. To analyze the sleep pattern of modem people.D. To urge people to sleep less.ESomeday a stranger will read your e-mail without your permission or scan the Website you've visited, or perhaps someone will casually glance through your credit card purchases or cell phonebills to find out your shopping preferences or calling habits.In fact, it' s likely some of these things have already happened to you. Who would watch you without your permisson? It might be a spouse, a girlfriend, a marketing company, a boss, a cop or a criminal. Whoever it is, they will see you in a way you never intended to be seen—the 21st century equivalent of being caught naked.Psychologists tell us boundaries are healthy, and that it' s important to reveal yourself to friends, family and lovers in stages, at appropriate times. But few boundaries remain. The digital bread crumbs(碎屑)you leave everywhere make it easy for strangers to reconstruct who you are, where you are and what you like. In some cases, a simple Google search can reveal what you think. Like it or not, increasingly we live in a world where you simply cannot keep a secret.The key question is: Does that matter?For many Americans, the answer apparently is "No.When opinion polls ask Americans about privacy, most say they are concerned about losing it. A survery found an overwhelming pessimism about privacy, with 60 percent of respondents saying they feel their privacy is " slipping away, and that bothers me. "But people say one thing and do another. Only a tiny fraction of Americans change any behaviors in an effort to preserve their privacy. Few people turn down a discount at tollbooths(收费站)to avoid using the EZ -Pass system that can track automobile movements. And few turn down supermarket loyalty cards. Privacy economist A lessandro Acauisti has run a series of tests that reveal people will surrender personal information like Social Security numbers just to get their hands on a pitiful 50 - cents - off coupon(优惠卷).But privacy does matter—at least sometimes. It's like health: When you have it, you don't notice it. Only when it' s gone do you wish you' d done more to protect it.57. What does the author mean by saying the 21st century equivalent of being caught naked ?A. People tend to be more frank with each other in the information age.B. In the 21st century people try every means to look into others' secrets.C. People's personal information is easily accessed without their knowledge.D. Criminals are easily caught on the spot with advanced technology.58. What would psychologists advise on keeping good boundaries ?A. There is always something you shouldn't reveal.B. You should not always have good relationship with your friends and so on.C. All friends should open their hearts to each other.D. There should be fewer disputes and questions between friends.59. Why does the author say "we live in a world where you simply cannot keep a secret"?A. Modern society has finally evolved into an open society.B. Many search engines profit by revealing people's identities.C. There are always people who are curious about others' affairs.D. People leave traces around when using modern technology.60. According to the passage, privacy is like health in that __________.A. people will make every effort to keep it.B. people don't care it until they lose itC. is is something that can easily be lostD. its importance is rarely understood第二节:根据对话内容,从对话后的选项中选出能填入空白处的最佳选项,并在答题卡上将该项涂黑,选项中有两项为多余选项。
