When they were on the train, Kazrim told her, Im going to tell your parents Ill be looking after you well with all my life!” Galaxy was deeply moved. As soon as they had entered the

38、house, Galaxy introduced him to her parents. She said, This is Kazrim.” Just right after her speech, an unbelievable thing happened. Kazrim threw the gift away and held her in his arms tightly. He said, “YOU CAN TALK?” It was the same question that Galaxy wanted to ask, too. The four people were sho

39、cked all of a sudden. As a matter of fact, Kazrim always believed that Galaxy was a mute and he still fell in love with her deeply.71. How did Galaxy and Kazrim get to know each other? A.

It selves directly to bring about a rapid sale of goods at reasonable prices, so setting up a firm home market and so making it possible to provide for export at good prices. By d

45、rawing attention to new ideas it helps greatly to raise standards of living. By helping to increase demand it causes an increased need for labor, and is therefore a nice way to fight unemployment. It lowers the costs of many services: without advertisements your daily newspaper would cost four times

46、 as much, the price of your television program would need to be doubled, and travel by bus or subway would cost more. And perhaps most important of all, advertising provides a promise of reasonable value in the products and services you buy. Besides the fact that twenty-seven Acts of Parliament gove

47、rn the terms of advertising, no regular advertiser dare promote a product that fails to live up to the promise of his advertisements. He might fool some people for a little while through misleading advertising. He will not do so for long, for the public has the good sense not to buy the poor article

48、 more than once. If you see an article frequently advertised, it is the proof I know that the article does what is promised for it, and that it has good value.Advertising does more for the good of the public than any other force I can think of.There is one more point I feel I ought to touch on. Rece

49、ntly I heard a well-known television person declare that he was against advertising because it persuades rather than informs. He was telling us the real difference. Of course advertising tries to persuade. If its message were nothing but information, that would be difficult to get more people to buy

50、, for even a detail such as the choice of the color of a shirt is a bit persuasive-advertising would be so boring that no one would pay any attention. But perhaps that is what the well-known television person wants. 79. By the first sentence of the passage the writer means that . A. he is fairly fam

51、iliar with the cost of advertising B. everybody knows well that advertising is a waste of money C. advertising costs more money than everything else D. money spent on advertising is worth while 80. In the passage, which of the following is NOT included in the advantages of advertising? A. Getting gr

52、eater fame. B. Providing more jobs. C. Raising living standards. D. Reducing newspaper cost. 81. The author thinks that the well-known TV person is . A. quite right in passing his judgment on advertising B. interested in nothing but the buyers attention C. correct in telling the difference between p

53、ersuasion and information D. obviously unfair in his views on advertising 82. In the author opinion . A. advertising can seldom bring material benefit to man by providing information B. advertising informs people of new ideas rather than wins them over C. there is nothing wrong with advertising in p

54、ersuading the buyer D. the buyer is not interested in getting information from an advertisementDPicking tomatoes For as long as I can remember, Grandmas plentiful tomato garden has been a sign of summers end. Each September, just as the decreased heat of the sun suggests cooler days, Grandma request

55、s my help in her tomato garden. She convinces me she cannot pick tomatoes without my youthful eyes and quick mind. She says we need to examine each tomato and agree on its readiness for picking. While Grandmas request for my help in the tomato garden is always the same, her desire for my help seems

56、to increase each year. Grandma has eyes for finding even the tomatoes hidden by undergrowth and other tomatoes. I, however, just turn circles looking for the ones I think Grandma will like. I spot what looks like a ripe tomato, head in its direction, and then get sidetracked by another that appears

57、to be equally ripe. I usually end up watching Grandma and trying to stay out of her way, which seems the only way my eyes and mind ale useful. There we are, lost in the tomato vines（藤）. Grandmas eyes are always knowing, and they are no different in the vegetable garden. From afar she spots what look

58、s like a ripe tomato. As she walks toward the garden, she evaluates the tomato for a second time. but from a different angle. I already know it will end up in the basket with the pile of others Grandma has carefully chosen. However, Grandma acts as if she needs a final look to be sure. She calls me

59、to her side, kneels beside the vine while enjoying the warmth of the fading sunlight on her face, and grasps the tomato in her hand. She turns each round, red ball toward the sunlight before disconnecting it from thevine with a half-hearted smile. She then looks at me. I nod my head and smile. Grand

60、ma assumes I smile in agreement with her tomato selection. I know I smile, instead, at her. 83. Why does Grandma ask the author to go to the tomato garden with her? A. He can help pick more tomatoes. B. He can learn the hardship of labor. C. She enjoys staying with him while working. D. She tries to

61、 share the happiness of harvest with him. 84. The second paragraph shows that the author . A. is an inefficient tomato picker B. really has youthful eyes and quick mind C. has spent a lot of time gardening with Grandma D. is a naughty child trying to be out of Grandmas sight 85. In the last paragrap

62、h, the author smiled to Grandma because he . A. realizes her true intentions B. feels very happy to pick tomatoes for her C. confirms that her choice of tomato is great D. appreciates her skill in finding ripe tomatoes 86. What can we infer from the story? A. The grandchild will become more skillful

63、 at gardening than Grandma. B. Grandma will develop more patience in working with the grandchild. C. The grandchild will gradually become more independent of Grandma. D. Grandmas need for the grandchilds company will grow over time. E Age has its special advantage in America. And one of the more imp

64、ressive of them is the senior citizen discount. Anyone who has reached a certain agein some cases as low as 55is automatically entitled to plenty of price reductions at nearly every level of commercial life. Eligibility（资格）is determined not by ones need but by the date on ones birth certificate. Pra

65、ctically the discounts have become a routine part of many businesses-as common as color televisions in motel rooms and free coffee on airliners. People with gray hair often are given the discounts without even asking for them；yet, millions of Americans above age 60 are healthy and solvent（有支付能力的）. B

66、usinesses that would never dare offer discounts to college students or anyone under 30 freely offer them to older Americans. The practice is acceptable because of the widespread belief that “elderly” and “needy” are synonymous（同义的）. Perhaps that once was true, but today, to be sure, there is economi

67、c variety within the elderly, and most of them arent poor. It is impossible to determine the effect of the discounts on individual companies. For many firms, they are a stimulus to income. But in other cases the discounts are given at the expense, directly or indirectly, of younger Americans. Moreov

68、er, they directly annoy some politicians and scholars who consider it a coming conflict between the generations. Generational tensions are being fueled by continuing debate over Social Security benefits, which mostly involves a transfer of resources from the young to the old. Employment is another p

69、oint. Supported by laws and court decisions, more and more older Americans are refusing the retirement dinner in favor of staying on the job-thereby lessening employment and promotion opportunities for younger workers. Far from a kind of charity they once were, senior citizen discounts have become a

70、 powerful economic privilege（特权）to a group with millions of members who dont need them. It no longer makes sense to treat the elderly as a single group whose economic needs deserve priority over those of others. Senior citizen discounts only enrich the myth that older people cant take care of themse

71、lves and need special treatment；and they threaten the creation of a new myth, that the elderly ale ungrateful and taking for themselves at the expense of children and other age groups. Senior citizen discounts are the heart of the very thing older Americans are fighting againstdiscrimination by age.

72、 87. We learn from the first paragraph that . A. offering senior citizen discounts has become routine commercial practice B. senior citizen discounts have enabled many old people to live a good life C. giving senior citizen discounts has increased the market for the elderly D. senior citizens have t

73、o show their birth certificates to get a discount 88. The reason to give the senior citizen discount is that . A. the elderly need humane help from society B. businesses should do something for society in return C. old people are entitled to special treatment for their contribution to society D. the

74、 senior discounts can make up for the lack of the Social Security system 89. What does the author think of the Social Security system? A. It encourages elderly people to retire in time. B. It opens up broad career chances for young people. C. It benefits the old at the expense of the young. D. It sh

75、ould be strengthened by laws and court decisions. 90. What does the author mainly argue in the passage? A. Senior citizens should fight hard against age discrimination. B. The elderly are selfish and taking senior discounts for granted. C. Senior citizen discounts may well be a type of age discrimin

76、ation. D. Discount should be given to the economic needs of senior citizens. 第二卷（两部分，共50分）第四部分：上机阅读（共10分）第五部分：阅读信息还原（共5小题，每小题1分，满分5分） As you grow rapidly through your teenage years, you will experience a lot of changes.
