I didn’t think there would be any difficulty in getting it mended, as there was a lot of antique〔古董〕shops near my home. So I left home one morning, carrying the chair with me. I went into the first shop, expecting a friendly reception. I was quite wrong. The man didn't even look at my chair.The second shop, though slightly more polite, was just the same, and the third and the fourth ---so I decided that my approach(way) must be wrong.I went into the fifth shop with a plan in my mind. I placed the chair on the floor and said to the shopkeeper, “Would you like to buy a chair?〞 He looked it over carefully and said, “Yes, not a bad chair. How much do you want for it, sir?〞“Twenty pounds,〞 I said.“OK,〞he said, “I’ll give you twenty pounds.〞“It’s got a slightly broken leg,〞 I said. “Yes, I saw that. It's nothing.〞Everything was going according to the plan and I was getting excited. “Wha t will youdo with it?〞I asked. “Oh, it will be easy to sell once the repair is done.〞“I'll buy it,〞 I said. “What do you mean?You’ve just sold it to me,〞he said. “Yes, I know but I’ve changed my mind. I'm sorry. I'll give you twenty -seven pounds for it.〞“You must be crazy,〞 he said. Then, suddenly the penny dropped. “I know what you want. You want meto repair your chair.〞“You’re right,〞I said. “And what would you have done if I had walked in and said, ‘Would you mend this chair for me?’ 〞“I would n't have agreed to do it,〞he said. “We don’t do repairs, not enough money in it and too much trouble. But I’ll mend this for you, shall we say for a fiver(five dollars )?〞 He was a very nice man and was greatly amused by the whole thing.36. The expressio n “the penny dropped〞 in the last paragraph means the shopkeeper ______.A. changed his mindB. accepted the offerC. saw the writer’s purposeD. decided to help the writer37. How much did the writer pay for the repair?A. £ 5.B. £ 7.C. £ 20.D. £ 27.38. From the text, we can learn that the writer was ______.A. honestB. carefulC. smartD. funnyBScratchy throats, stuffy〔堵塞(dǔsè)〕noses and body aches all result in discomfort, but being able to tell if the cause is a cold or flu may make a difference in how long the discomfort lasts, because the drugs available for the flu need to be taken soon after the illnesssets in. As for colds, the sooner a person starts taking over the medications available, the sooner relief will come.The common cold and the flu are both caused by viruses. More than 200 viruses can cause cold symptoms, while the flu is caused by three viruses — flu A, B and C. There is no cure for either illness, but the flu can be prevented by the flu vaccine〔疫苗(yìmiáo)〕, which is, for most people, the best way to fight the flu, according to the ALA.But the flu does strike, quick action can help. Although the flu and common cold have many similarities, there are some obvious signs to look for.Cod symptoms such as stuffy nose, running nose and scratchy throat typically developed gradually, and adults and teens often do not get a fever. On the other hand, fever is one of the characteristic features of the flu for all ages. And in general, flu symptoms including fever and coldness, painful throat and body aches come on suddenly and are more worrying than cold symptoms.The ALA notes that it may be particularly difficult to tell when babies and preschool age children have the flu. It advises parents to call the doctor if their small children have flu-like symptoms.Both cold and flu symptoms can be eased with the medications as well. However, children and teens with a cold or flu should not take aspirin for pain relief because of the risk of Reye syndrome〔综合症〕.There is, of cause, no vaccine for the common cold. But frequent hand washing and avoiding close contact with people who have colds can reduce the probability catching one.39. According to the author, knowing the cause of the discomfort will help ____________.A. prevent people from catching colds and the fluB. the patient obtain cheaper drugsC. the patient buy medicineD. shorten the period of the illness40. We learn from the passage that ____________.A. the drugs available can be taken to ease the discomfort caused by a cold or the fluB. one doesn’t need to take any medicine if he has a cold or the flueC. aspirin should not be included in the medicines for the fluD. delayed treatment of the flu will harm the liver and central nervous systems41. According to the passage, to fight against the flu effectively, one should ____________.A. take medicine upon catching the diseaseB. identify the virus which causes itC. consult a doctor as soon as possibleD. remain watchful when the disease is spreading42. Which of the following symptoms will distinguish the flu from a cold?A. A painful throat.B. A stuffy nose.C. A dry cough.D. A high temperature.43. If children have flu-like symptoms, their parents ____________.A. are encouraged to take them to hospital for vaccinationB. are advised not to give them aspirinC. should watch out for signs of Reye syndromeD. should prevent themCHow could we possibly think that keeping animals in cages in unnatural environments-mostly for entertainment purposes-is fair and respectful?Zoo officials say they are concerned about animals. However, most zoos remain “collections〞of interesting “things〞 rather than protective habitats(栖息地). Zoos teach people that it is acceptable to keep animals bored, lonely, and far from their natural homes.Zoos claim(声称(shēngchēng)) to educate people and save endangered species(物种), but visitors leave zoos without having learned anything meaningful about the anim als’ natural behavior, intelligence, or beauty. Zoos keep animals in small spaces or cages, and most signs only mention the species’ name, diet, and natural range(分布区). The animals’ normal behavior is seldom noticed because zoos don’t usually take care of the animals’ natural needs.The animals are kept together in small spaces, with no privacy and little opportunity for mental and physical exercise. This results in unusually and self-destructive behavior called zoochosis. A worldwide study of zoos found that zoochosis is common among animals kept in small spaces or cages. Another study showed that elephants spend 22 percent of their time making repeated head movements or biting cage bars, and bears spend 30 percent of their time walking back and forth, a sign of unhappiness and pain.Furthermore, most animals in zoos are not endangered. Captive breeding(圈养繁殖) of endangered big cats. Asian elephants, and other species has not resulted in their being sent back to the wild. Zoos talk a lot about their captive breeding programs because they do not want people to worry about a species dying out. In fact, baby animals also attract a lot of paying customers. Haven’t we seen enough competitions to name baby animals?Actually, we will save endangered species only if we save their habitats and put an end to the reasons people kill them. Instead of supporting zoos, we should support groups that work to protect animals’ natural habitats.44.How would the author describe the animals’ life in zoos?A.Dangerous. B.Unhappy. C.Natural. D.Easy.45.In the state of zoochosis, animals _________.A.remain in cages B.behave strangelyC.attack other animals D.enjoy moving around46.What does the author try to argue in the passage?A.Zoos are not worth the public support.B.Zoos fail in their attempt to save animals.C.Zoos should treat animals as human beings.D.Zoos use animals as a means of making money.47.The author tries to persuade readers to accept his argument mainly by _________.A.pointing out the faults in what zoos doB.using pictures he has taken at zoosC.questioning the way animals are protectedD.discussing the advantages of natural habitatsDBeauty has always been regarded as something praiseworthy. Almost everyone thinks attractive people are happier and healthier, have better marriages and more respectable jobs. Personal advisor give them better advice for finding jobs. Even judges are softer on attractive defendants, but in the executive circle, beauty can become a liability.While attractiveness is a positive factor for a man on his way up the executive ladder, it is harmful to a woman.Handsome male executives were considered as having more honesty than plainer ones; their success was connected not with ability but with factors such as luck.All unattractive women executives were thought to have more honesty and to be more capable than the attractive female executives. Interestingly, though, the rise of the unattractive overnight successes was connected more to personal relationships and less to ability than that of the attractive overnight successes.Why are attractive women not thought to be able? An attractive woman is considered to be more womanly and an attractive man more manly than the less attractive ones. Thus, an attractive woman has an advantage in traditionally female jobs, but an attractive woman in a traditionally manly position appears to lack the "manly" qualities required.This is true even in politics. "When the only clue is how he or she looks, people treat men and women differently," says Anne Bowman, who recently published a study on the effects of attractiveness on political candidates. She asked 125 undergraduate students to rank two groups of photographs, one of men and one of women, in order of attractiveness. The students were told what the photographs were of. They were asked to rank them again, in the order they would vote for them.The results showed that attractive males completely defeated unattractive men, but the women who had ranked most attractive unchangeably received the fewest votes.48. According to the passage, attractive people are those who are ______.A. good-lookingB. humorousC. well-educatedD. capable49. The author of the passage intended to show us that people' s views on beauty are ______.A. out-of-dateB. practicalC. reasonableD. one-sided50. Which is TRUE according to the passage?A. Appearance is important in finding a good job.B. Attractiveness is of great advantage to his or her success.C. Attractiveness is more of a disadvantage than an advantage to women when it comes to politics.D. Attractiveness has more effect on men than on women.51. In traditional female jobs, attractiveness ______.A. strengthens the womanly qualities requiredB. always makes it easier for women to succeed quicklyC. makes women look more honest and capableD. can be a liabilityEWhen the population of the port town began to suffer from poisoning, the police came to find the cause of the poison. They thought someone was poisoning the people on purpose but no one knew how it was possible. Soon people took the position that the pork was poisoned. It was a popular food everyone ate and it could have possibly made everyone sick. Anyone who had possession of pork would throw it out. Even the poorest of the poor wouldn’t eat pork. Signs were posted on poles and letters were sent to everyone to warn people of the pork. Shortly afterwards, even policemen in high positions were also getting sick.Soon it became political and popular. Politicians rushed to the town to talk about politics and promised how they would find the solution if they were elected. Everyone was so sick that they didn’t care about politics. Everyone was in a position where he or she didn’t know what to do anymore. They went to the post office to mail posts out asking for help. The poor town didn’t know how to deal with the situation.One day, a well-known scientist from New York came to the town with a huge box containing many instruments and his possessions. He went to pools and the port and made measurements. He was quiet and polite. Then one day he made a speech at a newspaper meeting-room to announce his findings.“I am sorry to say your water supply is so heavily polluted; it is poisoned. I know who has been poisoning you all for such a long time. It is you who have been poisoning yourselves with pollution. A great deal of rubbish has been thrown into the water day after day. No one here has taken good care of the environment. It is no wonder all of you have been sick.〞 Shocked at the news, the people present were lost in thought.52. Which is the correct order of the facts described in the story?a. People suffered from poisoning.b. Politicians came to make promises.c. People began to realize the real cause.d. Pork was thrown away.e. The water there was polluted.f. A scientist came to check the water.A. e, a, d, b, f, cB. e, a, d, c, f, bC. a, e, b, d, c, fD. f, c, d, b, e, a53. What does the underlined phrase “ "took the position" mean in the passage?A. took the jobB. took the placeC. held the opinionD. made the suggestion54. Which of the following statements is correct?A. Everyone was so sick of politics that they didn’t care about those politicians.B. According to the scientist from New York, not all the population in the town have takengood care of the environment.C. The reason why the people in the town got sick was that they ate the pork poisoned bythe heavily polluted water.D. if the people in the town hadn’t polluted the water supply, they would not have sufferedfrom poisoning or sickness.55. After reading the passage, we can infer that ________A. politicians took every chance to make themselves electedB. pork was the main food of the people in the townC. people in the town were not well-educatedD. even some police officers were getting ill六对话(duìhuà)填空(一共10小题;每一小题1分,满分是10分)请认真阅读下面对话,并根据各题所给首字母的提示,在答题卡右栏中标有题号的横线上,写出一个英语单词的完好、正确形式,使对话通顺。
