15、最佳選項(xiàng)。ALanguage as a System of SymbolsOf all systems of symbols(符號(hào)), language is the most highly developed. It has been pointed out that human beings, by agreement, can make anything stand for anything. Human beings have agreed, in the course of centuries of mutual(相互的)dependency, to let the various

16、noises that they can produce with their lungs, throats, tongues, teeth, and lips systematically stand for certain happenings in their nervous systems. We call that system of agreements language. There is no necessary connection between the symbol and that which it stands for. Just as social position

17、s can be symbolized by feathers worn on the head, by gold on the watch chain, or by a thousand other things according to the culture we live in, so the fact of being hungry can be symbolized by a thousand different noises according to the culture we live in. However obvious these facts may appear at

18、 first glance, they are actually not so obvious as they seem except when we take special pains to think about the subject. Symbols and the things they stand for are independent of each other, yet we all have a way of feeling as if, and sometimes acting as if, there were necessary connections. For ex

19、ample, there are people who feel that foreign languages are unreasonable by nature; foreigners have such funny names for things, and why cant they call things by their right names? This feeling exhibits itself most strongly in those English and American tourists who seem to believe that they can mak

20、e the natives of any country understand English if they shout loud enough. Like the little boy who is reported to have said: “Pigs are called pigs because they are such dirty animals,” they feel that the symbol is inherently(內(nèi)在地) connected in some way with the things symbolized. 61. Language is a hi

21、ghly developed system of symbols because human beings _. A. have made use of language for centuriesB. use our nervous systems to support languageC. have made various noises stand for any eventsD. can make anything stand for anything by agreement62. WhaLanguage is a highly developed system of symbols

22、 because human beings _. t can we conclude from Paragraph 2?A. Different noises may mean different things. B. Our culture determines what a symbol stands for. C. The language we use symbolizes our social positions. D. Our social positions determine the way we are dressed. 63. In Paragraph 3, “take s

23、pecial pains” probably means “_”. A. try very hardB. take our timeC. are very unhappyD. feel especially painful64. The example of the little boy is used to show that _. A. adults often learn from their youngB. “pig” is a dirty word because pigs are dirtyC. words are not connected with the things the

24、y stand forD. people sometimes have wrong ideas about how language worksBDoctors may now be able to stop many heart attacks. An important new study reports that doctors have a new drug. This drug is called TPA. It may be better than any other heart drugs. Many doctors now use a drug called streptoki

25、nase. But this drug sometimes causes problems for patients. It can even cause bleeding（流血）in the brain. Some doctors do not use streptokinase. Streptokinase can save about 1/3 of the people with heart attacks. But TPA will save about 2/3. One reason TPA can help more people is because of time. This

26、new drug is easier and faster to use. It will give doctors more time in hospitals. Then they can study the problem well. People with heart problems can also keep some TPA at home. When a heart attack starts, they can take some TPA right away. Then they will have time to get to the hospital. This is

27、important because about 860,000 people in the United States die before they get to the hospital. This is another reason why TPA is good news for people with heart attacks. According to the study, it is much safer; it doesnt cause other problems like streptokinase does. TAP works only on the heart. I

28、t does not have an effect on the blood or cause bleeding. Doctor plan to do more studies about TAP. They need to test this new drug on many more people with heart attacks. But in a few years, many doctors and hospitals will probably start using this exciting new drug. 65. In your opinion, the best t

29、itle for this passage is . A. Heart Attacks B. A New Drug for Heart AttacksC. The Cause of Heart Attacks D. A Drug Called Streptokinase66. The story says that TPA . A. is safer and faster than the old drug B. is very dangerousC. is slower and harder to use than the old drugD. causes many problems67.

30、 This new drug may mean . A. more people will die from heart attacksB. the same number of people will die from heart attacksC. fewer people will die from heart attacksD. no one will die from heart attacks68. Which of the following is TRUE? A. Streptokinase is the new drug for heart attacksB. TPA can

31、 save fewer people with heart attacks that streptokinaseC. people who take TPA at home before they go to hospital must be very careful. D. Probably TPA will be widely used in America in the following years. CThe Sahara Festival is a celebration of the very recent past. The three-day event is not fix

32、ed to the same dates each year, but generally takes place in November or December. It is well attended by tourists, but even better attended by locals. During the opening ceremonies, after the official greetings from the government leaders, people who attend the festival begin to march smartly befor

33、e the viewing stands, and white camels transport their riders across the sands. Horsemen from different nations display their beautiful clothes and their fine horsemanship. One following another, groups of musicians and dancers from all over the Sahara take their turns to show off their wonderful tr

34、aditional culture. Groups of men in blue and yellow play horns and beat drums as they dance in different designs. On their knees in the sand, a group of women in long dark dresses dance with their hair: their long, dark, shiny hair is thrown back and forth in the wind to the rhythm of their dance. T

35、he local and visiting Italian dogs are anxious to run after hares. The crowd is on its feet for the camel races. Camels and riders run far into the distance, and then return to the finish Line in front of the cheering people. Towards the evening, there comes the grand finale of the opening day, an e

36、xtremely exciting horserace. All the riders run very fast on horseback. Some riders hang off the side of their saddles. Some even ride upside down-their legs and feet straight up in the air-all at full speed. Others rush down the course together, men arm in arm, on different horses. On and on they w

37、ent. So fast and so wonderful!69. The Sahara Festival is a festival which_. A. has a very long history in North AfricaB. is held in the same place on the same dayC. is attended mainly by the people in the SaharaD. is celebrated mostly by travelers from different countries70. Before the races begin,

38、_ take part in the activities during the opening ceremonies. A. musicians, dancers, horses and haresB. camel riders, musicians, dogs and haresC. horsemen, dancers, camels and dogsD. musicians, officials, camels and horses71. The underlined word finale in the fourth paragraph most probably means the

39、_of the opening day. A. first part B. middle C. last part D. whole72. This passage mainly tells readers_. A. what happens on the opening day of the Sahara FestivalB. how people celebrate during the three-day Sahara FestivalC. what takes place at the closing ceremonies of the Sahara FestivalD. how an

40、imals race on the first and the last days of the Sahara FestivalDFrom the moment that an animal is born it has to make decisions. It has to decide which of the things around it are for eating, and which are to be avoided; when to attack and when to run away. The animal is, in fact, playing a very da

41、ngerous game with its environment, a game in which it must make decisiona matter of life or death. Animals ability to act reasonably is believed to come partly from what we may call “genetic (遺傳性的)learning”, which is different from the individual (個(gè)體的) learning that an animal does in the course of i

42、ts own lifetime. Genetic learning is learning by a speciesanimals of the same kindas a whole, and it is achieved by selection of those members of each generation that happen to act in the right way. However, the role of genetic learning depends upon how similar the future environment is to the past.

43、 The more important individual experience is likely to be, the less important is genetic learning as a means of getting over the problems of the survival game. Because most animals live in ever changing environments from one generation to the next, it is not surprising to find that very few species

44、indeed depend wholly upon genetic learning. In the great majority of animals, their particular ways of acting in a new environment are a compound (復(fù)合體) of individual experience added to the action patterns animals are born with. That is why animals can survive. 73The animals life will come to an end

45、 _ . Aif the animal makes a wrong decision Bif the animal plays a dangerous game Cwhen the animal attacks its enemy Dwhen the animal runs too slowly74Very few species depend entirely on genetic learning because _ . Aeach generation has its own way of learning Btheir environments change all the time

46、Cthey can act reasonably on their own Dit takes their whole life to learn75When the environment doesnt change much, _. Aanimals cannot act in a right way Bgenetic learning is less important for animals Cindividual learning plays a less important role Danimals cannot get over problems on their own76A

47、nimals living on generation after generation depends on _ . Atheir natural action pattern with their own experience Bthe lessons they have learnt during their lifetime Ctheir experience in particular environments Dthe knowledge passed on by their parentsESome British and American people like to invi

48、te friends for a meal at home. You should not be upset if your English friends dont invite you home. It doesnt mean they dont like you！Dinner parties usually start between 7 p. m. and 8 p. m. and end at about 11 p. m. Ask your host what time you should arrive. Its polite to bring flowers, chocolates

49、 or a bottle of wine as a gift. Usually the evening starts with drinks and snacks. Do you want to be extrapolite? Say how much you like the room, or the pictures on the wall. But rememberits not polite to ask how much things cost. In many families, the husband sits at one end of the table and the wi

50、fe sits at the other side. They eat with their guests. Youll probably start the meal with soup or something small, then youll have meat or fish with vegetables, and then dessert, followed by coffee. Its polite to finish everything on your plate and to take more if you want it. Did you enjoy the even

51、ing? Call your hosts the next day, or write them a short“Thank you”letter. British and American people like to say“Thank you, thank you, thank you”all the time!77.
