14、ecide on the best choice. 58 Most of the people who appear most often and most gloriously in the history books are great conquerors and generals and soldiers, whereas the people who really helped civilization forward are often never mentioned at all. We do not know who first set a broken leg, or lau

15、nched a seaworthy boat, or calculated the length of the year, or manured(施肥于 ) a field; but we know all about the killers and destroyers. People think a great deal of them, so much that on all the highest pillars in the great cities of the world you will find the figure of a conqueror or a general o

16、r a soldier. And I think most people believe that the greatest countries are those that have beaten in battle the greatest number of other countries and ruled over them as conquerors. It is just possible they are, but they are not the most civilized. Animals fight; so do savages; hence to be good at

17、 fighting is to be good in the way in which animal or a savage is good, but it is not to be civilized. Even being good at getting other people to fight for you and telling them how to do it most efficiently-this, after all, is what conquerors and generals have doneis not being civilized. People figh

18、t to settle quarrels. Fighting means killing, and civilized peoples ought to be able to find some ways of settling their disputes other than by seeing which side can kill off the greater number of the other side, and then saying that that side which has killed most has won. And not only has it won,

19、but, because it has won, it has been in the right. For that is what going to war means; it means saying that might is right. That is what the story of mankind has on the whole been like. Even our own age has fought the two greatest wars in history, in which millions of people were killed or mutilate

20、d. And while today it is true that people do not fight and kill each other in the streets-while, that is to say, we have got to the stage of keeping the rules and behaving properly to each other in daily lifenations and countries have not learnt to do this yet, and still behave like savages. 58 The

21、first sentence of the passage tells us that _. （ A） most history books were written by conquerors, generals and soldiers （ B） those who really helped civilization forward is not mentioned in any history book （ C） conquerors, generals and soldiers should not be mentioned in history books （ D） history

22、 books tells us far more about conquerors and soldiers than about those who really helped civilization forward 59 According to the passage, most people believe that the greatest countries are those that _. （ A） built the highest pillars for their Conquerors （ B） were ruled by the greatest number of

23、conquerors （ C） won the greatest number of battles against other countries （ D） were beaten in battle by the greatest number of other countries 60 In the authors opinion, the countries that ruled over a large number of other countries are _. （ A） certainly not the greatest in any way （ B） neither th

24、e greatest nor the most civilized （ C） possibly the most civilized but not the greatest （ D） possibly the greatest in some sense but not the most civilized 61 The author says that civilized people should _. （ A） not have any quarrels to settle （ B） settle their quarrels without fighting （ C） not fig

25、ht when there are no quarrels to settle （ D） settle their quarrels by seeing which side can kill off the greater number of the other side 62 Which of the following is closest in meaning to the sentence “That is what going to war means; it means saying that might is right.“? （ A） Only those who are p

26、owerful should go to war. （ B） In a war only those who are powerful will win. （ C） Those who are right should fight against those who are wrong. （ D） Those who fight believe that the winner is right and the loser wrong. 62 The idea of test-tube babies may make you either delighted at the wonders of

27、modern medicine or irritated while considering the moral, or legal, or technological implications of starting life in a laboratory. But if youve ever been pregnant yourself, one thing is certain. You wonder what its like to carry a test-tube baby. Are these pregnancies normal? Are the babies normal?

28、 The earliest answers come from Australia, where a group of medical experts at the Queen Victoria Medical Center in Melbourne have taken a look at the continents first nine successful invitro pregnancies. The Australians report that the pregnancies themselves seemed to have proceeded according to pl

29、an, but at birth some unusual trends did show up seven of the nine babies turned out to be girls. Six of the nine were delivered by Caesarean section. And one baby, a twin, was born with a serious heart defect and a few days later developed life-threatening problems. What does it all mean? Even the

30、doctors dont know for sure, because the numbers are so small. The proportion of girls to boys is high, but until there are many more test-tube babies no one will know whether thats something that just happened to be like that or something special that happens when egg meets sperm in a test tube inst

31、ead of a fallopian tube. The same thin is true of the single heart defect. It usually shows up in only 15 out of 60000 births in that part of Australia, but the fact that it occurred in one out of nine test-tube babies does not necessarily mean that they are at special risk. One thing the doctors ca

32、n explain is the high number of Caesareans. Most of the mothers were older, had long histories of fertility problems and in some cases had had surgery on the fallopian tubes, all of which made them likely candidates for Caesareans anyway. The Australian researchers report that they are quite encoura

33、ged. All the babies are now making normal progress, even the twin with the birth defects. 63 What concern will the test-tube baby raise according to the passage? （ A） Whether the pregnancies of test-tube babies would be normal. （ B） Whether the test-tube babies would be encouraged. （ C） Why the prop

34、ortion of defected babies is so high. （ D） Why the number of Caesareans is so high. 64 What does the word “invitro“ underlined in Paragraph 2 most probably mean? （ A） Normal. （ B） Test-tube. （ C） Built-in. （ D） Formal. 65 Which of the following statements about the experiment mentioned in the passag

35、e is TRUE? （ A） Only the twins are defected. （ B） Most of the babies are delivered by means of Caesarean. （ C） There are some troubles during all mothers pregnancies. （ D） One baby appears to be abnormal. 66 Which of the following explanations regarding the high number of Caesarean operations is NOT

36、 true? （ A） Some mothers have passed the best age for a natural delivery. （ B） Some mothers have fertility problems. （ C） Some mothers favor the operations of this type. （ D） Some mothers have had surgical operations on their fallopian tubes. 67 What is the authors tone in this passage? （ A） Depress

37、ed. （ B） Optimistic. （ C） Opposing. （ D） Negative. 三、 Part V Cloze (15 minutes) Directions: There are 20 blanks in the following passage.
