Part II Reading Comprehension (30 points) Section A Directions: There are two passages in this part. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A) , B) , C) and D). You should decide on the best choice and mark the corresponding letter on the Answer Sheet with a single line through the center. Passage One As people generally use the word “honor ” they do not do so in the context of thinking about moral virtue. As a result they often confuse honor with fame. A virtuous person is an honorable person, a person who ought to be honored by the community in which he or she lives. But the virtuous person does not seek honor, being secure in his or her own self-respect. Lack of honor does not detract from the efficacy of moral virtue as an operative factor in the pursuit of happiness —as a means to leading a good human life. Virtuous persons may be considered fortunate if their virtue is recognized and publicly applauded. Persons lacking moral virtue can achieve fame as readily as, or perhaps more easily than, those who have a high degree of moral virtue. Fame belongs to the great, the outstanding, and the exceptional, without regard to their virtue or lack of it. Infamy is fame, no less than popularity. The great scoundrel can be as famous as the great hero. There can be famous villains as well as famous saints. Existing in the reputation a person has, regardless of his or her accomplishments, fame does not tarnish as honor does when it is unmerited. We normally desire the esteem of our fellow human beings, but is not this wish for the esteem of others a desire for fame rather than for honor? A virtuous person will not seek fame or be unhappy for lack of it. For fame can be enjoyed by bad men and women, as well as good. When it is enjoyed by virtuous persons without being sought by them, it is not distinguishable from honor, for then it is deserved. 31. What does this passage mainly talk about? A. A virtuous person achieves both honor and fame. B. A virtuous person does not seek honor or fame. C. Honor and fame are different concepts. D. Honor and fame are not distinguishable. 32. A virtuous person leads a good human life by means of _________. A. presuming happiness B. achieving moral virtue C. seeking honor D. seeking fame 33. What tends to tarnish with time? A. The reputation a person has. B. A high degree of moral virtue. C. A person ’s accomplishments. D. Honor that is undeserved. 34. Fame differs from honor in that _______. A. bad men and women can enjoy fame B. the great people can enjoy fame C. fame can fade in color D. virtuous persons will not seek fame 35. Which of the following statements is TURE? A. A virtuous person deserves honor. B. A famous person deserves honor. C. A virtuous person is publicly identified. D. A famous person has great accomplishments. Passage Two If you want to teach your children how to say sorry, you must be good at saying it yourself, especially to your own children. But how you say it can be quite tricky. If you s ay to your children “I’m sorry I got angry with you, but …”, what follows that “but” can render the apology ineffective: “I had a bad day” or “your noise was giving me a headache ” leaves the person who has been injured feeling that he should be apologizing for his bad behavior in expecting an apology. Another method by which people appear to apologize without actually doing so is to say “I’m sorry you’re upset”; this suggests that you are somehow at fault for allowing yourself to get upset by what the other person has done.院系：班级： 姓名：学号：考场地点装订线Then there is the general, all covering apology, which avoids the necessity of identifying a specific act that was particularly hurtful or insulting, and which the person who is apologizing should promise never to do again. Saying “I’m useless as a parent” does not commit a person to any specific improvement. These pseudo-apologies are used by people who believe saying sorry shows weakness. Parents who wish to teach their children to apologize should see it as a sign of strength, and therefore not resort to these pseudo-apologies. But even when presented with examples of genuine contrition, children still need help to become aware of the complexities of saying sorry. A three-year-old might need help in understanding that other children feel pain just as he does, and that hitting a playmate over the head with a heavy toy requires an apology. A six-year-old might need reminding that spoiling other children’s expectations can require an apology. A 12-year-old might need to be shown that raiding the biscuit tin without asking permission is acceptable, but that borrowing a parent’s clothes without permission is not. 36. If a mother adds “but” to an apology, _______. A. she doesn’t feel that she should have apologized B. she does not realize that the child has been hurt C. the child may find the apology easier to accept D. the child may feel that he owes her an apology 37. According to the author, saying “I’m sorry you’re upset” most probably means “_______”. A. You have good reason to get upset B. I’m aware you’re upset, but I’m not to blame C. I apologize for hurting your feelings D. I’m at fault for making you upset 38. It is not advisable to use the general, all-covering apology because _______. A. it gets one into the habit of making empty promises B. it may make the other person feel guilty C. it is vague and ineffective D. it is hurtful and insulting 39. We learn from the last paragraph that in teaching children to say sorry _______. A. the complexities involved should be ignored B. their ages should be taken into account C. parents need to set them a good example D. parents should be patient and tolerant 40. It can be inferred from the passage that apologizing properly is _______. A. a social issue calling for immediate attention B. not necessary among family membersC. a sign of social progressD. not as simple as it seems Section B: Directions: In this section, there is a passage with ten blanks. You are required to select one word for each blank from a list of choices given in a word bank following the passage. Read the passage through carefully before making your choices. Each choice in the blank is identified by a letter. You may not use any of the words in the bank more than once. Blanks 41 to 50 are based on the following passage. There are two factors which determine an individual ’s intelligence. The first is the sort of brain he is born with. Human brains differ 41 , some being more capable than others. But no matter how good a brain he has to begin with, a (an)42 will have a low intelligence unless he has opportunities to learn. So the second factor in what happens to the individual is the sort of environment in which he is 43 . If an individual is handicapped environmentally, it is likely that his brain will fail to develop. And he will never 44 the level of intelligence of which he is capable. The importance of environment in determining an individual ’s intelligence can be 45 by the case history of the identical twins, Peter and Mark. Being identical, the twins had identical brain at birth, and their growth processes were the same. When the twins were three months old, their parents died, and they were placed in 46 foster homes. Peter was reared by parents of low intelligence in an isolated community with poor 47 opportunities. Mark was reared in the home of well-to-do parents who had been to college. He was read to as a child, sent to good schools, and given every opportunity to be 48 intellectually. This environmental difference continued until the twins were in their late teens, when they were given tests to 49 their intelligence. Mark ’s I.Q. was 125, twenty-five points higher than the 50 , and fully forty points higher than his identical brother. Given equal opportunities, the twins, having identical brains, would have scored at roughly the same level.院系： 班级： 姓名：学号：考场地点装订线Part III Vocabulary and Structure (10 points) Directions: There are 20 incomplete sentences in this part.
