单选题In China it is relatively usual to ask people their age, but in the west this question is generally regarded as impolite. This is particularly true 41 women, and even more 42 if the inquirer(问者)is a man. However, it is very 43 to ask children their age, and some adults may not mind being asked 44 . In fact, some elderly people are quite happy to 45 the age, especially if they feel they look young 46 their age. Nevertheless, it is not very wise to ask a 47 question like "How old are you?". If elderly people want to talk about their age, and perhaps receive a compliment(恭维话)on how young they look, they may easily bring 48 the topic themselves and ask the other to 49 how old they are. 50 such a situation, it is quite acceptable to discuss age 51 They normally expect to be complimented on their youthfulness, rather than 52 that they look very old. 53 Westerners do not usually ask people directly how old they are, this does not 54 that they are not interested to know how old other people ate. They may ask 55 for the information, 56 they may try to 57 the topic indirectly, sometimes discussions about educational 58 and the number of years of working experience may provide some 59 , but this is not always the 60 . Of course, individuals also vary in what they are interested or willing to talk about.

单选题It is not unusual for chief executives to collect millions of dollars a year in pay, stock options, and bonuses. In the last fifteen years, while executive remuneration rose, taxes in the highest income bracket went down. Millionaires are now commonplace. Amiability is not a prerequisite for rising to the top, and there are a number of chief executive officers with legendary bad tempers. It is not the boss's job to worry about the well-being of his subordinates although the man with many enemies will be swept out more quickly in hard times; it is the company he worries about. His business savvy is supposed to be based on intimate knowledge of his company and the industry so he goes home nightly with a full briefcase. At the very top—and on the way up—executives are exceedingly dedicated. The American executive must be capable of enough small talk to get him through the social part of his schedule, but he is probably not a highly cultured individual or an intellectual. Although his wife may be on the board of the symphony or opera, he himself has little time for such pursuits. His reading may largely concern business and management, despite interests in other fields. Golf provides him with a sportive outlet that combines with some useful socializing. These days, he probably attempts some form of aerobic exercise to "keep the old heart in shape" and for the same reason goes easy on butter and alcohol, and substances thought to contribute to taking highly stressed executives out of the running. But his doctor's admonition to "take it easy" fails on deaf ears. He likes to work. He knows there are younger men nipping at his heels. Corporate head-hunting, carried on by "executive search firms", is a growing industry. America has great faith in individual talent, and dynamic and aggressive executives are so in demand that companies regularly raid each other's managerial ranks.

单选题There are two factors which determine an individual"s intelligence. The first is the sort of brain he is born with. Human brains differ considerably, some being more capable than others. But no matter how good a brain he has to begin with, an individual will have a low order of intelligence unless he has opportunities to learn. So the second factor is what happens to the individual—the sort of environment in which he is reared. If an individual is handicapped environmentally, it is likely that his brain will fail to develop and he will never attain the level of intelligence of which he is capable. The importance of environment in determining an individual"s intelligence can be demonstrated by the case history of the identical twins(同卵双胞胎), Peter and Mark X. Being identical, the twins had identical brains at birth, and their growth processes were the same. When the twins were three months old, their parents died, and they were placed in separate foster homes. Peter was reared by parents of low intelligence in an isolated community with poor educational 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 stimulated intellectually. This environmental difference continued until the twins were in their late teens, when they were given tests to measure their intelligence. Mark"s I. Q. was 125, twenty-five points higher than the average and fully forty points higher than his identical brother. Given equal opportunities, the twins, having identical brains, would have tested at roughly the same level.
