Concerning money or anything else, conflicts between husband and wife usually reflect a power struggle. Conflicts between parent and child often centre around the same issue. As children enter adolescence, they begin to demand greater freedom to go where they please, do what they please, and make decisions without parental interference. Many American parents do not know how to deal with their teenagers and seek advice from books, lectures, and parent training courses. Parents want to maintain a friendly relationship with their teenagers and also want to guide them so that their behavior. will be whatever the parents consider proper and constructive.
But in a society of rapidly changing social and moral values, parents and children often disagree about what is important and what is fight.
Arguments may concern such unimportant matters as styles of dress or hairdos. But quarrels may also concern school work, after school jobs, decisions, use of the family car, dating, and sex behavior. Some families have serious problems with teenagers who drop out of school, run away from home, or use illegal drugs. Because so much publicity is given to the problem teenager, one gets the impression that all teenagers are troublemakers. Actually, relatively few adolescents do anything wrong, and nearly all grow up into "solid citizens" who fulfill most of their parents’ expectations. In fact, recent studies show that the "generation gap" is narrowing. The vast majority of teenagers share most of their parents’ values and ideas. Many parents feel that they get along with their adolescents quite well.

The American population was the tallest in the world from about the American Revolution to World WarⅡ—that’s a long time.The U.S.had a very resource rich environment, with game, fish and wildlife. In fact we have data on disadvantaged people in America,such as slaves.They were obviously among the most mistreated populations in the world, but given the resource abundance，and given the fact that the slave owners needed their work,they had to be fed relatively decently. So the slaves were taller than European peasants. It’s no wonder that Europeans were just flooding to America.
Americans today are no longer the tallest people in the world.After World WarⅡ，many Western and Northern European countries began to adopt favorable social policies.There is universal health insurance in most of these societies—that,of course，makes a difference in health care.You can also consider income inequality in the U.S., since people who are at the low end of the totem pole(图腾柱)have considerable adversity making ends meet.I suspect the difference in height between Americans and Europeans is due to both diet and health care.
Americans today suffer from an additional problem:obesity.If children are too well nourished，then they’ re not able to grow optimally.There are certain hormones that control the start of the adolescent growth and the start of adolescence.Nutrition is one of the factors，along with genetic and hormonal ones which are associated with the start of puberty(青春期).And if puberty comes too early，then the youth will peak out sooner,and will not become as tall in adulthood as someone who had better nutrition.Also,the overload of carbohydrates and fats in a fast food diet may hinder the consumption of micro nutrients essential to growth.
1.The word "game" in(line 2，para.1)refers to.
(A). animals hunted for food
(B). rich natural resources
(C). activities played by kids
(D). sports events to be held
2.Slaves in America were taller than European peasants because.
(A). they were badly treated
(B). they did not do farm work
(C). they had sufficient food to eat
(D). they enjoyed better health care
3. It is implied in the second paragraph that.
(A). Europeans could make more money than Americans
(B). average Americans used to be shorter than Europeans
(C). welfare helps Europeans grow taller than Americans
(D). people on the totem pole are leading a comfortable life
4. According to the third paragraph,overweight children in the U.S..
A. tend to have better nutrition for growth
B. tend to eat more food to grow taller
C. will grow taller than average children
D. will fail to grow into an ideal height
5. Eating too much fast food may affect.
(A). the absorption of micronutrients
(B). the intake of carbohydrates
(C). the consumption of hormones
(D). the digestion of fats

Why should this be？ From the complexity of causes responsible for the present commonplace interview form, a few are worth singling out, such as the revolt against rationality and the worship of feeling in its place. To the young of the 60s, the painstaking search for understanding of a given political problem may have appeared less fruitful and satisfying than the free expression of emotion which the same problem generated. Sooner or later, broadcasting was bound to reflect this.
This bias against understanding has continued. To this we must add the professional causes that have played their part. The convention of the broadcast interview had undergone little change or radical development since its rise in the 50s. When a broadcasting form. ceases to develop, its practitioners tend to take it for granted and are likely to say "how" rather than ask "why".
Furthermore, these partly psychological, partly professional tendencies were greatly accelerated by the huge expansion of news and current affairs output over the last 15 years. When you had many, additional hours of current affairs broadcasting, interviewing turned out to be a far cheaper convention than straight reporting, which is costly in terms of permanent reporters and time preparation. The temptation to combine an expanded news and current affairs service with a relatively small additional financial expense by making the interview happen everywhere proved overwhelming.
To be fair, there are compensating virtues in interviewing, such as immediacy and authority, yet in all honesty I must say that the spread of the interviewing arrangement has led to a corresponding diminution of quality broadcasting.
According to the author, in the past politicians thought that television interviewers ______.
A．knew more about politics than they did
B．should be honoured to meet them
C．really were eager to be politicians too
D．gave them a difficult time in interviews

The West begun to take more notice of the East. (西方国家开始越来越关注东方国家)The fifth volume of an enormous work re-assessing the Chinese contribution to science and technology is to be published next year. The first volume, which was published twenty years ago, set the tone for the whole work. In it, evidence was given to show that many inventions which, until then, western historians had claimed for Europe, were made first in China. The attempt to rewrite the intellectual history of the world was not received without protest by some reputable historians. However, the evidence that has been presented so far in the first four volumes has persuaded many historians who were skeptical at first. China's invention of paper, printing, the magnetic compass and gunpowder has never been disputed, but this new history has added advanced bridge design, mechanical clocks, paddle boats and many other inventions to the list.
In the four volumes published so far no attempt has been made to explain why China has not kept up with the West in science and technology in modern times. It is probable that the answer is to be found in the social and economic history of China, where a static society under a relatively benevolent regime (仁慈的政体) of scholar-gentry (学者绅士) contrasts with the potentially revolutionary and dynamic society of the West at the end of the Middle Ages. In recent years, the Chinese government has been making every effort to catch up with the West again, and there is little doubt that the gap is being reduced year by year. But will China avoid the West's mistakes？
