Some adults require little sleep; others need eight to ten hours in every twenty-four. Infants sleep sixteen to eighteen hours daily, the amount gradually going less as they grow older. Young students may need twelve hours; university students may need ten. A worker with a physically demanding job may also need ten, whereas an executive working under pressure may manage on six to eight. Many famous people are repute to have required little sleep. Napoleon Bonaparte, Thomas Edison, and Charles Darwin apparently averaged only four to six hours a night.
(77) Whatever your individual need, you can be sure that by the age of thirty you will have slept for a total of more than twelve years. By that age you will also have developed a sleep routine; a favorite hour, a favorite bed, a favorite posture (姿势), and a formula (程式) you need to follow in order to rest comfortably.
(78)Investigators have tried to find out how long a person can go without sleep. Several people have reached more than 115 hours nearly five days. Whatever the limit, it is absolute. Animals kept awake for from five to eight days have died of exhaustion. The limit for human beings is probably about a week.
The writer implies that ______.
A.sleep is important for good mental and physical health
B.a light sleep is as restful as a deep sleep
C.memory is improved during sleep
D.sleep is relatively unimportant for human beings
This important change in women' s life has only recently begun to have its full effect on women's economic position. Even a few years ago most girls left school and took a full-time job. However, when they married, they usually left work at once and never returned to it. Today the school-leaving age is sixteen, many girls stay at school after that age, and though women marry younger, more married women stay at work at least until shortly before their first child is born. Very many more afterwards return to full or part-time work. Such changes have led to a new relationship in marriage, with the husband accepting a greater share of the duties and satisfactions of family life.
We are told that in a family about 1900 ______.

B.seven or eight children lived to be more than five
C.the youngest child would be fifteen
D.four or five children died when they were five
It was inevitable that this primacy should have narrowed as other countries grew richer. Just as inevitably, the retreat from predominance proved painful. By the mid-1980s Americans had found themselves at a loss over their fading industrial competitiveness. Some huge American industries, such as consumer electronics, had shrunk or vanished in the face of foreign competition. By 1987 there was only one American television maker left, Zenith. (Now there is none: Zenith was bought by South Korea's LG Electronics. ) Foreign-made cars and textiles were sweeping into the domestic market. America's machine-tool industry was on the ropes. For a while it looked as though the making of semiconductors, which America had sat at the heart of the new computer age, was going to be the next casualty.
All of this caused a crisis of confidence. Americans stopped taking prosperity for granted. They began to believe that their way of doing business was failing, and that their incomes would therefore shortly begin to fail as well. The mid-1980s brought one inquiry after another into the causes of America's industrial decline. Their sometimes sensational findings were filled with warnings about the growing competition from overseas.
How things have changed! In 1995 the United States can look back on five years of solid growth while Japan has been straggling. Few Americans attribute this solely to such obvious causes as a devalued dollar or the turning of the business cycle. Self-doubt has yielded to blind pride. "American industry has changed its structure, has gone on a diet, has learnt to be more quick-witted," according to Richard Cavanagh, executive dean of Harvard's Kennedy School of Government. "It makes me proud to be an American just to see how our businesses are improving their productivity," says Stephen Moore of the Cato Institute, a think-tank in Washington, D. C. And William Sahlman of the Harvard Business School believes, that people will look back on this period as "a golden age of business management in the United States".

What I remember now about VE Day was the afternoon and the evening. It was a fine May day. I remember coming home at about five o'clock. My father and mother came in about an hour later. After dinner I said I wanted to see the bonfire (篝火), so when it got dark my father took me to the end of the street. The bonfire was very high, and some peo-ple had collected some old clothes to dress the unmistakable figure with the moustache (小胡子) they had put on top of it. Just as we arrived, they set light to it. The flames rose and soon covered the "guy." Everyone was cheering and shouting, and an old woman came out of her house with two chairs and threw them on the fire to keep the fire going.
I stood beside my father until the fire started to go down, not knowing what to say. He said nothing either. He had fought in the First World War and may have been remem-bering the end of that. At last he said, "Well, that's it, son. Let's hope that this time it really will be the last one. "

A.In a small city.
