DDCDC (3) During the rest of sleep, the fatigue of the body disappears and recuperation (复原) begins. The tired mind gathers new energy; the memory improves; and annoyance and problems are seen correctly. 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 decreasing 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 great pressure may manage on six to eight. Many famous people are well known to have required little sleep. Napoleon Bonaparte, Thomas Edison, and Charles Darwin apparently averaged only four to six hours a night. 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 you need to follow in order to rest comfortably. 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. 1. It is implied in the passage that _______

It has been argued that the supply of good land is limited. To feed a large population, inferior land must be cultivated and the good land worked intensively. Thus, each person produces less and this means a lower average income than could be obtained with a smaller population Other economists have argued that a large population gives more scope for specialization and the development of facilities such as ports, roads and rail ways, which are not likely to be built unless there is a big demand to justify them One of the difficulties in carrying out a worldwide birth control program lies in the fact that official attitudes to population growth vary from country to country depending on the level of industrial development and the availability of food and raw materials. In a developing country where a vastly expanded population is pressing hard upon the limits of food, space and natural resources, it will be the first concern of government to place a limit on the birthrate, whatever the consequences may be In a highly industrialized society the problem may be more complex. A decreasing birthrate may lead to unemployment because it results in a declining market for manufactured goods.

DCABD The whole industrial process, which makes many of the goods and machines we need and use in our daily lives, is bound to create a number of waste products which upset the environment balance, or the ecological balance as it is also known. Many of these waste products can be prevented or disposed of sensibly, but clearly while more and more new goods are produced and made complex, there will be new, dangerous wastes to be disposed of, for example the waste products from nuclear power stations. Man people, therefore, see pollution as only part of a larger and more complex problem, that is, the whole process of industrial production and consumption of goods. Others again see the problem mainly in connection with agriculture, where new methods are helping farmers grow more and more on their land to feed our ever increasing populations. However, the land itself is gradually becoming worn out as it is being used, in some cases, too heavily, and artificial fertilizers cannot restore the balance Whatever its underlying reasons, there is no doubt that much of the pollution caused could be controlled if only companies, individuals and governments would make more efforts. In the home there is an obvious need to control litter and waste. Food comes wrapped up three or four times in packages that all have to be disposed of, drinks are increasingly sold in bottles or tins which cannot be reused. This not only causes a litter problem, but also is a great waste of resources, in terms of glass, metals and paper.

By: 1985, the latest year for which figures are available, it has climbed to 74.7 years Second, the U.S. birthrate rose in the mid-1900s, interrupting a long, slow decline. a dramatic increase occurred during this brief rise. From 1945 to 1947, the rate jumped from 20.4 births for every 1,000 people to 26.6. In 1957, the birthrate was still high -253-but then began to decline.
