阅读理解A youngster''s social development has a profound effect on his academic progress. Kids who have trouble getting along with their classmates can end up behind academically as well and have a higher chance of dropping out (退学). In the early grades especially, experts say, youngsters should be encouraged to work in groups rather than individually so that teachers can spot children who may be having problems making friends. "When children work on a project", says Lillian Kate, an educational professor at the University of Illinois, "they learn to work together, to disagree, to think, to take turns and lighten tensions. These skills can''t be learned through lecture. We all know people who have wonderful technical skills but don''t have any social skills. Relationships should be the first R." At a certain age, children are also learning to judge themselves in relation to others. For most children, school marks the first time that their goals are not set by an internal clock but by the outside world. Just as a 1-year-old struggling to walk, a 6-year-old is struggling to meet adults'' expectations. "Young kids don''t know how to distinguish between effort and ability." says Professor Hill, an early-childhood educator for the state of New Jersey, "If they try hard to do something and fail, they may conclude that they will never be able to accomplish a particular task. The effects of obvious methods comparison such as posting grades can be serious", says Hills, "a child who has had his confidence really damaged needs a rescue operation".

阅读理解What does the author tell us in this passage?

阅读理解Today anyone will accept money in exchange for goods and services. People use money to buy food, furniture, books, bicycles and hundreds of others they need or want. When they work,they usually get paid in money. Most of the money today is made of metal or paper. But people used to use all kinds of things as money. One of the first kinds of money was shells. Shells were not the only things used as money. In China, cloth and knives were used. In the Philippine Islands, rice was used as money. In some parts of Africa, cattle were one of the earliest kinds of money. Other animals were used as money, too. The first metal coins were made in China. They were round and had a square hole in the cen-ter. People strung them together and carried them from place to place. Different countries have used different metals and designs for their money. The first coins in England were made of tin. Sweden and Russia used copper to make their money. Later, other countries began to make coins of gold and silver. But even gold and silver were inconvenient if you had to buy something expensive. Again the Chinese thought of a way to improve money. They began to use paper money. The first paper money looked more like a note from one person to another than paper moneused toda . Money has had an interesting history from the days of shell money until today.

阅读理解The advantages and disadvantages of a large population have long been a subject of discussion among economists (经济学家). 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 worded 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 railways, which are not likely to be built unless there is a big demand to justify them. One of the difficulties in carrying out a world—wide 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 the 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 the highly industrialized society the problem may be more complex. A decreasing birth rate may lead to unemployment because it results in a declining market for manufactured goods. When the pressure of population on housing declines, prices also decline and the building industry is weakened. Faced with considerations such as these, the government of a developed country may well prefer to see a slowly increasing population, rather than one which is stable or in decline.
