A major new study shows that the situation may be changing. A large and rapid drop in the world's birth rate has taken place during the past 10 years. Families generally are smaller now than they were a few years ago. It is happening in both developing and industrial nations, Researchers said they found a number of reasons for this. More men and women are waiting longer to get married and are using birth control devices and methods to prevent or delay pregnancy. More women are going to school or working at jobs away from their homes instead of having children. And more governments, especially in developing nations, now support family planning programs to reduce population growth. China is one of the nations that has made great progress in reducing its population growth. China has already cut its rate of population growth by about one half since 1970. China now urges each family to have no more than one child. And it hopes to reach zero population growth, the number of births equaling the number of deaths, by the year 2000. Several nations in Europe already have fewer births than deaths. Experts said that these nations could face a serious shortage of workers in the future. And the persons who are working could face much higher taxes to help support the growing number of retired people. In Paragraph one, the sentence "Experts Dong have been concerned about such growth", the phrase "concerned about" is similar in meaning to______. A．worried about B．related to C．engaged in D．made a study of

Why is this？ Although the total growth rate of the world population will decrease(下降), in some countries there will be a big rise in the population. More people will be born in Third World countries than in the richer Northern countries. So the population will grow faster in poor countries; and the problems in these countries will be very serious. This is because the family is more likely to survive(幸存) if there are a lot of children to work for the members who become old or who cannot find work. A survey of the UN also shows that the growth rate is low where there is a higher level of income, better education, more health care and better living conditions. In this aspect, government plays an important role. So, the conclusion of the UN report is: "Look after the people and the population will look after itself." What can we learn about the growth rate of population？ A．The total growth rate of world population will increase. B．The growth rate of population in richer countries will increase. C．The growth rate of population in poor countries will increase. D．The total growth rate in American countries will increase.

On April 18, 1990, the Chinese central government made the announcement of opening up and developing Shanghai Pudong. That was seen as a major strategy to turn Shanghai into one of world's largest economic, financial and trade centers and to regenerate the economy of the Yangtze River Delta and even the whole Yangtze River Valley. The reconstruction of Pudong is a major strategic decision in carrying on the social and economic progress of China. It will lead the country in innovations of administrations, upgrading of industrial structures and expanding the practice of the opening-up policy. The past ten years have witnessed explosive economic growth in Pudong as well as an enormous change in the appearance of the city. Pudong New Area has become the landmark of Shanghai as one of the international economic centers in the 21st century. As the tallest building in China, Jin Mao Tower is au intelligent building offering services for business, hotel, recreation, sightseeing and shopping. It is not only a new tourist attraction but also a window through which people from other parts of the world may get a better understanding of Shanghai and Pudong. Pudong Land area:【46】.

Population control has long been a subject of discussion among researchers. Some have argued that the supply of good land is limited. In order to feed a large population, bad land must be cultivated and the good land overworked. As a result, each person produces less in a given amount of time and this means a lower average income than could be obtained with a smaller population. Other researchers have argued that a large population gives more scope for the development of facilities such as sports, roads and railways, which are not likely to be built unless there is a big demand to justify them. Similarly, it can be argued that the public costs of society will not be so heavy to each individual if they are shared among the members of a large population. One of the difficulties in implementing birth control lies in the fact that the official attitudes to population growth vary from country to country. In underdeveloped countries where a large 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. In a well-developed society the problem may be more complex. A declining birthrate may lead to unemployment because it results in a shrinking market. Cities with a declining population may have to face the prospect of a shrinking tax base and a fall in land values. If there are fewer children going to school, teachers may be thrown out of work. 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. The writer suggests that policy makers should consider cultural values ______. A．in carrying out family planning B．in producing birth control drugs C．in improving public health standards D．in introducing birth control techniques

A．the United States will be able to feed half the world by 2025 B．the future will see no more hunger C．we will encounter very serious problem in the near future D．the developed nations will change in the near future
