The 150 million people who live outside the country of their birth make up less than 2.5 percent of world population, but they have an importance far beyond their numbers. Some international migrants are refugees or students, but those with the most impact are economic migrants, drawn to places such as Los Angeles, where the wages may be three times greater than those in Bombay. These migrants tend to be young and willing to work for low wages. Though traditionally unskilled, a growing number are highly educated.Immigration is now the major contributor to demographic change in many developed countries. In the U.S., according to the latest U. S. Census Bureau projection, the population will grow by 129 million in the period from 2000 to 2050, but if immigration stops it would go up by just 54 million. Western Europe’s population is 42 percent greater than that of the U. S., but its projected immigration is only about half that of the U. S.; as a consequence, the region expected to lose 28 million people over the next 50 years. Japan, which has close to zero net migration, is projected to lose 26 million by 2050. (Deaths will start outrunning births in west Europe and Japan around the middle of this decade).During the past six years, the U. S. received 27 percent of the world international migrants, compared with 9 percent by Germany, the second most popular destination. One fourth of all migrants to the U. S. went to California; favorite cities, in order of the number of foreign-bom, are Los Angeles, New York City, San Francisco, Miami and Chicago.International migrants primarily come from developing countries, with China at 14 percent and Mexico at 8 percent being the latest sources. A few developing countries, such as Afghanistan, Bosnia, Liberia and Rwanda, have had significant influxes in recent years, but these reflect mainly the movement of refugees. Most developing countries had negative net migration.In the past few years, European country with considerable immigration has had a reaction against foreign work, according to social scientist Christopher Jencks of Harvard University. Some Asian countries hit hard by recession in the late 1990s tried to repatriate migrant workers. Thus far the U. S. shows no signs of reinstituting the extremely restrictive Immigration, laws of the past, a major reason being the dependence of many industries on a supply of foreign labor. Indeed, the AFL-CIO, once an opponent of high immigration quotas has reverse position and is now attempting to organize immigrant. This change in attitude among other reasons leads Jencks to conclude that a substantial reversal of the current liberal policies is unlikely.1.Which of the following statements does NOT exactly describe the economic migrants?2.According to the passage, the U.

Spread across the United States are about 500,000 doctors, cheeked by jowl, in the big cities and thin on the ground in isolated small towns. In June 1986, the secretary of health and human services, Dr. Otis Bowen, passed on a view of his experts: 5%-15% of America’s 500,000 doctors should be candidates for disciplinary action, many of them because of drug taking or alcoholism. Others give their patients poor care because they are senile, incompetent, guilty of misconduct or out of touch with developments in medicine.The granting, or withdrawal, of licenses to practice is in the hands of state medical boards, but they are overwhelmed with complaints and lack the money to handle even a fraction of them. Recently, however, things have been changing. In 1985, 406 doctors lost their licenses (compared with 255 in 1984), nearly 500 were placed on probation and nearly 1,000 received reprimands or had their right to practice curtailed. The federal inspector general demanded, and won the right for the states and the federal government, which provide health care for the elderly and for the poor under the Medicare and Medicaid programme, to refuse payment to the doctors considered unsatisfactory.Yet putting these powers into practice is proving to be far from easy. Of the 35 doctors so far denied reimbursement from Medicare, almost all work in lightly populated rural areas. On March 27th, their indignation and that of their patients were a sympathetic hearing by the Senate Finance Committee. Rural doctors may not be as up to date as those in the big towns, but they are often the only source of medical help for miles around and their patients are loyal to them. Members of the review boards, which are paid by the government, insist, however, that elderly and poor people should not be forced to receive (and the state to pay for) inferior care.An innovation is on the horizon in Texas, the most under-doctored state in the country (with only one doctor for every 1,100 residents). Lubbock University is setting up a computer network that will enable country doctors to obtain medical expertise and access to medical records in a hurry. The aim is to reduce the isolation of the country doctors and thus, in the long run, to attract more young doctors to rural areas.1.The main topic of the passage is （ ）.2.According to the text, disciplinary action should be taken against those who give patients poor care because of the following reasons EXCEPT （ ）.3.Which of the following is true about the unfit doctors?4.It can be inferred from the text that in the near future （ ）.5.The paragraph following the text would probably discuss（ ）.
