In recent years, especially during the l960s, there was much discussion about “the brain drain (排干, 流失),” which dealt with the problem of students and learned people who left their own countries for other countries that offered better chances for study, research, and employment.For example, according to a report from U.N., between 1962 and l966 more than 50 percent of all engineering graduates of Iran and 14 percent of Iranian scientists left their country for work abroad.Over 30 percent of Chilean engineers and 15 percent of Turkish physicians also went to work in other countries.Probably the greatest brain drain occurred among young scientists who had gone abroad to study.Many of them had planned to return to their countries to teach but chose to remain in more industrialized nations where they were able to continue their work and their research in fields in which there were no job possibilities at home.The countries that attracted most of these scientists were the United States, Great Britain, Germany, France, Canada, and Australia.

  Recent studies show that the brain drain to the United States may be decreasing.Many foreign scientists are going home again, and in some cases American scientists are leaving the United States for employment in other countries.The main reasons are that good jobs are becoming fewer here, money for national research has been sharply cut, and university fellowships reduced too.However, in the field of medicine the drain to the United States still goes on.Today more than one of every five American doctors is foreign - born, and several thousand foreign doctors immigrate to the United States each year.Over eighty countries have asked the State Department to send students who are skilled in important fields such as medicine back home when their study programs are over.

1.Which of the following is not the reason for “the brain drain”?

A.Good housing.             B.Better research condition.

C.Good job possibility        D.Better chances of study..

2.The brain drain to the United States may be decreasing mainly because __________.

A.many foreign scientists are ordered to return to their motherlands

B.they don't need any foreign scientists now

C.there are fewer and fewer good jobs in the USA

D.the universities refuse to provide money for the foreign scientists

3.How many American doctors are foreign - born?

A.About half of them.    B More than 20 percent

  There is a definite possibility that the climate of the world may be changing.Some scientists imagine that this could even mean the beginning of another ice age.The effects of such a change in climate on the human population of the world would be startling(惊人的).

  Recent research suggests that the general warming trend of the past hundred years or so may be coming to an end.During the past ten years, meteorologists tell us the average temperature of the Earth has dropped about one degree Fahrenheit.This does not seem like much, but it could have effects on wind and rain patterns which influence the overall weather picture.If these patterns change a lot, it could mean that certain regions of the world may continue to have long droughts while others will possibly suffer from widespread flooding.

  What regulates(调节)the climate is not exactly known.Meteorologists believe that clouds may be an important factor in regulating the amount of solar heat held by the Earth, which in turn determines the temperature of the planet.Another possibility is that man's industrial and agricultural methods may be affecting the natural weather patterns.However, the weather is not understood well enough for scientists to say for certain what is happening to the climate and what side effects this will actually have on the world's population.

[  ]

A.

A meteorologist is a person who ________.

[  ]

A.

B.

thinks there will be another ice age

C.

D.

  By the early 19th century the factory system had spread to the U.S. The first cotton factory was built in 1814, and by 1850 some 24 percent of workers were women. They produced clothing, shoes, cigars, and other things. In the Northeast, newly-arrived women with little education became the factory force. In the South, black women moved into factory and domestic(家庭的)jobs, first as slaves and later as free workers.

  By 1890 nearly 4 million women in the U.S. worked for pay. This represented(代表)18 percent of the female population aged 14 and 17 percent of the total work force. Half the female workers were under 25 years of age, and seven out of ten were single. Most of them worked in domestic service, teaching positions, and textile(纺织的)factories; only about 5 percent were secretaries, clerks, or salespersons.

  Recent years have seen a rapid increase in the number of women joining the paid labour force in the U.S. Today, almost 54 percent of all women of working age are employed. Over 50 percent of working women are married, and 60 percent of working wives have school--aged children.
