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.

【小题1】Which of the following is not the reason for “the brain drain”?

E
A United Nations report says the number of people in the world is expected to reach 6500 million this July. By the middle of the century, the population could reach more than 9000 million. That would be an increase of 40﹪.
These numbers are fresh estimates for a report on world population change from 1950 to 2050. Hania Zlotnik is director of the U.N. Population Division. She says the world has added nearly 500 million people in the last six years.
But, in her words, "the good news is that new estimates show that it will take a little longer" to add the next 500 million. Mizz Zlotnik says this will probably happen by 2013.
The U.N. report says most population growth by 2050 will take place in less developed countries. Their population is expected to increase from 5000 million today to almost 8000 million. The population of more developed nations is expected to stay about the same, at just over 1000 million.
The report says nine countries will be responsible for about half the world population increase by 2050. These include Bangladesh, China, the Democratic Republic of Congo, Ethiopia and India. The others are Nigeria, Pakistan, Uganda and the United States.
Twelve countries are expected to have populations at least three times the size now. These include Afghanistan, Burkina Faso, Burundi, Chad, Congo and the Democratic Republic of Congo, and East Timor. The others are Guinea-Bissau, Liberia, Mali, Niger and Uganda.
The report says birth rates remain low in forty-four developed countries.
Today, worldwide, there is an average of two-point-six children per woman. This number is expected to fall to just over two children per woman in  2050. But U.N. population experts note that they cannot be sure which way birth rates will go in the future.
The U.N. report also notes that AIDS has increased death rates and slowed population growth in sixty countries. The area most affected by the disease is Southern Africa.
There, how long people live has fallen from an average of sixty-two years in 1995 to forty-eight now. Researchers believe life expectancy will fall to forty-three years by 2015, then begin a slow recovery.
67. Which of the following statements is true?
A. The population growth will slow down in the next few years.
B. Most population growth will take place in developed countries.
C. There is an average of 2.6 children per woman in developed countries.
D. The area most affected by AIDS is Uganda.
68. Which one is the best title of this passage?
A. AIDS slowed population growth.
B. Most population growth will take place in less developed countries.
C. Population growth and death rate.
D. UN world population report.
69．The author believes that the population growth results from_______
A. The birth rate in developed countries is too high.
B. The birth rate in developing countries is too high.
C. AIDS hit only a few countries.
D. A decrease in death rate.
70. Which of the following best describe the author’s attitude towards the rapid population growth?
A. sympathetic     B. happy       C. optimistic     D. critical
