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
C．Several thousand. D．About 15 percent.
4.Which is the best title for this passage?
A．How to seek a job in the USA. B．Doctors' immigration to the USA.

A few months ago, it wasn't unusual for 47-year-old Carla Toebe to spend 15 hours per day online. She'd wake up early, turn on her laptop and chat on Internet dating sites and instant-messaging programs – leaving her bed for only brief breaks. Her household bills piled up, along with the dishes and dirty laundry, but it took constant complaints from her four daughters before she realized she had a problem.
"I was starting to feel like my whole world was falling apart – kind of slipping into a depression," said Carla. "I knew that if I didn't get off the dating sites, I'd just keep going," detaching (使脱离) herself further from the outside world.
Toebe's conclusion: She felt like she was "addicted" to the Internet. She's not alone.
Concern about excessive Internet use isn't new. As far back as 1995, articles in medical journals and the establishment of a Pennsylvania treatment center for overusers aroused interest in the subject. But as reliance on the Web grows, there are signs that the question is getting more serious attention: Last month, a study published in CNS Spectrums claimed to be the first large-scale look at Internet overuse. The American Psychiatric Association may also consider listing Internet addiction in the next edition. And scores of online discussion boards have popped up, on which people discuss negative experiences tied to too much time on the Web.
The new CNS Spectrums study was based on results of a nationwide telephone survey of more than 2,500 adults. Like the latest survey, this one was conducted by Stanford University researchers. About 6% of respondents reported that "their relationships suffered because of excessive Internet use." About 9% attempted to conceal "nonessential Internet use," and nearly 4% reported feeling " still occupied by the Internet when offline."
"The Internet problem is still in its early stage," said Maressa Orzack, a Harvard University professor. No single online activity is to blame for excessive use, he said. "They're online in chat rooms, checking e-mail, or writing blogs. The problem is not limited to porn (色情) or gambling websites.”
“Excessive Internet use should be defined not by the number of hours spent online but in terms of losses.”said Maressa Orzack. "If it's a loss where you're not getting to work, and family relationships are breaking down as a result, then it's too much."
Since the early 1990s, several clinics have been established in the U. S. to treat heavy Internet users. They include the Center for Internet Addiction Recovery and the Center for Internet Behavior.
The website for Orzack's center lists the following among the psychological symptoms of computer addiction:
● Having a sense of happiness or excitement while at the computer.
● Longing for more and more time at the computer.
● Neglect of family and friends.
● Feeling empty, depremssed or irritable when not at the computer.
● Lying to employers and family about activities.
● Inability to stop the activity.
● Problems with school or job.
Physical symptoms listed include dry eyes, backaches, skipping meals, poor personal hygiene (卫生) and sleep disturbances.
“People who struggle with Internet overuse maybe depressed or have other mood disorders.” Orzack said. When she discusses Internet habits with her patients, they often report that being online offers a "sense of belonging, and escape, excitement and fun," she said. “Some people say relief…because they find themselves so relaxed.”
Some parts of the Internet seem to draw people in more than others. Internet gamers spend countless hours competing in games against people from all over the world. One such game, called World of Warcraft, is cited on many sites by posters complaining of a "gaming addiction."
Andrew Heidrich, an education network administrator from Sacramento, plays World of Warcraft for about two to four hours every other night, but that's nothing compared with the 40 to 60 hours a week he spent playing online games when he was in college. He cut back only after a full-scale family intervention (干预), in which relatives told him he'd gained weight.
“There's this whole culture of competition that sucks people in with online gaming, ”said Heidrich, now a father of two. People do it at the expense of everything that was a constant in their lives." Heidrich now visits websites that discuss gaming addiction regularly “to remind myself to keep my love for online games in check”.
Toebe also regularly visits a site where posters discuss Internet overuse. In August, when she first realized she had a problem, she posted a message on a Yahoo Internet addiction group with the subject line:“I have an Internet Addiction.”
“I'm self-employed and need the Internet for my work, but I'm failing to accomplish my work, to take care of my home, to give attention to my children,”she wrote in a message sent to the group. “I have no money or insurance to get professional help; I can't even pay my loan and face losing everything.”
Since then, Toebe said, she has kept her promise to herself to cut back on her Internet use. "I have a boyfriend now, and I'm not interested in online dating," she said by phone last week. "It's a lot better now."
1. What eventually made Carla Toebe realize she was spending too much time on the Internet?
A. Her daughter's repeated complaints.
B. Tiredness resulting from lack of sleep.
C. The poorly managed state of her house.
D. The high financial costs adding up.
2.What is the main idea of para4?
A. A study claimed to be the first large-scale look at Internet overuse.
B. The American Psychiatric Association plans to list Internet addiction in its edition.
C. There are heated discussions about negative experiences over internet overuse.

D. people got involved in online gambling
4. According to Orzack, people who struggle with heavy dependence on
