单选题 After their 20-year-old son hanged himself during his winter break from the University of Arizona five years ago, Donna and Phil Satow wondered what signs they had overlooked, and started asking other students for answers. What grew from this soul searching was Ulifeline (www. ulifeline, org), a website where students can get answers to questions about depression by logging on through their universities. The site has been adopted as a resource by over 120 colleges, which can customize it with local information, and over 1.3 million students have logged on with their college ID's. "It's a very, solid website that raises awareness of suicide, de-stigmatizes mental illness and encourages people to seek the help they need," said Paul Grayson, the director of counseling services at New York University, which started using the service nearly a year ago. The main component of the website is the Self-E-Valuator, a self-screening program developed by Duke University Medical Center that tests students to determine whether they areat risk for depression, suicide and disorders like anorexia and drug dependence. Besides helping students, the service compiles anonymous student data, offering administrators an important window onto the mental health of its campus. The site provides university users with links to local mental health services, a catalog of information on prescription drugs and side effects, and access to Go Ask Alice, a vast archive developed by Columbia University with hundreds of responses to anonymously posted inquiries from college students worldwide. For students concerned about their friends, there is a section that describes warning signs for suicidal behavior and depression. Yet it is hard to determine how effective the service is. The anonymity of the online service can even play out as a negative. "There is no substitute for personal interaction(个人互动才能解决)", said Dr. Lanny Berman, executive director of the American Association of Suicidology, based in Washington. Ulifeline would be the first to say that its service is no replacement for an actual therapist. "The purpose is to find out if there are signs of depression and then direct people to the right places," said Ron Gibori, executive director of Ulifeline. Mrs. Satow, who is still involved with Ulifeline, called it "a knowledge base" that might have prevented the death of her son, Jed. "If Jed's friends had known the signs of depression, they might have seen something," she said.

单选题{{B}}Passage 4{{/B}} Publication of this survey had originally been intended to coincide with the annual meetings of the World Bank and the International Monetary Fund, scheduled for September 29th-30th in Washington, D.C. Those meetings, and the big anti-globalization pro- tests that had been planned to accompany them, were among the least significant casualties of the terrorist atrocities of September 11th. You might have thought that the anti-capitalist protesters, after contemplating those horrors and their aftermath, would be regretting more than just the loss of a venue for their marches. Many are, no doubt. But judging by the response of some of their leaders and many of the activists (if Internet chat rooms are any guide), grief is not always the prevailing mood. Some anti-globalists have found a kind of consolation even a cause of satisfaction, in these terrible events--that of having been as they see it, proved right. To its fiercest critics, globalization, the march of international capitalism, is a force for oppression, exploitation and injustice. The rage that drove the terrorists to commit their obscene crime was in part, it is argued, a response to that. At the very least, it is suggested, terrorism thrives on poverty and international capitalism, the protesters say, thrives on poverty too. These may be extreme positions, but the minority that holds them is not tiny, by any means. Far more important, the anti-globalists have lately drawn tacit support if nothing else, reluctance to condemn--from a broad range of public opinion. As a result, they have been, and are likely to remain, politically influential. At a time such as this, sorting through issues of political economy may seem very far removed from what matters. In one sense, it is. But when many in the West are contemplating their future, with new foreboding, it is important to understand why the skeptics are wrong; why economic integration is a force for good; and why globalization, far from being the greatest cause of poverty, is its only feasible cure. Undeniably, popular support for that view is lacking. In the developed economies, support for further trade liberalization is uncertain; in some countries, voters are down- right hostile to it. Starting a new round of global trade talks this year will be struggle, and seeing it through to a useful conclusion will be. The institutions that in most people's eyes represent the global economy--the IMF, the World Bank and the World Trade Organization are reviled far more widely than they are admired; the best they can expect from opinion at large is grudging acceptance. Governments, meanwhile, are accused of bowing down to business, globalization leaves them no choice. Private capital moves across the planet unchecked. Wherever it goes, it bleeds democracy of content and puts "profits before people".

单选题Internet is a vast network ofcomputers that connects many of the world's businesses, institutions, and individuals．The internt, which means interconnected network of networks, links tens of thousands of smaller computer networks．These networks transmit huge amounts of infermation in the form of words, images, and sounds． The Internet was information on virtually every topic．Network users can search through sources ranging from vast databases to small electronic"bulletin boards"．where users form discussion groups around common interests．Much of the Internet's traffic consists of messages sent from one computer user to another．These messages are called electronic mail or e-mail． Internet users have electronic addresses that allow them to send and receive e-mail．Other uses of the network include obtaining news, joining electronic debates, and playing electronic games．One feature of the Internet, known as the World Wide Web, provides graphics, audio, and video to enhance the information in its documents．These documents cover a vast number of topics． People usually access the internt with a device called a modem．Modems connect computers to the network through telephone lines．Much of the Internet operates through worldwide telephone networks of fiber optic cables．These cables contain hair thin strands of glass that carry data as pulses of light．They can transmit thousands of times more data than local phone lines, most of which consist of copper wires． The history of the Internet began in the 1960s．At that time．the Advanced Research Projects Agency(ARPA) of the United States Department of Defense developed a network of computers called ARPAnet．Originally,ARPAnet connected only military and govemment computer systems． Its purpose was to make these systems secure in the event of a disaster or war．Soon after the creation of ARPAnet, universities and other institutions developed their own computer neavorks． These networks eventually were merged with ARPAnet to form the Internet．By the 1990s, anyone with a computer,modem, and Internet software could link up to the Internet． In the future, the Internet will probably grow more sophisticated as computer technology becomes more powerful．Many expels believe the Internet may become part of a larger network called the information superhighway．This network, still under development, would link computers with telephone companies, cable television stations, and other communication systems．People could bank, shop, watch TV,and perform many other activities through the network．
