单选题Not every psychologist would agree that Internet or video - game dependency is a legitimately (合理地) diagnosable problem. Some suggest that pathological (非理智的) game - playing or Internet surfing is not an addiction per se (本身，就本笛而言), but a symptom of a deeper issue, such as depression or anxiety. But Cash believes the virtual world can be no less addicting than other activities, such as gambling. She describes her first patient who exhibited signs of compulsion (冲动): He had come to her in a moment of crisis 15 years ago - having discovered a text - only role - playing computer game that was conceptually similar to Dungeons and Dragons, he had begun dedicating nearly all of his time to the game. He got fired from his job at nearby Microsoft, and his marriage was falling to pieces. Cash realized he was showing the classical signs of addiction. "I was so intrigued.

单选题Cancer Unless you have gone through the experience yourself, or watched a loved one"s struggle, you really have no idea just how desperate cancer can make you. You pray, you rage, you bargain with God, but most of all you clutch at any hope, no matter how remote, of a second chance at life. For a few excited days last week, however, it seemed as if the whole world was a cancer patient and that all humankind had been granted a reprieve. Triggered by a front-page medical news story in the usually reserved New York Times, all anybody was talking about—on the radio, on television, on the Internet, in phone calls to friends and relatives-was the report that a combination of two new drugs could, as the Times put it, cure cancer in two years. In a matter of hours patients had jammed their doctors" phone lines begging for a chance to test the miracle cancer cure. Cancer scientists raced to the phones and fax lines to make sure everyone knew about their research too, generating a new round of headlines. The time certainly seemed ripe for a breakthrough in cancer. Only last month scientists at the National Cancer Institute announced that they were halting a clinical trial of a drug called tamoxifen—and offering it to patients getting the placebo—because it had proved so effective at preventing breast cancer (although it also seemed to increase the risk of uterine cancer). Two weeks later came the New York Times" report that two new drugs can shrink tumors of every variety without any side effects whatsoever. It all seemed too good to be true, and of course it was. There are no miracle cancer drugs, at least not yet. At this stage all the drug manufacturer can offer is some very interesting molecules, and the only cancers they have cures so far have been in mice. By the middle of last week, even the most breathless TV talk-show hosts had learned what every scientist already knew: that curing a disease in lab animals is not the same as doing it in humans. "The history of cancer research has been a history of curing cancers in the mouse," Dr. Richard Klausner, head of the National Cancer Institute, told the Los Angles Times. "We have cured mice of cancer for decades and it simply didn"t work in people."

单选题Look for Friendship in Cyberspace In so many ways, cyberspace mirrors the real world. People ask for information, play games, and share hobby tips. Others buy and sell products. Still others look for friendship, or even love. Unlike the real world, however, your knowledge about a person is limited to words on a computer screen. Identity and appearance mean very little in cyberspace, so even the shyest person can become a chat-room star. Usually, this "faceless" communication doesn't create problems. Identity doesn't really matter when you're in a chat room discussing politics or hobbies. In fact, this emphasis on the ideas them selves makes the Internet a great place for exciting conversation. Where else can so many people come together to chat? But some Internet users want more than just someone to chat with. They're looking for serious love relationships. Is cyberspace a good place to find love? That answer depends on whom you ask. Supporters of online relationships claim that the Internet allows couples to get to know each other intellectually first. Personal appearance doesn't get in the way. But critics of online relationships argue that no one can truly know another person in cyberspace. Why? Because the Internet gives users a lot of control over how others view them. Internet users can carefully craft their words to fit whatever image they want to give. In a sense, they're not really themselves. All of this may be fine if the relationship stays in cyberspace But not knowing a person is a big problem in a love relationship. This inevitably leads to disappointment when couples meet in person. So, before looking for love in cyberspace, remember the advice of Internet pioneer Clifford Stoll: "Life in the real world is far richer than anything you'll find on a computer screen. /

单选题{{B}}第二篇{{/B}} Cigars Instead Smoking one or two cigars a day doubles the risk of cancers of the lip, tongue, mouth, and throat, according to a government study. Daily cigars also increase the risk of lung cancer and cancer of the esophagus, and increase the risk of cancer of the larynx (voice box) six fold , say researchers at the National Cancer Institute in Bethesda, Maryland. In addition, the report revealed that smoking three or four cigars a day increased the risk of oral cancer to 8 times the risk for nonsmokers and the risk of esophageal cancer by four times the risk of nonsmokers. The health effects of smoking cigars is one of eight sections of the article "Cigars: Health Effects and Trends". The researchers report that, compared with a cigarette, a large cigar emits up to 90 times as much carcinogenic tobacco-specific nitrosamines. "This article provides clear and invalidating information about the disturbing increases in cigar use and the significant public health consequences for the country. " said Dr. Richard Riausner, director of the National Cancer Institute, in a statement. "The data are clear—the harmful substances and carcinogens in cigar smoke, like cigarettes, are associated with the increased risks of several kinds of cancers as well as heart and lung diseases. " he added. "In other words, cigars are not safe alternatives to cigarettes and may be addictive. " "To those individuals who may be thinking about smoking cigars, our advice is—don't. Tothose currently smoking cigars, quitting is the only way to eliminate completely the cancer, heart and lung disease risks. " warned Klausner. According to a National Cancer Institute press releases , there haven't been any studies on the health effects on nonsmokers at cigar social events, but "'"a significant body of evidence clearly demonstrates an increased lung cancer risk from secondhand smoke. "

单选题{{B}}第二篇{{/B}} {{B}} Common Problems, Common Solutions{{/B}} The chances are that you made up your mind about smoking a long time ago--and decided it's not for you. The chances are equally good that you know a lot of smokers--there are, after all about 60 million of them, work with them, and get along with them very well. And finally it's a pretty safe bet that you're open-minded and interested in all the various issues about smokers and nonsmokers--or you wouldn't be reading this. And those three things make you incredibly important today. Because they mean that yours is the voice--not the smoker's and not the anti-smoker's-- that will determine how much of society's efforts should go into building walls that separate us and how much into the search for solutions that bring us together. For one tragic result of the emphasis on building walls is the diversion of millions of dollars from scientific research on the causes and cures of diseases which, when all is said and done, still strike the nonsmoker as well as the smoker. One prominent health organization, to cite but a single instance, now spends 28 cents of every publicly contributed dollar on "education" (much of it in anti-smoking propaganda) and only 2 cents on research. There will always be some who want to build walls, who want to separate people from people, and up to a point, even these may serve society. The anti-smoking wall-builders have, to give them their due, helped to make us all more keenly aware of choice. But our guess, and certainly our hope, is that you are among the far greatest number who know that walls are only temporary at best, and that over the long run, we can serve society's interest better by working together in mutual accommodation. Whatever virtue walls may have, they can never move our society toward fundamental solutions. People who work together on common problems, common solutions, can.
