单选题The Fat Problem that Men Face It is a pleasure to see men of a certain age worrying about their weight. Listening to them is not such a pleasure. Because the men are new at the game, they don't hesitate to discuss the fat problem incessantly. However women of the same age do not discuss the fat problem, especially not in mixed company. They prefer to face the problem with quiet dignity. Discussing the problem might only draw attention to some stray body part that may be successfully tucked away under an article of clothing. The age at which a man begins to explore the fat problem can vary. The actual problem can manifest itself in the early 30's, but broad-range discussion usually starts later. There are early nonverbal symptoms. I've watched the rugged journalist who shares my apartment sneak by with a Diet Coke. His shirts are no longer neatly tucked in to display a trim waist. Recently he has begun to verbalize his anxiety. He tells me, with a sheepish grin, that he is taking his suits to Chinatown to have them "tailored". Still-older men have lost their dignity and rattle on unabashedly. Often wives and children play important roles in their fat-inspection rituals. Take my oldest brother, a former college football player. His daughter says that several times a day he will stand at attention and call out, "Fat, medium or thin?" She knows the correct answer medium. Thin would be an obvious stretch, and fat may not get her that new video. According to his wife, he stands in front of the mirror in the morning(before the day's meals take their toll),puts his hands behind his head and lurches into a side bend, then clutches the roll that has developed and says, "Am I getting fatter? "His wife is expected to answer, "You look like you may have lost a few pounds. " And then there are the ex-husbands a pitiful group. They are extremely vocal. When I go to the movies with one, he confides that he is suffering from great hunger because he is dieting. He hasn't eaten since the pancakes and sausages he wolfed down that morning. He pauses in his monologue while he buys his popcorn. After the movie, we sprint to a restaurant, where he again pauses to devour a basket of bread. Before he orders his chaste salad and soup, he grows plaintive. Do I think he's fat?

单选题Internet-based Instruction By almost any measure, there is a boom in Internet-based instruction. In just a few years, 34 percent of American universities have begun offering some form of distance learning (DL), and among the larger schools, it"s closer to 90 percent. If you doubt the popularity of the trend, you probably haven"t heard of the University of Phoenix. It grants degrees entirely on the basis of online instruction. It enrolls 90,000 students, a statistic used to support its claim to be the largest private university in the country. While the kinds of instruction offered in these programs will differ, DL usually signifies a course in which the instructors post syllabi (课程大纲), reading assignments, and schedules on Websites, and students send in their assignments by e-mail. Generally speaking, face-to-face communication with an instructor is minimized or eliminated altogether. The attraction for students might at first seem obvious. Primarily, there"s the convenience promised by courses on the Net: you can do the work, as they say, in your pajamas (睡衣). But figures indicate that the reduced effort results in a reduced commitment to the course. While drop-out rates for all freshmen at American universities is around 20 percent, the rate for online students is 35 percent. Students themselves seem to understand the weaknesses inherent in the setup. In a survey conducted for eCornell, the DL division of Cornell University, less than a third of the respondents expected the quality of the online course to be as good as the classroom course. Clearly, from the schools" perspective, there"s a lot of money to be saved. Although some of the more ambitious programs require new investments in servers and networks to support collaborative software, most DL courses can run on existing or minimally upgraded (升级) systems. The more students who enroll in a course but don"t come to campus, the more the school saves on keeping the lights on in the classrooms, paying doorkeepers, and maintaining parking lots. And, while there"s evidence that instructors must work harder to run a DL course for a variety of reasons, they won"t be paid any more, and might well be paid less.

单选题Something Men Do Not Like to Do Eric Brown hates shopping. "It"s just not enjoyable to me," said the 28-year-old Chicago man who was carrying several shopping bags along the city"s main street, Michigan Avenue. "When I"m out 1 , I basically know what I want to get. I rush in. I buy it. I 2 ." Common wisdom says that guys hate to shop. You can ask generations of men. But people who study shopping say that a number of social, cultural and economic factors are now 3 this "men-hate-to-shop" notion. " 4 social class and age, men say they hate to shop," says Sharon Zukin, a City University of New York sociology professor. Yet when you ask them deeper questions, it turns out that they 5 to shop. Men generally like to shop for 6 , music and hardware (硬件). But if you ask them about the shopping they do for books or music, they"ll say, "Well, that"s not shopping. That"s 7 ." In other words, what men and women call "buying things" and how they approach that task are 8 . Women will 9 through several 1,000-square-metre stores in search of the perfect party dress. Men will wander through 100 Internet sites in search of the 10 digital camcorder (摄像放像机). Women see shopping as a social event. Men see it as a mission or a 11 to be won. "Men are frequently shopping to win," says Mary Ann McGrath, a marketing professor at Loyola University of Chicago. "They want to get the best deal. They want to get the best one, the last one and if they do that it 12 them happy." When women shop, "they"re doing it in a way where they want 13 to be very happy," says McGrath. "They"re kind of shopping for love." In fact, it is in clothing where we see a male-female 14 most clearly. Why, complain some men, are all male clothes navy, black or brown? But would they wear light green and pink (粉红色的)? These days, many guys wear a sort of "uniform", says Paco Underhill, author of "Why We Buy". "It"s been hard for them to understand what it means to be fashion-conscious (时尚意识) in a business way. It becomes much, much easier 15 you narrow your range of choices."

单选题Difficult to Have Hard Discoveries If there is one thing scientists have to hear, it is that the game is over. Raised on the belief of an endless voyage of discovery, they recoil (畏缩) from the suggestion that most of the best things have already been located. If they have, today"s scientists can hope to contribute no more than a few grace notes to the symphony of science. A book to be published in Britain this week, The End of Science, argues persuasively that this is the case. Its author, John Horgan, is a senior writer for Scientific American magazine, who has interviewed many of today"s leading scientists and science philosophers. The shock of realizing that science might be over came to him, he says, when he was talking to Oxford mathematician and physicist Sir Roger Penrose. The End of Science provoked a wave of denunciation (谴责) in the United States last year. "The reaction has been one of complete shock and disbelief," Mr. Horgan says. The real question is whether any remaining unsolved problems, of which there are plenty, lend themselves to universal solutions. If they do not, then the focus of scientific discovery is already narrowing. Since the triumphs of the 1960s—the genetic code, plate tectonics (板块构造学说), and the microwave background radiation that went a long way towards proving the Big Bang —genuine scientific revolutions have been scarce. More scientists are now alive, spending more money on research, than ever. Yet most of the great discoveries of the 19th and 20th centuries were made before the appearance of state sponsorship, when the scientific enterprise was a fraction of its present size. Were the scientists who made these discoveries brighter than today"s? That seems unlikely. A far more reasonable explanation is that fundamental science has already entered a period of diminished returns. "Look, don"t get me wrong," says Mr. Horgan. "There are lots of important things still to study, and applied science and engineering can go on forever. I hope we get a cure for cancer, and for mental disease, though there are few real signs of progress. "

单选题Improve Computer-research Skills Like many college students, Jose Juarez carries around a pocket-sized computer that lets him watch movies, surf the Internet and text—message his friends. He's part of "Generation M" — those born after 1985 who (51) up connected to everything from video game to cellphones. "For us, it's everyday life," said Juarez, 18, a freshman (52) California State University at Sacramento (CSUS). (53) , educators are now saying that not all Generation M-ers can synthesize the piles of in- formation they're accessing. "They're geeky, but they don't know what to (54) with their geekdom(滑稽)," said Barbara O'Connor, a Sacramento State communications studies professor who has been involved in a nationwide (55) to improve students' computer-research skills. In a recent nationwide test to (56) their technological "literacy" — their ability to use the Internet to complete class assignments — only 49 percent correctly evaluated a set of Web sites for objectivity , authority and timeliness (合时) . Only 35 per cent could correctly narrow an overly (57) Internet search. About 130 Sacramento State students, including Juarez, participated in the experimental test, (58) to 6,300 college students across the country. The hour-long assessment test is conducted by Educational Testing Service. It is a web-based scavenger hunt (拾荒游戏) (59) simulated Internet search engines and academic databases that spit out purposely misleading information. "They're very good a (60) in and using the Internet, but don't always understand what they get back," said Linda Golf, head of instructional services for the CSUS library. "You see an open search box, you type in a few words and you (61) the button," said Golf, who is involved in the testing. "They take at face value (62) shows up at the top of the list as the best stuff." Educators say that these sloppy research skills are troubling. "We look at that as a foundational skill, in the same way we (63) math and English as a foundational skill," said Lorie Roth, assistant vice-chancellor for academic programmes in the CSU system. Measuring how well students can "sort the good (64) the bad" on the Internet has become a higher priority for CSU, Roth said. CSU is considering (65) a mandatory assessment test on technological literacy for all freshmen, much as it has required English and math placement tests since the 1980s. Students in freshman seminars at Sacramento State were asked to take the test early in the semester and were expected to finish another round this week to measure their improvement.
