Calculate for a moment what could be done with even a part of those hours. Five thousand hours, I am told, are what a typical college undergraduate spends working on a bachelor's degree. In 10,000 hours you could have learned enough to become an astronomer or engineer. You could have learned several languages fluently. If it appealed to you, you could be reading Homer in the original Greek or Dostoyevsky in Russian. If it didn't, you could have walked around the world and written a book about it. The trouble with television is that it discourages concentration. Almost anything interesting and rewarding in life requires some constructive, consistently applied effort. The dullest, the least gifted of us can achieve things that seem miraculous to those who never concentrate on anything. But Television encourages us to apply no effort. It sells us instant gratification(满意). It diverts us only to divert, to make the time pass without pain. Television's variety becomes a narcotic(麻醉的), nor a stimulus. Its serial, kaleidoscopic (万花筒般的)exposures force us to follow its lead. The viewer is on a perpetual guided tour: 30 minutes at the museum, 30 at the cathedral, 30 for a drink, then back on the bus to the next attraction—except on television., typically, the spans allotted arc on the order of minutes or seconds, and the chosen delights are more often car crashes and people killing one another. In short, a lot of television usurps(篡夺;侵占) one of the most precious of all human gifts, the ability to focus your attention yourself, rather than just passively surrender it. Capturing your attention—and holding it—is the prime motive of most television programming and enhances its role as a profitable advertising vehicle. Programmers live in constant fear of losing anyone's attention—anyone's. The surest way to avoid doing so is to keep everything brief, not to strain the attention of anyone but instead to provide constant stimulation through variety, novelty, action and movement. Quite

第1篇 Teamwork Teamwork is just as important in science as it is on the playing field or in the gym. Scientific investigations are almost always carried out by teams of people working together. Ideas are shared, experiments are designed,data are analyzed, and results are evaluated and shared with other investigators. Group work is necessary, and is usually more productive than working alone. Several times throughout the year you may be asked to work with one or more of your classmates. Whatever the task your group is assigned, a few rules need to be followed to ensure a productive and successful experience. What comes first is to keep an open mind, because everyone's ideas deserve consideration and each group member can make his or her own contribution. Secondly, it makes a job easier to divide the group task among all group members. Thirdly, always worktogether, take turns, and encourage each other by listening, clarifying, and trusting one another. Mutual support and trust often make a great difference. Useful words and expressions: playing field n. 运动场 productive adj. 多产的，有生产价值的 productive force 生产力 productive labor 有价值的劳动 a productive farm 肥沃的农场 a productive writer 多产作家 investigation n. 调查，研究 (be) under investigation 在调查研究中 bear investigation 经得起考查，不怕追查 keep an open mind 不抱成见，抱着虚心态度 make a great difference 有很大差别，有很大影响 听力源文件下载地址：https://www.wendangku.net/doc/0f4210957.html,/s/1i3iV5Tb

Fixing a World That Fosters Obesity Environment forstering obesity Why are Americans getting fatter and fatter? The simple explanation is thatwe eat too much junk food and spend too much time in front of screens--be they television, phone or computer-to burn off all those empty calories. One handy prescription for healthier, lives is behavior modification. If people only ate more fresh produce. If only children exercised more. Unfortunately, behavior changes won’t work on their own without huge societal shifts, health experts say, because eating too much and exercising too little are merely symptoms of a muchlarger disease. The real problem is a landscape littered with inexpensive fast—food meals；much advertisingfor fatty, sugary products; inner cities that lack supermarkets; and unhealthy, high—stress workplaces. In other words, it’s the environment. “Everyone knows that you shouldn’t eat junk food and you should exercise,” says Kelly D. Brownell, the director of the Rudd Center for Food Policy and Obesity at Yale. “But the environment makes it so difficult that fewer people can do these things, and then you have a public health catastrophe.” Dr. Brown ell, who has a doctorate in psychology, is among a number of leading researchers who are proposing large-scale changes to food pricing, advertising and availability, all in the hope of creating an environmentfavorable to healthier diet and exercise choices. To that end, health researchers are grappling with how to fix systems that are the root causes of obesity, says Dee W. Edington, the director of the Health Management Research Center at the University of Michigan. “If you take a changed person and put them in the same environment, they are going to go back to the old behaviors,” says Dr. Edington, who has a doctorate in physical education. “If you change the culture and the environment first, then you can go back into a healthy environment and, when you get change, it sticks.” Indeed, despite individual efforts by. some states：to tax soda pop, promote farm stands, require healthier school lunches or order calorie information in chain restaurants, obesity rates in the United States are growing. An estimated 72.5 million adults in the United States are obese, according to the Centers for Disease Control and

大学英语四级考试模拟试卷及参考答案(第一套)

大学英语四级考试模拟试卷及参考答案(第 一套） Part II Reading Comprehension (35 minutes) Directions: There are 4 reading passages in this part. Each passage is foll owed by some questions or unfinished statements. For each of them there are fou r choices marked A), B), C) and D). You should decide on the best choice and ma rk the corresponding letter on the Answer Sheet with a single line through the center. Passage One Questions 21 to 25 are based on the following passage. There is a difference between science and technology. Science is a method o f answering theoretical questions; technology is a method of solving practical problems. Science has to do with discovering the facts and relationships betwee n observable phenomena in nature and with establishing theories that serve to o rganize these facts and relationships; technology has to do with tools, techniq ues, and procedures for implementing the finding of science. Another distinction between science and technology has to do with the progr ess in each. Progress in science excludes the human factor. Scientists, who seek to comp rehend the universe and know the truth within the highest degree of accuracy an d certainty, cannot pay attention to their own or other people's likes or disli kes or to popular ideas about the fitness of things. What scientists discover m ay shock or anger people-as did Darwin's theory of evolution. But even an unple asant truth is more than likely to be useful; besides, we have the choice of re fusing to believe it! But hardly so with technology; we do not have the choice

As a manager, Tiffany is responsible for interviewing applicants for some of the positions with her company .During one interview, she noticed that the candidate never made direct eye contact. She was puzzled and somewhat disappointed because she liked the individual otherwise. He had a perfect resume and gave good responses to her questions, but the fact that he never looked her in the eye said “untrustworthy,” so she decided to offer the job to her second choice. “It wasn’t until I attended a diversity workshop that I realized the person we passed over was the perfect person,” Tiffany confesses. What she hadn’t known at the time of the interview was that the candidate’s “different” behavior was simply a cultural misunderstanding . He was an Asian-American raised in a household where respect for those in authority was shown by averting(避开) your eyes. “I was just thrown off by the lack of ye contact; not realizing it was cultural,” Tiffany says. “I missed out ,but will not miss that opportunity again.” Many of us have had similar encounters with behaviors we perceive as different. As the world becomes smaller and our workplaces more diverse, it is becoming essential to expand our under-standing of others and to reexamine some of our false assumptions . Hire Advantage At a time when hiring qualified people is becoming more difficult ,employers who can eliminate invalid biases(偏爱) from the process have a distinct advantage .My company, Mindsets LLC ,helps organizations and individuals see their own blind spots . A real estate recruiter we worked with illustrates the positive difference such training can make .
