Will Anyone Watch 3-D TV?Mark the calendar: 2010 might be the year that TVs final frontier gets broken. Announced in early September, the newest models in the offing (

8、马上就来临的) for late 2010 from Sony and Panasonic are bringing 3-D HDTV (高消晰度电视) into the home. That is, if youre willing to wear the glasses.Yes, glasses. Theyre not quite the flimsy red-and-blue-cellophane (玻璃纸) getups that they used to be, but the Sony and Panasonic models still require you to wear a

9、 pair of shades to observe the effect. How can TV manufacturers convince you that seeing shows in 3-D is worth the annoyance of having to wear a pair of specs (眼镜)?The first way is by making the technology way better. After all. 3-D entertainment is nothing new. The early 1950s were flooded with 3-D

10、 movies, and the technology has made an occasional comeback ever since. Each time, though, its done in by the same complaints: poor image quality and headaches and eyestrain from extended viewing. Early reviews of the new models from Sony and Panasonic suggest theyve solved the problem. Both use gla

11、sses that contain tiny shutters (快门), opening and closing at 120 frames per second, in sync with (与同步)the image on the screen to give the illusion of depth. Its a new approach that gives users a wider viewing angle, another weakness of older approaches.All this would be pointless if the entertainmen

12、t industry werent also taking a new look at 3-D, The recent spate (一阵) of 3-D movies on the big screen-G-Force, Monsters vs Aliens and My Bloody Valentine all had 3-D debuts this year-foreshadows (预示) a similar spurt on the small screen. Blu-ray discs, which have the storage capacity necessary for h

13、igh-definition 3-D content, and their players are becoming more affordable, and Panasonic is working with movie studios to release 3-D editions of movies, timed to coincide with the first group of TVs. Broadcast networks are paying close attention too-ESPN broadcast the Sept. 12 USC vs. Ohio State c

14、ollege-football game in 3-D as a pilot test. and in Britain there are already stations dedicated to 3-D content.But still. The glasses! The headgear(盔)necessary to watch modem 3-D TVs remains bulky-and, well, ugly-but Luxottica, maker of Ray-Ban, is working on a solution tot that. The company plans

All you ever do is eat. “ You feel sad: “I skip my breakfast and supper. I run eve

23、ry morning and evening. What else can I do?“ Basically you can do nothing. Your genes, not your life habits, determine your weight and your body constantly tries to maintain it.Albert Stunkard of the University of Pennsylvania found from experiments that, “80 percent of the Children of two obese par

24、ents become obese, as compared with no more than 14 percent of the offspring of two parents of normal weight. “How can obese people become normal or even thin through dieting? Well, dieting can be effective, but the health costs are tremendous. Jules Hirsch, a research physician at Rockefeller Unive

25、rsity, did a study of eight fat people. They were given a liquid formula providing 600 calories (卡路里) a day. After more than 10 weeks, the subjects lost 45 kg on average. But after leaving the hospital, they all regained. The results were surprising: by metabolic measurement, fat people who lost lar

26、ge amounts of weight seemed like they were starving. They had psychiatric problems. They dreamed of food or breaking their diet. They were anxious and depressed (沮丧的) ; some were suicidal. They hid food in their rooms. Researchers warn that it is possible that weight reduction doesnt result in norma

27、l weight, but in an abnormal state resembling (类似) that of starved non-obese people.Thin people, however, suffer from the opposite: They have to make a great effort to gain weight. Ethan Sims, of the University of Vermont, got prisoners to volunteer to gain weight. In four to six months, they ate as

28、 much as they could. They succeeded in increasing their weight by 20 to 25 percent. But months after the study ended, they were back to normal weight and stayed there.This did not mean that people are completely without hope in controlling their weight. It means that those who tend to be fat will ha

29、ve to constantly battle their genetic inheritance if they want to significantly lower their weight.The findings also provide evidence for something scientists thought was true - each person has a comfortable weight range. The range might be as much as 9 kg. Someone might weigh 60-69 kg without too m

30、uch effort But going above of below the natural weight range is difficult. The body resists by feeling hungry or full and changing the metabolism to push the weight back to the range it seeks.（分数：15.00）(1).What determines your weight?A. Your working manner. B. Your eating habit.C. Your life style. D

31、. Your genes.（分数：3.00）A.B.C.D.(2).What did Jules Hirsch do in his study?A. He let the eight fat people skip supper.B. He let the eight fat people skip breakfast.C. He let the eight fat people run every morning and evening.D. He gave the eight fat people a liquid formula providing 600 calories a day.

Each person wants to control his weight.D. Each person wants to eat to his hearts content.（分数：3.00）A.B.C.D.

34、六、第二篇(总题数：1，分数：15.00)Most of the pioneers of low-temperature physics expected gases to liquefy, but none of them predicted superconductivity. This phenomenon was discovered in 1911 by Onnes while he was studying frozen mercury.More than 40 years passed before physicists were able to offer an explana

35、tion for superconductivity. The accepted theory, developed in the 1950s, holds that the fundamental behavior of electrons changes at very low temperatures because of the effects of quantum mechanics. Electrons are tiny particles that make up the outer part of an atom, circling rapidly around the nuc

36、leus of the atom. In a regular conductora metal that conducts an electric currentthe outermost electrons are not bound tightly to the atoms, and so they move around relatively freely. The flow of these electrons is an electric current.At normal temperatures, a conductors electrons cannot move comple

37、tely freely through the metal because they are “bumped around“ by the metals atoms. But according to the leading theory of superconductivity, when a metal is very cold, electrons form pairs. Then, like couples maneuvering on a crowded dance floor but never colliding, the paired electrons are able to

38、 move unimpeded through the metal. In pairing up, it seems, the electrons are able to “blend together“ and move in unison without resistance.This explanation seems to account for superconductivity at extremely low temperatures, but in 1986 scientists in Switzerland found that some metal-containing c

39、eramics are superconductors at much higher temperatures. By 1992, scientists had developed ceramics that become superconducting at - 297F, and some researchers speculated that room-temperature superconductors may be possible. Scientists are still trying to formulate a theory for high-temperature sup

40、erconductivity.The new ceramic materials can be maintained at their superconducting temperatures, with relatively inexpensive liquid nitrogen rather than the much colder and much more costly liquid helium required by metal superconductors. The cost difference could make superconductivity practical f

41、or many new technologies. For example, magnetically levitated trains, which require superconducting electromagnets, would be much cheaper to build than they are now. Superconducting devices might also be used for advanced power transmission lines and in new types of compact, ultrafast computers. But

42、 for the time being, superconductivity is finding application mostly in scientific research and in some kinds of medical imaging devices.（分数：15.00）(1).The flow of an electric current in a regular conductor is made possible by the fact that_.A. electrons circle rapidly around the atomB. the outermost

43、 electron move relatively freely around the atomC. the innermost electrons stick to the atomD. the outermost electrons are bound tightly to the inner ones（分数：3.00）A.B.C.D.(2).At very low temperatures, superconductivity in a metal occurs where_.A. electrons do not move freely through the metalB. elec

44、trons are crowded togetherC. paired electrons move uninterruptedlyD. paired electron dance together to and fro（分数：3.00）A.B.C.D.(3).The word “bump“ in Paragraph 3 may mean _.A. to make something run fastB. to cause to revolveC. to move smoothlyD. to collide（分数：3.00）A.B.C.D.(4).The breakthrough made i

45、n superconductivity in 1992 is remarkable because _.A. metal-containing ceramics turned out to be superconductorsB. higher-temperature superconductivity was made possibleC. ceramics were found to be superconductorsD. room-temperature superconductors were developed（分数：3.00）A.B.C.D.(5).The best advant

46、age of new ceramic materials over metal superconductors is _.A. their inexpensive costB. their more practical usesC. their better quality in conductivityD. their nature for multi-application（分数：3.00）A.B.C.D.七、第三篇(总题数：1，分数：15.00)The Value of AdvertisementMoney spent on advertising is worth spending.

47、It serves directly to bring about a rapid sale of goods at reasonable prices, so setting up a firm home market and making it possible to provide for export at good price. By drawing attention to new ideas it helps greatly to raise standards of living. By helping to increase demand it causes an incre

48、ased need for labor, and is therefore a nice way to fight unemployment. It lowers the costs of many services: without advertisements your daily newspaper would cost four times as much, the price of your television program would need to be doubled, and travel by bus or subway would cost more.And perh

49、aps most important of all, advertising provides a promise of reasonable value in the products and services you buy. Besides the fact that twenty-seven Acts of Parliament govern the terms of advertising, no regular advertiser dare produce anything that fails to live up to the promise of his advertisements. He might fool some people for a little while through misleadin
