1、托福-练习十一及答案解析(总分:38.00,做题时间:90 分钟)一、Passage 1(总题数:1,分数:12.00)Gadgets with a Sporting ChanceConsumer electronics: New sports equipment, from tennis rackets to running shoes, uses processing power to enhance performance. Is that fair? Why should aspiring athletes stand on the sidelines when a spot of e
2、lectronic assistance can put them in the middle of the game? That is the question many sports-equipment makers are asking as they sense an opportunity to boost their sales with high-tech products. You could call it the revenge of the nerds: a new wave of microchip-equipped sporting goods promises to
3、 enhance the performance of novices and non-sporting types alike-and could even make difficult sports easier.Take cross-country skiing. Victor Petrenko, an engineer at Dartmouth Colleges Ice Research Lab in New Hampshire, has invented some smart ski-brakes that, he believes, will increase the popula
4、rity of cross-country skiing by making the sport less challenging for beginners. The brakes, currently being tested by a ski manufacturer in the Alps, offer the necessary friction for a bigger “kick-off force“ and make the skis less likely to slide backwards in their tracks. To make this happen, an
5、electric current from the bottom of the skis pulses through the ice, melting a thin layer of snow that instantly refreezes and acts as a sort of glue.This is not the only form of smart ski to hit the slopes. Atomic, a leading ski-maker based in Austria, plans to introduce a system later this year th
6、at runs a diagnostic safety check to ensure that the ski binding is properly closed, with the result being shown on a tiny built-in liquid-crystal display. Meanwhile, tennis equipment manufacturers are hoping that innovation will bring new zip to their business as well. They certainly need to do som
7、ething: according to Sportscanlnfo, a market-research firm based in Florida, sales of tennis rackets in America fell 12.5% during the first half of 2004 compared with the first half of 2003.With the ball clearly in their court, researchers at Head, a maker of sporting equipment, have devised a produ
8、ct that should appeal to players suffering from tennis elbow. A chip inside the racket controls piezo-electric fibres, which convert mechanical energy from the balls impact into electrical potential energy. This energy is then used to generate a counter-force in the piezo-electric fibres that causes
9、 a dampening effect. All of this, the firm says, translates into less stress on the elbow. Head claims that residual vibrations in the racket are dampened twice as fast as in conventional rackets, reducing the shock experienced by the players arm by more than 50%.No doubt purists will object that th
10、is is simply not cricket. Rule-makers in many sports are now being forced to consider the implications of equipment that promises to augment athletes performance with electronic muscle. The International Tennis Federation, that body is responsible for setting the rules of the game, has specified in
11、its most recent guidelines that “no energy source that in any way changes or affects the playing characteristics of a racket may be built into or attached to a racket“.Yet despite such wording, the guideline does not actually eliminate the use of Heads smart rackets, because there is no external ene
12、rgy source-the damping effect relies solely on energy from the balls impact. Though high-tech equipment may cause controversy on the court, tennis clubs have to adhere to the guidelines set for the sport, explains Stuart Miller, the ITFs technical manager. And if the rules allow self-generated force
13、s to modify a rackets response, so be it.Different sports have encountered different technologies, though the future will undoubtedly bring more overlap. In golf, gadgets that pinpoint the location of the green using the Global Positioning System (GPS). The rule-making body of the Royal and Ancient
