1、阅读下列四篇短文,从每小题后所给的A,B,C或D四个选项中,选出最佳选项。As the railroads and the highways shaped the American West in the past centuries, a new electrical generating (发电) and transmission (输送) system for the 21st century will leave a lasting mark on the West, for better or worse. Much of the real significance of railr
2、oads and highways is not in their direct physical effect on the scenery, but in the ways that they affect the surrounding community. The same is true of big solar plants and the power lines that will be laid down to move electricity around.The 19th century saw land grants (政府拨地) offered to railroad
3、companies to build the transcontinental railroads, leaving public land in between privately owned land. In much of the west, some of the railroad sections were developed while others remained undeveloped, and in both cases the landownership has presented unique challenges to land management. With th
4、e completion of the interstate highway system, many of the small towns which sprang up as railway stops and developed well, have lost their lifeblood and died.Big solar plants and their power lines will also have effects far beyond their direct footprint in the West. This is not an argument against
5、building them. We need alternative energy badly, and to really take advantage of it we need to be able to move electricity around far more readily than we can now.So tradeoffs will have to be made. Some scenic sports will be sacrificed. Some species (物种) will be forced to move, or will be carefully
6、moved to special accommodations. Deals will be struck to reduce the immediate effects.The lasting effects of these tradeoffs are another matter. The 21st century development of the American West as an ideal place for alternative energy is going to throw off a lot of power and money in the region. Th
7、ere are chances for that power and money to do a lot of good. But it is just as likely that they will be spent wastefully and will leave new problems behind, just like the railroads and the highways.The money set aside in negotiated tradeoffs and the institution that control it will shape the West f
8、ar beyond the immediate footprint of power plants and transmission lines. So lets remember the effects of the railroads and the highways as we construct these new power plants in the West.本文是一篇说明文。19世纪,美国政府拨款修建铁路和公路,这既带来了好处,也带来了一些不利。现在21世纪,一种新型的电力系统会给美国带来好处还是坏处,这是值得考虑的一个问题。在建这种新型的电力系统时,我们要记住铁路和公路的影响

Land in the West was hard to manage.D. Land grants went into private hands.答案:C。细节理解题。根据第二段的“.and in both cases the landownership has pres
10、ented unique challenges to land management.”可知,建铁路导致的问题是“土地所有权给土地管理带来了挑战”。A项是修建公路的影响;B项说一些铁路站一直未被充分利用,是错误的;D项原文未说。2What is the major concern in the development of alternative energy according to the last two paragraphs?A. The transmission of power. B. The use of money and power.C. The conservation o
11、f solar energy. D. The selection of an ideal place. 答案:B。推理判断题。细读最后两段可知,对于可替代能源的发展主要的担忧是钱和力,钱和力可能带来一些好处,有可能被浪费掉,并且带来一些其他的问题。3What is the authors attitude towards building solar plants?A. Cautious. B. Approving. C. Doubtful. D. Disapproving.答案:A。推理判断题。根据全文以及文章的最后一句话“So lets remember the effects of th
12、e railroads and the highroads as we construct these new power plants in the West.”可知,对正在建立新的电力系统是比较谨慎的。4Which is the best title for the passage?A. How the Railways Have Affected the WestB. How Solar Energy Could Reshape the WestC. How the Effects of Power Plants Can Be ReducedD. How the Problems of
13、the Highways Have Been Settled答案:B。主旨大意题。文章借助于铁路和公路对美国的影响,要说明的是太阳能这种新的电力系统对美国西部地区会有什么的影响。阅读下列四篇短文,从每小题后所给的A,B,C或D四个选项中,选出最佳选项。The 2012 London Olympics had enough problems to worry about. But one more has just been addeda communications blackout caused by solar storms.After a period of calm within th
14、e Sun,scientists have detected the signs of a fresh cycle of sunspots that could peak in 2012,just in time for the arrival of the Olympic torch in London.Now scientists believe that this peak could result in vast solar explosions that could throw billions of tons of charged matter towards the Earth,
15、causing strong solar storms that could jam the telecommunications satellites and internet links sending live Olympic broadcast from London.“The Suns activity has a strong influence on the Earth. The Olympics could be in the middle of the next solar maximum which could affect the functions of communi
16、cations satellites,“ said Professor Richard Harrison,head of space physics at the Rutherford Appleton Laboratory in Oxfordshire.At the peak of the cycle,violent outbursts calledcoronal mass ejections(日冕物质抛射) occur in the Suns atmosphere,throwing out great quantities of electrically-charged matter. “
17、A coronal mass ejection can carry a billion tons of solar material into space at over a million kilometres per hour. Such events can expose astronauts to a deadly amount,can disable satellites,cause power failures on Earth and disturb communications,” Professor Harrison added. The risk is greatest d
18、uring a solar maximum when there is the greatest number of sunspots.Next week in America,NASA is scheduled to launch a satellite for monitoring solar activity called the Solar Dynamics Observatory(SDO),which will take images of the Sun that are 10 times clearer than the most advanced televisions ava

26、stles (刚毛) on each foot that adds friction (摩擦) and static adsorption (静电吸附力) that makes a lizard move on the smooth wall easily without falling down. Then scientists made great efforts to fix thick bristles to the robots hands and feet. However, the effect was not satisfactory. The robot still coul
27、dnt attach itself firmly to the wall. Scientists got puzzled: How on earth can the lizard crawl on an extremely smooth wall or even on a ceiling without dropping off? An accidental finding inspired them: One day a scientist happened to see an animal attack a lizard and bite off its tail. The lizard
28、broke away from the animals teeth and threw itself on a wall to escape, only to fall off heavily on the ground. The scientist wondered: Is it the tail that plays an important role in its travelling on the wall? He caught some lizards for an experiment. The result proved his assumption: A tailless li
29、zard has no trouble walking on an ordinary wall but cant on a smooth one. A further study showed the lizards tail can prevent it falling over backward and, whats more, that the tail acts as an additional leg while one of the lizards legs leaves the wall, which is always the case while it is walking
30、on the wall. Thus, Tailbot, a super tailed robot, is born. 49. What part(s) would be a must if scientists just wanted a robot which can hang on the wall? A. Suckers.B. Suckers and bristles.C. Suckers, bristles and a tail.D. Hands, feet, bristles and a tail. 50. The bristles function as something _.
