1、Snow RangerThe two things, snow and mountains, which are needed fora ski area are the two things that cause avalanches, large mass of snow and ice crushing down the side of a mountain, often called "White Death. "It was the threat of the avalanche and its record as a killer of man in the western mountains that created the snow ranger. He first started on avalanche control work in the winter of 1937, 38 at Alta, Utah, in Wasatch National Forest. This mountain valley was becoming well known to skiers. It was dangerous. In fact, more than 120 persons had lost their lives in 1936 and another 200 died in 1937 as a result of avalanches before it became a majorski area. Thus, development of Alta and other majorski resorts in the west was dependent upon controlling the avalanche. The Forest Service setout to do it, and did with its corps of snow rangers. It takes many things to make a snow ranger. The snow ranger must be in excellent physical condition. He must be a good skier and a skilled mountain climber. He should have at least a high school education, and the more college courses in geology, physics, and related fields he has, the better. He studies snow, terrain, wind, and weather. He learns the conditions that produce avalanches. He learns to forecast avalanches and to bring them roaring on down the mountainsides to reduce their killing strength. The snow ranger learns to do this by using artillery, by blasting with TNT, and by the difficult and skillful art of skiing avalanches down. The snow ranger, dressed in a green parka which has a bright yellow shoulder patch, means safety forpeople on ski slopes. He pulls the trigger on a 75 mm. Recoilless rifle, skis waist deep in powder testing snow stability, ortalks with the ski area\'s operatoras he goes about his work to protect the public from the hazards of deep snow on steep mountain slopes. A snow ranger uses very powerful guns____. 【单选题】
A.to warn skiers of an approaching avalanche.
B.to signal forhelp in an emergency.
C.to create an avalanche.
D.to communicate with the ski area operator.
正确答案:C
答案解析:这道题可以依据线索词在句中寻找答案。线索词:powerful gun(很强杀伤力的枪)或与其近义的短语。在第6段最后一句中发现gun的近义词artillery,找到了答案相关句。该句的前一句说“雪地管理员要使雪崩沿着山坡轰隆隆地滚下”,所以答案是C:制造雪崩。
2、Arctic MeltEarth\'s North and South Poles are famous forbeing cold and icy. Last year, however, the amount of ice in the Arctic Ocean (北冰群) fell to a record low.Normally, ice builds in Arctic waters around the North Pole each winter and shrinks(缩小) during the summer. But formany years, the amount of ice left by the end of summer has been declining.Since 1979, each decade has seen an 11.4 percent drepin end of summer ice cover. Between 1981 and 2000, ice in the Arctic lost 22 percent of its thickness, becoming 1.13 meters thinner.Last summer, Arctic sea ice reached its thinnest levels. By the end of summer 2007, the ice had shrunk to cover just 4.2 million square kilometers. That\'s 38 percent less area than the average cover at that time of year. and it\'s a very large 23 percent below the previous record low, which was setjust 2 years ago. This continuing trend has made scientists concerned to.There may be several reasons forthe ice melt, says Jinlun Zhang, an oceanographer (海洋学家)at the University of Washington in Seattle. Unusually strong winds blew through the Arctic last summer. The winds pushed much of the ice out of the central Arctic, leaving a large area of thin ice and open water.Scientists also suspect that fewer clouds cover the Arctic now than in the past. Clearer skies allow more sunlight to reach the ocean. The extra heat warms both the water and the atmosphere. In parts of the Arctic Ocean last year, surface temperatures were 3.57 Celsius warmer than the average and 1.5c warmer than the previous record.With both air and water getting warmer, the ice is melting from both above and below. In some parts of the Beaufort Sea, north of Alaska and western Canada, ice that measured 3.3 meters thick at the beginning of the summer was measured just 50 cm by season\'s endThe new measurements suggest that melting is far more severe than the thinking of scientists. Some scientists fear that the Arctic is stuck in a warming trend.The Beaufort Sea mentioned in paragraph 7 is an example to show ______.【单选题】
A.how accurate the new measurements are
B.how thick the ice is in it
C.how serious the problem of the ice melt in the Arctic is
D.how dangerous it is to travel to it
正确答案:C
答案解析:本题难度不大,答案依据比较明显,文章第七段和第八段谈到,夏天冰层以超出科学家预料的速度迅速融化,答案是C。
3、What Is the Coolest Gas in the Universe?What is the coldest air temperature ever recorded on the Earth? Where was this low temperature recorded? The coldest recorded temperature on Earth was - 91℃, which occurred in Antarctica (南极洲) in 1983.We encounter an interesting situation when we discuss temperatures in space.Temperatures in Earth orbit actually range from about +120℃ to - 120℃. The temperature depends upon whether you are in direct sunlight orshade. Obviously, -120℃ is colder than our body can safely endure. Thank NASA science forwell, de signed space suits that protect astronauts from these temperature extremes.The space temperatures just discussed affect only our areal of the solar system. Obviously, it is hotter closer to the Sun and colder as we travel away from the Sun. Astronomers estimate temperatures at Pluto are about - 210℃. How cold is the lowest estimated temperature in the entire universe? Again, it depends upon your location. We are taught it is supposedly impossible to have a temperature below absolute zero, which is - 273℃, at which atoms do not move. Two scientists, whose names are Cornell and Wieman, have successfully cooled down a gas to a temperature barely above absolute zero. They won a Nobel Prize in Physics in 2001 fortheir work, not a discovery, in this case.Why is the two scientists\' work so important to science?In the 1920s, Satyendra Nath Bose was studying an interesting theory about special light particles we now call photons (光子). Bose had trouble convincing other scientists to believe his theory, so he contacted Albert Einstein. Einstein\'s calculations helped him theorize that atoms would behave as Bose thought—but only at very cold temperatures.Scientists have also discovered that ultra - cold(超冷) atoms can help them make the world\'s atomic clocks even more accurate. These clocks are so accurate today they would only lose one second ______ six million years! Such accuracy will help us travel in space because distance is velocity times time 4 ( d = v×t). With the long distances involved in space travel, we need to know time as accurately as possible to get accurate distance.【单选题】
A.any
B.each
C.some
D.every
正确答案:D
答案解析:本题有一定难度,考查不定代词every的用法,干扰项有一定的干扰。根据上下文逻辑,文章此处是说“……每六百万年仅差一秒”,each后面不能跟复数名词,因此最佳答案是D。

The new measurements suggest that melting is far more severe than scientists have seen by just looking at ice cover from above, says Donald K. Perovich, a geophysicist at the U. S. Army Cold Regions Research and Engineering Laboratory in Hanover, N. H. Some scientists fear that the Arctic is stuck in a warming trend from which it may never recover. What are the reasons forthe ice melting according to the scientists?【单选题】
A.strong winds and clear skies
B.long summer and short winter
C.open water and thin ice
D.light clouds and light winds
正确答案:A
答案解析:第5段最后一句和第6段第1句、第2句说明了科学家们推测的冰川融化原因:一为强风;二为较少的云,即clear skies。
5、Seeing Red Means Danger AheadThe colorred often means danger and by paying attention, accidents can be prevented. In the future, the colorred also may help prevent danger at construction sites. Thanks to new work by engineers, bridge supports or_____ kinds of materials, could one day contain a color- changing material. It will turn red before a structure collapses orfalls apart.The secret behind the color- changing material is a particular type of molecule (分子). A molecule is agroupof atoms (原子) held together by chemical bonds. Molecules come in all shapes and sizes and make up everything you can see, touch orfeel. How a molecule behaves depends on what kinds of atoms it contains and how they\'re held together.When a polymer (聚合物) containing a color- changing molecule called a mechanophore (机械响应性聚合物) is about to break, it produces a color. When a polymer with mechanophore molecules becomes "injured" orweak, one of the mechanophore bonds breaks and the material turns red. "It\'s a really simple detection method," says Nancy Sottos, one of the scientists who worked on the project. Sottos and her team tested the color- changing polymers in their lab. The test results proved encouraging.There is a way to get rid of the red colorlight. When a bright light is shone on the mechanophore, the broken bond is fixed and the red colordisappears. Thus "self - healing" may be a problem forengineers. They need to use the color- changer in big construction projects that will be outside, under sunlight. and sunlight will make the mechanophore\'s warning system useless.Sottos and her fellow scientists still have a lot of work to do before the color- changing molecules can be used outside the lab.【单选题】
A.other
B.another
C.the other
D.others
正确答案:A
答案解析:本题有一定难度,干扰项干扰较大,考查不定代词other的用法,other kinds of是固定搭配,这个搭配里只能用other的单数答案是A。
6、Don\'t Rely on Plankton to Save the PlanetEncouraging plankton growth in the ocean has been touted by some as a promising way to remove carbon dioxide from the atmosphere. ______Adding iron to patched of ocean can make plankton bloom temporarily. The microscopic organisms suck up dissolved carbon dioxide from the water, which in turn is replaced by carbon dioxide from the air. As plankton die and settle on the ocean floor, their carbon is supposedly locked up in the seabed.Jorge Sarmiento from Princeton and his colleagues developed a complex computer model to analyze how factors such as ocean chemistry and water circulation would affect the process if 160,000 square kilometers of ocean were seeded with iron fora month. They found that 100 years later only between 2 and 13 percent of the extra carbon that was originally taken up plankton had actually been removed from the atmosphere.In their scenario, which covers an area 10 times as big as the largest experiment of this kind ever proposed, fertilizing the ocean removes 1 million tons of carbon from the atmosphere just 0.2 percent of the carbon dioxide humankind spews out each month. Rough estimates in the past have predicted similarly disappointing results."These are newer and better models," says Sallie Chisholm, an environmental engineer from the Massachusetts Institute of Technology."Butthe take-home message is the same. Ocean fertilization is not the answer to global warming."【单选题】
A.Its opponents argue, however, that it will stop global warming.
B.Its opponents fear that will damage the marine ecosystem, and now a computer model shows that the trick would also be remarkably inefficient.
C.As plankton die and settle on the ocean floor, their carbon is supposedly locked up in the seabed.
D.They found that 100 years later only between 2 and 11 percent of the extra carbon that was originally taken up plankton had actually been removed from the atmosphere.
E."These are newer and better models,"
F.Ocean fertilization is not the answer to global warming.
正确答案:B
答案解析:前句的句意(可以直接借助句子中的核心结构判断句子大意):“一些人鼓励浮游生物在海洋里生长,认为这有希望从大气中去除二氧化碳”,B中的opponents fear和空白前句中的some. . . encourage形成语意对比。

9、An Intelligent CarDriving needs sharp eyes, keen ears, quick brain, and coordination between hands and the brain. Many human drivers have all. these and can control a fast-moving car. But how does an intelligent car control itself ?There is a virtual driver in the smart car. This virtual driver has "eyes," "brains", "hands" and "feet", too. The mini-cameras on each side of the car are his "eyes," which observe the road and conditions ahead of it. They watch the traffic to the car\'s left and right. There is also a highly automatic driving system in the car. It is the built-in computer, which is the virtual driver\'s "brain". His "brain" calculates the speeds of other moving cars near it and analyzes their positions. Basing on this information, it chooses the right line forthe intelligent cars, and gives ______ to the "hands" and "feets" to act accordingly. In this way, the virtual driver controls his car. What is the virtual driver\'s best advantage? He reacts rapidly. The mini-cameras are sending images continuously to the "brain". It completes the processing of the images within 100 milliseconds. However, the world\'s best driver at least needs one second to react. Besides, when he takes action, he needs one more second. The virtual driver is really wonderful. He can reduce the accident rate. considerably on expressway. In this case, can we let him have the wheel at any time and in any place? Experts warn that we cannot do that just yet. His ability to recognize things is still limited. He can now only drive an intelligent car on expressways. 【单选题】
A.space
B.locations
C.instructions
D.time
