1、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.What may be some of the reasons fｏｒthe ice melt in the Arctic? ______【单选题】

A.Unusually strong winds ａｎｄ　clearer skies.

B.Heavy clouds ａｎｄ　light winds.

C.Longer summers ａｎｄ　shorter winters.

D.Thin ice ａｎｄ　open water.

正确答案:A

答案解析:本题有一定的难度，但答案依据还是比较明显，不过跨越了两个段落，文章第五段谈到去年有强风刮过北极，第六段谈到科学家怀疑云层少了，所以答案是A。

2、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 instructions 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 ______. He can now only drive an intelligent car on expressways. 【单选题】

A.unknown

B.few

C.untested

D.limited

正确答案:D

答案解析:空白所在的句子说“他识别不同东西的能力仍然还……”，空白后句说“他现在只能驾驶智能车在高速路上行驶”。既然能在高速路上行驶，则其应该具备一定识别物体的能力，而且应该已经经过检测，因此排除A（未知的）和C（未经试验的）；few应该修饰可数名词的复数形式，而句子主语（被修饰词）是单数，因此排除B，答案是D（有限的）。

3、A Star Is Born1 The VLT (Very Large Telescope) is the world\'s largest telescope ａｎｄ　is taking astronomers further back to the Big Bang than they ever thought possible. Located 2,600 meters up to the Chilean Andes, it has four huge mirrors, each about the size of a London bus. The VLT is so powerful it can spot a burning match 10, 000 kilometers away. 2 This astonishing power will allow astronomers to see events in space from the birth of stars to the collision of galaxies on the edge of the cosmos. The VLT is giving astronomers their best ever view of the cosmos. The power of the VLT to see the smallest detail at the furthest distances makes its designers amazed. 3 Take the case of Eta Carinae, one of the most explosive stars in the universe. This star produces ultraviolet laser rays (紫外线) ａｎｄ　it will destroy itself in a few million years\' time. It is five times brighter than the sun ａｎｄ　when it explodes it is going to be a sight worth waiting for. 4 But it is at distances of millions, even billions, of light years that the VLT really shows its power. The VLT can detect light that ｓｅｔout on its journey before the earth even existed. This gives astronomers their first ever detailed views of events that took place in the earliest days of the cosmos. 5 In other words, the VLT is a kind of a time machine. It takes astronomers back to a time when complete galaxies crashed into each other. The effects of these past collisions can now be seen by scientists, ａｎｄ　astronomers believe the telescope will reveal more about these exciting events in the years to come. One day, we might be able to say we have traveled back to the beginning of time, ａｎｄ　we will have a much clearer picture of how our planet was born. Paragraph 4____【单选题】

A.Events That Took place Before the Earth Existed

B.Power of the Telescope

C.Details of Eta Carinae

D.Invention of a Time Machine

E.Biggest Telescope

F.Ultraviolet Laser Rays

正确答案:A

答案解析:文章第4段的主要意思体现在最后一句话里，选项A体现了这句话的意思，故为正确答案。

4、A research center has been ｓｅｔup in this country.【单选题】

A.praised
