1、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. The designers of the VLT are surprised at____. 【单选题】

A.its detecting power

B.millions of light years away in space

C.the location of the VLT

D.as an example

E.the birth of the earth

F.the rotation of the earth

正确答案:A

答案解析:文章第2段最后一句也概括提到了这句话的意思。

2、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 ｏｒother kinds of materials could one day contain a colｏｒswitching material. It will turn red before a structure collapses ｏｒfalls apart. The secret behind the colｏｒswitching material is a particular type of molecule. A molecule is aｇｒｏｕｐof atoms held together by chemical bonds. Molecules come at 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 colｏｒswitching molecule called a mechanophore (机械响应性聚合物) which is about to break, it produce 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 colｏｒswitching polymers in their lab. The test results proved encouraging. There is a way to get rid of the colｏｒlight when a bright light is shone on the mechanophore. The broken bond is fixed ａｎｄ　the red colｏｒdisappears. This "self-healing" may be a problem fｏｒengineers. They need to use the colｏｒchanger in big construction projects that will be outside in sunlight. ａｎｄ　sunlight will make the mechanophore\'s warming system ______. Sottos ａｎｄ　her fellow scientists still have a lot of work to do before the colｏｒswitching molecules can be used outside the lab. 【单选题】

A.dangerous

B.useless

C.helpful

D.important

正确答案:B

答案解析:前后文是转折关系，前面说到是问题，又有warning system的说法，应该是使之失效的意思，选useless。

3、She gave up her job ａｎｄ　started writing poetry.【单选题】

A.abandoned

B.lost

C.took

D.created

正确答案:A

答案解析:她辞去工作，开始写诗。本题难度不大，gave up是常用短语，指“放弃，辞职”，和abandoned“放弃”是近义词，其他三项都是常用词，和答案意义差异较大，干扰性不强。答案是A。

4、The SmogFｏｒover a month, Indonesia was in crisis. Forest fires raged out of control as the country suffered its worst drought fｏｒ50 years. Smoke from the fires mixed with sunlight ａｎｄ　hot dry air to form a cloud of smog. This pollution quickly spread ａｎｄ　within days it was hanging over neighboring countries including Malaysia, Singapore ａｎｄ　Thailand. When the smoke combined with pollution from factories ａｎｄ　cars, it soon became poisonous. Dangerous amounts of CO became trapped under the smog ａｎｄ　pollution levels rose. People wheezed (喘息) ａｎｄ　coughed as they left the house ａｎｄ　their eyes watered immediately. The smog made it impossible to see across streets ａｎｄ　whole cities disappeared as grey soot(烟灰) covered everything. In some areas, water was hosed (用胶管浇) from high-rise city buildings to try ａｎｄ　break up the smog. Finally, heavy rains, which came in November. Put out the fires ａｎｄ　clear the air. But the environmental costs ａｎｄ　health problems will remain. Many people from South-Eastern Asian cities already suffer from breathing huge amounts of car exhaust fumes ａｎｄ　factory pollution Breathing problems could well increase ａｎｄ　many non-sufferers may have difficulties fｏｒthe first time. Wildlife has suffered too. In lowlａｎｄ　forests, elephants, deer, ａｎｄ　tigers have been driven out of their homes by smog. But smog is not just an Asian problem. In fact. was world was first used in London in 1905 to describe the mixture of smoke ａｎｄ　thick fog. Fog often hung over the capital. Sometimes the smog was so thick ａｎｄ　poisonous that people were killed by breathing problems ｏｒin accidents. About 4, 000 Londoners died within five days as a result of thick smog in 1952. The smog spread to neighboring countries. 【单选题】

A.Right

B.Wrong

C.Not mentioned

正确答案:A

答案解析:题句的意思是“烟雾飞散到临近国家”。与第1段第3句意思相同，故选A。
