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. Paragraph 3____【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:C

答案解析:文章第3段介绍了Eta Carinae的情况，故C为正确答案。

2、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。

3、Easy ListeningStudents should be jealous. Not only do babies get to doze their days away, but they\'ve also mastered the fine art of learning in their sleep. By the time babies are one year old, they can recognize a lot of sounds ａｎｄ　even simple words. Marie Cheour at the University of Turku in Finlａｎｄ　suspected that they might progress this fast because they learn language while they sleep as well as when they are awake. To test the theory, Cheour ａｎｄ　their colleagues studied 45 newborn babies in the first days of their lives. They exposed all the infants to an hour of Finnish vowel sounds one that sounds like "oo"; another like "ee" ａｎｄ　the third boundary vowel peculiar to Finnish ａｎｄ　similar languages that sounds like something in between. EEG (脑电图) recording of the infants brains before ａｎｄ　after the session showed that the newborns could not distinguish the sounds. Fifteen of the babies then went back with their mothers, where the rest were split into two sleep-study groups. Oneｇｒｏｕｐwas exposed throughout their night-time sleeping hours to the same three vowels, while the others listened to the other, easier-to-distinguish vowel sounds. When tested in the morning, ａｎｄ　again in the evening, the babies who\'d heard the tricky boundary vowels all night showed brainwave activity indicating that they could now recognize this sound. They could identify the sound even when its pitch was changed, while none of the other babies could pick up the boundary vowel at all. Cheour doesn\'t know how babies accomplish this nighttime learning, but she suspects that the special ability might indicate that unlike adults, babies don\'t "turn off" their cerebral cortex (大脑皮层) while they sleep: The skill probably fades in the course of the first years of life, she adds so forget the idea that you can pick up the tricky French vowels as an adult just by slipping a language tape under your pillow. But while it may not help grown-ups, Cheour is hoping to use the sleeping hours to give remedial help to babies who are genetically at risk of language disorders. Babies can learn language even in their sleep. 【单选题】

A.Right

B.Wrong

C.Notmentioned

正确答案:A

答案解析:选A的依据是第2段最后一句。

4、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 _____ 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 every 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.would

B.will

C.must

D.need

正确答案:A

答案解析:本题有一定难度，考查虚拟语气和时态一致的用法，干扰项有一定的干扰。根据上下文逻辑，文章此处是说“爱因斯坦的计算帮助Bose理论成立，即原子会象原来他设想的那样运行”，此处只是表示理论成立，而不等于是经过验证的科学事实，所以要用假设的语气，此外整个句子都是用的过去时态，因此答案是A。

5、The most crucial problem any economic system faces is how to use its scarce resources. 【单选题】

A.puzzling

B.difficult

C.terrifying

D.urgent

正确答案:D

答案解析:crucial：至关紧要的，和urgent（紧急的）含义最接近；puzzling:（使）迷惑的、（使）为难的；difficult:困难的；terrifying:使感到恐怖的。
