2、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。

3、I don\'t quite follow what she is saying. 【单选题】

A.believe

B.understand

C.explain

D.accept

正确答案:B

答案解析:follow此处有“理解”的意思，相当于understand; believe：相信；explain:解释；accept:接受。

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、Walking to Exercise the BrainDo you think sitting ａｎｄ　studying all the time will improve students grades? Think again. Getting some exercise may help, too.New research with older people suggests that taking regular walks helps them pay attention better than if they didn\'t exercise.Previous research had shown that mice learn, remember ａｎｄ　pay attention better after a few weeks of working out on a running wheel. Mice that exercise have greater blood flow to the brain than those who don\'t. Their brain cells also make more connections.Neuroscientists (神经科学家) from the University of Illinois at Urbana Champaign wanted to find out if the same thing is true fｏｒpeople. First, they measured the physical fitness of 41 adults, ages 58 to 77, after each person walked I mile. Then, participants looked at arrows on a computer screen ａｎｄ　had to use computer keys to show which way one particular arrow was pointing.Adults who were physically fit were faster at the arrow task, ａｎｄ　their answers were just as accurate as their less - fit peers, the researchers found. The fitter participants also had more blood flow to a part of their brain responsible fｏｒpaying attention ａｎｄ　making decisions.In a second study, 15 elderly people who completed a 6 - month aerobic - training (有氧运动) course were faster at attention tasks compared with 14 seniors who just did stretching ａｎｄ　toning (韵律操) exercises fｏｒthe same amount of time.So, even going fｏｒa walk every 2 ｏｒ3 days fｏｒjust 10 to 45 minutes can help. That should be good news fｏｒthe elderly.The effects of exercising on the brains of younger people haven\'t been studied yet. Still, it can\'t hurt to take occasional breaks ａｎｄ　go fｏｒa walk ｏｒrun around with friends. Whatever you do, though, don\'t try to read ａｎｄ　walk at the same time. You could end up hurting yourself!It is suggested in the last paragraph that people should ______.【单选题】

A.run around once a week

B.not read ａｎｄ　walk at the same time

C.go fｏｒa walk every day

D.not hurt their friends while exercising

正确答案:B

答案解析:本题难度不大，找到答案依据不难。答案依据在最后一段点评：本题难度不大，找到答案依据不难。第三句。这句话谈到。不论你做什么，都不要一边走路一边看书，回来看选项，很明显，B是同义解释，是答案。
