1、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 or shade. Obviously, -120℃ is colder than our body can safely endure. Thank NASA science for well, 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 _____ down a gas to a temperature barely above absolute zero. They won a Nobel Prize in Physics in 2001 for their 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 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.burnt

B.blown

C.cut

D.cooled

正确答案:D

答案解析:本题有一定难度，考查词义辨析，但干扰项干扰不大。可以先看选项得到信息提示。根据上下文逻辑，文章此处是说“……成功将一种气体制冷，使其温度达到……”，答案是D。

2、It is absurd to predict that the sun will not rise tomorrow.【单选题】

A.ridiculous

B.funny

C.odd

D.foolish

正确答案:A

答案解析:题干大意：预测明天太阳不会升起是荒谬的。画线词absurd：荒谬的，和ridiculous完全是相同的意思。odd：奇怪的。funny：滑稽可笑的。foolish：愚蠢的。故答案选A。

3、What are my chances of promotion if I stay here?【单选题】

A.retirement

B.advertisement

C.advancement

D.replacement

正确答案:C

答案解析:如果我还待在这干，我有升职的机会吗？promotion指“提升，晋级”，和advancement的引申意义“晋升”是同义词，A项指“退休”，B项指“广告”，D项指“代替”，三项的干扰性不强。本题考查的是advancement的引申意义，有一定难度。

4、I was shocked when I saw the size of the telephone bill.【单选题】

A.excited

B.angry

C.lost

D.surprised

正确答案:D

答案解析:当看到电话账单的长度时我很震惊。本题难度不大，shocked指“震惊的”，和surprised“吃惊的”是近义词，B项“生气的”有一定的干扰性，其他干扰不大，最佳答案是D。

5、The Hurricane1. A hurricane (飓风) is a tropical storm with winds that have reached a constant speed of 74 miles per hour. Hurricane winds blow in a large spiral(螺旋) around a relative calm center known as the "eye". The "eye" is generally 20 to 30 miles wide, and the storm may extend outward 400 miles. As a hurricane nears land, it can bring heavy rains, high winds and storm surges(风暴潮). The storm surges and heavy rains can lead to flooding.2. Hurricanes are given a different label, depending on where they occur. If they begin over the North Atlantic Ocean, the Caribbean Sea, The Gulf of Mexico, or the Northeast Pacific Ocean, they are called hurricanes. Similar storms that occur in the Northwest Pacific Ocean west of the Internaional Date Line are called typhoons near Australia and in the Indian Ocean, they are referred to as tropical cyclones(龙卷风).3. When a hurricane hits land, it can do great damage through its fierce winds, heavy rains, inland(内陆的) flooding and huge waves crashing on to the shore. During a hurricane, homes, businesses and public buildings may be damaged or destroyed, roads and bridges can be washed away. A powerful hurricane can kill more people and destroy more property than any other natural disaster. Fishermen are at special risk from hurricanes as they may be at sea when a hurricane arrives and not be able to get to a safe harbor if they do not receive adequate warning.4. If a hurricane is comming in your area, the most important thing is to stay calm and find shelter immediately. Go to your safe room. If you do not have one, stay indoors during the hurricane and go to a safer place near the center of your home. Cover yourself with a blanket and be sure to keep away from windows and glass doors, because if the glass breaks it’s really dangerous. Do not be fooled if there is lull(暂停), it could be the eye of the storm—winds will pick up again.During a hurricane one should stay away from ______.【单选题】

A.different labels

B.window and glass doors

C.inland flooding

D.early warning

E.natural disaster

F.a constant speed

正确答案:B

答案解析:本题难度不大，答案依据比较明显，在文章最后一段的第三句：Cover yourself with blanket and be sure to keep away from windows and glass doors，…回来看选项，B项符合原文句意，是答案。

6、Seeing Red Means Danger AheadThe color red often means danger and by paying attention, accidents can be prevented. In the future, the color red 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 or falls apart.The secret behind the color - changing material is a particular type of molecule (分子). A molecule is a group of atoms (原子) held together by chemical bonds. Molecules come in all shapes and sizes and make up everything you can see, touch or feel. 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" or weak, 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 color light. When a bright light is shone on the mechanophore, the broken bond is fixed and the red color disappears. Thus "self - healing" may be a problem for engineers. 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。

7、AirbusDespite bulging order books, the mood at Airbus and Boeing is far from celebratory. Both aviation giants are moaning loudly that their production systems and supply chains are flawed, albeit for ostensibly different reasons. This week Louis Gallois, the boss of EADS, the Franco-German aerospace consortium that owns Airbus, added substance to warnings a week earlier by the planemaker’s chief executive, Tom Enders, that the dollar\'s decline was "life-threatening" for the firm. Mr. Gallois said it was no longer just a possibility that Airbus would have to move a large part of its production to "the dollar zone" or low-cost countries, but a certainty.Airbus is already in the middle of Power 8, a big restructuring plan that involves the loss of 10,000 jobs and the sale of several plants, which is meant to offset the losses caused by the delays in delivering the A380 superjumbo. But Power 8 assumed that a euro was worth $ 1.35, not today\'s $ 1.47. Mr. Gallois estimates that each 10-cent rise in the euro costs Airbus 1 billion. At present, Airbus makes 76% of its purchases within Europe, but generates over 60% of its sales elsewhere. It must now shift some production abroad.Airbus is now likely to forge ahead much further. Mr. Gallois suggests that when the A350 enters service in 2013, 70% of it will have been "purchased" in dollars, against 50% for the A380 and an average 24% of Airbus production today. Because Airbus insists that some of its European suppliers price in dollars that means about 50% of the A350\'s production will be outsourced. New aircraft, such as the A320\'s successor, may be made almost entirely outside the euro-zone.Airbus maintains that exchange rates are not the only reason for outsourcing: it is keen to tap into composite-manufacturing expertise wherever it exists. It also insists that it will not repeat the mistakes Boeing has made with its new 787 Dreamliner, about 80% of which has been outsourced. A few weeks ago Mike Bair, the executive responsible for the 787 programme, who was recently moved sideways after mounting production delays, launched a withering attack on some of the companies recruited to build the plane. He said that in future Boeing would not entrust design work to partners who "proved incapable of doing it", and would make suppliers build factories close to Boeing\'s main assembly operation, rather than flying semi-finished sections of the aircraft round the world on huge Dreamlifter transporters.It is too early to conclude that the two rivals are heading in opposite directions- Boeing renouncing the global supply chain just as Airbus adopts it. Each company has its own axe to grind. Airbus needs greater flexibility, and the weak dollar provides helpful cover as it takes on its grumbling unions. Boeing, for its part, wants to shift the blame for delays to the 787 on to its partners. The logic of global outsourcing in the aerospace industry remains powerful. Whatever they may be saying now. Airbus and Boeing are more likely to converge than to diverge.The word "converge" (line 7, paragraph 5) most probably means ______.【单选题】

A.unite

B.combine

C.meet

D.cooperate

正确答案:C

答案解析:猜词题。本段指出，虽然两个公司的说法不同，但对于海外采购的态度还是肯定的，因此它们今后更可能是向同一个方向会合而不是各自走上不同的道路。由此可见该词表示的是“会合”，故正确答案为C。

8、The use of the chemical may present a certain hazard to the laboratory workers. 【单选题】

A.protection

B.indication

C.immunity

D.danger

正确答案:D

答案解析:hazard和danger意思相同，危险、危害；protection：保护、防护；indication:指示、迹象；immunity:免疫力。

9、How to Interview PeopleInterviewing (采访) is one of those skills that you can only get better at. You will never again feel so ill at ease when you try it for the first time, and probably you\'ll never feel entirely comfortable trying to get from another person answers that he or she may be too shy to reveal. But at least half of the skill is mechanical. The rest is instinct, which can all be learned with experience.The basic tools for an interview are paper and two or three well-sharpened pencils. But keep your notebook or paper out of sight until you need it. There\'s nothing less likely to relax a person than the arrival of someone with a note-taking pad. ______ Take a while just to chat, judging what sort of person you\'re dealing with, getting him or her to trust you.Never go into an interview without doing whatever homework you can. If you are interviewing a town official, know his voting record. If it\'s an actor, know what plays he has been in. You will not be liked if you inquire about facts that you could have learned in advance.Many beginning interviewers are afraid that they are forcing the other person to answer questions and have no right to inquire about his personal secrets. This fear is almost 103 percent unnecessary. Unless the person really hates being interviewed, he is delighted that somebody wants to interview him. Most men and women lead lives that are uninteresting, and they grasp any chance to talk to an outsider who seems eager to listen.This doesn\'t necessarily mean that it will go well. In general you will be talking to people who have never been interviewed before, and they will get used to the process awkwardly, perhaps not giving you anything that you can use. Come back another day; it will go better. You will both even begin to enjoy it-proof that you aren\'t forcing your victim to do something he doesn\'t really want to.【单选题】

A.Come back another day; it will go better.

B.But at least half of the skill is mechanical.

C.As one philosopher interviewed in the film notes, they lack irony.

D.You will not be liked if you inquire about facts that you could have learned in advance.

E.This fear is almost 101 percent unnecessary.

F.Both of you need time to get to know each other.

正确答案:F

答案解析:前面提到不要使用a note-taking pad，后面Take a while just to chat，很显然作者强调的是不要开门见山地拿出小本开始记录，要花时间chat以增进相互之间的了解。所以选F。
