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 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-designed space _____ that protect astronauts from these temperature extremes.The space temperatures just discussed affect only our area 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 temperature barely above absolute zero. They won a Nobel Prize in Physics in 2001 for their work not a discovery in this car.Why is the two scientists\' work so important to science?In the 1920s, Satyendra Nath Bose was studying an interesting theory about particles we now call photons. Bose had trouble convincing Other scientists to believe so he contacted Albert Einstein. Einstein\'s calculations helped him theorize would behave as Bose thought but only at very cold temperatures.Scientists have also discovered that ultra-cold 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(d=vxt). With the long distances involved in space travel to know time as accurately as possible to get accurate distance.【单选题】

A.foods

B.beds

C.tools

D.suits

正确答案:D

答案解析:上文说-120℃是宇航员无法忍受的温度，下文说美国国家航空和航天管理局生产的某种装置以protect astronauts from these temperature extremes(保护宇航员不受极端温度的侵害)。很明显，这一装置就是space suits。

2、A Strong Greenhouse Gas1 Methane is a colorless, odorless gas; it is also a potent greenhouse gas, and once released into the atmospheres, it absorbs beat radiating from Earth\'s surface. That\'s why methane is a major contributor to the planet\'s increasing temperature rise or global warming. Molecule for molecule, methane\'s heat-trapping power in the atmosphere is 21 times stronger than carbon dioxide, the most abundant greenhouse gas.2 With 13 billion cows belching almost constantly around the world (100 million in the U. S. alone), it\'s no surprise that menace released by livestock is one of the chief sources of the gas. Other prime methane sources: petroleum, drilling, coal mining, solid-waste landfills and wetlands.3 Greenhouse gases like methane and carbon dioxide make up only a small part of Earth\'s atmosphere, which is 78 percent nitrogen and nearly 21 percent oxygen. And without greenhouse gases to trap the sun\'s heat and warm the planet, life as we know it couldn\'t exist. But in the last200 years, human activity that requires burning oil, natural gas, and coal for energy has magnified the greenhouse effect.4 Atmospheric concentrations of methane have more than doubled in the last two centuries. Blame for this often focuses on big industries and gas-guzzling vehicles. But agriculture plays a major role, too. In the past 40 years alone, the global cattle population has doubled.5 Cows munch mostly grasses and hay yet they grow big and hefty. Why? Because of the rumen. The rumen holds 160 liters of food and billions of microbes. These microscopic bacteria and protozoa break down cellulose and Fiber into digestible nutrients. A cow couldn\'t live without its microbes. As the microbes digest cellulose, trey release methane. The process occurs in all animals with a rumen (cows, sheep, and goats, for example), and it makes them very gassy. It\'s part of their normal digestion process. When they drew their cud, they regurgitate some food to rechew it, and all this gas comes out. The average cow expels 600 liters of methane a day.That\'s why we say livestock gas is also a major factor of causing the global warming.Paragraph 5 ____【单选题】

A.Life of Macroscopic Bacteria in Livestock\'s Rumen

B.Ways to Reduce Methane\'s Heat-trapping Power

C.Agriculture Also Contributes to Increased Concentrations of Methane in the Atmosphere

D.Why Livestock Releases Methane

E.Methane as a Strong Greenhouse Gas

F.Livestock as a Prime Factor of the Greenhouse Effect

正确答案:D

答案解析:本段从科学的角度分析反刍动物为什么会释放出甲烷。

3、Gun Rights in the USImmediately after the shooting at Virginia Tech University, Americans gathered to mourn (致哀) the dead. The president and the state governer both hurried there to share the grief. But the majority of Americans still cling to their right to own weapons.Strictly speaking, the US is not the only country here gun violence has destroyed lives, families and communities in everyday circumstance. But the US is one of the few countries that seem unwilling and politically incapable of doing anything serious to stop it.In countries like Britain and Canada, the government adopted strict ____ control soon after serious gun violence incidents. US leaders, however, are held hostage by the gun lobby (院外活动集团) and the electoral (选举) system.The powerful National Rifle Association, the major supporter of gun rights in the US, is too strong for any party to take on. Most Republicans oppose gun control anyway. Over the years, the Democrats have found that they can either campaign for gun control or win power, not both, they prefer power.According to the US Bureau of Justice Statistics, firearm (火器) incidents accounted for nine percent of the 4.7 million violent crimes in 2005. So although opinion polls show most Americans want stricter gun laws, many people don\'t want to give up their arms they keep to protect themselves.Dave Hancock, a Virginia gun lover, is one example. In an interview he said, "If one professor in the Virginia incident had been carrying a legal weapon, they might have been able to stop all this. "In his opinion, the massacre (大屠杀) is an argument for more people to carry weapons, not fewer.Americans\' clinging to the right to bear arms is not just a fear of crime, but a mistrust of government, commented UK\'s Guardian newspaper.One Virginia resident, who had a permit to carry a concealed (隐藏的) firearm, told the Guardian that it was every American\'s responsibility to have a gun."Each person," he said, "should not rely solely on the government for protection."【单选题】

6、Electric BackpackBackpacks are convenient. They can hold your books, your lunch, and a change of clothes, leaving your hands free to do other things. Someday, if you don\'t mind carrying a heavy load, your backpacks might also power your MP3 player, keep your cell phone running, and maybe even light your way home.Lawrence C. Rome and his colleagues from the University of Pennsylvania in Philadelphia and the Marine Biological Laboratory in Woods Hole, Mass, have invented a backpack that makes electricity from energy produced while its wearer walks. In military actions, search-and-rescue operations, and scientific field studies, people rely increasingly on cell phones, global positioning system (GPS) receivers, night-vision goggles, and other battery-powered devices to get around and do their work. The backpack\'s electricity-generating feature could dramatically reduce the amount of a wearer\'s load now devoted to spare batteries, report Rome and his colleagues in the Sept. 9, Science.The backpack\'s electricity-creating powers depend on springs used to hang a cloth pack from its metal frame. The frame sits against the wearer\'s back, and the whole pack moves up and down as the person walks. A gear mechanism converts vertical movements of the pack to rotary motions of an electrical generator, producing up to 7. 4 watts.Unexpectedly, tests showed that wearers of the new backpack alter their gaits in response to the pack\'s oscillations, so that they carry loads more comfortably and with less effort than they do ordinary backpacks. Because of that surprising advantage, Rome plans to commercialize both electric and non-electric versions of the backpack.The backpack could be especially useful for soldiers, scientists, mountaineers, and emergency workers who typically carry heavy backpacks. For the rest of us, power-generating backpacks could make it possible to walk, play video games, watch TV, and listen to music, all at the same time. Electricity-generating packs aren\'t on the market yet, but if you do get one eventually, just make sure to look both ways before crossing the street!According to Paragraph 4, what does Rome plan to do?【单选题】

A.To make the backpack more comfortable for the wearer.

B.To put the backpack on the market.

C.To test the advantage of the backpack.

D.To promote the backpack in a newspaper or on television.

正确答案:B

答案解析:第4段最后一句的意思是：Rome计划将这种背包商业化，即推向市场。A、C、D在文中均未提到。D的意思是为背包做广告。

7、Making Yourself a Good RecordIf you are an American and you think you might need to borrow money someday, the best thing to do is to start early.That\'s because just as many employers want to hire only people with experience, banks and other creditors are usually reluctant to lend to those without a proven track record of paying back, on time, the money they have borrowed.But if you need experience just to get a start, how do you get that start in the first place?With a little help from your parents usually, while you are still financially dependent on them. It is easy to get a credit card or student loan when you are in college, because banks figure your parents will bail you out if you fail to pay.So just as students take on internships to build up their resumes, one s university time can be a good time to work on another important personal record: the credit reportCredit reports are a ______ of one\'s personal credit history, gathered by a credit reporting agency, or CRA.Banks, and companies including hospitals, landlords and insurance companies-regularly report to the three main CRAs in the US on how their customers are doing at paying back the money they owe.Anyone with a "legitimate business need" has the right to order individuals\' reports from the CRAs. Potential creditors usually compile the information in the reports into a credit "score", ranking the level of creditworthiness. Lack of experience in borrowing in addition to a bad record of doing so, can result in a low score.Even if you are not considering taking out a loan for such a large purchase as a home or car, your credit report can be important to getting through life. Landlords often ask for the reports to judge whether a person can be trusted to pay the rent. Credit checks are necessary for getting a credit card, even for purchasing a mobile phone calling plan.People can obtain a copy of their own credit report, usually at a cost of around US$ 8-9. Some consumer organizations recommend doing this once a year to allow one to catch any mistakes that have slipped into the records or, even worse, to find out whether any fraud has taken place. Though the system is controlled by laws meant to protect people\'s privacy, it isn\'t fool-proof. Sometimes people take out bad loads in others\' names, ruining their records.In a society addicted tocredit, that can be a disaster.【单选题】

A.explanation

B.investigation

C.summary

D.examination

正确答案:C

答案解析:空格前有不定冠词“a”，因此选取的单词的首字母的发音不能是元音，故C项为正确答案。

8、CultureCulture is one of the most challenging elements of the international marketplace. This system of learned behavior patterns characteristic of the members of a shaped by a set of dynamic variables: language, religion, values and attitudes, manners and customs, aesthetics, technology, education, and social institutions. To cope with this system, an international manager needs both factual and interpretive knowledge of culture. To some extent, the factual knowledge can be learned; its interpretation comes only through experience.The most complicated problems in dealing with the cultural environment stem from the fact that one cannot learn culture one has to live it. Two schools of thought exist in the business world on how to deal with cultural diversity. One is that business is business the world around, following the model of Pepsi and McDonald\'s. In some cases, globalization is a fact of life; however, cultural differences are still far from converging.The other school proposes that companies must tailor business approaches to individual cultures. Setting up policies and procedures in each country has been compared to an organ transplant; the critical question centers around acceptance or rejection. The major challenge to the international manager is to make sure that rejection is not a result of cultural myopia or even blindness.Fortune examined the international performance of a dozen large companies that earn 20 percent or overseas. The internationally successful companies all share an important quality: patience. They have not rushed into situations but rather built their operations carefully by following the most basic business principles. These principles are to know your adversary, know your audience, and know your customer.This article is supposed. to be most useful for those _____.【单选题】

A.who are interested in researching the topic of cultural diversity

B.who have connections to more than one type of culture

C.who want to travel abroad

D.who want to run business on International Scale

正确答案:D

答案解析:由文中的例子可以知道，不是研究多种文化形态，而是文化背景对商业运作的影响，所以D是正确答案。

9、Operatunity1. Operatunity is a TV talent show for amateur opera singers, The winners get the chance to sing with the English National Opera. When two housewives, Denise Leigh and Jane Gilchrist won in 2002, their lives changed forever, As they sang Verdi\'s Rigoletto at the Coliseum (音乐厅) in Rome, they were transformed from working mothers into opera celebrities (名人).2. "I live in the village I was born in," says Denise, who is blind. "Lots of my neighbours are family, and my life is all about my three children. Jane, who worked as a cleaner and a shop assistant, was in a similar situation." She says. All I had to look forward to was seeing my four children grow up, and I love them, but ... you know there must be more things than life. Winning Operatunity has opened up avenues I never knew existed."3. "Last year was amazing," Denise continues, "Last month was Paris, before that we were recording at Abbey Road, in London, and recently we had our album launch at the Royal Opera House" "We\'ve been treated like princesses," laughs Jane, "... champagne, chocolates, five - star hotels ..."4.

They couldn’t take their children with them while they were away singing, so they had to organise childcare. However, there\'s been no problem with the physical side of singing: "We didn\'t have to worry about that as we\'ve had lots of help and wonderful voice training." says Jane. They also had to learn to deal with the media." The kids loved the fact that they could stay up and watch us on TV, but I just couldn\'t understand why some newspapers were more interested in the fact I divorced at 21, rather than the fact I had just sung at the Coliseum, says Denise.Before becoming famous, Denise and Jane worked in order to ____.【单选题】
