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 suits 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 _____ 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】

C.must

D.can

正确答案:B

答案解析:本句的主句中的谓语动词用的是过去时helped，根据“主句为过去时态，宾语从句一般也要用过去时态”这一时态一致原则，本题要选would。

Together the two boys, who go to Escondido High School in California, have had the difficult job of learning in schools where the majority of the students can speak and hear.Orlando lost his hearing at the age of one. German was borned deaf, and his parents moved from Mexico to find a school where he could learn sign language. He met Orlando on their first day of kindergarten."We were in a special class with about 25 other deaf kids," German remembers. "Before then, I didn\'t know I was deaf and I was different.""Being young and deaf in regular classes was very hard," signs Orlando. "The other kids didn\'t understand us and we didn\'t understand them. But we\'ve all grown up together, and today, I\'m popular because I\'m deaf. Kids try hard to communicate with me."Some things are very difficult for the two boys. "We can\'t talk on the phone. so if we need help, we can\'t call an emergency service," German signs. "And we can\'t order food in a drive - thru."Despite their difficulties, the two boys have found work putting food in bags at a local supermarket. They got their jobs through a "workability" program designed for teenagers from local schools with different types of learning disabilities.German has worked in the supermarket since August, and Orlando started in November."The other people who work here have been very nice to us," Orlando signs. "They even sign sometimes. At first, we were nervous, but we\'ve learned a lot and we\'re getting better.The opportunity to earn money has been exciting, both boys said.

3、A Bad IdeaThink you can walk, drive, take phone calls, e - mail and listen to music at the same time? Well, New York\'s new law says you can\'t. And you\'ll be fined $ 100 if you do so on a New York city street. The law went into force last month, following research and a shocking number of accidents that involved. people using electronic gadgets (小巧机械) when crossing the street.Who\'s to blame? Scientists say that our multitasking (多任务处理) abilities are limited. "We are under the impression that our brain can do more than it often can," says Rene Marois, a neuroscientist (神经科学家) in Tennessee. "But a core limitation is the inability to concentrate on two things at once."The young people are often considered the great multitaskers. However, an Oxford University research suggests this perception is open to question. A group of 18 to 21 years old and a group of 35 to 39 years old were given 90 seconds to translate images into numbers, using a simple code. The younger group did 10 percent better when not interrupted. But when both groups were interrupted by a phone call or an instant message, the older group matched the younger group in speed and accuracy.It is difficult to measure the productivity lost by multitaskers. Jonathan Spira, chief analyst at Basex, a business - research firm, estimates that the cost of interruptions to the American economy is nearly $650 billion a year, ____ The surveys conclude that 28 percent of the workers\' time was spent on interruptions and recovery time before they returned to their main tasks. 【单选题】

4、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 l ____【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:E

答案解析:本段的第3句点出了“methane\'s heat-trapping power in the atmosphere is 21 times stronger than carbon dioxide. ”

5、Fighting for a Brighter Future for WomenWhen I was asked what it means to be a woman running for president, I always gave the same answer that I was proud to be running as a woman, but I was running because thought I\'d be the best president.But I am a woman and, like millions of women, I know there are still barriers and biases (偏见) out there, often unconscious, and I want to build an America that respects and embraces the potential of every last one of us.I ran as a daughter who benefited from opportunities my mother never dreamed of. I ran as a mother who worried about my daughter\'s future and a mother who wants to leave all children brighter tomorrows.To build that future I see, we must make sure that women and men understand the struggles of their grandmothers and their mothers, and that women enjoy equal opportunities, equal pay, and equal respect.Let us resolve and work toward achieving very simple propositions (命题): there are no acceptable limits, and there are no acceptable prejudices in the 21 st century in our country.You can also be so proud of it, from now on, it will be unremarkable for a woman to win primary state victories, unremarkable to let a woman in a close race to be our nominee (被提名者), unremarkable to think that a woman can be the president of the United States. And this is truly remarkable my friends.We are disappointed that we couldn\'t go all of the way, especially the young people who put so much into this campaign. It would break my heart if, in falling short of my goal, I in any way discouraged any of you from pursuing yours.We always aim high, work hard, and care deeply about what you believe in. And when you stumble (绰倒), keep faith. And, when you\'re knocked down, get right back up and never listen to anyone who says you can\'t or shouldn\'t go on.As we gather here today in this historic, magnificent building, the 50th woman will leave the Earth and orbit (绕轨道运行) overhead. If we can blast 50 women into space, we will someday launch a woman into the White House.Hillary Clinton believed that if she were elected president of the United States, she would be the best.【单选题】

9、New Product Will Save LivesDrinking water that looks clean may still contain bugs, which can cause illness. A small company called Genera Technologies has produced a testing method in three stages, which shows whether water is safe. The new test shows if water needs chemicals added to it, to destroy anything harmful. It was invented by scientist Dr. Adrian Patton, who started Genera five years ago. He and his employees have developed the test together with a British water company.Andy Headland, Genera\'s marketing director, recently presented the test at a conference in the USA and forecast good American sales for it. Genera has already sold 11 0fits tests at $42,500 a time in the UK and has a further four on order. It expects to sell another 25 tests before the end of March.

10、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. Both of you need time to get to know each other. 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. ______ 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 104 percent unnecessary.

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

正确答案:A

答案解析:前一句提到“not giving you anything”，后一句提到“You will both even begin to enjoy it"，由此可以判断出在被采访者由于以前不适应这种场合没能给你提供任何你想得到的信息时，不妨改天重新开始。所以选A。
