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 (南極洲) 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 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 ______ 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.【單選題】
A.any
B.each
C.some
D.every
正確答案:D
答案解析:本題有一定難度,考查不定代詞every的用法,干擾項(xiàng)有一定的干擾。根據(jù)上下文邏輯,文章此處是說“……每六百萬年僅差一秒”,each后面不能跟復(fù)數(shù)名詞,因此最佳答案是D。
2、One Good Reason to Let Smallpox LiveIt\'s now a fair bet that we will never see the total extinction (滅絕) of the smallpox (天花) virus. When smallpox was completely got rid of in the world, scientists wanted to destroy the killer virus in the last two labs, one in the US and one in Russia. They asked: If smallpox has truly gone from the planet, what point was there in keeping these reserves?In reality, of course, it was naive to imagine that everyone would let go of such a powerful potential weapon. Undoubtedly several nations still have _____ vials (小藥瓶). and the last "official" stocks of live Virus bred mistrust of the US and Russia, forno obvious gain.Now American researchers have found an animal model of the human disease, opening the way fortests on new treatments and vaccines(疫苗). So once again there\'s a good reason to the virus, just in keep the disease puts in a reappearance.How do we case with the mistrust of the US and Russia? deal. Keep the virus Simple international support in a well - guarded UN laboratory that\'s open to all countries. The US will object, of course, just as it with a multilateral (多邊的) approach to just about everything. But it doesn\'t mean the idea is rejects. If the virus is useful, then let\'s wrong it the servant of all humanity make not just a part of it.【單選題】
A.more
B.few
C.a few
D.a lot
正確答案:C
答案解析:本題有一定難度,本題可用排除法,文章里沒有出現(xiàn)比較的含義,所以more可以排除掉,a lot后面不能接名詞,不能說a lot vials,所以也可以排除掉,依據(jù)上下文邏輯,文章此處是說“毫無疑問,幾個(gè)國家仍有幾瓶(病毒)”,此處要用“幾個(gè)”的意思,只能用a few,答案是C。
3、Breastfeeding Can Cut Cardiovascular RiskBreastfeeding can reduce the risk of a heart attack orstroke later in life and could prevent hundreds of thousands of deaths each year, researchers said on Friday. Babies who are breastfed have fewer childhood infections and allergies and are less ______ to obesity. British scientists have now shown that breastfeeding and slow growth in the first weeks and months of life has a protective effect against cardiovascular disease. "Diets that promote more rapid growth put babies at risk many years later in terms of raising their blood pressure, raising their cholesterol and increasing their tendency to diabetes and obesity-the four main risk factors forstroke and heart attack." said ProfessorAlan Lucas of the Institute of Child Health in London. "Our evidence suggests that the reason why breast-fed babies do better is because they grow more slowly in the early weeks."Lucas said the effects of breastfeeding on blood pressure and cholesterol later in life are greater than anything adults can do to control the risk factors forcardiovascular disease, other than taking drugs. An estimated 17 million people die of cardiovascular disease, particularly heart attack and strokes, each year, according to the World Health Organization. Lucas and his colleagues compared the health of 216 teenagers who as babies had either been breastfed orgiven different nutritional baby formulas\' They reported their findings in The Lancet medical journal. The teenagers who had been breastfed had a 14 percent lower ratio of bad to good cholesterol and lower concentrations of a protein that is a marker forcardiovascular disease risk. The researchers also found that regardless of the child\'s weight at birth, the faster the infants grew in the early weeks and months of life, the greater was their later risk of heart disease and stroke. The effect was the same forboth boys and girls. "The more human milk you have in the newborn period, the lower your cholesterol level is, the lower your blood pressure is 16 years later, "Lucas said. 【單選題】

6、The Value of AdvertisementMoney spent on advertising is worth spending. It serves directly to bring about a rapid sale of goods at reasonable prices, so setting up a firm home market and making it possible to provide forexport at good price. By drawing attention to new ideas it helps greatly to raise standards of living. By helping to increase demand it causes an increased need forlabor, and is therefore a nice way to fight unemployment. It lowers the costs of many services: without advertisements your daily newspaper would cost four times as much, the price of your television program would need to be doubled, and travel by bus orsubway would cost more. and perhaps most important of all, advertising provides a promise of reasonable value in the products and services you buy. Besides the fact that twenty-seven Acts of Parliament govern the terms of advertising, no regular advertiser dare produce anything that fails to live up to the promise of his advertisements. He might fool some people fora little while through misleading advertising. He will not do so forlong, forthe public has the good sense not to buy the poorgoods more than once. If you see a product frequently advertised, it is the proof I know that the product does what is promised forit, and that it has good value. Advertising does more forthe good of the public than any other force I can think of. There is one more point I feel I ought to touch on. Recently I heard a well-known television person declare that he was against advertising because it persuades rather than informs. He was telling us the real difference. Of course advertising tries to persuade. If its messages were nothing but information, that would be difficult to get more people to buy, foreven the choice of the colorof a shirt is a bit persuasive-advertising would be so boring that no one would pay any attention. But perhaps that is what the well-known television person wants.From the first paragraph we can see the writer believes that____.【單選題】
A.advertisements are worth reading
B.money spent on advertising is worthless
C.it is worthwhile spending money on a lot of things
D.to spend money on advertising is worthwhile
正確答案:D
答案解析:第1句是主題句,花在廣告上的錢是值得花的。接下的句子對是這一句的進(jìn)一步闡述。因此答案是D。
7、Seeing Red Means Danger AheadThe colorred often means danger and by paying attention, accidents can be prevented. In the future, the colorred also may help prevent danger at construction sites. Thanks to new work by engineers, bridge supports orother kinds of materials could one day contain a colorswitching material. It will turn red before a structure collapses orfalls apart. The secret ______ the colorswitching material is a particular type of molecule. A molecule is agroupof atoms held together by chemical bonds. Molecules come at all shapes and sizes, and make up everything. You can see, touch orfeel. 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 colorswitching molecule called a mechanophore (機(jī)械響應(yīng)性聚合物) which is about to break, it produce a color. When a polymer with mechanophore molecules becomes "injured" orweak, 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 colorswitching polymers in their lab. The test results proved encouraging. There is a way to get rid of the colorlight when a bright light is shone on the mechanophore. The broken bond is fixed and the red colordisappears. This "self-healing" may be a problem forengineers. They need to use the colorchanger in big construction projects that will be outside in sunlight. and sunlight will make the mechanophore\'s warming system useless. Sottos and her fellow scientists still have a lot of work to do before the colorswitching molecules can be used outside the lab. 【單選題】
A.on
B.behind
C.under
D.down
正確答案:B
答案解析:習(xí)慣用法,secret behind指什么東西背后的秘密;under也有底下的意思,但更多是強(qiáng)調(diào)地理空間上的;用于抽象事物,多用behind。

9、A Bad IdeaThink you can walk, drive, take phone calls, e - mail and listen to music at the same time 7 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 (小巧機(jī)械) when crossing the street.Who\'s to blame? _____. "We are under the impression that our brain can do more than it often can," says Rene Marois, a neuroscientist (神經(jīng)科學(xué)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. Agroupof 18 to 21 years old and agroupof 35 to 39 years old were given 90 seconds to translate images into numbers, using a simple code. The youngergroupdid 10 percent better when not interrupted. But when both groups were interrupted by a phone call oran instant message, the oldergroupmatched the youngergroupin 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 estimate is based on surveys with office workers. The surveys conclude that 28 percent of the workers\' time was spent on interruptions and recovery time before they returned to their main tasks.【單選題】
A.Talking on a cell phone while driving brings you joy anyway.
B.The estimate is based on surveys with office workers.
C.The youngergroupdid 10 percent better when not interrupted.
