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 _____ 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-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 fｏｒtheir 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.Earth

B.space

C.planet

D.star

正确答案:B

答案解析:纵观本段，内容是叙述宇宙空间的温度。选项B的space是“宇宙空间”的意思，所以是答案。其他三个选项Earth（地球）、planet（行星）、star（恒星）在词义上都不合适。

2、DyslexiaAs many as 20% of all children in the United States suffer from some form of the learning disｏｒｃｅｒcalled dyslexia.Experts on dyslexia say that the problem is not disease. They say that persons with dyslexia use information in a different way. One of the world\'s great thinkers ａｎｄ　scientists, Albert Einstein was dyslexic. Einstein said that he never thought in words the way that most people do. He said that he thought in pictures instead. The American inventｏｒThomas Edison was also dyslexic. Dyslexia first was recognized in Europe ａｎｄ　the United States more than 80 year ago. Many years passed before doctors discovered that persons with the disｏｒｃｅｒwere not mentally slow ｏｒdisabled. The doctors found that the brains of persons with dyslexia are different. In most people, the left side of the brain, the part that controls language is larger than the right side. In persons with dyslexia, the right’ side of the brain is bigger. Doctors are not sure what causes this difference. However, research has shown that dyslexia is more common in males that in females, ａｎｄ　it is found more often in persons who are left-handed. No one knows the cause of dyslexia, but some scientists believe that it may result from chemical changes in a baby\'s body long before it is born. They are trying to find ways to teach persons with dyslexia. Dyslexic persons think differently ａｎｄ　need special kinds of teaching help. After they have solved their problems with language, they often show themselves to be especially intelligent ｏｒcreative.It is believed that dyslexia is related to the bad habits of a baby\'s mother.【单选题】

A.Right

B.Wrong

C.Not mentioned

正确答案:C

答案解析:题目中的关键词应为bad habits和baby\'s mother，但是通读全文，我们只找到了无关信息baby\'s body，由此可见，该题正确答案为C。

3、Geology ａｎｄ　Heap(1)The importance of particular metals in the human diet has been realized within the past few decades, ａｎｄ　the idea that geology might be related to health has been recognized fｏｒa number of elements such as iodine, zinc ａｎｄ　selenium. Fｏｒexample, soils with low iodine contents produce crops, ａｎｄ　animals deficient in iodine. A lack of iodine in the human diet leads to some serious diseases.(2)The ultimate source of metals within the human body is rocks, which weather into soil, gaining ｏｒlosing some of their chemical constituents. The crops we eat selectively remove from the soil the elements that they require fｏｒgrowth. The water we drink contains trace elements leached from rock ａｎｄ　soil. Thus the geology ａｎｄ　geochemistry of the environment have effects on the chemistry ａｎｄ　health of plants, animals ａｎｄ　people.(3)So far there is no data to suggest that people living on metal-rich soils experience a potential health hazard. The levels of metals within naturally contaminated soils are generally not high enough to cause serious health problems. Living on metal-rich soils does not represent a health risk unless large quantities of soil are digested ｏｒmetal-rich dust is inhaled. However, small children are particularly exposed to metal-rich topsoil in playgrounds ａｎｄ　gardens. They are also the most likely ones to eat potentially dangerous metal-rich soil.(4)Heavy metals are persistent: they do not break down to other chemicals in the environment. Industrially polluted sites usually undergo intensive clean-up ａｎｄ　rehabilitation because heavy metals are a health concern once they enter the food chain. Some trace metals are alleged to cause cancer ａｎｄ　are also known to cause poisoning(5)In contrast, naturally contaminated soils have not been subject too risk assessment studies ａｎｄ　rehabilitation measures, despite the fact that they frequently possess metal concentrations well above those of such polluted by humans ａｎｄ　above environmental quality criteria.(6)There is a vital need to understａｎｄ　the potential risks ａｎｄ　long-term health effects of living on naturally contaminated soils. Future environmental investigations of naturally polluted soils should concentrate on the potential pathways of metals into the food chain ａｎｄ　human body. Geologists should be part of such studies as they can provide the essential background information on rock ａｎｄ　soil chemistry as well as the chemical forms of heavy metal pollution.Paragraph l______【单选题】

A.No Evidence to Indicate Bad of Naturally Contaminated Soil

B.Potential Hazards of Human Contaminated Soils

C.Research an Channels of Heavy Metals Getting into Human Food Chain

D.Geology ａｎｄ　Health Problems

E.Rocks----the Ultimate Source of Soil Pollution

F.Long-term Health Effects on Children

正确答案:D

答案解析:第1段点出主题，即某些金属进入人体可能与地质有关。

4、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. ____ 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. 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.【单选题】

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.

D.However, an Oxford University research suggests this perception is open to question.

E.Scientists say that our multitasking (多任务处理) abilities are limited.

F.ａｎｄ　you\'ll be fined $ 100 if you do so on a New York city street.

正确答案:F

答案解析:本题难度不是很大。可用排除法和代入法。本题的上文谈到纽约新的法律规定在走路开车时不能打电话、发邮件、听音乐，下文谈到新法律发生效力的时间，所以可以推断此处会继续跟着上文展开阐述，应该讲如果你做了会导致什么结果，回来看选项，把F代入文中，符合逻辑，答案是F。

5、A Carrot a Day Keeps Cancer AwayAmong all the malignancies, lung cancer is the biggest killer: more than 100,000 Americans a year die of the disease. Giving up smoking is one of obvious way to reduce the risk, but another answer may lie in the kitchen. According to a new report, even heavy smokers may be protected from developing lung cancer by a simple dietary measure: a daily portion of carrots, spinach ｏｒany other vegetable ｏｒfruit containing a form of vitamin A called carotene.The finding, published in the British medical journal The Lancet, is part of a long-range investigation of diet ａｎｄ　disease. Since 1957 a team of American researchers has monitored the dietary habits ａｎｄ　medical histories of 2,000 middle-aged men employed by the Western Electric Co. in Chicago. Led by Dr. Richard Shelelle of Chicago\'s Rush-Presbyterian, St. Luke\'s Medical Center, the researchers recently began to sort out the links between the subjects\' dietary patterns ａｎｄ　cancer. Other studies of animals ａｎｄ　humans have suggested that vitamin A offers some protection against lung cancer. The correlation seemed logical, since vitamin A is essential fｏｒthe growth of the epithelial (上皮的) tissue that lines the airways of the lungs.Vegetables: But the earlier research did not distinguish between two different forms of the vitamin. "Preformed" vitamin A, known as retinol, is found mainly in liver ａｎｄ　dairy products like milk, cheese, butter ａｎｄ　eggs. But vitamin A is also made in the body from carotene, which is abundant in a variety of vegetables ａｎｄ　fruits, including carrots, spinach, squash, tomatoes, sweet potatoes ａｎｄ　apples.In the Western Electric study, Shekelle ａｎｄ　his colleagues found little correlation between the incidence of lung cancer ａｎｄ　the consumption of foods containing preformed vitamin A, but when they examined the data on carotene intake, they discovered a significant relationship. Among the488 men who had the lowest level of carotene consumption, there were fourteen cases of lung cancer, in aｇｒｏｕｐof the same size that ate the most carotene, only two cases developed. The apparent protective effect of carotene held up even fｏｒlongtime smokers but to a lesser degree.Further studies will be necessary before the link between lung cancer ａｎｄ　carotene can be firmly established. In the meantime, researchers warn against taking large numbers of vitamin A pills, because the tablets contain a form of the chemical that can be extremely toxic in high doses. Instead, they advise a well-balance diet that includes foods rich in carotene. Fｏｒa smoker, a half-cup of carrots every day might possibly make the difference between life ａｎｄ　death.What does "malignancy" in the text refer to?【单选题】

A.Cancer.

B.Sickness.

C.Vitamins.

D.Disease.

正确答案:A

答案解析:这是一个很生僻的词，很少有考生认识，但是根据第1句话，“在众多的malignancy中，肺癌是最大的杀手”，这说明它是“癌症”。因此答案是A。
