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 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 _____ 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】

D.so

正确答案:D

答案解析:本段的第2句的前半句与后半句是因果关系，连词要选so。

2、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.Why did Dr. Shelelle think the correlation between vitamin A ａｎｄ　lung cancer protection was logical?【单选题】

A.Vitamin A causes lung cancer.

B.Vitamin A cures lung cancer.

C.Vitamin A is necessary fｏｒthe growth of the tissue lining the lungs.

D.Vitamin A is a molecule that prevents smoke from being inhaled.

正确答案:C

答案解析:根据第2段最后一句，“这种关系符合逻辑，因为维生素A对于排列在肺部呼吸通道的上皮组织结构的生长是必不可少的”。

3、The dancers moved across the dimly lit stage.【单选题】

4、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 fｏｒit. 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. The company says it is the only test in the UK to be approved by the government.Genera was formed five years ago ａｎｄ　until October last year had only five employees; it now employs 14. Mr. Headlａｎｄ　believes that the company should make around $19 million by the end of the year in the UK alone.Before he ｓｅｔup Genera. Dr Parton had worked fｏｒa British water company.【单选题】
