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 (南极洲) 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 _____ 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 every 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.【单选题】

A.whether

B.where

C.what

D.when

正确答案:A

答案解析:本题难度不大，考查whether or的用法，答案干扰项干扰不大。可以先看选项得到信息提示。很明显，此处是whether or结构，是说“温度（的多少）取决于你是否在阳光下或阴影里”，答案是A。

2、The Hurricane1. A hurricane (飓风) is a tropical storm with winds that have reached a constant speed of 74 miles per hour. Hurricane winds blow in a large spiral(螺旋) around a relative calm center known as the "eye". The "eye" is generally 20 to 30 miles wide, ａｎｄ　the storm may extend outward 400 miles. As a hurricane nears land, it can bring heavy rains, high winds ａｎｄ　storm surges(风暴潮). The storm surges ａｎｄ　heavy rains can lead to flooding.2. Hurricanes are given a different label, depending on where they occur. If they begin over the North Atlantic Ocean, the Caribbean Sea, The Gulf of Mexico, ｏｒthe Northeast Pacific Ocean, they are called hurricanes. Similar storms that occur in the Northwest Pacific Ocean west of the Internaional Date Line are called typhoons near Australia ａｎｄ　in the Indian Ocean, they are referred to as tropical cyclones(龙卷风).3. When a hurricane hits land, it can do great damage through its fierce winds, heavy rains, inland(内陆的) flooding ａｎｄ　huge waves crashing on to the shore. During a hurricane, homes, businesses ａｎｄ　public buildings may be damaged ｏｒdestroyed, roads ａｎｄ　bridges can be washed away. A powerful hurricane can kill more people ａｎｄ　destroy more property than any other natural disaster. Fishermen are at special risk from hurricanes as they may be at sea when a hurricane arrives ａｎｄ　not be able to get to a safe harbｏｒif they do not receive adequate warning.4. If a hurricane is comming in your area, the most important thing is to stay calm ａｎｄ　find shelter immediately. Go to your safe room. If you do not have one, stay indoors during the hurricane ａｎｄ　go to a safer place near the center of your home. Cover yourself with a blanket ａｎｄ　be sure to keep away from windows ａｎｄ　glass doors, because if the glass breaks it’s really dangerous. Do not be fooled if there is lull(暂停), it could be the eye of the storm—winds will pick up again.A powerful hurricane may become the most destructive ______.【单选题】

A.different labels

B.window ａｎｄ　glass doors

C.inlａｎｄ　flooding

D.early warning

E.natural disaster

F.a constant speed

正确答案:E

答案解析:本题有一定难度，需要认真寻找答案依据，答案依据在文章第三段的倒数第二句：A powerful hurricane can kill more people ａｎｄ　destroy more property than any other natural disaster。回来看选项，E项符合原文句意，是答案。

3、The carCars are an important part of life in the United States. Without a car most people feel that they are poor. ａｎｄ　even if a person is poｏｒhe doesn\'t feel really poｏｒwhen he has a car. Henry Ford was the man who first started making cars in large numbers. He probably didn\'t know how much the car was going to affect American culture. The car made the United Stated a nation on wheels. ａｎｄ　it helped make the United States what it is today. There are three main reasons why the car becomes so popular in the United States. First of all, the country is a huge one ａｎｄ　Americans like to move around in it. The car provides the most comfortable ａｎｄ　cheapest form of transportation. With a car people can go anylace without spending a lot of money. The second reason cars are popular is the fact that the United States never really developed an efficient ａｎｄ　inexpensive form of public transportation. Long-distance trains have never been as common in the country as they are in other parts of the world. Nowadays there is a good system of air-service provided by planes. But it is too expensive to be used frequently. The third reason is the most important one, though. The American spirit of independence is what really made cars popular. Americans don\'t like to wait fｏｒa bus, ｏｒa train ｏｒeven a plane. They don\'t like to have to follow an exact schedule. A car gives them the freedom to schedule their own time. ａｎｄ　this is the freedom that Americans want most to have. The gas shortage has caused a big problem fｏｒAmericans. But the answer will not be a bigger system of public transportation. The real solution will have to be a new kind of car, one that does not use so much gas. The real solution to the gas shortage problem is【单选题】

A.to make less cars

B.to develop a public transportation system

C.to make gas-saving cars

D.to develop train service

正确答案:C

答案解析:文章最后一句“The real solution will have to be a new kind ofcar, one that does not use so much gas”，不使用很多汽油的车，当然就是gas-saving cars（节能汽车）了。

4、Light Night, Dark StarsThousands of people around the globe step outside to gaze at their night sky. On a clear night, with no clouds, moonlight, ｏｒartificial lights to block the view, people can see more than 14,000 stars in the sky, says Dennis Ward, an astronomer(天文学家) with the University Corporation fｏｒAtmospheric Research( UCAR) in Boulder, Colo. But when people are surrounded by city lights, he says, they\'re lucky to see 150 stars.If you\'ve ever driven toward a big city at night ａｎｄ　seen its glow from a great distance, you\'ve witnessed light pollution. It occurs when light from streetlights, office buildings, signs, ａｎｄ　other sources streams into space ａｎｄ　illuminates (照亮) the night sky. This haze (朦胧) of light makes many stars invisible to people on Earth. Even at night, big cities like New York glow from light pollution, making stargazing difficult.Dust ａｎｄ　particles of pollution factories ａｎｄ　industries worsen the effects of light pollution. "If one city has a lot more light pollution than another," Ward says, "that city will suffer the effects of light pollution on a much greater scale."Hazy skies also make it far more difficult fｏｒastronomers to do their jobs.Cities are getting larger. Suburbs are growing in once dark, rural areas. Light from all this new development is increasingly obscuring (使变模糊) the faint (微弱的) light give off by distant stars. ａｎｄ　if scientists can\'t locate these objects, they can\'t learn more about them.Light pollution doesn\'t only affect star visibility. It can harm wild life too. It\'s clear that artificial light can attract animals, making them go off course. There\'s increasing evidence, fｏｒexample, that migrating (迁徙) birds use sunsets ａｎｄ　sunrises to help find their way, says Sydney Gauthreaux Jr. , a scientist at Clemson University in South Carolina, "When light occurs at night," he says, "it has a very disruptive (破坏性的) influence." Sometimes birds fly into lighted towers, high - rises, ａｎｄ　cables from radio ａｎｄ　television towers. Experts estimate that millions of birds die this way every year.On a clear night, people can see ______.【单选题】

A.150 stars

B.hundreds of stars

C.one thousａｎｄ　stars

D.more than 14,000 stars

正确答案:D

答案解析:本题难度不大，答案依据比较明显，在文章第一段第二句，这句话主要谈到，在晴朗的夜晚人们能看到14，000多颗星星，回来看选项，D项符合原文句意，是答案。

5、We\'ve been through some rough times together.【单选题】

A.long

B.happy

C.difficult

D.short

正确答案:C

答案解析:我们一起经历了艰难时刻。本题考查的是引申意义，有一定难度。rough 一般意义指“粗糙的”，引申意义指“艰难的”，和difficult“困难的”是近义词，其他三项都是常用词，和答案意义差异较大，干扰性不强。答案是C。
