1、Rockets in the SkyIf someone asked you. "What coloris the sky?" I expect that you would answer, "Blue." I am afraid that you would be wrong. The sky has no color. When we see blue, we are looking at blue sunlight. The sunlight is shining on little bits of dust in the air. We know that there is air all around the world. We could not breathe without air. Airplanes could not fly without air. They need air to lift their wings. Airplanes cannot fly very high because as they go higher the air gets thinner. If we go far enough away from the earth, we find there is no air. What is the sky? The sky is space. In this space there is nothing except the sun, the moon and all the stars. Scientists have always wanted to know more about the other worlds in the space. They have looked at them through telescopes and in this way they have found out a great deal. The moon is about 384,000 kilometers away from the earth. An airplane cannot fly to the moon but there is a thing that can fly even when there is no air. This is rocket. I am sure that you are asking. "How does a rocket fly?" If you want to know, get a balloon and then blow it up until it is quite big. Do not tie up the neck of the balloon. Let go! The balloon will fly off through the air very quickly. The air inside the balloon tries to get out. It rushes out through neck of the ball off and this pushes the balloon through the air. It does not need wings like an air plane. This is how a rocket works. It is not made of rubber like a balloon, of course. It is made of metal. The metal must not be heavy but it must be very strong. There is gas inside the rocket which is made very hot. When it rushes out of the end of the rocket, the rocket is pushed up into the air. Rockets can fly far out into space. Rockets with men inside them have already reached the moon. Several rockets, without men inside them, have been sent to other worlds much farther away. One day rockets may be able to go anywhere in the space. A rocket is pushed up into the air when____. 【单选题】
A.hot gas rushes out of its head.
B.it is powered by gas.
C.hot gas rushes out of its bottom.
D.hot gas rushes out of its neck.
正确答案:C
答案解析:根据文章倒数第2段最后一句( When it rushes out of the end of the rocket)。

4、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 (机械响应性聚合物) 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. 【单选题】
A.on
B.behind
C.under
D.down
正确答案:B
答案解析:习惯用法,secret behind指什么东西背后的秘密;under也有底下的意思,但更多是强调地理空间上的;用于抽象事物,多用behind。
5、Houses of FutureWhat will houses be like in thirty years\' time? No one really knows, but architects are trying to predict what our home will be likeE. Future houses will have to be flexible. In thirty years\' time even more of us will be working at home. So we will have to be able to use areas of the house forwork forpart of the day and forliving forthe rest. Families grow and change with children arriving, growing up and leaving home. The house ofthe future will have to grow and change with the familyF, nothing will be as fixed as it is now. The house will always be changing to meet changing needs. Everyone agrees that in thirty years\' time we will be living in "intelligent" houses. We will be able to talk to our kitchen machines and discuss with them what to do. Like this, "we\'ll be having a party this weekend. What food shall we cook?" ______. We will be able to leave most of the cooking to the machines, just tasting things from time to time to check. The house of the future will be personal-each house, you will be able to change the colorofthe wall easily, you won\'t have to paint them, you\'ll be able to tell the wall to change the color! and if you don\'t like the colorthe next day, you will be able to have a new one. The only thing you won\'t be able to do is moving the house somewhere else.【单选题】
A.you will be able to change the colorofthe wall easily
B.The only thing you won\'t be able to do is moving the house somewhere else
C.and the machine will tell us what food we will have to buy and how to cook it

F.he kids might take their bedrooms with them as they have
正确答案:C
答案解析:意思是“智能机器会告诉我们需买的食材和烹饪的方法”,与文章中智能机器如何工作相符。
6、Singing Alarms Could Save the BlindIf you cannot see, you may not be able to find your way out of a burning building and that could be fatal. A company in Leeds could change all that with directional sound alarms capable of guiding you to the exit. Sound Alert, a company run by the University of Leeds, is installing the alarms in a residential home forblind people in Sommersetand a resource centre forthe blind in Columbia. The alarms produce a wide range of frequencies that enable the brain to determine where the sound is coming from. Deborah Withington of Sound Alert says that the alarms use most of the frequencies that can be heard by humans. "It\'s a burst of white noise that people say sounds like static on the radio," she says. "Its life-saving potential is great."She conducted an experiment in which people were filmed by thermal-imaging cameras trying to find their way out of a large smoke-filled room. It took them nearly four minutes to find the door______ a sound alarm, but only 15 seconds with one. Withington studies how the brain processes sounds at the university. She says that the source of a wide band of frequencies can be pinpointed more easily than the source of a narrow band. Alarms basedon the same concept have already been installed on emergency vehicles. The alarms will also include rising orfalling frequencies to indicate whether people should go up ordown stairs. They were developed with the aid of a large grant from British Nuclear Fuels. 【单选题】
A.on
B.near
C.without
D.from
正确答案:C
答案解析:逗号后面的one应该是指a sound alarm。从连词but可以推断,前后应是意思相反,后面已有了with,那么前句应是without。所以选择C。
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 behind 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 (机械响应性聚合物) which is about to break, it produce a color. When a polymer with mechanophore molecules becomes "injured" orweak, one of the mechanophore bonds ______ and the material turns red. "It\'s a really simple detection method.

A.closes
B.breaks
C.increases
D.bums
正确答案:B
答案解析:前文为bond,意为联系,后文说到变红,说明不是在常态之下,那么联系是常态,联系断开才与红相对应,所以选break。
8、The great change of the city astonished all the visitors.【单选题】

D.moved
正确答案:A
答案解析:这座城市发生的大变化使所有的参观者惊讶。本题难度不大,干扰项干扰不强。astonished和surprised都可指“吃惊的”,B项指“使惊吓”,最佳答案是A。
9、Looking to the FutureWhen a magazine forhigh-school students asked its readers what life would be like in twenty years, they said: Machines would be run by solar power. Buildings would rotate so they could follow the sun to take maximum advantage of its light and heat. Walls would "radiate light" and "change colorwith the push of a buttons." Food would be replaced by pills. School would be taught "by electrical impulse while we sleep." Cars would have radar. Does this sound like the year 2000? Actually, the article was written in 1958 and the question was, "what will life be like in 1978?". The future is much too important to simply guess about, the way the high school students did. So experts are regularly asked to predict accurately.By carefully studying the present, skilled businessmen, scientists, and politicians are supposedly able to figure out in advance what will happen. But can they? One expert on cities wrote: Cities of the future would not be crowded but would have space forfarms and fields. People would travel to world in "airbuses" all-weather helicopters carrying up to 200 passengers. When a person left the airbus station he could drive a coin-operated car equipped with radar. The radar equipment of cars would make traffic accidents "almost unheard off\'. Does that sound familiar? If the exert had been accurate it would, because he was writing in 1957. His subject was "The city of 1982". If the professionals sometimes sound like high-school students, it\'s probably because future study is still a new field. Here is an example forfuture study. Economic forecasting, orpredicting what the economy will do, has been around fora long time. But there have been some big mistakes in this field, too. In early 1929, most forecasters saw an excellent future forthe stock market. In October of that year, the stock market had its worst losses ever, ruining thousands of investors who had put their faith in financial foreseers. One forecaster knew that predictions about the future would always be subject to significant errors. In 1957, H. J. Rand of the Rand Corporation was asked about the year 2000, "Only one thing is certain," he answered. " ______"【单选题】
A.In early 1929, most forecasters saw an excellent future forthe stock market.
B.Children born today will have reached the age of 43.
C.Actually, the article was written in 1958 and the question was, "what will life be like in 1978?"
D.So experts are regularly asked to predict accurately.
E.Scientists are 80 percent accurate in predicting the future.
F.The radar equipment of cars would make traffic accidents "almost unheard off\'.
正确答案:B
答案解析:最后一段是总结段,指出预测的不准确性。结束前用调侃的语气写道,要预测2000年将发生的事情,有一件事是不会预测错的:今天出生的婴儿到2000年是43岁(2000-1957=43)。
10、An Intelligent CarDriving needs sharp eyes, keen ears, quick brain, and coordination between hands and the brain. Many human drivers have all. these and can control a fast-moving car. But how does an intelligent car control itself ?There is a virtual driver in the smart car. This virtual driver has "eyes," "brains", "hands" and "feet", too. The mini-cameras on each side of the car are his "eyes," which observe the road and conditions ahead of it. They watch the traffic to the car\'s left and right. There is also a highly automatic driving system in the car. It is the built-in computer, which is the virtual driver\'s "brain". His "brain" calculates the speeds of other moving cars near it and analyzes their positions. Basing on this information, it chooses the right line forthe intelligent cars, and gives instructions to the "hands" and "feets" to act accordingly. In this way, the virtual driver controls his car. What is the virtual driver\'s best advantage? He reacts rapidly. The mini-cameras are sending images continuously to the "brain". It completes the processing of the images within 100 milliseconds. However, the world\'s best driver at least needs one second to react. ______, when he takes action, he needs one more second. The virtual driver is really wonderful. He can reduce the accident rate. considerably on expressway. In this case, can we let him have the wheel at any time and in any place? Experts warn that we cannot do that just yet. His ability to recognize things is still limited. He can now only drive an intelligent car on expressways. 【单选题】
A.So
B.However
C.Besides
D.Therefore
正确答案:C
答案解析:因为前一句已经是however引导的表示“转折关系”的句子,因此不可能接着又出现however引导的另一转折句,所以首先排除B。空白位于句首,而且有一个逗号与句子其他部分隔开,因此空白处应该出现逻辑副词。选项A和D在用做逻辑副词的用法和词义上接近,相互排除,因此答案为C。从空白所在句子的句意上看,该句引出另一信息,因此从句意上判断也需要besides引出表示递进关系的句子。
