1、英语阅读(二)自考题-8 及答案解析(总分:100.00,做题时间:90 分钟)一、BPART ONE/B(总题数:0,分数:0.00)二、B(总题数:0,分数:0.00)三、BPassage One/B(总题数:1,分数:10.00)Electronic computers are among the fastest and most useful instruments for sorting and comparing in use today. Computers provide means for greater speed and accuracy in working with
2、ideas than had previously been possible. With the development of these new tools, it is as if man has suddenly become a millionaire of the mind.Although man has been growing mentally richer ever since he started to think, the electronic computer allows and will continue to allow him to perform treme
3、ndous mental tasks in a relatively short time. Great scientists of the past produced ideas which were the basis for great advances, but their ideas sometimes had to wait for years before they were understood sufficiently well to be of practical use. With the computer, the ideas of todays scientists
4、can be studied, tested, distributed, and used more rapidly than ever before.Old lines and methods of communication do not work easily or efficiently with as much information as we have now. The repeated actions of preparing, sorting, filling, distributing, and keeping track of records and publicatio
5、ns can be as troublesome as calculating. Errors occur because men grow tired and can be distracted.The basic job of computers is the processing of information. For this reason computers can be defined as devices which accept information, perform mathematical or logical operations with the informatio
6、n, and then supply the results of these operations as new information.Although a sharp dividing line between types of computers is not always easy to see, computers are usually divided into two broad groups: digital and analog. Digital computers work by using specific information which is usually in
7、 the form of numbers. Analog computers, on the other hand, usually process continuous information.To explain the differences, let us consider two devices which handle information in a manner similar to the two types of computers. A turnstile, which has a counter attached to it, can help to explain t
8、he way a digital computer works. Each time a person passes through the turnstile, the indicator quickly jumps from one number to another. Each number registered is separate and specific.The continuous change in the level of sand in an hourglass as time passes makes it an analog device. Perhaps the f
9、irst analog computation was the use of graphs for the solution of surveying problems.(分数:10.00)(1).Which of the following statements best summarizes the first paragraph?_ A. Computers have extended the range of our senses. B. Computers have extended the power of our mind. C. Computers have extended
10、the scope of our activities. D. Computers have extended the speed of our reasoning,(分数:2.00)A.B.C.D.(2).With the help of computers, scientists today are able to _. A. have their ideas questioned or shared quickly B. have their new ideas accepted far more widely C. produce their ideas more rapidly D.
11、 understand new information easily(分数:2.00)A.B.C.D.(3).According to the passage, computers are mainly used to do the following EXCEPT _. A. performing math operations B. processing information C. supplying solutions D. storing technical data(分数:2.00)A.B.C.D.(4).The digital computers are different fr
12、om analog computers because _. A. they process continuous information B. they process specific information C. they record separate numbers D. they produce vivid pictures(分数:2.00)A.B.C.D.(5).The tone the writer uses in this passage is _. A. critical B. analytical C. subjective D. objective(分数:2.00)A.
13、B.C.D.四、BPassage Two/B(总题数:1,分数:10.00)Q. Theres a lot of talk about putting up manned orbital stations. What does this mean, concretely?A. It is very important to have scientific stations in space. A space telescope with a mirror slightly over six and a half feet in diameter will be placed in orbit,
14、 and there will be more and more of these. A few years ago, our group at Saclay, in collaboration with a number of other European Laboratories, orbited a telescope that revolutionized our knowledge of gamma ray emissions by celestial objects.Life aboard manned space stations wont be as exciting as w
15、e might suppose. It will probably be comparable to the life people lead aboard deep-sea oil rigs.Q. What scientific interest will these stations offer?A. Observation is much more precise beyond the atmosphere, because the sky is darker. You see many more stars and objects that are concealed by the e
16、arths luminescence.Q. What objects?A. We know pretty well how stars are born because we can observe them. Two or three new stars appear in our galaxy every year. But nearly all the galaxies were born at the same time, when the universe was constituted 15 billion (light) years ago. No new ones are th
17、ought to exist.To observe the birth of a galaxy that happened so long ago, you have to see a very long way. At present we can go back 10 to 12 billion years. We have to go a bit farther back still, and maybe catch them in the act of birth. Distant objects are necessarily very dim, so ideal condition
18、s are needed to observe them. Orbital stations provide such conditions.Q. Would orbital stations be choice places from which to try to communicate with extraterrestrial intelligences?A. Not particularly through radio communication, except on certain wave lengths that are absorbed by the atmosphere.
19、But as points of departure for exploration theyll be very useful.Q. How far would such exploration go?A. In 1989 the satellite Voyager 1I will reach Neptune after a journey of three and a half years. In addition, five probes were sent to rendezvous with Halleys comet. So exploration of the solar sys
20、tem is more or less under way. Weve put people on the moon, sent probes to Mars and Venus, lofted satellites near the sun (within a few tens of millions of miles), and one satellite even left the solar system a few years ago.But visiting the stars is something else again. Light takes four years to r
21、each the nearest stars, so you can see that it would take a satellite hundreds of thousands of years.Of course, if the earth were to become overpopulated, we can imagine sending families in space vessels to colonize the nearest stars. But its their great-great-great-grand-children who would finally
22、reach those stars. And they wouldnt even know where to stop.(分数:10.00)(1).The writer compares the life on a space station to the one on a deep-sea oil rig in order to show _. A. excitement in the wild B. dull environment C. hard living conditions D. the sameness in operation(分数:2.00)A.B.C.D.(2).Orbi
23、tal stations provide an ideal condition to observe a galaxy because _. A. we are close to it in space B. we can go back 10 to 12 billion years C. a galaxy appears dimmer in that environment than on earth D. a galaxy appear brighter in that environment than on earth(分数:2.00)A.B.C.D.(3).In Para. 7, th
24、e sentence “No new ones are thought to exist“ means _. A. nobody believes that there is any new galaxy to be found soon B. nobody believes that any new galaxy exists now C. people are wrong to believe that new galaxies will appear D. people believe that the galaxies are very old now(分数:2.00)A.B.C.D.
