1、2021年上海考研英语考试真题卷（7）本卷共分为1大题50小题，作答时间为180分钟，总分100分，60分及格。一、单项选择题（共50题，每题2分。每题的备选项中，只有一个最符合题意） 1.Text 3When the first white men arrived in Samoa, they found blind men, who could see well enough to describe things in detail just by holding their hands over objects. In France, Jules Roman tested hundred
2、s of blind people and found a few who could tell the difference between light and dark. He narrowed their photosensitivity(感光灵敏度) down to areas on the nose or in the finger tips. In 1960 a medical board examined a girl in Virginia and found that, even with thick bandages over her eyes, she was able
3、to distinguish different colours and read short sections of large print.Rosa Kuleshova, a young woman in the Urals, can see with her fingers. She is not blind, but because she grew up in a family of blind people, she learned to read Braille to help them and then went on to teach herself to do other
4、things with her hands. She was examined by the Soviet Academy of Science, and proved to be genuine, Shaefer made an intensive study with her and found that, securely blindfolded with only her arms stuck through a screen, she could tell the difference between three primary colours. To test the possib
5、ility that the cards reflected heat differently, he heated some and cooled others without affecting her response to them. He also found that she could read newsprint under glass, so texture was giving her no clues. She was able to identify the colour and shape of patches of light projected on to her
6、 palm or on to a screen. In rigidly controlled tests, with a blindfold and a screen and a piece of card around her neck so wide that she could not see round it, Rosa read the small print in a newspaper with her elbow. And, in the most convincing demonstration of all, she repeated these things with s
7、omeone standing behind her pressing hard on her eyeballs. Nobody can cheat under this pressure.Which of the following statements is true（）AThe men in Samoa were not quite blind.BA girl called Virginia could read newsprint even when she was blindfolded.CRosa' s ability to see was confined to her
8、fingers.DThe result of the last test on Rosa was least doubtable.2.Text 3When the first white men arrived in Samoa, they found blind men, who could see well enough to describe things in detail just by holding their hands over objects.

15、 eyeballs.DTo work from behind a screen, blindfolded and with a card round her neck.3.Text 4The U.S. government has recently helped people learn more about the dangers of earthquakes by publishing a map.

16、ere government is spending a great deal of money and is working hard to help discover the answer to these two questions:1. Can we predict earthquakes2. Can we control earthquakesTo answer the first question, scientists are looking very closely at the most active fault systems in the country, such as
17、 the San Andreas fault in California. A fault is a break between two sections of the earth’s surface. These breaks between sections are the places where earthquakes occur.Scientists look at the faults for changes which might show that an earthquake was about to occur. But it will probably be m
18、any years before we can predict earthquakes accurately and the control of earthquakes is even farther away.Nevertheless, there have been some interesting developments in the field of controlling earthquakes. The most interesting development concerns the Rocky Mountain Arsenal earthquakes. Here water
19、 was pat into a layer of rocks 4,000 metres below the surface of the ground. Shortly after this injection of water, there was a small number of earthquakes. Scientists have decided that the water which was injected into the rocks worked like oil on each other. When the water oiled the fault, the fau
20、lt became slippery and the energy of an earthquake was released.Scientists are still experimenting at the site of these earthquakes. They have realized that there is a connection between the injection of the water and the earthquake activity. They have suggested that it might be possible to use this
21、 knowledge to prevent very big, destructive earthquakes, that is, scientists Could inject some kind of fluid like water into faults and change one big earthquake into a number of small, harmless earthquakes.What can be said about the experiments at Rocky Mountain Arsenal（）AThey have no practical val
22、ue in earthquake prevention.BThey may have practical value in earthquake prevention.CThey are certain to have practical value in earthquake prevention.DThe article does not say anything about their practical value in earthquake prevention.4.Text 4The U.S. government has recently helped people learn
