1、2007 年江苏专转本(英语)真题试卷及答案与解析0 Under proper conditions, sound waves will be reflected from a hillside or other such obstruction. Sound travels at the rate of about one-fifth of a mile per second. If the hill is eleven hundred feet away, it takes two seconds for the sound to travel to the hill and back.
2、Thus, by timing the interval between a sound and its reflection (the echo) , you can estimate the distance to an obstruction. During World War II the British used a practical application of this principle to detect German planes on their way to bomb London long before the enemy was near the target.
3、They used radio waves instead of sound waves, since radio waves can penetrate fog and clouds. The outnumbered Royal Air Force(RAF) always seemed to the puzzled Germans to by lying in wait at the right time and never to be surprised. It was radio echoes more than anything else that won the Battle of
4、Britain. Since the radio waves were used to tell the direction in which to send the RAF planes and the distance to send them (their rage of flight, in other words) , the device was called “radio directing and ranging“ , and from the initials the word “radar“ was coined.1 Sound waves reflected from a
5、 hill can be used to estimate the_.(A)height of the hill(B) speed of sound(C) distance to the hill(D)intensity of sound2 Practical application of this principle resulted in_.(A)new electronic instruments for planes(B) a radio directing and ranging device(C) new radio sets for RAF bombers(D)an electr
6、onic detecting device3 Radar enabled the English to_.(A)detect German planes on their way to London(B) direct the outnumbered RAF planes effectively(C) confuse German bomber pilots(D)both A and B4 It can be inferred from the passage that_.(A)light waves could be used in a device similar to radar(B)
7、radar was a practical application of a well-known principle(C) radar gready increased the effectiveness of the Royal Air Force(D)sound waves are reflected from a hillside under all conditions5 The author of this passage probably intended to explain ,_.(A)exactly how radar works(B) why the British us
8、ed radio waves in their device(C) how radar(word and device)came to be(D)how radar helped the British win the Battle of Britain5 In general, the ancient Romans were a practical people. They cared less about philosophy and pure mathematics than the Greeks did. The Romans were the best of the ancient
9、engineers and architects. They were brilliant students of Greek geometry and trigonometry (三角学) , and they applied their knowledge to the construction of fine bridges, roads, aqueducts(渠道) , and public buildings. They knew about the smelting of iron ore, but they used the iron they produced mainly f
10、or spears, swords, and shields, rather than for building construction. While the Romans accomplished practical wonders, they did very little theoretical scientific thinking. Because of their frequent wars, many of their inventions were no more than improvements in the design of Greek weapons with wh
11、ich they were familiar. There are two reasons for the Roman neglect of philosophy and pure mathematics. First, they were apparently too busy conquering nearby nations and forming them into a rapidly growing empire to waste much time on abstract thinking. Secondly, they were handicapped (妨碍) by the r
12、igidity of their numerical system. (Try to multiply XI by LVII or to divide CXLIII by IX; it simply cannot be done with pencil and paper. ) The Romans did all of their arithmetic on an abacus, the ancient counterpart of the modern computing machine. Their number system discouraged the study of pure
13、mathematics.6 The author calls the Romans “practical“ because they_.(A)cared little about philosophy(B) applied their knowledge to construction(C) saw the necessity for developing theoretical science(D)studied the past and learned from it7 The ancient Romans did not concern themselves with_.(A)theor
14、etical or abstract thought(B) applied mathematics(C) studying(D)either A or C8 In construction, the Romans made extensive use of_.(A)iron ore(B) geometry and trigonometry(C) Greek mathematical thought(D)both B and C9 Many Roman inventions were based on Greek weapons because the_.(A)Greeks had superi
15、or weapons(B) Romans were involved in frequent wars(C) Romans were familiar with many types of weapons(D)Greeks proved themselves inspired inventors10 The author of this passage probably wanted to explain why_.(A)he considered the Romans a practical people(B) Roman architects and engineers were the
16、best in ancient times(C) theoretical thinking is necessary for the growth of a nation(D)the Romans contributed little to philosophical thought10 Professor Barry Wellman of the University of Toronto in Canada has invented a term to describe the way many north Americans interact these days. The term i
17、s “ networked individualism“. This concept is not easy to understand because the words seem to have opposite meanings. How can we be individuals and be networked at the same time? You need other people for networks. Here is what Professor Wellman means. Before the invention of the Internet and e-mai
18、l, our social networks involved live interactions with relatives, neighbors, and colleagues at work. Some of the interaction was by phone, but it was still voice to voice, person to person, in real time. A recent research study by the Pew Internet and American Life Project showed that for a lot of p
19、eople, electronic interaction through the computer has replaced this person-to-person interaction. However, a lot of people interviewed for the Pew study say thats a good thing. Why?In the past, many people were worried that the Internet isolated us and caused us to spend too much time in the imagin
20、ary world of the computer. But the Pew study discovered that the opposite is true. The Internet connects us with more real people than expected helpful people who can give advice on careers, medical problems, raising children, and choosing a school or college. About 60 million Americans told Pew tha
21、t the Internet plays an important role in helping them make major life decisions. Thanks to the computer, “networked individuals“ are able to be alone and together with other peopleat the same time .11 The Pew study was conducted in_.(A)The United States(B) Canada(C) The U. S. and Canada(D)Europe12
22、In this article, a network is a group of connected_.(A)radio or TV stations(B) people(C) computers(D)roads13 Before the invention of the Internet, our connections with people took place mainly(A)in person(B) by phone(C) by letter(D)by e-mail14 Which of the following has happened since the invention
23、of the Internet and e-mail?(A)People are talking on the phone more than ever.(B) Interaction through the computer has replaced a lot of person to person interaction.(C) Americans are turning into hermits.(D)Sixty million Americans have bought computers. 15 Which of the following was NOT one of the d
24、iscoveries of the Pew study?(A)The Internet has put us in touch with more people than expected.(B) People use the Internet to get advice on careers, medical problems, and other questions.(C) For many Americans, the Internet plays an important role in helping them make important decisions.(D)Internet
