During the past hundred years，the car，the radio，the cinema，and now television have produced great 26 in the amusements with which people pass their 27 time. A 28 years ago，people were in the habit of making their own amusements. When a group of people 29 ，they talked，played cards or other games，or went out riding，shooting，or walking together. Most people could sing a little，or play some musical instrument reasonably well；so at a party the guests amused each other. 30 ，conversation(聊天 )was an 31 ； amusing conversation could 32 people happy for hours. As for games such as football and cricket(板球)，people were also in the habit of playing them themselves. Most of them did not play very well，but they 33 themselves and their friends.

Why play football with players who 35 very good when you can go to 36 some of the best players playing football in your country? 37 an important match? Few people do this. You may just sit comfortably 38 and watch the game without the 39 of going outside.

He wrote a book about them called Principles of Geology (地质学). The earth，according to Lyell，was not only thousands of years old， it was millions of years old.As to (关于 ) the common belief that changes in the earth’s surface happen suddenly because of a single earthquake or flood，he said that this might happen once in a while，but usually these changes took place very slowly. He believed that the surface of the earth had been changing from the beginning of time. The changes，he said，were caused by the long-term action of the winds and seas，and by forces such as volcanoes breaking out under the earth’s surface. Once in a great while he thought，a mountain might appear for the first time after an earthquake. But usually mountains would rise slowly and steadily. Professor Henslow was interested in Lyell’s ideas， but he did not actually believe them. Charles Darwin could not make up his mind about them. But they set him thinking along lines which would later change the beliefs of thoughtful people all over the world. At Cambridge，Charles Darwin studied just enough to pass the examination，and received his college degree in 1831.During this time，he had become more and more interested in geology. At the end of the school year，he went to North Wales with one of his teachers to examine the rock formations (构成) and to search for fossils (化石). Fossils are the remains of ancient living things. They are usually found fixed in rocks in the earth’s crust (地壳 ). Fossils may be of animals，such as fish，insects，birds，or humans. They may be of plants from tiny leaves to huge trees. When a living creature dies，it usually decays (腐烂)or is eaten by animals. However，if it sinks into a riverbed (河床) or is quickly covered by the blowing sands of a desert storm， the bones are kept up in the earth. Over many years the soft inner parts of a bone disappear，leaving the inside hollow (空的 ). Water containing mineral enters into the hollow. Slowly the mineral hardens and makes the bone hard and heavy，like stone. 46.According to Charles Lyell，it is mainly that the earth has been formed like today’s shape. A.from the beginning of time B.past some experiences of big flood C.over a very long period of years D.because of several big earthquakes 47.Charles Lyell believed the fact that a mountain is formed . A.more by seas than by volcanoes B.more slowly than suddenly C.more by an earthquake than by winds D.more steadily than quickly 48.Unlike Professor Henslow，Charles Darwin . A.never thought Lyell’s ideas were right B.did made up his mind not to accept Lyell’s ideas C.thought about what the world were then thinking about D.thought over Lyell’s ideas and developed them 49.The main purpose of Darwin’s going to North Wales was to . A.make a study of fossils B.appreciate the rock information C.to do research work into dead animals D.look for plants from tiny leaves to huge trees 50.In which order are fossils formed? a.A living thing sinks into a riverbed or sands. b.Water goes into a bone hollow together with mineral. c.Something soft in a bone disappears. d.The hardened mineral makes the bone hard. e. The bone becomes hollow inside. A.a b c d e B.c a b e d C.a c e b d D.e c d b a B Under proper conditions，sound waves are reflected from a hillside or other such obstruction (障碍物). Sound travels at a speed 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. Thus by measuring the time between a sound and its reflection the echo (回声)，you can calculate (计算) the distance to an obstruction. During World War Ⅱ the British made a practical use of this rule to discover German planes on their way to bomb (轰炸) London long before the enemy was near the object. They used radio waves instead of sound waves ， since radio waves can pass through fog and clouds. The outnumbered Royal Air Force (RAF)(皇家空军) always seemed to be lying in wait at the right time and the puzzled Germans never to be surprised. It was radio echoes more than anything else that won the Battle of 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 range (距离范围) of flight，in other words］，the device (装置) was called radio directing and ranging， and from the first letters the word radar (雷达 ) was formed. 51.Sound waves reflected from a hill can be used to calculate the . A.speed of sound B.time between a sound and its echo C.height of the hill D.distance to the hill 52.The British used radio waves because they . A.were more exact than sound waves B.could not be discovered C.could pass through fog and clouds D.were easier to use than sound waves 53.Practical use of radio waves brought about . A.new machines for planes B.a radio directing and ranging device C.new radio sets for RAF bombers D.a discovering device 54.Radar allowed British to be able to . A.discover German planes on their way to London B.direct the outnumbered RAF planes effectively C.kill German bomber pilots D.both A and B 55.The author of this passage mainly wanted to explain . A.exactly how radar worked B.why the British used radio waves in their device C.how radar (word and device) came into being D.how radar helped the British win the battle C You’ve probably heard a lot about the Internet，but what is it? The Internet is a computer network that uses the telephone system to link together millions of computers around the world. Maybe that doesn’t sound exciting，but once you’re connected to the Internet，there are lots and lots of different things you can do. You can send electronic messages or “E-mail” to your friends (as long as they’re on the Internet too)，or you can sort (挑出，拣出) through all sorts of information on something called the World Wide Web. You don’t need to know how the Internet works in order to use it，but if you understand the basics，it may help you solve any technical problem you have—and of course you can impress your friends with your Net knowledge! You may think that your telephone is just for talking. But as long as you have the right equipment，you can use a telephone line to transmit computer data (数据) as well as sounds. If you plug your computer into the telephone system it can receive information from and send information to other computers (as long as they are plugged into the telephone system too). Computer data is made up of electronic signals ( 讯息 ). A computer language called TCP/IP(which stands for Transmission Control Protocol/Internet Protocol， if you like to know these things) is used to move computer data around the Internet. Many of the links ， for example，those which send out computer data across the Atlantic Ocean，are special fiber optic cables (光导纤维电缆)，fiber optic cables use light to send out information. They can carry a lot more data than an ordinary telephone line and they send it a lot faster! 56.Which of the following is true? A.The passage tells us something about the Internet. B.The passage tells the reader how to use telephone line. C.If we want to use the Internet，we must know how it works. D.E-mail has no use. 57.If your telephone is for talking，but you want to go on the Internet. What should you do? A.Nothing. B.To have the right equipment，then use a telephone line to send out computer data as well as sounds. C.Ask your friend for help. D.Persuade someone not to use the telephone. 58.If you have some basic knowledge of the Internet working，the writer of the text would most probably consider it . A.possible B.useless C.unimportant D.helpful 59.The underlined word “transmit” means . A.send out B.give away C.give up D.leave out 60.What isn’t mentioned in the passage? A.What the Internet is. B.How big the Internet is. C.Where you’d better go on the Internet. D.What the E-mail is. 答 题 栏 题号 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 答案 题号 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 答案 题号 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 答案 题号 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 答案 第Ⅱ卷(共 20分) 第四部分：写作(共两节，满分 20分) 第一节：短文改错(共 10小题；每小题 1分，共 10分) 此题要求改正所给短文中的错误。对标有题号的每一行作出判断。如无错误，在该行右 边横线上划一个勾(√)；如有错误(每行只有一个错误)，则按下列情况改正： 该行多一个词：把多余的词用斜线(＼)划掉，在该行右边横线上写出该词，并也用斜 线划掉。 该行缺一个词：在缺词处加一个漏字符号(∧)，在该行右边横线上写出该加的词。 该行错一个词：在错的词下面划一横线，在该行右边横线上写出改正后的词。 注意：原行没有错的不要改。 The plastic shopping bags may soon be a thing of past. 61.
