    1、大学英语三级 A 级-108 及答案解析(总分:100.00,做题时间:90 分钟)一、Part Reading Compr(总题数:0,分数:0.00)二、Task 1(总题数:2,分数:20.00)Scientists around the world have been studying the warming of waters in the Pacific Ocean known as E1 Nino. The appearance of E1 Nino is known to affect the weather around the world. Scientists still

    2、 do not completely understand it. Yet they now find they can use it to tell about the future in different areas of the world. One example is the work of two scientists at Columbia University in New York, Mark Cane and Gordon Eshel. A scientist of Zimbabwe, Roger Buckland worked with them. They have

    3、found that when E1 Nino appears, Zimbabwe has little or no rain. This means corn crops in Zimbabwe are poor. One E1 Nino was in 1991 to 1993. That was when southeastern Africa suffered a serious lack of rain. The scientists wrote about their recent work in the publication Nature. Their computer prog

    4、ram can tell when an El Nino will develop up to a year before it does. They suggest that this could provide an effective early warning system for southern Africa, and could prevent many people from starving.(分数:10.00)(1).People know E1Nino as: 1 in the Pacific Ocean.(分数:2.00)(2).The appearence of E1

    5、 Nino is known to affect 1 around the world.(分数:2.00)(3).The purpose of studying E1 Nino: 1.(分数:2.00)(4).E1 Nino“s direct influence on Southern Africa: 1.(分数:2.00)(5).Best title of this passage: 1.(分数:2.00)A little over two centuries ago this was uncultivated territorya vast almost unknown continent

    6、. It is a land of amazing scenery and of astonishing beauty, above and below the waves. It is, of course, Australia. The first settlement here was named after Lord Sidney, the British Home Secretary at the time. Today Sidney is the largest city in a powerful and prosperous nation. It is home to more

    7、 than four and a half million people. Though Britain and Australia are oceans apart physically, their relationship remains strong. Both are members of the Commonwealth and their people share a common head of state, a language, a political system and a whole cultural heritage. For centuries, European

    8、s have suspected there was a great southern continent, and adventurers longed to seeking it. But history credits the English seaman Captain James Cook with the voyage of “Discovery“ that finally put Australia on the map. More than two centuries ago his ship “The Endeavor“, first approached the land

    9、claiming this continent for Britain. The voyage was recently recreated. Britain and Australia keep strong connections as business partners and through the many cultural and family connections. Young Australians fought and died alongside the British and the other allies in two world wars. Today, youn

    10、g Australians regularly head for Europe and especially the UK. Not much seems to happen in Australia“s distant areas. There“s just miles and miles of almost undeveloped land. There“s the bird life of course and you won“t get very far without seeing kangaroos, or if you are lucky, koala bears. Apart

    11、from that and farming there doesn“t seem to be much else. But there is money being made in this uncultivated land. An old enterprise has recently become one of Australia“s fastest growing industries. Wine exports have boomed beyond anyone in Australia“s wildest dreams. They“ve grown from less than 8

    12、 million litres to some 130 million, in only ten years. So there is rather more to the distant areas than wildlife and dusty roads.(分数:10.00)(1).The conditions of Australia over 200 years ago: 1.(分数:2.00)(2).The population of Sydney is more than: 1.(分数:2.00)(3).The person who first put Australia on

    13、the map: 1.(分数:2.00)(4).The country Australia established a close relationship with: 1.(分数:2.00)(5).One of Australia“s fastest growing industries: 1.(分数:2.00)三、Task 2(总题数:4,分数:40.00)ATransducer BMicrophone CPickup DLoudspeaker EAmplifier FRemote controller GOutput jack HVolume control IFM/AM Band sw

There is no smoke to soil the passengers“ clothes and the

    20、cushions in the train. Because they carry no heavy loads of coal and water, these trains can start and stop with less waste of power. In a station they are silent: there“s no steam to produce noise to deafen the passengers. Because of these advantages, electric trains are replacing steam trains in m

    21、any countries. But an electric train has to pick up its current as it travels along. None of our present batteries would be satisfactory enough to drive it fast and at a reasonable cost; and besides, batteries are heavy. Therefore, before an electric service is started, the line must be charged with

    22、 electricity. The necessary current may be carried in wires over the line, and the railway engine may collect it by means of a spring framework on the roof pressing upwards against the wire. Or the current may be carried in a third rail, just outside one of the normal rails. Metal shoes outside the

    23、wheels of the train then press downwards on this rail. The current passes through them to the switches and the motors. In each case the return path of the current is through the wheels of the train and the ordinary rails on which they run. These are the commonest systems used, though there are other

    24、s. Either direct or alternating current may be used for driving electric trains, and the voltages vary greatly in different parts of the world. Usually a high voltage is carried by the overhead-wire system, and the third rail has current at a much lower voltage. This is because of the danger that a

    25、man on the line might touch the electric rail, but he cannot touch an overhead wire. Even so, it is very dangerous indeed to touch an electric rail; and in places where men walk across or along the line, the rail is commonly protected by wood at the two sides. Enough has been said to show the advant

    26、ages and some of the problems of the electric railways. Electric trains, clean and quiet, are providing excellent service for the public.(分数:10.00)(1).Why are electric trains silent in a station? Because they give off 1.(分数:2.00)(2).Why are present batteries not satisfactory to drive electric trains

    27、? They are 1.(分数:2.00)(3).When the necessary current is carried in wires over the line, how does railway engine collect it?(分数:2.00)(4).Why does an overhead wire carry current at a high voltage? Because 1.(分数:2.00)(5).What“s the best title of this passage?(分数:2.00)Like it or not, the world has embar

    28、ked on a microelectronic revolution that is expected to surpass the industrial revolution in the breadth and speed of cultural and technological changes it makes. Pushed by the development of the transistor in the late 1940s, microelectronics first began to make its mark in 1959 with the introductio

    29、n of the integrated circuit (IC)a package of transistor circuitry wired together on a small silicon chip. In time, other electronic components such as diodes and resistors made their appearance in chips. But a major breakthrough came in 1971 when microprocessors came into being that essentially offe

    30、red the entire central processing unit of a computercomplex circuitry to process data and handle computationson a silicon chip. Today the most densely packed ICs feature nearly 100,000 components on a chip five millimeters across, wired together with aluminum conductors roughly 30 times thinner than

    31、 a human hair. Within three decades, a roomful of vacuum tubes; wires and other components have been reduced to the size of a cornflake. And the process is not over yet. Chip manufacturers are sure that they will soon be able to produce integrated circuits containing at least one million components.

    32、 Some scientists describe the microelectronics age as the second industrial revolution. They say that man is just at the beginning of mechanizing intellectual activity. They suggest that this, in fact, marks the profound difference between the microelectronic and industrial revolutions. The developm

    33、ent of industrial technology largely strengthened human physical capabilities, enabling people to harness more energy, process and shape materials more easily, travel faster, and so on while the development of microelectronics extends mental capabilities, enabling electronic “intelligence“ to be clo

    34、sely related to a wide range of products and processes. In fact no technology in history has had such a broad range of potential applications. Increasingly sophisticated computer-controlled robots are entering industry to cut down production costs, time and labor requirements.(分数:10.00)(1).What do y

    35、ou expect the microelectronic revolution will bring about? 1 and 2.(分数:2.00)(2).When did microelectronics first begin to be widely accepted? When 1.(分数:2.00)(3).What is the profound difference between microelectronic and industrial revolutions? The former extends man“s 1 while the latter strengthens

    36、 man“s 2 ones.(分数:2.00)(4).What is the main advantage of microelectronic technology?(分数:2.00)(5).What is the theme of this passage?(分数:2.00)Sometimes teens need to have some time away from their families. They may want to move out of the family home for a while. Many parents will say no to this dema

    37、nd. But experts say it might be a good idea to let your teens live with a friend or relative. “It was the break I needed at the time,“ said Richard Lerner. He is talking about the time he spent living with his grandmother when he was 15. “It allowed me to be a different person than I was with my par

    38、ents,“ Lerner said. He now heads the Institute for Children, Youth and Families at Michigan State University. Experts say teens living away from their families can test new ways of thinking and getting along with people. They may see new solutions to problems. This is different from running away, th

    39、e experts stress. Runaways are often fleeing serious problems. Some teens who want some time away from family attend a structured summer program. Others live for a while with a relative or with the family of a friend. If there is a conflict at home, having a teen live elsewhere can benefit other fam

    40、ily members. It gives everyone space to develop better relationships. Josepy Kett teaches history at the University of Virginia in Charlottesville. He says living at home until the late teen years has become the norm only in recent times. “In the 17th century, children were often sent to live in oth

    41、er people“s homes when they were about 10 to 11,“ he said. Peter Sheras teaches education at the University of Virginia. He said parents should listen when a child wants to move out. They should try to find out why the child wants some time away. Often, parents can help the child find a safe place t

    42、o stay during that time. In other cases, they can meet the child“s needs at home.(分数:10.00)(1).What is parents“ attitude when children want to move out?(分数:2.00)(2).What do experts suggest the parents should do when children seriously disagree with them? To let 1.(分数:2.00)(3).What does “structured“

    43、(Para.7) in this passage mean?(分数:2.00)(4).What did teens often do in history?(分数:2.00)(5).Who worries most about children“s living away from home?(分数:2.00)If you come to the town of Medway, Rochester in England between May 28 and June 6, you will find you are back to the Victorian days. The town is

    44、 crowded with people as so many people come to the town from all over Britain. They all wear clothes of those days: men with tall hats and women in long skirts. They are celebrating the yearly Dickens Festival because it was here that Charles Dickens spent his childhood, held his wedding, and died n

    45、ot far from. A special train called “Mr. Pickwick“ sends people from London to Rochester. Then at the railway station there, people will see all the characters from Dickens“ novels “come alive“ and walk through the town. A lot of scenes from Dickens“ novels are performed, not only on stages, but in

    46、the streets and bars. The most interesting place is, of course, the Dickens Center, where people can see replicas of the 19th century: how Charles Dickens lived. The climax of the Dickens Festival is in the church where people hold service to commemorate the great writer.(分数:10.00)(1).Why is Dickens

    47、 Festival held every year? In 1.(分数:2.00)(2).What do most of the visitors wear during the Festival?(分数:2.00)(3).Where can you see all the characters from Dickens“ novels?(分数:2.00)(4).How many days does the Festival last?(分数:2.00)(5).Who is Mr. Pickwick?(分数:2.00)大学英语三级 A 级-108 答案解析(总分:100.00,做题时间:90
