1、考研英语-试卷 116及答案解析(总分:142.00,做题时间:90 分钟)一、Use of English(总题数:2,分数:80.00)1.Section I Use of EnglishDirections: Read the following text. Choose the best word(s) for each numbered blank and mark A, B, C or D.(分数:40.00)_In the United States today, coffee is a more popular drink (1)_ tea, but tea played (2
2、)_ interesting part in the history of the United States. Before they won their (3)_ from Britain, the colonists were forced to (4)_ taxes on many goods imported into America. The tax money was (5)_ to support colonial governors and officials sent to the colonies by the British. In 1770 the British P
3、rime Minister had repealed most of the taxes, but King George (6)_ on retaining the tax (7)_ tea. The King saw the tax as a (8)_ of the British right to tax the colonies. American merchants (9)_ smuggled nine-tenths of America“s tea into the country and (10)_ paying the taxes. (11)_ the tax savings,
4、 the price of tea remained expensive due. to (12)_ shipping costs. When the British Parliament (13)_ a new law which would allow British companies to import tea more (14)_ than American shipping companies, the (15)_ were alarmed and they (16)_ a protest. In Boston citizens and merchants, who (17)_ d
5、isguised as Indians, boarded a British ship and (18)_ $15,000 worth of tea into the harbor. This protest (19)_ Great Britain is known as the Boston Tea Party. It was one of the earliest acts of (20)_ against British rule.(分数:40.00)A.fromB.againstC.comparedD.thanA.anB.aC.butD.andA.independenceB.inter

8、D.assurance二、Reading Comprehensio(总题数:10,分数:58.00)2.Section II Reading Comprehension_3.Part ADirections: Read the following four texts. Answer the questions below each text by choosing A, B, C or D._Nuclear fission is the splitting of the nucleus of an atom. Only a few elements are suitable for use
9、in this way, the most important ones being Uranium-235, Uranium-233, and Plutonium-239. When a nucleus of one of these elements is struck by a free neutron it breaks down into two lighter nuclei which fly apart at high speed, colliding with surrounding atoms. Their kinetic energy is converted into h
10、eat energy. At the same time, two or three free neutrons are released and one of them enters the nucleus of a neighbouring atom, causing fission to occur again; and so on. The reaction spreads very quickly, with more and more heat energy released. This is called a “chain“ reaction because the splitt
11、ing of each nucleus is linked to another, and another and another. If this reaction takes place in an atomic bomb, where nothing is done to slow it down, the result is a violent explosion that can destroy a town in a few seconds. Fission can also, however, take place within a construction called a n
12、uclear reactor, or atomic pile. Here the highly fissile material (U-235, U-233, Pu-239) is surrounded by a substance that is non-fissile, for instance graphite. This material is called a moderator. The neutrons lose some of their energy and speed through colliding with the atoms of the moderator. En
13、ergyheat energyis still created on an enormous scale, but no expansion takes place. The moderator has another function: by slowing down the speed of the free neutrons, it makes it more likely that one of them will collide with the nucleus of a neighbouring atom to continue the chain reaction. The ch
14、ief advantage of nuclear energy is that it does not depend on any local factors. A nuclear reactor, unlike an oil-well or a coalmine, does not have to be sited on top of a fossil-fuel source; unlike the solar energy unit, it does not have to go out of production when the sun is not shining; unlike h
15、ydro-electric power, it does not depend on a large flow of water which may be reduced during some seasons of the year. With an atomic power station, the only limiting factor is that of safety. In the opposite process, nuclear fusion, two nuclei come together, to form a new nucleus of a different kin
16、d and this process also releases energy on an enormous scale. Fusion can only occur under conditions of very great heatat least 50,000,000 degrees Celsius. (The temperature at the centre of the sun is estimated as 130,000,000 degrees Celsius.) A fusion reaction on earth has already been createdthe h
17、ydrogen bomb. This is an uncontrolled reaction. It is not yet possible to produce a controlled fusion reaction that can be used for the production of useful energy. Nuclear energy can be thought of as a kind of square, three of the quarters of the square are known and used, but the fourth cannot yet
18、 be used.(分数:10.00)(1).Which of the following headings is that of Paragraph Two?(分数:2.00)A.Nuclear FusionB.The Nuclear Fission Chain ReactionC.Uncontrolled and Moderated Nuclear ReactionsD.The Advantages of Nuclear Energy(2).The aim of a nuclear reactor is _.(分数:2.00)A.to establish a controlled chai
19、n reaction in low concentrations of fissile materialB.to absorb neutrons travelling at a particular speedC.to cause a rapid chain reaction in order to release the greatest amount of energyD.to last the chain reaction forever(3).Destructive weapons can be obtained from _.(分数:2.00)A.nuclear fusionB.nu
20、clear fissionC.both nuclear fusion and nuclear fissionD.nuclear splitting(4).In nuclear fusion, two nuclei come together and _.(分数:2.00)A.form a new nucleusB.both splitC.give off free neutronsD.reduce energy(5).Which of the following statements is incorrect?(分数:2.00)A.Few elements are suitable for u
21、se as atomic fuel.B.An atomic power station can supply the same quantity of energy all the year round.C.A hydro-electric power station can be built anywhere.D.Graphite is a non-fissile material.The period of adolescence, i.e., the period between childhood and adulthood, may be long or short, dependi
22、ng on social expectations and on society“s definition as to what constitutes maturity and adulthood. In primitive societies adolescence is frequently a relatively short period of time, while in industrial societies with patterns of prolonged education coupled with laws against child labor, the perio
23、d of adolescence is much longer and may include most of the second decade of one“s life. Furthermore, the length of the adolescent period and the definition of adulthood status may change in a given society as social and economic conditions change. Examples of this type of change are the disappearan
24、ce of the frontier in the latter part of the nineteenth century in the United States, and more universally, the industrialization of an agricultural society. In modern society, ceremonies for adolescence have lost their formal recognition and symbolic significance and there no longer is agreement as
