1、2000英语专四CLOZEThe difference between a liquid and a gas is obvious ( 26 ) the conditions of temperature and pressure commonly found at the surface of the Earth. A liquid can be kept in an open container and ( 27 ) it to the level of a free surface. A gas forms no free surface but ( 28 ) to diffuse th
2、roughout the space available; it must ( 29 ) be kept in a closed container, as ( 30 )a planets atmosphere. The distinction was a prominent feature of early theories ( 31 )the phases of matter. In the nineteenth century, for example, one theory maintained that a liquid could be “dissolved” in a vapor
3、 without losing its identity, and another theory held that the two phases are ( 32 ) different kinds of molecules (分子). The theories now prevailing ( 33 ) a quite different approach by emphasizing what liquids and gases have in common. They are both forms of matter that have no permanent structure,
4、and they both flow easily. They are fluids.The ( 34 ) similarly of liquids and gases becomes clearly apparent when the temperature and pressure are raised somewhat.( 35 ) a closed container partially filled with a liquid is heated. The liquid expands or ( 36 ), becomes less dense; some of it evapora
5、tes.( 37 ), the vapor above the liquid surface becomes denser as the evaporated molecules are added to it. The combination of temperature and pressure ( 38 ) the densities become equal is ( 39 ) the critical point. Above the critical point the liquid and the gas can no longer be ( 40 ); there is a s

20、rly if we are to participate in the society in which we live we must communicate with other people. A great deal of communicating is performed on a person-to-person basis by the simple means of speech. If we travel in buses, buy things in shops, or eat in restaurants, we are likely to have conversat
21、ions where we give information or opinions, receive news or comment, and very likely have our views challenged by other members of society.Face-to-face contact is by no means the only form of communication and during the last two hundred years the art of mass communication has become one of the domi
22、nating factors of contemporary society. Two things, above others, have caused the enormous growth of the communication industry. Firstly,inventiveness has led to advances in printing, telecommunications, photography, radio and television.Secondly, speed has revolutionised the transmission and recept
23、ion of communications so that local news often takes a back seat to national news, which itself is often almost eclipsed by international news.No longer is the possession of information confined to a privileged minority. In the last century the wealthy man with his own library was indeed fortunate,
24、but today there are public libraries. Forty years ago people used to flock to the cinema, but now far more people sit at home and turn on the TV to watch a program that is being channeled into millions of homes.Communication is no longer merely concerned with the transmission of information. The mod
25、em communication industry influences the way people live in society and broadens their horizons by allowing access to information, education and entertainment. The printing, broadcasting and advertising industries are all involved with informing, educating and entertaining.Although a great deal of t
26、he material communicated by the mass media is very valuable to the individual and to the society of which he is a part, the vast modem network of communications is open to abuse. However, the mass media are with us for better, for worse, and there is no turning back.66.In the first paragraph the wri
27、ter emphasizes the_ of face-to-face contact in social settings.A. Nature B. Limitation C. Usefulness D. creativity67.It is implied in the passage that_.A.local news used to be the only source of information.B. local news still takes a significant place.C. national news is becoming more popular.D. in
28、ternational news is the fastest transmitted news.68.Which of the following statements is INCORRECT?A. To possess information used to be a privilege.B. Public libraries have replaced private libraries.C. Communication means more than transmission.D. Information influences ways of life and thinking.69
29、.From the last paragraph we can infer that the writer is_.A. indifferent to the harmful influence of the mass mediaB. happy about the drastic changes in the mass mediaC. pessimistic about the future of the mass mediaD. concerned about the wrong use of the mass mediaTEXT BThe men and women of Anglo-S
30、axon England normally bore one name only. Distinguishing epithets were rarely added. These might be patronymic, descriptive or occupational. They were, however, hardly surnames. Heritable names gradually became general in the three centuries following the Norman Conquest in 1066. It was not until th
31、e 13th and 14th centuries that surnames became fixed, although for many years after that, the degree of stability in family names varied considerably in different parts of the country.British surnames fall mainly into four broad categories: patronymic, occupational, descriptive and local. A few name
32、s, it is true, will remain puzzling: foreign names, perhaps, crudely translated, adapted or abbreviated; or artificial names. In fact, over fifty percent of genuine British surnames derive from place names of different kinds, and so they belong to the last of our four main categories. Even such a na
33、me as Simpson may belong to this last group, and not to the first, had the family once had its home in the ancient village of that name. Otherwise, Simpson means “the son of Simon”, as might be expected. Hundreds of occupational surnames are at once familiar to us, or at least recognizable after a l
34、ittle thought: Archer, Carter, Fisher, Mason, Thatcher, Taylor, to name but a few. Hundreds of others are more obscure in their meanings and testify to the amazing specialization in medieval arts, crafts and functions. Such are “Day”, (Old English for bread maker) and “Walker” (a fuller whose job it
35、 was to clean and thicken newly made cloth).All these vocational names carry with them a certain gravity and dignity, which descriptive names often lack. Some, it is true, like “Long”, “Short” or “Little”, are simple. They may be taken quite literally. Others require more thinking: their meanings ar
36、e slightly different from the modem ones. “Black” and “White “ implied dark and fair respectively. “Sharp” meant genuinely discerning, alert, acute rather than quick-witted or clever. Place-names have a lasting interest since there is hardly a town or village in all England that has not at some time
37、 given its name to a family. They may be picturesque, even poetical; or they may be pedestrian, even trivial. Among the commoner names which survive with relatively little change from old-English times are “Milton”(middle enclosure) and “Hilton”(enclosure on a hill).70. Surnames are said to be _ in
38、Anglo-Saxon England.A. Common B. Vocational C. Unusual D. descriptive71. We learn from the first paragraph _ for many years after the 13th and 14th centuries.A. family names became descriptive and occupationalB. people in some areas still had no surnamesC. some people kept changing their surnamesD.
39、all family names became fixed in England72. “Patronymic” in the second paragraph is closest in meaning to “formed from _.A. the name of ones father”B. the family occupation”C. ones family home”D. ones family history”73. Which of the following sentences is an opinion rather than a fact?A. hundreds of
40、 occupational names are at once familiar to us.B. “Black” and “White” implied “dark” and “fair” respectively.C. Vocational names carry with them a certain gravity and dignity.D. Every place in England has given its name to a family.TEXT C Since the early 1930s, Swiss banks had prided themselves on t
41、heir system of banking secrecy and numbered accounts. Over the years, they had successfully withstood every challenge to this system by their own government who, in turn, had been frequently urged by foreign governments to reveal information about the financial affairs to certain account holders. Th
42、e result of this policy of secrecy was that a kind of mystique had grown up around Swiss banking. There was a widely-held belief that Switzerland was irresistible to wealthy foreigners, mainly because of its numbered accounts and bankers reluctance to ask awkward questions of depositors. Contributin
43、g to the mystique was the view, carefully propagated by the banks themselves, that if this secrecy was ever given up, foreigners would fall over themselves in the rush to withdraw money, and the Swiss banking system would virtually collapse overnight.To many, therefore, it came like a bolt out of th
44、e blue, when, in 1977, the Swiss banks announced they had signed a pact with the Swiss National Bank (the Central Bank). The aim of the agreement was to prevent to improper use of the countrys bank secrecy laws, and its effect was to curb severely the system of secrecy.The rules which the banks had
45、agreed to observe made the opening of numbered accounts subject to much closer scrutiny than before. The banks would be required, if necessary, to identify the origin of foreign funds going into numbered and other accounts. The idea was to stop such accounts being used for dubious purposes. Also the
46、y agreed not to accept funds resulting from tax evasion or from crime.The pact represented essentially a tightening up of banking rules. Although the banks agreed to end relations with clients whose identities were unclear or who were performing improper acts, they were still not obliged to inform on a
