1、2000年 一The 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 throughout the

2、 space available; it must (29) be kept in a closed container, as (30) a planet's 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 o f molecules(分子). The theories now prevailing (33) a quit e different approach by emphasizing what liquids and gases have in common. They are both forms of matter that have no permanent structure and t

4、hey both flow ea silly. 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 evaporates

5、. (37), the vapor above the liquid surface becomes dense r as the evaporated molecules are added to it. The combination of temperature and d 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

12、s. He should be willing to work ( 28 )is own, often at high speeds, but should be humble enough to consult others ( 29 )his own knowledge not always prove adequate to the task in hand. He should be able to type fairly quickly and accurately and, if he is working mainly for publication, should have m

13、ore than a nodding ( 30 )with printing techniques and proof-reading. If he is working basically as an information translator, let us say, for an industrial firm, he should have the flexibility of mind to enable him to ( 31 )rapidly from one source language to another, as well as from one subject-mat

14、ter to another, since this ability is frequently ( 32 )of him in such work. Bearing in mind the nature of the translators worksite. The processing of the written word, it is, strictly speaking, ( 33 )that he should be able to speak the language he is dealing with. If he does speak them, it is an adv

It is, (36), desirable that he should have an approximate idea about the pronunciation of his source languages even if this is restricted to ( 37 )how proper names and place names are pronounced.

19、ople thinking about the origin of language for the first time usually arrive at the conclusion that it developed gradually as a system of grunts, hisses and cries and ( 26 ) a very simple affair in the beginning.( 27 ), when we observe the language behaviour of ( 28 )we regard as primitive cultures,

20、we find it ( 29 )complicated. It was believed that an Eskimo must have the tip of his tongue a vocabulary of more than 10,000 words ( 30 ) to get along reasonably well, much larger than the active vocabulary of an average businessman who speaks English.( 31 ), these Eskimo words are far more highly

21、infleeted(词尾变化的) than ( 32 ) of any of the well -known European languages,for a( 33 )noun can be spoken or written in ( 34 ) hundred different forms, each ( 35 )a precise meaning different from that of any other.The forms of the verbs are even more( 36 ). The Eskimo language is, therefore,one of the

22、 most difficult in the world to learn,( 37 ) the result that almost no traders or explorers have( 38 )tried to learn it. Consequently , there has grown up, in communication between Eskimos and whites, a jargon ( 39 )to the pidgin English used in Old China, with a vocabulary of from 300 to 600 uninfl

23、ected words. Most of them are derived from Eskimo but some are derived from English, Danish,Spanish, Hawaiian and other languages. It is this jargon that is usually( 40 ) by travellers as “the Eskimo language”.26. A. must be   B. must have been C. ought to be    D. should be 27. A. Ho
