17、mpede （ D） ascribe 二、 Cloze 30 People 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【 1】 a very simple affair in the beginning.【 2】 , when we observe the language behaviour of【 3】 we re

18、gard as primitive cultures, we find it【 4】 complicated. It was believed that an Eskimo must have at the tip of his tongue a vocabulary of more than 10,000 words【 5】 to get along reasonably well, much larger than the active vocabulary of an average businessman who speaks English.【 6】 , these Eskimo w

19、ords are far more highly inflected (词尾变化的 ) than【 7】 of any of the well-known European languages, for a 【 8】 noun can be spoken or written in【 9】 hundred different forms, each【 10】 a precise meaning different from that of any other. The forms of the verbs are even more【 11】 The Eskimo language is, t

20、herefore, one of the most difficult in the world to learn,【 12】 the result that almost no traders or explorers have【 13】 tried to learn it. Consequently, there has grown up, in communication between Eskimos and whites, a jargon【 14】 to the pidgin English used in Old China, with a vocabulary of from

21、300 to 600 uninflected words. Most of them are derived from Eskimo but some are derived from English, Danish, Spanish, Hawaiian and other languages.lt is this jargon that is usually【 15】 by travellers as “the Eskimo language“. （ A） must be （ B） must have been （ C） ought to be （ D） should be （ A） How

22、ever （ B） Therefore （ C） Probably （ D） Undoubtedly （ A） whose （ B） that （ C） which （ D） what （ A） conspicuously （ B） usually （ C） surprisingly （ D） sufficiently （ A） so as （ B） so that （ C） as such （ D） as well as （ A） However （ B） Moreover （ C） Though （ D） Therefore （ A） the others （ B） all others

23、（ C） these （ D） those （ A） single （ B） singular （ C） plural （ D） compound （ A） some （ B） several （ C） various （ D） varied （ A） getting （ B） causing （ C） having （ D） owning （ A） endless （ B） multiple （ C） uncountable （ D） numerous （ A） with （ B） for （ C） owing to （ D） as （ A） still （ B） indeed （ C） j

24、ust （ D） even （ A） alike （ B） similar （ C） related （ D） relevant （ A） referred to （ B） talked about （ C） spoken （ D） told 46 【 C10】 （ A） stopped （ B） eased （ C） relieved （ D） improved 46 Motorways are, no doubt the safest roads in Britain. Mile【 41】 mile, vehicle for vehicle, you are much【 42】 likel

25、y to be killed or seriously injured than on an ordinary road. On【 43】 hand, if you do have a serious accident on a motorway, fatalities are much more likely to【 44】 than in a comparable accident【 45】 on the roads. Motorways have no【 46】 bends, no roundabouts or traffic lights and【 47】 speeds are muc

26、h greater than on other roads. Though the 70 mph limit is【 48】 in force, it is often treated with the contempt that most drivers have for the 30 mph limit applying in built up areas in Britain. Added to this is the fact that motorway drivers seem to like traveling in groups with perhaps【 49】 ten met

27、res between each vehicle. The resulting horrific pile-ups【 50】 vehicle stops for some reason mechanical failure, driver error and so on have become all【 51】 familiar through pictures in newspapers or on television. How【 52】 of these drivers realize that it takes a car about one hundred metres to bra

28、ke to a stop【 53】 70 mph? Drivers also seem to think that motorway driving gives them complete protection from the changing weather.【 54】 wet the road, whatever the visibility in mist or fog, on they【 55】 at ridiculous speeds oblivious of police warnings or speed restrictions【 56】 their journey come

29、s to a conclusion. Perhaps one remedy【 57】 this motorway madness would be better driver education. At present, learner drivers are bared【 58】 motorways and are thus as far as this kind of driving is【 59】thrown in at the deep end. However, much more efficient policing is required,【 60】 it is the duty

30、 of the police not only to enforce the law but also to protect the general public from its own foolishness. （ A） for （ B） after （ C） to （ D） by （ A） more （ B） far （ C） less （ D） lesser （ A） another （ B） other （ C） one （ D） the other （ A） come up （ B） occur （ C） be found （ D） arise （ A） everywhere （

31、B） elsewhere （ C） anywhere （ D） somewhere （ A） pointed （ B） steep （ C） vertical （ D） sharp （ A） thus （ B） then （ C） so （ D） thereupon （ A） yet （ B） even （ C） still （ D） subsequently （ A） utterly （ B） simply （ C） barely （ D） purely （ A） because （ B） since （ C） when （ D） for （ A） too （ B） also （ C） un

32、duly （ D） unreasonably （ A） many （ B） much （ C） deeply （ D） profoundly （ A） to （ B） from （ C） at （ D） for （ A） Whatever （ B） However （ C） Whoever （ D） How （ A） push （ B） rake （ C） till （ D） plough （ A） unless （ B） before （ C） thus （ D） until （ A） to （ B） for （ C） of （ D） on （ A） from （ B） against （

34、struggle【 43】 as an upward movement is【 44】 toward ever more justice and opportunity. Technology in and of【 45】 is not at fault; its much too simple to say that gunpowder or agricultural machinery or fiber optics【 46】 been the enemy of an【 47】 group of people. A certain machine is put【 48】 work in a

35、 certain way-the purpose【 49】 which it was designed. The people who design the machines are not intent on unleashing chaos; they are usually trying to【 50】 a task more quickly, cleanly, or cheaply,【 51】 the imperative of innovation and efficiency that has ruled Western civilization【 52】 the Renaissa

36、nce. Mastery of technology is second only【 53】 money as the true measure of accomplishment in this country, and it is very likely that by【 54】 this under-representation in the technological realm, and by not questioning and examining the folkways that have【 55】 it, blacks are allowing【 56】 to be kep

37、t out of the mainstream once again. This time, however, they will be【 57】 from the greatest cash engine of the twenty-first century. Inner-city blacks in particular are in danger, and the beautiful suburbs【 58】 ring the decay of Hartford, shed the past and learn to exist without contemplating or enc

38、ountering the tragedy of the inner city. And blacks must change as well. Tile ways that【 59】 their ancestors through captivity and coming to freedom have begun to loose their utility. If blacks【 60】 to survive as full participants in this society, they have to understand what works now. （ A） like （

39、B） as （ C） for （ D） with （ A） charity （ B） clarity （ C） cohesion （ D） oppression （ A） charting （ B） charts （ C） charted （ D） to chart （ A） progressing （ B） progressed （ C） clutched （ D） clutching （ A） itself （ B） themselves （ C） ourselves （ D） himself （ A） have （ B） to have （ C） has （ D） to has （ A）

40、 entirely （ B） enter （ C） entire （ D） entrance （ A） for （ B） off （ C） on （ D） at （ A） for （ B） to （ C） with （ D） before （ A） envelop （ B） accomplish （ C） enveloping （ D） accomplishing （ A） followed （ B） follows （ C） to follow （ D） following （ A） since （ B） on （ C） in （ D） at （ A） before （ B） to （ C）

41、 with （ D） from （ A） to tolerate （ B） tolerate （ C） tolerated （ D） tolerating （ A） encountered （ B） encountering （ C） to encounter （ D） encounters （ A） them （ B） us （ C） themselves （ D） ourselves （ A） excluding （ B） included （ C） including （ D） excluded （ A） where （ B） that （ C） how （ D） what （ A） s

42、ervicing （ B） encircle （ C） encircling （ D） served （ A） is （ B） were （ C） am （ D） have 87 【 C1】 （ A） for （ B） than （ C） as （ D） that 87 Between 5,000 million and 4,000 million years ago the Earth was formed, By 3,000 million years ago life had arisen and we have fossils of microscopic bacteria-like

43、creatures to prove it. 【 66】 Nobody knows what happened, but theorists agree that the key was the spontaneous arising of self-replicating entities, i. e. something equivalent to “genes“ in the general sense. The atmosphere of the early Earth probably contained gases still abundant today on other pla

44、nets in the solar system. Chemists have experimentally reconstructed these ancient conditions in the laboratory. If plausible gases are mixed in a flask with water, and energy is added by an electric discharge (simulated lightning), organic sub-stances are spontaneously synthesized. These include th

45、e building blocks of RNA and DNA. It seems probable that something like this happened on the early Earth. Consequently, the sea would have become a “soup“ of prebiological organic compounds.【 67】 Today the most famous self-replicating molecule is DNA (deoxyribonucleic acid), but it is widely thought

46、 that DNA itself could not have been present at the origin of life because its replication is too dependent on support from specialized machinery, which could not have been available before evolution itself began. DNA has been described as a“ high-tech“ molecule which probably arose some time after

47、the origin of life itself. Perhaps the related molecule RNA, which still plays various vital roles in living cells, was the original self-replicating molecule. Or perhaps the primordial replicator was a different kind of molecule altogether.【 68】 Variants that were particularly good at replication w

48、ould automatically have come to predominate in the primeval soup. Varieties that did not replicate, or that did so inaccurately, would have become relatively less numerous. This led to ever-increasing efficiency among replicating molecules. As the competition between replicating molecules warmed up,

49、 success must have gone to the ones: hat happened to hit upon special tricks or devices for their own self-preservation and their own rapid replication. The rest of evolution may be regarded as a continuation of the natural selection of replicator molecules, now called genes, by virtue of their capacity to build for themselves efficient devices (cells and multicellular bodies) for their own preservation and reproduction.【 69】 Fos
