题目内容
9.At minus 130℃,a living cell can be ________ for one thousand years.( )A. | preserved | B. | protected | C. | spread | D. | developed |
分析 在零下130℃,一个活细胞可以保存一千年的时间.
解答 答案A.B项"保护";C项"传播,散布;展开;伸展;铺开";D项"发展,进步;使成长,冲洗(胶片)"A项"保存,保持,维持";根据句子结构分析及句意可知,这里考查含有情态动词的被动语态"be+动词的过去分词","被保存 sth be preserved",因此A项符合语境,故选A.
点评 本题考查动词的被动语态.被动语态表示句子的主语是动作的承受者,也就是动作的对象,一般说来只有及物动词才有被动语态.其构成为"be+及物动词的过去分词".助动词be有人称、数和时态的变化,其变化规则与be作为连系动词时完全一样.含有情态动词的谓语变化为被动语态时,由"情态动词(can,may must,have to等)+be+动词的-ed形式.

2.People select news in expectation of a reward.This reward may be either of two kinds.One isrelated to what Freud calls the Pleasure Principle,the other to what he calls the Reality Principle.For want of better names,we shall call these two classes immediate reward and delayed reward.In general,the kind of news which may be expected to give immediate reward are news of crime and corruption,accidents and disasters,sports,social events,and human interest.Delayed reward may be expected from news of public affairs,economic matters,social problems,science,education,and health.
News of the first kind pays its rewards at once.A reader can enjoy an indirect experiencewithout any of the dangers or stresses involved.He can tremble wildly at an axe-murder,shake hishead sympathetically and safely at a hurricane,identify himself with the winning team,laugh understandingly at a warm little story of children or dogs.News of the second kind,however,pays its rewards later.It sometimes requires the reader totolerate unpleasantness or annoyance-as,for example,when he reads of the threatening foreign situation,the mounting national debt,rising taxes,falling market,scarce housing,and cancer.It has a kind of"threat value."It is read so that the reader may be informed and prepared.When a reader selects delayed reward news,he pulls himself into the world of surrounding reality to which he can adapt himself only by hard work.When he selects news of the other kind,he usually withdraws from the world of threatening reality toward the dream world.
For any individual,of course,the boundaries of these two classes are not stable.For example,asociologist may read news of crime as a social problem,rather than for its immediate reward.Acoach may read a sports story for its threat value:he may have to play that team next week.Apolitician may read an account of his latest successful public meeting,not for its delayed reward,but very much as his wife reads an account of a party.In any given story of corruption or disaster,a thoughtful reader may receive not only the immediate reward of indirect experience,but also the delayed reward of information and preparedness.Therefore,while the division of categories holds in general,an individual's tendency may transfer any story from one kind of reading to another,ordivide the experience between the two kinds of reward.

Division of news stories | •People expect to get (71)rewards/rewardedfrom reading news. •News stories are roughly divided into two classes. •Some news will excite their readers instantly while others won't. |
(72)Explanationsof the two classes | •News of immediate reward will seemingly take their readers to the very frightening scene without actual (73)involvement. •Readers will associate themselves closely with what happens in the news stories and (74)sharesimilar feelings with those involved. |
•News of delayed reward will make readers suffer,or present a(75)threatto them. •News of delayed reward will induce the reader to (76)preparefor the reality while news of immediate reward will lead the reader to (77)withdraw from the reality. | |
Unstable boundaries of the two classes | What readers expect from news stories are largely shaped by their (78)profession(s)/intention. Serious readers will both get excited over what happens in some news stories and (79)adapt themselves to the reality. Thus,the division,on the whole,(80)dependson the reader. |
