28、 be too much for them.可知,此处指昨天不应该给这些花浇水。故选B。【点睛】情态动词+ have done结构:1.“must + have + 过去分词”表示对过去发生的事情或状态进行推测,语气比较坚定,通常只用于肯定句。如:It must have rained last night, for the ground is wet.2.“can / could + have + 过去分词”表示对过去某种情况的怀疑或不确定。can和could一般用于否定句和疑问句,could的语气较can弱。如:He cant have finished the work so soon.

29、3.“may / might + have + 过去分词”表示对已发生的动作或存在的状态进行不肯定的推测,might的语气比may弱一点.这种结构主要用于肯定句和否定句,疑问句改用can或could,如:They may not have known it beforehand.4.“need + have + 过去分词”表示过去做了不必做或不需要做的事情,或过去做某事纯属多余,如:I neednt have bought so much wineonly five people came.5.“should / ought to + have + 过去分词”表示过去本该做某事但没做,其否定式

Its the favorite wish I _.Ashould have waited forBmust have waited forCmay have waited forDcould have waited for【答案】D【解析】【详解】考查情态动词+have done形式。 句意:爷爷祝您长寿!谢谢,这是我能够等待到的最喜欢的愿望。A. should have waited for 本应该等待; B. must have waited for 一定在等待;C. may h

33、ave waited for可能已经等待; D. could have waited for可以已经等待的。表示可以等到的愿望用could have waited for。故选D。【点睛】情态动词have done不仅是高中英语教学的重点和难点,也是高考的重点。情态动词have done有两大功能:一是表示推测;二是表示虚拟。must have done过去一定做了某事,根据must的本意即可推敲出意思,比较好理解。The lights were out. They must have been asleep. 灯灭了,他们应该睡觉了。should have done本该做某事却没做,shou

34、ld是应该,重点记忆最后的结果是没做某事。You should have told her that you loved her.你本应该告诉她你爱她。could have done字面意思是可能已经做了某事,也可用作本能做却没做某事,重点记忆最后的结果是没做。You could have reviewed, but you played games all night.你本可以复习的,但你一晚上都在玩游戏。may have done也许已经做了某事。26If you wish, you _ come in and have a cup of tea with us any time.Awou

So you mean you will have to apologize to him?Amust findBmight findCshould have foundDmust have fo

36、und【答案】D【解析】【详解】考查must have done结构。句意:吉姆一定觉得我说的话很让人烦,尽管他什么也没说。所以你是说你得向他道歉?根据“though he didnt say anything.”可知此处表示对过去事情的肯定推测,用must have done表示“过去一定做了”,故D项正确。28(2018北京) In todays information age, the loss of data _ cause serious problems for a company.Aneed BshouldCcan Dmust【答案】C【解析】考查情态动词。句意:在今天的信息时代

37、,数据的丢失有时会对一个公司造成严重的问题。数据丢失造成严重问题是客观上会发生的情况,即“客观可能性”,故该空应用情态动词can。C选项正确。其余情态动词均没有该用法。need需要;should应该,竟然;must必须,肯定。点睛:can的基本用法:1. (表示能力、功能)能,会;2. (表示推测)可能,可能会;3.(表示允许,请求)可以;4.(表示客观可能性)有时会。29(2018天津) I cant find my purse. I_ it in the supermarket yesterday, but Im not sure.Ashould leaveBmust have leftC

38、might leaveDcould have left【答案】D【解析】【详解】考查情态动词表推测。句意:我不能找到我的钱包了,昨天我有可能把它落到超市了,但我不确定。根据句中时间状语yesterday可知,是对过去事情的推测,故用情态动词+ have done,再根据后句but Im not sure.可知,此推测为不能肯定的推测,故用情态动词could,表示“可能”。故选D。【点睛】情态动词是每年高考的热点也是难点。本题抓住两点:第一、时态。根据句中时间状语可以判断出是对过去事情的推测,故用情态动词 + have done;如果是对现在事情的推测,才用情态动词+v原形。第二、情态动词的选择

39、。must为肯定推测,表示“一定”,could为不肯定推测,表示“可能”,这样就能选出正确答案。30- Difficulties always go with me!- Cheer up! If God closes door in front of you, there be a window opened for you.AmustBwouldCcouldDcan【答案】A【解析】【详解】考查情态动词辨析。句意:困难总是伴随着我!高兴点! 如果上帝在你面前关上了门,一定有一扇窗户为你打开。A. must必须;B. would将要;C. could能,会;D. can能,会。must表示对现在的状态推测时,意为“一定”,表示可能性很大的推测。符合语境。故选A。【点睛】1) must用在肯定句中表示较有把握的推测,意为一定。2) must表对现在的状态或现在正发生的事情的推测时, must 后面通常接系动词be 的原形或行为动词的进行式。 3) must 表示对已发生的事情的推测时,must 要接完成式。4) must表示对过去某时正发生的事情的推测,must 后面要接完成进行式。5) 否定推测用cant。本句中的。must表示对现在的状态推测时,意为一定,表示可能性很大的推测。符合第2点用法。
