I need them tomorrow afternoon.—They should be ready by 1200.七、情态动词表示推测1．can用于肯定句中表示客观的可能性,意为“有时会”；用于疑问句中可以表示推测,意为“可能”,有时表示一种惊讶的语气；用于否定句中也可以表示推测,can't意为“不可能”,语气很强烈.It is usually warm in my hometown in March, but it can be rather cold sometimes.我的家乡在三月份通常很暖和,但有时候也会相当冷.Mr. Bush is on time for everything. How can it be that he was late for the meeting?布什先生做什么事情都很准时,他怎么可能开会迟到呢？—Let's visit Tom together, Stephen.—There's no need to do so. He can't be at home, because I saw him board the flight to Beijing this morning.——Stephen,咱们一起拜访汤姆吧.——没必要这样做.他一定不在家,因为今天早晨我看见他登上了飞往北京的航班.2．may/might用于肯定句中可以用来表示不十分肯定的推测,意为“有可能”；用于否定句中也可以表示推测,may not意为“可能不”,表示一种不太确定的语气.The traffic is heavy these days. I might arrive a bit late, so could you save me a place?这些天交通很繁忙,我可能会来晚一点,请你帮我保留个位置好吗？3．must表示推测时只能用于肯定句中,意为“一定,必定”,表示十分肯定的语气(在疑问句中或否定句中要用can/could).—It's the office! So you must know eating is not allowed here.—Oh, sorry.——这是办公室！所以你一定知道这里不许吃东西.——噢,对不起.4．should用来表示推测时意为“应该”,即含有“按道理来说应当如此”的意思.There shouldn't be any difficulty about passing the road test since you have practiced a lotin the driving school.因为你在驾校训练了这么多,通过路考应该没什么困难.八、“情态动词＋have done”结构1．should/ought to＋have done,表示“过去本应该做而(实际)没有做的事情”,含有责备或遗憾的语气,意为“本应该……”.其否定形式为“should not/ought not to have＋done”,表示某种行为本不该发生但实际上发生了.I shouldn't have watched that movie—it'll give me horrible dreams.我本不应该看那部电影——它会令我做噩梦.You ought to have come to the party yesterday, but why didn't you come?昨天你本来应该参加聚会的,可是你为什么不来？2．must＋have done,用于肯定句,表示“过去一定做过某事”,表示一种很有把握的推测.注意,对过去发生的情况的否定推测常用“can't/couldn't＋have done”表示.—Ye Shiwen won two gold medals in London Olympic Games.—She must have gone through tough training.——叶诗文在伦敦奥运会获得了两枚金牌.——她肯定受到严格的训练.—Do you know where David is? I couldn't find him anywhere.—Well. He can't have gone far—his coat's still here.——你知道大卫在哪里吗？我到处找不到他.——大卫的上衣还在这里,因此他肯定没走远.3．needn't＋have done,表示“过去没有必要做某事,但实际上做了某事”.Mark needn't have hurried. After driving at top speed, he arrived half an hour early.马克本没必要那么匆忙.他以最快速度开车,结果早到了半个小时.4．may/might＋have done,表示对过去情况的一种不太有把握的可能性的推测,表示“可能已做了某事……”,否定句表示“可能还没有……”.Sorry, I'm late. I might have turned off the alarm clock and gone back to sleep again.对不起,我迟到了.我可能把闹钟关掉后又睡着了.5．could＋have done表示“过去本来可以做某事,但实际上没有做”；can/could＋have done表示“过去可能做了某件事”.I could have saved the poor rabbit, but I didn't have the right drugs with me at that moment.我本来可以拯救那只可怜的兔子的,可是我当时没有合适的药品.第二部分、虚拟语气一、虚拟语气在虚拟条件句中的用法1.在具体运用中,条件从句中有时可省略if而采用倒装结构.如：Had it not been for your help, we wouldn't have achieved so much.2．介词without/but for、连词but、副词otherwise常用来表示某种假设条件.如：I wouldn't have made such rapid progress without your help.3．有时候从句动作和主句动作发生的时间不一致,这时谓语动词的形式要根据各自的时间来调整.如：If the weather had been more favourable, the crops would be growing still better.二、“should＋动词原形”表示的虚拟语气这一类型常见词有“一坚持(insist)、二命令(order, command)、三建议(advise, suggest, propose)、四要求(request, require, demand, desire)”.以上词及其派生名词所接的名词性从句都使用“(should ＋)动词原形”的虚拟语气.①Jane's pale face suggested that she was ill, and her mother suggested that she(should) havea medical examination.简苍白的脸色表明她病了,她母亲建议她去检查身体.②She insisted that the man had stolen her car and that he(should) be sent to prison.她坚持说那个男人偷了她的车,并坚决要求他坐牢.三、特殊句式中的虚拟语气If only/It's (high) time (that)．..wish/would rather/as if等固定句式要求用相应的虚拟语气表达形式.①I wish I could fly.真希望我能飞.②I would rather you came tomorrow.我宁愿你明天来.③If only I had taken your advice!要是听从了你的建议该多好啊！高频考点一、考查情态动词例1．（2018·北京卷）In today’s information age, the loss of data _________ cause serious problems for a company.A. needB. shouldC. canD. must【答案】C【解析】考查情态动词.句意：在今天的信息时代,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.【变式探究】—Can’t you stay a little longer?—It’s getting late.
