情态动词归纳及专项练习题
情态动词归纳及专项练习题 一、单项选择情态动词 1．If we had paid enough attention to the issue of the heavily-overloaded vehicles, the tragedy of the collapse of an overpass in Wuxi _____ avoided. A．should B．could be C．should have been D．could have been 【答案】D 【解析】 【详解】 考查情态动词用法。句意：如果我们对超载车辆问题给予足够的重视，就可以避免无锡立交桥垮塌的悲剧。本句为“情态动词+have done”结构，结合句意表示“本来可以；本来能够”应用could have done结构，且主语与谓语动词avoid构成被动关系，故应用be done形式。故选D。 【点睛】 情态动词+have done的结构和用法有以下几种： 一、must have done sth.“一定做了某事”。表示对过去事情的较有把握的推测，这时只能用在肯定句中，“肯定/必须已经干过……”，在否定句和疑问句中用can’t或co uldn’t或can/ could，例如： 1.From what you said, she must have told you all about it. 从你的话看，她一定告诉了你所有的事情。 二、can/could have done sth.本来能够做某事，而实际上未做； 1.But we could have done it all so much better. 但是，我们本可以把这一切做得更好。 三、can't/couldn't have done sth.不可能做过某事； 1. We could't have done it without you. 没有你我们办不成这事。 四、ought to/should have done sth.过去本应该做某事而实际上并没有做。 You should have done it when you first saw them blooming this spring. 你应该在今年春天第一次看到它们盛开的时候就挖一些的。 2.Even if it’s something you should have done earlier in the wee k or missed a detail on. 甚至你在一个星期前的就提早完成了一件事或者忽略了一个小细节。 2．—I don’t really like Janes. Why did you invite him? —Don’t worry. He come. He said he was’t certain what his plans were. A．must not B．need not C．would not D．might not 【答案】D 【解析】 考察情态动词，题干中的he wasn’t certain说明他可能不来，可能来，因此使用不完全否定，might not。 3．--- Oh, my God! I just missed the last bus back home.

He asked whether he could take the book out of the reading-room. 4）表示对现在动作或状态的猜测，主要用于否定句和疑问句中或感叹句中: He can’t (couldn’t) be over sixty.他不可能超过六十岁。 5）could表示比can更委婉客气的提出问题或陈述看法，指的是现在时间。 Can (Could) you lend me a hand? 帮我一把好吗？ 2. may (might) 1）表允许，询问或说明一件事可不可以做，might指过去时间；但在疑问句中might也可指现在时间，语气比may更委婉。 May (Might) I ask for a photo of your baby? 我可以要一张你宝宝的照片吗？ 在回答以may引起的问句时，肯定回答是一般可仍用may,或Yes, please. / Certainly./Sure./Of course. ； 否定回答根据说话人的语气由强到弱分别选用: must not(mustn’t)（禁止）/ had better not（最好别）/ may not（不行） 2) may表可能,但所表示的可能性不如can所表示的那样肯定。might可以指过去时间，也可以指现在时间，但语气更加不肯定。 He may be at home. 他可能在家。 They might be having a meeting, but I’m not sure.他们有可能在开会，不过我不肯定。 3. must（have to表示客观需要） 1）表示“必须”（主观看法）时，用于肯定句或疑问句；用于否定句时表示“禁止”。 We must do everything step by step. 我们一切都必须循序渐进地做。 You must get home before 9:00. 2）表示揣测。意为“想必、准是、一定”等，只用于肯定句。 He must be ill.
