Y ou must have sat up late last night. 你看上去这么困倦, 昨晚一定睡得很晚。 I mailed that letter a week ago.

Must 加动词原形的进行式, 表示对现在发生动作和事物的猜测, 有“一定, 准是”的意思。 其它情态动词如may (might), should (ought to), can(could), need的用法分别如下: 二、may(might) may(might) + have + -ed 分词: 用于肯定句和其它否定句, 表示对已发生事情的不肯定的推测, 意为“可能, 大概”, 其中might较may语气更弱, 把握更小。 They may have derived inspiration from these words. 他们可能从这些话语中获得了灵感。 Our manager may (might) have gone to Guangzhuo attending Spring Fair there last week. 我们经理可能已于上周去广州参加春交会了。

初中英语情态动词用法归纳

He is on a visit to the GreatlW不可能。咱们老师正在游览长城呢。 【例题】一I think Miss Gao must be in the library. She said she would go ther—No. She __be there, I have just been there. A.can ' t B.mustn ' t C.needn ' t D.wouldn 't 【解析】根据下文我刚去过那儿”可知,应为不可能” can'表示推测[答案]A 2. could 的用法: (1).can的过去式,意为能、会”表示过去的能力。女口:He could write poems when he was 10. 他十岁时就会写诗。 (2). could在疑问句中,表示委婉的语气,此时could没有过去式的意思。如:Could you do me a favour?你能帮我个忙吗?一Could I use your pen?我能用一下你的钢笔吗?一Yes, you can可以。(注意回答) 3. may 的用法: (1) .表示请求、许可,比can正式,如:May I borrow your bike?我可以借你的自行车吗?You may go home now现在你可以回家了。 【例题】一______ I borrow your MP3?- Sure . Here you are. A. May B.Should C.Must D. Would 【解析】在此处表示请求,意为做……可以吗”答案:A (2) .表示推测,谈论可能性,意为“可能,或许”,一般用于肯定句中。如:It may rain tomorrow .

would的用法

will, be going to 和would的用法区别 will, be going to 和would都有将要或将会干什么的意思,但是在用法上有很大的区别。 will 通常表示确定或计划好了的将来会/要发生的事,一般不以个人的主观意志为转移,或者主观上决定了不再改变的事。比如:I will be 30 next month(不是我啊). It will rain tomorrow (根据气象台的报道). I will donate $1000 to my alma mater(也不是我啊)。 be going to通常表示即将要做或发生的事,主观愿望或判断很强烈,中文里相当于“打算”。美语口语常说成gonna. I am going to play soccer this afternoon. It's gonna be raining (我的判断). I am not gonna buy that car right now, but I'll do it after I get a job. (感受一下going to 和 will的差别) 两者的区别还在于,will 较 be going to 更书面化一些,be going to更口语化,通常说成gonna, 但说be going to也很正常,不过,如果你说英语不是那么地道就不要说gonna,否则人家反而觉得别扭。好比一个普通话都说不清楚的南方人,到了北京,本来人家也不会笑话你什么,不过你什么都没学会就,“边儿去”倒说得挺标准,还老用个没完,那听了可就有点儿别扭了。另外,有时候will 和be going to 的区别 也不明显,两者常可以互换使用,初学者不用太为计较。 至于 would,很有讲头啊。它原来是will的过去式。所以它的第一功能是表示过去将会发生的事。 比如: He told me he would not eat my mom's pancake. The baby was born to a poor farmer's family. Nobody knew he would become the 21th president o f United States of America 40 years later. (这是我随口瞎编的啊) The driver would have been in trouble if he'd drunk that night. would的第二层用法是最常见的和like或love联用,表示很想或很愿意做一件事,love则比like更为强烈。有些朋友想学一些最基本实用有趣的东西,这里我就引用一个美国朋友给我发的email中的一段,他恰好like和love都用了。We would like you to join our family for a traditional Christmas dinner on 25 December. We woul d love to have you come to Estes Park and enjoy a meal at our table and see some of our winter beauty. would的第三层用法在于,表示客气,猜测或不确定等软化的语气。我们知道,英文里很多情愿动词 都有这个用法,比如may-might, can-could (将另文介绍)。 客气:Your assistance would be highly appreciated. Would you give me a hand? Would you shut up? 猜测或不确定:Jim would not stay there for a long time. 如果这里用will或is going to 来取代,则表示说话的人有足够的理由或证据做这个判断,Jim计划中不会呆太久,或他这次没打算呆太久。用would只表示一种猜测,基于对Jim这个人一贯做法的了解,而不是瞎猜的。言下之意就是说,(以Jim这个人 的一贯做法),他是不会在那儿呆太长时间的。 由此引出would的第四种用法,表示一种倾向和一贯做法。比如:I would say I don't like Bush's administration. 这里省略的潜台词是,(如果你一定要我下一个
