情态动词

A、在前面的章节中，will专用来表示意图： I will wait for you．相当于： I intend to wait for you． 我会等你。 在不存在任何意图的场合用shall，即shall用于不牵涉到主语愿望的动作： I shall be 25 next week． 下星期我就25岁了。 We shall know the r...

它们都属于表示知觉的连系动词，意思分别是看起来、听起来、闻起来、尝起来、摸起来。使用时注意以下几点： (1) 通常以物作主语，表示人的知觉状态或感觉能力，虽有被动词味，但不用被动语态。如： 误：The stone is felt smooth. 这种石头摸上去很光滑。 正...

三者均属于表示状态的来连系动词，都有好像、似乎的意思，区别如下： (1) seem 侧重指事实上似乎是那样的；look 指视觉印象，指看起来似乎如此；appear 指从表面上看似乎如此，但有时并非如此。。如： They seemed tired and unhappy when they got home. 他...

1. 表示义务、命令或必要 主要用于用于肯定句、否定句和疑问句。具体用法如下： (1)意为必须。如： Soldiers must obey orders. 军人必须服从命令。 Something must be done to stop pollution. 必须采取措施来防止污染。（可跟被动语态） I think I must be...

情态动词有can (could), may (might), must, have to, shall (should, will (would), dare (dared), need (needed), ought to等。 情态动词无人称和数的变化；不能单独使用，必须与其后的动词原形构成谓语。 一、 can, could 1) 表示能力（体力、知识、技能...

含有情态动词的谓语变成被动语态时，结构为： 一般式：情态动词（can,could,may,might,must,should,need等）+be+过去分词 完成式：情态动词（can,could,may,might,must,should,need等）+have+been+过去分词 例句： Lost health may be replaced by temperanc...

(would可以看作是will的过去式,这两个词除了时态不相同外,在表达意思的许多方面是相近的。当然will 和would又都有一些各自不同的独特用法。) 1)用于第二人称疑问句,表示请求(在这种用法中would使语气更为客气、委婉) Will you tell her that I'll be back in...

1. 基本原则 在通常情况下，当陈述部分含有情态动词时，反意疑问句会重复前面同样的情态动词： The boy can read and write, can't he? 这男孩会读写，是吗？ We shouldn't help him, should we? 我们不应该帮助他，对吗？ You couldn't lend me any money,...

表示义务、意图或建议：必须，应该 I must leave at six today. 我今天必须六点钟离开。 I must write a letter to the head teacher. 我非得给校长写封信不可。(强烈意图) You must go and see that filmyou'd really enjoy it. 你得去看看那部电影，你会真...

这两词既可做实义动词用，又可做情态动词用。作为情态动词，两者都只能用于疑问句，否定句和条件句。 need 作实义动词时后面的不定式必须带to，而dare作实义动词用时, 后面的to 时常可以被省略。 1) 实义动词： need （需要, 要求） need + n. / to do sth 2...

带to 的情态动词有四个：ought to, have to, used to, be to, 如加上have got to ,(=must), be able to，为六个。它们的疑问，否定形式应予以注意： Do they have to pay their bill before the end of the month? She didn't use to play tennis before she...

问句 肯定回答 否定回答 Need you? Yes, I must. No,I needn't Must you? /don't have to. 典型例题 1）---Could I borrow your dictionary? ---Yes, of course, you____. A. might B. will C. can D. should 答案C.could表示委婉的语气，并不为时态。答语中...

注意： 1）would like； Would like to do = want to 想要，为固定搭配。 Would you like to go with me? 2）Will you? Would you like? 表示肯定含义的请求劝说时，疑问句中一般用some, 而不是any。 Would you like some cake? 3）否定结构中用will，一般不...

1) would rather的用法 would rather do would rather not do would rather than 宁愿而不愿。 还有would sooner, had rather, had sooner都表示宁愿、宁可的意思。 例句： If I have a choice, I had sooner not continue my studies at this school. I wou...

1) had better 相当于一个助动词，它只有一种形式，它后面要跟动词原形。 had better do sth had better not do sth It is pretty cold. You'd better put on my coat. She'd better not play with the dog. 2) had better have done sth表示与事实相反的结...
