有实际词义,但是没有单复数等词形变化。

后面通常加动词原形中考主要考查can,must,may,need四个情态动词。

除此之外,表示必要性的情态动词还有should,应该,这个语气比must弱,还有易考点:一.比较have to和must:1) 两词都是'必须'的意思,have to表示客观的需要,must 表示说话人主观上的看法,既主观上的必要。

My brother was very ill, so I had to call the doctor in the middle of the night.我弟弟病得很厉害,我只得半夜里把医生请来。

(主观上要做这件事)2) 在否定结构中:don't have to 表示"不必" mustn't表示"禁止",You don't have to tell him about it. 你不一定要把此事告诉他。

You mustn't tell him about it. 你一定不要把这件事告诉他。

二.肯定句中,表示推测,语气最强的是must,但在否定句和疑问句中,表示怀疑,猜测,要用can’t. (mustn’t禁止,不允许,不能用来表推测;can’t 不可能)There is someone knocking the door. It must be Tom.It can’t be Tom in the classroom. Because he is ill and he doesn’t come to school today.三.情态动词的回答1. 以can开头的一般疑问句,其肯定和否定回答分别用:can和can’t。

英语情态动词讲解及练习(附答案)

情态动词讲解定义:情态动词表示说话人对动作的态度,比如:需要,可能,意愿,猜测或者怀疑等等。

情态动词本身有一定意思,但不完全,不能单独作谓语,必须与动词原形连用。

否定句中,在情态动词后面加not。

情态动词有:must, shall, should, had better 词形无变化can(could), may(might), will(would) 词形有变化need既可以是情态动词,也可以是实义动词,具有双重性。

一、can 表示“能,会”,否定为:can’t = can not = cannot其过去式为:could→couldn’t(1)表示会做某事,有能力做某事。

意思= be able toe.g. He can speak English, but he can’t speak Japanese.= He is able to speak English, but he isn’t able to speak Japanese.I could smile but I couldn’t speak w hen I was 2 months old.= I was able to smile but I wans’t able to speak when I was 2 months old.区别:① can只用于现在时和过去时(could), be able to 可用于各种时态。

e.g. They will be able to tell you the news soon.Mingming has been able to count numbers.② be able to 不与can连用,但可以和其他情态动词或助动词连用。

e.g. He may be able to speak English very well some day in the future.He may can speak…………………………………………………..He can be able to speak……………………………………………..(2)用于征求意见——Can /Could /May /Might I(we) do sth?——Yes, you can/may. / Of course you can.——No(Sorry), you can’t. /mustn’t.注意:①此处的could和might都不表示过去,只是语气上的委婉,不用作回答。
