情态动词用法及练习题一、情态动词的概念:情态动词主要用以表明说话者对某一行为的态度和观点,主要包括揣测、判断、需要及各种意愿。
常见的情态动词有can、may、could、must、have to、should、would等。
二、情态动词的特征(1)情态动词本身有词义,但词义不完整,因此不能独立作谓语,只能和主要动词一起构成谓语。

例如:I/She can sing.(4)它的否定式一般是在其后加 not构成,在一般疑问句中通常将其提到句首。
结构如下:①肯定句:主语+情态动词+动词原形+其他。
例如:He can swim.②否定句:主语+情态动词+not+动词原形+其他。
例如:He can't swim.③一般疑问句:情态动词+主语+动词原形+其他?Yes,主语+情态动词. No,主语+情态动词+not.例如:-Can he swim?-Yes, he can. No,he can’t.④特殊疑问句:特殊疑问词+情态动词+主语+动词原形+其他? 例如: -What can he do ?-He can swim.三.情态动词的用法(1)can的用法①表示“能力”Can you sing?你会唱歌吗?②表示客观条件允许You can listen to music here.你可以在这里听音乐。
You can’t park your car here. 你不能在此停车③can用在否定句和疑问句中时,有时表示说话人的怀疑、惊异、或猜测:It can’t be true.这不可能是事实Can it be true?这可能是真的吗?④.can的搭配用法:A.as +adj./adv.+as one can/could “尽可能,尽量……”,如:The man took his child to the hospital as quickly as he could.这个男人尽可能快地将孩子送去医院。

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。
