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。

咱们老师正在游览长城呢。

【例题】—I think Miss Gao must be in the library. She said she would go there.—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’t表示推测[答案] A2. could的用法:(1).can的过去式,意为“能、会”,表示过去的能力。
