初中英语语法知识—情态动词的综合训练

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 can play the piano.（ can play整体为谓语）(2)其后动词使用原形。

例如：You should lie down.(3)情态动词一般没有人称和数的变化(即不管是何人称，后面接的情态动词都不变)。

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。
