(易错题精选)初中英语语法知识—情态动词的图文答案

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。

初中情态动词讲解及练习题情态动词表示语气和态度。

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。

(客观上需要做这件事)He said that they must work hard.他说他们必须努力工作。

（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。
