初中英语语法之情态动词用法及练习题(含答案)

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。

如：He was able to go to the party yesterday evening in spite of the heavy rain.2) 表示请求和允许。

---- C an I go now? Yes, you can. / No, you can 此时可'与t. may 互换。

在疑问句中还可用could, might 代替，不是过去式，只是语气更委婉，不能用于肯定句和答语中。

初中英语情态动词讲解练习及答案

初中英语情态动词用法详解【情态动词知识梳理】情态动词有具体的词义，但也同助动词一样，需要与其他词语一起构成句子的谓语，另外情态动词没有人称和数的变化，情态动词后必须跟动词原形。

考点一：can，may，must等情态动词在陈述句中的用法：1. can的用法：〔1〕.表示能力、许可、可能性。

表示能力时一般译为“能、会〞，即有种能力，尤其是生来具备的能力，此时may和must均不可代替它。

如：She can swim fast, but I can’t . 她能游得很快，但我不能。

I can see with my eyes.我用眼睛看。

〔2〕.表示许可，常在口语中。

如：You can use my dictionary. 你可以用我的字典。

〔3〕.表示推测，意为“可能〞，常用于否认句和疑问句中，此时can’t译为“不可能〞。

如：Can the news be true?这个消息会是真的吗？—Can it be our teacher?那个人有可能是我们教师吗？—No, it can’t be our teacher. He is on a visit to the Great Wall.不可能。

咱们教师正在游览长城呢。

【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.【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]2. could的用法：〔1〕.can的过去式，意为“能、会〞，表示过去的能力。

如：He could write poems when he was 10. 他十岁时就会写诗。

〔2〕. could在疑问句中，表示委婉的语气，此时could没有过去式的意思。

如:Could you do me 你能帮我个忙吗？—Could I use your pen?我能用一下你的钢笔吗?—Yes, you can.可以。
