初中情态动词知识点及习题(附答案)
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。

(完整)情态动词专题讲解
(完整)情态动词专题讲解情态助动词专题训练概说助动词（auxiliary)主要有两类：基本助动词(primary auxiliary）和情态助动词（modal auxiliary）。
基本助动词有三个：do， have和be；情态助动词有十三个：may, might; can, could; will, would； shall， should； must, need， dare， used to, ought to。
上述两类助动词的共同特征是，在协助主动词构成限定动词词组时，具有作用词的功能：1）构成否定式:He didn’t go and neither did she.The meeting might not start until 5 o'clock。
2) 构成疑问式或附加疑问式：Must you leave right now?You have been learning French for 5 years, haven’t you?3) 构成修辞倒装:Nowhere can he obtain any information about his sister。
Hardly had he arrived when she started complaining.4）代替限定动词词组：A: Who can solve this crossword puzzle？B： Tom can.A: Shall I write to him?B： Yes， do.情态助动词的特征基本助动词与情态助动词最主要的区别之一是，基本助动词本身没有词义,而情态助动词则有自己的词义，能表示说话人对有关动作或状态的看法,或表示主观设想：What have you been doing since？（构成完成进行体,本身无词义）I am afraid I must be going. （一定要）You may have read some account of the matter. (或许已经）除此之外，情态助动词还有如下词法和句法特征：1）除ought和used以外，其他情态动词后面只能接不带to的不定式。

否定句中，在情态动词后面加not。
情态动词有：must, shall, should, had better 词形无变化can(could), may(might), will(would) 词形有变化need既可以是情态动词，也可以是实义动词，具有双重性。
一、can 表示“能，会”，否定为：can’t = can not = cannot其过去式为：could→couldn’t(1)表示会做某事，有能力做某事。
意思= be able toe.g. He can speak English, but he can’t speak Japanese.= He is able to speak English, but he isn’t able to speak Japanese.I could smile but I couldn’t speak w hen I was 2 months old.= I was able to smile but I wans’t able to speak when I was 2 months old.区别：① can只用于现在时和过去时(could), be able to 可用于各种时态。
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。
