英语情态动词讲解及练习（附答案）情态动词讲解定义：情态动词表示说话人对动作的态度，比如：需要，可能，意愿，猜测或者怀疑等等。
情态动词本身有一定意思，但不完全，不能单独作谓语，必须与动词原形连用。
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。
②否定回答中，表示对他人造成一定伤害或影响，或表示违反了某种规定或法律时，用mustn’t较好。
e.g. ——Could I take the book out of the library? ——Sorry, you mustn’t.——May I smoke here? ——I’m afraid you mustn’t.③表示过去能力时，could 提问，只能用could回答。
e.g. ——Could you ride a bike when you were 4 years old? ——No, I couldn’t.(3)表提出意见或请求Can/Could you (please) do sth? = Would you (please) do sth? （此句型中some 不变any）e.g. Could you please give me a hand?Would you please pass me some salt?(4) 表示允许或承诺=maye.g. OK. You can /may come and find me at any time tomorrow.(5) 表示有一定把握的推测，用于否定句和疑问句。

e.g. He may have a lot of work to do. = Maybe he has a lot of work to do.You may be right. = Maybe you are right.(2) 表示请求“我可以……吗？”表示许可“你可以……” e.g. You may /can go now.——May I use your pen?——Yes, you may. / Yes, please. / Go ahead.——No, you can’t. / mustn’t.三、must 表示“必须，肯定，一定”，否定形式mustn’t = must not(1) 表示必须，意思同have toe.g. ——Must I do it now?——Yes, you must.——No, you don’t have to. / No, you needn’t.

e.g. I must study hard.It’s too late. I have to go now.②must 没有人称和时态的变化，而have to有。
e.g. He had to walk back home because he lost all his money.Mom will be away for a week, so we will have to do thecooking by ourselves.(2) 表示有把握的肯定句中的推测，“肯定，一定”，见“一、（5）”四、need 表示“需要”，否定形式needn’t = need not(1)作情态动词，仅用于否定句和疑问句。
