情态动词

情态动词是一种本身有一定的词义,表示说话人的情绪、态度或语气的动词,

没有人称和数的变化。情态动词不能单独作谓语, 只能和其他动词原形构成谓语。具体说来:

(1) can/could/be able to

① can 表示能力,意思是“能”“会”

I can speak a little Chinese. 我能说一点汉语。

②表示客观可能性或推测,用于否定句或疑问句。

He can’t be a teacher.他不可能是位老师。

③表示非正式的请求或许可,可和may互换,但may用于正式的请求或许可。

Can (May) I borrow your bike? 我能借你的自行车吗?

You can(may) go now. 你现在可以走了。

④can仅用于现在时或过去式(过去式为could),若用在其他时态必用be able to.

He will be able to answer the question. 他将能回答这个问题。

⑤could 也表示能够,跟can的用法相似,只不过比can的语气要弱。

(2)may/might

①表示正式的请求或许可,意为“可以”

May I come in? 我可以进来吗?

回答用:Yes, you may./ No,you can’t.(mustn;t).

② mustn’t做may 的否定回答,表示禁止不许。

③ might 也表示也许,跟may的用法相似,只不过比may的语气要弱。

(3)must/have to

①must“必须”,否定mustn’t时意为“禁止”。

②must表示推测,一般用在肯定句中,其可能性比may 大。

he must be a teacher.他肯定是位老师。

③回答:肯定回答用must,否定回答用needn’t.

---Must I finish it now? ---我必须现在完成它吗?

---Yes, you must ./No, you needn’t. /you don’t have to. ---是的,你必须。/不, 你不必。

④ have to表示客观的需要,must表示说话人主观看法。

My brother is very ill, so I have to send him to the hospital. 我弟弟病的很重,所以我得送他去医院。 We must work hard. 我们必须努力工作。

⑤ must 没有人称和数的变化,但have to 有人称和数的变化。

He must go now. 他必须现在就走。

He has to stay at home. 他不得不待在家。

(4)need

1

①表示“需要” He need food.

②注意:区别need做情态动词和实意动词。

做情态动词:need+动词原形,need没有时态和数的变化 She need money. She needn’t clean the room. 做实义动词:need+to do/ doing/ to be done

人+need +to do 例如:We need to drink water.

人/物+need +doing ,表示被动意义或者说是用主动代替被动 。例如:The old man needs

looking after。 The bed needs cleaning.

人/物+need +to be done 直接用被动 试比较:The old man needs looking after.= The old

man needs to be looked after. The sofa needs cleaning.= The sofa needs to be cleaned.

(5)shall/should/ought to表示应该。

① shall用于第一、第三人称疑问句中,表示说话人征求对方的意见或请求。

Shall Tom go there with me tomorrow? 汤姆明天可以和我们一起去吗?

② should 和ought to表示义务,职责,按道理说应该。。。

We should/ought to study for our country. 我们应当为我们的国家努力学习。

注意:should多表达自己的主观看法,ought to 则多反映客观情况,在谈到法律、义务和规定时使用。 ③ ought to do 的否定形式是 ought not to do

Humans ought not to pollute the nature. 人类不应该污染自然。

(6)will/would表示意愿。

①will可以表示意愿、意图和决心,意为“要,愿”。

I will do my best. 我将尽我的最大努力。

②would表示主观意愿或意志,用于第二人称的疑问句时,表示谦恭的请求或征求意见,比will更可气。 He would like a cup of tea. 他想要杯茶。 Would you mind my opening the door?你介意我打开门吗?

(7)had better

①表示最好。。。,后接动词原形。 You’d better put on your cold. 你最好穿上你的外套。

②它的否定形式是在better后加not. You’d better not smoke.你最好不要抽烟。
