情态动词主要有： may/might, can/could,

must, have to, shall/should, will/would,

ought to, need, dare, used to 。

Grammar focus

现在我们来着重学习情态动词 can 以及have to 的用法。其特征主要有：

1. 不能独立作谓语，只能和动词原形一起构成谓语，表示说话人

的语气和情态。

2. 没有人称和数的变化。 (have to 除外 )

3. 否定形式：在其之后加 not (have to 除外 ) 。

　疑问形式：情态动词提到主语之前 (have to 除外 ) 。

can 为情态动词 , 在本单元中表示请求 ,

用于发出邀请，后跟动词原形。当同意接

受对方的邀请时 , 常用 Sure, I’d love to. /

Certainly. /Of course. 等来回答；若不接受 ,

常用 Sorry 等来有礼貌地拒绝 , 一般情况下

需要说明不能接受邀请的原因以表示歉意。

—Can you come to my birthday party tomorrow ？ 明天你来参加我的生日聚会，好吗？ —Sorry, I can’t. I am going to visit my grandpa.

很抱歉，我来不了，我要去看我爷爷。

1. can/may

(1)都可表示“许可” 。 may 用于较正式、客气的场合，而 can 比较随便（口语）。

You may/can smoke here.

Borrowers may not take out of the

library more than two books at a time.

The policeman says you can’t park here.

(2) May/Can I/we…? 表示征询对方许可。

Can you…? 表示请求。

— ① May I use your phone?

— Yes, you may./Yes, please.

/No, you may not.

　　 /No, you mustn’t.

/No, you’d better not.

/I’m afraid not.

/I’m sorry. I’d rather you didn’t.

②— Can I go out and play, Mum?

—Yes/Certainly, you can. /No, you can’t.

— ③ Can you help me with this bag?

—With pleasure./Sorry, I can’t.

(3) 都可表示“可能性”

　肯定句

　

Mr. Reed looks pale. He may be ill.

( 事实上的可能 ).

Mr. Read is in poor health. He can be ill at any time. ( 逻辑、理论上的可能 )

This news may be true. (=might/could)

( 事实上的可能 )

Wang Wei can be really stubborn.

( 有时或偶然可能会 )(=could)

否定句

This news may not be true.

( 也许不 , =might not )

This news can’t be true.

( 不可能 , =couldn’t)

疑问句

Can this news be true?(=Could)

≠May this news be true?

(4) can 还可表示“能力”、“能够”

—You can swim, can’t you?

—No, I can’t.

I can’t promise anything, but I’ll do what I can.

Tickets can be bought from the Tourist Information Center.

2. might/could

(1)分别为 may 和 can 的一般过去时，分别表示过去的“许可”、“可能”和“能力” 、“能够”等。

　 The children asked whether they could/might go for a swim.( 过去许可 )

I was afraid it might rain that afternoon.

( 过去可能 )

He asked if the news could be true.

( 过去可能 )(Can the news be true?)

She said he could speak several languages. ( 过去能力 )

I couldn’t find her telephone number.

( 过去能够 )

(2) 都可表示现在或将来的“可能性”。语气没有 may 肯定。

—① There’s someone at the door.

—It could/might(=may) be George. ( 肯定句 )

/It couldn’t (=can’t) be George.( 否定句 )

/Could(=Can) it be George?( 疑问句 )

② According to the radio it could/might/ may rain tomorrow.

③ Lightning could (=can) be dangerous.

(3) Might/Could I/we …?

Could you …?

表示更委婉、更客气的请求。

—① Might/Could I ask you one more question?

—Yes, of course you may/might/can/ could.

—② Could you help me with these boxes?

—Of course I can./With pleasure.

有时在陈述句中也表示更委婉、更客气的请求或邀请：

—I wonder if I could/might leave now.

—I don’t suppose you could/might.

3. can/be able to 　

(1)can= am/is/are able to

= shall/will be able to

① No one can do it.

=No one is able to do it.

② Can you come tonight?

=Will you be able to come tonight?

(2) could 表示过去的技能、本能 ; was/ were able to 表示过去某一具体场合经过努力而做成某事。

① I could swim when I was six.

② He started late, but he was able to catch the eight o’clock train.

=…but he managed to catch …

=…but he succeeded in catching …

But:

③Mr. Smith couldn’t/wasn’t able to see you because he’s got a bad cold.

(3) be able to 还有完成式和非谓语形式。 ① I’m sorry I haven’t been able to answer your letter.

=I’m sorry for not being able to answer your letter.

② To be able to run is very important for a footballer.

　　

4. have to 的意思是“必须、不得不” , 往往

强调由于客观原因而必须做某事。

have to 后接动词原形； have to 有人称、

数和时态的变化 , 其第三人称单数形式为

has to, 其疑问形式和否定形式要借助于

助动词 do 或 does 来完成。例如：

We have to look after our sister at home.

我们不得不在家照顾我们的妹妹。

Does he have to get up early tomorrow morning?

明天早上他必须早起吗？

I don’t have to stay at home today.

今天我不必呆在家里。

情态动词“ have to” 与其他的情态动词如“ can”, “may” “must” 和 “ should”

不同。1) 这 4 个情态动词没有人称的变化 ,

而 have to 有 , 它的第三人称单数 为“ has to” 如： He should study hard.

He has to study hard.

2) 这 4 个情态动词在一般疑问句中将它们放

在句首 , 在否定句中直接在他们后边加 not 即可。

我们以 can 为例 :

--Can he go with us? 他能和我们一起去吗？

--He can’t go with us. 他不能和我们一起去。

而“ have to” 要加助动词 do , does 或 did 才

可能完成其疑问句、否定句。

5. must/have to

(1)must 表示主观“必须”； have to 表示客观客观需要，即“不得不” 。

I don’t like this TV set. I must buy a new one.

This TV set doesn’t work. We have to buy a new one.

(now)

You must get up at five tomorrow.

We (will) have to get up early tomorrow —we’re going to

Devon. (future)

I had to leave early because I wasn’t feeling well.

She said she must/had to see the manager.

(past)

表示邀请的句型 : ( 你能来参加我的聚会吗 ?)

Can you come to my party?

Could you come to my party?

Would you like to come to my party?

接受邀请 :

拒绝邀请 :

Sure, I’d love/like to.

I’m sorry, I can’t. I have to…/I’m V-ing…
