Modal verbs 文法

Modal verb 中文是情感動詞,用來表達可能、意願、必要性等動詞。

我們從不會在情態動詞後面的動詞加上 -ing、-s 或 -ed。

我們也不需要使用助動詞 do 構成疑問句和否定句的動詞。

Modal verbs有哪些

Modal verbs 例子包括:

can, could, may, might, must, ought to, shall, should, will, would

Modal verbs 用法

Modal verbs 用法

Modal verbs 用法主要有5種:

  1. 談及能力
  2. 提出請求並請求許可
  3. 談及可能性和確定性
  4. 談論必要性和禁止
  5. 提供建議


modal verb examples

在談及能力時,我們會使用can could等 modal verbs。

類似be able to。

我們用 could 來談論過去的能力。在這些情況下,could 是 can 的簡單過去式

我們還用 could 來談論某人何時開始能夠做某事

用法一 can 例句

I can play tennis very well

I cannot (can’t) windsurf at all

Can you play tennis? Yes, I can.

Can you windsurf? No, I can’t。

用法一 could 例句

When he was young, my grandfather could run the 400-metre race faster than anyone else at his school.

(He could do it then, but he can’t do it now.)

I could swim when I was four.

(I learnt to swim when I was four. I can still swim.)


modal verb meaning

我們使用modal verbs can/could/may/might + bare infinitive來提出請求和請求許可。

不同modal verbs取決於情況的正式程度:


(最不formal) can could may might (最formal)

若果要提出要約和邀請,我們使用表達方式 would like

用法二 例句

Can you lend me your calculator?

Could you pass the salt?

May I go to the toilet, sir?

Excuse me, may I ask you a few questions?

Would you like a drink?

Yes, please.

Would you like to come to my party?

I’d love to.

用法二 常見錯誤

我們只在希望被允許做某事時才使用 may。不過,我們不能用 May you(或 Might you)提出請求:

(錯誤)May you give me a lift to the airport?

(正確) Could you give me a lift to the airport?



我們使用modal verbs may/might/could + bare infinitive來談論可能性,我們使用 will、shall 和 must 來談論確定性


will shall must

Less certain

may might could

用法三 例句

There must be some special event today.

It will take longer than usual to get to school today.

There’s very little traffic today. It won’t take long to get to school.

I shall be away for only a few days.

I shan’t be away for long.

We may have to go to a convenience store instead.

I’m not sure where the calculator is. It could be/might be in my bag.



我們用 must/have to/need to + bare infinitive 來談論必要性,即必須的事情/我們被要求或期望做的事情。



must have to need to

should ought to

我們使用否定形式 must not(不得)和 cannot(不能)來談論禁止,即不允許我們做的事情:

用法四 例句 (必要性)

All children must go to school.

I had to walk to school when I was a child.

I should go to the gym, but I’m too tired.

I really ought to go home, but I don’t want to miss the second half of the game.

用法四 例句 (禁止)

You mustn’t cross the street here.

We cannot wear jeans to school.

用法四 常見錯誤

否定式 must not vs need not 兩者的意思是很不同的:

You mustn’t go in there. It says ‘No entry’.


You needn’t go in there. There’s nothing in there.




我們可以使用 must/have to/need to/had better/should/ought to + bare infinitive來給出建議。

我們根據我們的建議的強弱程度使用不同的modal verbs:



must have to need to

should ought to

用法五 例句

You should/ought to take up a sport.


You should not (shouldn’t)/ought not to (oughtn’t to) watch so much TV.


Should I start playing football? Which team should I join?

要談論過去的動作,我們還使用結構:modal verbs + have + 過去分詞:

You should have come to the match.

You shouldn’t have stayed at home alone.

You needn’t have spent money on a ticket.

I could have given you one for free.
