初中英語(yǔ)情態(tài)動(dòng)詞的用法歸納,情態(tài)動(dòng)詞用法有哪些

情態(tài)動(dòng)詞的常見用法：

1.can和could的用法

(1)can/could 表示“能力;許可;可能性”等。could 為 can 的過(guò)去式。如：Can I use your book?我可以用你的書嗎?

(2)can 用在疑問(wèn)句中，表示征求意見、請(qǐng)求許可，答語(yǔ)仍用 can; could 用在疑問(wèn)句中，比can 更委婉、客氣，是一種禮貌的說(shuō)法，并不表示過(guò)去時(shí)態(tài)，答語(yǔ)用can，而不能用could。

Eg: -Could you tell me the way to the park?你能告訴我去公園的路嗎?

-Sorry. I can't. I'm new here。不好意思，我不知道。我是新來(lái)的。

[注意]

①can 和could 只能用于現(xiàn)在時(shí)和過(guò)去時(shí)兩種時(shí)態(tài)。

②另外， can't 可表示否定推測(cè)。

2.may和might的用法

may/might 意為“可以”，表示同意、許可或請(qǐng)求對(duì)方許可，也可表示祝愿。

might 是may 的過(guò)去式，有兩種用法：一種表示過(guò)去式;一種表示虛擬語(yǔ)氣，使語(yǔ)氣更加委婉、客氣，或表示可能性更小。

以may開頭的一般疑問(wèn)句，其否定回答用mustn't。

Eg: MayI use your book? 我可以用你用的書嗎?

He might be alive. 他可能還活著。

【注意】

can和may都可以用來(lái)表示請(qǐng)求或允許，但may比can更正式，更客氣。

3.must和should

(1)must意為“必須，應(yīng)當(dāng)”，含有一種命令的語(yǔ)氣，比較生硬，不容商量。否定形式mustn't, 表示“不得”，“一定不要”。如：

Eg:You mustn't drive after drinking。你絕不能酒后駕車。

①must 與 have to 的區(qū)別： must 表示說(shuō)話人的主觀意愿;have to 表示客觀需要。

②回答由must 引導(dǎo)的疑問(wèn)句:

肯定回答：Yes, …must.　如：

-Must I go home now?

-Yes, you must.

否定回答：No，…needn't./No，…don't/doesn't have to.

Eg：-Must I go home now?

-No, you needn't. 。

③must 表示對(duì)事物的推測(cè)，意為“想必;一定”，只用于肯定句中;表“推測(cè)”時(shí)，情態(tài)動(dòng)詞與動(dòng)詞原形，(常為be動(dòng)詞)連用，

如：The man must be your teacher。那個(gè)人一定是你的老師。

(2)should意為“應(yīng)當(dāng)，應(yīng)該”，表示建議或勸告，語(yǔ)氣比較委婉，客氣。否定形式為shouldn’t。

Eg: You should get up early.

You shouldn't eat too much sugar.

4.will和would

1）用于疑問(wèn)句，表示說(shuō)話人向?qū)Ψ教岢稣?qǐng)求或詢問(wèn)，用would比will更委婉，更客氣。

如：Will you please open the window？

Would you like some coffee?

2） would表示建議“你愿意…嗎”

-Would you like to go shopping with me?

-Yes, I’d love to. /I’d love to. But I’m busy now.

[注意區(qū)別]

①I’d like+n. … 我想要…(接名詞)

如：I’d like some water.

②I’d like to + v. … 我想要做…(接動(dòng)詞原形)

如：I’d like to go with Tom.

5、shall用于第一人稱 (I, we), 可以表示“將”和表示建議 “……好嗎?”

eg： ①Where shall we have dinner?

②-Shall we go fishing? -

- All right. \OK. \Good idea.
