初中情态动词简明用法及练习

▲can cannot = can’t

1. 表示能力,意为“能、会”。≈ be able to can’t 意为“不能”

如: A:Can you sing ? B:Yes,I can. No,I can’t.

2. “可以”, 没有could 委婉, 没有may正式 。 can’t 意为“不可以”

用can’t还可表示推测,“不可能”、 “不一定”,

表示说话人心里有十足的把握。

▲could

1.can的过去式

2. “可以”(常用在一般现在时的一般疑问句中),比 can 委婉, 没有may正式。 回答一律用 can

或can’t

如: A: Could I open the window? B: Yes, you can . 或 No, you can’t.

▲ must

1.“应该、必须”, 强调说话人的主观看法,常含有命令、被命令的意味。

A: Must he go ? B: No, he / 或 Yes, he must .

2.表示推测, “一定”

*mustn’t 表示“禁止”,意思是“不应该、不必、不许”。 (不表示“不一定”)

▲ may

1 “可以”,比can正式。 may not 译成“不可以”

如: A: May I stay at home? B: No, you 或 Yes, you may.

2 表示推测, “可能” may not ,表示说话人心里没多

大把握。

▲ should ≈ ought to的用法: “应该”,大多数情况下可以互换。表示规劝。should的否定式为

shouldn’t ; ought to的否定式为oughtn’t to

A: Ought I to stop smoking ? B: Yes,you ought to. / No, you oughtn’t to.

▲ will 将要 否定式:will not = won’t

▲ would

①. will的过去式

②. will更委婉的说法,常和like构成would like (想要)

▲need的用法

1.作为情态动词,need一般只用于否定句和疑问句中。

You needn’t try to explain.

Need she do it at once? Yes, she must. No, she needn't.

2.need 作为实意动词比作为情态动词常用的多。实意动词need 可用在所有句型中。

You don’t need any help from others. Do they need this?

need to do sth 需要去做sth 如:She needs to come tomorrow.

need doing sth ≈ need to be done sth 需要被do sth ,具有被动的意味, 如:The bike needs

repairing . ≈The bike needs to be repaired .
