情态动词表推测

情态动词表推测的意义：

1、大多数情态动词(除表能力、许可、意志’外)，都可以表示推测，其程度有差异。按其可能性程度的高低排列为： Must ﹥will ﹥would ﹥ought to ﹥ should ﹥ can ﹥ could﹥ may ﹥ might

肯定 完全可能 很可能 可能 有可能

2.注意区分情态动词的否定的含义：

may not或许不、可能不 might not可能不 can’t 不可能

mustn’t不许、禁止 shouldn’t不应该 needn’t 不必

3.情态动词表推测具体运用：情态动词可以对现在、进行、过去推测

S主+情态动词+be+adj 对“性质”“特征”的推测

S主+情态动词+be+n 对“职业”“事物”的推测

S主+情态动词+V原 对经常性行为的推测

S主+情态动词+be+V-ing 对进行着的行为的推测

S主+情态动词+have+PP 对过去的行为的推测

特别提醒：情态动词表推测时

1、 can只能用于否定句和疑问句

2、 must只能用于肯定句(它的否定句和疑问句其实就用can来代替了)

3、 如句中有情态动词 + 完成时，定是对过去的推测 。

4、 句中如有表示不肯定的话语，如：I am not sure; I don’t know 之类，常选may /might的各种形式

4. 记住下面几组表示反劝的特殊的表推测的形式

1). could + have + PP表示本来能做到，但事实上没有做到。 He could have finished the task on time, but the heavy snow came.

2). couldn’t +have + PP表示本来不能做到，但已经做到了。 She could not have covered the whole distance, but in fact she arrived ahead of time.

3) needn’t + have + pp表示本不必做的，但已经做到了。 She needn’t have attended the meeting yesterday, but she did.

4.) should/ought to +have + PP表示 该做而没有做 The plant is dead. I should/ought to have given ot more water.

5) shouldn’t/ oughtn’t to +have + PP表示 不该做而做了。 You oughtn’t to / shouldn’t have taken her bike without permission.

5. 记住下面对比：

must只能用于肯定句(它的否定句和疑问句其实就用can来代替了)

1.must + have + PP 表示对过去肯定的推测，译为“一定是，准是” The road is wet. It must have rained yesterday.

2.can + have + PP 表示对过去的推测(限于问句中) Can she have said so? 他可能这样说吗?

3.can’t + have + PP 表示对过去的否定推测 He cannot have said such a foolish thing.

情态动词表推测的反意疑问句

情态动词表推测的反意疑问句，简单来说，就是以情态动词后的时态为淮，如句子里有明确的时间状语，则以其为准。以 must 为例：

eg. 1. You must be hungry now, aren’t you?

2. He must be watching TV , isn’t he ?

3 Tom must have lived her for a long time, hasn’t he ?

4. She must have arrived yesterday, didn’t she?
