高考虚拟语气：情态动词+have+过去分词

情态动词

一、定义

情态动词本身具有一定的词义，需与动词原形结合使用，以增加谓语动词的情态色彩，表达说话人对行为或事物的态度和看法，如可能性、必要性等。

二、分类

情态动词分为四类：

①做情态动词：must, can(could), may(might), ought to

②可做情态动词又可做实义动词：need, dare

③可做情态动词又可做助动词：shall(should), will(would)

④具有情态动词特征：have(had) to, used to

三、常用情态动词的用法

1. must和have to表示必要性

2. can’t表示不可能，mustn’t表示不允许或禁止

3. don’t have to和needn’t表示没有必要

4. can 和could 表示能力和可能性，还可表示请求允许

5. must, might, could表示猜想和推测

6. may表示可能和允许

四、情态动词+have+过去分词

1. “must+have+done”表示对过去事情的肯定推测，译成“一定做过某事”，该结构只用于肯定句。

（1）It must have rained last night, for the ground is wet.

（2）You must have been mad to speak to the servant.

2. “can’t+have+done”表示对过去事情的否定推测，译成“不可能做过某事”。

（1）Mr. Smith can’t have gone to Beijing, for I saw him in the library just now.

（2）Mary can't have stolen your money. She has gone home.

3. “can+have+done”表示对过去行为的怀疑，用于疑问句，译成“可能做过……吗？”

（1）There is no light in the room. Can they have gone out?

（2）There is nowhere to find them. Where can they have gone?

4. “could+have+done”是虚拟语气，表示对过去事情的假设，意思是本来能够做某事而没有做。

5. “may+have+done”表示对发生过去的事情的推测，意思是“可能已经”或“也许已经”，用于肯定句中。

6.“might+have+done”表示对过去事情的推测，might与may意思相同，但可能性更小。多用于虚拟语气结构中。

7. “should+have+done”意思是“本来应该做某事，而实际没做。” “shouldn't+have+done”表示本来不应该做某事，而实际做了。含有指责对方或自责的含意。

8. “ought to+have+done”表示过去应该做而实际并没有做，译成“理应做……”，往往表示遗憾。与“should+have+done”用法基本一样。
