语法讲解
【语法53】情态动词进行式与完成进行式
情态动词后接 be doing 或 have been doing，表示对正在发生或一直持续到现在的动作进行推测、判断或评论。
| 结构 | 含义 | 例句 |
|---|---|---|
| must be doing | 肯定正在做 | She must be doing her homework.（她一定在做作业） |
| can't be doing | 不可能正在做 | He can't be sleeping. The lights are on.（他不可能在睡觉，灯还亮着） |
| may/might/could be doing | 可能正在做 | They might be watching a movie.（他们可能在看电影） |
| should be doing | 应该正在做 | You should be studying for the test.（你应该在复习考试） |
| must have been doing | 肯定一直在做 | She looks exhausted. She must have been working all day. |
| can't have been doing | 不可能一直在做 | He was in class, so he can't have been playing games. |
| may/might/could have been doing | 可能一直在做 | It smells like smoke. Someone may have been cooking. |
| should have been doing | 本应该一直在做 | You should have been saving money.（你本应该一直在存钱） |
与情态动词完成式（must have done）的区别： - must have done 强调动作已经完成或对过去结果的推测。 - must have been doing 强调动作在过去一段时间内持续进行。
