情态动词+have done

①情态动词must +have done只用于肯定句中,表示对过去发生的事情或状态进行肯定的推测,意为“过去一定做过某事”。

②情态动词can/could可用于否定句中,即can’t have done /couldn’t have done,表示对过去发生的事情或状态的肯定的推测,意为“过去不可能做过,肯定没做过某事”。

③此外,can/could have done还可用于疑问句中表示对过去发生的事情或状态的不太有把握的推测,意为“过去可能做过……吗?”

注意:表推测的情态动词只有can/could,常用于疑问句中。

④情态动词may/might +have done表示对已发生的动作或存在的状态进行不肯定的推测,might语气稍弱一点儿,只能用于肯定句和否定句中,意为“过去可能做过某事或过去可能没做过某事”。
