“情态动词+ have +过去分词”是英语学习中的重点之一,淘教中国网根据本文将就“情态动词+ have +过去分词”的用法做具体解析,希望对大家有所帮助。
1)may(might) have + done sth, can (could) have + done sth 表示过去,推测过去时间里可能发生的事情。例如:
Philip may (might) have been hurt seriously in the car accident. 菲力浦可能在车祸中受了重伤。
Philip can (could) have been hurt seriously in the car accident.
2)must have +done sth,对过去时间里可能发生的事情的推测,语气较强,具有"肯定","谅必"的意思。例如:
——Linda has gone to work, but her bicycle is still here. 琳达已经去上班了,但她的单车还在这儿。
——She must have gone by bus.肯定乘巴士去的。
3)ought to have done sth, should have done sth表示本应该做某事,而事实上并没有做。否定句表示"不该做某事而做了".例如:
You ought to (should) have been more careful in this experiment. 你当时在做试验时应该更仔细点。
He ought not to have thrown the old clothes away.他不该把旧衣服扔了。(事实上已扔了。)
ought to 在语气上比should 要强。
4)neednt have done sth表示本没必要做某事,但做了。例如:
I dressed very warmly for the trip, but I neednt have done so. The weather was hot.
旅行时,我衣服穿得较多,其实没有必要。那时天很热。
