couldn't have done 表示什么
Jim!Did you have a good time at the party?
Yes,but I really _____ have because I had a lot of work to do.
A shouldn’t
B couldn’t
注解说是对过去发生的事情的否定猜测用couldn’t have done ,我不明.明明不是参加了吗?不是用shouldn’t have done “本不该”
couldn't have done 表示什么Jim!Did you have a good time at the party?Yes,but I really _____ have because I had a lot of work to do.A shouldn’t B couldn’t 注解说是对过去发生的事情的否定猜测用couldn’t have done ,我不明.
可以这么想:
could have done是说本来可能做而没有做.那么,couldn't have done就是本来不可能做却做了.
因为有很多工作,本来不能玩得很开心的,却在聚会上玩得很开心.
如果句子是下面这样,就应该用shouldn't.
- Did you go to the party?
- yes.But I really shouldn't have because I had a lot of work to do.
这里是虚拟语气
B couldn’t
