1.should have done 本应该做而实际未做,表示后悔的虚拟语气.
2.shouln't have done 本不应该做而实际做了.如:he was very sad now. I shouldn't have scolded him.
3.could have done 表示本可以(有能力)做,而实际未做.I could have finished my work on time, but I wasted a lot of time chatting on line.
4.couldn't have done 与前三者不一样,不表示后悔,责备的语气.而表示比较肯定的猜测语气,翻译为:(过去)不可能做.如:Tom couldn't have broken the window,beause he was watching TV at home at that moment.
在modal verb後加n't通常都是否定的意思
例如you should do your homework
意思是你应该做家课
但如果should後加n't
即shouldn't
变成you shouldn't do your homework
意思变成完全相反
即你不应该做家课
本来不应该做却做了,本来不能却能做,本来应该做却没做,本来能做却没做
