你好。
1 I might have killed a man last night.是表猜测== It is possible that I killed a man last night.
2 I could have fooled you (if I had wanted to). -------这是虚拟语气,假设过去的事情。一般来说,情态动词 + 完成式 -------指代已经过去的事情。
it was possible that she was writing at that time == She might be writing at that time 情态动词+进行式。
it was possible that she was a nurse at that time == she might be a nurse at that time 情态动词+过去式------这个“过去式”体现在“情态动词”上面:may --- might
追问你好 谢谢解答
一般来说,情态动词 + 完成式 -------指代已经过去的事情。
但是I might have killed a man last night.也是这个情况 就不是虚拟了?
追答nihao.一般来说,在没有 “if -- - - -”结构伴随的情况下,may / might不属於“虚拟”的范畴。would和could是“虚拟”的首选。
