对Perhaps 和表示可能后的答案是He might have gone home early.为什么might后面用 (他可能看过) the film before 为什么填 Could he have seen?我用的是might. 10.he might have gone a step . might be和 may have been的区别?还有是might do和 may have done can/could have done 和may/ might have done 表示对过去发生事情的猜测 哪一组可能 She might have gone.她或许已经走了.　句中为什么用have不用had? 英语翻译这里的might 怎么翻译?为什么是might he might have given you more help,but he was very busy 为什么是m might have 怎么用? had he gone to the doctor right away ,he might have been ali He may have been busy和He might be busy he might have telephoned last night.为什么是完成时?时间状语不是last night
