might是may的过去式,可为什么you might also get a headache when you work work

might是may的过去式,可为什么you might also get a headache when you work work might是不是may的过去式/ 我们老师说：“情态动词无时态,人称的变化.”可他又说can的过去式是could,may的过去式是might,这是怎么回事呀? may 的过去式might的用法? may 的过去式 might . 为什么有时候现在时态也用might? 除了虚拟语气还有其他么? I might have some pets.中,为什么用may的过去式 can的过去式是could吗?may的过去式是might吗?shall的过去式是should吗?will的过去式是would吗? might为什么在将来时句子出现?如 some will look like humans ,and others might look like snakes.might 不是may的过去式吗 might不是may的过去式时 它也是情态动词? he may have telephoned last night,but i'm not sure.may的过去式不是might 情态动词 过去式情态动词是不是没有过去式的啊 好像should need（情态）都没有过去式.还有 might 是不是有两种意思 一种是情态动词may的过去式 第二种是 表 推测 还有别的意思吗? -what do you think the noise was?-It _____a cat.A may be B might be C could have been D might have been可为什么答案写的是D呢？ He_you more help even though he was very busy.A,might have givenB.might giveC.may have givenD.may give想问问这道题为什么选A不选C,我这样想的:句中用了一般过去式,might是may的过去式,其实两项都可以,不过A是更好的 I might even keep a pet parrot!为什么用过去式,我甚至要养一只鹦鹉,是将来才对还有I might even visit Australia也是might的问题 might may的区别 might是不是may的过去式might既是may的过去式又是情态动词?还有一个问题：may在表示许可、用于请求或征得对方的许可时,可用be allowed to的相应形式代替.那是不是就是说may可以用are allowed to来代 might be和 may have been的区别?还有是might do和 may have done 一个英语填空题的解释She said she might not see her son for another two years.这句话里为什么用might,是不是用的may的过去式?能不能用could?为什么?这句话怎么翻译?
