have 后接 done,have not 接什么形式

have 后接 done,have not 接什么形式 为什么动词不定式后可以接have done?是什么句型? 关于 should have done 等.1.书上说should后接完成时态,即should have done 表示 责备 应该做而实际上没有做.那有没有should had done 2.我知道有 should have done ought to have done must have done need have done would have d I have no idea as to how it is done. Could have done would have done should have done must have been done must have done have done与have be done would have done,might have done,could have done,should have done分别表示什么意思? may have done和may have done 的区别RTmay have done和might have done should have done ,shouldn't have done.could have done,couldn't have done have+done是什么时态? have sth done意思 we have done our 情态动词+have done what have u done could never have done have sth done have done是什么时态
