Question

英语中各种时态的比较专业的翻译！

一般现在时：He does his homework. 翻译：他做作业
一般将来时：He will do his homework. 他将做作业。
现在完成时：He has done his homework. 他做了作业。
问：：
过去完成时、现在完成进行时、过去将来完成进行时的被动语态的翻译（若有专业的最好，这些时态虽不常用，可科学文里一定出现过）。
（即He had done his homework、He has been doing his homework、His homework would have been being done by he. ）

Answer 1

过去完成时 he had done homework by then.他那时已经做完作业。
现在完成进行时 he has been doing homework.直到现在他一直在做作业
his home work would have been deing done.
他过去一直在做作业

其实这几种时态都要有时间状态的，单独抽出来，语法上不对的

Answer 2

他（过去）把作业做完了。
他一直在做作业。（形容时间长和持续性）
他（过去）一直在做作业。（突出过去，时间长和持续性）
