(1)我1个月前我就完成了6道题目了,
I finished six questions one month ago。
I have already finished six questions one month ago。
这两句都对吗?不同的时态意思表达上有什么区别吗?
(2)但是现在仍然在作第七道题。
But i am still doing the seventh question。
(3)我问过老师这题。
I have asked teacher for help。
I asked teacher for help。
同(1)一样问题,表达意思上有什么不同呢?
都对吗?
(4)老师说他做完后会发E-MAIL给我。
He said he would send the email to me after he finished it。
这里的 finish 用过去式对吗?。
