条件状语从句遵循，主将从一，若主语是过去将来时，那从句是何种语态，若主语是过去完成时那？

Question

如题所述

Answer 1

你好。两种可能：
1 He said that he would come if his work WAS over before 5:00 pm. (一般过去时)

2 He said that he would come if he HAD FINISHED his work before 5:00 pm. (过去完成时)

3 He said that he would have done all his work by 5:00 pm if nobody WAS to interrupt him. (一般过去时)

4 若主语是过去完成时那？-------这种结构在英语中不存在，呵呵。追问

the teachear said he would fail me if i don't work harder.中为什么主语是过去将来时，而从句用一般现在时。有主语是过去将来完成时，从句是过去完成时的情况吗？

追答

你好。不管这一句是从哪里来的，The teachear said he would fail me if i don't work harder.是错句。应该是：The teachear said he would fail me if i didn't work harder.--------注意，时态必须保持一致。

追问

真的错了，必须保持一致吗？这是《新概念英语2》的句子
有主语是过去将来完成时，从句是过去完成时的情况吗？

追答

1 是《新概念英语2》课文，还是中国人编写的练习？
2 有主语是过去将来完成时，从句是过去完成时的情况-------- she said that she would take me out to dinner IF i had finished all my homework before 6:30 pm.== she said that she would take me out to dinner IF i finished all my homework before 6:30 pm.
(你自己回顾一下你所学过的英语时态知识吧)

Answer 2

指将来条件时：主将、从现；
指过去条件时：主句过去将来、从句一般过去。
