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,
再问： 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？
再答：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。
再问：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？
再答： 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)

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? if条件状语从句我现在就知道,主将现从.那主语是过去时,从句时什么时态?主要是怎么变化?处虚拟语气时间状语从句是主将从现吗,那条件状语从句和宾语从句呢主将从现问题在时间状语从句中,如果主语不是一般将来时(是一般现在时或其他),可不可以用一般现在时表将来时? 是不是时间或条件状语从句为一般现在时,那主句一定是将来时? 关于英语从句的问题.英语中有主将从现的原则,但是条件好像是主句要为祈使句或将来时的句子,从句应是时间状语从句或条件状语从 If 引导的条件状语从句中,从句可以是将来时吗?为什么,如果可以那主句是什么时态? if条件状语从句有一些是主将从现,if后加的是一般现在时,但有些又是加的将来时.怎样区别? 是状语从句还是主语从句主将从现它成分是由时间状语从句和条件状语从句构成关于主将从现好像是状语从句省略主语,成简单句,能不能讲一下用法之类的主句是过去将来时,if引导的条件状语从句用什么时态
