问题描述:

I donn't know when my father___.But if he ___I'll tell him about that.
A.will come;comesB.comes;will comeC.comes;comesD.will come;will come

答案是A。

A。第一个句子表达我不知道我的父亲会不会来,用将来时。
第二句,在从句中,用一般现在时表示将来时,所以用comes

A 第二个空:if引导的条件状语从句,主句将来时,从句一般现在时表将来

A~~祈使句

I donn't know when my father (will come).But if he (comes),I'll tell him about that.我不知道我父亲是否会来.但如果他来的话,我会告诉他那件事的.要选择A项.第一句含有宾语从句,从句是将来时态.第二句是if...

选A
前面是将来时,没有问题
后面一句是“主将从现” 主句将来时从句一般现在时。
