I don't know if ----- a basketball match on TV tomorrow.If there is a match,I -----it

问题描述:

I don't know if ----- a basketball match on TV tomorrow.If there is a match,I -----it
答案是there will be ;will watch

我不知道明天电视上是不是会有篮球赛,如果有,我就会看.
显然,前面的if译成了是否.并不是主将从现,不是条件句,所以前面不是现在时,而是将来时,因为说的是将来(即明天)的情况.
If there is a match,I -----it
这就是典型"主句将来时,从句现在时" 很好的体现了,主将从现.
