I don't know when he ____ back tomorrow.Don't worry,I 'll call you when he____ back.will come,comes.求说明.
I don't know when he ____ back tomorrow.Don't worry,I 'll call you when he____ back.
will come,comes.求说明.

I don't know when he ____ back tomorrow.Don't worry,I 'll call you when he____ back.will come,comes.求说明.
I don't know when he __back tomorrow.
I don't know 是主句
因为know 是及物动词,所以　when he __back tomorrow 其实是一个宾语从句.根据时间状语tomorrow,我们知道这句话表示将来时态.所以第一个空填 will come.
我不知道他什么时候回来.
第二句话的意思是,当他回来的时候我会给你打电话.I will call you是主句,when 引导的是个时间状语从句.时间状语从句的原则是“主将从现”即：主句用一般将来时,从句用一般现在时表示将来.所以,when 引导的时间状语从句中用 when he comes back 而不是will come back.

第一句tomorrow是明天，将来时候，当然用will come
第二句 when引导的时间状语从句记住四个字主将从现
也就是主语将来时，从句就用现在时所以用comes
主将从西现的还有 if 这个词
这是考点。。。。请牢记

will come, comes
第一个空是when引导的宾语从句，做know的宾语，when翻译为“何时”；
第二个空是when引导的时间状语从句，when翻译为“当......”。
注意看清句子意思再做题。

第一空考查宾语从句中时态，表将来，用一般将来时。
第二空考查时间状语从句中时态，从句要用一般现在时表将来。

前一空，因为有时间状语tomorrow，所以要用will come，一般将来时，后一空，为时间状语，主将从现，用comes ，一般现在时，同样的还有If引导的条件状语从句
