a English question,welcome any master~
-do you know when the teacher----back?
-sorry,i don't know.if he ---back,i'll tell you at once.
答案是will come comes
我想知道怎么用语法来解释这道题~自己是知道怎么选,别人问我却不知该怎么说~

第一空问得是“老师什么时候会回来”,就是说老师还没回来,但即将回来,再看“DO YOU KNOW”是一般现在时,因此要用一般将来时
第二句“If he ---back,i'll tell you at once.”是一“IF”状语从句,在语法上有规定:主句若是一般将来时,从句要用一般现在时.在这里,“i'll tell you at once”是主句,因此应填一般现在时

第一空用一般将来时,所以用will come
第二空条件状语从句,从句用一般现在时,所以用comes

此题是说,老师什么时候回来,说明他还没有回来,所以第一空用的是一般将来时。后面说他一回来,我就马上告诉你,是if的用法,译为:一......就......。所以用一般现在时

我觉得这样更好
is coming
comes

是an English question!!1
看来你语法不好,建议你买本语法规则带练习的书
从do,know看出主句用的是一般现在时,事情还未发生,从句就用一般将来时。
第二句没什么语法规则,直接看he是单三,谓语根据主语变化就行了。
