I don’t know if he_______ tomorrow. If he _______, I will call you.
A.will come; will comeB.will come; comes
C.comes; will comeD.comes; comes
B

试题分析:此题考查if引导的条件状语从句和宾语从句的相关知识。根据语境可知此句的含义是我不知道他明天来不来,如果来了我就给您打电话。根据语法知识可知第一个分句是if引导的宾语从句,且表示将来的动作,故用一般将来时;后半句是条件状语从句,从句用一般现在时,主句要用将来时,故选B。
点评:if既可以引导宾语从句又可以引导状语从句。if充当宾语从句的连接词时,相当于whether,词义为“是否”,遵循宾语从句的时态规则,可根据语境选择任何时态;充当从属连词,引导条件状语从句时,词义为“如果”,若主句中的谓语动词用一般将来时,则从句中的谓语动词通常用一般现在时表示将来。
