I don’t know if he ________ back tomorrow. If he ______ back, I’ll let you know.
A. comes; will come B. will come; came C. will come; comes

C

if翻译为是否，属于宾语从句。如果主句是一般现在时，从句根据需要选择时态，如果主句是过去时态，从句要用相应的过去时态。该句主句是一般现在时，故根据句意从句用一般将来时。在if引导的条件状语从句中，如果两个动作都没有发生，为了区别动作的前后关系，先发生的用一般现在时态，后发生的用一般将来时态，即主将从现。句意：我不知道明天是否他会回来。如果他回来了我会告诉你。故选C。
