题目内容
I don’t know when he______ tomorrow .When he_____ , I’ll let you know.
A.comes ;comes | B.will come ; comes |
C.comes ; will come | D.came; will come |
B
解析试题分析:句意:我不知道他明天什么时候回来。当他回来的时候,我将让你知道。分析第一个句子体现宾语从句,宾语从句的特点是如果主句是一般现在时,从句用原来的时态,明天体现为将来时;第二个句子为when引导的时间状语从句,体现为主将从现的原则,从句的主语是第三人称单数,因此用comes.故选B
考点:考查动词的用法。
