can you tell me when you ___ if it ___ tomorrow?

题目

can you tell me when you ___ if it ___ tomorrow?
A:arrive; doesn't rain
B:will arrive; won't rain
C:will arrive; doesn't rain

答案

C
这个是从句套从句
分开看：
can you tell me when you will arrive?你能告诉我你明天什么时候来吗?（宾语从句,明天没有发生,因此用将来时）
后边看成一个整体：
when will you arrive if it doesn't rain tomorrow.如果明天不下雨,你什么时候来?（if引导的条件状语从句中,主句用将来时,从句用一般现在时）
因此选C
