问题描述:

the wet weather will continue tomorrow when a cold front _____ to arrive.
A.is expect B.is expecting C.expects D.will be expected
为什么不选D呢?明天的话不应该用将来时么?

选C 一般现在时表将来
come, go, arrive, leave, start, begin, return等动词的一般现在时表将来。这主要用来表示在时间上已确定或安排好的事情。
The bus leaves at six tomorrow morning.
When does the bus start? It starts in ten minutes.
希望有帮到你哦~

A.is expected 写错了是吧,答案应该写选这个
首先肯定是被动语态,when 也存在主将从现的用法.主句用了将来时,从句用现在时
