the time is not far away when mobile phones___widespread in China's vase countryside

问题描述:

the time is not far away when mobile phones___widespread in China's vase countryside
A.will become B.become C.shall become D.have become
我选B,觉得将来时有点别扭.
不是翻译,是解释一下为什么用将来时,我读着挺别扭的~谢过~

when在这里引导的是修饰主语time的定语从句,关系副词when可代替的先行词是时间;而不是时间状语从句.按其文意是要表达将来时.
