题目

____ is impolite to cut in line when you are waiting for a bus.
A even if b which C where Dso that

答案

____ is impolite to cut in line when you are waiting for a bus.
等车时加塞是不礼貌的
如果像一楼那样even if,讲不通啊,even if是一个条件状语从句,没有主句?
几个答案都不是很合适
如果让我选一个,只能选择D
so that
只有这个还免费说得过去
那么（不管怎么）说,等车时加塞是不礼貌的.
where 引导地点状语从句,which不能这样用
