C) crests and troughs that remain stationary although the air that forms them is moving rapidly,is

E) stationary crests and troughs although they are formed by rapidly moving air, is

答案是C，解释说E incorrectly introduces a dependent adverbial although clause into a prepositional phrase (with crests...) 我不太明白它说的意思。请大家用中文解释一下

1. 将 although 从句引入 with 介词短语中是不对的。

2. Parliament believed that doing so would reward immigrants for entering the country illegally.

   doing so = accord full efugee benefits to 12 of the recent immigrants

谢了 em53]

不过还有没有更直白的解释啊?

我觉的,OG的意思是

although 引导的是个状语从句,必须在有完整的主句结构中, 状语从句才能存在

但是with介宾短语 不算是完整的主句

不过定语从句是可以的把

请NN释疑
