205. The peaks of a mountain range, acting like rocks in a streambed, produce ripples in the air flowing over them; the resulting flow pattern, with crests and troughs that remain stationary although the air that forms them is moving rapidly, are known as "standing waves."
(A)    crests and troughs that remain stationary although the air that forms them is moving rapidly, are
(B)    crests and troughs that remain stationary although they are formed by rapidly moving air, are
(C)    crests and troughs that remain stationary although the air that forms them is moving rapidly, is
(D)    stationary crests and troughs although the air that forms them is moving rapidly, are
(E)    stationary crests and troughs although they are formed by rapidly moving air, is
答案是c，e 为什么不对？

E中的although从句用的不对， 就好比说中文，只有虽然的上半句， 没有但是的下半句。C中的although用的是完整的。

"crests and troughs that remain stationary"中的remain不可省，所以不能按adj+n优于n+that adj来改

类似的还有come , go, become, remain都不能去掉或换为be动词

八戒

在c中stationary在remain的后面，表示一种状态！

而在e中，stationary做为adj修饰crests and troughs ，表示一种特征！

再问一下,为什么 the resulting flow pattern is known as "standing waves.",
wave要加 s 呢? 谢谢解答

我觉得因为有那个引号的存在，说明这是一种现象或是一个概念，所以没有必要分析里面的单复数，不管是单数复数只要是一个概念，就是单数。

hehe，今天想出了一个例子：......的现象 is“万兽狂奔”。很显然，这里的“万兽”，就是复数，但是是说的一个概念，所以谓语动词要用单数。跟里面的没有关系。
