OG 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."

crests and troughs that remain stationary although the air that forms them is moving rapidly, are
crests and troughs that remain stationary although they are formed by rapidly moving air, are
crests and troughs that remain stationary although the air that forms them is moving rapidly, is
stationary crests and troughs although the air that forms them is moving rapidly, are
stationary crests and troughs although they are formed by rapidly moving air, is

The main challenge in this sentence is to observe the agreement of subject and verb (the resulting flow pattern... is known...) despite the distraction of a complex intervening structure containing several plural elements (with crests and troughs...). Choices A, B, and D can, therefore, be eliminated because they use an incorrect plural verb form, are. Choice E uses the correct verb form, is, but it incorrectly introduces a dependent adverbial although clause into a prepositional phrase (with crests ...). Choice D also makes this error. Such dependent clauses can only occur in the predicates of full clauses. C, the best choice, uses the correct verb form, is, and correctly puts the although clause inside the predicate of the relative clause (that... rapidly).

我对although的位置不大理解,不知哪位能讲讲?谢谢.

偶也刚看了这个题，还想了一会会。og的解释上说but it incorrectly introduces a
dependent adverbial although clause into a prepositional phrase (with crests ...).
偶在想是不是类似于although的这种表让步的从属连词引导的从句不可以出现在介词词组
中，抑或是所有的从属连词引导的从句都不可以，请指教。

是不是although 这个词,只能出现在独立的从句中?能讲讲吗?谢谢.

如果把这句话变成
The peaks of a mountain range, acting like rocks in a streambed, produce ripples in the air flowing over them; the resulting flow pattern is known as 'standing waves.'。
Those crests and troughs remain stationary although the air that forms them is moving rapidly.
好理解了吗？
事实上从句子的结构上讲就是WITH+名词（CRESTS AND TROUGHS）而后面是THAT引到的是一个定语从句，修饰CRESTS AND TROUGHS，而在这个从句中又有一个 用ALTHOUGH连接的转折分句。
但是在E中，没有‘THAT’情况就会很惨，因为WITH后怎么可能有一个ALTHOUGH的句子呢？

Although S1 + V1 , S2 + V2.
其中 although S1+V1 是屬於 adv.clause ,  修飾 main clause 的 V2

而#205 在兩個"," 之間有個 prep.phr (with crests and ....)他沒有動詞V ,
所以如果這裡放進去一個adv.clause ( although the air ...is moving ) 或是 (although they are formed..), 那這個 adv.clause就不知道要修飾哪裡了

這是小弟的淺見

有道理.

如果是prep phr. with crests and ..that.... although ....呢?
