OG 205

清清小蚂蚁

以下是引用jeffyang在2003-11-14 12:09:00的发言：
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

怎么没看懂呢，有哪位再用浅显易懂的话讲一下呢？？？？？

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。
            

介词短语结构不能带转折从句,另外E的意思也和原文不符. 所以选C

them指代什么呢? 我认为是crests and troughs, 是否正确?

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."

题干中的acting like是怎么个使用方法？我只记得有act as这个使用方法阿？难道说act后面跟as和like都可以，都表示比较，只是as接句子like接名词吗？

希望大家解答

有没有人知道， 为什么the resulting flow pattern are know as "standing waves." 为什么不是wave， 这样才能和pattern统一成单数啊？

在OG开篇的“Basic English Grammar Rules"里面有提到

As／like．As can be a preposition meaning“in the capacity of, ”but more often is a conjunction of manner and is followed by a verb．Like is generally used as a preposition．and therefore is followed by a noun, an object pronoun, or a verb ending in “ing.”

这里根据题意,不是作为能力来讲，like 后面的是名词，所以，我认为用like没问题

205. The peaks of a mountain range, acting like rocks in a streambed, produce ripples（波纹） 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  [although引导的状语从句只能用于引导含动词的结构，如修饰名词性词组，将失去修饰对象]

 

状语只能修饰动词、形容词，不能修饰名词性词组；

D\E都是名词性词组，缺乏C中的remain ....   ,因此，此后的although无修饰对象。

 

看了20分钟，终于明白。。。。
