我觉得是不是可以这样理解：

A项 a technique called ... emission, 后面紧跟which的非限定性定语从句，修饰逗号前technique的这部分

C项 注意是 air pollutants, called ...emission，那么其实called引导的部分是修饰逗号前的air pollutants，那么就是air pollutants called ...emission，因此后面用which连接的非限定性定语从句是不对的。

其实ETS的意思不是说emission不对，而是说C项构成emission的不是A选项的technique而是air pollutants。

一点理解，不知对不对，欢迎大家继续讨论，困惑阿困惑

還是有點困惑，雖然五個選項相比，A確實是比較好。
但是對於, whuch .......應為就近修飾原則來說。
為什麼A可以被接受???
還是麻煩NN解惑!
謝謝

以下是引用dingxiang在2008-5-22 13:06:00的发言：

A:  Originally developed for detecting air pollutants, a technique called proton-induced X-ray emission, which can

C:  A technique originally developed for detecting air pollutants, called proton-induced X-ray emission, which can

我认为: 定从的指代要看其前面结构的核心词,

A里面核心词是 a technique, 分词called后面的东西是修饰的,属于从属部分,所以which不能修饰emission

C, 单单的一个分词结构, 那么which自然是指代其紧跟的名词, 不能跳跃修饰

关于定从指代的判断, 我自己总结的还有, 如果 名词+介词结构+that/which,  that/which也是修饰名词, 而非修饰介词结构中出现的名词

Agree.建议楼上的MM好好体会一下上面这段话。抓核心词很重要。

除了楼上的问题，为什么Called proton-induced X-ray emission should be placed next to a technique ？？？

同问，which的问题大家讨论得很多啊，这个也解答一下吧

fishlibai

看了这么多解释，我理解啊，c选项中，要是把逗号去掉，变成

C:  A technique originally developed for detecting air pollutants called proton-induced X-ray emission, which can ........这里which 就是指代a technique了，

因为有这个逗号，C:  A technique originally developed for detecting air pollutants ,  called proton-induced X-ray emission, which can     单单的一个分词结构, which指代其紧跟名词emission

OG解释也说should not be set off by commas

can     单单的一个分词结构, which指代其紧跟名词emission

OG解释也说should not be set off by commas

OG解释也说should not be set off by commas

我的观点：

Rhetorical construction

The original sentence successfully avoids the problems that may occur in a long sentence with multiple modifiers. The sentence opens with the modifier originally developed for detecting air pollutants. This participial phrase is immediately followed by the word technique that it modifies; technique is in turn followed by the phrase called proton-induced X-ray emission. Finally, the non-restrictive clause which ... destroying it is correctly placed next to emission and set off from the rest of the sentence by a pair of commas.  

1.gmat喜欢修饰语均匀的一前一后的分布在修饰对象的前后。

2.这里由于“名词+called”的结构修饰关系紧密，可以看做一个群体，所以which这里可以跳过called，修饰名词techniques。一般来说，which还是优先“就近修饰”。

A Correct. The modifiers are all correctly placed

B        Placement of two long modifiers at the beginning of the sentence is awkward and makes it difficult to locate the subject, second modifier (having...) actually modifies the first modifier
            

这里第二个修饰短语修饰对象有可能不是technique了，而是前一个修饰短语，逻辑上错误

C        Called proton-induced X-ray emission should be placed next to a technique and should not be set off by commas; relative clause introduced by which incorrectly and illogically modifies emission

这里由于a technique called…没有连起来，关系不紧密，
                which还是优先“就近修饰”emission

D      Called proton-induced X-ray emission should be placed next to a technique and should not be set off by commas; relative clause introduced by which incorrectly and illogically modifies emission; has the ability to is wordy  同上

E       Called proton-induced X-ray emission should be placed next to a technique and should not be set off by commas; has the ability to is wordy

The correct answer is A.

不知道大家有没有感觉，我觉得这道题A选项句子结构是“美”的，修饰部分+主语+修饰部分+谓语宾语，很平衡。。。

支持这个解释

夜色微蓝

没有大N最后出现一定乾坤，看了 http://forum.chasedream.com/GMAT_SC/thread-255026-1-1.html    

这个帖子里有CDer 的理解，还比较好接受

sth called X, which......  which指代sth;

sth, called X, which......    which 指代X；

只有这样理解还说得通，还需要进一步总结

还有一个问题

Rhetorical construction

　　A Correct. The modifiers are all correctly placed
B        Placement of two long modifiers at the beginning of the sentence is awkward and makes it difficult to locate the subject, second modifier (having...) actually modifies the first modifier








C        Called proton-induced X-ray emission should be placed next to a technique and should not be set off by commas; relative clause introduced by which incorrectly and illogically modifies emission








D      Called proton-induced X-ray emission should be placed next to a technique and should not be set off by commas; relative clause introduced by which incorrectly and illogically modifies emission; has the ability to is wordy








E       Called proton-induced X-ray emission should be placed next to a technique and should not be set off by commas; has the ability to is wordy




大家看到红笔写的地方了吗？为什么原句中说which......是the non-restrictive clause； 而CD中却是relative clause introduced by which incorrectly and illogically modifies emission;


是我钻牛角尖了吗？
