105. Originally developed for detecting air pollutants, a technique called proton-induced x-ray emission, which can quickly analyze the chemical elements in almost any substance without destroying it, is finding uses in medicine, archaeology, and criminology.

(A) Originally developed for detecting air pollutants, a technique called proton-induced x-ray emission, which can quickly analyze the chemical elements in almost any substance without destroying it,

(B) Originally developed for detecting air pollutants, having the ability to analyze the chemical elements in almost any substance without destroying it, a technique called proton induced x-ray emission

(C) A technique originally developed for detecting air pollutants, called proton-induced x-ray emission, which can quickly analyze the chemical elements in almost any substance without destroying it,

(D) A technique originally developed for detecting air pollutants, called proton-induced x-ray emission, which has the ability to analyze the chemical elements in almost any substance quickly and without destroying it,

(E) A technique that was originally developed for detecting air pollutants and has the ability to analyze the chemical elements in almost any substance quickly and without destroying the substance, called proton-induced x-ray emission,

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.

　　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

The correct answer is A.

以上是OG的解答，我想问的是C&D都说which不指代 emission，那推测应该是指代technique，可是他们都跟A一样接在emission，怎么办别他是在修饰techniuqe而不是emission？

好像它说的是，错误的和不和逻辑的修饰了emission吧，也就是说这里which指代了emission.因为A called B这种结构中called后面与A关系密切，只是作修饰成分，定语从句还是修饰A的，而且called修饰不宜与它要修饰的成分分开的。

谢谢xiaowan

我也是这样想的　不过映像中好像只有Ａ　ｏｆ　Ｂ结构才是这个样子

不知道有没有例句，确定以下

A of B结构后的which定语从句不一定是修饰A的，可能是修饰B的，判断方法1，A前面有没有定冠词等限定2定语从句的谓语动词与谁一致

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.

relative clause introduced by which incorrectly and illogically modifies emission

这两句话不是自相矛盾？

relative clause introduced by which incorrectly and illogically modifies emission

这两句话不是自相矛盾？

对于这种非限制性定语从句所修饰的先行词我一直很困惑，是不是非限制性定语从句不用紧跟在先行词后面？

反正记住which和it都不能指代前面整句，而且只能就近修饰这个点就可以了。这样上面的题就可以很容易排除
