107. Originally developed for detecting air pollutants........................,is finding uses in medicine, archaeology, and criminology.我很困擾問題中的which的解釋 OG在答案解是中說正確答案的which是 nonrestrictive clause 但在我選的錯誤答案C中which OG解釋那是一個relative clause and it incorrectly and illogically modifies emission. 敢問which 在正確答案中A和C中的which都放一樣的位子為啥修飾的東西會不同呢? which 在relative clause 和 non restrictive clause中到底哪裡不同呢!!!求解答!!!感謝!!!!!!

问出了我的心声啊....
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,

(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,

C的which修饰emission有什么问题呢？"proton-induced X-ray emission”作为一个整体和technique不是同一样东西吗？

AC中which的位置是一样，但是which前面的内容不一样啊。。。。

如果which修饰emission，那么后面的定语从句意思就不对了
可以说 a technique can quickly analyze
但是总不能说an emission can quickly analyze吧？

这题后来发现可以通过夹心修饰直接排除BCD.....

不是nn，只能凭我现有的知识回答你了，希望有更多人继续探讨。过去分词貌似只能紧跟在名次之后吧。假如加入逗号，也只是修饰前面的air pollutants. 也许本题考点应是这个。因此假如proton-induced X-ray emission不是指一项技术，后面的which就只是表示一个emission啦

嗯...这样好像比较能理解！！

另一张帖子的回答
关于跳跃指代

which引导非限定性定语从句时，如果前面有句子或者短语，且有明确的中心词，则which指代该中心词。如A选项中的a technique called proton-induced X-ray emission中的中心词是technique，所以which指代的是technique；
C项中which前面的短语中called proton-induced X-ray emission中没有中心词，则就近修饰emission。
