OG 12-107关于which指代（菜鸟提问）

evangelia

不讨论答案，只讨论which指代问题

原题：Originally developed for detecting air pollutants,a technique called proton-indeced 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.原句

C. A techonology 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 techonology 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 without destroying it.
正确答案是A，OG解释是The nonrestrictive clause, which....destroying it  is correctly placed next to emission.
选项C、D中，which出现的形式雷同，A techinique...,called proton-induced X-ray emission, which can...这里的which OG上说是修饰emission
为什么在A当中which修饰的对象就是正确的，到了C、D当中就就近指代emission了呢？期待NN解释

prayer，解释得好.

prayer

called proton-induced X-ray emission是分词修饰a technique的，必须紧挨着他，所以必须放到最前面。which也需要修饰前面紧挨着的名词，两个修饰词不能放到一起。

a technique called proton-indeced X-ray emission,which

called proton-indeced X-ray emission，是用来修饰a technique的，从gmac的语法上讲，which是修饰eligible noun，这里a technique才是eligible noun。

看样子“名词＋called的结构”类似“名词+of结构”，还有什么结构被GMAC认可which可以跳过修饰的？哪位NN来总结一下。

啊刚看到了，白勇平行58说，名词＋called的结构，修饰关系紧密，可以看作一个整体，所以which定从能够跳过called……修饰名词technique

照C，D的解释A中的which应该指代a technical，为什么这里which就不是就近指代了，同样期待nn
