OG 13 SC 106 WHICH的用法怎么都没人问

cgycxd

106. 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, 答案是A；但是og中说C,D中的which错误指代emission，为什么A中没有指代错误？

我觉得是这样，which是只能指代名词的，具体是指代A OF B，还是A of B结构之中的B，这个要看情况。

我没看仔细说的，说错了。
但我觉得CD根本不用看到which就找到错误了：
developed for detecting air pollutants和called proton-induced X-ray emission都做定语后置修饰a technique的话，需要加连词and。如果called proton-induced X-ray emission修饰的是 air pollutants的话，逻辑错误了。

当时我的理解就没考虑which指代a technique和 proton-induced X-ray emission有什么区别，都说一个叫XXX的技术了，我就认为a technique=proton-induced X-ray emission了。我叫alzn，我就是alzn，alzn就是我啊，一样的。甚至proton-induced X-ray emission比a technique表示的范围更小，更明确。

简单来说，a technique called proton-induced X-ray emission, 这个部分和名词a technique不能分开，是essential modifier, 因此which可以修饰a technique

Ron的具体解释：

A: "(opening modifier), (noun) (modified by necessary descriptive phrase), which" - in this structure, which refers to the noun. Note that the few words right after "technique" are simply the name of that technique. These words ("technique called proton-induced X-ray emission") collectively make up the extended noun phrase to which "which" refers. The single-word noun is technique but the other words are necessary to understand what technique we're talking about.

C: "(Noun) (modifier), (modifer), which" - in this structure, we've separated what had been the necessary descriptive phrase from the noun, so it is no longer a part of any extended noun phrase. As a result, the "which" in this case really does only apply to "emission" rather than to a "technique called emission" b/c "a technique called emission" as a simple noun phrase, is no longer part of the sentence.

这题A选项很明显，which就是指代technique （ 要看到后面的VED是修饰这个technique，点出这个技术的特征）所以是technique+ved后面这个部分组成一个整体做成一个名词，被which指代

但是CD的话，就没有VED紧紧跟着来修饰technique了~

A中的 a technique called proton-induced X-ray emission是插入语，不做句子成分，which不可能指代一个可以随意拿掉而不影响句子意思的结构中的名词。

而CD中前面的called...不是插入语，所以which有指代歧义。
