标题: OG15 SC106 [打印本页] 作者: steffifu 时间: 2015-7-16 00:25 标题: OG15 SC106 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,
请问，在解释中，为什么 （A）的 which 修饰的是 a technique, 而（C）的which 却修饰的是emission？
原则上来说which只能贴身修饰，A中语义上which肯定是修饰technique，语法上够不够得着，表示不清楚作者: erkuai9526 时间: 2015-8-27 13:56
我从曼哈顿直接贴过来哈
The difference is in the placement of the various phrases.
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.作者: 发动机 时间: 2015-9-24 17:23
