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,

    

答案选A，但是为什么C不对呢？OG说A选项是非限定性从句，但同样由which引导的从句在C里为什么叫relative clause? 两者到底区别在哪里呢？我对什么是非限定性从句，什么是限定性从句还是不太明白，谁能讲讲？

句子结构为:

句首分词短语(修饰主语a technique ),主语a technique +分词短语 called proton-induced X-ray emission(同样修饰主语),插入语(which引导非限制性定语从句跳跃分词短语修饰主语a technique ),+谓语 is finding +宾语.

C的主要错误在于called proton-induced X-ray emission位置不对,修饰对象模糊有歧义.而且主语与谓语中间插入过多成分导致句子结构模糊.

至于LZ提出的"which引导的从句在C里为什么叫relative clause",本人同样存在置疑,但由于其与应该的修饰对象a technique 间隔过远,因而只能修饰emission,此时逻辑含义不合理,因而错误.且本人建议有些时候不要绝对使用which来作为决策关键排除选项,which的修饰用法在不同的句子结构中修饰对象有时真的是"千变万化".

限制性定语从句与非限制性定语从句的区别是:

限制性定语从句强调部分;

非限制性定语从句强调整体.

非常感谢你的解释！看了半天置顶贴关于非限定性从句和限定性从句的解释，现在已经明白了！对于你说的:"且本人建议有些时候不要绝对使用which来作为决策关键排除选项,which的修饰用法在不同的句子结构中修饰对象有时真的是"千变万化"." 我非常同意。which所修饰的对象不仅仅要看语法，而且逻辑意义也很重要。
