标题: 大全567/补充208

1. 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,（A）

(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

A可以选对，但是有疑问，

A中which的先行词是x-rany emission对吗，如果是，那么x-rany emission怎么发出分析analyze这个动作呐？

这正是这里用非限定性定语从句的原因.

如果a technique called proton-induced x-ray emission, which这里不用逗号, 则逻辑上指代了a technique, 语法上指代了x-ray emission.

但是用(,which)其语法指代可能是a technique或x-ray emission. 这里x-ray emission的指代在逻辑上不通. 所以逻辑清晰指代a technique语法上也不违反

仔细看看指代dispbbs.asp?boardID=23&ID=43552&page=2

都是NN的解释
