选项 A、Originally developed for detecting air pollutants, a technique called proton-induced x-rays 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 element in almost any substance without destroying it, a technique called proton-induced x-rays emission
C、A technique originally developed for detecting air pollutants, called proton-induced x-rays 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-rays 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-rays emission,
答案 A
解析 A中a technique作developed短语的逻辑主语，which引导的非限定性从句修饰a technique，修饰关系明确，无歧义。B、C、D、E在修饰关系上都存在缺陷。在B中，由于developed短语与having短语之间无and连接，就表明having短语是修饰最近的名词air pollution，改变了句意。C中，developed短语与called短语之间也无and连接，因而表明called短语修饰最近的名词air pollutants，也改变了原意。D中，(1)缺陷同C；(2)without前有and，就表明without短语与前面的in短语是并列关系，导致句意分裂。E中(1)同D(2)；(2)the substance可用it来代替；(3)called短语由本应用于修饰a technique，却被改为修饰the substance，歪曲了原意。
