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.原题 B. 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, 想问为什么A中的which可以跳跃修饰a technical 但是B中的which却只能就近修饰emmision呢?? 谢谢!! -- by 会员 Jennifer789 (2010/2/5 10:34:41)
因为B里的which与a technique之间多了一个句子,就近修饰,所以只能修饰插入的那个句子。虽然你知道是修饰a technique,但是两个定语都放在后面,就容易产生混乱。 |
