OG12 107 - OG解释矛盾了？

107 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 techinique called proton-induced X-ray emission, which can quickly analyze the chemical elements in almost any substance without destroying it,

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,

正确答案选A，按OG的说法是因为A: This participial phrase is immediately followed by the word technique that it modifies; technique is in turn followed by the phrase called proton-induced X-ray emission. Finally the nonrestrictive clause which...destroying it is correctly placed next to emission and set off from the rest of the sentence by a pair of commas.

而针对为何C错，OG解释是：Called proton-induced X-ray emission should be placed next to a technique and should not be set off by cocmmas; relative clause introduced by which incorrectly and illogically modifies emission.

撇开其他方面不说，A和C的共同之处就在于emission后面都被逗号隔开，有which开头的非限定从句，这样看来which引导的从句无论是在A还是C里，都是在修饰emission的，不是吗？为什么A里which的位置就是对的，而C里就错了呢？

多谢牛牛指教~！！

我想在og对c地解释中，relative一词很重要。 也就是说，因为called短语修饰位置的错误，导致which从句修饰emission改变了整个句子的逻辑结构。而不是单纯就which放在这个位置，是不是修饰emission而言的。which从句肯定是修饰emission没错。

谢谢xfi882牛牛，那这样看的话，A里which就不是修饰emission，而是修饰technique了吗..？非限定从句难道不是修饰离which最近的事物吗...?

不好意思我喜欢钻牛角尖>.<

按照逻辑,A里面的which从句确实是修饰tech；C里面修饰的是air pollution。但是从语法角度讲，这两个which从句都是修饰emission

不明白就接着问。我该睡觉了，夜里3点多了。快！

which在两个选项里都是离emission近，那都是修饰emission而非technique的对吧?

按xfi883你的理解是不是因为C里emission位置错导致句子逻辑结构错？那再弱弱地问一下哦：A和C因emission位置改变而产生了怎样逻辑的不同呢...？

我知道我很啰嗦...不过还是想弄清楚..谢谢~

不是因为emission位置错，而是a tech位置错。我相信你已经知道了为什么C不正确了吧。

别客气。你问得不弱！嗬嗬

天啊..xfi883你在美国吗怎么这么晚，我们这里才6点过而已..

辛苦辛苦，你先睡吧，真是不好意思！！！

别，我不喜欢半途而废。你尽管问。你不是在中国吧。中国现在应该是下午4点。快问吧，我得给你回答明白了。

好，那我继续了哦..

C里a tech位置错吗？但是OG明确指出是called...位置错，应放在a tech旁边..

C里逻辑怎么不对了呢？which怎么又变成修饰air pollutats了呀？

我在澳洲呢
