(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,
正確答案是A
疑惑的地方是C和D
在OG11的解釋分別如下
C Called proton-induced X-ray emission should be placed next to a technique and should not be set off by commas; relative clause introduced by which incorrectly and illogically modifies emission
D Called proton-induced X-ray emission should be placed next to a technique and should not be set off by commas; relative clause introduced by which incorrectly and illogically modifies emission; has the ability to is wordy
為什麼C,D的which 不能修飾emission? 哪裡illogical?
正確答案A的which 為什麼可以修飾emission?
想了一陣子了
