6. In virtually all types of tissue in every animal species, dioxin induces the production of enzymes that are the organism's trying to metabolize, or render harmless. the chemical that is irritating it.

(A)              trying to metabolize, or render harmless, the chemical that is irritating it

(B)            trying that it metabolize, or render harmless, the . chemical irritant

(C)            attempt to try to metabolize, or render harmless, such a chemical irritant

(D)          attempt to try and metabolize, or render harm­less, the chemical irritating it

(E)            attempt to metabolize, or render harmless, the chemical irritant

the answer is E, but I cann't figure out "the chemical irritant", if "harmless" modifies  it, why are there a "," and "the". Do you think it will be better if "," and  "the " are deleted.  Hope someone can answer the question, sorry that my computer can not print Chinese

1.不能去掉the， 因为irritant是可数名词，所以必须用the 或者a或者复数修饰

2.不能去掉“，”，因为，irritant同时也做metabolize的宾语

这是以前一个NN写的，原贴我找不到了，就把内容贴给你看吧，希望有帮助：

attempt to metabolize, or render harmless, the chemical irritant

attempt to metabolize, or render harmless, the chemical irritant.

其实这是老美最爱用的由＂轻到重＂的写作方式,OG另有不少例子,一时想不起来,就不误导人了.所谓＂由轻到重＂就是宾语补语(O.C.)较宾语(O.)短时,老美会将宾语补语移到宾语前,让句子结构呈现头轻脚重的形式,这种写作方式很常见.只是外国学生不大习惯,总觉念起来不是很顺.

所以本答案原句为: attempt to metabolize, or render the chemical irritant harmless

render为＂使得＂的意思(后接受词+受词补语 )

chemical irritant->指dioxin(受词, O.)

harmless->受词补语(O.C.)

通常将O.C.移位时,受词前是不会加逗号的(因为老美懒惰),

但正式的话加逗号区隔会让读者看得比较清楚.

所以原句就是＂使得dioxin变得没有伤害性
