28. 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
答案是E我知道，可是代回原句In virtually all types of tissue in every animal species, dioxin induces the production of enzymes that are the organism’s attempt to metabolize, or render harmless, the chemical irritant. 我看不懂这句话的意思，the chemical irritant这里做什么成分？然后that从句修饰enzyme的话，enzymes that are the organism’s attempt？感觉怪怪的
我是这样理解的：or render harmless, 是插入语，所以后面的irritant就自然是新成代谢掉的东西了。因为查了字典，metabolize是及物动词，后面一定要接宾语的。the chemical irritant就是它的宾语了。
然后，是 the production of enzymes that are the organism's attempt。意思是酶的生产其实是有机体在做一种尝试。什么尝试呢，就是去代谢掉（或无害的补偿）生物刺激物的尝试。
or render harmless的确是插入语，因为如果结构上两个动作是平行的话，那么or前面那个逗号就应该去掉：逗号不可以加在两个平行的动作之间的连词前面的；但是render和METABOLIZE的确逻辑上是平行的，猜测这里用插入语可能表示render这个动作确实存在，但是主要还是新陈代谢这个动作
