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
首先來用排除法做一下這道題
分析： 排除B，try後面不跟that從句
CD排除，attempt和try重複，犯了GMAT簡潔性原則的大忌
AE對比 the chemical that is irritating it不如the chemical irritant(irritant在這裡是名詞)簡潔，化學刺激物
就比如在GMAT中我們有這樣一條公理 - is (are) adj. 必然要換為adj.+ n.的名詞短語結構, 舉個例子： a girl who is nice 必然要換成a nice girl.
因此，此題選E
但重點來了，這個句子是不是怎麼讀怎麼不順，該如何理解呢?
讓我們來分步走：
第一步
先來一起解決一些生詞問題
二噁英：dioxin metabolize:新陳代謝 virtually:事實上，幾乎
第二步
補充省略部分
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.
--- 這裡的省略了動詞不定時中第二個to：to metabolize, or to render harmless the chemical irritant.
完整句：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 to render harmless, the chemical irritant.
第三步
看出that從句中the chemical irritant的共用
hat從句的理解：將其還原後為：that are the organism's attempt to metabolize (the chemical irritant), or to render harmless (the chemical irritant).
第四步
render倒裝句的理解
render是vt，正常語序為render sth. adj. 意為"致使某物怎麼樣了"。看到vt後面直接形容詞，就想到這個sth(the chemical irritant)可能因為長度太長被倒裝到後面了。
語序應該改為：or render the chemical irritant harmless.
第五步
解析that從句
that指代的enzymes，後面結構是對enzymes的解釋。
有機體生產酶是有目的'的(attempt在這裡翻譯成目的)，其目的是用來代謝化學刺激物，或者使這種化學刺激物無害。
第六步
整句完整翻譯
在幾乎任何動物物種的各種組織裡，二噁英都會刺激生成酶，有機體生產酶是有目的的，其目的是用來代謝化學刺激物，或者使這種化學刺激物無害。
