2015年Gmat語法試題及解析

2015年Gmat語法試題及解析

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

　　(B) trying that it metabolize, or render harmless, the 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后面不跟that從句

　　CD排除，attempt和try重復，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在這里是名詞)簡潔，化學刺激物

　　就比如在GMAT中我們有這樣一條公理 - n..that is (are) adj. 必然要換為adj.+ n.的名詞短語結(jié)構(gòu), 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，這個句子是不是怎么讀怎么不順，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

　　二惡英：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.

　　--- 這里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：將其還原后為：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"致使某物怎么樣了"。看到vt后面直接形容詞，就想到這個sth(the chemical irritant)可能因為長度太長被倒裝到后面了。

　　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，后面結(jié)構(gòu)是對enzymes的解釋。

　　有機體生產(chǎn)酶是有目的的(attempt在這里翻譯成目的)，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
