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

Although an "-ing" verb such as trying can sometimes be used as a noun, the phrase the organism's trying to metabolize in A is unidiomatic because trying is used as the object of organism's. In B, trying that it metabolize is ungrammatical. The noun attempt could follow organism's; also, it would parallel the noun enzymes, and parallelism is needed here because the sentence uses the linking verb are to equate enzymes and attempt.

上面为什么不用attempts,而用attempt,这样单复数就不一致了呀?毕竟前面是enzymes和are, 而后面却是attempt呀.请教NN!

主语和宾语之间没有什么绝对的单复数一致的关系。比如：

They are cowboys.
We are a team.

可是that引导的从句是修饰enzyme的呀,总不能说attempt是enzyme吧.另外也不能说he is cowboys呀? 还是不太明白,至少我认为主语如果是单数,宾语应该不能是复数吧.继续请教NN!

呵呵，我不是NN

我也说说我的理解

在这个that 从句中，that-是修饰enzymes没错，所以从句中用are;

doxin这种化学物质导致了酶的产生是的意图是为了新陈代谢（分解）这种化学物质，这里说的一种意图，所以应该用单数形式

不知这样说对否

偶也是刚刚开始复习

的确不可以说he is cowboys, 但是这里that指代的是复数enzymes. 所以这里的问题是“主语是复数，宾语可以是单数”，而不是"主语如果是单数,宾语应该不能是复数".

主语和宾语的单复数没有必然的联系

再举一个例子

17.   Native American burial sites dating back 5,000 years indicate that the residents of Maine at that time were part of a widespread culture of Algonquian-speaking people.

这样的情况多发生在另一个名词是抽象名词 如culture, attempt 时

如果名词是具体名词 在一般情况下要求单复数对应

这道题可以迅速用排除法来做的，1 优于定律：抽象名词优于动名词，所以要用attempt不用trying；2 CD里attempt to try语意重复，排除。只剩E是正确的。

建议James兄弟注意主考点就好了，OG的SC每一题都有明显的主要的考点，根据这些考点很快就可以把题做出来。ETS绝对不会单考某一个小小的单复数的考点，并且将这个考点作为主要解题依据的。偶们是为了拿分而复习的，这些小细节放过吧。

P.S.我总结下来，考单复数的题无非两种考法：1 主谓搭配 2 指代。本题两者皆不是，不要太在意。

谢谢XYMM的指点!!我们的情况很相似哦,都是干的不爽想辞职但是被老板说服边上班边复习. +U!

看讨论真好，终于明白了the chemical irritant 的成分，原来以为它是下一句话的主语
