明白了，谢谢三楼这么精彩的解释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.
请问定语从句中的that指代什么？是指dioxin还是指enzymes?如果是指enzymes, enzymes 也不和organism's trying to metabolize, or render harmless对等呀？多谢指教！
难怪我看了半天没看明白，还想自己这第一遍SC真是白看了。MM贴的是原句，而不是正确的句子……
原题是 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（E）
正确答案是E。我认为that指代其前的名词enzymes，enzymes和attempt对等，attempt后面的to do结构表目的。我也刚刚开始看，不知道说的是否正确。而且照我这样解释，同样存在一个疑问，即为什么用attempt而不是attempts（毕竟前面enzymes和are都是复数）？这个小问题以前有人也问过，但好像没有有说服力的结论，搭楼主帖子的便车问一下吧
attempt表示是所有tissue组织中的enzymes所共有的性质，是整体用单数。OG和大全中都有例子：
1. Neanderthals had a vocal tract that resembled those of the apes and so were probably without language, a shortcoming that may explain why they were supplanted by our own species.
(A) Neanderthals had a vocal tract that resembled those of the apes
(B) Neanderthals had a vocal tract resembling an ape’s
(C) The vocal tracts of Neanderthals resembled an ape’s
(D) The Neanderthal’s vocal tracts resembled the apes’（B）
(E) The vocal tracts of the Neanderthals resembled those of the apes
The sentence requires a subject appropriate to both members of a compound predicate, the second member being and so were probably without language. B, the best choice, logically uses Neanderthals as the subject. Choice A also uses this subject, but the plural pronoun those does not agree with its singular antecedent, a vocal tract. C, D, and E present the inappropriate subject vocal tracts, which cannot logically govern the second member of the predicate (i.e., vocal tracts cannot be said to be without language). Moreover, it is better to use the singular in referring to an anatomical feature common to an entire species; C, D, and E use the plural vocal tracts. D compounds the problem by giving multiple vocal tracts to one Neanderthal.
Unlike other arachnids, which have their nerve cells evenly distributed along their bodies, the scorpion’s nerve cells are clustered in its head, like a mammal’s.
(A) bodies, the scorpion’s nerve cells are clustered in its head, like a mammal’s
(B) bodies, the scorpion’s head had a cluster of nerve cells, as a mammal does
(C) body, the scorpion has a cluster of nerve cells in its head, as a mammal does
(D) body, nerve cells are clustered in the scorpion’s head, like a mammal’s（C）
(E) body, a cluster of nerve cells is in the scorpion’s head, like a mammal’s
明白了，谢谢三楼这么精彩的解释
但是会不会attempt指的是production of enzymes?
请教attempt to metabolize, or render harmless, the chemical irritant中，是不是metabolize和render harmless平行？
the chemical irritant是啥意思？做啥成分？
但是会不会attempt指的是production of enzymes?
请教attempt to metabolize, or render harmless, the chemical irritant中，是不是metabolize和render harmless平行？

我觉得OG里一般的修饰成分都是紧紧跟在修饰词后边，不会修饰的很远，那样容易造成歧义。
看过NN的分析，metabolize是跟render平行，the chemical irritant做他们的宾语。
提另外一种解题思路，排除法1：
C,D不用说了，词义重复，先排除。
B,it, 的指代问题，
A,it，多余
E,所以正确
排除法2。
看答案，如果我们不知道这里要用trying or attempt, 假定用x代替
x to metabolize,...,the chemical irritant. 去代谢化学的刺激物。最佳答案。
推出，B,E 正确，另B啰嗦， 故只有E正确。

怎么ETS这样解释enzymes和attempt对等，是什么意思,语法对等,还是意思对等呢
