4. The only way for growers to salvage frozen citrus is to process them quickly into juice concentrate before they rot when warmer weather returns.

(A)to process them quickly into juice concentrate before they rot when warmer weather returns

(B)if they are quickly processed into juice concen­trate before warmer weather returns to rot them

(C)           for them to be processed quickly into juice concentrate before the fruit rots when warmer weather returns

(D)           if the fruit is quickly processed into juice concen­trate before they rot when warmer weather returns

(E)to have it quickly processed into juice concentrate before warmer weather returns and rots the fruit

For parallelism, the linking verb is should link two infinitives: The only way to salvage... is to process（the way to…is to）. Choice A begins with an infinitive, but the plural pronouns them and they do not agree with the singular noun citrus. Choices B, C, and D do not begin with an infinitive, and all present pronoun errors: the plural pronouns cannot grammatically refer to citrus or fruit, nor can they refer to farmers without absurdity. The best choice, E, has parallel infinitives and uses fruit to refer unambiguously to citrus（如果用代词，可能会被理解为是juice concentrate，因此用the fruit好）. E also expresses the cause-and-effect relationship between the return of warmer weather and the rotting of the fruit; A, C, and D merely describe these events as contemporaneous.(还是逻辑意思问题)

E also expresses the cause-and-effect relationship between the return of warmer weather and the rotting of the fruit;

在并列中可以表示因果关系吗

并列表示的是单独的事情 表示先后前后顺序 或动作相反等等  伴随的动作才可以作为因果关系

不知OGE的这句话该如何解释

谢谢

E里面很准确地表达出了因果关系，bad weather rots the fruit. 分析一下主谓宾，就很清楚动作的发出者，承受者。

而A,C,D只表达出了时间关系，其结构是the fruit rots when the weather returns. 这个句子里我们只知道两者同时发生，但不知道有没有因果关系。

AWA里有个类似的逻辑错误，就是A is the cause of B, because A occurs before B. 具体到这道题，就是我们不能得出这样的结论: A is the cause of B, because A occurs when B occurs.

太感谢 明白了

偶有个疑问，为什么citrus在这里就一定是单数呢？

查了下辞典，citrus可以单复数同形的啊！

如果不管因果关系的错误，A中to process them quickly into juice concentrate 也应该没错吧！

看一下本贴, 可能有帮助.

谢谢mm！

可惜你的两个问题偶不是很清楚哦！

对这句解释不是很明白：For parallelism, the linking verb is should link two infinitives: The only way to salvage ... is to process.

OG84：

One legacy of Madison Avenue's recent campaign to appeal to people fifty years old and over is the realization that as a person ages. their concerns change as well.

(A)  the realization that as a person ages, their

(B)   the realization that as people age, their

(C)  to realize that when a person ages, his or her

(D)  to realize that when people age, their

(E) realizing that as people age, their

Choices C, D, and E can be faulted for failing to complete the construction One legacy ... is with a noun that matches the noun legacy; these choices use verb forms--the infinitive to realize or the present participle realizing--in place of a noun such as realization.

到底什么时候用to do，什么时候用n.？？

就是要对称的意思啊。前后都用不定式。。。

那OG84呢？为什么又用名词？

我本来是明白的，可是看到84又糊涂了

4是the way to do ... is to do ...

84是one legacy ... to do is n.
