23. (25773-!-item-!-188;#058&002128)

While they remove carbon dioxide from the air, conserve soil and water, and house thousands

of species, forests also supply potentially valuable pharmaceuticals, and, as sources of building

material and firewood, that provide employment for millions worldwide.

(A) pharmaceuticals, and, as sources of building material and firewood, that provide

(B) pharmaceuticals, and sources of building material and firewood, are providers of

(C) pharmaceuticals and, as sources of building material and firewood that are providing

(D) pharmaceuticals and sources of building material and firewood, for providing

(E) pharmaceuticals and, as sources of building material and firewood, provide

考点: 平行对称（Parallelism）逻辑表达（Logcial Predicaton）

1) 平行结构

2) 句子结构

(A) and that结构没有平行对象

(B) 去掉as后,后半句变为forest also supply… , and sources… are providers…意思变为:森林也

提供了有潜在价值的药材,并且建筑材料和柴火的来源成为了全球上百万岗位的提供者. 改变了原

句意思

(C) and, as sources of building…结构没有动词,跟also supply不平行

(D) 语法上sources of…和pharmaceuticals并列,改变了原句的意思

(E) 正确, forsts also supply…and provide…结构平行

我审题的思路是因为平行结构是XXX，XXX and XXX，只能出现一个and。所以 pharmaceuticals后面的and如要出现，必须不能以正常的方式出现，则排除B、D。选项A错在逗号后面不能跟that，剩下的E比C更简洁。因为原题给出的答案解释和我的思路没有关联，请各位NN解答一下看我是否碰巧撞对的。

10. (25025-!-item-!-188;#058&001699

Ancient hunter-gatherers developed instincts that stigmatized selfishness, and voluntary cooperation was encouraged as well, whether it be within the group or also with outsiders.

(A) selfishness, and voluntary cooperation was encouraged as well, whether it be within the

group or

(B) selfishness, encouraging voluntary cooperation as well, both within the group but

(C) selfishness and also encouraging voluntary cooperation, within the group and

(D) selfishness and they encouraged voluntary cooperation, whether it be within the group or

(E) selfishness and encouraged voluntary cooperation, not only within the group but

考点: 平行对称（Parallelism）、简洁有效（Rhetorical Construction）、指代一致（Agreement）1) not only…but also…连接的对象一定要平行2) 主动语态优于被动语态

3) 并列句主语相同,应该省略重复的主语.

(A) 使用被动语态(was encouraged…),增加句子的复杂性;whether开头的结构笨拙复杂,且it没有

可以指代的对象.

(B) –ing结构encouraging…作为stigmatized selfness的伴随成分,而从句子的逻辑意思上看,该成分应该跟stigmatized并列;both…but also结构不符合习惯用法.应该改为not only…but also或者both…and结构(C) also encouraging和stigmatized不平行(D) 并列句主句相同,they应该省略;如果一定要用they的话,and前面必须用逗号隔开,构成一个新

的句子;whether…or also结构笨拙复杂,且it没有可以指代的对象

(E) 正确, encouraged同developed构成并列谓语;not only…but also符合习惯用法

题目解释A和D中说it没有指代对象，但是我觉得it 指代的是voluntary cooperation ，这是为什么？

前面的是from a, c and w, and h,是个从句，两个and 是因为一个平行里包含另一个平行，比如小兰，小红和她老公，和小利
后面的是主句froest supply...and, as...,provide其实就是do and do,但有个插入语，所以成了do and, 插入语，do

第十题更简单，A和D的whether or 应该改为either or, B和C应该是both and ,所以只剩E了 not only ... but also
而且其他选项的or或and 都接不了also

谢谢candicelu的解释，路漫漫其修远兮，继续看prep的语法

其实我的水平也不高，我现在也在准备二战，这种都是熟练工种，建议你还是多看有解释的，比如OG，看多了你就知道出题点了，感觉你好像还在初级阶段，上面两题都是比较典型的题，一个是平行一个固定搭配，多看看OG的解释吧
