[已解决]问一个关于whereas的语法点~~~

carvinhuang

今天看PREP的语法笔记~~~ 看到下面的一段话~~ 我完全蒙了~~ 哪位能给我解释一下呢~~？




(1) whereas = while（while前后句子之结构要求并列相对）

(2) whereas连接的平行比较只要求对比的核心逻辑上有对称关系，不要求对称位置必须是对称名词，下面句子中主从句的主语分别是energy和nuclear power并不是对称名词，但是对比的核心都是“核能发电占总产出能量的份额”：

如OG12-131 Over 75 percent of the energy produced in France derives from nuclear power, whereas nuclear power accounts for just over 33 percent of the energy produced in Germany.

*：但是如果whereas后面接介词短语，那么主句的开头也必须需要是介词短语(whereas后出现介词短语或者状语都会非常对称)，如果whereas后接单纯主谓宾（或主系表），主句也要尽量用单纯的主谓宾（或主系表）来对应，除非同下面GWD 18-2一样后半句主谓即已经可完全表达出“对称”的含义：请问这句话是什么意思？

prep1-54 In cooking, small quantities of spices are used, whereas in medicinal usage spices are taken in large quantities in order to treat particular maladies.

prep2-102 Whereas a female grizzly bear in the Rockies typically occupies a range of 50 to 300 square miles, a male will cover 200 to 500 and occasionally as many as 600.

大全933.Whereas owners of condominium apartments have free and clear title to their dwellings, owners of cooperative apartments have shares in a corporation that owns a building and leases apartments to them.

GWD18-2According to findings derived from functional magnetic resonance imaging (MRI), the area of the brain in which a second or third language is stored depends on the age of the language learner; whereas each language occupies a distinct area of the brainin an adult learner, language areas overlapin a young child.

each language occupies a distinct area of the brain是主谓宾齐全；language areas overlap是主谓，没有宾语。但两个句子依然算是平行，因为逻辑已经平行。

哇~~ 原来是这样！明白啦~谢谢~！

我查了新牛津字典，whereas 的例句是  you treat the matter lightly, whereas I myself was never more serious.
前面是主谓宾后面是主系表，这个如何解释呢？？？？

求证 while 结构平行？？？  although反正是不要求的好像

应该说这三个只要逻辑上能够平行就可以把，至于结构平行应该是 effectiveness的问题。

20. GWD26-Q20
In 1981 children in the United States spent an average of slightly less than two and a half hours a week doing household chores; by 1997 they had spent nearly six hours a week.

A.    chores; by 1997 they had spent nearly six hours a week
B.    chores; by 1997 that figure had grown to nearly six hours a week
C.    chores, whereas nearly six hours a week were spent in 1997
D.    chores, compared with a figure of nearly six hours a week in 1997
E.    chores, that figure growing to nearly six hours a week in 1997

这句话不能选C有人给出解释说，whereas前面主动后面被动，所以错。 但又有人说是重心转到 six hours了所以错误 。

求NN们告诉我到底平不平行啊
