标题: 885题中的两道语法题。
11-24

Just as plant species native to regions with browsing mammals evolved many natural anti-browser defenses (such as sharp spines and toxic chemicals), so humans in malarial regions have evolved dozens of chemical defenses against malaria.

(A) so humans in malarial regions have evolved dozens of chemical defenses against malaria
(B) humans in malarial regions have been evolving dozens of chemical defenses against malaria
(C) there has been, in malarial regions, an evolution of dozens of human chemical defenses against malaria
(D) dozens of chemical defenses against malaria have been evolved by humans in malarial regions
(E) similarly, in malarial regions, humans have evolved dozens of chemical defenses against malaria

答案是A。A前有so也对吗？而且必须用so？为啥？

Although it claims to delve into political issues, television can be superficial such as when each of the three major networks broadcast exactly the same statement from a political candidate.

(A) superficial such as when each of the three major networks
(B) superficial, as can sometimes occur if all of the three major networks
(C) superficial if the three major networks all
(D) superficial whenever each of the three major networks
(E) superficial, as when the three major networks each

答案是E，C错在哪里？
哪位高人解释一下as when从句的用法？还有plural n each后面的谓词动词应不应该用加S？

谢谢

(1)固定搭配,没有为什么just as ....so....

(2)as when这种用法前前面的帖子说了很多次了,你自己找找.C答案主要是逻辑意思的合理性,这个句子的意思是在强调个体,而不是整体.你仔细体会一下这两个句子的区别;
(1) the three major networks all broadcast exactly the same statement from a political candidate.
(2) the three major networks each broadcast exactly the same statement from a political candidate.

多谢斑竹赐教！

不好意思，再问一下：

each of the three major networks broadcasts 和the three major networks each broadcasts 两种形式都正确吗？

题目中的broadcast是表示现在时还是过去时？前面是can be,似乎是现在时啊，那就是说each放在后面时动词就不表示单数了？谢谢。

单数名词+each后面加动词复数

明白了，谢谢。

以下是引用1stzhang在2003-10-9 15:51:00的发言：
单数名词+each后面加动词复数

纠正：“n./pron.+each”做主语时，谓语动词的形式与each之前名词的形式保持一致，不受each影响。

C答案主要是逻辑意思的合理性,这个句子的意思是在强调个体,而不是整体???
sorry, i don't think this is the reason. the problem should be with IF

excuse me? is 'just as ... so...' a fixed phrase? what does it mean? thanks

11-19

When you say "although" , you mean you already know something the networks are all doing, so you wouldn't say "if". A and E are different cuz grammatically, the phrase " such as" can only be followed by a noun or noun phrase but here it's an averbial clause "when each..." so A is impossible. the answer is exactly E.

c e 之间的差别我认为最主要还是壮语成分的差别。 if 引导的是条件壮语，when 引导的是时间壮语。一个表示可能性，一个更多的加入事实成分。

要说each.....the same 和 all ....the same 实际上后者反倒更加常用或好一点，不过都是小差别
