两条发疯的题目,希望帮助SOS!!

73

考点：

系表结构与动词结构可以平行，很颠覆吧。这题的平行是；

A is not ... but comprises ...

系别结构与动词结构平行，还有其它例子（我的笔记上没有抄原题，只记了浓缩结构）：

1) A is a relative of ... and resembles ...（Prep61）

2) A is not ... but consists of ...(Prep76)

many biological traits are not
            the products of natural selection

but are
                        by-products of other evolutionary developments.
                

这里是be not....but(be) 平行结构，加be 避免了but由连词变成介词（除了）的歧义
