1. Adam Smith’s two major books are to democratic capitalism what

2. Adam Smith’s two major books are to democratic capitalism like

3. Adam Smith’s two major books are to democratic capitalism just as

4. Adam Smith wrote two major books that are to democratic capitalism similar to

5. Adam Smith wrote two major books that are to democratic capitalism what
               

A 和 E 之间有什么区别阿?

呵呵　这种结构初次看到往往都会感觉比较迷惑。

答案应该是Ｅ

Adam Smith’s two major books are to democratic capitalism what Marx’s Das Kapital is to socialism.

比较划线部分，这个结构是：A is to a what B is to b.就是：A对于a来说的意义，就相当于B对于b来说的意义一样。算是比较结构，只是层面相同。

但是在这种情况下，就和前面的a lead ...　不对了，也就是说，前面说的是人，后面成了书了。

如：A world-wide famous basket player, michael jordan (比较这里面如果加上's performance)　was wonderful on court.
