再请教

A leading figure in the Scottish enlightenment, Adam Smith’s two major books are to democratic capitalism what Marx’s Das Kapital is to socialism.

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
                   

请问这句话的结构使用？books are to noun +what+ book is to noun

这里的noun地用法很像动词，还是我理解错了？what是capitalism得什么成份？

哪位NN给分析一下这个句子的结构啊？

多谢多谢！

还是没看懂，没见过这种book are to + noun的结构，什么意思

"be to" is similar to "mean to"

mean to 后面可以加名词？

mean sth或者 mean to do sth

mean to + noun是什么意思，

you mean "refer to"

??

similar:

what A means a to B is what C means to D.

anyway,

urs" what a means to b is what c means to d"

here" books a& b are to m what c is to n"

totally different, I think.

in qn, what does this " what" mean; only 1 what here

I have not asserted that my example is directly applied to this problem.

anyway, I have no intention to entangle myself in this problem. If it were me, I would choose E.

D lacks something after "similar to" A,B,C, subjects should be people.

简化一下为

... that are to B what C is to D
