In many foods, the natural combination of vitamins with other nutrients makes those vitamins more usable by the body than are vitamins added in vitamin supplements.

than are vitamins added in....  比较结构中的are 是倒装么？为什么要倒装？
这里是什么和什么作比较？

the natural combination makes those vitamins more usable than are vitamins。。。
are这个不是倒装，是比较结构就是这样。

不解呀，为什么是are呀，are的主语是什么？

longee

the combination 把这些vitamin 搞的比那些vitamin更usable.所以是vitamin 比较vitamin，are 主语是后面那个vitamin

或者你yy 出来个简练的比较结构： those vitamins ARE more usable by the body than are vitamins added in vitamin supplements.

哦，所以这个句子的顺序可以写成：those vitamins ARE more usable by the body than vitamins added in vitamin supplements are.

这个句子，我是这么看的
1）句子主干The natural combination makes more usable than vitamins are added in vitamin supplements；
2）简单的结构为 A makes more usable than B；
3）The natural combination（A） 与vitamins in supplement（B）的对比；
4）are vitamin added是被动语态

这个句子的谓语已经确定了是实意动词makes，所以不应该是ARE；后面的are vitamins added只是一个被动结构。
