请教一个英语语法
The world’s three top central bankers (Greenspan,Duisenberg and Hayami) are all close to the top of the alphabet,even if one of them really uses Japanese characters.As are the world’s five richest men (Gates,Buffett,Allen,Ellison and Albrecht).
as 为什么可以用一个as作主语?

答案

答：类似于：So are you.你也是这样.的用法.主语其实在后面,是you.
意为：世界五大首富也是这样.（首字母很靠前,AABEG）,世界银行界三大巨头,其首字母都接近字母表之首：GDH（最后一个是日语名）
