Books are our best friends as people often say.这个句子里,已经有一个as了,再添一个as

问题描述:

Books are our best friends as people often say.这个句子里,已经有一个as了,再添一个as
要构成as.as的形式,如果不可以,为什么?

可以.Books are our friends as good as XXX.
不可以.这里的as 从句可以提到句首:As people often say,books are our best friends.
正如人们经常说的那样,书是我们最好的朋友.不是上面那个句型:书是我们的朋友,象.一样的好.
