[求助]OG上的一道语法题

sunslover

Computers are becoming faster, more powerful, and more reliable, and so too are modems, they are the devices to allow two or more computers to share information over regular telephone lines.

(A) so too are modems, they are the devices to allow

(B) so too are modems, the devices that allow

(C) so too modems, the devices allowing

(D) also modems, they are the devices that allow

(E) also modems, which are the decices to allow

正确答案是（B），可是有''so too are......"的句型吗？ 一直以来都是"so are ......"的呀。

呵呵.So are句型就是一个强调SO的简单倒装结构.至于加不加TOO只是是否增加一个副词而已,根据意思判断就好了.
