大全987-216

1.       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（B）

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

How can 'so too' be use.  Isn't it redundant?    ie.  'so are modems' seems correct.  or 'and modems too'.

216, sec14-18

A) so too are modems, they are the devices两个句子少连词。
B) best.这里, and表明后面跟着是句子，不能省are。the 用特指that更好。

C) 少are会产生歧义：Computers are modems.
D) 两个句子少连词。
E) 歧义：Computers are modems.

大全的解释.另外白永的书里也有讲.你可以看看.
