请教og的解释 第18题

anzhang6815

 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

og的解释第一句说The structure of the first main clause and the comma following reliable lead the reader to expect a second main clause.我想问为什么看到reliable 和逗号就知道后面还要有main clause，最近在研究答案，发现og每句话都值得推敲，但是这句我怎么也没弄明白。请牛人帮忙！

怎么没人理我，大家不要不重视og啊。。。

自己顶一下

这个是OG 18么  我的对不上啊？

看到reliable就知道这个句子要结束了，因为reliable前面有个and 标志着前面三个形容词平行结构即将结束， 而,and 也是第二个平行句子的开始啊

大家都很重视OG  就是潜水的人太多了  呵呵

明白了，呵呵，就是and reliable又是逗号，所以后面肯定是另外一个main clause

这个是第11版og的第18题，刚才查了一下没错
