Computers are becoming faster,
more powerful, and more reliable, and so too are modems, they are the devices
to allowtwo 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 devices to
allow

答案选B我知道，我想问一下C错在哪？ OG的解释是这里一定需要are,为何呢？

因为是两个动作相比较。是C和M的becoming在进行比较，所以需要are。如果没有are，就变成了C和M两个东西在比较，不符合语意。

而且沒有are的話modems沒辦法和前面的主句並列

edmundshi

我就是想知道为什么没有are就不能并列了

parallelism我知道～

关键是are为何不能省？省了为何不并列了？这里省掉并没有产生歧义啊～

B: Computers are becoming faster, more powerful, and more reliable, and so too modems
Computers are becoming [adj], [adj], and [adj], and so too modems.
"and"明顯的是要2個主句並列.
B造成1個主句和1個名詞並列.

因为是倒装，modems are so too.是跟前句话并列的。后面的那个是the devices 是修饰 modems的。

edmundshi

so too modems为何不能看成是so too are modems的省略呢？

so too modems是一个名词结构？

edmundshi

省略了are

还原成陈述句子形式：modems so too,为何不可以呢？

XDJM们原谅我钻牛角尖哈～

就是想把它弄清、弄懂

前一个be是助动词，后面的be是系表结构, 所以不能省略
