TT GWD-21-1

Q1:

According to analysts, an alliance between three major personal computer companies and most of the nation’s largest local telephone companies would enable customers to receive Internet data over regular telephone lines with speeds much higher than is currently possible.

1. with speeds much higher than is
2. with speeds that are much higher than are
3. at much higher speeds as are
4. at much higher speeds than that(E)
5. at speeds much higher than are

这道题的e之后没有说明比较对象啊,这样也可以吗?

不太明白啊,好象不平行啊

Just pass by, and see my old response. haha..

E) at speeds much higher than (those) are

Those means the speeds of the data transmission currently.

Like I said on the second floor, whenever the subject of comparision is obvious enough, you don't have to repeat it.

同问同问 哪位大侠能还原以下 看着真得很别扭

at speeds much higher than(speeds) are possible?

顶一下,有人能解答吗???

为何要有are出现呢?? 前面的speeds 并未出现助动词呀??
