with speeds much higher than is
with speeds that are much higher than are
at much higher speeds as are
at much higher speeds than that
at speeds much higher than are
题目分析：
本题主要考查考生对于比较中省略现象的理解。
选项分析：
选项A：由于speeds是复数名词，所以应该将本选项中最后一个be动词改为复数动词are。
选项B：至少，本选项应改为：
speeds that will be much higher than are currently possible
这是因为，速度应该是在未来更高，而不是现在更高。
选项C：习语有误，more + than为习惯表达，不能用more + as。
选项D：speeds是复数名词，不能用单数代词that指代。
选项E：Correct. 本选项在语法和逻辑上均是正确的。

d项
该选项的比较重心在动作上，而不是在speeds上，因此比较标志higher放在了介词短语at higher speeds里，而不是speeds的定语从句里，所以不能拿一个句子和that（speeds）相比，在d的基础上，可以有正确答案would enable customers to receive internet data over regular telephone lines at much higher speeds than the customer could do currently and possibly.
