GWD21-Q1:

1r1r1r

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.



A.with speeds much higher than is

B.with speeds that are much higher than are

C.at much higher speeds as are

D.at much higher speeds than that

E.at speeds much higher than are
为什么选E，我选成C去了，E中的than后面补全是什么样子？are的补充从逻辑上是讲得同啦，可是之前一点迹象都没有，也不怎么对称

at speeds (which are) much higher than （which）are currently possible.
我理解E选项可以理解后置定语从句作为 SVO than SVO的比较。 省略了主语which，保留动词 are。
而如果是C、D的选项： 应该是宾语Speeds的比较 at much higher speeds than those currently possible.

不知道是不是这样理解。

请NN指正。

不知道说的对不对啊……试着解释一下……
整句简化下来应该是这样：
An alliance would enable (customers to receive internet data at speeds much higher than are currently) possible.

currently是副词，应该跟在动词或形容词后。所以D排除了
speeds 是复数，动词用are，排除A
C的问题是比较级后面跟as应该是确定的倍数或者是相等吧，这个不是很确定，等大牛解释~
D的句意有点问题，speed没有一个限定，没法比啊，可以说at much higher speeds next year than are currently（如果不对请批评指正），或者at speeds higher than （they） are currently。
E没什么问题

抛砖引玉~！

LS的简化好像不太合理吧？应该是 enable customer to receive... 吧？

意韵甜心

对~我括号里不是省略的意思，是突出enable sth possible

nemiah

我不觉得是enable sth possible的意思哦。。

我感觉也不是enable sth possible 不对啊
都enable 了， 就不用possible了吧
另外， 我觉着这里 currently 是在修饰possible
就是现在可能的

这道题， 做了n遍， 错了n遍， what a fucking question.
借这个帖子， 好好总结一下这道题

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.

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

疑问的关键在
speeds much higher than is currently possible   这个。。。我个比较
长的比较随心所欲， 奈何人家就是这么品味出众， 我等考生也只能忍着e心，迎头淡定，低头，溜过
可能我轻功不好， 屡溜，屡不过，结果弄到今天这个份上， 只能好好总结一下。

前面是一个名词后面显然是一句话， 因为有谓语
如果改成  
speeds that are much higher than speeds are currently possible
关键这个比较太球特殊了， 估计是中国古代建筑群中一个哥特式城堡吧

首先没有宾语， 这就是传说中的主语在比较吧
再次， 这个句子中出现了两个speeds， 怎么看都别扭
最后， 居然前后时态一样。你说，一颗树， 小时候， 和长大比较吧， 我能理解， 但是，我说这颗树现在长的比目前可能长的都高，
我就得转动我不太灵光的脑瓜，思索上半年，才能反应过来

说了这么多，就是一个  简洁有效
speeds much higher      用形容词替代  be + adj 从句是为了简洁
than 后面去掉  speeds 也是简洁，
个人感觉   speeds much higher than current possible  并不错， 可惜不在答案里

因为这个和
economy might
not be as weak as some analysts previously thought.
是一个道理。

个人观点， open discuss哈

LS的心态正好啊
