请教GWD和prep上的两个问题

媛子大人

1. GWD21-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.

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（E）

问题1、补出原句后再省略和答案不一样：
    有NN说，E的原句是：at speeds (that are) much higher than speeds that are currently possible。我觉得第一个that are后面都是speeds的定从，第二个that are是第二个speeds的定语，两个都可省，即at speeds much higher than speeds currently possible。然后speeds又一样，省略，结果就是at speeds much higher than currently possible，但E中多了个are。不太明白这是为什么，是我省略有问题么？想请教下大家
问题2、 D选项中at much higher speeds 和E中at speeds much higher than 有差别么？能不能补出原句让我看下？谢谢大家！

OG251. The gyrfalcon, an Arctic bird of prey, has survived a close brush with extinction; its numbers are now five times greater than when the use of DDT was sharply restricted in the early 1970's. .

A.extinction; its numbers are now five times greater than

B.extinction; its numbers are now five times more than

C.extinction, their numbers now fivefold what they were

D.extinction, now with fivefold the numbers they had（A）

E.extinction, now with numbers five times greater than

请问E中这个with做的是伴随状语吗？因为解析说 the phrase confusingly seems to parallel with extinction我就不明白了，什么是parallel... 还有now的用法正确么？本来now是和when..做比较的，现在提到句首来我觉得从句意上理解仍旧是比较哇~

以上就是偶的问题～提前谢过大家啦～Y(^_^)Y

第一个题目好阴险，我昨天也做错了，今天恰巧在总结
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 at speeds much higher than are currently possible.
这个里面是speeds的比较:an alliance...would enable customers to receive ...at speeds much higher than are currently possible.
--> an alliance...would enable customers to receive ...at speeds much higher than [speeds( that are) currently possible].
省略了speeds that,只保留了are
我认为，这里的much higher than...都是用来修饰speeds这个名词的，所以不存在有些人说的是与customer的比较
被省略的speeds that里面，that是作为定语从句修饰speeds

D选项，不能用that指代复数名词speeds

类似的，prices are higher than we expected.
--> prices are higher than (prices that) we expected
省略了prices that，直接保留后面的动词

这个结构我们之所以会觉得奇怪，是因为真的很少见

第二个题，前面有has survived a close brush with extinction，如果后面再出现with结构，很像是与with extinction并列
now的用法没问题，时间状语，与when形成比较

问题太多，先讨论第一个问题。

我觉得如果按LZ说的省略的话，前面speeds 后的应该是 would be much higher. 后面才是are. 所以than 后面are 不能省略，强调时态不同。

同学你说的很在理诶，因为时态不同这个are不能省。但是照理说，前面补出后，speeds that would be much higher..这里也不能省略啊

二楼的同学给了个例子：
类似的，prices are higher than we expected.
--> prices are higher than (prices that) we expected
省略了prices that，直接保留后面的动词

为啥他省略前面保留后面啊？

我看到了你的总结，很棒！
我同意“much higher than...都是用来修饰speeds这个名词的”，不过楼下的同学又提出了关于省略的新看法，有空一起看一看哈~

媛子大人

kiwifoodtown同学~我又仔细想了想，我觉得第一个at speeds,这里不是would be much higher。
因为，at speeds that would be much higher，意思是“在这样一个速度下，这个速度在将来会比现在的速度快”
不管是多快的速度，即便现在无法达到，但是不论什么时候，用数字都是可以衡量，即可比较的。“速度 ”这个概念本身没有未来、现在之分。
所以，速度的比较都应该用一般现在时。
我不知道我说没说明白。。。。T^T

我认真把Mia的总结贴读了一遍，发现这句话，和我们讨论的差不多：
A large rise in the number of housing starts in the coming year should boost new construction dollars by several billion dollars, making the construction industry’s economic health much more robust than (it was) five years ago.

[it was]不能省略，因为than前面没有相应的状语结构


只不过这句话里保留了it，GWD那道省略了speeds。。

想了一下，at speeds (that are) much higher than speeds that are currently possible。应该是正确的还原。
在时态，谓语都一致的情况下，省略掉重复，但又保留基本语义后，就是E了，are 不能省，省略后比较结构的前后都会缺少主要成分可能会引起歧义。

MiaZhang

at speeds much higher than are currently possible
speeds后面没有必要再出现would了，因为前面有would enable cutomers...已经表示将来的时态了

我觉得DE的now的位置也有点问题。。。。
