讨论 GWD21-Q1 、 GWD18-Q11

alanzr

原题如下：1. GWD21-Q1:
According to analysts, an alliance between three majorpersonal computer companies and most of the nation’s largest local telephonecompanies would enable customers to receive Internet data over regulartelephone 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
   
5. at     speeds much higher than are
   

答案是E， 我选的D, 感觉E中有 are 很怪
------------------------------------------------------------------------------------------------------------
2. GWD-18-Q11In no other historical sighting did Halley’s comet causesuch a worldwide sensation as did its return in 1910-1911.

1. did     its return in 1910-1911
   
2. had     its 1910-1911 return
   
3. in its     return of 1910-1911
   
4. its     return of 1910-1911 did
   
5. its     return in 1910-1911
   

答案是A,我选的是E, A中的 did 为什么要有呢？


谢谢！

at speeds (that are) much higher than (they) are currently possible
that are 在定语从句中最好省略掉，
有一点是一定正确的但是我不知道该怎样拿出reference来证实，就当我是在实践中总结的吧
adj+more+n1.....than 后面一定不能再加与n1相似或指代n1 的词，

对于“that are 在定语从句中最好省略掉”有点犯迷糊，why省略掉？关于定语从句中that的省略，只有说法是that如果在定语从句中做宾语，则that必须省。但此题中，that是做主语啊，怎么能省呢？

我发现我在CD上找的答案有点问题，询问大家哪能下载到 Gigi 13套较权威的答案呢？ 谢谢诸位了！！


另外CD 22套的答案我也下载的是旧版本的，请问谁有经讨论验证过的较权威的版本呢？

speeds much higher than speeds currently possible
主语speeds相同，省略
B肯定不对，只少也是those，虽然those也不对我觉得
（话说得好找抽）

H caused such a worldwide sensation in no other historical sightings as in its return in 1920.

In no other historical sighting did Halley’s comet causesuch a worldwide sensation as did its return in 1910-1911.

A.  did its return in 1910-1911

A的错误，”彗星“ 和 ”它的归来“ 是不能相比较的

第一题中than后面实际上是speeds are currently possible，省略了speeds。如果选D，that currently possible是错误的语法表达，就算that 指代的是speeds, 也没有speeds possible的表达，缺少了BE动词。另外，speeds more higher than的表达比more higher speeds的 表达要有效清楚，形容词的比较级和than紧挨在一起。
第二题答案是C，in its return和前面的in no other historical sighting 对应。A中补出的did和谓语cause对称逻辑上是错误的。
拙见仅供参考，求高人指点。

第2题是og题，答案选c in its return 是正确答案
