请教GWD中几道比较迷惑的语法题

sudashui

是一位学姐给的复习资料，只知道是GWD中的某一套，但是不知道是具体的哪一套。所以没办法查答案讨论帖了。

我比较菜，看了答案仍然不太明白，请各位路过的留下宝贵意见！

Q17:

Unlike most other mergers in the utility industry, which have been driven by the need to save money and extend companies’ service areas, the merger of the nation’s leading gas and electric company is intended to create a huge marketing network for the utilities in question with states opening their utility markets to competition.

 

1. and  electric company is intended to create a huge marketing network for the utilities in question with states opening

2. and electric companies are intended to create a huge network for marketing the utilities in question as states open

3. and electric companies are intended to create a huge network that will be marketing the utilities in question, with states opening

4. company and electric company are intending to create a huge marketing network for the utilities in question, with states opening

5. company and leading electric company is intended to create a huge network for marketing the utilities in question as states open

答案是E，我选的A。首先由主语merger可知谓语用单数，排除BCD,但是我觉得E对原文的意思改动较大，就没选。

我的疑问是，E选项的as引导的是时间状语从句吗？为什么E比较好呢？

下一道：

Q20:Approved April 24,1800, the act of Congress that made provision for the removal of the government of the United States to the new federal city, Washinton, D,C, also estabilished the Library of Congress.

正选E.Approved April 24,1800, the act of Congress made provision for the removal of the government of the United States to the new federal city, Washinton D.C., also establishing

（其他选项均有比较严重的漏洞，在此不列出了）我徘徊在保持原句与E之间，我认为主要就取决于made provision和establish这两个动作谁主谁次的关系吧，为什么选E呢？是因为原句头重脚轻吗？

Q28：Some scientists contend that many species of dinosaur had a metabolism more like a warm-blooded mammal's than a cold-blooded reptile's.

正选A.that many species of dinosaur had a metabolism more like

B.that the metabolism of many dinosaur species were more like

为什么选A不选B？虽然我知道the metabolism不能跟复数谓语were,但我觉得many species of dinosaur后跟a metabolism也很怪呀。在什么情况下复数主语可以跟单数宾语呢？

Q34. In an attempt to guarantee the security of its innovative water purification method, the company required each employee to sign a confidentiality agreement prohibiting that its water purification methods be disclosed to companies using an analogous purification process.

A.prohibiting that its water purification methods be disclosed to companies

B.prohibiting them from the disclosing of its water purificaiton methoeds to any company

C.prohibiting disclosure of its water purification methods to any company

D.that would prohibit them from disclosure of its water purification methods to companies

E.that would prohibit its water purification methods to be disclosed to a company

答案为E。BD中them指代不对，C中抽象名词disclosure不对，A错在哪儿？是因为prohibite后面不能跟从句，还是因为using an process（单数）不能修饰companies(复数)？

手都打酸了...

Q34. prohibit that搭配错  prohibit sb.from doing sth./prohibit sth.
