1.By the same techniques used for genetically enhancing plants, making them disease- or pest-resistant, researchers have been able to increase the amount of protein in potatoes, sweet potatoes, and tobacco.

C Employing the same techniques used to genetically enhance plants so that they are

E Employing the same techniques for genetically enhancing plants that make them

C的代词会不会产生误解？ E错在哪里？

2. Researchers agreed that the study of new treatments for heart attack patients was extremely important but more research was needed to determine that balloon angioplasty preceded with ultrasound was or was not any better for heart attack patients than the balloon procedure by itself.

Bmore research was needed for determining whether or not balloon angioplasty preceded by ultrasound is any better for heart attack patients than is

Cthat more research was needed to determine whether balloon angioplasty preceded by ultrasound is any better for heart attack patients than

争议题，两个选项到底哪个好？

3. 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.

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

A选项with逻辑意思不对，为什么？

1 c的THEY指代不清楚，E也是啊，that代technique和plant哪一个呢？
3题同问

aeoluseros · 发表于 2010-12-25 13:21:47

1.C。E里面for doing sth.和that都是修饰techniques，比较C,E意思：E指"研究员使用"增强植物基因并能增强植物抗病性的技术"来增加蛋白质"。C指"使用增强植物基因的技术来增加蛋白质（进而能提高植物抗病性）"。
E表达的含义会让人感觉不够清晰，既然是用来增加抗病性的技术为什么能增加蛋白质呢？
C的表达就明确多了，抗病性只是增强基因的效用之一，而增加蛋白质是另一个效用。
相比之下C更好。

umm...关于代词they的指代，我是这么想的不知道大家的意见如何。作为这个句子读者，基本上90%都会认为disease- or pest-resistant的主语是plant，即便有10%认为有歧义，但是这点小纰漏还是没有上面提到的“意思含糊”的错误大。两权想害取其轻，就把E排除了。而且如果非说C里面的指代有问题，那么E里面的that能不能跳跃指代到techniques也是问题（正如Eileenl所说），两者相消，剩下E的那点不好。umm...我承认我的思路很杂。

2.C，prep08里面有这道题。"B. but后应补出that平行；whether or not累赘，直接用whether即可；仅仅是主语的比较，be动词is应该省略，省略is不会产生heart attack patients与the balloon procedure比较的歧义，如果两者要比较则必须后者也要补出介词for；need for doing不如need to do明确动作趋向。

3.A的意思是"这场兼并与开放公用事业市场的州一同来create a huge marketing network"。如果换用独立主格（with前加逗号）会好一点，但歧义仍在，用as引导的伴随状语就更没问题。所以应该改成as states open...

aeoluseros ，谢谢你
昨天晚上发的时候就想写上希望你帮答一下，结果真答了，感谢

第二题，我个人觉得but that的话，意思有点问题，前面的谓语是agree, 前后两个句子翻译过来就是：同意....同意但是......逻辑上说不通

所以其实两个选项都有些问题

aeoluseros · 发表于 2010-12-25 23:33:42

莫非这就是传说中的念力，不过这几个问题很赞:-D
umm...可不可以这样想: 研究员们同意新技术很重要，但是同意还需要进一步研究某某某。即Researchers agree that ... but (agree) that...

mudiduange · 发表于 2010-12-25 23:47:56

agree在that之前哦，所以应该是同意但是....反正语义上有些问题。相比较for, whether or not,还有省略is的问题，我觉得这个问题要大点：）

aeoluseros · 发表于 2010-12-26 00:10:42

umm...Researchers agree that ... but (agree) that...but在agree前，为什么是“同意但是”呢?

mudiduange · 发表于 2010-12-26 00:17:51

but如果在agree前，后面第二句子就有问题了
sb but agree that这个句子有问题呀，在谓语动词前方个连词

sdcar2010 · 发表于 2010-12-26 00:56:04

"But" is OK. It simply indicates a transition/contrast in researcher's opinion. It is akin to: The researchers agree that although the new treatment is important, more work needs to be done. The first part is a concession and the second part is a suggestion. It is logically and grammatically sound.
