杀鸡倒计时啦，又是GED30的题，GWD30-17

cloudymind

D,E 里的 that/which以及 them 都很 ambiguous. C 里的指代非常清晰。我倾向于选 C

Employing the same techniques (that are) used to genetically enhance plants so that they are disease- or pest-resistant

17. GWD30-Q17:

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.

 

 

1. By the same techniques used for genetically enhancing plants, making them
           
2. With the same techniques to genetically enhance plants, so that they are
           
3. Employing the same techniques used to genetically enhance plants so that they are
           
4. Employing the same techniques to genetically enhance plants, which makes them
           
5. Employing the same techniques for genetically enhancing plants that make them

  我觉得E的问题是：that从句如果修饰techniques，那么them指什么呢；如果就近修饰plants显然不通,比较之下，我还是觉得C是最佳

查到原句：But researchers have been working on bolstering the protein quotient of plants, using the same techniques that genetically enhance plants to make them disease- or pest-resistant.
Jesse Jaynes and Kenneth Derrick have won a patent for a process that increases the protein in potatoes, sweet potatoes and tobacco.
the same … that，感觉E是对的
B和C还有不好的就是把so that这种不是修饰的明显是短句放在一个短语引起的短句内，这个好像很不妥，记得OG好像有这样的例子
还有原句是用的using，如果换到句子里，就是using technology used to.就能明显看出C是重复的

GOOGLE上查的，老外做的，感觉不错A & B are out. Starting the sentence with 'employing..' gives the right modifier for the researchers. D is out: 'which' seems to refer to plants. its logical precedent should be the techniques.

E has two problems i guess
- meaning is not clear. you are not applying the 'same techinques for enhancing plants', you are actually 'applying the techniques used to enhance plants in some other field now'. Try reading it again. The meaning changes in E.
- read this 'genetically enhancing plants that make them crop resistant'. It seems to say that the plants make themselves crop resistant. 'that' should refer to 'techniques'

My answer: C

还是同意 C

used 这里是过去分词做定语修饰 techniques，和 employing 不重复。

so that they... 前的逗号去掉明确 they 指代 plants，无歧义。enhance plants so that they 的结构清楚表达 因为技术强化了植物，使植物抗病抗虫 的意思，而避免了 techniques...plants that make them 中定语从句表达的歧义。

而且 the same A that... 结构中 A 应该是一个简单的名词，后面直接跟定语从句 that。如果 A 的成分过于复杂，that 从句的修饰就有歧义了

觉得意思是重复的

大致汉语就是：使用了一个技术用来blahblah
