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.
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.
A. By the same techniques used for genetically enhancing plants, making them B. With the same techniques to genetically enhance plants, so that they are C. Employing the same techniques used to genetically enhance plants so that they are D. Employing the same techniques to genetically enhance plants, which makes them E. Employing the same techniques for genetically enhancing plants that make them 这个题是选C 我选了D。。。。。。。A的Making错误太明显了,D中的主谓一致也很致命。我想问的是BC中they的指代问题!!!! 难道大家没有觉得这里的they有指代ResearcherS的可能吗?应该优先指代主句主语吗?这里很疑惑? 个人目前在北美,现在是晚上了已经。不知有没有勤奋的孩纸现在一大早在线啊?求解答
413 In the mid-1920’s the Hawthorne Works of the Western Electric Company was the scene of an intensive series of experiments that would investigate changes in working conditions as to their effects on workers’ performance. (A) That would investigate changes in working conditions as to their effects on workers’ performance
(B) Investigating the effects that changes in working conditions would have on workers’ performance
(C) for investigating what are the effects in workers’ performance that changes in working conditions would cause
(D) that investigated changes in working conditions’ effects on workers’ performance(B)
(E) to investigate what the effects changes in working conditions would have on workers’ performance 从我自己的个人理解,that一般是不做跳跃修饰的,做跳跃修饰的时候往往是修饰前面一个意群(即最近的一组意群)中的中心词,并且每当这个时候作者会尽量安排这个中心词后面的其他名词性单词以不同的单复数形式出现以避免歧义。
很抽象,拿你这道题来举例:that前面的意群是scene of an intensive series of experiments Investigating the effects ,因为修饰限定scene的部分“of an intensive series of experiments Investigating the effects ” 过长,很难把它提到scene的前面去,所以没有办法that只能在这个意群结束以后出现,但是为了让that 没有歧义,作者把所有的series,experiments, effects都安排成了复数,可以让exchanges的出现清楚地界定that的修饰对象为最近的一个单数名词scene。
可是每个选项里都有they或者them呀,还是靠逻辑意思了,researchers are disease- or pest-resistant 不太合乎逻辑吧,techniques 也不太合乎逻辑吧。而且they 离plants 也不远。优先指代但不是绝对!绝对的只有两条:代词的单复数和性别要和所指代的名词相符。
