(A) scientistslearned how to make a synthetic growth hormone, removing it painstakingly (B) scientistshad learned about making a synthetic growth hormone, they had to remove itpainstakingly (C) scientistslearned how to synthesize the growth hormone, it had to be painstakinglyremoved (D) learning howto make a synthetic growth hormone, scientists had to remove it painstakingly (E) learning howto synthesize the growth hormone, it had to be painstakingly removed by scientists 答案是c，解释说a项指代错误，it指代应该是growth hormone,而不是 synthetic growth hormone, 它怎么知道是应该合成生长荷尔蒙，而不是制造一个合成的生长荷尔蒙？按照逻辑的话我觉的2个都可以，但为什么解释说后者不对呢？而且原文就用的A项的，不是要尊重原文的逻辑意思吗？作者: JIERONG1019 时间: 2011-6-7 10:37
如果选择A的话,整个句子没有主句也没有动词,不是一个完整的句子. 第一步:动词synthesize优于形容词synthetic,排除ABD 第二步:判断动词和逻辑主语 E中learning的逻辑主语是It,但是如果使用代词,所指代的名词必须出现过,这里是找不到的. 所以最终答案选择C吧 不知道这样理解对不对,你再想想吧作者: Emma90 时间: 2011-6-7 10:55
A的最大原因是句子不完整，应该首先排除 楼上说的根据动词优于形容词就排除ABD是不合理的，因为它们不是绝对错误 我认为DE是使句子意思偏离才排除的 对比BC明显C的结构更优从而选C
