In 1995 Richard Stallman, a well-known critic of the patent system, testified in Patent Office hearings that, to test the system, a colleague of his had managed to win a patent for one of Kirchhoff’s laws, an observation about electric current first made in 1845 and now included in virtually every textbook of elementary physics. (A) laws, an observation about electric current first made in 1845 and (B) laws, which was an observation about electric current first made in 1845 and it is (C) laws, namely, it was an observation about electric current first made in 1845 and (D) laws, an observation about electric current first made in 1845, it is (E) laws that was an observation about electric current, first made in 1845, and is b选项中Which 为何时代不明,was已经是单数了啊。e选项中that指代问题?还有用逗号隔开后为什么会有distort meanings 作者: starlitcream 时间: 2012-11-14 16:34

说说个人的理解吧
X of Y 的结构,同位语的话,两个都可以修饰,具体要看句意(参见OG13的19题) which和that,个人认为只能修饰Y(已经确认了,详见这个帖子:http://forum.chasedream.com/GMAT_SC/thread-441459-1-1.html)
再看句意,这里essential modifier vs. non-essential modifer很用药。that是essential modifier, which不是,两个逗号隔开的插入部分也不是。 看E选项,隔开了表示是non essential的,不是句子想表达的重点。但你读这句话,分明就想表达1845年怎样,现在又怎么样,所以1845不能被隔开。要作为essential modifer用。
OG的解释,个人觉得,关于语法部分,真的不怎么样,别人native speaker不会那么抠字眼的。但句意部分强调的非常明显,这就是为什么我们要强调句意。作者: starlitcream 时间: 2012-11-14 18:08
嗯 刚才看了一个人的解释 没有过分强调语法 是从句意下手的 谢谢了 我去看看which that 那个去作者: 洗头发的水 时间: 2013-8-8 20:14
LZ,这题本人愚见认为是这样的。
1.首先,对于E选项,先不考虑that指代那个K LAW合适不合适(从本人的角度上来说,我认为是合适的,因为一般来说,that除了不能够指代人以外指代其他的东西貌似没有特别严格的限制)。你注意下THAT后面的那个从句laws that was an observation about electriccurrent, first made in 1845, and is。其中first made in 1845是插入语,可以抹掉,那么that后面的句子就变成了that was an observation about electric current and is。这里的and很显然是一个平行结构的maker标记着后面的成份需要和前面的某些成份平行。
那么,是什么部分平行呢?仔细看下,我们发现是从句:即前面的那个that从句应该和后面的那个that从句平行。因此E的问题就出来了,两个从句在平行结构中的话,无论从句的引导词一不一样,都是不能省略的。那么就是说,E的问题出在and后面少了一个从句的引导词。
2.再看B这个WHICH从句。首先我可以很负责任的告诉你,which这里引导从句从语法上是没有问题的,which修饰前面那个名词也并没有什么指代不明的问题。B选项存在的问题,仅仅是一个和最佳答案对比的问题。因为B选项中,有which was和it is(在and后面)这样的subject+be的形式,从语法上来说,这个是可以省略的。当出现省略了这种subject+be的形式的其它选项,并且那个选项没有其它语法错误的时候,更好的选择时选择那个省略了这种结构的选项。作者: 斩黑4 时间: 2014-7-9 10:40
赞同洗发水的回答:如果E改成 laws that was an observation about electric current, first made in 1845, and that is now included in virtually every textbook of elementary physics.但是为什么A选项 :laws, an observation about electric current first made in 1845 and now included 为什么这里的made 和 included 要形式对称啊,不是一个过去式一个现在时吗。。。如果把从句补全了的话是不是这样的。
laws, an observation about electric current (which was) first made in 1845 and (which is) now included in
