我看到有的贴说weighing直接修饰主句，忽略中间的插入语，是这样吗？作者: matthewliu1981 时间: 2010-10-4 10:42
weighing is wrong, because the final phrase can be understood to modify " the company".作者: terryhan 时间: 2010-11-20 16:04
The electronics company has unveiled what it claims to be the world’s smallest network digital camcorder, the length of which is that of a handheld computer, and it weighs less than 11 ounces. A.略. B.to be the smallest network digital camcorder in the world, which is as long as a handheld computer, weighing B选项分析： 1 由于in the world修饰camcorder，因此which可以指代camcorder，weighing现在分词做状语修饰camcorder； 2 to be the smallest camcorder in the world，不如world's smallest camcorder简洁。 3 平行结构：which is … and, weighs …平行。 PREP上的解释如下： 补充说明 [1] It claims为插入成分，这一现象大多数考生在此处为第一次遇到，因此很多考生会认为claim的正确搭配为claim to do something，因而排除BCD选项。实际上is和to be在选项中都是正确的表达：若为is，可理解为it claims是插入成分；若为to be，则可理解成what it claims to be…这一大家都很熟悉的表达。此题难度确实比较高，这个考点在此题中起到了不小的迷惑考生的作用。但是，通过以上各选项的分析不难看出，即使不考虑is和to be的区别，通过其他考点，我们也可以排除掉ACE。在实际考试中，如果考生遇到不熟悉的考点，尽量不要依据这一单一考点作判断，应比较选项中的其他差别，综合比较后再做出选择 闹闹的看法: what it claims 是名词从句(nominal relative clause, this kind of clause functions like a noun group)，是 is 的主语。what=the thing(s) which, 后面常跟 be(is or was) [2] A选项所分析的句子层次的问题，在本书P2-94题当中也有比较详尽的解析，希望考生仔细体会 [3]此题比较明显能够首先排除ACE选项，判断主要在BD当中进行。我们分析BD选项不难看出，BD之间的区别主要体现在修饰和指代上。回忆OG里关于修饰和指代的描述，我们可以得知，GMAT要求修饰成分与被修饰对象在位置上紧密相邻、指代清晰、句子平行对称。既然出题者意在考察这两点，那么我们就选择修饰最紧密、指代最清晰的选项！本题的B选项虽如上述分析，不能轻易认为其错误，但是D选项的which只能修饰camcorder，不存在修饰world这一潜在的歧义，又紧跟在其先行词之后，同时is and weighs平行对称，因此相较B而言，是更加好的答案。故此题选D。 在GMAT语法中，我们选择的不是“正确”选项，而是“最佳”选项。考生一定要在复习过程中强化“比较选项之间的差别”这一解题思路，才能在实战中取得高分成绩 闹闹的看法: B选项中的weighing修饰对象有歧义。原句中weigh的逻辑主语为camcorder，但在该选项中，如果which…定语从句与weighing现在分词结构并列修饰camcorder，两个修饰成分之间需要加连词and，因为现在分词结构在句尾可以作后置定语修饰紧临的名词，此处有修饰computer的歧义。作者: tintinc 时间: 2011-3-20 23:36
