gmat 语法

先从 og 做起，仔细研究每个选项的讲解。不清楚的地方查阅以前的精彩讨论。GMAT 语法十分灵活，即便是各种语法书的相关讲解也都太过死板。GMAT 的语法原则只有两个，即从corrective到effective

引用大大N 薰衣紫草的回帖

以下是引用LRzealot在2005-8-28 16:56:00的发言：

请教
            薰衣紫草 j ， OG解释中关于correctiveness和effectiveness的具体表现在那里啊。自从看到你今年五月在SC版发的帖子后，我一直在OG中寻
            找ETS关于correctiveness和effectiveness的线索。但是无能，没有发现。
            请问可以拿一个OG题目的解释作为例子吗？展示OG是如何按顺序解释这个问题的？

OG P.652 这是ETS自己对于correctness and effectiveness的解释, 也是你在考试前能读到的一段说明:
                

This question tests correctness and effectiveness of expression. In choosing your answer, follow the requirements of standard written English; that is, pay attention to grammar, choice of words, and sentence construction. Choose the answer that produces the most effective sentence; this answer should be clear and exact, without awkwardness, ambiguity, redundancy, or grammartical errors.
                

所以按ETS的理解:
                

correctness的错误: grammar, choice of words, sentence construction.
                

effectiveness的错误: awkwardness, ambiguity, redundancy, grammartical errors (只影响句字的clear and exact)
                

OG的解释在分析每一个问题都会提到以上几个方面, 这就是标准.

建议楼主看看薰衣紫草的总结
