GMAT OG语法第三遍终于做完了,随手整理了一些OG中的重点(结合OG题后解释和XDF课堂的讲解),希望对大家有用,有错误的地方也请大家批评,哈哈。下面的编号是与OG的题号一致的。
1.现在分词强调重复性;定语从句强调一次性
2.①A of B结构中,A是中心词,谓语动词与A一致

‘s用于有生命的对象(树没有生命)
3. ①to do A, to do B, and to do C对
to do A, do B, and do C对
②情态动词可否省,亦看第二个
③肯定句用and,否定句用or
④仅有no/not代表否定句
5. 句中出现any,要判断是否为语气词(强烈语气),若是,则要保留。
6. ① 主语

②there be 表自然存在状态
③语气词不能省
11. ①分词结构(doing/done,介词+分词,连词+分词)的省略结构的逻辑主语是后面主句的主语
②base/compare只用于被动语态
12. ①同一句话中,相同的代词(可能不同格)必须指代相同的对象
②代词先于主句出现,一般指主句主语,但在下句中则指代不清:
