如何攻克GMAT语法分享

　　GMAT语法是语文中相对俩说可以短期突破的一个端口。很多学生像抓住救民稻草一样死死的抓住语法不放，认为得语法者得GMAT语文，从而可以迅速占领战役的制高点从此高枕无忧。但是纵观这么多“烤鸡”的实战经验，语法哪是那么好拿下的山头啊。
　　在语法里，很多同学对于比较这一考点真是深恶痛绝；经常处于感叹语法就好像水中月镜中花一样，看似抓住了实则不然。那么我们今天一起来看看语法里面到底难在何处以及如何攻克。
　　一：比较对象标准
　　首先大家需要明确的一个点是：比较是从并列平行的一个分支。既然如此，我们就需要捎带提一下并列的基本原则。两个物体之所以可以并列，两者一定要是经过同一标准切分之后形成的小概念。例如：红色和绿色，这两者是可以并列的，因为这两者是经过同一标准（颜色）划分成的小概念；男孩和女孩，这两者是经过同一标准（性别）划分成的小概念；小孩和老人，这两者是经过同一标准（年龄）划分形成的小概念。但是我们看看能不能说：女人和老人，这显然是不符合语法标准的，我们无法判断这里的划分标准是啥。
　　二：比较词判断：
　　比较词很好识别，但是很多选项里面我们根据比较词语可以排除一两个错误选项。所以大家要对常用的比较词语敏感。
　　常见的比较词有：
　　both A and…
　　between A and…
　　not only A but also … (also是副词，not only …but …)
　　not A but…
　　neither/ either A nor/or …
　　A as…as…
　　A more than…
　　三：比较对象的判断：
　　根据上面常见比较词汇，大家可以看到比较的对象是上文中的A和省略号中的信息。
　　我们来看一个具体的例子来识别一下。

　　Eg.
　　According to a recent study, retirees in the United States are four times more likely to give regular financial aid to their children as to receive it from them.
　　A retirees in the United States are four times more likely to give regular financial aid to their children as
　　B retirees in the United States are four times as likely to give regular financial aid to their children as it is for them
　　C retirees in the United States are four times more likely to give regular financial aid to their children than
　　D it is four times more likely for retirees in the United States to give regular financial aid to their children than they are
　　E it is four times as likely that retirees in the United States will give their children regular financial aid as they are
　　这句话里面有more than，所以这里肯定是考察比较。 首先看看比较词前后是在对比什么，以及这些对的对象之间是否可比。
　　A 选项more…as的比较词不对，排除。
　　B 比较的是：retirees are likely to give regular financial aid 和 it is for them
　　比较前后不平行，排除
　　C 比较的是：likely to give regular financial aid to their children 和to receive it from them 平行，留下
　　D比较的是：likely for retirees in the United States to give regular financial aid to their children 和 they are… 不平行，排除
　　E 比较的是：likely that retirees in the United States will give their children regular financial aid 和 they are… 不平行，排除。
　　正确选项C.
