GMAT語法比較之如何判斷比較對象
GMAT語法是語文中相對倆說可以短期突破的一個端口。很多學生像抓住救民稻草一樣死死的抓住語法不放，認為得語法者得GMAT語文，從而可以迅速佔領戰役的制高點從此高枕無憂。但是縱觀這麼多“烤雞”的實戰經驗，語法哪是那麼好拿下的山頭啊。
在語法裡，很多同學對於比較這一考點真是深惡痛絕；經常處於感嘆語法就好像水中月鏡中花一樣，看似抓住了實則不然。那麼我們今天一起來看看語法裡面到底難在何處以及如何攻克。
一：比較對象標準
首先大家需要明確的一個點是：比較是從並列平行的一個分支。既然如此，我們就需要捎帶提一下並列的基本原則。兩個物體之所以可以並列，兩者一定要是經過同一標準切分之後形成的小概念。例如：紅色和綠色，這兩者是可以並列的，因為這兩者是經過同一標準（顏色）劃分成的小概念；男孩和女孩，這兩者是經過同一標準（性別）劃分成的小概念；小孩和老人，這兩者是經過同一標準（年齡）劃分形成的小概念。但是我們看看能不能說：女人和老人，這顯然是不符合語法標準的，我們無法判斷這裡的劃分標準是啥。
二：比較詞判斷：
比較詞很好識別，但是很多選項裡面我們根據比較詞語可以排除一兩個錯誤選項。所以大家要對常用的比較詞語敏感。
常見的比較詞有：
both A and…
between A and…
not only A but also … (also是副詞，not only …but …)
not A but…
neither/ either A nor/or …
A as…as…
A more than…
三：比較對象的判斷：
根據上面常見比較詞彙，大家可以看到比較的對象是上文中的A和省略號中的信息。
我們來看一個具體的例子來識別一下。
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
這句話裡面有more than，所以這裡肯定是考察比較。 首先看看比較詞前後是在對比什麼，以及這些對的對象之間是否可比。
A 選項more…as的比較詞不對，排除。
B 比較的是：retirees are likely to give regular financial aid 和 it is for them
比較前後不平行，排除
C 比較的是：likely to give regular financial aid to their children 和to receive it from them 平行，留下
D比較的是：likely for retirees in the United States to give regular financial aid to their children 和 they are… 不平行，排除
E 比較的是：likely that retirees in the United States will give their children regular financial aid 和 they are… 不平行，排除。
正確選項C.
