据留学360介绍，在GMAT语法中，GMAT语法比较题非常常见，但得分率往往偏低，为此小编特从比较词汇，解题法则，常见错误等方面进行详细分析，希望对大家有所帮助。
1. 常见的GMAT比较词汇:
Like, Unlike, More than, Less than, Faster than, different from, in contrast with/to, Compare to, as, as (adj.) as, as much as, as fast as, the same as.
2. GMAT比较的解题法则：
1)读语义找标志词：
① 找出逻辑概念是否可以比较; ② 注意专题中的标志词;
2)注意点：
① 看到了标志词，知道比较点双方是否存在并且是否可以比较;
(Cat’s paw和Dog;1982年和1984年的事)
② 比较双方是否形式一致;
(前后双方要保持形式一致，除非不同语态，但要保持形式一致)
③ 比较是否清晰;
注意什么和什么比：在逻辑语义上;
A, B, and C (其中AC是人，B是物，那么逻辑比较的双方是AC,语法形式是否一致)
④ 比较是否简洁(比较省略的运用)：
a. a as b 如果省略b这块的主语和谓语，那么比较就默认为b这里的主谓和a一致;
b. 比较前后的动词是否可以省略：
Ambiguous: I like cheese more than Yvette. (Yvette可以是主语或者是宾语)
Right: I like cheese more than Yvette. (=than Yvette like cheese)
Right: I like cheese more than I do Yvette. (=than I like Yvette)
. 比较最重要的看的，是两者是否可以比较;(可比性)

3. GMAT比较注意点：
原则： 选择正确的比较;
排除： 排除不正确的比较形式;
形式： 1) as...as
2) more/less/greater/higher...than
3) like/unlike (必须两个名词)
举例： The new SUV uses gas more quickly as the small sedan does 错误
The new SUV uses gas more quickly than the small sedan does. 正确
排除： 没有形成正确的逻辑比较;
原则： 在比较中，“that”可以用来替代单数物体的比较;“those”是用来比较复数的。
举例： The couches in the living room are smaller than that in the den. 错误
The couches in the living room are smaller than those in the den. 正确
Unlike the head chef, whose dishes are always healthy, the assistant chef‘s are quite unhealthy. 错误
Unlike the head chef’s dishes, whose dishes are always healthy, the assistant chef‘s are quite unhealthy. 正确
暗示： 当你看到比较选项词出现，比较词请考虑是否用比较来做题目
(比较是考察的核心，即选项里比较的差异性会是题目的考点)
4. GMAT比较题可能常犯的错误：
1)构成比较额连词搭配错误或者不完整 as..as… more..than..
通常出现的错误形式有as…than… more…as; More rather than
不完整的情况有as many后面缺少as/more 后面缺少than
2) 构成比较的形容词/副词和修饰对象的搭配错误
例句：A study commissioned by the Department of Agriculture showed that if calves exercise and associated with other calves, they will require less medication and gain weight quicker than do those raised in confinement. (A) associated with other calves, they will require less medication and gain weight quicker than do (E) associate with other calves, they require less medication and gain weight more quickly than
Quicker than和 more quickly than 选后者 E
3) 比较结构的冗余： as many as, more than同时出现的结构
In a recent poll, 86 percent of the public favored a Clean Air Act as strong or stronger than the present act.
(A) a Clean Air Act as strong or stronger than
(B) a Clean Air Act that is stronger, or at least so strong as,
(E) a Clean Air Act at least as strong as
答案是E A as strong or stronger than同时出现 直接as strong as
B 多加了一个插入语 at least so strong as
E 正确简洁
4) 几组形容词的比较级区别
① Less 指的是数字和量小，通常是不可数
There is less water in the bucket than in the pool.
I have been trying to cut back, so now I drink less coffee.
② Fewer指的数量小，通常是修饰可数名词
Express checkout: 10 items or fewer.
Gene has read only a few books on the assigned reading list.
③ lower 修饰程度
The average temperature is lower in the winter than in the summer.
Lower the water level in the pool by pulling the drain plug.
④ Amount: quantity
Degree: level or amount.
Larger/smaller ?size, amount, or number
Greater ?degree = greater level or amount
Higher/lower ?number + amount
size并不是一个测度，而是how big or small something is，一个程度
形容amount和number的时候三者都可以用higher, larger, greater。
形容size的时候可以用只larger。
形容level(程度)的时候只可以用greater。
以上就是GMATGMAT语法比较题的全面介绍，考生朋友在下次遇到GMAT语法题时，首先判断是否考察的比较形式，如果是，用文中的方法进行练习，最后祝大家都能考出好成绩。
