在上面的例子中我们发现，对于比较常常会将第二部分的比较词进行舍去。常见的省略形式之一是将比较的第二个所有格后的名词省略：

　　◆ My car is bigger than Brian’s [car].

　　◆ My car is bigger than Brian’s [car].

　　◆ My car is bigger than the Smiths’ [car].

　　◆ My toes are longer than Brian’s [toes].

　　◆ My toes are longer than the Smiths’ [toes].

　　对于省略我们也可以将比较第二部分中的动词，词组，甚至一整个句子省略，当然前提是不会造成歧义。

　　◆ Whereas I drink 2 quarts of milk a day, my friend drinks 3 [quarts].

　　◆ I walk faster than Brian [walks].

　　◆ I walk as fast now as [I walked] when I was younger.

　　而有时为了避免产生歧义我们也会加入助动词，如be ,do 和have 等：

　　◆ Ambiguous: I like cheese more than Yvette. (Yvette could be subject or object.)

　　◆ Right: I like cheese more than Yvette DOES. (= than Yvette likes cheese)

　　◆ Right: I like cheese more than I DO Yvette. (= than I like Yvette)

　　而在GMAT考试中，有时也容许不需要的助动词的存在：

　　◆ Right: Apples are more healthy to eat than caramels.

　　◆ Right: Apples are more healthy to eat than caramels ARE.

　　所以在考试中，我们不要因为多余的助动词而排除了正确的选项。
