GMAT语法比较题的注意事项之一共包括两个小点。这两个GMAT语法比较题的小点是怎样考察的呢?小编会在下文为大家通过例题来详细讲解，下面一起来看看吧。
一、GMAT语法比较题的注意事项讲解。
1. 比较时既可倒装，也可不倒装。
例如，I play tennis better than Lao Yu does./I play tennis better than does Lao Yu.两句都是正确的，没有太大的区别。两种表达都是可以的。
2. 主语比较时，助动词习惯补出。
例如，I will be richer than Lao Yu.在这句话中，我与Lao Yu的富裕状态并没有表达的很清晰。如果我们加入助动词后，表意更明确。如下：
1)I will be richer than Lao Yu was.指我将会比Lao Yu过去富有。
2)I will be richer than Lao Yu is. 指我将会比Lao Yu现在富有。
3)I will be richer than Lao Yu will. 指我将会比Lao Yu将来富有。
注意：补出不一定对，不补也不一定错。如果主句是be动词，则than后补出的也是be动词。如果主句是实意动词，则than后补出的是do, did, does.
二、例题解析。
为了帮助大家更好地理解这一考点，前程百利小编整理了一道例题，大家可以通过这道例题更快地吸收考点知识。
Inflation has made many Americans reevaluate their assumptions about the future; they still expect to live better than their parents have, but not so well as they once thought they could.
(A) they still expect to live better than their parents have
(B) they still expect to live better than their parents did
(C) they still expect to live better than their parents had
(D) still expecting to live better than their parents had
(E) still expecting to live better than did their parents
答案：B
解析：译文，通货膨胀使得人们重新评估他们对未来的期望， ，但是不一定比他们过去设想的好。首先我们排除D和E，因为此两个选项改变了原文的重心。我们观察选项A/B/C的区别在于have/ did/ had的区别。根据意义来说，如果是“have”表示“和父母现在比”，“did”表示“和父母过去比”，“had”形式错误。显然选项B的表意更好。
