gmat语法，又叫句子改错(sentence correction)，是整个GMAT语文(VERBAL)三大题型中难度最高却也最容易提分的题型。说它难度高，是因为英语语法向来是中国考生的软肋，特别是对于英语基础不扎实的考生来说可谓老大难问题。至于提分容易，则是因为比起出题思路天马行空、文章难度高深莫测且基本没有规律可循的阅读和逻辑来说，GMAT语法无论是考点还是难度，都更有规律，花费同样时间精力复习往往提升更为明显。
话虽如此，想要考好GMAT语法秒解难题还是需要花上一番功夫的。特别是对于考试涉及的各类语法点和疑难杂症，考生势必要多加努力才能有所收获。下面小编就为大家汇总整理了GMAT语法考试中出现频率最高也最容易做错的语法难题，配合实例解析，为大家每日讲解。
GMAT语法知识点讲解：every 的用法说明
1. 表示“每(个)”，其后通常接单数可数名词。如： I go there every day. 我每天去那儿。
I believe every word he says. 我相信他说的每一句话。注意以下两种情况：
(1) every 通常不能用于复数名词前，但若复数名词前有基数词或few 的修饰，则也可用 every 修饰，表示“每(隔)……”。如：
We go there every three days. 我们每三天(每隔两天)去那儿一次。
(2) every 通常不能用于不可数名词前，但在少数情况下，它可用于抽象名词前，表示“所有可能的”“充分的”“完全的”等。如：
We have every reason to do so. 我们有充分的理由这样做。 I wish you both every happiness. 祝你们俩位幸福美满。
2. every 指的是三个或三个以上的“每个”，不能指两者中的每个。如： 路的两边都种有树。
误：There are trees on every side of the road. 正：There are trees on each side of the road.
3. 并列的“every+名词”结构用作主语时，谓语要用单数。如：
Every boy and (every) girl has read the story. 每个男孩女孩都读过这个故事。
4. 与not 连用通常构成部分否定。如：
Every student doesn’t like it. 并非每个学生都喜欢它。 Every man is not perfect. 并非每个人都是十全十美的
GMAT高频词汇every用法实例讲解
A recent national study of the public schools shows that there are now one microcomputer for every thirty-two pupils, four times as many than there were four years ago.
A. there are now one microcomputer for every thirty-two pupils, four times as many than there were
B. there is now one microcomputer for every thirty-two pupils, four times as many than there were
C. there is now one microcomputer for every thirty-two pupils, four times as many as there were
D. every thirty-two pupils now have one microcomputer, four times as many than there were
E. every thirty-two pupils now has one microcomputer, four times as many as
选项分析：
A、B、C三个选项都大致使用了"one X for every thirty-two Ys" 的基本结构，但只有C才是没有错误的完美答案。
A选项存在主谓不一致问题，are和one microcomputer并不匹配，所以错误。
同时在A、B和D选项中，as many than的用法搭配都是错误的，正确的用法应该是as many as。所以B和D也可以排除。
而D和E选项重新组织了句子结构，反而扭曲了句子意思，把学生数量变成了主要目标，造成了句意上的逻辑错误，因此E也可以排除。所以最后答案为C。
