小编为大家带来知识点：every用法，希望对大家GMAT备考有所帮助。和小编一起来看看吧！
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 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。所以答案为C。
