"does" 是一个助动词，它主要用于构成疑问句，表示询问某件事情是否发生或者是否正确。在英语中，"does" 后面可以接以下几种情况：
1. 动词原形：用于询问一般现在时态的动作或状态。
Does he like coffee?
Does she work in an office?
2. be动词：用于询问一般现在时态的主语身份或状态。
Is she a teacher?
Are they students?
3. have/has：用于询问一般现在时态的拥有情况。
Does he have a car?
Does she have a cat?
4. 助动词或情态动词：用于询问其他时态或情态动词。
Did you go to the party?
Can she swim?
5. 实义动词：在非正式英语中，有时也会用 "do" 来代替实义动词，尤其是在询问是否做了某事时。
Did you do your homework?
Did you eat breakfast?
当 "does" 用于疑问句时，句子通常需要倒装，即将助动词 "does" 或 "do" 放在主语之前。例如：
Does he go to school every day?
Does she speak English?
以上是 "does" 常见的用法。
