助动词与be动词，在英语语法中扮演着截然不同的角色。今天，咱们就来聊聊这两者的核心区别。
| 类别 | 单词 | 说明 |
|---|---|---|
| be动词 | am, is, are, was, were | 现在时与过去时形式，描述主语状态 |
| 助动词 | do, does, did, shall, will | 协助构成时态、语态及疑问句、否定句 |
| 助动词 | 时态/语态 | 示例 |
|---|---|---|
| do/does | 现在时 | Do you like it? |
| did | 过去时 | Did you finish it? |
| shall/will | 将来时 | I shall go. / I will go. |
| have/has been | 现在完成时被动 | The book has been read. |
| had been | 过去完成时被动 | The book had been read. |
