掌握被动语态to还原秘诀，让你的英语表达更地道！

1. 理解被动语态的基本形式：

- 主动语态（SVO）: 主语 + 动词 + 宾语

- 被动语态（SVC）: 主语 + 动词 + 间接宾语 + 直接宾语

- 有时，为了强调动作的承受者，可以省略间接宾语，形成“无宾语”被动语态（SVO）。

2. 识别并使用适当的时态：

- 一般现在时：I am being trained by my teacher.

- 一般过去时：She was taught by her teacher.

- 一般将来时：He will be taught by his teacher.

- 完成时：The work has been finished.

- 现在完成时：The work has been finished.

- 过去完成时：The work had been finished.

3. 注意被动语态中的动词变化：

- 有些动词在被动语态中会发生变化，例如：

- 原形动词变成第三人称单数形式：become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become, become
