【被动语态英语怎么说】在英语学习中，被动语态是一个非常重要的语法点。它用于强调动作的承受者，而不是执行者。了解“被动语态”在英语中的表达方式，有助于提高语言理解和写作能力。
一、被动语态的基本结构
被动语态的基本结构是：be + 过去分词（V-ed）。根据不同的时态，be 的形式也会发生变化。以下是常见的几种时态及其对应的被动语态结构：
| 时态 | 主动语态 | 被动语态 |
| 一般现在时 | He writes a letter. | A letter is written by him. |
| 一般过去时 | He wrote a letter. | A letter was written by him. |
| 一般将来时 | He will write a letter. | A letter will be written by him. |
| 现在进行时 | He is writing a letter. | A letter is being written by him. |
| 过去进行时 | He was writing a letter. | A letter was being written by him. |
| 现在完成时 | He has written a letter. | A letter has been written by him. |
| 过去完成时 | He had written a letter. | A letter had been written by him. |
| 将来完成时 | He will have written a letter. | A letter will have been written by him. |
二、被动语态的使用场景
1. 当动作的执行者不重要或未知时
- 例句：The book was published in 2020.（这本书于2020年出版。）
2. 强调动作的承受者
- 例句：The cake was eaten by the children.（蛋糕被孩子们吃掉了。）
3. 在正式或科技类文章中常用
- 例句：The experiment was conducted in the laboratory.（实验是在实验室进行的。）
4. 避免提及动作的执行者
- 例句：The window was broken.（窗户被打碎了。）
三、被动语态与主动语态的转换
将主动语态转换为被动语态时，需要注意以下几点：
- 主语变为宾语
- 宾语变为主语
- 动词变为被动结构（be + V-ed）
- 可以加上“by + 执行者”（可省略）
例如：
- 主动：They built the house.
- 被动：The house was built by them.
四、常见错误提示
1. 混淆时态
- 错误：The letter is wrote by me.
- 正确：The letter was written by me.
2. 忘记使用“be”动词
- 错误：The problem solved yesterday.
- 正确：The problem was solved yesterday.
3. 忽略“by”的使用
- 错误：The car broken.
- 正确：The car was broken (by someone).
