【宾语从句例句】宾语从句是英语语法中的一个重要知识点，它在句子中充当动词的宾语。掌握宾语从句的结构和用法，有助于提高英语表达的准确性和复杂性。以下是对宾语从句的总结及典型例句。
一、宾语从句的基本结构
宾语从句通常由一个引导词（如 that, if, whether, what, when, where, why, how 等）引导，后接主谓结构完整的句子。在主句中，宾语从句作为整个句子的宾语部分。
例如：
I think that he is coming tomorrow.
（“he is coming tomorrow” 是 “think”的宾语）
二、常见的引导词及用法
| 引导词 | 用法说明 | 例句 |
| that | 引导陈述性从句，可省略 | I said that I was tired. |
| if / whether | 引导疑问性从句，表示“是否” | She asked if/whether you are coming. |
| what | 引导名词性从句，表示“什么” | Can you tell me what happened? |
| when | 表示时间 | I don’t know when the meeting will start. |
| where | 表示地点 | Do you know where she lives? |
| why | 表示原因 | He didn’t explain why he was late. |
| how | 表示方式 | Could you tell me how to use this app? |
三、宾语从句的语序与时态
1. 语序：宾语从句必须使用陈述语序，不能使用疑问语序。
- 正确：I don’t know what he wants.
- 错误：I don’t know what does he want.
2. 时态一致性：
- 主句为一般现在时，从句可根据实际情况使用不同时间的时态。
- I believe he is working now.
- 主句为过去时，从句需用相应的过去时态。
- I thought he was working then.
四、常见错误与注意事项
1. 不要混淆 that 和 whether / if
- 在正式语境中，whether 更常用于引导选择性从句，而 if 多用于非正式语境。
- 例如：She asked whether/ if I wanted to go.
2. 避免重复使用 that
- 当多个从句并列时，只需第一个用 that，其余可以省略或替换。
- 例如：He said that he was tired and that he would leave soon.
3. 注意从句的完整性
- 宾语从句应是一个完整的句子，不能缺少主语或谓语。
- 例如：I don’t understand he is not coming.（错误）
应改为：I don’t understand why he is not coming.
