【宾语从句解释及例句,练习】在英语语法中,宾语从句是一个非常重要的知识点,尤其在句子结构和表达复杂意思时起着关键作用。很多学习者在遇到宾语从句时感到困惑,不知道如何正确使用或判断其位置和形式。本文将对宾语从句进行详细讲解,并结合实例帮助大家更好地理解和掌握。
一、什么是宾语从句?
宾语从句是指在主句中充当宾语的从句。它通常由一个引导词(如 that, whether, if, what, when, where, why, how 等)引导,用来说明主句中动词所“接受”的内容。
例如:
- I think that he is right.
(我认为他是对的。)
这里的 “that he is right” 就是宾语从句,作 “think” 的宾语。
二、宾语从句的常见引导词
| 引导词 | 用法说明 |
|--------|----------|
| that | 引导陈述性从句,常省略不写 |
| if / whether | 引导疑问性从句,表示“是否” |
| what| 引导名词性从句,表示“什么” |
| when| 表示时间 |
| where | 表示地点 |
| why | 表示原因 |
| how | 表示方式 |
三、宾语从句的语序
宾语从句中的语序应为陈述语序,而不是疑问语序。
错误:I don’t know what does he want.
正确:I don’t know what he wants.
四、宾语从句的时态一致性
宾语从句的时态一般要与主句保持一致,但如果是客观事实或普遍真理,可以用一般现在时。
例如:
- She says she is going to the party.(现在时)
- He said he was tired.(过去时)
- The teacher explained that the earth orbits the sun.(客观事实)
五、宾语从句的例句分析
1. He asked me whether I had finished my homework.
(他问我是否完成了作业。)
- “whether I had finished my homework” 是宾语从句,作 “asked” 的宾语。
2. She believes that she can pass the exam.
(她相信她能通过考试。)
- “that she can pass the exam” 是宾语从句,作 “believes” 的宾语。
3. Can you tell me where the nearest station is?
(你能告诉我最近的车站在哪里吗?)
- “where the nearest station is” 是宾语从句,作 “tell” 的宾语。
