宾语从句的定义
宾语从句在复合句中充当主句的宾语,通常由引导词引出,放在及物动词、介词或形容词之后。
结构:主句 + 引导词 + 从句(陈述句语序)
- 例:I know (that) he is a teacher.
- 例:She asked if I liked music.
三大核心考点
引导词的选择
类型 引导词 用法说明 例句
陈述句 that(可省略) 陈述事实,无疑问含义 He said (that) he was tired.
一般疑问句 if / whether 表示“是否”,句尾无疑问号 I wonder if/whether she will come.
特殊疑问句 what, when, where, why, how, who 等 | 保留原疑问词,但用陈述语序 Do you know where he lives
注意:
-whether后可加 or not,但 if不能:
I don’t know whether he will come or not.
I don’t know if he will come or not.
2. 从句的语序
宾语从句必须用陈述句语序(疑问词 + 主语 + 谓语),不是疑问句倒装语序!
- Could you tell me where is the park
- Could you tell me **where the park is**
- She asked what did I do yesterday.
- She asked **what I did yesterday**.
口诀:引导词后跟陈述,主谓顺序不能错!
3.时态一致性
主句时态 从句时态规则 例句
现在时/将来时 根据实际时间灵活变化 He says (that) he likes apples.
He will ask if you are free.
过去时 从句用对应的过去时态 She said (that) she was tired.
He asked when I had finished homework.
客观真理 从句永远用一般现在时 The teacher told us the sun rises in the east.
易错点:
- He asked what your name is. (主句过去时,从句需用过去时)
- He asked what your name was.
三、特殊注意事项
1. 省略 that 的情况:
- 当从句较短且无歧义时,that 可省略:
I think (that) he is right.
2. whether 与 if 的区别:
- 介词后、不定式前、与 or not 连用时,只能用 whether:
We talked about whether to leave.
We talked about if to leave.
3. 否定转移:
- 当主句谓语是 think, believe 等,且主句主语为第一人称时,从句否定转移到主句:
I don’t think he will come. (实际含义:He will not come.)
四、中考高频易错题类型
1. 语序错误:
- Do you know where does he live
- Do you know where he lives
2. 时态错误:
- She asked if I can swim. (主句过去时,从句需用 could)
- She asked if I could swim.
3. 引导词混淆:
- I don’t know that he is a teacher. (疑问含义用 if/whether)
- I don’t know if/whether he is a teacher.
五、复习口诀
“一选引导词,二改陈述序,三看时态变,真理永不变!”
真题演练建议:
1. 熟记引导词的选择规则,区分 if/whether 的特殊情况。
2. 每日练习 5 道语序调整题,强化陈述句语序意识。
3. 整理错题本,重点标注时态和语序错误。
掌握以上内容,宾语从句中考无忧!
