3.本单元用于询问文学作品细节
4.两大核心规则:引导词+陈述语序
5.初中从句核心必考知识点
宾语从句引导词分类(1)
引导词 功能 适用场景
whether/if 表“是否” 不确定的选择疑问
what 表“内容” 询问“是什么/关于什么”
when 表“时间” 询问“何时发生”
宾语从句引导词分类(2)
引导词 功能 适用场景
why 表“原因” 询问“做某事的原因”
who 表“人物” 询问“是谁/谁做的”
核心:从句表什么,选对应引导词
whether与if 用法小区别
二者均可表“是否”,多数情况通用
与or not连用时,只能用whether
例句:He asked if it will rain.
例句:He asked whether it will rain or not.
本单元优先掌握whether的使用
宾语从句 引导词 单元例句(1)
1.I wonder whether you like this play.
2.Do you know what the story is about?

每句对应引导词的核心功能
体会引导词与从句语义的匹配
宾语从句 引导词 单元例句(2)

2.Can you tell me who wrote Teahouse?
3.I wonder when the story takes place.

宾语从句 关键规则 陈述语序
从句结构:引导词 + 主语 + 谓语
禁止用疑问语序,不提前助动词
错误:I don’t know when does it start.
正确:I don’t know when it starts.
语序是本语法点的核心易错点
宾语从句 语序判断 示例(1)
原问句:When will the play start?
变从句:I ask when the play will start.
原问句:What is the story about?
变从句:I know what the story is about.
把疑问语序还原为陈述语序
宾语从句 语序判断 示例(2)
原问句:Why did he make the choice?
变从句:We know why he made the choice.
原问句:Who is the writer?
变从句:Tell me who the writer is.
注意时态的自然衔接
小练习2 - 宾语从句引导词选择
从whether/what/when/why/who中选择
1.I wonder _________ you like this novel.
2.Do you know _________ the book is about?

whether
what
when
小练习3 - 宾语从句语序改正
