语法知识：宾语从句
导入What’s the difference between two sentences IlikeAngelababy.主语 谓语 宾语Ithink( that ) she is very beautiful.主语 谓语 宾语总结： 当宾语的位置上不是单词或词组而是句子的时候整个句子就是宾语从句。活动与探究（温馨提示：规范操作、注意安全）
知识讲解
一、宾语从句连接词:
1.陈述句
2.一般疑问句
3.特殊疑问句
that
if /whether
原有的连接代词
和连接副词
二、宾语从句：主语+谓语（陈述句的语序）
三、宾语从句中时态的变化
1.当主句是一般现在时，宾语从句的时态根据句子的需要使用任何一种时态。（主现从任意）
2.当主句是一般过去时的时候，宾语从句必须运用相应的过去的某一种时态。（主过从任过）
3.当宾语从句说明的是客观存在的事实或者是客观存在的真理时，就不用受到主句时态的限制，仍是用一般现在时态。（从真理用一般）
四、宾语从句的否定转移：
如果主句的谓语动词是 think, believe, guess , suppose 等，而且主句的主语又是第一人称时，它后面接的宾语从句的否定词通常要前移到主句中，即否定主句中的动词，而从句用肯定形式。
即：主语为第一人称，否定在主句，翻译在从句。
练一练
1.I don’t know what I shall do next .(变为简单句）
→ I don’t know next .
2.John didn’t decide which book he would buy .(变为简单句）
→ John didn’t decide .
比一比
I don’t know where I should go. Tell me how I can do it.
I don’t know where to go. Tell me how to do it.
你有什么发现？
结论：由连接代词和连接副词引导的宾语从句 ←→疑问词 + to do 的简单句。
五.宾语从句与简单句的转换
①
②
What to do
which book to buy

小结
语法知识：疑问词引导的宾语从句的用法
I like my teacher.（名词作宾语)
I enjoy playing basketball.(动名词作宾语）
I decide to study hard.（不定式作宾语）
I know him .（代词作宾语）
宾语是动作、行为的对象，是动作的承受者。
宾语由名词、代词、不定式
或相当于名词的词、短语来担任。
宾语从句就是由一个句子来构成主句的宾语，并有一个连接词引导。
宾语？
宾语从句？
疑问词：疑问代词(what、whom、who、whose、which)疑问副词(when、where、why、how)。
Objective clauses with wh-questions
无论主句是陈述句还是疑问句, 也无论主从句间是什么引导词, 宾语从句一律用陈述语序, 即“引导词 + 主语 + 谓语 + 其他”。如：
Could you tell me where Wei Fang lives
语序
1. 如果主句是一般现在时或一般将来时, 宾语从句的时态不受限制, 可根据实际表达的需要来确定。如：
Jenny knows the man was flying a kite at that time.
You will understand why I did it one day.
总有一天你会明白我为什么那样做。
时态
2. 如果主句是一般过去时, 宾语从句用过去时态的某种形式。如：
I thought he had gone to town that day.
我以为他那天进城去了。
3. 如果宾语从句叙述的是客观事实、自然现象或科学真理等，从句不受主句时态的限制，用一般现在时。如：
He said time is money.
他说时间就是金钱。
