What’s the difference between tw sentences?
I like Angelababy.主语 谓语 宾语I think ( 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）
1.陈述句2.一般疑问句3.特殊疑问句
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 , suppse 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 dn’t knw what I shall d next .(变为简单句） → I dn’t knw                     next . 2.Jhn didn’t decide which bk he wuld buy .(变为简单句） → Jhn didn’t decide                                         .
比一比 I dn’t knw where I shuld g. Tell me hw I can d it. I dn’t knw where t g. Tell me hw t d 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 + t d 的简单句。
五.宾语从句与简单句的转换
What t d
which bk t buy
一、Add the right cnjunctins (添加正确的连接词）1. He said ____ they wuld win .A. that B. which C. when2. I’m nt sure ____ it’s a gd idea .what B. hw C. if
二、把下列句子变成宾语从句1. Is June a gd time t visit Hng Kng? ( He wnders…) He wnders if June is a gd time t visit Hng Kng.2. why was I late fr schl.(He asked ) He asked me why I was late fr schl.
if／whether（一般疑问句 ）
特殊疑问词（特殊疑问句)
主句为一般现在时从句可为任何时态
宾语从句的语序都为陈述句语序
客观真理 自然现象公式定理 名言警句 时态不变
语法知识：特殊疑问词引导的宾语从句
在句子中起宾语作用的从句叫做宾语从句。 We knw that Mr. Green teaches English . She asked if these answers were right .
宾语从句的句子结构：______________________________________
主句 + 连接词（引导词）+ 宾语从句
(1)宾语从句为陈述句时，用that引导，口语中常省略。例如：He tld me (that) he wuld cme t my birthday party.(2)宾语从句为一般疑问句时，用if或whether引导。例如：She asked if/whether I culd help her with her hmewrk.(3)宾语从句为特殊疑问句时，用特殊疑问词（词组）引导。例如：I want t knw what I shuld d next.
1.宾语从句的引导词：
Where can I buy sme medicine?
Excuse me, d yu knw where I can buy sme medicine?
Hw t get t the pst ffice?
Culd yu please tell me hw t get t the pst ffice?
Observe the structures f the fllwing sentences. What are the differences?
宾语从句的连接词常见的有wh, what, when, where, why, hw 等。 从句用一般陈述语序:连词、主语、谓语。
When des the band start playing this evening?
Culd yu tell us when the band starts playing this evening?
Where shuld we g next?
I wnder where we shuld g next.
Culd yu tell me when he left fr Japan?
When did he leave fr Japan? Culd yu tell me?
2.Object clauses with特殊疑问句 由疑问词引导的宾语从句 从句一定要注意用陈述语序。
主句使用现在时，从句可使用任何时态；主句使用过去时态，从句一律使用过去时态。当宾语从句是客观真理或不可改变的自然现象时，宾语从句须用一般现在时，不受主句时态的限制。
I think that yu are right.
Lin Ta thught the TV play was very bring. 
Our teacher tld us that light travels faster than sund.
宾语从句的时态取决于主句的时态。
