宾语从句
1.宾语从句定义
宾语从句即指在主从复合句中用作宾语的从句。
宾语从句通常由连词that和whether(if)以及连接代词
或连接副词引导。宾语从句的词序要用陈述句词序，
不能用疑问句词序。
例句：我不知道他想要什么。
误:I don't know what does he want.
正:Idon't know what he wants.
2.宾语从句的引导词
(1)用that引导。that只起引导词作用，不充当句子成分，也没有词义，且通常可以省略。
翻译句子：我知道他很忙。
I know (that) he is very busy.
例句：
（1）We think(that)he will help us.我们认为他会帮助我们。
（2）He said (that)he was good at English.他说他擅长英语。
(2)用if或whether引导。if和whether引导宾语从句，
不充当句子成分，但有词义，表示“是否”。但是if 不能和or not 连用，但是whether可以。
请用if或whether填空：
① I wonder it is true.
② They don’t know it rains or not.
whether /if
whether
例句：
① She asked if /whether that was enough.她问那是否够了。
② I don’t know whether he will come or not.
我不知道他是否会来。
(3)用连接代词引导。常见的引导宾语从句的连接代词有what/who/whom/which/whose等。此时要特别注意
宾语从句用陈述句词序，而不用疑问句词序。
根据中文补全句子：告诉我这是谁的钱包
Tell me .
【注】what引导宾语从句时，有时表示“什么”，有时表示
“…所…的”。比较: l asked what he needed.我问他需要什么。
I gave him what he needed.我给了他所需要的东西。
例句：
① Ask him which he wants.问他要哪一个。
② She asked who would like to go with.她问谁愿意去。
whose wallet this is
(4)用连接副词引导。常见的引导宾语从句的连接副词有when/how/where/why等。此时要特别注意宾语从句
用陈述句词序，而不用疑问句词序。
根据中文补全句子：
①我不能告诉你她为什么哭。
I can‘t tell you .
②他没有说什么时候回来。
He didn‘t say .
why she is crying
when he would return
例句：
① He knows where they live.他知道他们住哪里。
② Tell us how you are getting on now.告诉我们你现在过得怎样
3. 宾语从句的时态
I think that you are right .
Lin Tao thought the TV play was very boring .
Our teacher told us that light travels faster than sound.
1.主句使用现在时 ，从句可使用任何时态 ；
2.主句使用过去时态 ，从句一律使用过去的某种时态 。
3.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 。
宾语从句的时态 取决于主句的时态。
4.宾语从句与否定转移
当动词think,believe,suppose,expect,imagine
后接一个表示否定意义的宾语从句时，其否定通常转移到主语。
练习：
I believe that it is not easy.
（转）I don't believe that it is easy.
例句：
I think that he will not leave.
（转）I don't think that he will leave.
我认为他不会离开。

5.宾语从句与形式宾语it
当宾语从句后跟有宾语补足语时，通常在宾语从句处使用形式宾语it，而将真正的宾语从句移至句末。
例句：
I think it best that you should stay here.
我认为你最好住这儿。
