知识梳理
我们 知道 姚明。
We know Yao Ming．
We know
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。
什么是宾语从句？
宾o
宾o
主s
谓v
he is a famous basketball player.
that
连接词
我们 知道 他是一个著名的篮球运动员。
谓v
主s
有哪些句子可以做宾语？
1. 陈述句
He is a famous basketball player.
2. 一般疑问句
Will our teachers attend the meeting
3. 特殊疑问句
Which coat did you prefer
that引导的宾语从句
当宾语从句是陈述句时（包括肯定句和否定句），连词由that引导(可省略)。主句的谓语动词常常是 think, hear, hope, wish, remember, forget, know, say, guess等。
1. Lin Tao feels (that) his own team is even better.
2. She says (that) she won't take part in the sports meeting
next Sunday.
3. Jim thought (that) the train was like a big moving party.
4. He said (that) he would like to see the headmaster.
5. I hope (that) he will be fine soon．
在主句为动词be加某些形容词（如sorry, sure, afraid, glad等）作表语时，后面所跟的省略that的从句也可算是宾语从句
I'm sorry (that) I don't know.
We're sure (that) our team will win.
I'm afraid (that) he won't pass the exam.
拓展：宾语从句中时态的变化
1. 当主句是一般现在时，宾语从句的时态不作限制，我们可以根据句子的需要使用任何一种时态。（需要性原则）
I hear
(that)
Jim _____(be)a worker two years ago.
Jim _____(be)an English teacher now.
Jim ________(cook)dinner tomorrow.
Jim ________(sing)a popular song now.
Jim _______(be)to the Great Wall twice.
Jim __________(play)basketball when his father came back.
is
will cook
is singing
has been
was playing
was
2. 当主句是一般过去时的时候，宾语从句必须用相对应的过去的某一种时态，从而达到主句和从句的相互一致。（呼应性原则）
1)He will go to Hong Kong.
2)He is sick.
3)He is reading a book.
He said
(that)
1)He __________to Hong Kong.
2)He __________sick.
3)He ___________a book.
would go
was
was reading
确定从句的时态(根据主句时态)
主句时态
从 句 时 态
连 接 前
连 接 后
一般现在时
时态保持不变
一般过去时
一般现在时
一般过去时
一般过去时
过去完成时
一般将来时
过去将来时
现在进行时
过去进行时
现在完成时
过去完成时
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。（特殊性原则）
He told me (that) Summer is after Spring.
I was told (that) the sun is much bigger than the moon.
My parents told me (that) no news is good news.
Sandy is chatting online with Millie about room colours. Try to add that to each object clause.
Millie: Did you know there is a relationship between colours and moods
Sandy: Certainly. I think colours influence our everyday lives in many ways.
Millie: How should we choose the colours for the rooms of a house
Sandy: Most people think light colours are better than dark ones.
Millie: Yes. I notice light colours make rooms seem larger.
Sandy: Sure. I also know blue can make us feel relaxed.
Millie: Yes. My mum says blue is suitable for bedrooms. I also find some
people prefer orange for their dining rooms.
Sandy: True, but it depends on personal taste. Anyway, we should choose
the colour which makes us feel comfortable.

if或whether引导的宾语从句
一般疑问句做宾语
我问他是否想去游泳
1. 改为陈述句语气
2. 用if/whether连接
I ask
Does he want to go swimming
he wants to go swimming
If/whether
I ask
由if或whether引导的宾语从句。If和whether在句中的意思是“是否”。 谓语动词常为ask, see, wonder and find out。从句的语序必须是陈述语序。
一般疑问句做宾语
I want to know if (whether) he lives there.
He asked me whether (if) I could help him.
I want to find out whether he is suitable for the job or not.
宾语从句中的人称代词要符合逻辑，有时需进行合理变化。
She wonders, “Can I keep that book for one more week ”
She wonders if/whether she can keep that book for one more week。
她想知道那本书她能不能再借一个星期。
“Can you help me ” she asks.
She asks if/whether I can help her. 她问我能不能帮助她。
拓展：宾语从句只用whether不用if的情况。
1.在介词后面：
We are worried about whether it will rain tomorrow.
2.在动词不定式前：
He can't decide whether to go to Canada.
3.当与or或or not连用时:
I don't know whether he's free or not.
She asks me whether I am from Yancheng or Nanjing.
4.宾语从句提前时：
Whether this is true or not, I can't say.
