1、从句原形是陈述句的，由that引导。
二 .宾语从句的引导词（连接词）
无词义，
不充当成分，
只起连接作用，
练一练：
I hear ( ) _______________________.
（一小时后他将会回来）
He thinks ( ) ___________________.

找一找规律！

2.从句原形是一般疑问句的，由 whether, if 引导。
e.g.
Is she right
I want to know if/whether she is right .
“Can they visit the museum ”
They wonder if/whether they can visit the museum .
if/whether 引导宾语从句 表示“ ”
之义，在句中 句子成份。

不充当
if 与whether 的区别

（ 谁的，作定语）
2)Could you tell me why the train is late

三、 宾语从句的语序
无论主句是陈述句还是疑问句，宾语从句都是运用陈述句的语序，即 “ ”的顺序。
主+谓V+其它
改一改
将下列一般疑问句变成陈述句。
1. Can he swim → swim .
2. Does he have a pen → a pen .
3. Is your mother cooking → mother .
4.Which place did you go → you .
He can
He has
My is cooking
说一说
将上面的句子置于一个主句后，变成一个宾语从句。
Can you tell me/I want to know/I wonder/Please tell me……
e.g. Can you tell me if/whether he can swim
Which place went
四、宾语从句中时态的变化
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.
Jim ( learn )1000 Chinese words by the end of last term.
填一填
was
is
will cook
is singing
has been
was playing
had learned
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）
主现从随意
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，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 .
4) He has finished his work.
1) He to Hong Kong .
2) He sick.
3) He a book .
4) He
He said
辨一辨
would go
was
was reading
his work.
had finished
主过从过
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，不受主句时态的限制，仍是用一般现在时态。（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.
比一比
从真理，一般现在永不变！
比一比
I don’t know where I should go.（复合句）
I don’t know where to go. （简单句）
Tell me how I can do it. （复合句）
Tell me how to do it. （简单句）
结论：由连接代词和连接副词引导的宾语从句变简单句的方法：
五、宾语从句与简单句的转换
①
②
主语+情态动词 to
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 .
3.Can you tell me how to get to the bus stop
(变为复合句）

bus stop
4.Please tell Lucy how to use the MP5 .
(变为复合句）

what to do
which book to buy
how I can get to
how she can use
六 、宾语从句否定的转移
当主句的谓语是think , believe, suppose，expect 等动词时，其后作宾语的that从句如果表否定意义，通常将否定词not移至主句动词之前,即将主句谓语动词变为否定式。如：
I think they have finished their work.（变为否定句）
→ I don't think they have finished their work.
我认为他们还未完成他们的工作。
