在复合句中，由一个句子来充当宾语，这个句子叫做宾语从句。
一 、 什么是宾语从句？

Find ut the Object Clauses
宾语从句要有引导词！！
1. 他认为他需要拍个X片。 2.我知道我能完成这项工作。　　 3. 他们相信将会有更多的树。 4. 她说Tm头疼。　　
He thinks (that) he needs t get an X-ray.
　　 I knw (that) I can finish the wrk.
They believe (that) there will be mre trees .
She said (that) Tm had a headache.
that：在从句中 在口语中常被省略。
e.g. I hear (that) he will be back in an hur. He tld me (that) the meeting was ver.
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）
练一练：I hear ( ) _______________________. （一小时后他将会回来）He thinks ( ) ___________________. （我正在看电视）3. The teacher tld us ( ) ___________________________. （地球围着太阳转）
he will be back in an hur
I am watching TV
the earth ges arund the sun
1. Is it an English bk?2. Can Alice play the pian? 3. D yu like swimming?
Can yu tell me if/whether it is an English bk.
I dn't knw if/whether Alice can play the pian.
Please tell me if/whether yu like swimming.
2.从句原形是一般疑问句的，由 whether, if 引导。
e.g. Is she right? I want t knw if/whether she is right . “Can they visit the museum?” They wnder 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。
if 与whether 的区别
1.I dn’t knw _____ he will cme r depends n ____ he can cme wndered ____ t stay here the next week.
与r nt 连用只能用whether
介词后只能用whether
与不定式t d 连用只能用whether
练一练：请用if 或whether 来填空。
Can yu tell me ____________ it will rain tmrrw?I dn’t knw ____________ this bike is Bb's. 3. He wnders ____________ t sit at the frnt.4. I dn’t care f ____________ he is handsme. 5. Please tell me ____________ I have t clean the rm nw.6. I dn’t knw ____________ Lucy can dance r nt.
3.从句原形是特殊疑问句的 由 wh,whm,whse,which,what和 where,hw,why,when引导。
e.g.1)D yu knw whse bk it is ? （ 谁的，作定语） 2)Culd yu tell me why the train is late? （为什么，作状语） 3)He wnders wh can answer the questin. （谁，作主语）
这些连词既有词义，又充当句子成份。
练一练：请用wh,which,when,hw,why来填空。
-Can yu tell me ______yu learn English.? -By reading alud.2. -D yu knw _______ the mvie begins? -It begins at 8:00 .3. -I want t knw ________ yu were late his mrning. -Because I gt up late. 4. Please tell me _________ yu like better, the red ne r the blue ne.5. I wnder ________ can g shpping with me .
Helen says that she will learn French next year. D yu knw where he cmes frm? He wants t knw if I can get t the bus statin n time.
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。
将下列一般疑问句变成陈述句。     1. Can he swim ?→            swim .     2. Des he have a pen ? →            a pen .     3. Is yur mther cking ? →   mther          . 4.Which place did yu g ? → yu .
My is cking
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 yu tell me/I want t knw/I wnder/Please tell me……?e.g. Can yu tell me if/whether he can swim?
Which place went
四、宾语从句中时态的变化
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）
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 g t Hng Kng .2) He is sick.3) He is reading a bk . 4) He has finished his wrk.
1) He t Hng Kng .
2) He sick.3) He a bk . 4) He
was reading
had finished
确定从句的时态(根据主句时态)
从 句 时 态
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 tld me (that)
Summer is after Spring .
I was tld (that)
the sun is much bigger than the mn.
My parents tld me (that)
n news is gd news.
从真理，一般现在永不变！
比一比 I dn’t knw where I shuld g.（复合句） I dn’t knw where t g. （简单句） Tell me hw I can d it. （复合句） Tell me hw t d 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
主语+情态动词 t
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                                         . 3.Can yu tell me hw t get t the bus stp ? (变为复合句） → Can yu tell me                          the bus stp ? 4.Please tell Lucy hw t use the MP5 . (变为复合句） →Can yu tell Lucy                    the MP5.
what t d
which bk t buy
hw I can get t
hw she can use
六 、宾语从句否定的转移 当主句的谓语是think , believe, suppse，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nt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 wrk.（变为否定句） → I dn't think they have finished their wrk. 我认为他们还未完成他们的工作。

where t play
(that)（陈述句 ）
if／whether（一般疑问句 ）
连接代词、连接副词（特殊疑问句)
在复合句中，由一个句子来充当宾语，这个句子叫做宾语从句。
