二、宾语从句三要素
引导词
时态
语 序
他叫什么名字？
他怎么去上学？
What is his name
I don't know what_________________________
__________________________
is his name.
he goes to school.
宾语从句用陈述句语序：引导词+主语+谓语+其他成分
How does he go to school
his name is.
（ × ）
（ √ ）
I don't know how______________________
Task 1: Correct the mistakes：
1.I want to know what is it.
I want to know what it is.
2.I can’t understand why was he late for school.
I can’t understand why he was late for school.
3.I don’t know whose bike is this.
I don’t know whose bike this is.
① 当从句为陈述句时，连接词用that。that在句中无意义,在口语中可省略.
e.g. The earth goes around the sun. I know…
He will be back in an hour. I think…
看从句的的类型
I know ______the earth goes around the sun.
I think ______ he will be back in an hour.
that
that
二、引导词①
② 当从句为一般疑问句时，连接词用if或whether。
e.g. Is Alice 15 years old I wonder…
看从句的的类型
I wonder ___________Alice is 15 years old.
More practice:
I want to know… Does he like coke
if / whether
I want to know ________ he likes coke.
二、引导词②
if / whether
只能用whether不能用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：
They asked me whether to go skating.
3.当与or not连用时：
I don’t know whether he’s free or not.
Task 2 :Have a try :
if / whether
1. I asked her __________ she had a bike.
2. We’re worried about ________ he is safe.
3. I wonder ___________ he is well.
4. I don’t know ________ or not he is well.
5. I don’t know _______ to go.
if / whether
whether
whether /if
whether
whether
二、引导词③
③ 特殊疑问句用作宾语从句时，用原句中的疑问词引导。注意：要将疑问句语序改为陈述句语序
1.Who are you waiting for Can you tell me
=Can you tell me who you are waiting for
2.What did he do yesterday I don’t know.
=I don’t know what he did yesterday.

2. Do you know_________________________
3. He asked_______________________________.
4. Do you know _________________________
5. Please tell me _____________.
6. Can you tell me ________________________

who could answer the question
whom they are waiting for
whose bike was the best in the class
when we’ll have a meeting
where he is
how I can get to the station
why the train is late
由疑问代词 Who, whom, whose, which, what
和疑问副词 where, how, why, when引导的宾语从句
代词或副词连接主句和从句，并在从句中担任句子成分，具有一定的意义，不可省略。
1. Can you tell me___ you were born, Betty A. who B. what C. when D. that 2. I hardly understand___ he has told me. A. that B. what C. which D. who 3. She doesn't know___ back or not. A. whether B. if C. when D. what

Task 3 : Practice makes perfect !
三、时态
你昨天什么时候起床的？
你每天几点到校？
你明天几点出发？
When did you get up yesterday
When do you get to school every day
When will you start tomorrow
I wonder…
I wonder when you _________ up yesterday.
I wonder when you _________to school every day.
I wonder when you _________ tomorrow.
主现从随意
got
get
will start
三、时态
What is your favourite activity
What is he doing
My father will go to Beijing next week.
He has finished his homework.
I know…
I knew what your favourite activity_______.
主过从四过
I knew my father __________to Beijing next week.
I knew he ______________his homework.
I knew what he_____________.
was
was doing
would go
had finished
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。（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.
对比：
用所给动词的适当形式填空:
从句若为客观真理、自然现象，不受主句时态影响
主句若为过去时,从句也要用过去.
came
was
would
had
主句若为现在时，从句时态随句意.
is
goes
will rain
are doing
Task 4 :Try your best !
记忆小锦囊
1.学习宾从三要素:语序时态引导词.
2.时态主从要呼应:
①主句若为现在时, 从句时态随句意;
②主句若为过去时, 从句时态变过去; 语序要用陈述序,切莫照搬疑问句.
3. ①That 连接陈述句, 省与不省没关系;
②从句若表“是否”时,if,whether 均可以;
③特殊问句作宾语, 一定要用陈述序; ④宾从表达是真理, 一般现在代过去.
