八年级下英语期末复习宾语从句课件（20PPT无素材）

(共20张PPT)
The Object Clauses
仁爱八下
宾语从句是主从复合句的一种。主句是主
体，从句从属于主句，不能独立。宾语从句
当中的从句在全句中作宾语。宾语从句与主
句之间需用引导词来连接。
Look and think
1. I know her name .

S + V + O

2. I know what her name is .

S + V + ?
O-clause
宾语从句顺口溜
宾语从句有三关，语序时态引导词。
语序就一句，从句永陈诉。
时态仔细辨，从句随主句：主句一般现，从句看句意；主句一般过，从句选过去。若为真理故，时态亦可抛（一般现在时）。
引导词有三类，陈述句子选that，一般疑问加是否（if，whether），特殊疑问词不变。
三关过后莫得意，还有以下需注意：
人称标点大小写，从句简化如果(if) 时(when)。
Read and learn
She asks .
Will Mr. Li be your English teacher ?
She asks if / whether Mr. Li will be my English teacher .

Do you know ?
What is your teacher doing ?
Do you know what your teacher is doing ?
1.语序关---从句永陈诉
2.时态关---Read and learn
She says that she is a student.
She said that she was a student.
She says that she will fly to Japan .
She said that she would fly to Japan.
She says that she can sing a song in English .
She said that she could sing a song in English.
She said that the sun rises in the east.
主句一般现，从句看句意； 主句一般过，从句选过去。 若为真理故，时态亦可抛（一般现在时）。
3.引导词关：陈述句子用that：（Unit 7 Topic1 P55-62）

宾语从句中当陈述句充当宾语时，由that来引导，that 在口语或非正式文体中常省略。如：
I know (that) he is from Canada.
I think (that) we can have it on our school playground.
Maria says (that) she doesn’t like the uniforms.


注意：当主句谓语动词为think，suppose， expect，believe 等时，其后的宾语从句为否定句时，常将否定词not从从句中移到主句中，构成否定转移。
Eg. I don’t think it’s polite to do so.

含有一般疑问句的宾语从句由 if和whether 引导，意为“是否”，两者通常能互换，但不可省略。 E.g:
I don’t know.
Is it polite in Japan？ （改为复合句）
I don’t know if /whether it is polite in Japan.
引导词关：一般疑问加是否whther / if
（ Unit 7 Topic2 P63-69）
把下列句子合并成一个含有宾语从句的复合句。
1. I don’t know. Is she a teacher?


2. Do you know? Will it rain tomorrow?


3. Could you please tell me? Is your father at home or not?


I don’t know if / whether she is a teacher .
Do you know if /whether it will rain tomorrow ?
Could you please tell me whether your father is at home or not ?
只能用
1.与or not 连用时 I want to know whether he can come or not.
2.作介词的宾语时It depends on whether they will support us .
3.句首Whether this is true , I can’t say.
4.和动词不定式连用时He doesn’t know whether to go .
5.句中已有if引导的条件状语从句时，避免歧义Please let me know if you like it .
二、只能用whether
if/whether 篇外
一、if还可表如果，此时不是宾语从句，是条件状语从句。
Eg： I will stay at home if it rains tomorrow.
引导词关：特殊疑问词不变 Unit 8 Topic2 P90-95）
Can you tell me what Miss Wang says?
拆散为(1)Can you tell me ?
(2) What does Miss Wang say ?两个简单句
可以看出把特殊疑问句转为宾语从句的变化步骤：
①引导词：疑问代词 / 副词(不能省略)；
②语序：陈述句语序，即“主语+谓语+其它”
③人称变化 ④时态变化 ⑤ 标点大小写
E.g:Can you tell me ? Who is he waiting for ?
Can you tell me who he is waiting for ?
He asked me. Where are you going ?
He asked me where I was going .

。
注意：I’ll tell him the news when he comes .（引导时间状语从句）
特别提醒
The doctor asked the young man what was wrong / what was the matter with him.
what 是宾语从句的主语，也是宾语从句的连接代词，was是连系动词，wrong / the matter 是表语。
综合运用改错：
1).I want to know that what it is.
I want to know what it is.
2).I can’t understand that the teacher said.
I can’t understand what the teacher said.
3).I don’t know this is whose bike.
I don’t know whose bike this is.
5).He asked me where was Mary.
6).Do you remember how much did you pay for the book?
He asked me where Mary was .
Do you remember how much you paid for the book?
4).She said that she will be back soon.
She said that she would be back soon.
7).The teacher told us that light traveled much faster than sound.
The teacher told us that light travels much faster than sound.
8).Could you tell me if Miss Gao was in the office now?
Could you tell me if Miss Gao is in the office now?
9).I think you are not right.
I don’t think you are right.
宾语从句可以简化为变为简单句。常见情况有三：
1.不定式结构
He hopes that he will be back very soon.
He hopes to be back very soon.（主从句主语为同一人或物）
He find it is important to learn English well.
He find it important to learn English well.
2.宾语+V-ing形式（宾补）
I saw some children were flying kites.
I saw some children flying kites.
3. “疑问词+不定式”结构
Please tell me where we show our tickets.
Please tell me where to show our tickets.
宾语从句由连接代词（what ,which ,who , whom等）或连接副词（how , when, where, whether 等）引导，可以将其简化。
宾语从句的简化
Summary 宾语从句三要素
1.语序
2.时态
主句
一般现在时
一般过去时
从句
按实际情况用相应时态
过去的某种时态（U8T3 P97-103）
Does he like Times Post ? Do you know ?
Do you know if /whether he likes Times Post?
I heard you had a bad cold.
从句永陈诉
注意：若为真理故，时态亦可抛（一般现在时）。
如果从句说的是客观现象或真理，无论主句是什么时态，从句都用一般现在时。
Eg:The teacher said that the earth goes around the sun.
时态须辨清，从句随主句。主句一般现，从句看句意；
主句一般过，从句选过去。
Summary :宾语从句三要素
3.引导词的选择

（P63-69）
（P90-95）
（P55-62）
特殊疑问词不变
陈述句子选that， (可省)
一般疑问要是否if / whether
Eg.I know (that)he is from South Africa.
Eg.Could you please tell me where the nearest bank is ?
Eg. I don’t know whether he is right or not.只能

Writing with Object-clauses
My friend
Jane is one of my friends. She is a beautiful girl. She smiles frequently( very often ). I think it’s her smile that makes her pretty.
At first, I don’t like her very much, because she is outgoing and always talking but I am a little bit quiet, I seldom talk to others. But later I find that she can have influence (effect) on others by what she says. She always tells me that I should learn to talk to others. Under the influence of her, I communicate with others more and I find that it feels so great. I feel that I am so lucky to have such a good friend.
