英语句子成分种类
? 在句子中,词与词之间根据语义关系组合 在一起,表达一定的语法功能,这种语法 功能被称为句子成分。

? 英语的基本成分有七种:主语(subject)、 谓语(predicate)、表语(predicative)、 宾语(object)、定语(attribute)、状 语(adverbial) 和补语(complement)。 另有同位语(appositive)和独立成分。

一、主语 主语(subject):谓语动作的发出者,或 句首 , 谓语描述的对象。主语一般位于______ 谓语前。
1.Lucy likes her new bike.

2.We work hard.
3.To learn a foreign language is not easy.

4.Playing football after school is great fun.

一、主语 主语可以用下面这些东西表示: 1. The sun rises in the east. ( 名词 ) 2. He likes dancing. ( 代词 ) 3. Two will be enough.( 数词 ) 4. Seeing is believing. ( 动名词 ) 6. To see is to believe. (不定式 ) 7. When to hold the meeting has not been decided yet. ( 疑问词+不定式) 8. What he needs is a book. ( 从句 ) 9. It is very clear that the elephant is round and tall like a tree. (It作形式主语,that从句是真正的主语)

什么情况下用it作形式主语?

当不定式、动名词或从句在某个句子中作主语 时,为保持句子结构前后平衡,避免头重脚轻, 因此常用it作形式主语置于句首,而将真正的 主语放在句尾。此时it只起先行引导作用,本 身无词义。

你能划出下列句子的真正的主语吗?你懂得翻 译下列句子吗? 1) It is wrong to tell a lie. ( 说谎是错误的。) 2) It is no use arguing about it. (争吵是没用的。) 3) It is uncertain who will come. (谁要来还不确定。 )

情态动词和助动词不能单独充当谓语, 必须和实义动词或系动词一起构成谓语.

一、Object Clauses 宾语从句
I
主语

know him . (简单句)
谓语 宾语

I
主语 主

know who
谓语 句

he

is . (复合句)

连词 从句主语 从句谓语 宾语从句

宾语从句的概念: 宾语从句在复合句中作主句的宾语。 句子结构: 主句+连词(引导词)+宾语从句

1. 连词(引导词) 1) 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, 因为that在从句 中不作任何成分, 也没有任何具体意思, 因此在口语或非正式文体中常省略。 Lin Tao feels (that) his own team is even better. She says (that) she won’t take part in the sports

meeting next Sunday.
Jim thought (that) the train was like a big moving

party.

宾语从句中的连接词that在以下三种情况 下不能省略: ①当that 从句与另一名词性从句并列作 宾语时, 第二个that不能省; ②当that作介词宾语时, that不可省掉。 ③用it做形式宾语的宾语从句。 Everyone knew what happened and that she was worried. The reason lies in that she works harder than the others do. I think it necessary that you should read English aloud.

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.

2) 当宾语从句是一般疑问句时, 由连词whether

或if引导(口语中常用if), 因为if/whether翻译成:
“是否”, 具有一定的意义, 所以不能省略。 Lily wanted to know if /whether her grandma

liked the handbag .
Let’s see if /whether we can find out some

information about that city .
She asked me if /whether she could borrow

these books .

whether与if的辨用
表“是否”时, 在下列情况下用whether。 a. 主语从句 b. 表语从句 c. 同位语从句 e. 介词后的宾语从句 f. 后接动词不定式 (whether to do sth.) g. whether or not 连在一起引导宾语 从句时不用if

whether和if的使用区别
whether和if都可以引导宾语从句。
a. 当whether后紧跟or not时, 不用if. b. 介词后面的宾语从句不能用if.

e.g. I don’t know whether or not I will stay.

e.g. I worry about whether I hurt her
feelings.

练一练: if / whether if / whether she had a bike. 1. I asked her __________

2. We’re worried aboutwhether ________ he is
safe. 3. I don’t know whether ___________ /if he is well or not. 4. I don’t knowwhether ________ or not he is well. 5. I don’t know _______ to go. whether

3) 当宾语从句是特殊疑问句时, 由连接代词 (what, who, whom, which, whose) 或连接 副词(when, where, how, why)引导, 因为连接 代词或连接副词在从句中担任一定的句子成分, 具有一定的意义, 所以不可以省略。 Do you know what he said just now? I don’t remember when we arrived. I asked him where I could get so much money. Please tell me who (whom) we have to see. Do you know what time the plane leaves?

带how的词组也都可以引导宾语从句
Could you tell us how much it costs to fly to Hainan? Could you tell us how often you go abroad for a holiday? Could you tell us how long the meeting will last? I don’t know how far it is to the cinema. Please tell us how many students there are in your school? Please tell us how soon you will be ready. Can you tell us how old his brother is?

2. 时态
1) 如果主句是现在的时态(包括一般现在时, 现在进行时, 现在完成时)从句的时态可根 据实际情况而定(包括一般现在时,一般过 去时,一般将来时,现在完成时等)。 ?I know he lives here. ?I know he lived here ten years ago. ?I have heard that he will come tomorrow.

2) 如果主句是过去的时态(包括一般过去时, 过去进行时), 那么从句的时态一定要用相 对应的过去的某种时态(包括一般过去时, 过去进行时, 过去将来时, 过去完成时)。

?I knew who lived here. ?I saw she was talking with her mother. ?He asked whether his father would come back tomorrow. ?He said that he had seen it .

3) 当从句是客观真理, 定义, 公理, 定理 时用一般现在时。 ?The teacher said that the sun travels around the earth.

Exercise
1. I didn’t know what time hewrote _______ the letter. (write) has taken away 2. Could you tell me who _________ the book already? (take) had been to the 3. Ling Feng told me he _________ Great Wall several times. (be)

4. The radio says it _______ will be cloudy tomorrow.

(be)
goes well. 5. The headmaster hopes everything ______

(go)
were playing (play). 6. Tom says that they ____________ basketball at six o’clock yesterday evening. 7. I hear they ______________ have returned (return) it already. had been members of the 8. He said that they _________ Party since 1948. (be)

3.语序
宾语从句的语序用陈述语序:

连接词+主语+谓语+其他成分

? When will he go to the library?
? His brother asks when he will go to the

library .
His brother asks when will he go to the

library .
? What does he want to buy ? ? I don’t know what he wants to buy . I don’t know what does he want to buy .

4. 注意事项
1) could / would是委婉语气, 而不是过去式, 因此宾语从句的时态根据实际情况用不同时态。
?Could you please tell me where we show our tickets ? ?Could you tell us which gate we have to go to? ?Would you like to know when he will come back?

2) 如果主句的谓语动词是ask时, 连词不可能 是that; 如果主句的谓语动词是say时, 连词用that。 ?She says (that) she will leave a message on his desk. ?He said (that) he was going to take care of the child. ?He asks if I like playing the piano. ?You may ask the man over there how you can get to the bus station.

3) 否定的转移: 若主语谓语动词为think,
consider, suppose, believe, expect, guess,

imagine等, 其后的宾语从句若含有否定
意义, 一般要把否定词转移到主句谓语上, 从句谓语用肯定式。 I don’t think this dress fits you well. 我认为这件衣服不适合你穿。

4) It 常可以放在动词think, find, consider,

believe, feel, make等后作形式宾语:it 不
仅可以作形式主语, 还可以作形式宾语而 真正的宾语-that从句则放在句尾,特别是

在带复合宾语的句子中。
We heard it that she would get married

next month.

5) 连词 if 和 when 在不同从句中的区别: Do you know if ______back next week? If C he ______ back, please let me know. A. he comes, will come B. will he come, comes

C. he will come, comes
D. he will come, will come

主句

从句

一般将来时态
祈使句 含有情态动词

一般现在时态

come (come). I don’t know when hewill _________ I can’t wait here any more. When hecomes _____

(come), would you please ask him to call
me?
