初中英语句子成份
英语句子与汉语句子一样，都是由单词按照一定的规则所组成的。不同的词类在句中所起的作用是不同的。因此，只有搞清不同词类在句中可充当哪些成分，才能正确分析、理解句子的含义，并能准确地遣词造句，逐渐达到流利地说出地道的英语。
【问】什么是句子成分？英语句子包含哪些成分？
【答】组成句子的各个部分叫做句子成分。它包括：主语、谓语、宾语、定语、状语、表语和宾语补足语等。
【问】各成分在句中的作用如何？分别由哪些词及短语充当？
1.主语：是句子要说明的人或事物，是句子的主体，一般由名词、代词、数词、不定式或动名词等充当。如：
? The car is running fast. / The girl can sing many English songs.(名词)
? We are students. / This is my pen . Yours is on the desk.(代词)
? One of my classmates is from Shanghai. / Two and three is finve.(数词)
? The blind need more help.(名词化的形容词)
? It's bad manners to spit in public. (不定式)
? Eating too much is bad for your health.(动名词)
? 【注意】若不定式短语作主语常用it作形式主语，而把真正的主语(不定式短语)放
在句后。
.2.谓语：说明主语的动作或状态，也是句子的主体部分，一般由动词充当。动词分为实义动词、连系动词、情态动词和助动词。实义动词单独作谓语，连系动词与表语一起构成谓语，情态动词与省略to的不定式构成合成谓语，助动词与动词原形共同构成谓语部分。如： ? 由单一动词作谓语：We are Chinese. / He has an English- Chinese dictionary.
? 情态动词加主要动词：We can play the piano. / You must see the doctor.
? 助动词加主要动词构成谓语：She is talking with her sister. / I have seen this man before.
【注意】谓语与主语在人称与数方面要相互照应。
3.表语：用于说明主语的身份、特征或感受，一般由名词、数词、形容词、分词等充当。常用的连系动词有：be，look，get，sound(听起来)，feel，become， smell，turn，taste(尝起来)等。如：
? They are workers.(名词)
? Two and three is five.(数词)
? The story is very interesting.(形容词)
? M y job(工作)is teaching English.(动名词)
? She is at home.(介词短语)
? I feel terrible.(形容词)
? The dish tastes delicious.(形容词)
? He is here (副词)
? It?s getting dark. / He got very angry. / The hill has turned green. (形容词)
4, 宾语：是及物动词所涉及的对象，是动作的对象或承受者。一般由名词、代词、不定式及动名词等充当。如：
? He is doing his homework. / I saw a plane in the sky just now. (名词)
? They did nothing this morning. / I met him on my way home.(代词)
? I want three./ Please pass me the first. (数词)
? She wants to go home.(不定式)
? We enjoy playing football.(动名词)
? 【注意】①有的动词可接双宾语，间接宾语指人，直接宾语指物。这类动词常见的
有：give，buy，lend，pass， tell，leave等。如：
? He bought me a book.
? Pass me the ball，will you？(间宾＋直宾)
? 直接宾语一般放在间接宾语之后，但若把直接宾语放在前面，则要在间接宾语前加
适当的介词如to或 for等。如：
? Han Chen lent some money to Li Hai.(直宾＋间宾)
? Xiao Liu bought a dictionary for Tom.(直宾＋间宾)
? ②有的动词常用不定式作宾语，而不能用动名词。这类动词有：want，wish， hope，
promise，decide，agree， choose，care等。如：
? I hope to see you again.
? ③有的动词一般只用动名词作宾语，而不用不定式。这类动词有：enjoy，finish，
mind，practise，miss， suggest，keep(on)等。如：
? Do you mind my opening the window？
? ④有的动词后接不定式与动名词含义不同。
? a)forget to do表示“未发生的动作”，forget doing表示“已完成的动作”。如： ? Don't forget to come here earlier tomorrow.(还没来)
? I forgot returning the book to him.(书已还给他了)
? b)stop to do(不定式为状语)表示“停下
? 原来的事，去做另一件事”，stop doing表示“停止做某事”。如：
? I stopped to talk with him.(我停下来与他谈话。)
? The students stopped talking when the teacher came in.(老师进来时学生们停止谈话。 ? 注意：英语中带有宾语的谓语动词叫及物动词，不带宾语的叫不及物动词。及物动
词后必须跟上宾语意义才完整，不及物动词本身意义已完整，后面不跟宾语。 ? You may use my pen. / Do you like fish? ( 及物)
? Dick swims very well. / The sun rises in the east. (不及物)
? 不及物动词可加介词再加宾语
? We are listening to the music.
? They are talking to each other.
既可以作及物动词又可以作不及物动词的词：
? We are growing tomatoes. / Tomatoes grow well in our garden.
? They left Shanghai yesterday. / They left yesterday.
? My mother teaches in this school. / She teaches English.
? We are studying. / We study English.
? We began our lesson at nine. / The lecture began at nine.
5. 直接宾语与间接宾语。
? 有些及物动词可带有两个宾语，其中一个指物（直接宾语），另一个指人（间接宾语）。
我们称为双宾语。
? 动词+间接宾语（人）+直接宾语（物）
He lent me a book. / He bought me a pen. / I have taught myself English for ten years. ? 动词+直接宾语（物）+（to,for）+间接宾语（人）
He gave his son some advice. = He gave some advice to his son.
Father bought me a computer. = Father bought a computer for me.
6. 定语：用于修饰名词或代词，一般由形容词、名词、数词、不定式等充当。如：
? What a beautiful kite it is！/ They have a clever son.(形容词)
? She is a chemistry teacher. / It is a colour film.(名词)
? There are two students in the classroom.(数词)
? This song is better than that one. (代词)
? Do you know the young man over there? (副词)
? We have something to do tomorrow.(不定式)
? The man in blue is my brother.(介词短语)
? 【注意】定语一般位于被修饰词之前，但若修饰不定代词或不定式等短语作定语，
则放在后面。
7. 状语：用于修饰动词、形容词、副词或全句，一般由副词、介词短语、不定式短语或从句充当。单个副词作状语一般放在被修饰词之前，短语或从句放在句首或句末。如：
? Thank you very much.(副词表示程度)
? The old man is walking slowly. (副词表示方式)
? He usually gets up at six.(副词表示时间)
? We all wouk here. (副词表示地点)
? I get up at five in the morning.(介词短语表示时间)
? He is studying hard so as to catch up with others.(不定式短语)
? We were having breakfast when the telephone rang.(从句)
? 【注意】enough作状语只能放在被修饰词之后。如：
? He is old enough to go to school.
8. 宾语补足语：用于补充说明宾语的动作，一般位于宾语之后，宾语与宾语补足语一起构成复合宾语。需接复合宾语的动词有：tell，let，help，teach， ask，see，have，order，make等。“宾补”一般由不定式短语、分词、名词、形容词等充当。如：
? We elected him monitor. / (名词)
? I found it difficult to learn English well. / The sun keeps us warm./ We find the story very
interestingh. (形容词)
? I found her in the room.(介词短语)
? Please let him in. / I saw him out with XiaoLi. (副词)

由一个从句在句子中作宾语，这个句子就叫宾语从句。
For example:
1. I know she lives here.
2. Father is thinking of how we can get to the station?
3. I am sorry that I am late for class.
.宾语从句的连接词有三种形
由that引导；
2.由连接代词who,what,which,whose和连接副词when,where,why how等引导；
3.由if 或whether引导。
1.当宾语从句是由陈述句变化而来的时候，该从句通常由that引导。That无具体意义，不作任何成分，因此在口语或者非正式文体中常常被省略。For example.
We all say. Lao Wang is a good friend.
We all say (that)Lao Wang is a good friend.
I ?sure. You have seen that book before.
I ?m sure(that)you have seen that book before.
? Exercise:
?
?
? 1. He said ____ everyone was here except LinFeng. a, that b, what c, when d, where 2. My friend says. He is a teacher. (变成宾语从句）
My friend (that) he is a teacher
2.当宾语从句由一般疑问句变来时， 须用连词if 或者Whether引导，意思为“是否”，表示选择。For example:
1）.Could you tell us? will he ready come here?
Could you tell us if (whether) he will really come here?
Is the Summer Palace open now? could you tell me?
Could you tell me if (whether) the Summer Palace is open now.
思考：
I f 和whether在引导宾语次从句时有区别吗？如果有，请说出它们的区别
.当宾语从句由特殊疑问句变来时，则用连接代词who, Whose, what, which和连接副词when, where, why, how等引导。它们均是充当一定成分，一般不可省略。For example: Could you tell me?where is the nearest post office?
Could you tell me where the nearest post office is?
注意：
连接词与其后名词构成短语时则不可拆开使用。
For example: what time, which room, how many people.等。
For example: please tell me how many pictures they?ve drawn
recently.
