英语句子成分结构详解定语| 状语| 宾语| 补语| 同位语| 独立成分| 分词独立结构一、英语语句基本结构分析：>> 主谓宾结构：主语（subject）：可以作主语的成分有名词，主格代词，动词不定式，动名词、主语从句等。

It is very clear that the elephant is round and tall like a tree. （It形式主语，主语从句是真正主语）谓语（predicate）：说明主语的动作、状态和特征。

表语（predicative）:系动词之后的成分，表示主语的性质、状态和特征。

成分：名词、代词、形容词Five and five is ten. （数词）His father is in. （副词）The picture is on the wall. ( 介词短语)My watch is gone / missing / lost. （形容词化的分词）To wear a flower is to say “I’m poor, I can’t buy a ring. （不定式）The question is whether they will come. （表语从句）宾语（object）：1）动作的承受者-----动宾I like China. （名词）He hates you. （代词）How many do you need?

这两个宾语通常一个指人，为间接宾语；一个指物，为直接宾语。

间接宾语一般位于直接宾语之前。

一般的顺序为：动词+ 间接宾语+ 直接宾语。

如：Give me a cup of tea, please.强调间接宾语顺序为：动词+ 直接宾语+ to + 间接宾语。

如：Show this house to Mr. Smith.若直接宾语为人称代词：动词+ 代词直接宾语+ to + 间接宾语。

如：Bring it to me, please.>>>特殊的同源宾语现象cognate object : fight a fight , dream a dream , etc.宾语补足语（object complement）：位于宾语之后对宾语作出说明的成分。

宾语与其补足语有逻辑上的主谓关系，它们一起构成复合宾语。

名词/代词宾格+ 名词The war made him a soldier./战争使他成为一名战士.名词/代词宾格+ 形容词New methods make the job easy./新方法使这项工作变得轻松.名词/代词宾格+ 介词短语I often find him at work./我经常发现他在工作.名词/代词宾格+ 动词不定式The teacher ask the students to close the windows./老师让学生们关上窗户.名词/代词宾格+ 分词I saw a cat running across the road./我看见一只猫跑过了马路.主补（subjective complement）：充当补充主语的作用。

1. 形容词作主语补足语时常置于主语之前，后有逗号。

Tired and sleepy, he went to bed.有时亦可置于主语之后，前后皆有逗号，与非限定性定语相似。

Their chief, cruel beyond belief, didn’t listen to their pleadings有时置于谓语动词之后，全句形成“主+谓+主补”结构。

Mary gaped round-eyed.有时亦可置于宾语之后，全句形成“主+谓+宾+主补”He got off the bus very nervous.His mother stared at him speechless.2. 可用作主语补足语的词：形容词、名词、数词、不定式、分词、介词短语等。

He was called David Copperfield.Lincoln was born a poor family’s boy and died President of the United States.She came home quite changed.People are just born what color they are.Mary came home out of humour.同位语（appositive）：当两个指同一事物的句子成分放在同等位置时，一个句子成分可被用来说明或解释另一个句子成分，前者就叫做后者的同位语。

同位语通常放在其所说明的名词之后。

如：Laura Myers, a BBC reporter, asked for an interview. 劳拉·迈尔，BBC的记者，要求采访。

Influenza, a common disease, has no cure. 流行性感冒是一种常见病，无特效药。

1. 代词we, us, you等后接同位语Are you two reading? 你们二人在看书吗?We girls often go to the movies together. 我们女孩子经常一起去看电影。

2. 不定式用作同位语Soon came the order to start the general attack. 很快下达了发起总攻的命令。

(to start the general attack与the order同位)He followed the instruction to walk along a certain street where I picked him up. 他照吩咐沿某一条街走，我在那里接他上了车。

(to walk along…与the instruction同位)3. -ing分词用作同位语He’s getting a job tonight driving a truck. 他今晚得到一个开卡车的差事。

(driving a track与a job 同位)She got a place in a laundry ironing shirts. 她在一家洗衣店得到一个熨衣服的职位。

(ironing shirts 与a place同位)The first plan, attacking at night, was turned down. 第一个计划是夜袭，被拒绝了。

(attacking at night 与the first plan同位)4. none of us之类的结构用作同位语We none of us said anything. 我们谁也没说话。

They neither of them wanted to go. 他们两人都不想去。

【注】注意，同位语并不影响其后句子谓语的“数”，如：学生每人都有一本词典。

正：The students each have a dictionary.误：The students each has a dictionary.请比较下面一句（谓语用了单数，因为each为句子主语）：正：Each of the students has a dictionary.5. 从句用作同位语（即同位语从句）They were worried over the fact that you were sick. 他们为你生病发愁。

The news that we are having a holiday tomorrow is not true. 明天放假的消息不实。

The idea that you can do this work without thinking is wrong. 你可以不动脑筋做此工作的想法是错误的。

6. 同位语与其所说明的名词之间常插入一些词语，常见的有namely, that is to say, in other words, or rather, for short, for example, particularly, say, mainly等I am pleased with only one boy, namely, Tom.同位语与主语补足语不同，前者强调等同，意在说明或解释，主语补足语则弥补主语意义之不足，有表述主语的性质。

定语（attributive）：定语是对名词或代词起修饰、限定作用的词、短语或句子，定语通常位于被修饰的成分前。

若修饰some, any, every, no构成的复合不定代词时，（如：something、nothing）或不定式、分词短语作定语、从句作定语时，则定语通常置后。

副词用作定语时须放在名词之后。

形容词作定语：｛定语置前｝The little boy needs a blue pen.(little修饰名词boy；blue修饰名词pen.）/小男孩需要一支兰色的钢笔。

Tom is a handsome boy./Tom是个英俊的男孩。

数词作定语相当于形容词：Two boys need two pens./两个男孩需要两支钢笔。

There are two boys in the room./房间里有两个男孩。

代词或名词所有格作定语：｛定语置前｝His name is Tom./他的名字是汤姆。

名词作定语：｛定语置前｝The boy needs a ball pen./男孩需要一支圆珠笔。

介词短语作定语：｛定语置后｝The boy in blue is Tom./穿兰色衣服的孩子是汤姆。
