1、句 子 成 分Members of a Sentence*句子成分由词或词组充当 英语的基本成分有七种：_和_ 主语（subject）、谓语（predicate）、表语（predicative）、宾语（object）、定语（attribute）、状语(adverbial)补语（complement）。英语句子的基本结构可以归纳成五种基本句型及其扩大、组合、省略或倒装。掌握这五种基本句型，是掌握各种英语句子结构的基础。一：（主谓）二：（主系表）三：（主谓宾）四：（主谓间宾直宾）五：（主谓宾宾补）基本句型 一：（主谓）主语：可以作主语的成分有名词，主格代词，动词不定式，动名词等等。主语一般在句首。
2、谓语：谓语由动词构成，是英语时态、语态变化的主角，一般在主语之后。不及物动词（vi.）没有宾语，形成主谓结构，如：We come.（不及物动词）1.The sunrose.2.Who cares?3.What he said does not matter.4.They talked for half an hour.5.The pen writes smoothly此句型的句子有一个共同特点，即句子的谓语动词都能表达完整的意思。这类动词叫做不及物动词，后面可以跟副词、介词短语、状语从句等。基本句型 二：（主系表）此句型的句子有一个共同的特点：句子谓语动词都不能表达一个完整的意思，必须加上一个
3、表明主语身份或状态的表语构成复合谓语，才能表达完整的意思。这类动词叫做连系动词。1.表感官的系动词：look,sound,taste,smell,feel（这些词用形容词作表语）2.表似乎的系动词seem,appear 3.表变化的系动词：become,get,turn,grow,make,come,go,fall,run 4.表依旧的系动词：remain,keep,stay,continue,stand,rest,lie,hold 5.可带名词作表语的系动词：become,make,look,sound,fall,prove,remain,turn（该词后接的单数名词前多不用冠词。如：He
4、turned teacher.）（是系动词）（表语）1.This is an English-Chinese dictionary.2.The dinner smells good.3.He fell in love.4.Everything looks different.5.He is growing tall and strong.6.Our well has gone dry.7.His face turned red.*There be 结构：There be 表示存在有。这里的there没有实际意义，不可与副词there那里混淆。此结构后跟名词，表示（存在）有某事物试比较：Ther
5、e is a boy there.（那儿有一个男孩。）前一个there无实意，后一个there为副词那里。基本句型 三：（主谓宾）此句型句子的共同特点是：谓语动词都具有实义，都是主语产生的动作，但不能表达完整的意思，必须跟有一个宾语，即动作的承受者，才能使意思完整。这类动词叫做及物动词。（及物动词）（宾语）1.Who knows the answer?2.He has refused to help them.3.He enjoys reading.4.He said Good morning.5.He admits that he was mistaken.基本句型 四：（主谓间宾直宾）有
6、些 及 物 动 词 可 以 有 两 个 宾 语，eg：give/pass/bring/show。这两个宾语通常一个指人(间接宾语)；一个指物(直接宾语)。-Give me a cup of tea please.-Show this house to Mr.Smith.-Bring it to me,please.（及物）（多指人）（多指物）1.She ordered herself a new dress.2.He brought you a dictionary.3.I showed him my pictures.4.I told him that the bus was late.5.
7、He showed me how to run the machine.基本句型 五：（主谓宾宾补）此句型的句子的共同特点是：动词虽然是及物动词，但是只跟一个宾语还不能表达完整的意思，必须加上一个补充成分来补足宾语，才能使意思完整。宾语补足语：位于宾语之后对宾语作出说明的成分。可以用作宾语补足语的有名词，形容词，不定式，动名词，分词，介词短语等。The war made him a soldier.New methods make the job easy.I often find him at work.The teacher ask the students to close the wi
8、ndows.I saw a cat running across the road.名词/代词宾格+n./adj./介词短语/动词不定式/分词（及物）（宾语）（宾补）1.They painted the door green.2.This set them thinking.3.They found the house deserted.4.He asked me to come back soon.5.I saw them getting on the bus.a，b，c，d，e，1，Pleas tell us a story._2,She smiled._3.I have a lot wo
9、rk to do._4.His job is to train swimmers._5.He noticed a man enter the room._6.Please look at the picture._daebec但常用的英语句子并不都象基本句型这样简短，除了基本句型的成分不变外，通常是在这些成分的前面或后面增加一些修饰语而加以扩大。这些修饰语可以是单词（adj./adv./num.数词）短语（主要是介词短语、不定式短语和分词短语）。我们称之为：定语、状语The little boy needs a blue pen.一、定语：定语是对名词或代词起修饰、限定作用的词、短语或句子，译
10、为的定语通常位于被修饰的成分前。复合不定代词（something/nothing）之后；不定式/分词短语/从句作定语时要放在被修饰的成分后；副词用作定语时须放在名词之后。Two boys need two pens.His name is Tom.The boy in blue is Tom.The boy there needs a pen.The boy needs a ball pen.There is nothing to do today.The pen bought by her is made in China.The boy you will know is Tom.二、状语：
11、状语修饰动词、形容词、副词或全句的句子成分，说明方式、因果、条件、时间、地点、让步、方向、程度、目的等-The boy needs a pen now.-The boy needs a pen very much.可用作状语的有副词,不定式，分词，介词短语，从句等。In the classroom,the boy needs a pen.在教室里，男孩需要一支钢笔。（地点状语）Before his mother,Tom is always a boy.在母亲面前,汤姆总是一个男孩子.(条件状语)On Sundays,there is no student in theclassroom.星期天
12、,教室里没有学生.(时间状语)介词短语作状语：He sits there,asking for a pen.他坐在那儿要一支笔。（表示伴随状态）Having to finish his homework,the boy needsa pen.因为不得不完成作业，男孩需要一支笔。（原因状语）Frightened,he sits there soundlessly.（因为）受了惊吓，他无声地坐在那儿。（原因状语）分词（短语）作状语：The boy needs a pen to do his homework.男孩需要一支笔写家庭作业。（目的状语）To make his dream come tru
13、e,Tom becomesvery interested in business.为实现梦想,汤姆变得对商业很有兴趣.不定式作状语：状语从句：时间状语从句、地点状语从句、原因状语从句、结果状语从句、目的状语从句、比较状语从句、让步状语从句、条件状语从句-We chatted as we walked along.-Even if she laughs at him,he adores her.三、同位语：同位语 当两个指同一事物的句子成分放在同等位置时，一个句子成分用来说明和解释另一个句子成分，这个句子成分就叫做它的同位语。We students should study hard.(stud
14、ents是we的同位语，都是指同一批学生）We all are students.(all是we的同位语，都指同样的我们）四、独立成分：与全句没有语法关系的句子成分叫做句子的独立成分感叹词：oh,hello,aha,ah,等。肯定词:yes否定词:no称呼语：称呼人的用语。插入语：一些句中插入的 I think,I believe,等。如:The story,I think,has never come to the end.我相信,这个故事还远没结束.一)挑出下列句中的宾语 My brother hasnt done his homework.People all over the worl
