英语句子范文1
一、英语语句基本结构分析:
(一)主谓宾结构:
1、主语:可以作主语的成分有名词(如boy),主格代词(如you),数词,动词不定式,动名词等。主语一般
英语句子结构
在句首。注意名词单数形式常和冠词不分家!
eg: The boy comes from America.
He made a speech.
Tow and tow is four.
To be a teacher is my dream.
Doing a research is a necessary step of covering a story.
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。谓语可以是不及物动词(vi.)没
有宾语,形成主谓结构,
eg:We come.
Many changes took place in my home town.
注(以下这些词是不及物动词:表发生、出现的,如:take place, appear, happen, break out; 表来、去,如:com
e, go 等)
3、宾语:宾语位于及物动词之后,一般同主语构成一样,不同的是构成宾语的代词必须是‘代词宾格’,如:me,
him,them等。除了代词宾格可以作宾语外,名词,动名词,不定式等可以作宾语。
eg:I will do it tomorrow.
The boy needs a pen.
I like swimming.
I like to swim this afternoon.
(二)主系表结构:
1、主语:同‘主谓宾’结构。
2、谓语:联系动词(Link verb):be动词(am,is,are,was,were,have been);其他联系动词如:become成为,turn变
成,go变和感官动词如:feel, touch, hear, see等。其特点是联系动词与其后的表语没有动宾关系,表语多为形容词
或副词,既,不可能是宾语。
3、表语:说明主语的状态、性质、等。可为形容词、副词、名词、代词、不定式、分词。(1)当联系动词不是be,而其后是名词和代词时,多表达‘转变为’之意,注意与动宾关系的区别。
eg: He became a teacher at last.
His face turned red.
(2)感官动词多可用作联系动词
eg: He looks well.他面色好。
It sounds nice.这个听起来不错。
I feel good.我感觉好。
The egg smells bad.这个鸡蛋难闻。
例:Tom is a boy.(Tom是个男孩)主语为Tom,系词为be动词的第三人称单数is,表语为a boy
(三)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:There 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’。
二、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,汉语中常用‘……的’表示。
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。
(一)形容词作定语:
The little boy needs a blue pen.小男孩需要一支蓝色的钢笔。
(二)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。
(三)形容词性物主代词或名词所有格作定语:
His boy needs Tom”s pen.他的男孩需要Tom的钢笔。
There are two boys of Toms there.那儿有Tom家的两个男孩。
(四)介词短语作定语:
The boy in the classroom needs a pen of yours.教室里的男孩需要你的一支钢笔。
The boy in blue is Tom.穿兰色衣服的孩子是汤姆。
There are two boys of 9,and three of 10.有两个9岁的,三个10岁的男孩。
(五)名词作定语:
The boy needs a ball pen.男孩需要一支圆珠笔。
副词作定语:
The boy there needs a pen.那儿的男孩需要一支钢笔。
不定式作定语:
The boy to write this letter needs a pen.写这封信的男孩需要一支钢笔。
(六)分词(短语)作定语:
The smiling boy needs a pen bought by his mother.那个微笑的男孩需要一支他妈妈买的钢笔。
(七)定语从句:
The boy who is reading needs a pen.那个在阅读的男孩需要一支钢笔。
三、状语:状语修饰动词、形容词、副词或全句,说明方式、因果、条件、时间、地点、让步、方向、程度、目
的等
状语在句子中的位置很灵活,常见情况为:通常在句子基本结构之后,强调时放在句首;修饰形容词或副词时,
通常位于被修饰的词之前;表示时间、地点、目的的状语一般位于句子两头,强调时放在句首,地点状语一般须
在时间状语之前;一些表示不确定时间(如:often)或程度(如:almost)的副词状语通常位于be动词、助动
词、情态动词之后,动词之前。
有时状语在句中的某个位置会引起歧义,应注意,如:The boy calls the girl in the classroom.一般理解成‘男孩喊教
室里的女孩‘(此时in the classroom为girl的定语),也可以理解为‘男孩在教室里喊女孩’(此时in the classroom为地
点状语),最好写作‘In the classroom,the boy calls the girl.”
(一)副词(短语)作状语:
The boy needs a pen very much.男孩非常需要一支钢笔。(程度状语)
The boy needs very much the pen bought by his mother.男孩非常需要他母亲买的那支钢笔。(宾语较长则状语前置)
The boy needs a pen now./Now,the boy needs a pen./The boy,now,needs a pen./男孩现在需要一支钢笔。(时间状语)
(二)介词短语作状语:
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 the classroom.星期天,教室里没有学生。(时间状语)
(三)分词(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 needs a pen.因为不得不完成作业,男孩需要一支笔。(原因状语)
(四)不定式作状语:
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)
(五)名词作状语:
Come this way!走这条路!(方向状语)
(六)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
四、直接宾语和间接宾语:
(一)特殊的同源宾语现象: fight a fight , dream a dream , etc.
(二)有些及物动词可以有两个宾语,如:give给,pass递,bring带,show显示。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。
eg: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。eg:Show this house to Mr.Smith.Mr.
五、宾语补足语: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。
(一)名词/代词宾格 + 名词
The war made him a soldier.战争使他成为一名战士。
(二)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。
(三)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。
(四)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。
(五)名词/代词宾格 + 分词
I saw a cat running acrothe road.我看见一只猫跑过了马路。
六、同位语:同位语是在名词或代词之后并列名词或代词对前者加以说明的成分,近乎于后置定语。如:
We students should study hard. (students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’)
七、独立成分:有时句子中会有一些与句子没有语法联系的成分,称为句子独立成分(注意:区别于分词独立结构)。
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。
情态词,表示说话人的语气(多作为修饰全句的状语):perhaps也许,maybe大概,acturely实际上,certainly当然,等。
八、分词独立结构:分词作状语时其逻辑主语与句子的主语一致! 否则应有自己的逻辑主语,构成分词独立结构。
例:错句:Studying hard,your score will go up.
正确:(1) Studying hard,you can make your score go up. 或 (2)If you study hard,your score will go up.
解析:错句中分词studying没有自带逻辑主语,则其逻辑主语就是句子的主语,既your score . 显然做study的应是人,不应是your score(分数)。正确句(1)更正了句子的主语,使其与分词逻辑主语一致( 同为you );正确句(2)则使用条件分句带出study的主语,(不过已经不是分词结构了)。
分词独立结构常省略being,having been.不过‘There being…’的场合不能省略。
如:
Game (being) over,he went home.
He stands there,book (being) in hand.
独立结构还可用with、without引导,作状语或定语。这种结构不但可以用分词,还可以用不定式、形容词、介词短语、副词或名词等。
如:
