一、句子的成分:
在英文中句子成分包括:主语、谓语、表语、宾语(直接宾语、间接宾语)、宾语补足语、定语和状语等.
(一)主语:主语是谓语讲述的对象,表示所说的“是什么”或“是谁”.一般由名词、代词、不定式或相当于名词的词或短语来充当.它在句首.如:
(1)Comrade Chen is a well-known scientist.
陈同志是著名的科学家.(名词作主语)
(2)He reads newspapers every day.

(3)Smoking isharmful to the health.

(4)To swim in Kunming Lake is a great pleasure.

(5)What we shall do next is not yet decided.
下一步我们做什么还没定下来.(主语从句作主语)
(二)谓语
说明主语“做什么”“是什么”或“怎么样”.谓语(谓语部分里主要的词)必须是动词.谓语和主语在人称和数两方面必须一致.它在主语后面.
如:His parents are teachers.
(系动词和表语一起作谓语)

(行为动词作谓语)

(助动词和行为动词一起作谓语)
He can speak English.
(情态动词和行为动词一起作谓语)
(三)宾语
宾语是动作、行为的对象,由名词、代词、不定式或相当于名词的词、短语来担任,它和及物动词一起说明主语做什么.一般放在谓语之后.
She is doing her homework now.(名词作宾语)
She said(that)she felt sick.(宾语从句作动词宾语)
We often help him.(代词作宾语)
He likes to play basketball.(不定式作宾语)
We enjoy listening to the music.
我们喜欢听音乐.(动名词短语作宾语)
说明1:宾语是及物动词涉及到的人或物,宾语一般放在及物动词之后.介词后面的名词或代词或动名词,称为介词宾语.名词、代词、数词常在句中做动词宾语或介词宾语.另外,动词不定式可作动词宾语;动名词和宾语从句也可用作动词宾语.
说明2:及物动词作谓语时,后面要跟宾语.宾语分直接宾语和间接宾语.直接宾语是及物动词的直接对象,直接宾语指物,间接宾语通常是及物动词的动作所及的人,间接宾语指人.间接宾语一般放在直接宾语之前.
不是所有的及物动词都可以用双宾语.有的动词可以跟.如:give,show(给……看),bring,pass, buy等.如:
(1)Our teacher told us a story.
(us为间接宾语,a story为直接宾语.)
(2)The sun gives us light and warmth.
(us为间接宾语,lightand warmth为直接宾语)
(3)We sent him atelegram.
我们给他打了电报.
(him为间接宾语,a telegram为直接宾语)
间接宾语如果放在直接宾语之后,在表示“人”的间接宾语之前会出现介词“to”或“for”.在这种情况下,间接宾语前加“to”的有:
give, show, send, bring, read, pass, lend, leave(留给), hand(交给), tell, return, write, throw(扔), promise(答应), refuse(拒绝)等.
加“for”的有:make, buy, do, get, play(演奏), order(命令), sing, pay(为……交钱)
例如:(1)I gave him a book.
改成:I gave a book to him.
(2)He passed me the book.(他将书递给我.)
改成:He passed the book to me.
(3)He wrote me a letter.
改成:He wrote a letter to me.
(4)He will buy me some books.
改成:He will buy some books for me.
(5)She made me a cake.
改成:She made a cake for me.
(四)宾语补足语
在某些及物动词后面,需要用一个宾语再加一个宾语的补语才能表达完整的意思.在宾语后面补充说明宾语的动作、状态、特征的成分,称为宾语补足语.名词、形容词、副词、介词短语以及动词不定式、分词等可用作宾语补足语.宾语和宾语补足语称为复合宾语.
如:They made her happy.(形容词)
Isaw her dance.(不定式)
We’ll help make the Olympics a success.(名词)
Please let him in.(副词)
We heard her singing a song.(分词短语)
(五)表语
表语说明主语“是什么”或者“怎么样”,由名词、形容词、副词、介词、不定式及相当于名词或形容词或短语来担任.它的位置在系动词后面.
如:I am a teacher.(名词)
He is always happy.(形容词)
They are on the playground now.(介词短语)
It gets cold.(形容词)
系动词除了有am,is,are还有get(变得),sound(听起来),seem(看起来),feel等特殊的词.
如:It sounds interesting.(sound为系动词,interesting为表语)
(六)定语
定语是用来修饰名词或代词的.形容词、代词、数词、名词、介词短语、不等式或相当于形容词的词或短语等.
单词作定语时,通常放在它所修饰的名词之前.
如:The black bike is mine.(形容词)
这辆黑色的自行车是我的.
What’s your name?(代词)
They made paper flowers.(名词)
说明1:当定语修饰不定代词,如:nothing,anything, everything, something等时,定语要放在其后作后置定语.
如:I tell him something interesting.
我告诉他一些有趣的事情.
(形容词interesting作不定代词something的后置定语)
He has something to do.
他有一些事情去做.(to do为不定式作后置定语)
说明2:短语或从句作定语时,也放在被修饰的名词之后.
如:The boys in the room are in Class Four.
这间屋子里的男孩子们是4班的.
in the room是介词短语作the boys的后置定语.
(七)状语
修饰动词、形容词、副词.一般表示行为发生的时间、地点、目的、方式、程度等意义,一般由副词、介词短语、不定式或相当于副词的词或短语来表示.状语一般放在句末,但有的可以放在句首、句中.
如:He did it carefully.(副词)
We often help him.(副词)
Her mother goes out to do some shopping onSunday.(介词短语)
When I grow up, I am going to be a teacher.(从句作时间状语)
He sat there.(副词地点状语)
二. 简单句的五种基本句型
简单句有五种基本句型:
A. 主语+不及物动词
如:The sun rises.
太阳升起来.
The car stopped.
小汽车停下来了.
rise和stop都是不及物动词,因此后边不必加宾语.
B. 主语+及物动词+宾语
如:I love my country.
He helped me.
Ilike action movies.
Ibought a book.
C. 主语+系动词+表语
Her brother is a driver.
We feel happy.(feel为系动词,表示感到……)
It gets dark.天黑了.(get为系动词,表示变得)
Tom looks ill. Tom看上去病了.
(look为系动词,表示看上去)
D. 主语+及物动词+双宾语(直接宾语、间接宾语)
He gave Tom a present.(双宾语)
他给汤姆一件礼物.
Mother made a new dress for me.(双宾语)
妈妈为我做了一件衣服.
E. 主语+及物动词+宾语+宾语补足语

我们使我们的教室干净而整齐.
He always makes us laugh.(宾补)

及物动词和不及物动词之
秘诀一 、及物动词后面直接加宾语,不及物动词后是不能直接加宾语,但有些不及物动词后面加介词或副词之后就可以加宾语了(例如:look 是典型的不及物动词,后面是不能接宾语的,但是如果加上适当的介词就可以跟宾语如look at the blackboard 、look for the child 、lokk after his mother等等).
秘诀二、 及物动词后面必须加宾语,因为不加宾语,句意就不完整了.
秘诀三、 绝大多数动词既可以作及物动词也可以作不及物动词 ,只作及物动词或不及物动词的动词是很少一部分.
结合上边的介绍,大家想想看,主谓结构里的谓语动词应该是及物动词还是不及物动词?很明显是不及物动词,因为动词后边没有宾语.
主谓结构,我们要注意的是,虽然这个结构中动词后边不加宾语,但是往往带有状语,现在你第二次遭遇到状语了那么状语究竟是什么呢?状语的确有点难理解,但是他在句子中是经常出现的(除非这个句子是超短句,有三四个单词组成),请大家看下面的句子:
请各位注意:下划横线的单词,就是状语,
1. He will come tomorrow.(他明天来)
2. He is working now .(他正在工作).
3. He works at this factory .(他在这个工厂工作)
4.He often swims in the river.(他经常在河里面游泳)
5.Tom is always late for school.(汤姆经常上学迟到)
6.I have never been to Shanghai.(我从没去过上海)
7.My Chinese is very good . (我的汉语非常好)
8.He runs quite fast. (他跑的相当快)
9.He works hard. (他努力工作)
10.It is too hot . (天气太热了)
