组成句子的各个部分叫句子成分。
英语句子成分有主语,谓语,宾语,表语,定语,状语,补语(宾语补足语和主语补足语)和同位语。 其中主语,谓语,宾语是句子的主要成分,其余的均为次要成分。
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
名词或从句作主语
名词---名词或名词短语或名词化形容词或名词化分词作主语 Beijing will be rainy. 北京将多雨
Weather in our coastal city is nice and cool in summer 夏季我们沿海城市的天气舒适,凉爽 Old and young marched side by side 老少并肩而行
The wounded should be sent to hospital at once受伤人员应立即送往医院
代词—He told a joke but it fell flat. 他说了个笑话,但没引人发笑。 Who is the man in the car 汽车里的人是谁
数词—Three is enough for each of us.三个对于我们每个人来说就足够了 One of my classmates is from Australia.我的一个同学是澳大利亚人
不定式—动词不定式或不定式短语(动词不定式后面可以有自己的宾语和状语。动词不定式和它的宾语或状语构成不定式短语)
To become a player like Yao Ming is my wish.成为像姚明一样的运动员是我的心愿。 ---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 It is my wish to become a player like Yao Ming.
It would be nice to see him again.如能见到他,那将是一件愉快的事。
动名词(动词的ING形式)作主语 Smoking is bad for you.
从句作主语---作主语的从句称为主语从句,可由that whether wh-词等引导。 Whenever you are ready will be fine.你无论什么时候准备好都行。
That she forgot to tell me the time for the meeting caused lots of trouble.她忘了告诉我开会的时间,这给我带来了很多麻烦。
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成分。 (主语与谓语在人称与数方面要相互照应)
表语--- 常用的连系动词有:be, look, get, sound, feel, become, smell, turn, taste等
名词作表语
She is an ordinary teacher. 她是一个普通的老师
He turned doctor after school, as his parents had expected.正如父母所愿,毕业后他成了医生。
代词作表语

名词的-ing形式和-ed形式作表语

介词短语作表语

动词不定式或短语作表语 To see is to believe.眼见为实
副词及其短语作表语 Is anybody in 有人在吗
补语:
宾语补足语-----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:告诉 tell 让let 帮助help 教teach 问ask 看见see 有have 命令order 使make,等 Don’t keep the lights burning. 不要让灯开着。
The doctor told me to do more exercise.医生告诉我多做练习。 We will make them happy.我们会让他们高兴的。
主语补足语即被动语态中的宾语补足语 举个例子
They caught boy stealing.
boy是caught的宾语,stealing是boy的状态,宾语补足语
把它变成被动语态The boy was caught stealing,此时stealing就成了主语补足语 再来看几句主语补足语的句子 The dog is called Karl The door was painted white.
The glass was found broken. 这些都是。
同位语---Mr Wang, our new teacher, is very kind to us.
Yesterday I met Jim, a friend of my brother’s.昨天我遇到了我弟弟的一个朋友吉
姆。
如同位语与其同位成分关系密切时不用逗点隔开;如同位语对其同位成分只作补充解释时可用逗点隔开。
He told me that his uncle John is a world-famous doctor.他对我讲,他的叔叔约翰是一位世界闻名的医生。
He has read all kinds of books, ancient and modern, Chinese and foreign.他看了各种各样的书,古今中外都有。
同位语除表示其同位成分的全部意义外,还可以表示部分意义。
We Chinese people are brave and hard-working.我们中国人民是勤劳勇敢的。 全部意义
Amy is interested in sports, especially ball games.艾米喜欢运动,特别是球类运动。部分意义
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。可用作独立成分的通常有3种词语,即感叹语,呼语和插入语。
What is it, do you think 你认为这是什么呢 插入语
Come in and take a seat, Mr Li.李先生,请进来坐。 呼语 Hello! How are you嘿,你好 感叹语
简单句的五种基本句型
主谓 主谓宾 主谓表 主谓双宾 主谓宾宾补
1.主谓—Robert sings in the next room.罗伯特在隔壁唱歌
Yuan Longping works very hard.袁隆平工作很努力 这种句型中的动词大多是不及物动词,所谓不及物动词,就是这种动词后不可以直接接宾语。
2.主谓宾—We like English.
Wang Gang always helps me when I have difficulties.当我遇到困难时,王刚总能给我帮助。 这种句型中的动词一般为及物动词,所谓及物动词,就是这种动词后可以直接接宾语。
3.主谓表—谓语用连系动词。常用的连系动词有:be是, look看起来, get, sound听起来, feel, become, smell闻起来, turn, taste尝起来,keep保持, seem好像, 等 He seemed an honest man.他似乎是个诚实的人。
刚才刘翔看上去有些焦急。Liu Xiang looked worried just now.
4.主谓双宾----双宾是指间接宾语和直接宾语。这种句型中,直接宾语为主要宾语,表示动
作是对谁做的,在句中不可或缺,常常由表示“物”的名词来充当,间接宾语也被称之为第二宾语,去掉之后,对整个句子的影响不大,多由指“人”的名词或代词承担。引导双宾语的常见动词有: buy买, teach教, lend借给, give给, tell告诉, pass传递, show出示, bring带来, send发送.
Her father bought her a book=Her father bought a book for her.他爸爸给她买了一本书。

句子结构
按照句子的结构划分,英语有简单句,并列句和复合句。 简单句
五种基本句型都是简单句
并列句
并列句是由并列连词and,but,or,for,so等把两个或两个以上互不依从,但意思紧密联系的简单句连在一起而构成的句子。其结构为简单句+并列连词+简单句
表示同等关系的并列句 and
;Last year I met Ann and we became friends.
表示转折关系的并列句
常用并列连词but但是,yet可是,while而,另一方面,however可是 It has no month, but it can talk.它没有嘴巴,但是它会说话。
He wants to be a writer, while I want to be a doctor.他想当作家,而我则想当医生。
表示选择关系的并列句
“或者”Now you can have a rest or you can watch TV.
“否则,要不然” Take the chance, or else you’ll regret it.抓住机会,否则你会后悔的。
表示因果关系的并列句for so
For在意义上与从属连词because,since和as相同,但它们引导的是原因状语从句,而for则连接两个简单句,前者表示结果,后者表示原因。 You’d better take un umbrella, for it is going to rain. So意为“因此”“所以”,但不能与because同时出现在同一个句子中。因为because是从属连词,而so是并列连词,用来连接并列句。
Mr Zhao went to his hometown, so Mr Wang was taking his class instead.赵老师回家乡去了,所以王老师替他上课。
其他形式的并列句 “不是。。。就是。。。, 或者。。。或者。。。”either…or…
Either my father can do it, or my mother can do it. (=Either my father or my mother can do it.)我爸爸可以做那件事,或者我妈妈也可以做。
not only…but also…(Not only the students have missed the school car, but also the teacher has missed the school car.)不仅学生,而且他们的老师都误了校车。
复合句

当主句中的谓语动词是think,say,guess,suppose,suggest,believe,feel等时,宾语从句的引导词常是who,which,what,when,where,how,why 等疑问词,经常将此类引导词置于句首。 Who do you think the public might choose as their favorite singer this year 你认为今年公众会选谁为他们最喜欢的歌手
