句子是按照一定的语法规律组成的,表达一个完整的意义。一个句子一般由两部分构成,即主语部分和谓语部分,这两部分也叫做句子的主要成分。句子的次要成分包括宾语,定语,状语,表语等。句子成分是句子中起一定功用的组成部分。
1)主语:是一句的主体,是全句述说的对象,常用名词,数词或代词担任,一般放于句首。如:
Students study. (学生学习。)
We are friends.(我们是朋友)
这两句话中单词students是个名词,we是代词,它们在句中做主语。
2)谓语:是对主语加以陈述,表示主语的行为或状态,常用动词或者动词词组担任,放在主语的后面。如:
Students study. (学生学习。)
We are friends. (我们是朋友)
这两句话中单词study和are都是动词,study叫做实意动词,are叫做be动词,它们在句中作谓语。
3)宾语:表示行为的对象,常由名词或者代词担任。放在及物动词或者介词之后。如:
They are teachers. ( 他们是老师。)
I play with him. (我和他一起玩。)
这两句话中单词teachers是名词,单词him是带词,它们在句中作宾语。
4)定语:是用来说明或者限制名词的成分,常用形容词或者相当于形容词的短语或从句担任。形容词放在名词之前,相当于形容词的短语或从句放在名词的后面。如:
This is a red sun.(这是个红太阳.)
He is a tall boy.(他是个高个子男孩。)
这两句话中单词red和 tall都是形容词,它们作定语。
5)状语是用来说明动词,形容词,副词或整个句子的成分。常由副词担任。修饰动词时可以放在动词之前,也可以放在动词之后;修饰形容词或副词时放在它们之前。如:
The students study hard. (这些学生学习努力。)
I often write to him. (我常给他写信。)
The bag is too heavy. (这个书包太重了。)
这三句话中单词hard 和often修饰的都是动词,第三句话中单词too修饰的是形容词,它们都作状语。
6)表语:用来说明主语的性质或状态。一般由名词或者形容词担任。如:This table is long. (这个桌子是长的。)
通常情况下,主语和宾语前的成分是定语,谓语前的成分是状语,时间词作状语放在句子后面。句子的成分分布如下:
(定语) 主语 (状语) 谓语 (定语) 宾语 (状语)
如:(The tall) boy (often) go (to the big) zoo.
(The happy) child --- went (his) home yesterday.
请分析下面句子的结构说出各个成分
1)I have two elder sisters. (我有两个姐姐。)
2) They don't swim very well.(他们游泳不太好。)
3) Do you go to school every day? (你每天去上学吗?)
4) I really want a cup of tea.(我真的想要一杯茶。)
5) Miss Smith teaches English very well.(史密斯先生教英语非常好。)
语法其实并没有一些人想象的那么可怕,其实里面有很多趣味。
第一讲 英语句子成分
WARM-UP:1)The teacher in the classroom. 2)Sang many songs and danced happily. 3)She attracts. 4)Many people living in the country. 5)All the books on the desk over there.
以上这些形式都不能构成英语句子。
英语句子(sentence)=主语 谓语(核心:主动词)

英语句子八呀八大块, 主谓宾表真呀真实在;
补语跟着宾语表语跑, 定语同位(语)专把名词踹。
状语的位置它自由自在, 忽右忽左随心所欲摆。
浑身的毛病真呀真不少, 前后乱窜它还会加塞。(RAP)

II.成分关系
1.补语跟着宾语表语跑:
补语跟在宾语和表语的后面构成宾补和表补。把有宾补的句子变成被动语态,则宾补就变成了主补。

We are made happy to love others…we are made lonely to love ourselves.(主补)
爱他人使我们幸福,在自己使我们孤单。
2.定语,同位(语)专把名词踹:
定语,同位语修饰名词性形式

3.谓语动词由状语修饰

你想摘下天上的星星,可能一个也摘不下;但也不会一无所获。
1、主语:
(1)由名词、代词(人称代词用主格)、动词不定式、动名词等充当,说明动作是“谁”发出的。如:The painter painted a very nice picture. (画家画了一幅漂亮的画。) / They fought against SARS bravely. (他们勇敢地与非典搏斗。) / To see is to believe. (耳听为虚眼见为实). / Helping animals is to help people. (帮助动物就是帮助人类。)
(2)动词不定式或动名词做主语时可用it代替,而不定式或动名词移至表语或宾语之后。如:It is very comfortable to have a Class A seat during the long journey. (在长途旅行中能有个甲等座位简直太舒服了。) / Eating too much is bad for your health.(=It is bad for your health eating too much.) (吃得太多对你的身体不利。)
(3)口语中常见主语或“主--系”省略:(It is) nothing. ((那)没有什么。)/ (It) doesn’t matter. ((那)没有关系。) / (I) thank you. ((我)谢谢你。)
(4)反意问句的附加问句,主语必须是代词:The man looks worried,doesn’t he? (这个人看上去很着急不是吗?) / Tigers are dangerous animals, aren’t they? (老虎是危险的动物不是吗?)
(5)祈使句一般省略主语。加主语时往往用来指定某个人。Keep the keyboards clean, children. (孩子们请保持键盘的清洁。) (省略了主语) / You go there and fetch me a glass of water. (你去给我弄一杯水来。)
(6)主语一般在句首,但在问句中会处于第二位和句尾;倒装句及there be句型主语在动词之后。如:Computers are made in this factory. (计算机生产于这家工厂。) / Where are they? (他们在哪儿?) / Does the boy like staying home? (这个男孩喜欢呆在家里吗?)
(7)主语与谓语必须保持单、复数的一致, 而谓语与表语或宾语之间没有这一要求。Neither Jim nor Rose has passed the exam. (Jim和Rose都没有通过考试。) / The Chinese people are a hardworking and brave people. (中华民族是一个勤劳勇敢的民族。)
(8)主语可以由从句充当,详见“主语从句”。
2、谓语:
(1)由“不及物动词”、“及物动词 宾语”或“系动词 表语”等构成,说明主语所表示的人物“干什么”或“怎么样”。如:
He travelled in space for the first time.(他首次在太空旅行。) / Who teaches you English this year?(今年谁教你们的英语?) / The pizza has gone bad. (那块烤馅饼已经变坏。) /
(2)谓语动词必须反映出人称、单复数、时态等信息,谓语动词往往由下列词语依序排列构成:[情态动词] [时态助动词] [语态助动词] [主要动词](不一定全部出现)。(见动词的时态和语态构成表) 记住:谓语部分第一个动词往往是变形动词。如:
I am sorry I am making so much noise but I have to. (对不起我发出了太大的声音但是只能这样。) / He can’t have finished reading the 800-page-long novel. (他不可能读完了那本长达800页的小说。) / Something must be done to stop the fowl flu from spreading out. (该采取措施防止
禽流感蔓延。)
(3)谓语动词切忌用“行为动词1 原形动词”、“be 原形动词”。
记住使用下列正确形式:
①情态动词 原形动词。如:You’d better go over the lesson.(你最好复习这一课。)
②shall/ will/ would 原形动词。如:They should have been there once.(他们应该去过那儿。)
③be 现在分词或者过去分词。如:What are you doing this evening?(今晚你打算做什么?)/ Many trees have been cut down since 1970s.(自从20世纪70年代大批树木被砍伐。)
④have 过去分词。如:Many trees have been cut down since 1970s.(意思同上)
⑤一般时问句和否定句中:do/does/did 原形动词。如:He does not enjoy himself very much.(他日子过的不好。)/ Did any of you see dinosaur eggs?(你们当中有谁见过恐龙蛋吗?)
⑥行为动词1 行为动词2 (不定式、动名词、现在分词、过去分词等形式)。如:He made up his mind to be a vet.(他拿定主意要做个兽医。)/ Feeling good about yourself is essential to feeling good about life.(自尊自爱是享受生活的根本。)/ They wake up the other family members, calling,“Merry Christmas!”(他们叫醒家庭的其他成员,呼喊着:圣诞快乐!)/ The kings of ancient Egypt had strong tombs built for themselves.(古代的埃及国王让人给他们自己修建坚固的坟墓。)
(4)不可用形容词、名词、代词、副词、介词短语等独立作谓语,必须在此之前加连系动词。
(5)谓语动词单复数形式:单数形式的动词有:is,was,has,does以及“动词 s”;复数形式的动词有:are,were,have以及动词原形。其他动词不分单、复数。
