我英语基础不好.您能解释下句子成分与结构么?
英语语法——英语句子成分分析
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 dancedhappily. 3)She attracts. 4)Many people living in the country. 5)All the bookson the desk over there.
以上这些形式都不能构成英语句子.

英语句子八呀八大块, 主谓宾表真呀真实在;

(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 Rosehas 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 spacefor 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 hasgone 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 ammaking 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 bedone 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 thelesson.(你最好复习这一课.)
②shall/ will/ would+原形动词.如:They should have beenthere 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 havebeen 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 seedinosaur 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 mindto be a vet.(他拿定主意要做个兽医.)/ Feeling good about yourself is essential to feeling goodabout 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 ofancient 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.

记住:主语、谓语单复数必须保持一致.(参见“4、名词或代词作主语时和谓语之间的单复数的一致问题:”) Air and water is necessary to us all.(空气和水对于我们大家是必不可少的.)
(6)一般问句和反意问句的回答不使用行为动词,应该使用“是”动词、情态动词、助动词(be,will,have,do以及变形).如:The Olympic Games isheld every other year, isn’t it? ----Yes, itis.(奥运会每两年举办一次,是吗?----是的.)
3、宾语:
(1) 由名词、代词(人称代词要用宾格)、不定式、动名词、(宾语)从句充当,表示动作的承受者是“谁”或者是“何物”.如: The angel also came to Joseph and told him the same thing.(那个天使同样来到约瑟夫面前并且告诉他同样的事情.)(代词和名词充当两个宾语) / He told me thatthe company could not afford to pay him so much money.(他告诉我说公司付不起他那么多的钱.)(不定式作宾语) / They enjoywatching football games so much that they often forget their lessons.(他们如此喜爱看足球以至于常常忘记了他们的功课.)(动名词作宾语) / I think to be achildren’s doctor is veryrewarding.(我认为当个儿童医生是很值得的.)(从句作宾语)
(2) 只有及物动词或介词才有宾语,不及物动词没有宾语,如果涉及到事物,则必须在不及物动词后面加合适的介词.Listen to the radio.(listen不是及物动词,故加to.) / Can you hear anything exciting?(你能听到什么令人兴奋的消息吗?)
(3) 宾语一般放在及物动词或介词的后面,但是在疑问句中,如果宾语是疑问词,则宾语要放在句首.介词的宾语如果是疑问词,则可以放在介词后或句首.如:What did he see? (他看见了什么?) / What does hewrite a letter with? (他用什么写的信?) / With what does he write a letter? (他用什么写的信?)
(4)“动词+副词+宾语”结构中,如果宾语是代词,则代词必须放在“动”“副”之间.如:Please put the shoes away. (请把鞋子收起来.) / Please put awaythe shoes. (请把鞋子收起来.) / Please put them away. (请把它们收起来.)
(5) 动词后面跟双宾语时可以采用两种结构:
①动词+间接宾语(人)+直接宾语(物).如:He often gives mesome help. (他常常帮我.)
②动词+直接宾语+介词+间接宾语.注意,一般情况介词用to,但动词是make, buy, borrow时,介词用for.如: Please make me akite. (请给我做个风筝.)或Please make a kite for me.
(6) 在“动词+宾语+宾补”结构中,如果宾语是不定式、动名词、宾语从句,则常用it做形式宾语,而将实际的宾语移到补语后面去.如:I found the jobrather difficult. (我发觉这个工作相当难做.) / I found it rather difficult to do the job.
(7) 宾语可以由从句充当,详见“宾语从句”.
4、表语:
(1) 说明主语的身份、性质、状况等含义的成分,通常由形容词、副词、介词短语、名词、代词等充当.如:He became a doctorafter he left high school.(高中毕业他当上了医生.) / The rubber wheels are over there.(橡胶轮子在那边.) / He does not feellike eating anything today because he has caught a bad cold.(他今天不想吃任何东西因为他得了重感冒.) / Who is it?(谁呀?)
(2) 表语只能放在连系动词(如:be,look,become,turnget,grow,feel,seem) 之后,对表语进行提问的句子除外.
(3) 代词做表语一般用主格,口语中常用宾.如:It’s I. (It’s me.)是我.
(4) 只能作表语的形容词有:sorry,afraid,alone,asleep,awake,ill,well,sure,interested等等.He was terribly sorryfor his carelessness.(他很为他的粗心而歉疚.) / Please make no noise here; the baby is asleep.(请不要发出响动,婴儿正熟睡呢.) / I am onlyinterested in sitting in a boat and doing nothing at all!(我只是对独坐孤舟无所事事感兴趣.) / I am not alone inthinking so.(并非只有我才这样想的.)
(5) 表语也可以由从句充当,详见“表语从句”.
5、定语:
(1) 修饰名词或代词的成分,常由形容词、名词(含所有格)、代词(物主、指示、疑问、不定)、介词短语、不定式(短语)充当,在初三阶段还学习了定语从句做定语的知识.如:Put it in the topdrawer.(把它放在最上层的抽屉里.) / France and Switzerland are European countries. (法国和瑞士是欧洲国家.) / His mother andfather are both college teachers.(他的父母都是大学教师.) / This is the daythat I can never forget in my life.(这是我一辈子难忘的日子.)
