句子成分:主语、谓语、宾语、表语、定语、宾语补足语和状语
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,主语是句子陈述的对象,说明是谁或什么,表示句子说的是“什么人”,或”什么事“,如“我写字”中的“我”,做出
写字这个动作.“写”则是谓语,“字”是宾语,是接受谓语“写”这个动作的对象,因此是宾语.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 ring 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.)(比较好看,避免头重脚轻)
(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:是对主语动作或状态的陈述或说明,指出“做什么”,“是什么”或“怎么样”,在主语后接宾语,又称受词,是一个动作的接受者.
(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](现在完成时)+[语态助动词](如被动语态)+[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?)---表示一般将来时/ 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.
谓语部分第一个动词的形式\x09单数形式\x09复数形式
一般现在时be(是)动词;
现在某些时态和语态的助动词be\x09am (单一); are (单二); is (单三); \x09are
一般过去时be(是)动词;
过去某些时态和语态的助动词be\x09was (单一); were (单二); was;(单三)\x09were
一般现在时have(有)动词;
现在完成时态的助动词have\x09have (单一); have (单二); has (单三);\x09have
一般现在时行为动词和助动词do\x09do (单一、单二); does (单三)\x09do
实意动词和连系动词的一般现在时动词(否定和疑问句除外)\x09原形动词(单一、单二); 动词+s /es (单三)\x09原形动词
其他各时态语态的谓语动词\x09单复数形式相同
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 is held every other year, isn’t it? ----Yes, it
is.(奥运会每两年举办一次,是吗?----是的.)
3、宾语:又称受词,是指一个动作(动词)的接受者.宾语分为直接宾语和间接宾语两大类,
其中直接宾语(经常指被做的人)指动作的直接对象,间接宾语说明动作的非直接,但受动作影响的对象.一般而言,及物动词后面最少要有一个宾语,而该宾语通
常为直接宾语,有些及物动词要求两个宾语,则这两个宾语通常一个为直接宾语,另一个为间接宾语.
(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 that the
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 enjoy watching 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
a children’s doctor is very rewarding.(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 he write 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 away the 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 me some 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 a kite. (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 job rather 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 doctor after
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 feel like 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,turn get,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 sorry for 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 only interested
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 in thinking 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 top drawer.(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 and father are both
college teachers.(他的父母都是大学教师.) / This is the day that I can never forget
in my life.(这是我一辈子难忘的日子.)
(2) 单词做定语时一般放在被修饰的名词前面,而且有一定的次序:
冠词/
物代\x09年龄/形状/
大小/温度\x09色彩\x09来源\x09质地/
材料\x09目的/
用途\x09被修饰的名词(中心词)

(3)
时间副词(now,then,today,yesterday,...)、地点副词(here,there,back,in,out,home,...作
定语时放在被修饰的名词后面.如:I could not find my way out, so I stayed there all
along. (我找不到出去的路,所以就一直呆在那儿.)
(4) 介词短语修饰名词时只能放在名词的后面:The monkey in the cage was caught yesterday. (笼子里的猴子是昨天逮着的.)
(5) 形容词修饰复合不定代词时,往往后置.如:He remembered everything unusual. (他记得所有不寻常的事情.)
(6) 定语还可以用从句充当,详见 定语从句.
(7) 注意:由于定语属于修饰性的成分,因此它常归入主语、宾语、表语之中,不作为句子的主要成分.
6、状语:
(1)
说明动作“何时”、“何地”、“如何”发生,或者说明形容词或副词的程度,一般由副词、介词短语、不定式、状语从句等充当.如:I was not
born yesterday.(我又不是昨天才出世的娃娃.)/ For many of these families a college
ecation was something new.(对其中的许多家庭来说,大学教育是件新事物.)/ He woke up to find
his house on fire.(他醒来发现房子着火了.) / You cannot leave until your work is
finished.(在你的工作被完成以前你不能离开)
(2)
副词作状语位置较为灵活,详见《六•2》“副词在句子中的位置以及作用”;介词短语作状语,位置基本固定,详见《七•4》“介词短语在句子中的位置”;不
定式作状语,一般表示目的、结果,详见《八•7》“动词的非谓语形式”;从句作状语,详见《主从复合句》的“状语从句”.
(3)
多个状语相连时,一般先单词、后短语,先地点、后时间,先小概念、后大概念.如:He went ouf of the room at a
quarter to 23:00 last night and then disappeared into the
dark.(他昨夜22点3刻从房间里出来,然后消失在黑暗之中.) /
(4) 状语还可以用从句来充当,有时间状语从句、地点状语从句、原因状语从句、目的状语从句、结果状语从句、比较状语从句、让步状语从句、条件状语从句等.详见“状语从句”.
(5) 注意:由于状语属于修饰性的成分,常归入谓语,因此不作为句子的主要成分.
7、宾语补足语:
(1)
补充说明宾语的动作、状态的成分为宾语补足语,常由名词、形容词、动词非谓语形式(不定式、现在分词、过去分词等)、介词短语等充当.如:Call
him Jim, please. (请叫他Jim.) / I tried my best to make him happy.
(我竭尽所能让他开心.) / Ask her to come to dinner tomorrow. (请他明天来.) / He let the
smaller animals bring food to him. (他让小动物们给他带食物来.)
(2) 部分表示位置、方向的副词也可以作宾语补足语.如:Let him in, I tell you! (我跟你说,让他进来!)/ Please put it away. (请把它收起来.)
(3) 不定式或分词作宾语补足语的情况 (略)
