1英語句子成分和結(jié)構(gòu)

1、句子結(jié)構(gòu)及成分句子成分英語的句子成分主要有六種：即主語、謂語、賓語、定語、狀語和補(bǔ)語。（可以熟記為：主謂賓，定狀補(bǔ)）除了這六種主要成分之外，還有“表語”和“同位語”的說法。但表語和系動(dòng)詞一起作謂語，因此劃分成分時(shí)，劃分在謂語上。同位語分為主語同位語和賓語同位語，屬于主語或賓語的一部分。主語主語是一個(gè)句子所敘述的主體，一般位于句首，通常由名詞性的詞來充當(dāng)?？梢宰髦髡Z的詞性或語法結(jié)構(gòu)：1.名詞 2.代詞 3.數(shù)詞 4.名詞化的形容詞（如the rich）5.不定式 6.動(dòng)名詞 7.主語從句等表示。在下面句子的主語下面畫橫線，并說出由什么充當(dāng)。During the 1990s, American c

Give up English is not an option.謂語謂語由動(dòng)詞充當(dāng)，說明主語所做的動(dòng)作或具有的特征和狀態(tài)。謂語的構(gòu)成如下：簡單謂語：由一個(gè)動(dòng)詞或動(dòng)詞短語構(gòu)成。如：He practices running every morning. He reads newspapers every day.復(fù)合謂語： 由情態(tài)動(dòng)詞或其他助動(dòng)詞加動(dòng)詞構(gòu)成。如：You may keep the book for two weeks. He has caught a bad cold. My sister is cryin

5、g over there. I have been waiting for you all the time.I would stay at home all day.由系動(dòng)詞加表語構(gòu)成。系動(dòng)詞不能單獨(dú)作謂語，要和表語一起作謂語。如：We are students. Your idea sounds great.表語表語多是形容詞，用以說明主語的身份、特征和狀態(tài)，它一般位于系動(dòng)詞（如be, become, get, look, grow, turn, seem等）之后。表語一般由名詞、代詞、形容詞、分詞、數(shù)詞、不定式、動(dòng)名詞、介詞短語、副詞及表語從句表示。畫出下列句中的表語，并說明由什么充當(dāng)。

7、受者，一般位于及物動(dòng)詞和介詞后面。賓語分為動(dòng)詞賓語和介詞賓語，分別構(gòu)成動(dòng)賓結(jié)構(gòu)和介詞結(jié)構(gòu)。畫出下列句中的賓語, 并說明由什么充當(dāng)。They planted many trees yesterday. (How many dictionaries do you have?)

8、補(bǔ)足語英語中有些及物動(dòng)詞，除有一個(gè)直接賓語以外，還要有一個(gè)賓語補(bǔ)語，才能使句子的意義完整。賓語補(bǔ)足語和賓語構(gòu)成邏輯上的主謂關(guān)系。換句話說，在意思上，賓語相當(dāng)于賓補(bǔ)的主語。帶有賓語補(bǔ)足語的一般句型為：某些及物動(dòng)詞（如make等）+賓語+賓補(bǔ)。賓補(bǔ)可由名詞、形容詞、副詞、不定式、分詞、介詞短語和從句充當(dāng)。用下畫線畫出下列句中的賓語補(bǔ)足語，并指出是什么詞充當(dāng)，同時(shí)體會(huì)賓補(bǔ)和賓語之間的邏輯關(guān)系。His father named him Dongming.

9、to lend his money to you. We saw her entering the room.We found everything in the lab in good order.We will soon make our city what your city is now.I want your homework done on time.主補(bǔ)對(duì)主語的補(bǔ)充。含有賓語補(bǔ)足語的句子在變成被動(dòng)語態(tài)，賓語作主語時(shí)，原來的賓補(bǔ)就成了主語補(bǔ)足語。He was elected monitor.She was found singing in the next room.He was

10、advised to teach the lazy boy a lesson.定語定語是對(duì)名詞或代詞起修飾、限定作用的詞、短語或句子，漢語中常用“的”表示。定語通常位于被修飾的成分前。在英語中，許多情況下，定語是放在所修飾詞后面的，這點(diǎn)與漢語習(xí)慣不同，也是許多同學(xué)不能讀懂長句的主要原因。副詞用作定語一般要后置。 People there are very friendly. (那兒的人們)He didnt like the man downstairs. （樓下的那個(gè)人）形容詞短語作定語一般放在所修飾詞之后。單個(gè)形容詞作定語一般放在所修飾詞之前，而形容詞短語作定語一般放在所修飾詞之后。The

11、next man is a scientist.The man next to me is a scientist.（我旁邊的那個(gè)人）介詞短語作定語時(shí)要后置。The boy under the tree is Tom.（樹下的那個(gè)男孩）The tallest boy in our class is John.（我們班最高的那個(gè)男孩）現(xiàn)在分詞短語、過去分詞短語、動(dòng)詞不定式作定語常后置。I have something to say.

12、st year is impressive.（去年建的那座房子） 口頭翻譯下列句子，用下畫線標(biāo)出定語部分，留意定語的位置，并說明定語是由什么詞性或結(jié)構(gòu)充當(dāng)。The letter on the desk is for Mr. Wu.The woman with a baby in her arms is his mother.We need a place twice larger than this one.She carried a basket full of eggs.Its a book worth no more than one dollar.Its a city far from

14、 back home.There are many clothes to be washed. Most of the singers invited to the party were from America.Then the great day came when he was to march past the palace in the team.狀語修飾動(dòng)詞、形容詞、副詞或整個(gè)句子, 說明動(dòng)作或狀態(tài)特征的句子成分，叫作狀語。He writes carefully. He walks slowly.(認(rèn)真地寫，慢慢地走，修飾動(dòng)詞用副詞，作狀語)This material is env

15、ironmentally friendly.（修飾形容詞用副詞，作狀語）He runs very slowly.（修飾副詞slowly, 因此very是副詞，作狀語）Unfortunately, he lost all of his money. （修飾整個(gè)句子用副詞，作狀語）幾個(gè)并列狀語的先后順序：方式地點(diǎn)時(shí)間一個(gè)句中有幾個(gè)并列狀語時(shí)，其順序較靈活，但一般是：方式地點(diǎn)時(shí)間。如：He worked hard at his lessons last year.I found a lost pen outside our school yesterday morning.He was walkin

16、g slowly outside the park at that moment.頻度副詞often, always, usually, sometimes, never等在句中的位置位于情態(tài)動(dòng)詞、系動(dòng)詞、助動(dòng)詞之后, 實(shí)義動(dòng)詞之前。You can never tell what he will do.He is often late.He is always helping others.He often came late.狀語按意義分類在句子成分中，主語、謂語、賓語、定語、表語、補(bǔ)語都比較好辨認(rèn)，如果這幾個(gè)成分都不是，那很可能就是狀語了。因此，狀語的種類很多，可以表示時(shí)間、地點(diǎn)、原因、目

17、的、結(jié)果、程度、條件、方式和讓步等。指出下列畫線部分屬于什么狀語。How about meeting again at six? Mr. Smith lives on the third floor. Last night she didnt go to the dance party because of the rain.

19、nt rain. 14. On Sundays, there is no student in the classroom. 15. Having to finish his homework, the boy needs a pen. 同位語同位語是在名詞或代詞之后并列名詞或代詞對(duì)前者加以說明的成分，近乎于后置定語。如：We students should study hard. / (students是we的同位語，都是指同一批“學(xué)生”）Its good to us students. 選擇正確答案，并口頭說出句中那個(gè)是同位語。The young man, _,works in the o

20、ffice.A. me brother B. my brother C. my brothers D. me Our English teacher, _, often helps us with study.A. Mrs. WangB. Mrs. Wangs C.

21、結(jié)構(gòu)的基礎(chǔ)。英語五種基本句型結(jié)構(gòu)如下：主語 謂語用符號(hào)表示為： （主謂） （主謂賓） （主謂間賓直賓） （主謂賓賓補(bǔ)） （主系表）主語（subject）謂語（predicate） 賓語（object） 定語（attribute）狀語 (adverbial)補(bǔ)語（complement） 表語（predicative）基本句型一： （主謂）這類句子的謂語動(dòng)詞都是不及物動(dòng)詞，都不帶賓語，但可以帶狀語。如: It is raining now. ( ) Weve worked for 5 hours. ( )The meeting lasted half an hour. ( ) Time flies

22、. ( )分析下列句子成分，并在后面括號(hào)內(nèi)標(biāo)明屬于五種基本句型中的哪一種。Dark clouds hung overhead. ( ) Gradually a smile appeared on her face. ( )He is smiling all over his face. ( ) I did well in English. ( )He talked loudly in the classroom yesterday. ( )基本句型二： （主系表）系動(dòng)詞主要是be，但還有一些動(dòng)詞有些時(shí)候也可作系動(dòng)詞，有人稱之為半系動(dòng)詞。如何辨別系動(dòng)詞有些動(dòng)詞既可作連系動(dòng)詞，又可以作實(shí)義動(dòng)詞。如

23、何來辨別呢？有一個(gè)最簡便的方法，即用連系動(dòng)詞be替換句子中的這些動(dòng)詞，句子仍然成立就是連系動(dòng)詞；反之，不能替換的，就是行為動(dòng)詞。如：She looks beautiful. (looks變?yōu)閕s之后，她是美麗的，句意沒有大的變化，looks是系動(dòng)詞。) Look at the picture.(look不能換為be, look為實(shí)義動(dòng)詞。)He felt the book with his right hand.(feel是“摸”的意思，不能換為was, 是實(shí)義動(dòng)詞。) The silk feels soft.(這種絲綢摸起來很柔軟，feels換為is之后，句意變化不大，因此是系動(dòng)詞。)辨別下

24、列斜體動(dòng)詞是系動(dòng)詞還是實(shí)義動(dòng)詞。The door stays open at night. He tasted the food, and the food tasted delicious.The book still lies open on the desk. What he said proved true. He cant proved his theory(理論).常見的系動(dòng)詞狀態(tài)系動(dòng)詞 用來表示主語狀態(tài)，只有be一詞。如： He is a teacher. 他是一名教師。持續(xù)系動(dòng)詞 用來表示主語繼續(xù)或保持一種狀況或態(tài)度，主要有keep, remain, stay, lie, st

25、and。如：He kept silent at the meeting. 他開會(huì)時(shí)保持沉默。 This matter remains a mystery. 此事仍是一個(gè)謎。The food stays fresh in the fridge. 食物在冰箱里仍然很新鮮。The house stood empty for years.房子空了數(shù)年。 He lies awake in bed.他躺在床上，醒著。表“像”系動(dòng)詞 用來表示“看起來像”這一概念，主要有seem, appear, look。如：Something seems wrong. 好像出差錯(cuò)了。He appears young. 他

26、看起來很年輕。 感官系動(dòng)詞 感官系動(dòng)詞主要有l(wèi)ook“看起來”，feel“摸起來”, smell“聞起來”, sound“聽起來”, taste“嘗起來”。This kind of cloth feels very soft. 這種布手感很軟。 This flower smells very sweet. 這朵花聞起來很香。 變化系動(dòng)詞 這些系動(dòng)詞表示主語變成什么樣。變化系動(dòng)詞主要有become, grow, turn, fall, get, go, come, run。He became mad after that. 自那之后，他瘋了。 She grew rich within a sho

27、rt time. 她沒多長時(shí)間就富了。He fell ill yesterday.他昨天病了。 Eggs go bad easily in summer. 蛋夏天容易變壞。His face went red.他的臉變紅了。 What he had dreamt of came true. 他的夢(mèng)想實(shí)現(xiàn)了。Still waters run deep.靜水流深。終止系動(dòng)詞 表示主語已終止動(dòng)作，主要有prove, turn out, 表達(dá)“證實(shí)”，“變成”之意。如：The rumor proved false. 這謠言證實(shí)有假。 His plan turned out a success. （tur

28、n out表終止性結(jié)果）What he predicted turned out (to be) wrong. 他預(yù)言的結(jié)果是錯(cuò)的。用下畫線畫出下列句中的系動(dòng)詞。His advice proved right. The shop stays open till 8 oclock. The machine went wrong. All these efforts seem in vain. These words sound reasonable. The room soon became crowded. The days are getting longer and longer. He

29、fell ill yesterday. Trees turn green in spring. What you said sounds great.系動(dòng)詞不能單獨(dú)作謂語，要和表語一起作謂語He is a student. ( )Your idea sounds great. ( )在一個(gè)英語單句中，一般情況要有謂語動(dòng)詞要注意：介詞短語和形容詞不能單獨(dú)作謂語，要和系動(dòng)詞一起作謂語。改錯(cuò)：Our school very beautiful and we like it very much. Your book on the desk.基本句型三： （主謂賓）此結(jié)構(gòu)是由“主語+及物動(dòng)詞（詞組）+賓

30、語”構(gòu)成。如：She likes English. We planted a lot of trees on the farm yesterday.用下畫線畫出下列句中的賓語。People all over the world speak English. Jim cannot dress himself. All of us believe that Jack is an honest boy. He did not know what to say. He just wanted to stay at home. He practices speaking English every da

31、y.基本句型四： （主謂間賓 直賓）有些及物動(dòng)詞可以有兩個(gè)賓語，如：give“給”，pass“遞”，bring“帶”，show“顯示”。這兩個(gè)賓語通常一個(gè)指人，為間接賓語；一個(gè)指物，為直接賓語。間接賓語一般位于直接賓語之前。一般的順序?yàn)椋簞?dòng)詞 + 間接賓語 + 直接賓語。如：He gave me a cup of tea. ( )強(qiáng)調(diào)間接賓語順序?yàn)椋簞?dòng)詞 + 直接賓語 + 介詞 + 間接賓語。如：Show this house to Mr. Smith.若直接賓語為人稱代詞：動(dòng)詞 + 代詞直接賓語 + 介詞 + 間接賓語。如：Bring it to me, please. (不能說 Bring

32、 me it, please.)常跟雙賓語的及物動(dòng)詞有：（需借助to的）allow, bring, deny, give, grant, hand, leave, lend, offer, owe, pass, pay, permit, promise, read, refuse, sell, send, show, teach, tell, wish, write等。（需借助for 的） buy, choose, fetch, get, make, order, paint, play(演奏), save, sing, spare等。一般用to多些，用for的記住常用的三個(gè)就行：get, b

33、uy, make。He sent me an English-Chinese Dictionary. = He sent an English-Chinese Dictionary to me.She bought John a book. = She bought a book for John.分析下列句子成分，口頭說出間接賓語和直接賓語。She ordered herself a new dress. She cooked her husband a delicious meal. He brought you a dictionary. He denies her nothing. I

34、 showed him my pictures. I gave my car a wash.I told him that the bus was late. He showed me how to run the machine.基本句型五： （主謂賓賓補(bǔ)）此句型的句子特點(diǎn)是：動(dòng)詞雖然是及物動(dòng)詞，但是只跟一個(gè)賓語還不能表達(dá)完整的意思，必須加上一個(gè)補(bǔ)充成分來補(bǔ)足賓語，才能使意思完整。賓語補(bǔ)足語：位于賓語之后對(duì)賓語做出說明的成分。賓語與其補(bǔ)足語有邏輯上的主謂關(guān)系，它們一起構(gòu)成復(fù)合賓語。The war made him a soldier.（“他成為一個(gè)士兵”，構(gòu)成邏輯上的主謂關(guān)系）New met

35、hods make the job easy. （）I often find him at work. （）The teacher asked the students to close the windows. （） I saw a cat running across the road.分析下列句子并劃分成分，在后面的括號(hào)內(nèi)標(biāo)明是什么充當(dāng)句子的賓語補(bǔ)足語。1. They appointed him manager. （ ） 2. They painted the door green. （ ）3. He pushed the door open. （ ） 4. They found the

36、 house deserted. （ ）5. What makes him think so? （ ） 6. We saw him out. （ ）7. He asked me to come back soon. （ ） 8. I saw them getting on the bus. （ ）9. We all think it a pity that she didnt come here. （ ）10. Ill have my bike repaired. （ ） 11. We elected him monitor. （ ）12. Dont keep the lights burni

37、ng. （ ）there be 句型此句型是由“there + be + 主語 + 狀語”構(gòu)成，用以表達(dá)“存在有”。它其實(shí)是倒裝的一種情況，主語位于謂語動(dòng)詞 be 之后，there 僅為引導(dǎo)詞（也有看作形式主語的），并無實(shí)際意義。be 與其后的主語在人稱和數(shù)上一致，有時(shí)態(tài)和數(shù)的變化?，F(xiàn)在時(shí)   there is / are     過去時(shí)   there was / were將來時(shí)   there will be/there is / are going to be. 完成時(shí)  there ha

38、s / have been可能有  there might be.   肯定有  there must be / there must have been.過去曾經(jīng)有  there used to be   似乎有  there seem / seems / seemed to be 碰巧有  there happen / happens / happened to be 可用 live, stand, come, go, lie, remain, exist, arrive等詞代替be動(dòng)詞。此時(shí)還表示存在有，但表

39、意要更具體一些。如：There lived an old man at the foot of the mountain. There came a shout for “help”.There exists no air on the moon. There lies a book on the desk. There stands a tree on the hill._ a certain doubt among the students as to the necessity of the work. A. It existed B. There existed C. They had

40、D. There had_ a beautiful palace _ the foot of the hill. A. There stand; atB. There stands; under C. Stands there; under D. There stands; atthere be 與have 的區(qū)別there be “某地有某物，某時(shí)有某事”；have 表示“某人擁有某物”。改錯(cuò)： There has a book on the desk. There will have a meeting this evening.提示：沒有there have這種表示“有”的方法。簡單句、

41、并列句和復(fù)合句句子按結(jié)構(gòu)可分為簡單句、并列句和復(fù)合句。簡單句只有一個(gè)主語(或并列主語)和一個(gè)謂語(或并列謂語)。如：He often reads English in the morning. Tom and Mike are American boys.She likes drawing and often draws pictures for the wall newspapers.（畫線部分為并列謂語，只有一個(gè)主語，仍為簡單句。）并列句由并列連詞（and, but, or等）或分號(hào)（;）把兩個(gè)或兩個(gè)以上的簡單句連在一起構(gòu)成。要注意, 逗號(hào)是不可以連接句子的，這一點(diǎn)和漢語不同。如：You

42、help him and he helps you. The future is bright; the road is tortuous. 前途是光明的，道路是曲折的。表示連接兩個(gè)同等概念，常用and, not onlybut also, neithernor, then等連接。 The teachers name is Smith, and the students name is John.He not only stole my money, but he also took my watch away.表示選擇，常用的連詞有or, eitheror, otherwise等。Hurry

43、 up, or youll miss the train.表示轉(zhuǎn)折，常用的連詞有but, still, however, yet, while, when等。He was a little man with thick glasses, but he had a strange way of making his classes lively and interesting.表示因果關(guān)系，常用的連詞有so, for, therefore等。August is the time of the year for rice harvest, so every day I work from dawn

44、 until dark.復(fù)合句復(fù)合句含有兩個(gè)或兩個(gè)以上主謂結(jié)構(gòu)，其中一個(gè)主謂結(jié)構(gòu)作另一個(gè)的成分。（而并列句的兩個(gè)主謂結(jié)構(gòu)間是并列關(guān)系， 而不是從屬關(guān)系。）當(dāng)簡單句的一個(gè)成分從詞或詞組變?yōu)榫渥訒r(shí)，整個(gè)句子就成為復(fù)合句了。It is wrong. （只有一個(gè)主謂結(jié)構(gòu)，是簡單句。）What he said is wrong. （what he said,是一個(gè)主謂結(jié)構(gòu)，he為主語，said為謂語，what是賓語。What he said is wrong. 是另外一個(gè)主謂結(jié)構(gòu)，What he said作主語，是主語從句；is wrong系表結(jié)構(gòu)作謂語。因此，本句是復(fù)合句。）The boy over

45、there is my brother. （只有一個(gè)主謂結(jié)構(gòu)，是簡單句。）The boy who is wearing a hat is my brother. （The boy over there is my brother.只有一個(gè)主謂結(jié)構(gòu)，是簡單句。當(dāng)over there變?yōu)?who is wearing a hat時(shí)（也是一個(gè)主謂結(jié)構(gòu)），整個(gè)句子就變成了復(fù)合句，who is wearing a hat是定語從句。）I was doing my homework at six. （只有一個(gè)主謂結(jié)構(gòu)，是簡單句。）I was doing my homework when he came i

46、n. （I was doing my homework是一個(gè)主謂結(jié)構(gòu)，he came in也是一個(gè)主謂結(jié)構(gòu)。后面一個(gè)主謂結(jié)構(gòu)作前一個(gè)的時(shí)間狀語，是時(shí)間狀語從句。因此本句是復(fù)合句。）從上面這幾個(gè)句子，我們可以看出：一個(gè)句子如果含有從句，如名詞性從句（主語從句、賓語從句、表語從句和同位語從句）、定語從句和狀語從句等，這個(gè)句子就是復(fù)合句。復(fù)合句的從句和主句之間要用連接詞連接。在上面句1中，what是連接詞；在句2中，關(guān)系代詞who就是連接詞；在句3中，when起連接作用。判斷下列句子是簡單句、并列句還是復(fù)合句。We often study Chinese history on Friday afte

47、rnoon. The boy who offered me his seat is called Tom.There is a chair in this room, isnt there?My brother and I go to school at half past seven in the morning and come back home at seven in the evening.He is in Class One and I am in Class Two. He was fond of drawing when he was yet a child.Neither h

48、as he changed his mind, nor will he do so. What he said at the meeting is very important, isnt it?The farmer is showing the boy how to plant a tree. Both Tom and Jack enjoy country music.Right now it is the summer vacation and Im helping my Dad on the farm.It is the time of year for the rice harvest

49、, so every day I work from dawn until dark.Sometimes we go on working after dark by the lights of our tractors.We grow rice in the south of the States, but in the north where it is colder they grow wheat.Although the farm is large, my Dad has only two men working for him.引導(dǎo)的是什么從句，不僅要根據(jù)連詞，還要根據(jù)句子結(jié)構(gòu)和句意

50、來判別說出下列復(fù)合句中，where引導(dǎo)的是什么從句。You can find it where you left it.（ ） Tell me the address where he lives.（ ）I dont know where he comes from.（ ） Where he was born is not known yet.（ ）This place is where they once lived.（ ）一個(gè)句子有兩個(gè)主謂結(jié)構(gòu)時(shí)，要考慮它們之間的連接問題一個(gè)句子如果出現(xiàn)兩個(gè)主謂結(jié)構(gòu)，那它就不是簡單句了，要么是并列句，要么是復(fù)合句。這時(shí)我們就要考慮連接詞的問題。直接用逗號(hào)連接的兩個(gè)簡單句是錯(cuò)誤的。這時(shí)，我們有四種方法來改正這個(gè)錯(cuò)句：改為并列句：我們可以使用and, so, but等并列連詞來把它們連接起來。改為復(fù)合句：加上從屬連詞，把其中的一個(gè)分句改為狀語從句、定語從句或名詞性從句。改為簡單句：把其中的一個(gè)主謂結(jié)構(gòu)的
