句子成分(一)句子成分的定义:构成句子的各个部分叫做句子成分。句子成分有主要成分和次要成分;主要成分有主语和谓语;次要成分有表语、宾语、定语、状语、补足语和同位语。(二)主语:主语是一个句子所叙述的主体,一般位于句首。但在therebe结构、疑问句(当主语不是疑问词时)和倒装句中,主语位于谓语、助动词或情态动词后面。主语可由名词、代词、数词、不定式、动名词、名词化的形容词和主语从句等表示。例如:Duringthe1990s,Americancountrymusichasbecomemoreandmorepopular.(名词)WeoftenspeakEnglishinclass.(代词)One-thirdofthestudentsinthisclassaregirls.(数词)Toswimintheriverisagreatpleasure.(不定式)Smokingdoesharmtothehealth.(动名词)Therichshouldhelpthepoor.(名词化的形容词)WhenwearegoingtohaveanEnglishtesthasnotbeendecided.(主语从句)Itisnecessarytomasteraforeignlanguage.(it作形式主语,真正的主语为后面的不定式)(三)谓语:谓语说明主语所做的动作或具有的特征和状态。动词在句中作谓语,一般放在主语之后。谓语的构成如下:1、简单谓语:由一个动词或动词短语构成。如:Hepracticesrunningeverymorning.2、复合谓语:(1)由情态动词或其他助动词加动词原形构成。如:Youmaykeepthebookfortwoweeks.Hehascaughtabadcold.(2)由系动词加表语构成。如:Wearestudents.(四)表语:表语用以说明主语的身份、特征和状态,它一般位于系动词(如be,become,get,look,grow,turn,seem等)之后。表语一般由名词、代词、形容词、分词、数词、不定式、动名词、介词短语、副词及表语从句表示。例如:OurteacherofEnglishisanAmerican.(名词)Isityours?(代词)Theweatherhasturnedcold.(形容词)Thespeechisexciting.(分词)-ing形式作adj.,故为现在分词,而非动名词Threetimessevenistwentyone?(数词)HisjobistoteachEnglish.(不定式)Hishobby(爱好)isplayingfootball.(动名词)-ing形式作n.,故为动名词,而非现在分词Themachinemustbeoutoforder.(介词短语)Timeisup.Theclassisover.(副词)Thetruthisthathehasneverbeenabroad.(表语从句)(五)宾语:宾语表示动作的对象或承受者,一般位于及物动词和介词后面。例如:Theywenttoseeanexhibition(展览)yesterday.(名词)Theheavyrainpreventedmefromcomingtoschoolontime.(代词)Howmanydictionariesdoyouhave?Ihavefive.(数词)Theyhelpedtheoldwiththeirhouseworkyesterday.(名词化形容词)Hepretendednottoseeme.(不定式短语)Ienjoylisteningtopopularmusic.(动名词短语)-ing形式作n.,故为动名词,而非现在分词Ithink(that)heisfitforhisoffice.(宾语从句)宾语种类:(1)双宾语(间接宾语+直接宾语),例如:Lendmeyourdictionary,please.双宾语(直接宾语+to+间接宾语),例如:Lendyourdictionarytome,please.(2)复合宾语(宾语+宾补),例如:Theyelectedhimtheirmonitor.(六)宾语补足语:英语中有些及物动词,除有一个直接宾语以外,还要有一个宾语补足语,才能使句子的意义完整。带有宾语补足语的一般句型为:某些及物动词(如make/have等+宾语+宾补)。宾补可由名词、形容词、副词、不定式、分词、介词短语和从句充当。例如:Hewassotiredthathefellasleepimmediately.(结果状语)Sheworksveryhardthoughsheisold.(让步状语)Iamtallerthanheis.(比较状语)句子种类(一)句子种类两种分类法1、按句子的用途可分四种:1)陈述句(肯定、否定):Heissixyearsold./Shedidn’thearofyoubefore.2)疑问句(一般、特殊、选择、反意):Dotheylikeskating?/Howoldishe?/Ishesixorsevenyearsold?/Marycanswim,can´tshe?3)祈使句:Becareful,boys./Don´ttalkinclass.4)感叹句:Howclevertheboyis!2、按句子的结构可分三种:1)简单句:只有一个主语(或并列主语)和一个谓语(或并列谓语)。e.g.HeoftenreadsEnglishinthemorning.TomandMikeareAmericanboys.Shelikesdrawingandoftendrawspicturesforthewallnewspapers.2)并列句:由并列连词(and,but,or等)或分号(;)把两个或两个以上的简单句连在一起构成。e.g.Youhelphimandhehelpsyou.Thefutureisbright;theroadistortuous.前途是光明的,道路是曲折的。3)复合句:含有一个或一个以上从句的句子。复合句包含:名词性从句(主语从句、宾语从句、表语从句和同位语从句)、定语从句和状语从句等。e.g.TheforeignvisitorstookalotofpictureswhentheywereattheGreatWall.(二)简单句的五种基本句型1、主语+系动词+表语:e.g.Heisastudent.2、主语+不及物动词:e.g.Wework.3、主语+及物动词+宾语:e.g.Henryboughtadictionary.4、主语+及物动词+双宾语(间接宾语+直接宾语):e.g.Myfatherboughtmeacar.5、主语+及物动词+复合宾语(宾语+宾补):e.g.Tommadethebabylaugh.注:其他各种句子都可由这一种基本句型扩展、变化或省略而构成。主语---动词----表语:在这一句型中,动词是系动词,划线部分为表语。1.Mr.Brownisanengineer.(名词作表语)2.Gradualyhebecamesilent.(形容词作表语)3.Sheremainedstandingforahour.(现在分词作表语)4.Thequestionremainedunsolved.(过去分词作表语)5.Themachineisoutoforder.(介词短语作表语)6.Thetelevisionwason.(副词作表语)7.Hisplanistokeeptheaffairsecret.(动词不定式作表语)8.Myjobisrepairingcars.(动名词作表语)9.Thequestioniswhatyouwanttodo.(从句作表语,即:表语从句)【注意】在下面的句子中,形容词作表语,在表语的后面常常接不定式结构。I’mhappytomeetyou./Theyarewillingtohelp./Wearedeterminedtofollowhisexample.主语——动词:在这一句型中,动词为不及物动词及不及物的动词词组。在有的句子中,不及物动词可以有状语修饰。1.Thesunisrising.2.I’lltry.3.Didyousleepwell?(well做状语,修饰不及物动词sleep)4.Theenginebrokedown.【注意】在此句型中,有少数不及物动词表达被动含义,表达主语本身所具有的特性,不用被动语态。1.Thebooksellswell./2.Thewindowwon´tshut.3.Thepenwritessmoothly./4.Cheesecutseasily.主语———动词———宾语:在此句型中,动词为及物动词,划线部分为宾语。1.Doyouknowthesepeople(them)?(名词或代词作宾语)2.Ican´texpressmyselfinEnglish.(反身代词作宾语)3.Hesmiledastrangesmile.(同源宾语)4.Wecan´taffordtopaysuchaprice.(不定式作宾语)5.Wouldyoumindwaitingafewminutes?(动名词作宾语)6.IhopethatIhavesaidnothingtopainyou.(从句作宾语,即:宾语从句)【注意】并不是所有的及物动词都可以接上述各种情况作宾语,不同的动词有不同的用法,所以,在学习动词时,一定要掌握其用法。主语———动词———宾语———宾语:在此句型中,动词可以称作双宾语动词,在英语中,这样的动词并不多,在学习中遇到时,要牢记。后面的宾语为间接宾语和直接宾语,其中,间接宾语在前,一般表人,直接宾语在后,一般表物。这类句型有三种情况。第一种情况,间接宾语可以改为由to引导的短语。1.Hehandedmealetter.Hehandedalettertome.2.Shegavemehertelephonenumber.Shegavehertelephonenumbertome.第二种情况,间接宾语可以改为由for引导的短语。3.Shesangusafolksong.Shesangafolkforus.4.Shecookedusadeliciousmeal.Shecookedadeliciousmealforus.第三种情况,直接宾语可以由宾语从句充当。5.TellhimI´mout.6.CanyouinformmewhereMissGreenlives?主语——动词——宾语——宾语补足语:在此句型中的动词,叫做可以跟复合宾语的动词,在英语中,这样的动词也不多。后面的宾语补足语是说明宾语的情况的,宾语和宾语补足语一起被称作复合宾语。这个句式是英语中比较复杂的一个句式,因为复合宾语的构成内容较多。下面句子中划线部分为宾语补足语。1.Hefoundhisnewjobboring.(形容词作宾补)2.ThecalledtheirdaughterMary.(名词作宾补)3.Thisplacedherinaverydifficultposition.(介词短语作宾补)4.Wewenttoherehousebutfoundherout.(副词作宾补)5.Whatdoyouadvisemetodo?(不定式作宾补)6.Wethoughthimtobeanhonestman.(tobe作宾补)7.Hebelievedthemtohavediscussedtheproblem.(不定式的完成式作宾补)8.Hebelievedhertobetellingthetruth.(不定式的进行式作宾补)9.Didyounoticehimcomein?(不带to的不定式作宾补)10.IsawherchattingwithNancy.(现在分词作宾补)11.Hewatchedthepianocarriedupstairs.(过去分词作宾补)【注意】在这个结构中,可以出现用it作形式上的宾语,把真正的宾语放在宾语补足语的后面。在此结构中,宾语常常是动词不定式或宾语从句。1.Hefeltithisdutytomentionthistoher.(分析:it是形式宾语,hisduty是宾语补足语,tomentionthistoher是真正的宾语。2.Ithinkitbestthatyoushouldstaywithus.(分析:it是形式宾语,best是宾语补足语,thatyoushouldstaywithus是真正的宾语。3.therebe句型是一种特殊的句子,真正的主语在后面,含义为“有…”①谓语动词和主语保持一致:Thereisatelevisioninthesittingroom.②有两个或更多的主语时,动词一般和最近的一个保持一致:Therearetwogirlsandaboydancinginthehall.③主语的后面有时有修饰语:Therearealotofdifficultiesfacingus.Thereweremanythingstobedone(此处也可以使用todo).④谓语动词be可以有时态的变化:Therewillbeaconcertintheparktonight.Therewaslittlechangeinhim.⑤谓语也可以有不定式构成的复合谓语。Thereusedtobeacinemahere.Thereseemstobesomethingthematterwithher.Istheregoingtobeanyactivitytonight?⑥therebe句式变疑问句,把be提前;变反意疑问句也要借助there。Isthereanyhopeofgettingthejob?Thereisnothingwrongwithyourwatch,isthere?⑦therebe句型中也可以使用诸如:live,follow,come,stand,sit,exist等不及物动词:Onceuponatime,therelivedafishermanontheisland.Therecameaknockatthedoor.Atthetopofthehilltherestandsanoldtemple.⑧用于非谓语的情况下,有时用不定式的复合结构theretobe或动名词的复合结构和独立主格结构therebeing:Youwouldn’twanttheretobeanotherwar.(不定式的复合结构)Theteacherwassatisfiedwiththerebeingnomistakesinhishomework.(动名词的复合结构)Therebeingnothingelsetodo,wewenthome.(独立主格结构)(三)并列句的分类并列句基本概念:并列复合句是由两个或两个以上并列而又独立的简单句构成。两个简单句常由并列连接词连在一起;但有时不用连接词,只在两个简单句之间用一逗号或分号。1、表示连接两个同等概念,常用and,notonly…butalso…,neither…nor…,then等连接。e.g.Theteacher’snameisSmith,andthestudent’snameisJohn.2、表示选择,常用的连词有or,either…or…,otherwise等。e.g.Hurryup,oryou’llmissthetrain.3、表示转折,常用的连词有but,still,however,yet,while,when等。e.g.Hewasalittlemanwiththickglasses,buthehadastrangewayofmakinghisclasseslivelyandinteresting.4、表示因果关系,常用的连词有so,for,therefore等。e.g.Augustisthetimeoftheyearforriceharvest,soeverydayIworkfromdawnuntildark.(四)主从复合句:主从复合句由一个主句和一个或一个以上的从句构成。主句为句子的主体,从句只用作句子的一个次要成分,不能独立成为一个句子。从句通常由关联词引导,并由关联词将从句和主句联系在一起。分类:从句按其在复合句中的作用,分为主语从句、表语从句、宾语从句、同位语、定语从句和状语从句等。(详见各种从句分解)(五)其他要点1、陈述句的否定(1)在含有宾语从句的主从复合句中,当主句的谓语动词是think,expect,believe,suppose,guess,fancy,imagine等,且主句主语是第一人称时,宾语从句谓语的否定习惯上要移到主句谓语上,如:Idon'tthinkheisright.(2)含有否定意义的副词never,seldom,hardly,scarcely,rarely,barely的句子应视为否定句,如:Ihaveneverbeentherebefore.2、反意疑问句(1)need和dare既可作情态动词,又可作实意动词,在反问部分须加以区别,如Weneedn'tleave,needwe?Wedon'tneedtoleave,dowe?(2)陈述部分出现否定意义的副词或代词如never,seldom,few,hardly,little等时,反问部分须用肯定形式如:Heseldomcomes,doeshe?(3)陈述部分用不定代词作主语时,反问部分的主语用it,如:Nothingcanstopme,canit?陈述部分用everybody,everyone,somebody,someone,等作主语时,反问部分常用it,有时也用they,如:Everybodyknowsthat,don'tthey?(4)陈述部分包括usedto时,反问部分可有两种形式,如:Youusedtogetupearly,usedn't(didn't)you?(5)陈述部分是"there+be"结构时,反问部分用there,如:There'ssomethingwrongwithyou,isn'tthere?(6)陈述部分是含有宾语从句的主从复合句时,反问部分的主语和谓语应和主句保持一致,如:Henevertoldotherswhathethought,didhe?但,如果是Ithink,Ibelieve等+宾语从句时,反问部分须和从句的动词保持一致,反问句中肯定或否定的选择取决于整体,如,Idon'tthinkheisright,ishe?Idon'tbelievehedoesthat,doeshe?(7)祈使句中的反义疑问句基本原则若陈述部分为祈使句,反意疑问句通常用willyou,won’tyou,wouldyou等:Mailthelettertoday,willyou?今天就把信发掉,好吗?Trytobebackbytwo,won’tyou?设法两点之前回来,好吗?Ifyouwanthelp,letmeknow,wouldyou?如果你需要帮助,告诉我,好吗?【注】若陈述部分为否定式,则反意疑问句部分只用willyou:Don’tforgettoposttheletter,willyou?请别忘了寄信。有时根据语境的需要,反意疑问句也可以用canyou,can’tyou等:Givemesomecigarettes,canyou?给我些香烟,可以吗?Walkfaster,can’tyou?走快点,不行吗?一般说来,用willyou,won’tyou,wouldyou等构成的反意疑问句语气较委婉。比较:Bequiet,willyou?请安静,好吗?Bequiet,can’tyou?你不能安静点吗?当祈使句为Let’s…时反意疑问句总是用shallwe:Let’sphonehernow,shallwe?我们现在就给她打电话,好吗?Let’sgotothecinematonight,shallwe?今晚咱们去看电影,好吗?当祈使句为Letus…时,若表示请求,反意疑问句用willyou;若表示建议,反意疑问句用shallwe:Letusknowyouraddress,willyou?请把你的地址告诉我们,好吗?Letusgoswimmingtogether,shallwe?我们一起去游泳好吗?【注】let’s…只表示建议,所以其后反意疑问句总是用shallwe。而letus…既可表示建议请求,也可表示建议(较正式),其后的反意疑问句要根据这两种不同情况分别使用willyou和shallwe。当祈使句带有主语时,有时祈使句带有自己的主语,此时不要将其误认为是陈述句:Jim,yougotheretohelphim,willyou?吉姆,你去那儿帮他,好吗?Yougirlsstandinthefrontrow,willyou?你们女孩子站在前排,好吗?【注】不要将这类祈使句误认为是陈述句,而误用don’tyou这样的反意疑问句。例题:例1,Don'tforgettoposttheletter,_______?A.willyouB.doyouC.won'tyouD.shallyou解析:该题答案为A,在否定句、祈使句后只用"willyou"?,但肯定的祈使句后可用如,Waitforme,will(won't,can,can't,could)you?例2,Let'sgooutforawalk,_______?A.willyouB.won'tyouC.shallweD.dowe解析:该题答案为C,let's…后加上shallwe来表语气婉转、客气,而在letus后加上willyou。例3,Hehardlywritestoyou,_______?A.doesn'theB.doesheC.dotheyD.hashe解析:该题答案为B,hardly否定副词,反问部分要用肯定形式。3、感叹句Whata/an/无+形容词+名词(+主语+表语)!How+形容词+a/an/the/无+名词+主语+表语!How+副词+主语+谓语!Whatabeautifulparkitis!Howbeautifulaparkitis!Howbeautifultheparkis!Howweworked!4、祈使句(一般无主语)Takecare!Don'tstandthere.Pleaseopenthedoorfortheoldlady.练习题一、指出下列句子划线部分是什么句子成分:2.Hehandedmethenewspaper.3.Ishallansweryourquestionafterclass.4.WhatabeautifulChinesepainting!6.Hisjobistotrainswimmers.7.HetookmanyphotosofthepalacesinBeijing.8.ThereisgoingtobeanAmericanfilmtonight.10.Hiswishistobecomeascientist.11.Hemanagedtofinishtheworkintime.12.Tomcametoaskmeforadvice.13.HefounditimportanttomasterEnglish.15.Tobehonest;yourpronunciationisnotsogood.17.Hesatthere,readinganewspaper.18.Itisourdutytokeepourclassroomcleanandtidy.19.Henoticedamanentertheroom.20.Theapplestastedsweet.二、判断下列句子是简单句、并列句还是复合句:1.WeoftenstudyChinesehistoryonFridayafternoon.2.TheboywhoofferedmehisseatiscalledTom.5.HeisinClassOneandIaminClassTwo.6.Hewasfondofdrawingwhenhewasyetachil
