一、主系表结构主谓宾=主语+实义动词+宾语,be是系动词,不能用于主谓宾中。主系表=主语+系动词(最常见的是be,还有“五感”feel、look、sound、smell、taste和其它动词如become、grow…等)+表语(名词、代词、形容词、时间地点副词、介词短语、表语从句…等)。如Iamaboy.这句话中没有宾语,属于主系表,I是主语,系动词am是谓语动词,aboy是表语,系动词和表语合起来作谓语。由此可见在主系表中,谓语≠谓语动词;而在主谓宾中,谓语=谓语动词,如Ilovemyparents.总之,系动词和宾语是不共戴天的仇人,誓不两立。系动词后面接的是表语,而宾语前面接的是谓语。所谓主系表结构就是英语句子中的主要成分是主语、系动词和表语。主要用以说明主语的特征,状态,身份等。定义主系表(S+V+P):1.主语(Subject)2.系动词(Linkverb)3.表语(Predicative)所谓主系表结构就是英语句子中的主要成分是主语、系动词和表语。主要用以说明主语的特征,状态,身份等。1.主语(Subject):主语是一句话的中心,表示所说的是谁或是什么,其位置一般放在句首。英语中主语一般不省略。主语主要由名词、动名词、代词或起名词作用的短语或从句来充当。例如:LiLeiisaChineseboy.(LiLei是名词,作主语。)HeisfromEngland.(He是代词,作主语。)Feedingthebirdsismyhobby.(“Feedingthebirds”是动名词短语,作主语。)Whatshesaidisright.(“Whatshesaid”是从句,作主语。2.系动词(Linkverb):系动词本身有一定的词义,但不能独立作谓语,必须和句子中的表语一起构成谓语。简单地说,将主语和表语联系在一起,并构成一个完整句子的动词就叫做系动词。目前学到的系动词有be,feel,look,sound,taste,smell等。例如:Thisflowerisbeautiful.Ifeltverytired.Youlookworried.Ittastesdelicious.常见的系动词•(1)表示特征和存在状态的•be,feel,look,smell,taste,sound.•(2)表示状态延续的•keep•(3)表示状态变化的•become,get,turn,go,come3.表语(Predicative):表语是用来说明主语的身份、特征或状态的。它又叫作主语补足语。表语位于系动词之后,主要由名词、代词、形容词、数词、副词、介词短语、分词(短语)或动名词(短语)等来充当。例如:Iamfine.(fine是形容词,作表语)Heisaboy.(boy是名词,作表语)Fiveplustwoisseven.(seven是数词,作表语)Wearehere.(here是副词,作表语)Heisnotathome.(“athome”是介词短语,作表语)Myhobbyisreading.(reading是动名词,作表语)二、Therebe句型therebe:表示某地有某物,指没有生命的物体有。例如:Therearemanybooksintheschoolbag.have/has:表示有生命的人或者动物有。例如:Ihavemanybooks.看名词单数is复数are不可数的用isThere_____adollinthetoybox.A.isB.areThere_____somebreadontheplate.A.isB.areThere_____alotofgreentreesinthePark.A.isB.areThereisacatandtwodogsunderthetree.Therearetwodogsandacatunderthetree.就近原则只要看到be动词后面的词是复数名词,就用are,否则就用is。当然还要注意时态哦!There_____adeskandfifty-fivechairsintheclassroom.A.areB.isThere_____fifty-fivechairsandadeskintheclassroom.A.areB.isTherebe---的一般疑问句Thereisaradioonthedesk.Istherearadioonthedesk?Yes,thereis./No,thereisn’t.Therearesomeshoesunderthebed.Arethereanyshoesunderthebed?Yes,thereare./No,therearen’t.规则:is/are要提前,some变any,其他都不变.单选•1.---Youdon'tlookvery___.Areyouill?•---No,I'mjustabittired.•A.goodB.wellC.strongD.healthy•2.Whathesaidsounds_____.•A.nicelyB.pleasantly•C.friendlyD.wonderfully•3.Theseorangestaste_____.•A.goodB.well•C.tobegoodD.tobewell1.Thecottonfells______.(A.softB.softly)2.Ifelt______sorryathiswords.(A.terribleB.terribly)3.Thelittleherolooked______attheenemy.(A.angryB.angrily)4.Tasting______,thefoodwassoonsoldout.(A.goodB.well)5.Itis______ofyoutoact______.(A.badB.badly)6.Travelingis______,andIam______init.(A.interestingB.interested)7.Aftertenyears’hardwork,he______writer.(A.becameB.turned)翻译句子•1.我的兄弟都是中学生。•2.冬季白天短,夜晚长。•3.布朗夫人看起来很健康。•4.十五岁他就成为有名的钢琴家了。•5.孩子们,请保持安静。•6.树叶已经变黄了。•7.这个报告听起来很有意思。answers•1.Mybrothersareallmiddleschoolstudents.•2.Inwinter,thedaysareshortandthenightsarelong.•3.MrsBrownlooksveryhealthy.•4.Attheageoffifteenhebecameafamouspianist.•5.Children,keepquietplease.•6.Theleaveshaveturnedyellow.•7.Thereportsoundsinteresting.填空Thechicken___________.Wouldyouliketohavesome.(味道好)Whentheygothome,they_______________.(感到又饿又冷)单选•1.Arethereanymapsonthewall?___•A.Therearesome.B.Yes,thereis.•C.Yes,thereisone.D.No,thereare.•2.Howmany____arethereinthepicture?•A.womanB.womenC.buyD.milk•3.Therearen’t___treesnearthehouse.Thereisonlyone.•A.anyB.someC.manyD.much•4.There___twobowlsofriceonthetable.•A.isB.haveC.hasD.are•5.Arethere___housesneartheriver?Yes,thereare___.•A.some,someB.any,some•C.any,anyD.some,any用be动词is/are填空1、Thereapencilinthepencilbox.2、Theresomeflowersonthedesk.3、Therefourpeopleinmyfamily.4、Thereapictureandtwomapsonthewall.5、A:thereacatunderthetree?B:Yes,there
