4、s busy.约翰忙.),3)主+动+宾(SVO)例如:(She studies English.她学英语.),4)主+动+宾+补(SVOC)例如:(Time would prove me right.时间会证明我是对的.),5)主+动+间宾+直宾(SVOiOd)例如:(My mother made me a new dress.我母亲给我做了一件新衣裳.),14句子的种类,【句子的种类】(讲解2),疑问句是考试的重点,这里我们先重点讲难掌握的反意疑问句和特殊疑问句.,(1)陈述句部分是肯定式,问句部分一般用否定式,否则反之;前后两部分在人称,数及时态上通常保持一致.如:You are a s

5、tudent,arent you?(你是学生,对吗?),1)反意疑问句:在陈述句之后附上一个简短问句,对陈述句所叙述的事实提出相反的疑问,这种疑问句叫做反意疑问句.,(2)在祈使句后面用反意疑问句,要注意人称的变化.如:Go to the cinema,will you?,(3)在省略的感叹句后面,要注意主语的单复数.如:What fine weather,isnt it?,(4)陈述句部分的主语如是I,疑问部分要用 arent I.如:Im as tall as your sister,arent I?,14句子的种类,【句子的种类】(讲解2),(5)陈述部分用never,hardly,fe

6、w,nothing,nobody,few,seldom,hardly,little等否定含义的词时,疑问部分用肯定含义.如:He seldom came here,did he?,(6)陈述句部分的谓语是used to时,疑问部分用didnt+主语或usednt+主语.如:He used to go to school at seven,didnt he?/usednt he?,(7)陈述部分有had better+v.疑问句部分用hadnt you?如:Youd better read it by yourself,hadnt you?,(8)陈述部分有Youd like to+v.疑问部分

7、用wouldnt+主语.如:Youd like to go with me,wouldnt you?,(9)主语是everyone,someone,anyone,no one等不定代词时,多用they 指代.如:Everyone is here,arent they?(所有的人都来了吗?),14句子的种类,【句子的种类】(讲解2),(10)主语是everything,something,anything,nothing时,用it 指代.省去主语的祈使句的反意疑问句,疑问部分用will you.如:Dont do that again,will you?,注意 Lets 开头的祈使句,后用sha

8、ll we?Let us 开头的祈使句,后用will you?,(11)陈述部分是“there be”结构,疑问部分用there省略主语代词.如:There is something wrong with your watch,isnt there?,2)特殊疑问句:注意疑问词 how many;how much;how often;how old;how long;what;what time;what day;what colour;which;when;who;whose等疑问词的用法.,A.系动词be作谓语:am,is,are/was,were作“提前词”来对应,B.行为动词作谓语:D

9、o/Does/Did作外来助动的“提前词”+主语+动词原形来表达,C.含助动词作谓语:be,do,have,will,shall作“提前词”与相应动词时态来帮助,D.含情态动词作谓语:can,may/must,need/will,shall,would,should作“提前词”+主语+动词原形来强调,14句子的种类,【句子的种类】(讲解3),本讲主要讲一下感叹句、祈使句,再顺便提一下强调句.,1.由what引导的感叹句的基本结构:“What a(an)+形容词+单数名词(+主语+谓语)!”“What+形容词+名词(不可数名词或名词复数)(+主语+谓语)!”.,1)感叹句注意事项:感叹句由wha

10、t和how引导放句前,主语谓语不用变,省掉它们也常见.,2.由how引导的感叹句结构为:“How+形容词或副词(+主语+谓语)!”如:,3.what,how 引导的感叹句有时可以互相转换:What修饰单数可数名词时,如果这一名词有形容词修饰,也可用how引导感叹句,但不定冠词a或an 需放在形容词之后.如:What a large factory=How large a factory it is!如:What a clever boy Jack is!=How clever Jack is!杰克是多么聪明的一个男孩子呀!,14句子的种类,【句子的种类】(讲解3),与let连用的人称代词是第一

11、人称和第三人称的宾格.Let me go.让我去吧.Let him see.让他看看.,2)祈使句注意事项:,注意:Let us可缩写为lets,但两者实际含义不相同.lets用来提建议,听话者与说话者一起去做某事,而let us用来表示请求,即说话者向听话者请求要去做某事。,含有第二人称的祈使句否定中,在动词原形前加dont,不可只用not构成否定.特别是当动词为be时,也用dont,而不可在be后加not.误:Not talk in class.正:Dont talk in class.不要在课堂上讲话.误:Be not late for school.误:Not be late for

12、school.正:Dont be late for school.上学不要迟到.,注意:含有第一、第三人称的祈使句的否定句用Let+not+动词原形或Dont let+第三人称代词的宾格或名词.,14句子的种类,【句子的种类】(讲解3),3)强调句注意事项:,学过的强调句是Tt引导的句子.强调句的连词只有that和who.当强调的部分是人,且为句子的主语时,才用“who”,其余用“that”.句式:It is(was)被强调部分+that(who)+句子其他部分.,注意:此结构强调的成分仅限于主语,宾语和状语.判断一个句子是否是强调句,只需看去掉It be that是否还是一个完整的句子.,典

13、型例题:It is twenty years _ Miss Feng returned to ChinA.A.that B.when C.since D.as,答案C.本题易误选为A(that).其实本句不是强调句.若是,去掉It be that还应是一个完整的句子.而本句去掉“It is.that”,只剩下ten years Miss Feng returned to ChinA.不成句.因此本句不是强调句.,14句子的种类,句子的种类(练习1),1.Dont forget to give the baby some food,_?,A.will you?B.shall we C.wont

31、的第三人称单数形式),宾语a pen.,15句子的结构,【句子的结构】(讲解1),2、主+系+表结构:,(1)主语:同主谓宾结构.,(2)联系动词:be动词(am,is,are,was,were,have been);其他联系动词如:become成为,turn变成,go变.其特点是联系动词与其后的表语没有动宾关系,表语多为形容词或副词,既不可能是宾语.,(3)表语:说明主语的状态、性质等.可为形容词、副词、名词、代词、不定式、分词.当联系动词不是be,而其后是名词和代词时,多表达转变为之意,注意与动宾关系的区别.感官动词多可用作联系动词:look well/面色好,sound nice/听起来

32、不错,feel good/感觉好,smell bad/难闻.,例:Tom is a boy.(Tom是个男孩)主语为Tom,系词为be动词的第三人称单数is,表语为a boy,15句子的结构,【句子的结构】(讲解1),3、There be 结构:,There be 表示存在有.这里的there没有实际意义,不可与副词there那里混淆.此结构后跟名词,表示(存在)有某事物。,试比较:There is a boy there.(那儿有一个男孩.)前一个there无实意,后一个there为副词那里.,(1)There be句式用来表示“某处有某人/某物”,be动词有人称和数变化:主语是可数名词单数

33、或不可数名词,be用is;主语是可数名词复数,be要用are.There is a book on the desk.桌子上有一本书.There is some milk in the bottle.瓶子里有一些牛奶.There are some pictures on the wall.墙上有一此画.,(2)There be结构后面接并列名词短语时,按就近原则其中第一个并列成份决定动词be的单、复数形式.There is a pen and some books on the desk.桌子上有一只钢笔和一些书.There are some books and a pen on the de

34、sk.桌子上有一些书和一只钢笔.,15句子的结构,【句子的结构】(讲解1),(3)There be句式变否定句是在be动词后+not;变一般疑问句是把be作“提前词”放句首,肯定回答要用Yes,there is/are.否定回答要用No,there isnt/arent.There is a ball on the ground.There isnt a ball on the ground.(否定句)Is there a ball on the ground?(一般疑问句)Yes,there is./No,there isnt.,(4)对There be结构的主语提问,无论其是可数名词还是不

35、可数名词,也不论其是单数可数名词还是复数可数名词,都用“What is”.There is some tea in the cup.(对划线部分提问)What is in the cup?There are some desks in the room.(对划线部分提问)What is in the room?,(5)There be句式和have/has都有“有”的意思,但there be句式强调某物所处的位置,而have/has强调某物的归属,即前者强调“存在”,后者强调“拥有”.There is a computer on the table.桌子上有一台电脑.(电脑“存在”于桌上,而不

36、是桌子“拥有”电脑)My uncle has a car.我叔叔有一辆小汽车.(我叔叔“拥有”这辆车),15句子的结构,【句子的结构】(讲解2),二、定语:,定语是对名词或代词起修饰、限定作用的词、短语或句子,汉语中常用的表示.,定语通常位于被修饰的成分前.,若修饰some,any,every,no构成的复合不定代词时,(如:something、nothing);或不定式、分词短语作定语、从句作定语时,则定语通常置后.,副词用作定语时须放在名词之后.,1、形容词作定语:The little boy needs a blue pen.小男孩需要一支蓝色的钢笔.(little修饰名词boy;blu

37、e修饰名词pen.)Tom is a handsome boy.Tom是个英俊的男孩.There is a good boy.有个乖男孩.,15句子的结构,【句子的结构】(讲解2),2、数词作定语相当于形容词:Two boys need two pens.两个男孩需要两支钢笔.The two boys are students.这两个男孩是学生.There are two boys in the room.房间里有两个男孩.,3、代词或名词所有格作定语:His boy needs Toms pen.他的男孩需要Tom的钢笔.His name is Tom.他的名字是汤姆.There are t

42、在句中的某个位置会引起歧义,应注意.如:The boy calls the girl in the classroom.一般理解成男孩喊教室里的女孩(此时in the classroom为girl的定语),也可以理解为男孩在教室里喊女孩(此时in the classroom为地点状语),最好写作In the classroom,the boy calls the girl.,15句子的结构,【句子的结构】(讲解3),1、副词(短语)作状语:The boy needs a pen very much.男孩非常需要一支钢笔.(程度状语)The boy needs very much the pen

46、宾语通常一个指人,为间接宾语;一个指物,为直接宾语.,间接宾语一般位于直接宾语之前.,1、一般的顺序为:动词+间接宾语+直接宾语.如:Give me a cup of tea,please.,2、强调间接宾语顺序为:动词+直接宾语+to+间接宾语.如:Show this house to Mr.Smith.,3、若直接宾语为人称代词:动词+代词直接宾语+to+间接宾语.如:Bring it to me,please.,15句子的结构,【句子的结构】(讲解5),五、宾语补足语:,位于宾语之后对宾语做出说明的成分.宾语与其补足语有逻辑上的主谓关系,它们一起构成复合宾语.,1、名词/代词宾格+名词

50、tudy hard,your score will go up.,解析:错句中分词studying没有自带逻辑主语,则其逻辑主语就是句子的主语,既your score.显然做study的应是人,不应是your score(分数).正确句(1)更正了句子的主语,使其与分词逻辑主语一致(同为you);正确句(2)则使用条件分句带出study的主语,(不过已经不是分词结构了).,15句子的结构,【句子的结构】(讲解7),1、分词独立结构常省略being,having been.不过There being.的场合不能省略.如:Game(being)over,he went home.He stands
