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

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

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

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

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
