英语句型转换一、肯定句、否定句、一般疑问句的相互转换这三种句型的转换有共同的规律可循,有几个要点必须牢记。我们可以把各种句式归为两大类:1、含有的be动词、助动词和情态动词的句子;2、只有行为动词的句子。第1类的句子,肯定句改为否定句时,一律在be动词、助动词和情态动词后加“not”,改为一般疑问句时,一律将be动词、助动词和情态动前移到句首(首字母大写)。肯定回答用“Yes”;否定回答用“No”。“Yes”或“No”后面的主语必须用代词,“No”后面必须用否定缩略式。如:将下列句子改为否定句、一般疑问句,并做肯定、否定回答:1.Therearesomecomputersinthisschool.(be动词)Therearen’tanycomputersinthisschool.Arethereanycomputersinthisschool?(Yes,thereare./No,therearen't.)2.LiMing’sfathercandrivethecar.(情态动词)LiMing’sfathercan’tdrivethecar.CanLiMing’sfatherdrivethecar?(Yes,hecan./No,hecan’t.)3.Shehasalreadyfinishedhishomeworknow.(助动词)Shehasn’tfinishedhishomeworkyet.Hasshefinishedhishomeworkyet?(Yes,shehas./No,shehasn’t.)第2类句子必须借助助动词do;does;did。改为否定句,在行为动词前加don’t(一般现在时态,主语是除第三人称单数之外的人称和数时);doesn’t(一般现在时态,主语是第三人称单数时);didn’t(一般过去时态)。改为一般疑问句时,在句首加Do;Does或Did。肯定回答用“Yes”,后面动词用do;does或did”;否定回答用“No”,后面动词用don’t(doesn’t;didn’t)”。如:将下列句子改为否定句、一般疑问句,并做肯定、否定回答:1.Thechildrenlikeplayinggames.Thechildrendon’tlikeplayinggames.Dothechildrenlikeplayinggames?(Yes,theydo./No,theydon’t.)2.Maryusuallygoestoschoolonfoot.Marydoesn’tusuallygotoschoolonfoot.(原第三人称单数改为原形)DoesMaryusuallygotoschoolonfoot?(Yes,shedoes./No,shedoesn’t.)3.TomwenttoLondonyesterday.Tomdidn’tgotoLondonyesterday.(原过去式改为原形)DidTomgotoLondonyesterday?(Yes,hedid./No,hedidn’t.)二、特殊疑问句的转换把句子转换为特殊疑问句,首先要确定划线部分的“疑问词”,人、物、时间、地点、数量、原因等分别用:who;whose;whom;what;when;where;why;how;howmany;howmuch;howoften;howold;howlong等。将相对应的疑问词放在句首,其余部分改为一般疑问句的形式,就是特殊疑问句。改完后要注意检查句首的首字母大写和句尾的标点符号。如:1.Hislicencenumberis573968.What’syourlicencenumber?2.MikewatchesTVeveryevening.WhatdoesMikedoeveryevening?3.JimstudiedinChinalastyear.WheredidJimstudylastyear?三、选择疑问句、反意疑问句的转换改为选择疑问句时,只需注意根据句子的内容用“or”连接两个并列的成分就可以了。如:Lucyisastudent,Lilyisadoctor.改为:Whoisadoctor,LucyorLily?反意疑问句的结构是“陈述句+简短问句”,我们必须记住:“前面肯定;后面否定”和“前面否定;后面肯定”的规律和简短问句的主语必须用代词的要求。如:Tomlikesplayingfootball,_____doesn’the_____?XiaoHongdidn’tlikesinging,______didshe_____?注意:祈使句的反意疑问句,一般都用willyou?Let’s---打头的一般用shallwe?四、祈使句、感叹句的转换改为祈使句,必须记住:肯定的祈使句,是原形动词开头,否定的祈使句是“Don’t”开头,后跟动词原形。如:1.Youshouldrememberhistelephonenumber.改为:Rememberhistelephonenumber,please.2.You’dbetternottellhimthebadnews.改为:Don’ttellhimthebadnews.3.Wecangotheretogether.改为:Let’sgotheretogether.3.JimstudiedinChinalastyear.WheredidJimstudylastyear?3.JimstudiedinChinalastyear.WheredidJimstudylastyear?改为感叹句,必须记住,强调的是名词,句首用What,What后的名词前可以有形容词;强调的是形容词、副词,句首用How,后面必须紧跟形容词、副词,如Theparkisbeautiful.改为:Whatabeautifulpark!或:Howbeautifultheparkis!HestudiesEnglishveryh...
