小学英语句型专项归类1.肯定句:是指用肯定的语气来陈述的句子.2,否定句:含有否定词或表示否定意义词的句子.例I'mastudent.I'mnotastudent.Sheisadoctor.Sheisnot(isn't)adoctor.Heworksinahospital.Hedoesnot(doesn't)workinahospital.Therearefourfansinourclassroom.Therearenot(aren't)fourfansinourclassroom.Hewilleatlunchat12:00.Hewillnot(won't)eatlunchat12:00.IwatchedTVyesterdayevening.Ididnot(didn't)watchTVyesterdayevening.☆注意☆小结:否定句主要是在肯定句的基础上加上了否定词"not"。有动词be的句子则"not"加在be后面，可缩写成"isn't，aren't"，但amnot一般都分开写。没有动词be的句子，则要先在主要动词的前面加上一个助动词(do,does,did)，然后在它后面加上"not"。你也可以把它们缩写在一起，如"don't,doesn't,didn't).。这三个助动词要根据人称和时态来选择，其中"does"只用于一般现在时主语是第三人称单数的情况，而"did"只用于一般过去时，不论主语是什么人称和数，用"did".。3,一般疑问句:是指询问事实的句子,此类句子必须用"yes",或"no"来回答.如:Areyouastudent？Yes,Iam/No,I'mnot.Issheadoctor？Yes,sheis./No,sheisn't.Doesheworkinahospital？Yes,hedoes./No,hedoesn't.Aretherefourfansinourclassroom？Yes,thereare./No,therearen't.Areyougoingtobuyacomicbooktonight？Yes,Iam./No,Iamnot.(Yes,weare./No,wearen't.)Willheeatlunchat12:00？Yes,Iwill./No,Iwillnot(won't).Aretheyswimming？Yes,theyare./No,theyaren't.DidyouwatchTVyesterdayevening？Yes,Idid./No,Ididn't.☆注意☆小结:一般疑问句是在肯定句的基础上,①把动词be调到首位,其他照写,末尾标点符号变成问号即可.②没有动词be的句子则要在句首加上一个助动词(do,does,did)再把紧跟在后面的动词变回原形,末尾标点符号变成问号即可.这三个助动词也要根据人称和时态来选择,其中"does"只用于一般现在时主语是第三人称单数的情况。而"did"只用于一般过去时,不论主语是什么人称和数,都用"did"。一般疑问句有个重要的原则，就是问和答要一致，即问句里的第一个单词(助动词)和简略答句里的这个词是一致的.4,特殊疑问句:以特殊疑问词(what,where,who,which,when,whose,why,how等)开头引导的句子.此类句子应该问什么就答什么,不能用"yes,no"来回答.如:Whatisthis?It'sacomputer.Whatdoeshedo?He'sadoctor.Whereareyougoing?I'mgoingtoBeijing.Whoplayedfootballwithyouyesterdayafternoon,Mike?Whichseasondoyoulikebest?Summer.Whendoyouusuallygetup?Iusuallygetupat6:30.Whoseskirtisthis?It'sAmy's.Whydoyoulikespringbest？BecauseIcanplanttrees.Howareyou？I'mfine./I'mhappy.HowdidyougotoXinjiang？IwenttoXinjiangbytrain.☆其中how又可以和其他一些形容词连用组成特殊疑问词组用来提问,如:howmany(多少/数目),howmuch(多少/钱)),howtall(多高),howlong(多长),howbig(多大),howheavy(多重)例句:Howmanypencilsdoyou？haveIhavethreepencils.Howmanygirlscanyousee？Icanseefourgirls.Howmanydesksarethereinyourclassroom？There
