1.Be动词的形式:be现在过去单数is/amwas复数arewere分词beingbeenBe动词口诀:我用am,你用are,is用于他、她、它。单数用is,复数用are。指示代词作主语,This,that用is,These,those要用are。若是变为否定句,Not系动词后面加。若变一般疑问句,句首Am,Is,Are,句末问号莫忘加。回答一般疑问句,Yes,或No简回答。另外:我们还会碰到Be动词的动词不定式:tobe,接下来我们来练练手吧(光说不练假把式嘛):Iamsorryformy______latetoday.Ihaven’t______lateforalongtime.Youmust______hereontimenexttime.Iexpectyou______apunctualperson.答案:Iamsorryformybeinglatetoday.Ihaven’tbeenlateforalongtime.(原句意思是“很抱歉我今天迟到了。我很长时间没迟到了。”所以这句话可别随便和你的老师说喔,不然老师一定会抽死你的。阴笑ing…)Youmustbehereontimenexttime.Iexpectyoutobeapunctualperson.2.Be动词的简写形式和否定形式:简写形式:be动词的否定形式:be动词否定形式的简写:Iam=I’mIamnot…Iam…=I’mnot…Youare=You’reYouarenot…Youarenot…=You'renot…=youaren't…Sheis=She’sSheisnot…Sheisnot…=She'snot…=sheisn't…注:如果be动词前有别的助动词的时候,要在be动词前面进行否定。换句话说当be动词是be,tobe,being,been的形式时,否定都是在前面加not。例如:Itwillnotbethateasy.Itcouldn’tbebetter.3.Be动词的进阶:(1)时态:进行时bedoing=amisare/wasweredoing例句:Sheiswritingaletternow.Iwassleepingatthattime.(2)语态bedone(可以和各种时态结合)例句:Iambadlypaid.Hewaskilledinanaccident.Heisappointedasthemanagerofthisdepartment.(3)词缀be-形容词:belovedadj.敬爱的,受到爱戴的belateda.迟来的benightedadj愚昧无知的,落后的动词:belittlevt.轻视,使渺小bemoanvt.惋惜;为…叹息4.涉及的句型:(1)祈使句:肯定:Bequiet,please.Becarefull.否定:Don’tbenervous.Don’tbelate.Don'tbetooserious.(2)Therebe结构:Thereisapenandtwobooksonthedesk.Therearetwobooksandapenonthedesk.5.句子赏析Beyourself.I'llalwaysbethereforyou.Leaveherbe,sheobviouslydoesn’twanttotalkaboutit.Tobeornottobe,that’sthequestion.【总结】虽然be动词很短小,但却很强悍,在英语各大语法重点中都有它的身影,如时态,语态,虚拟语气,反义疑问句,强调句,定语从句,倒装等语法现象,所以大家要好好掌握它的用法。
