be动词的用法整理.docx

be动词的用法整理1.Be动词有三个，am,is还有are.我用am,你用are,is跟着他她它，复数全部都用are.如果遇到过去时，was来把am,is替，were来把换掉动词are2.do和be动词的用法区别Be动词就是(am，are,is)..句子中如果没有实意动词(例如:write，buy)之类的动词，就直接在主语后面加Be动词。而如果是句子中有实意动词，那么如果你要改为一般疑问句，就要借助DO(do也称为助动词)，例如:Istudy.改为一般疑问句:Doyoustudy?顺口溜：be氏三朵花,am,is还有are,我(I)恋am,你(you)恋are,is跟了他(he)她(she)它(it),单娶is,复娶are。be动词的用法篇二英语的be动词是个用法比较复杂的动词。复杂的原因有两点：1、除了原形的be之外，对于不同人称代词以及单数名词和复数名词，be会有各种变化形式和缩写形式。概括一下有七种形式：be,am,is,are,was,were,been,being。它们与人称代词和名词单、复数的搭配关系是：现在时Iam,youare,he/she/it/is,we/you/theyare;名词单数、不可数名词用is，复数用are。缩略式I'm,you're,he's,we're,you're,they're否定缩略式I'mnot,isn't,aren't过去时Iwas,youwere,he/she/it/was,we/you/theywere;名词单数、不可数名词用was，复数用were。否定缩略式wasn't,weren't过去分词been现在分词being2、在句子中，be有两种主要作用：一是作为系动词(TheLinkingVerb)，本身可以作用谓语动词;二是做为助动词(TheAuxiliaryVerb)，与谓语动词一起构成各种时态和被动语态等。下面做个简要的讲解。be动词的用法：做系动词1、系动词+表语”的结构当be动词做系动词使用时，主要构成“系动词+表语”的结构，在句子中做谓语。表语可以是名词、形容词、副词、介词短语等。例如：Themanisascienceteacher.Mary'snewdressesarecolourful.Motherisinthekitchennow.Ihavebeentherebefore.Theyshallbehereat10:00tommorow.Thatcan'tbetrue.Youarenotbeingverypolite.Yourbrotherisbeingveryannoyingthisevening2、be动词的一般疑问句，方法是把be移到主语前面，也可说成是移到句首。Isthemanascienceteacher?Yes,heis./No,heisn't.AreMary'snewdressescolourful?Yes,theyare./No,theyaren't.Wasmotherinthekitchenthen?Yes,shewas./No,shewasn't.Wereyouathomethedaybeforeyesterday?Yes,Iwas./No,Iwasn't.Wasshelatethismorning?Yes,shewas./No,shewasn't.3、be动词用在特殊疑问句在特殊疑问句里，be动词仍然移到主语前面，但特殊疑问句是以特殊疑问词开头的，所以be动词只能说是移到主语前面，或者说是在特殊疑问词的后面。例如：Whosebikeisbroken?XiaoMing'sbikeis.Whowassingingintheroom?Mr.Zhangwas.Whereareyoufrom?IamfromWuhu.Whatclasswereyouin?WewereinClass2.HowoldisTom?Heisten.4、be动词的否定句be动词做谓语时，它的否定形式是在be后加not，并且可以缩写。例如：Itisnotsunnytoday.Tomandhisfriendsarenotinthepark.YouwerenotnineyearsoldwhenIwenttotheuniversity.Hewasnotoftenlateforhisclasswhenhewasastudent.Iwasn'thereyesterday.Myparentsweren'tathomelastSunday.5、be动词的祈使句be动词的祈使句有肯定和否定两种形式。肯定形式是以be动词开头，而否定形式或强调句形，要加don't或do。例如：Becareful!Beagoodboy!Don'tbesilly!Don'tbeafool!Dobeobedient!D
