Be动词专项练习be动词的一般现在时有三种形式,即:am,is,are(翻译为“是”)1.如果主语是第一人称I(我)时,be动词用am。如:Iamastudent.我是一名学生。Iam还可缩写成I'm。如:I'mDavid.我是大卫。am与not不能缩写。如:Iamnotabadboy.2.如果主语是you(你,你们),they(他们,它们,她们)或名词复数(两个以上的人或物)时,be动词必须用are。如:Areyoutwelve?你是十二岁吗?TomandLilyaregoodfriends.汤姆和莉莉是好朋友。Theyareatschool.他们在学校。are与主语还可缩写。如:Weare=We're,Theyare=They're,Youare=You're。而are与not可缩写成aren't。如:Theyaren'tstudents.他们不是学生。3.如果主语是单数名词、不可数名词或单数第三人称代词(he,she,it)时,be动词用is。如:Mymotherisateacher.我的妈妈是一名老师。Heisastudent.他是一名学生。is也可与主语缩写,如:Heis=He's,Mymotheris=Mymother's等。但是Thisis不可缩写。而is与not可缩写成isn't。如:Thisisn'tabook.这不是一本书。4.句中含有be动词的陈述句变一般疑问句。把be动词提到句首,be动词要变大写。注意第一人称变第二人称。回答时用yes或no表示,结构:Yes,主语+be动词,No,主语+be动词+not。如:Itisabook.变为:Isitabook?5.句中含有be动词的肯定陈述句变否定句。先找肯定陈述句中的be动词,在be动词后加not.如:Itisabook.变为:Itisnotabook.根据以上叙述我们可以把动词的用法以口诀的形式表述出来:我(I)用am,你(you)用are,is连着他(he),她(she),它(it);单数名词用is,复数名词全用are。变疑问,往前提,句末问号莫丢弃。变否定,更容易,be后not莫忘记。疑问否定任你变,句首大写莫迟疑。Be动词用法练习题:一.选择正确的be动词填空1.I____astudent.2.We____friends.3.He____agoodboy.4.She____mysister.5.They____myparents.6.You____11yearsold.7.Iadoctor.8.Myfatherapoliceman.9.Wehavingbreakfast.10.TomfromCanada.11.Hersisteranurse.12.Theymygoodfriends.13.Hemybrother.14.Sheten.15.Hismotheranactress.二.用适当的be动词填空1.Iaboy.youaboy?No,Inot.2.ThegirlJack’ssister.3.yourbrotherintheclassroom?4.WhoI?5.Thejeansonthedesk.6.Thereagirlintheroom.7.Mysister’snameNancy.8.Theresomeapplesonthetree.9.Thereaboy,twogirls,threemenandtenwomeninthepark.10.Thedogtallanfat.11.Themenwithbigeyesourteacher.12.Whereyourmother?Sheathome.13.Howoldyourfather?14.MikeandBobatschool.15.Whosedressthis?16.Whosesocksthey?17.Thatmynewbook.18.Hereascarfforyou.19.Heresomebananasforyou.20.TheblackglovesforPeter.21.Thispairofshoesforyou.22.Therefourbottlesofmilkonthetable.23.Someteaintheglass.24.DavidandHelenfromEngland?25.thereanydictionariesintheclassroom?26.thereanyapplejuiceinthebottle?27.Theresomebreadontheplate.28.You,heandIfromChina.29.Heretwopensandonebook.30.yourfriendsinBeijing?三.改写句子1.Iamateacher.否定句:一般疑问句:肯定回答:否定回答:2.Theyarenewstudents.否定句:一般疑问句:肯定回答:否定回答:3.Heisagoodboyathome.否定句:一般疑问句:肯定回答:否定回答:4.WearehavinganEnglishclass.否定句:一般疑问句:肯定回答:否定回答:5.BobisinClassOne,GradeSix.否定句:一般疑问句:肯定回答:否定回答:6.SheisformJinan.否定句:一般疑问句:肯定回答:否定回答:7.Iamagoodstudentatschool.否定句:一般疑问句:肯定回答:否定回答:8.Theyareintheteacher’soffice.否定句:一般疑问句:肯定回答:否定回答:9.Hisfatherisapostman.否定句:一般疑问句:肯定回答:否定回答:10.Wearedoingourhomework.否定句:一般疑问句:肯定回答:否定回答:11.Sheisasinger.否定句:一般疑问句:肯定回答:否定回答:12.Theyarereadingbooks.否定句:一般疑问句:肯定回答:否定回答:13.Iamasmartboy.否定句:一般疑问句:肯定回答:否定回答:14.Thereisadogoverthere.否定句:一般疑问句:肯定回答:否定回答:15.Therearealotofgeeseinthefarm.否定句:一般疑问句:肯定回答:否定回答:16.Hisbrotherisagood-lookingboy.否定句:一般疑问句:肯定回答:否定回答:17.Wearefriends.否定句:一般疑问句:肯定回答:否定回答:18.Itissunnytoday.否定句:一般疑问句:肯定回答:否定回答:
