be动词专项练习

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Im。如：ImDavid.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=Were，Theyare=Theyre,Youare=Youre。而are与not可缩写成arent。如：Theyarentstudents.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=Hes,Mymotheris=Mymothers等。但是Thisis不可缩写。而is与not可缩写成isnt。如:Thisisntabook.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：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.,am,are,is,is,are,are,am,is,are,Is,11.Hersisteranurse.12.Theymygoodfriends.13.Hemybrother.14.Sheten.15.Hismotheranactress.16.It_acat.17.Theapples_nice.18.This_acat.19.Thecat_funny.20.Thedogs_funny.,is,are,is,is,is,is,is,is,are,are,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：,Iamnotateacher.,Areyouateacher?,Yes,Iam.,No,Iamnot.,Theyarenotnewstudents.,Aretheynewstudents?,Yes,theyare.,No,theyarenot.,arent,Heisnotagoodboyathome.,Isheagoodboyathome?,Yes,heis.,No,heisnt,4.BobisinClassOne,GradeSix.否定句：一般疑问句：肯定回答：否定回答：5.Iamagoodstudentatschool.否定句：一般疑问句：肯定回答：否定回答：,BobisnotinClassOne,GradeSix.,IsBobinClassOne,GradeSix?,Yes,heis.,No,heisnt,Iamnotagoodstudentatschool.,Areyouagoodstudentatschool?,Yes,Iam.,No,Iamnot.,7.WearehavinganEnglishclass.否定句：一般疑问句：肯定回答：否定回答：8.Itissunnytoday.否定句：一般疑问句：肯定回答：否定回答：,WearenothavinganEnglishclass,AreyouhavinganEnglishclass?,Yes,weare,No,wearent,Itisnotsunnytoday.,Isitsunnytoday？,Yes,itis,No,itisnt,单项选择1.Doyouoftenplayping-pong?_.A.Yes,IdontB,No,IdoC.Yes,Ido2.WhatdoyouhaveonFridays?A.IhavescienceB.IWatchTVC.Yes,Ido3.WhatdoyoudoonFridays?A.IgotoschoolB.IhavescienceC.Yes,Ido4._IhaveEnglishandPEonFridays.A.WhatdoyoudoonFridays?B.WhatdoyouhaveonFridays?C.Whatdayisittoday?,c,A,A,B,5._Ihaveacookingclass.A.WhatdoyouhaveonWednesdays?B.Whatdayisit?C.Whattimeisit?6._ItsMondaytoday.A.Whatdayisittoday?B.WhatdoyouhaveonMondays?C.Whattimeisit?7._Its8:00now.A.Whattimeisit?B.WhatdoyouhaveonMondays?C.Whatdayisit?,A,A,A,Whatdoyouoftendoontheweekend?,Whatdoyouoftendoontheweekend?,No,Idont.,Doyouoftenlistento
