一般现在时知识点总结一、本次知识点归纳:表达经常性或习惯性的动作、状态、表示真理或客观事实。二、重要知识点提示:一般现在时需要表示经常性的时间状语例如:always、usually、often、sometimes、everyday、inthemorning/afternoon/evening、onSundays等。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.Iam还可缩写成I'mam与not不能缩写。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?are与主语还可缩写。如:We're,They're,You're。而are与not可缩写成aren't3.如果主语是单数名词、不可数名词或第三人称单数代词(he,she,it)时,be动词用is。如:Mymotherisateacher.is也可与主语缩写,如:He's,Mymotheris=Mymother's等。但是Thisis不可缩写。而is与not可缩写成isn't4.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。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.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:我用am,你用are,is跟着他(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。三、Therebe句型1、Therebe的固定句型:Therebe+某物/某人+介词+某地表示:在某地有某物(或人)2、在therebe句型中,主语是单数,be动词用is;主语是复数,be动词用are;如有几件物品,be动词根据最靠近be动词的那个名词决定。3、therebe句型的否定句在be动词后加not,一般疑问句把be动词调到句首。4、therebe句型与have(has)的区别:therebe表示在某地有某物(或人)have(has)表示某人拥有某物三、经典题训练过关:基础练习一.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、句型转换1、Thecatisbeautiful.2、Hersistersarestudents.→否定句:→一般疑问句:→肯定/否定回答:三、用“have,has”or“thereis,thereare”填空1.I________agoodfatherandagoodmother.2.____________atelescopeonthedesk.3.He_________atape-recorder.4._____________abasketballintheplayground.5.She__________somedresses.6.They___________anicegarden.7.Whatdoyou___________?8.______________areading-roominthebuilding?9.WhatdoesMike___________?10.______________anybooksinthebookcase?11.Myfather_________astory-book.12._______________astory-bookonthetable.13._______________anyflowersinthevase?14.Howmanystudents____________intheclassroom?15.Myparents___________somenicepictures.16._____________somemapsonthewall.17.______________amapoftheworldonthewall.18.David__________atelescope.19.David’sfriends___________sometents.20.______________manychildrenonthehill.巩固练习一、用be的适当形式填空1.---How____you?---I____fine.2.I___David,andmyfamilyname___Green.3.---Whatcolor___yourclock?---It___white.4.---What___thisinEnglish?---It___anapple.5.Toy___mybrother.David____mybrother,too.They___mybrothers.6.Look!These____appletrees.7.We____goodstudentsandyou____goodteacher.8.Mysisterandmybrother_____students.9._____theremanyeggsinthekitchen?10.____yourcardnumber5578?11.Where_____yourpencils?12.Thesesweaters______fiftydollars.13.Howmuch____hisjacket?14.Mybrother’sbirthday____December11th.15.When_____Kate’sbirthday?16、There_____aboyandtwogirlsbesidethegate.17、Fiveandthree____eight.二、将下面的句子变成一般疑问句并作出回答1.Thatismyfootball.2.Thosearehisbooks.3.JimandTomaregoodfriend.4.MybirthdayisNovember1st.5.Hissonistwelveyearsold.三、将下面的句子变成否定句1.Hiscardisonthetable.2.Thesearemyparents.3.BobandTonyareourfriends.4.Thesethingsarefivedollars.5.Thegirlishissister.四、改写句子1.Iamateacher.2.Theyarenewstudents.否定句:一般疑问句:肯定回答:否定回答:3.Heisagoodboyathome.4.WearehavinganEnglishclass.否定句:一般疑问句:肯定回答:否定回答:5.BobisinClassOne,GradeSix.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:
