be动词详解及精选练习题150道

be动词是我们必须掌握的一个重要概念，虽然be动词少，但是由于其形式多变，给很多同学的英语学习造成了一定的困难，下面主要就be动词作一个专题复习。1.be动词的概念：be动词是系动词的一种，是与一般动词（实义动词）相区别的概念。一般动词表示具体的动作。而be动词不是动作，它通常与名词、形容词或其它词类一起表示主语的性质、状态、身份、特点等等。一般动词很多，如：walk(走)、read(读)、stand(站立)等等，而be动词只有一个，那就是be，所以它称为be动词。be动词在不同的句子中有不同的中文意义，有时甚至不用翻译其意义。be动词有不同的形式，如：现在式有am,are,is三种，过去式有was和were两种，过去分词只有been一种形式。2.be动词的现在式用法：be动词的现在式有am,are,is三种，具体用哪一种，必须由主语的人称和数决定。如下表所示：be动词用法歌：动词用法歌：我用am,你用are，is连接他，她，它。你用，连接他，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。变疑问，往前提，句末问号莫丢弃。变否定，更容易，莫忘记。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。疑问否定任你变，句首大写莫迟疑。3.be动词的过去式用法：be动词的过去式是：was和were,这两种形式与现在式用法没有多大区别，作谓语时用哪一种，还是由主语的人称和数决定。如(3)疑问句：be动词+主语……如：(a)一般疑问句及其回答：Areyouastudent?回答：Yes,Iam.No,Iamnot.注意：含be动词的一般疑问句回答用Yes或No.其结构是：Yes,+主语+be动词/No,+主语+be动词+not.(b)特殊疑问句：Whatisyourname?Howareyou?Whereismypencil-box?4.Therebe句型：therebe句型是含有be动词的一个重要句型。其结构如下：there+be动词+名词+地点状语Thereisaschoolthere.那里有一个学校。在这个句型中aschool是真正的主语，be动词的形式由它决定。当这个名词是单数时，be动词是is或was,当这个名词是复数时，be动词用are或were。如：Therearemanystudentsintheclassroom.在教室里有许多学生Therewasanaccidentinthestreetlastnight.昨晚这街上有个车祸。TherewerelotsofpeopleintheroomwhenIgotin.当我进去的时候，屋里有很多人。therebe句型的一般疑问句是将be动词提前，否定句也是将be动词后面加上not,如：Isthereanywaterinthebottle?瓶子里有一些水吗？Therearen’tanystudentsintheroom.房间里没有任何学生。【练习题】一.用括号中适当的词填空。1.I________fromAustralia.2.She_______astudent.3.JaneandTom_________myfriends.4.Myparents_______verybusyeveryday.6.I______anEnglishteachernow.7.Where_________youfrom?10.Thelight_________green.11.Mynameis_________LiDong.I_________twelve.12._________theyyournewfriends?13.I______aboy.______youaboy?No,I_____not.14.Thegirl______Jack'ssister.15.Thedog_______tallandfat.16.______yourbrotherintheclassroom?17.Where_____yourmother?She______athome.18.Whosedress______this?19.That______myredskirt.20.Who______I?21.Sometea______intheglass.22.Gaoshan'sshirt_______overthere.23.Mysister'sname______Nancy.24.This______notWangFang'spencil.25.______DavidandHelenfromEngland?26.We____friends.27.She___ateacher.28.I___agirl.29.Manyants____inmyhouse.30.Hismother____fat.31.He_____inClass4,Grade1.32.What_____yourname?33.These_____buses.34.Whatclass_____youin?35.It_____acar.36.Helen____astudent37.This_____mybook.38.Myfather______acook.39.Jack’sfriend____inClassOne.40.You____adoctor.41.They____cars.42.That______herdog.43.Thecat_______onthedesk.44.Thebooks_______underthetable.45.I________(am,are,is)fromAustralia.46.She_______(am,are,is)astudent.47.JaneandTom_________(am,is,are)myfriends.48.Myparents_______(am,is,are)verybusyeveryday.49._______(Are,Is,Do,Does)thereaChineseschoolinNewYork?50.There_____(be)someglassesonit.51.Ifhe_____(be)freetomorrow,hewillgowithus.二.用be动词的适当形式填空。1.A:Where_______thepostoffice.------B:It________behindthebuilding.2.A:_______youmissBlack?-----B:Yes,I______.3.It_____ashirt,it_______(not)askirt.4.There________abigplaygroundinourschool.5.There______manybooksinmyschoolbag.6.There_________somefishinthebox.7._______thereanychairsintheclassroom?8.You’dbetter_______earlynexttime.三、用am,is,are填空1.I______aboy.______youaboy?2.Thegirl______Jack'ssister.3.Thedog_______tallandfat.4.Themanwithbigeyes_______ateacher.5.______yourbrotherintheclassroom?6.Where_____yourmother?7.How_______yourfather?8.MikeandLiuTao______atschool.9.Whosedress______this?10.Whosesocks______they?11.That______myredskirt.12.Who______I?13.Thejeans______onthedesk.14.Here______ascarfforyou.15.Here______somesweatersforyou.16.Theblackgloves______forSuYang.17.Thispairofgloves______forYangLing.18.Thetwocupsofmilk_____forme.19.Sometea______intheglass.20.Gaoshan'sshirt_______overthere.21Thedog_______tallandfat.40.Themanwithbigeyes_______ateacher.41.______yourbrotherintheclassroom?42.Where_____yourmother?She______athome.43.How_______yourfather?44.MikeandLiuTao______atschool.45.Whosedress______this?46.Whosesocks______they?47.That______myredskirt.48.Who______I?49.Thejeans______onthedesk.50.Here______ascarfforyou.51.Here______somesweatersforyou.52.Theblackgloves______forSuYang.53.Thispairofgloves______forYangLing....54.This______notWangFang'spencil.She______athome.No,I_____not.55.______DavidandHelenfromEngland?56.There______agirlintheroom.57.There______someapplesonthetree.58._______thereanykitesintheclassroom?59._______thereanyapplejuiceinthebottle?60.There_______somebreadontheplate.四.选择1.She______MissHen.A.beB.amC.is2.I______sorry.A./B.amC.are3.Here______myball.A.isB.areC.am4.You______numbereight.A.areB.isC.am5.What_______this？A.isB.areC.be6.Helen____astudent.A.beB.amC.is7.Those_____oranges.A.isB.areC.am8.Howold_____yourteacher?A.beB.amC.is9.Where_____hermother?A.areB.isC.am10.Thetwocupsofmilk_____forme.A.isB.areC.be11.EricandKathy____mystudents.A.areB.isC.am12.Yourbooks____notgood.A.isB.areC.be13.He___aboy.A.beB.amC.is14.It___mydog.A.isB.areC.be15.Whosesocks______they?A.areB.isC.am16._______thereanychairsintheclassroom.A.IsB.AreC.Am17.Themanwithbigeyes_______ateacher.A.beB.amC.is18.How_______yourfather?A.isB.areC.be19.MikeandLiuTao______atschool.A.areB.isC.am20.I_____astudent.A.beB.amC.is21.They______teachers.A.isB.areC.be22.This_____mymothe
