初一英语am-is-are及练习题

课时一amisare一、重点语法1.动词be（am,is,are）的用法：be动词包括“am”,“is”,“are”三种形式。①第一人称单数(I)配合am来用。句型解析析：Iam+…例句：IamSnoopy.Iamtenyearsold.Iamastudent.Iamaboy.②第二人称(You)配合are使用。句型解析：Youare+…例句：Youaremygoodfriend.Youareagoodteacher.Youarebeautiful③第三人称单数(HeorSheorIt)配合is使用。句型解析：She(He,It)is+……例句：Sheisagoodgirl.Sheissotall.Sheisshort.④人称复数(we/you/they)配合are使用。句型解析：We(You,They)are+……例句WeareinClass5,Grade7.Theyaremyfriends.Youaregoodstudents.二、Be动词在一般过去时中的变化：1．am和is在一般过去时中变为was。（wasnot=wasn’t）2．are在一般过去时中变为were。（werenot=weren’t）3．带有was或were的句子，其否定、疑问的变化和am,is,are一样，即否定句在was或were后加not，一般疑问句把was或were调到句首。am,is,are的注意事项1.is和are可分别与not缩写为isn’t和aren’t，但am却不能与not缩写为amn’t，虽然有人把它缩为ain’t，但这毕竟是规范的口语说法，不宜仿用。2.陈述部分为第一称肯定式时的反意疑问句，通常用aren’t如：I’mlate,aren’tI?我迟到了，是吗？3.不要认为在主语之后总是用am。试看：BothheandIareright.他和我都对。或他和我都不对。NeitherhenorIam(或are)right.他和我都不对.IisanEnglishletter.I是英语字母。4.当am,isare位于句末时，均不能与主语缩写。如：Tellmewhereheis(不能用he’s)。告诉我他在哪儿。HeistallerthanIam(不能用I’m)。他比我高。A：AretheywatchingTV?他们在看电视吗？B：Yes,theyare.(不能用they’re)是的。注：若其后有not时，am,is,are则可以与主语缩写，其中is和are也可与not缩写。如：AretheywatchingTV?-No,they’renot(或theyaren’t).用法口诀：我(I)用am,你(you)用are，is跟着他(he)，她(she)，它(it)。单数名词用is，复数名词全用are。变否定，更容易，be后not加上去。变疑问，往前提，句末问号莫丢弃。还有一条须注意，句首大写莫忘记。一.用括号中适当的词填空。1.I________(am,are,is)fromAustralia.2.She_______(am,are,is)astudent.3.JaneandTom_________(am,is,are)myfriends.4.Myparents_______(am,is,are)verybusyeveryday.5._______(Are,Is,Do,Does)thereaChineseschoolinNewYork?6._______(Be,Are,Were,Was)theyexcitedwhenheheardthenews?7.There_____(be)someglassesonit.8.Ifhe_____(be)freetomorrow,hewillgowithus.一、用be动词的适当形式填空1.I___am___aboy.__are____youaboy?No,I_am____not.2.Thegirl__is____Jack'ssister.3.Thedog___is____tallandfat.4.Themanwithbigeyes___is____ateacher.5.___is___yourbrotherintheclassroom?6.Where__is___yourmother?She___is___athome.7.How_is______yourfather?8.MikeandLiuTao__are____atschool.9.Whosedress___is___this?10.Whosesocks___are___they?11.That___is___myredskirt.12.Who__am____I?13.Thejeans__are____onthedesk.14.Here___is___ascarfforyou.15.Here__are____somesweatersforyou.16.Theblackgloves___is__forSuYang.17.Thispairofgloves__are____forYangLing.18.Thetwocupsofmilk__are___forme.19.Sometea___are___intheglass.20.Gaoshan'sshirt___is____overthere.21.Mysister'sname__is____Nancy.22.This__is____notWangFang'spencil.23.____are__DavidandHelenfromEngland?24.There__is____agirlintheroom.25.There___are___someapplesonthetree.26.__are_____thereanykitesintheclassroom?27.___is____thereanyapplejuiceinthebottle?28.There____are___somebreadontheplate.29.There___are____aboy,twogirls,threemenandtenwomeninthepark.30.You,heandI__are____fromChina.
