七年级英语第三人称单复数专项练习（完整版）资料(可以直接使用，可编辑优秀版资料，欢迎下载）教学目标掌握第三人称的用法重点、难点什么叫第三人称单数、第三人称单数的变化规律考点及考试要求什么叫第三人称单数、第三人称单数的变化规律教学内容哪些主语属于第三人称单数哪些主语属于第三人称单数哪些主语属于第三人称单数哪些主语属于第三人称单数?一般现在时中，当主语是第三人称单数时，谓语动词要用第三人称单数形式。其实主语是第三人称单数，主要有以下几种情况：1.不可数名词作主语。如：Somewaterisintheglass.水在玻璃杯里。2.单个的可数名词作主语。如:ThegirlisAmerican.这个女孩是美国人。Mywatchisonthedresser.我的手表在梳妆台上。3.he,she,it等代词单独作主语。如:Heisinthetree.他在树上。Shelikesherfamilyverymuch.她非常喜欢她的家。4.单个的人名、地名或称呼作主语。如：Tonyisadoctor.托尼是一位医生。UncleLispeaksalittleEnglish.李叔叔会说一点儿英语。Gaochengisabeautifultown.藁城是一座美丽的城镇。5.指示代词this,that等作主语。如：Thisisapear.Thatisanapple.这是一个梨，那是一个苹果。6.everyone,everything,somethingnobodynothing等不定代词作主语时。如：Iseveryoneheretoday?今天大家都到齐了吗？Nobodycananswerthequestion.没有人能回答出这个问题。7.单个数字作主语时。如：“8”词尾变化规则：1.一般情况下，直接在动词词尾+s，例如：get→gets;take→takes2.以s,sh,ch,x,o结尾的动词，在词尾+es，例如：teach→teaches;fix→fixes;go→goes3.以辅音字母+y结尾的动词，变y为i，再+es，如：study→studies;try→tries除上述规律外除上述规律外除上述规律外除上述规律外，还应注意下面三点还应注意下面三点还应注意下面三点还应注意下面三点：1.动词have遇到主语是第三人称单数时，要用has；动词be的第三人称单数形式是is。2.含有动词第三人称单数形式的句子变否定句时，要用doesn't+动词原形，Hegoestoschoolatsixinthemorning.(否)→Hedoesn'tgotoschoolatsixinthemorning.3.对含有动词第三人称单数形式的句子提问时，要用助动词does，如：Shegoeshomeatfiveeveryday.(对划线部分提问)→When/Whattimedoesshegohomeeveryday?综上所述，只要我们洞悉了英语动词第三人称单数形式的变化规则，在一般现在时的句子中，我们都能从容应对，客随主“变”了。【发音规律】动词原形变第三人称单数的规则与发音规律同名词单数变复数大致相同，请认真观察。1、大多数动词在词尾加“S”在清辅音后发音为[s]，在浊辅音及元音后发音为[z]。如①stop－stops[s];make－makes[s]②read－reads[z];play－plays[z]2、以辅音字母加“y”结尾的，要先将“y”变为“i”，然后在加“es”读[iz]如：fly－flies[z]；carry－carries[z]study－studies[z];worry－worries3、以“s,x,ch,sh”结尾的，在词尾加“es”，发音为[iz]如：teach－teaches[iz];watch－watches[iz]4、以“o”结尾的动词，加“es”，读[z]如go－goes[z]do－does[z]下面几个动词变为单数时，原词的元音部分的发音发生了较大的变化，请注意记忆。如1、do[du:]－does[dz]2、say[sei]－says[sez]以不发音字母“e”结尾的开音节词，如果尾音是[s]，[z]时，加“s”后字母“e”发音，与所加“s”一起读做[iz]。如：close－closes[iz]但有些同学们对于哪些主语是第三人称单数还不十分清楚，现归纳总结如下：一、人称代词he,she,it是第三人称单数。如：HelikeswatchingTV.他喜欢看电视。Shehaslunchattwelve.她十二点吃午餐。Itlookslikeacat.它看起来像只猫。二、单个人名、地名或称呼作主语；是第三人称单数。如：①HanMeilookslikeherm韩梅看起来像她的母亲。②BeijingisinChina.北京在中国。③UncleWangoftenmakescakes.王叔叔经常做蛋糕。三、单数可数名词或"this/that/the+单数可数名词"作主语时，是第三人称单数。如：①Ahorseisausefulanimal.马是有用的动物。②Thisbookisyours.这本书是你的。③Thatcarisred.那辆小汽车是红色的。④ThecatisLucy's.这只猫是露茜的。四、不定代词someone,somebody,nobody,everything,something等及指示代词this,that作主语时，是第三人称单数。如：①Everyoneishere.大家到齐了。②Thereissomethingwrongwiththewatch.这块手表有毛病。③Thisisapen.这是一支钢笔。④Thatisaneraser.那是一块橡皮擦。五、不可数名词作主语时为第三人称单数。如：①Themilkisintheglass.牛奶在玻璃杯里。②Thebreadisverysmall.那面包很小。六、当数字或字母作主语时，看作第三人称单数。如：①"6"isaluckynumber."6"是个吉利数字。②"I"isaletter."I"是个字母三、家庭作业一、写出下列动词的第三人称单数drink________go_______stay_______make________look________have_______pass_______carry________come_______watch______plant_______fly________study_______brush________do________teach_______二、用括号内动词的适当形式填空。1.Heoften________(have)dinnerathome.2.DanielandTommy_______(be)inClassOne.3.We_______(notwatch)TVonMonday.4.Nick_______(notgo)tothezooonSunday.5.______they________(like)theWorldCup?6.What_______theyoften_______(do)onSaturdays?7._______yourparents_______(read)newspaperseveryday?8.Thegirl_______(teach)usEnglishonSundays.9.SheandI________(take)awalktogethereveryevening.10.There________(be)somewaterinthebottle.11.Mike_______(like)cooking.12.They_______(have)thesamehobby.13.Myaunt_______(look)afterherbabycarefully.14.Youalways_______(do)yourhomeworkwell.15.I_______(be)ill.I’mstayinginbed.16.She_______(go)toschoolfromMondaytoFriday.17.LiuTao_______(do)notlikePE.18.Thechildoften_______(watch)TVintheevening.19.SuHaiandSuYang_______(have)eightlessonsthisterm.20.－Whatday_______(be)ittoday?It’sSaturday.三、按照要求改写句子1.DanielwatchesTVeveryevening.(改为否定句)___________________________________________________2.Idomyhomeworkeveryday.(改为一般疑问句，作否定回答)____________________________________________________________________________________3.Shelikesmilk.(改为一般疑问句，作肯定回答)___________________________________________________________________________________4.Amylikesplayingcomputergames.(改为一般疑问句，作否定回答)____________________________________________________________________________________________5.Wegotoschooleverymorning.(改为否定句)_______________________________________________________6.HespeaksEnglishverywell.(改为否定句)___________________________________________________7.Iliketakingphotosinthepark.(对划线部分提问)________________________________________________________8.JohncomesfromCanada.(对划线部分提问)___________________________________________________9.Sheisalwaysagoodstudent.(改为一般疑问句，作否定回答)________________________________________________________________________________________10.SimonandDaniellikegoingskating.(改为否定句)___________________________________________________四、改错(划出错误的地方，将正确的写在横线上)1.IsyourbrotherspeakEnglish?__________________2.Doeshelikesgoingfishing?__________________3.Helikesplaygamesafterclass.__________________4.Mr.WuteachsusEnglish.__________________5.Shedon’tdoherhomeworkonSundays.________________七年级英语（上）句型翻译专练3.她叫什么名字?她叫玛里牙.__________________________________________________4.你的号码是多少?是237856____________________________________________________________________5.你的地
