仁爱英语七年级上学期语法一般现在时

一般现在时一般现在时的特征：1.表示事物或人物的特征、状态。如：Theskyisblue.天空是蓝色的。2.表示经常性或习惯性的动作。如：Igetupatsixeveryday.我每天六点起床。3.表示客观现实。如：Theearthgoesaroundthesun.地球绕着太阳转。一、如何判断句子中的主语是单数第三人称？句子中的主语S可以归纳以下三类：S主语（第三人称）单个名字单个人或物He\She\It（如Tina、Paul、Chris等）（如mydaddy\hismommy\yourfriend\thedog\acat\thetalltree等等）二、当句子中的主语S是单数第三人称时，动词单数第三人称形式的变形规律如下：1.大部分的动词+s,如run→runs,swim→swims,hop→hops等2.以ch,sh,o,x,s结尾的动词，必须+es如：wash→washes,teach→teaches,watch→watches,catch→catchesdo→does,go→goes以X,S结尾的动词比较少，只要记住此概念即可。3.以y结尾的动词，有两种情况a.动词以y结尾，并且在y字母旁边含有a,e,i,o,u其中一个字母，动词直接+s如：play→plays(动词中y旁边有a字母)sway→swaysb.动词以y结尾，并且在y字母旁边不含有a,e,i,o,u其中一个字母，动词必须去掉y+ies如：fly→flies,cry→cries,(动词中不含有元音字母)study→studies（动词中含有u,但是不在y的旁边，必须去y+ies）三、如何把陈述句改为一般疑问句？可以按照以下步骤：1.在陈述句中寻找is\am\are\can\will这几个单词Iamagoodstudent.Heisatallboy.Theyarecuteflowers.Icanrunveryfast.Shewillgotothepark.2.若句子中出现以上几个单词，就直接把这几个单词放到句子的最前面，后面句子照抄，注意大小写字母的变化，并把句点改为问号。Iamagoodstudent.→→→→AmIagoodstudent?\Areyouagoodstudent?(Iam是特殊的，通常用Areyou…?进行提问)Heisatallboy.→→→→Isheatallboy?Theyarecuteflowers.→→→→Aretheycuteflowers?Icanrunveryfast.→→→→Canyourunveryfast?(句子中出现I，都要改成you)Shewillgotothepark.→→→→Willshegotothepark?3.若句子中没有出现以上几个单词，就考虑用do\does来进行提问，放在句子的最前面。a.当句子的主语不是单数第三人称时，用do来提问，后面句子照抄，句子中的I变成youIliketoeatapples.→→→→Doyouliketoeatapples?Theyhavefivecats?→→→→Dotheyhavefivecats?句子中主语I\they都不是单数第三人称，所以用do提问，放在句子最前面，有I的地方改成you,其他不变。b.当句子的主语是单数第三人称时，用does来提问，后面句子照抄，但是注意动词必须改为原形。Helikestoeatpizza.→→→→Doesheliketoeatpizza?Thebirdfliesinthesky.→→→→Doesthebirdflyinthesky?Hisdaddyplaysballswithhisfriends.→→→→Doeshisdaddyplayballswithhisfriends?句子中主语He\Thebird\Hisdaddy都是单数第三人称，所以用does提问，放在句子最前面，动词必须改为原形。一、写出下列动词的第三人称单数形式。(讨论第三人称单数形式的变化规则)Model:cleancleans1)watch__________2)have__________3)cook_________4)go__________5)fly_________6)make_________7)swim_________8)draw_________9）ride_________10)play_________二．用动词的正确形式填空。1.Weoften___________(play)intheplayground.2.Heusually_________(get)upatsixo’clock.3.__________you_________(brush)yourteetheverymorning.4.What__________(do)heusually_________(do)afterschool?5.Donnyoften__________(study)Englishatnight.6.Mikesometimes__________(go)totheparkwithhissister.7.Ateightatnight,she__________(watch)TVwithhisparents.8.________Mike________(read)Englisheveryday?9.Sallyoften_______(go)onfoot.10.Myfather_______(read)newspapereverymorning.三．改成疑问句，并作肯定否定回答1.Ioftenplayfootballafterschool.2.Ihavemanybooks.3.GaoShan’ssisterlikesplayingtabletennis4.ShelivesinasmalltownnearNewYork.5.WewatchTVeveryday.6.Davidhasgotacat.7.theygotoschoolbybike.四、选择填空：()1.LiliandSallyoften________basketball.A.playB.playsC.areplaying()2.Doyou______storybooks?A.haveB.hasC.having()3.I______tomusiceverymorning.A.listenB.listeningC.listens()4.What______heusuallydointheafternoon?A.amB.isC.doesD.do()5.Doeshe______TV?A.watchingB.watchC.see()6.She______likeswimming.A.doesn'tB.don'tC.isn't.()7.Theyoften______ballafterschool.A.playsB.playC.playing()8.Canthey______TVA.watchingB.watchC.watches()9.Iwant________homeworknow.A.doingB.todoC.todomy()10．It'stime________.A.gotoschoolB.todomyhomeworksC.togohome()11．________you________theblackboard?Yes,Iam.A.Can,cleanB.Am,cleaningC.Are,cleaning()12．________goandhelpher.A.Let'smeB.Let'susC.Let'sD.Let'sto()13．Dotheyhaveanewcar?Yes,________.A.theydoB.theyhaveC.theydon't()14．Heoften_________supperat6:00intheevening.A.haveB.hasC.ishaving()15.We_____________anyChineseclassesonFridays.A.arehavingB.aren’thavingC.don’thave五、用动词的适当形式填空。1.Tomoften_______(swim)intheriverafterschool.2.Sheusually_______(do)herhomeworkintheevening.3.Mymotheroften______theclothesatnoon.4.Whatdoesyourfather______(do)?He’saworker.5.I_________(be)ill.I’mstayinginbed.6.She_________(go)toschoolfromMondaytoFriday.7.LiuTao_________(do)notlikePE.8.Thechildoften_________(watch)TVintheevening.9.WangKaiandWangli_________(have)eightlessonsthisterm.10.－Whatday_________(be)ittoday?
