Iamveryhappytoday MikeisanAmericanboy Theyareplayinginthesnow 过去时 HewasinGrade3lastyear Wewereathomeyesterday 将来时 TherewillbeamatchbetweenClass1andClass2tomorrow 3 助动词 不能单独在句中使用 在句中的作用是帮助构成否定 疑问等句式 如 Wedonot don t haveclassesonSaturdays Myfatherdoesnot doesn t workinthehospital Didyougoswimminglastweekend 4 实义动词 小学阶段所学的实义动词有四种形式 即动词原形 第三人称单数形式 现在分词形式 动词的ing形式 和过去式形式 如 1 动词第三人称单数形式的构成 一般情况下 在动词词尾加s 如 work works look looks want wants 以ch sh s x o结尾的动词 在词尾加es 如 teach teaches wash washes dress 装扮 dresses fix 安装 fixes go goes 以辅音字母加y结尾的动词 改y为i 再加es 如 fly flies cry cries 注 play plays buy buys 不规则变化 如 have has be is 2 动词现在分词形式的构成 一般情况下 在动词词尾加ing 如 go going play playing 以不发音的字母e结尾的动词 去e再加ing 如 write writing come coming 以重读闭音节结尾 且词尾只有一个辅音字母的动词 双写最后这个辅音字母再加ing 如 run running swim swimming shop shopping 以ie结尾的动词 将ie改为y 再加ing 如 die dying lie lying 3 动词过去式的构成 一般情况下 在动词词尾加ed 如 work worked play played等 以不发音的字母e结尾的动词 在词尾加d 如 close closed arrive arrived 以辅音字母加y结尾的动词 改y为i 再加ed 如 cry cried study studied 以重读闭音节结尾 且词尾只有一个辅音字母的动词 双写最后这个辅音字母再加ed 如 stop stopped drop dropped 动词的不规则变化 见下表 考点精析 考点1考查动词的变化形式 例1 根据句意和单词首字母提示填写动词 并注意其动词的形式 1 CanyousEnglishsongs 2 Sheusuallygtoschoolat7 00 3 Look AmyiswTV 4 Icmyroomlastnight 解析 本题考查动词基本形式的写法和用法 在做此题时 不仅要考虑主语的人称 还要注意句子的时态 这样才能根据句意和首字母提示填写出动词的正确形式 第1小题应填写动词原形sing 因为情态动词can后要加动词原形 第2小题的主语是第三人称 句子又是陈述习惯性的动作 谓语动词应使用第三人称单数形式goes 第3小题中的look一词提示了本题要用现在进行时 所以要用现在分词watching 第4题由lastnight这一时间状语可知本题要用一般过去时 所以谓语动词应填过去式cleaned 答案 1 sing2 goes3 watching4 cleaned 举一反三用所给单词的适当形式填空 1 Thecat run aroundthetree 2 Theyare clean theirclassroom 3 I have acoldlastweek 4 Don t talk loudlyinthelibrary 5 Mymother make abigcakelastmonth 6 What do shedolastnight 7 Myauntoften go shoppingonSundays 8 Sarah buy aredbagyesterday runs cleaning had talk made did goes bought

第2小题you是非三单形式 用do 第3小题中thismorning表示过去的时间 且过去式不受人称影响 故用did 答案 1 does2 Do3 did 举一反三1 用be动词的适当形式填空 1 I inGradeSixthisyear Lastyear I inGradeFive 2 There manytallbuildingsherenow Twentyyearsago there somesmallhouses 3 MikeandJack twinbrothers Theylookthesame 4 Iwantto ateacherinthefuture 2 用所给单词的适当形式填空 1 will youlikesometea 2 do hewatchTVlastnight am was are were are be Would Did 考点3考查情态动词的使用 例3 单项填空 He readthebooknow A iscanB cansC can解析 本题考查情态动词的正确使用 情态动词can的用法很容易混淆 can和be动词或其他的助动词不能同时出现在句中 can不受人称的影响 故不存在cans的形式 在本题中还要分析清楚 now不表示现在进行时 答案 C 举一反三1 选词填空 1 Iuseyourpen 2 What Idothen 3 You beamiddleschoolstudent 4 We dosomethingforGrandpaLi 5 wegonow Shall May Can should must can 2 按要求完成下列各题 1 IcanspeakChineseandEnglishwell 改成否定句 2 当你想提醒朋友 让他周末要帮助妈妈做家务时 你可以说 3 你想告诉想要闯红灯的人 红灯必须停 你应该说
