2019小升初英語總復(fù)習(xí) 第四章 動詞和時態(tài) 第一節(jié) 動詞課件.ppt

第四章動詞和時態(tài) 第一節(jié)動詞 知識梳理 一 動詞的概念與分類動詞是句子中表示動作或者狀態(tài)的詞 根據(jù)動詞的詞義和在句中的作用 可以將動詞劃分為如下幾類 二 動詞的基本形式1 情態(tài)動詞 沒有人稱和數(shù)的變化 后面接動詞原形 如 Icanplaybasketballwell MikecanspeakChinese 2 be動詞 根據(jù)人稱和時態(tài)的不同 呈現(xiàn)不同形式 如 現(xiàn)在時 Iamveryhappytoday MikeisanAmericanboy Theyareplayinginthesnow 過去時 HewasinGrade3lastyear Wewereathomeyesterday 將來時 TherewillbeamatchbetweenClass1andClass2tomorrow 3 助動詞 不能單獨在句中使用 在句中的作用是幫助構(gòu)成否定 疑問等句式 如 Wedonot don t haveclassesonSaturdays Myfatherdoesnot doesn t workinthehospital Didyougoswimminglastweekend 4 實義動詞 小學(xué)階段所學(xué)的實義動詞有四種形式 即動詞原形 第三人稱單數(shù)形式 現(xiàn)在分詞形式 動詞的ing形式 和過去式形式 如 1 動詞第三人稱單數(shù)形式的構(gòu)成 一般情況下 在動詞詞尾加s 如 work works look looks want wants 以ch sh s x o結(jié)尾的動詞 在詞尾加es 如 teach teaches wash washes dress 裝扮 dresses fix 安裝 fixes go goes 以輔音字母加y結(jié)尾的動詞 改y為i 再加es 如 fly flies cry cries 注 play plays buy buys 不規(guī)則變化 如 have has be is 2 動詞現(xiàn)在分詞形式的構(gòu)成 一般情況下 在動詞詞尾加ing 如 go going play playing 以不發(fā)音的字母e結(jié)尾的動詞 去e再加ing 如 write writing come coming 以重讀閉音節(jié)結(jié)尾 且詞尾只有一個輔音字母的動詞 雙寫最后這個輔音字母再加ing 如 run running swim swimming shop shopping 以ie結(jié)尾的動詞 將ie改為y 再加ing 如 die dying lie lying 3 動詞過去式的構(gòu)成 一般情況下 在動詞詞尾加ed 如 work worked play played等 以不發(fā)音的字母e結(jié)尾的動詞 在詞尾加d 如 close closed arrive arrived 以輔音字母加y結(jié)尾的動詞 改y為i 再加ed 如 cry cried study studied 以重讀閉音節(jié)結(jié)尾 且詞尾只有一個輔音字母的動詞 雙寫最后這個輔音字母再加ed 如 stop stopped drop dropped 動詞的不規(guī)則變化 見下表 考點精析 考點1考查動詞的變化形式 例1 根據(jù)句意和單詞首字母提示填寫動詞 并注意其動詞的形式 1 CanyousEnglishsongs 2 Sheusuallygtoschoolat7 00 3 Look AmyiswTV 4 Icmyroomlastnight 解析 本題考查動詞基本形式的寫法和用法 在做此題時 不僅要考慮主語的人稱 還要注意句子的時態(tài) 這樣才能根據(jù)句意和首字母提示填寫出動詞的正確形式 第1小題應(yīng)填寫動詞原形sing 因為情態(tài)動詞can后要加動詞原形 第2小題的主語是第三人稱 句子又是陳述習(xí)慣性的動作 謂語動詞應(yīng)使用第三人稱單數(shù)形式goes 第3小題中的look一詞提示了本題要用現(xiàn)在進行時 所以要用現(xiàn)在分詞watching 第4題由lastnight這一時間狀語可知本題要用一般過去時 所以謂語動詞應(yīng)填過去式cleaned 答案 1 sing2 goes3 watching4 cleaned 舉一反三用所給單詞的適當形式填空 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 考點2考查助動詞 be動詞的使用 例2 選擇適當?shù)闹鷦釉~填空 1 HenotdohomeworkonFridayevening 2 youhavecrayons 3 TomnotreadEnglishthismorning 解析 本題考查學(xué)生對助動詞do的三種形式的正確運用 第1小題中onFridayevening是常態(tài) 用一般現(xiàn)在時 而主語he是三單形式 所以用一般現(xiàn)在時的三單形式does 第2小題you是非三單形式 用do 第3小題中thismorning表示過去的時間 且過去式不受人稱影響 故用did 答案 1 does2 Do3 did 舉一反三1 用be動詞的適當形式填空 1 I inGradeSixthisyear Lastyear I inGradeFive 2 There manytallbuildingsherenow Twentyyearsago there somesmallhouses 3 MikeandJack twinbrothers Theylookthesame 4 Iwantto ateacherinthefuture 2 用所給單詞的適當形式填空 1 will youlikesometea 2 do hewatchTVlastnight am was are were are be Would Did 考點3考查情態(tài)動詞的使用 例3 單項填空 He readthebooknow A iscanB cansC can解析 本題考查情態(tài)動詞的正確使用 情態(tài)動詞can的用法很容易混淆 can和be動詞或其他的助動詞不能同時出現(xiàn)在句中 can不受人稱的影響 故不存在cans的形式 在本題中還要分析清楚 now不表示現(xiàn)在進行時 答案 C 舉一反三1 選詞填空 1 Iuseyourpen 2 What Idothen 3 You beamiddleschoolstudent 4 We dosomethingforGrandpaLi 5 wegonow Shall May Can should must can 2 按要求完成下列各題 1 IcanspeakChineseandEnglishwell 改成否定句 2 當你想提醒朋友 讓他周末要幫助媽媽做家務(wù)時 你可以說 3 你想告訴想要闖紅燈的人 紅燈必須停 你應(yīng)該說

thisbooknow 4 Myfather read newspaperseverymorning 5 Didyou read thecomicbook Yes I read ityesterday 解析 本題圍繞一個詞read展開 考查了不同時態(tài) 不同人稱情況下 實義動詞的用法 第1小題中can 原形動詞 第2小題now表示的是現(xiàn)在 體現(xiàn)現(xiàn)在進行時 she是三單形式 故而be 動詞的ing形式是本小題需要的答案 第3小題不管后面出現(xiàn)什么 can 原形動詞 第4小題everymorning體現(xiàn)一般現(xiàn)在時 而myfather是第三人稱 故而動詞要用三單形式 第5小題did之后加動詞原形 答句中用過去式形式 read的過去式和原形同形 答案 1 read2 isreading3 read4 reads5 read read 舉一反三1 用所給動詞的適當形式填空 1 We like music Nowwe sing 2 Let s go tothecinema 3 He is illyesterday 4 Canyou clean thetablenow 5 Doyou go totheparkonSaturdays like aresinging go was clean go 2 單項填空 1
