小升初英語總第四章 動詞和時態(tài) 第一節(jié) 動詞

第四章第四章 動詞和時態(tài)動詞和時態(tài)第一節(jié)第一節(jié) 動動 詞詞 知識梳理知識梳理一、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： I can play basketball well. Mike can speak Chinese. 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： I am very happy today. Mike is an American boy. They are playing in the snow. 過去時： He was in Grade 3 last year. We were at home yesterday. 將來時： There will be a match between Class 1and Class 2 tomorrow. 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： We do not (dont) have classes on Saturdays. My father does not (doesnt) work in the hospital. Did you go swimming last weekend? 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：workworks，looklooks，wantwants以ch, sh, s, x, o結(jié)尾的動詞，在詞尾加es。如：teachteaches，washwashes，dress(裝扮)dresses，fix(安裝)fixes，gogoes以輔音字母加y結(jié)尾的動詞，改y為i，再加es。如：flyflies，crycries【注】playplays, buybuys不規(guī)則變化。如：havehas，beis (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：gogoing，playplaying以不發(fā)音的字母e結(jié)尾的動詞，去e再加ing。如：writewriting，comecoming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：runrunning，swimswimming，shop shopping以ie結(jié)尾的動詞，將ie改為y，再加ing。如： diedying，lielying (3)動詞過去式的構(gòu)成一般情況下，在動詞詞尾加ed。如：workworked，playplayed等 以不發(fā)音的字母e結(jié)尾的動詞，在詞尾加d。如：closeclosed，arrivearrived 以輔音字母加y結(jié)尾的動詞，改y為i，再加ed。如：crycried，studystudied 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：stopstopped，dropdropped動詞的不規(guī)則變化(見下表)考點精析考點精析考點考點1 考查動詞的變化形式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.Can you s English songs? 2.She usually g to school at 7:00. 3.Look!Amy is w TV. 4.I c my room last night. 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(jìn)行時，所以要用現(xiàn)在分詞watching。第4題由last night 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. sing 2. goes 3. watching 4. cleaned舉一反三 用所給單詞的適當(dāng)形式填空。 1.The cat _ (run) around the tree. 2.They are _(clean) their classroom. 3.I _(have) a cold last week. 4.Dont _ (talk) loudly in the library. 5.My mother _(make) a big cake last month. 6.What _(do) she do last night? 7.My aunt often _ (go) shopping on Sundays. 8.Sarah _(buy) a red bag yesterday.runscleaninghadtalkmadedidgoesbought考點考點2 考查助動詞、考查助動詞、be動詞的使用動詞的使用 【例2】 選擇適當(dāng)?shù)闹鷦釉~填空。1. He not do homework on Friday evening. 2. you have crayons? 3. Tom not read English this morning. 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on Friday evening 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this morning 表示過去的時間，且過去式不受人稱影響，故用did。答案：1. does 2. Do 3. did舉一反三 1. 用be動詞的適當(dāng)形式填空。 (1) I _ in Grade Six this year. Last year， I _ in Grade Five. (2) There _ many tall buildings here now. Twenty years ago， there _ some small houses. (3) Mike and Jack _ twin brothers. They look the same. (4) I want to _ a teacher in the future. 2. 用所給單詞的適當(dāng)形式填空。 (1) _(will) you like some tea？ (2) _ (do) he watch TV last night？ amwasarewerearebeWouldDid考點考點3 考查情態(tài)動詞的使用考查情態(tài)動詞的使用【例3】單項填空。 ( )He _ read the book now. A.is can B.cans C. 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(jìn)行時。 答案：C舉一反三 1. 選詞填空。 (1)_ I use your pen？ (2)What _ I do then？ (3)You _ be a middle school student. (4)We _ do something for Grandpa Li. (5) _ we go now？ ShallMay/Canshouldmustcan 2. 按要求完成下列各題。 (1) I can speak Chinese and English well. (改成否定句) _ (2) 當(dāng)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： _You must stop at a red light.I cant speak Chinese or English well.You should do some housework for your mother on weekends.考點考點4 考查動詞的綜合運用考查動詞的綜合運用【例4】用read的適當(dāng)形式填空。1. You can (read) the book in the library. 2. She (read) a book now. 3. Can I (read) this book now? 4. My father (read) newspapers every morning. 5. Did you （read）the comic book? Yes, I （read）it yesterday. 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(jìn)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every morning 體現(xiàn)一般現(xiàn)在時，而my father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. read 2. is reading 3. read 4. reads 5. read; read舉一反三 1. 用所給動詞的適當(dāng)形式填空。 (1) We _(like) music. Now we _ (sing). (2) Lets _(go) to the cinema. (3) He _(is) ill yesterday.
