校教研課教案Infinitives動詞不定式Class:10級計算機1班TeachingTime:第九周星期四下午第1節(jié)Teacher:HeWen教學目標：1.掌握動詞不定式的幾種形式2.掌握動詞不定式在句子中可以作什么成分3.掌握動詞不定式用法/功能4.掌握運用動詞不定式注意事項教學難點：動詞不定式用法教學方法：通過放映幻燈片，教師講解，學生思考，最后總結的方法來實現(xiàn)本課的教學任務。教學過程：Step1.出示幻燈片讓學生了解動詞不定式的幾種形式1.動詞不定式的基本形式to+動詞原形有時可以不帶to(禿頭不定式）2.動詞不定式的否定形式not/never+todonot/never+do3.不定式的邏輯主語It’sgoodforyoutodomorningexercises.Thequestionistoodifficultforustoanswer.It’stoodarkformetoseeanythingintheroom.It’sverykindofyoutothinkoftheothers.如果要說明不定式表示的動作是誰做的，可以在不定式前加一個for(of)引起的短語。介詞for(of)的賓語叫不定式的邏輯主語。Step2.請學生思考：動詞不定式在句子中可以作什成分？學生得出結論：1.作主語2.作賓語3.作賓語補足語4.作定語5.作狀語5.作狀語6.作表語7.與疑問詞等連用Step3.出示幻燈片讓學生根據總結結果加強記憶。Step4.討論動詞不定式用法/功能，并總結：(1).作主語Toseeistobelieve.It’sexcitingtosurfontheInternet作主語的不定式如果很短，通常位于句首；若不定式（短語）較長時，常用it作形式主語，而把真正的主語（即動詞不定式）放在后面以避免頭重腳輕。(2)賓語Iwanttogohome.Theworkersdecidedtogetbetterpay.Ifounditnecessarytotalktohimagain.常用動詞不定式作賓語的動詞有：want,hope,wish,refuse,learn,wouldlike,choose,decide,agree,pretend,expect,plan…Hefounditverydifficulttogettosleep不定式作賓語時，如帶有賓語補足語，則要把不定式放到后面，用it作形式賓語，構成“主語+動詞+it+賓補（形容詞、名詞）+不定式”結構。感官動詞和使役動詞等后接不定式作賓補時，需省to。但在被動語態(tài)中要還帽子。Thebossmakesthemwork15hoursaday.Isawtheaccidenthappenyesterday.Hewasmadetodohiswork(byme).(3).賓補Theteachertoldmetocleantheblackboard.Iexpectyoutogivemesomehelp.Heoftenhelpsme(to)repairmybike.常用動詞不定式作賓補的動詞有：tell,ask,want,warn,wish,allow,encourage,expect,teach,help(4).定語Ihavesomethingtosay.Hehasalotofhomeworktodo.Heislookingforaroomtolivein.Thereisnothingtoworryabout.動詞不定式若在句中作定語，常放在被修飾的名詞或代詞后。如果不定式中的動詞是不及物動詞,則要帶上與之搭配的介詞，構成及物動詞短語。(5)狀語Hegotupearlytocatchthetrain.Let’sstoptohavearest.I’mveryhappytoseeyou.He’stooyoungtogotoschool.Sheisoldenoughtodressherself動詞不定式作狀語主要用來表示目的，原因，或結果等。(6).表語Myjobistohelpthepatient.Yourtaskistocleantheclassroom.不定式可以放在be動詞后，形成表語。(7)與疑問詞連用Hedidn’tknowwhattosay.(賓語)Howtosolvetheproblemisveryimportant.(主語)Myquestioniswhentostart.(表語)不定式與疑問詞who,which,when,how,what等連用，形成帶疑問詞的不定式。在句中起名詞作用，可充當主語、表語、賓語等。在與why連用時，只用于why或whynot開頭的簡短疑問句中，后面緊跟的動詞不定式不帶to。Whydosth.?Whynotdosth.?Step5出示幻燈片讓學生注意幾個易錯點。1.有些動詞既可跟不定式作賓語，也可跟動名詞作賓語，但含義不同：remembertodo記住要做某事；rememberdoing記得曾經做過某事forgettodo忘記要做某事forgetdoing忘記曾經做過某事stoptodo停下來去做某事stopdoing停止做某事goontodo繼續(xù)做另一件事goondoing繼續(xù)做原來在做的事Irememberseeingyousomewherebefore.我記得以前在哪兒見過你。Pleaseremembertoturnoffthelightwhenyouleave.離開時請記得關好燈。Iforgottotellheraboutit.我忘記告訴她這件事。Iforgottellingheraboutit.我忘記了曾把這件事告訴過她。2.感官動詞后既可跟不帶to的不定式作賓補，也可跟v-ing作賓補，前者表示動作的全部過程已結束；后者表示動作正在進行。Isawhimcomedownstairs.我看見他下了樓。（說明他下樓了這件事）Isawhimcomingdownstairs.我看見他在下樓。（說明他下樓時的情景）Iheardsomeonecallingme.Iheardmynamecalled.Step6.通過練習來加強學生對本課知識的掌握。Fillineachblankwiththeproperwordfromthebrackets:1.Mikewants________(go)toaparkonSunday.2.Theteacheroftentellsus___________(notbe)late.3.Mybrotheristooyoung________(join)thearmy.4.Ittakesmeanhour_____(do)myhomeworkeveryday.5.Doyouhaveanything_________(say)?6.Hisparentsoftenmakehim_______(do)alotofexercises.7.Hetooklessons_________(learn)how_________(sing).8.Mothertoldhim___________(notplay)footballinthestreet.9.I’mveryglad____________(pass)theexam.10.Yourskirtisnice.Letme_________(have)alook.11.Thestudentsweremade___________(copy)thetextthreetimes.12.You’dbetter________(notgo)therebecauseitisdark.13.Ihavealotofhomework_________(do)everyday.14.Thelittleboylikes_____________________(answer)questions.15.Wouldyoulike__________(join)us?16.Mr.Wangtaughtme___________(play)basketball.17.Mywatchneeds_______________________(repair).18.Ifinditimportant________(learn)Englishwell.19.Itisdifficult______________(answer)thisquestion.20.YesterdayIsawtheaccident_________(happen).21.Theimportantthingis__________(save)lives.22.Ioftenhelpmymother____________(do)housework.23.WeoftenhearMary___________(sing)inherroom.24.Wearetired.Let’sstop____________(have)arest.25.It’sverykindofyou__________(think)somuchofus.26.It’seasyforme____________(repair)thebike.27.Thereisnothing___________(worry)about.28.Iamrichenough____________(buy)acar.29.Whynot__________(go)withme?30.Don’tforget_________(close)thedoorwhenyouleave.Correctthemistakes:Themanwastiredenoughtostophavingarest.Whatwordscanyouusedescribethebeautifulscene?Theteachertoldustonotmakesomuchnoise.Theyareoftenseenplayontheplayground
