Module6狀語從句在上一模塊中，我們學(xué)習(xí)了"if從句+祈使句"這一結(jié)構(gòu)。在本模塊中，我們繼續(xù)學(xué)習(xí)if引導(dǎo)的條件狀語從句。我們先來看以下例句：Ifhedoesnotworkhard,hewillfailhisexams.如果他不努力，考試就要不及格了。Ifyoustartnow,you'llfinishitbeforedinner.如果你現(xiàn)在開始（做家庭作業(yè)），晚飯前就可以做完了。Ifyoudoalltheseotherthingsinsteadofyourhomework,youwon'thavetimetostudy.如果你在做這些其他的事，不做作業(yè)，你就沒有時間學(xué)習(xí)了。從例句中我們可以看出，if引導(dǎo)的從句表示某種假設(shè)的情況，主句則表示此種情況所導(dǎo)致的結(jié)果。一般來說，這種結(jié)構(gòu)中的從句如果用一般現(xiàn)在時，那么主句的謂語多用一般將來時或"情態(tài)動詞+動詞原形"。我們再來看兩個例句：IfIstartafterdinner,I'llfinishitbeforeIgotobed.如果我晚飯后開始（做家庭作業(yè)），睡覺前就能做完。Shemayewithusifshearrivesintime.如果她來得及時，就可以和我們一道去。if條件狀語從句的時態(tài)規(guī)則：在主從復(fù)合句中，當(dāng)主句使用一般將來時態(tài)時，if引導(dǎo)的條件狀語從句應(yīng)該使用一般現(xiàn)在時態(tài)來表示將來。這就是所謂的"主將從現(xiàn)"原則。例如：Ifitrainstomorrow,wewillstayathome.如果明天下雨，我們就待在家里。Ifyoustudyhard,youwillpasstheexam.如果你努力學(xué)習(xí)，你就會通過考試。情態(tài)動詞在條件句中的使用：除了will之外，我們還可以在條件句的主句中使用其他情態(tài)動詞，如can,may,should,must等來表達不同的語氣。例如：Ifyoufinishyourwork,youcangohomeearly.如果你完成工作，你可以早點回家。Ifyoufeelsick,youshouldseeadoctor.如果你感覺不舒服，你應(yīng)該去看醫(yī)生。if條件句的語序：if條件狀語從句可以放在主句之前或之后。當(dāng)if從句放在句首時，需要用逗號與主句隔開；當(dāng)if從句放在句末時，通常不需要逗號。例如：Ifyouneedhelp,Iwillbethere.（從句在前）Iwillbethereifyouneedhelp.（從句在后）Module6狀語從句習(xí)題一、時態(tài)填空題：用括號中動詞的正確形式填空1.Ifit______(rain)tomorrow,wewillcancelthepicnic.2.Ifyou______(study)hard,youwillpasstheexam.3.Shewillbehappyifshe______(get)thejob.4.Ifhe______(note)soon,wewillstartwithouthim.5.You______(feel)betterifyoutakethismedicine.6.Ifthey______(arrive)early,theycangetgoodseats.7.IwillcallyouifI______(need)anyhelp.8.Ifyou______(notfinish)yourhomework,youcannotwatchTV.9.We______(go)swimmingiftheweatherisnice.10.Ifhe______(practice)everyday,hewillimprovequickly.二、連詞選擇題：選擇正確的連詞完成條件狀語從句1.______youdon'thurry,youwillbelateforschool.A.UnlessB.IfC.WhenD.Because2.______itdoesn'train,wewillhaveapicnicinthepark.A.IfB.BecauseC.AlthoughD.So3.Youwillfailthetest______youdon'tstudyforit.A.becauseB.soC.ifD.when4.______youneedmyhelp,justgivemeacall.A.IfB.BecauseC.AlthoughD.Sothat5.Wecanplayoutside______theweatherisgood.A.ifB.becauseC.althoughD.so6.______youdon'tunderstandthelesson,asktheteacherforhelp.A.BecauseB.SoC.IfD.Although7.Youwon'tsucceed______youworkhard.A.ifB.unlessC.becauseD.when8.______youfinishyourworkearly,youcangohome.A.BecauseB.SoC.IfD.Although9.______youseeJohn,tellhimI'mlookingforhim.A.IfB.BecauseC.AlthoughD.Sothat10.We'llmissthetrain______wedon'tleavenow.A.ifB.becauseC.althoughD.sothat三、句型轉(zhuǎn)換題：按要求轉(zhuǎn)換句子結(jié)構(gòu)1.Studyhardandyouwillpasstheexam.(用if改寫)2.Workhard,oryouwon'tsucceed.(用if改寫)3.Ifyoudon'thurry,youwillbelate.(用unless改寫)4.Ifitdoesn'train,wewillgohiking.(用unless改寫)5.Ifyouseehim,pleasegivehimthisbook.(將if從句置于句末)6.Youcanborrowmybikeifyoupromisetoreturnit.(將if從句置于句首)7.Ifyoudon'tpractice,youwon'timprove.(改為肯定句)8.Wewillgotothebeachiftheweatherisgood.(對劃線部分提問)9.Ifshehastime,shewillvisitus.(改為一般疑問句)10.Youwillunderstandifyoulistencarefully.(改為否定句)四、句子排序題：將單詞重新排列成正確的句子1.will/if/rain/we/it/stay/home/at2.hard/you/succeed/work/if/you/will3.early/finish/if/can/leave/you/you4.hungry/eat/if/something/you/are5.time/have/if/we/will/we/fun/a6.careful/be/if/want/you/don't/to/hurt/yourself7.help/need/if/ask/you/me8.late/don't/if/be/hurry/you/you/will9.better/feel/medicine/if/take/you/the/will/you10.tickets/get/if/we/can/we/early/start五、改錯題：找出下列句子中的錯誤并改正1.Ifitwillrain,wewillstayathome.2.Ifyouwillseehim,tellhimI'mwaiting.3.Ifshewille,wecanstartthemeeting.4.Iftheywillarriveearly,wecanhavelunchtogether.5.Ifyouwillneedhelp,justcallme.6.Ifhewillstudyhard,hewillpasstheexam.7.Ifwewillhavetime,wewillvisitthemuseum.8.Ifyouwillfinishyourwork,youcangohome.9.Ifshewillbelate,wewillstartwithouther.10.Iftheywillwinthegame,theywillbeveryhappy.六、情景寫作題：根據(jù)情景用if條件句完成句子1.關(guān)于學(xué)習(xí)：IfIstudyhard,______2.關(guān)于天氣：Ifitrainstomorrow,______3.關(guān)于健康：Ifyouwanttokeephealthy,______4.關(guān)于時間：IfIhavetimethisweekend,______5.關(guān)于交通：Ifwedon'thurry,______6.關(guān)于金錢：IfIsaveenoughmoney,______7.關(guān)于友誼：Ifyouneedafriend,______8.關(guān)于環(huán)境：Ifwedon'tprotecttheenvironment,______9.關(guān)于夢想：Ifyounevergiveup,______10.關(guān)于選擇：IfIhavetochoose,______答案部分一、時態(tài)填空題1.rains2.study3.gets4.doesn'te5.willfeel6.arrive7.need8.don'tfinish9.willgo10.practices二、連詞選擇題1B,2A,3C,4A,5A,6C,7B,8C,9A,10A三、句型轉(zhuǎn)換題1.Ifyoustudyhard,youwillpasstheexam.2.Ifyoudon'tworkhard,youwon'tsucceed.3.Unlessyouhurry,youwillbelate.4.Unlessitrains,wewillgohiking.5.Pleasegivehimthisbookifyouseehim.6.Ifyoupromisetoreturnit,youcanborrowmybike.7.Ifyoupractice,youwillimprove.8.Whatwillyoudoiftheweatherisgood?9.Willshevisitusifshehastime?10.Youwon'tunderstandifyoudon'tlistencarefully.四、句子排序題1.Ifitrains,wewillstayathome.2.Ifyouworkhard,youwillsucceed.3.Ifyoufinishearly,youcanleave.4.Ifyouarehungry,eatsomething.5.Ifwehavetime,wewillhavefun.6.Ifyoudon'twanttohurtyourself,becareful.7.Ifyouneedhelp,askme.8.Ifyoudon'thurry,youwillbelate.9.Ifyoutakethemedicine,youwillfeelbetter.10.Ifwestartearly,wecangettickets.五、改錯題1.willrain→rain
