Module6语法讲练状语从句的用法外研版（2012）英语九年级上册

Module6状语从句在上一模块中，我们学习了"if从句+祈使句"这一结构。在本模块中，我们继续学习if引导的条件状语从句。我们先来看以下例句：Ifhedoesnotworkhard,hewillfailhisexams.如果他不努力，考试就要不及格了。Ifyoustartnow,you'llfinishitbeforedinner.如果你现在开始（做家庭作业），晚饭前就可以做完了。Ifyoudoalltheseotherthingsinsteadofyourhomework,youwon'thavetimetostudy.如果你在做这些其他的事，不做作业，你就没有时间学习了。从例句中我们可以看出，if引导的从句表示某种假设的情况，主句则表示此种情况所导致的结果。一般来说，这种结构中的从句如果用一般现在时，那么主句的谓语多用一般将来时或"情态动词+动词原形"。我们再来看两个例句：IfIstartafterdinner,I'llfinishitbeforeIgotobed.如果我晚饭后开始（做家庭作业），睡觉前就能做完。Shemayewithusifshearrivesintime.如果她来得及时，就可以和我们一道去。if条件状语从句的时态规则：在主从复合句中，当主句使用一般将来时态时，if引导的条件状语从句应该使用一般现在时态来表示将来。这就是所谓的"主将从现"原则。例如：Ifitrainstomorrow,wewillstayathome.如果明天下雨，我们就待在家里。Ifyoustudyhard,youwillpasstheexam.如果你努力学习，你就会通过考试。情态动词在条件句中的使用：除了will之外，我们还可以在条件句的主句中使用其他情态动词，如can,may,should,must等来表达不同的语气。例如：Ifyoufinishyourwork,youcangohomeearly.如果你完成工作，你可以早点回家。Ifyoufeelsick,youshouldseeadoctor.如果你感觉不舒服，你应该去看医生。if条件句的语序：if条件状语从句可以放在主句之前或之后。当if从句放在句首时，需要用逗号与主句隔开；当if从句放在句末时，通常不需要逗号。例如：Ifyouneedhelp,Iwillbethere.（从句在前）Iwillbethereifyouneedhelp.（从句在后）Module6状语从句习题一、时态填空题：用括号中动词的正确形式填空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、连词选择题：选择正确的连词完成条件状语从句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、句型转换题：按要求转换句子结构1.Studyhardandyouwillpasstheexam.(用if改写)2.Workhard,oryouwon'tsucceed.(用if改写)3.Ifyoudon'thurry,youwillbelate.(用unless改写)4.Ifitdoesn'train,wewillgohiking.(用unless改写)5.Ifyouseehim,pleasegivehimthisbook.(将if从句置于句末)6.Youcanborrowmybikeifyoupromisetoreturnit.(将if从句置于句首)7.Ifyoudon'tpractice,youwon'timprove.(改为肯定句)8.Wewillgotothebeachiftheweatherisgood.(对划线部分提问)9.Ifshehastime,shewillvisitus.(改为一般疑问句)10.Youwillunderstandifyoulistencarefully.(改为否定句)四、句子排序题：将单词重新排列成正确的句子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、改错题：找出下列句子中的错误并改正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、情景写作题：根据情景用if条件句完成句子1.关于学习：IfIstudyhard,______2.关于天气：Ifitrainstomorrow,______3.关于健康：Ifyouwanttokeephealthy,______4.关于时间：IfIhavetimethisweekend,______5.关于交通：Ifwedon'thurry,______6.关于金钱：IfIsaveenoughmoney,______7.关于友谊：Ifyouneedafriend,______8.关于环境：Ifwedon'tprotecttheenvironment,______9.关于梦想：Ifyounevergiveup,______10.关于选择：IfIhavetochoose,______答案部分一、时态填空题1.rains2.study3.gets4.doesn'te5.willfeel6.arrive7.need8.don'tfinish9.willgo10.practices二、连词选择题1B,2A,3C,4A,5A,6C,7B,8C,9A,10A三、句型转换题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、句子排序题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、改错题1.willrain→rains2.willsee→see3.wille→es4.willarrive→arrive5.willneed→
