1、条件状语从句的主句是一般将来时，那么从句常常用一般现在时。WhenIgrowup,I’llbeanurseandlookafterpatients.我长大后要当一名护士，照顾病人。

2、如果主句是祈使句，那么从句通常要用一般现在时。

Ifyouwanttohaveachat,callmeup.如果你想聊天，打我电话。3、如果主句是含有情态动词时，根据需要从句多用一般现在时。Youshouldbequietwhenyouareinthereadingroom.

在阅览室时应保持安静。四．知识拓展1.在以when，before，assoonas等引导的时间状语从句，也适用“主将从现”原则，即如果主句是一般将来时，从句则用一般现在时。

I'lltellherthegoodnewswhenshecomesback.当她回来的时候，我将把这个好消息告诉她。

shewillgiveyouacallassoonasshereturns.她一回来就会给你电话。2.If条件句的同义句：祈使句，and/or+将来时态的陈述句。Workhard,andyouwillmakegreatprogress.Ifyouworkhard,youwillmakegreatprogress.如果你努力学习，你才会取得大的进步。Hurryup,oryouwillbelate.=Ifyoudon’thurryup.youwillbelate.如果你不快点，你就要迟到了。3.表示普遍真理和客观事实例如：Ifyouheatice,itmeltsIfyouputoilonwater,itfloats.Ifthetemperaturedropsto0degreesCentigrade,waterfreezes.由上述诸例可以看出，凡表示不受时间限制的自然法则的条件句，其if-分句和主句的位于动词都用一般现在时4.表示现在习惯性动作例如：IfImakeapromise,Ikeepit.Ifyougotothemovies,whatkindofmoviedoyouprefertosee?Ifitrains,Igotoworkbycar.在上述表示现在习惯动作的条件句中，if-分句和主句的位于动词也都是用一般现在时5.表示过去习惯性动作例如：Ifitrained,Iwenttoworkbycar.IfImadeapromise,Ikeptit.IfIwashungry,Iusuallyhadafullmeal.在上述表示过去习惯动作的条件句中，if-分句和主句的谓语动词都用一般过去时：【当堂小测】单项选择。（）1.Ifyouwork_________,you_________theexam.A.hard;passB.hardly;willpassC.hard;willpassD.hard;won’t（）2.Workhard,_______youwillfailtheexam.A.andB.orC.butD.because（）3.Ifyou_____totheparty,you’llhaveagreattime.A.willgoB.wentC.goD.going（）4．I____hertheanswerifshe____me.A.cantell,willaskB.willtell,willaskC.wouldtell,askD.willtell,asks（）5–Whatareyougoingtodotomorrow?--We’llgotothelibrarytomorrowifit___.A.isn’trainB.rainC.won’trainD.doesn’train完成句子。1.如果我们为他组织生日聚会，大家都会来的。Everyone___________ifwe__________abirthdaypartyforhim.2.如果明天不下雨，我会和你一起去公园的。Ifit____________tomorrow,I_________gototheparkwithyou.3.如果他有空，他会帮助你的。Ifhe____________,he_____________you.三．用所给动词的适当形式填空。1.Ifsheasksme,I_________(give)hertheanswer.2.I__________(notreturn)thebooktohimifhedoesn’tcomehere.3.What________(youdo)ifitbeginstorain?4.Everyone________(come)ifweholdabirthdaypartyforhim.5.Youwon’tseethebiggestmooncakeifyou________(notcome)tomyshop答案：一.1-5CBCDD二．willcome;hold2.doesn’train;will3.isfree;willhelp三．1.willgive2.won’treturn3.willyoudo4.willcome5.don’tcome【课后作业】语法填空。TheDailyMirrorsaysthatspringcomesearly,1.___________theBBCsaysitcomeslate.2.__________isright?Theanswerisabitofboth.Weallhave3.___________ideaofwhatspring4._________(mean)manyflowers,5._______(warm)weather,morerain,birds’singingandsoon.6.__________youthinkwhenthethrushes(画眉鸟)sing,springcomes,thenit’slatethisyear.Ifyouthinkwhenflowerscomeout,springcomes,thenit’searly.Bluebells(风铃草)？Springcanberight7._______time.There8._________(be)manythingsinSpring,buttheydon’tallcomeatthesametime.Somemaycomeearly,andsomemaycomelate.Sowedon’tdefine(定义)springby9.______(look)atoneanimalorplant.Wemustwatchmany10._______(thing)todefineit.Doyouthinkso?二．阅读理解阅读下列短文，从每小题的三个选项中选出最佳选项．ItwasthelastMathsexambeforesummer,butScottdidn'tworry．HewasthebestMathsstudentandheneverhadtoworkveryhardatit．Asusual,hefinishedtheexamveryquickly．Thenextday，Scottwascalledtotheheadmaster'soffice．Whenhearrived，theMathsteacherandtheheadmasterwerethere．"Wow!"hethought．"Imusthavescored100intheexam!"Sureenough，theheadmastersaidthemeetingwasabouthisMathsexam．However，whathesaidnextleftScottshocked（震惊）．"Youfailed，"theheadmastersaid．"Sinceyouweresmall，you'vefoundMathseasy．It'stimeyoulearnedthatyoucouldn'tjusttakeanexamunprepared．IwaslikeyouwhenIwasachild．Iwasgoodatscience，butoneday，Ifailedabigexam．Youseethispicture？Itwasgiventomebymyscienceteacherthatday．Thisbirdiscalledabuzzard（鹫）．Readwhatitsaysatthebottom．"Scottreaditaloud，"WelcometotheBuzzardClub．Remember，it'snotabouttalents．It'sabouthardwork．""Abuzzardcanonlyflyifitgetsarunningstart，"theheadmastersays．"Itcan'tjustleap（跃）intotheairlikeotherbirds．Butonceit'sintheair，itcanflytogreatheights．Remember，studyingislikethatrunningstart．Withyourtalentyouwillflyhigh!"1．What
