if条件状语从句的时态练习观察与思考：观察1a中含有if的句子，你发现主句和从句的特点吗？if引导的是一个条件句，主句用__________(时态)，从句用__________(时态)。注意：在与if条件句连用的主句中我们一般用will表示将来时，而不用begoingto表示将来时。(1)if引导的条件句位置灵活，可直接放在主句后面。若if引导的从句在前时，应在句中加__________(标点符号)。(2)如果if条件句谈论的是今后可能出现的情况，则主句大多用_______时；若if条件句谈论的是客观事实，则主句大多用_________时或含情态动词的句子。(3)在if条件句中通常用________时代替一般将来时表将来。一.单项选择（15分）（）1.Ifyou_____totheparty,you’llhaveagreattimeA.willgoB.wentC.goD.going（）2.Itwillbealongtime____Peter_____hiswork.A.since,hasfinishedB.after,finishesC.when,willfinishD.before,finishes.（）3.Whatwillfather_____usfromJapan?A.takeB.bringC.carryD.make（）4.Weifangisfamous______kitesA.forB.toC.onD.with（）5．I____hertheanswerifshe____me.A.cantell,willaskB.willtell,willaskC.wouldtell,askD.willtell,asks（）6.–Whatareyougoingtodotomorrow?--We’llgotothelibrarytomorrowifit___.A.isn’trainB.rainC.won’trainD.doesn’train（）7.—Doyouknowwhenhewillcomebacktomorrow?--Sorry,Idon’tknow.Whenhe____back,I’lltellyou.A.comesB.willcomeC.comeD.maycome（）8.Whatwillyoudoifyou_____totheoldfolk’shomevisit?A.goB.wentC.goingD.willgo（）9.IfIeat____food,I’llbeveryfat.A.toomanyB.manytooC.toomuchD.muchtoo（）10.I’llgivethebooktohimifhe___herenextSunday.A.willcomeB.comesC.iscomingD.came（）11.There____anEnglishfilminourschooltomorrow.A.isgoingtohaveB.willhaveC.isgoingtobeD.has（）12.Couldyoutelluswhere____？A.willthenextOlympicGamesheldB.thenextOlympicGameswillbeheldC.wouldthenextOlympicGamesbeheldD.thenextOlympicGameswouldbeheld（）13.Whenmymotherreturnedlastnight,I____abook.A.readB.amreadingC.wasreadingD.amgoingtoread（）14.What____you____whenitbegantorain?A.do,doB.were,doingC.are,doingD.did,do（）15.I’llwakeyouupwhenhe____back.A.willB.isgoingtocomeC.comesD.come二、用所给词的适当形式填空（每小题3分）1.Ifyou________(feel)tired,you_________(have)tohavearest.2.Where_____he____(see)thefilmifhe_________(have)time?3.Ifthere____(be)fewertrees,there_______(be)morepollution.4.He___(dress)morecasuallyifhe___(notwork)onweekends.5.IfMarcia_______(live)alone,she_______(keep)apetparrot.6.Lana_____buy)anewdressiftheoldone____(be)outofstyle.7.Thetwins_______(fight)ifthey__________(argue).8.I______(have)abakesaleifI____(need)moneyforeducation.9.Peter____(send)meabeautifulsouvenirifhe____(tour)Spain.10.IfMrGreen_______(say)Iamhard-working,myparents___(feel)glad.11.I______(go)tothebeachifit________(notrain)thisweek.12._____they___(have)amatchiftheP.E.teacher__(be)busy?13.He____(write)alettertohisgrandparentsifhe____(get)hisreportcardthisweek.14.Ifshe______(get)uplate,she_____(notcatch)theearlybus.15.Peter____(major)inEnglishifhe____(pass)theexamsinPekingUniversity.三、完成句子(每小题4分)1.如果他到的晚了会发生什么事情？What___________ifhe____late?2.如果努力学习，你就会取得好成绩。Ifyou_________________,you____________good_______.3.他如果看电视太久了，他的父母会不高兴。Ifhe_____TVtoomuch,hisparents______________unhappy.4.如果我们为他组织生日聚会，大家都会来的。Everyone__________ifwe_______abirthdayparty________him.5.如果明天不下雨，我会和你一起去公园的。Ifit___________tomorrow,I_____gotothepark______you.6.如果她睡过头了，就会旅游迟到的。he_____________thetripifshe________7.如果他有空，他会帮助你的。Ifhe________,he__________you.8.如果Tom考试不及格，他就没有机会上高中了。Tom______havethe_____togotothehighschoolifhe________theexams.9.你如果抄同学的作业就不能学好各门功课。You____________goodatallthesubjectsifyou______theotherstudents’homework.10.如果你上课睡觉，老师会生气。Ifyou______inclass,yourteacher_________________you.
