条件状语从句练习

if引导的条件状语从句if引导的条件状语从句的用法,现在总结一下:if条件句不一般,几个要点记心间;条件句,放在前,逗号要放句中间。条件句表可能，主句多用将来时；条件句表事实，主句常用现在时。在if引导的条件状语从句中，如果从句谈论的是一个有可能发生的事实及其产生的相关的结果，主句用一般将来时态，从句用一般现在时态。如：Wecanwalkthereifwecan'tfindabus.Ifitrainstomorrow，wewillnotgotothezoo.Whatwillyoudoifyoufindapandaindanger.如果if条件句谈论的是重复发生和预示要发生的情景和事件，则主从句大多用一般现在时态。如：Ifbearsareindanger，theyattackpeople.注意：在if引导的条件状语从句中，if和条件句位置灵活，可直接放在主句后面，若if条件句放句首，从句后面要加逗号，和主句隔开。一单项选择(d)1.We___betterifweeatlessfood.A.aren’tfeelB.don’tfeelC.didn’tfeelD.won’tfeel(c)2.Iwon’tgoifit___tomorrow.A.rainB.israiningC.rainsD.willrain(c)3．Idon’tknowifhe_______.Ifhe_______,pleaseletmeknow.A.comes,comesB.willcome,willcomeC.willcome,comesD.comes,willcome(a)4.Yourteacherwillbeunhappyifyou_______toschoollate.A.comeB.willcomeC.arecomingD.came(c)5.We’llgotothefarmandhelpthefarmerswiththeapple-pickingifit____tomorrow.A.won’trainB.willberainyC.doesn’trainD.isn’training(c)6.Thereisgoingto_______asportsmeetingnextweek.Ifit________,we’llhavetocancelit.A.be,willrainB.have,willrainC.be,rains(c)7.Wehaven’tdecidedif_________.A.willwetakeafieldtripB.wetakeafieldtripC.we’lltakeafieldtrip(a)8.Readitaloud_____theclasscanhearyou.A.sothatB.ifC.whenD.although(c)9．Ifit________,I'llgotothezoo.A.won'trainB.don'trainC.doesn'trainD.rain(c)10.Ifit______sunnytomorrow,I____boating.A.is,goB.willbe,goC.is,willgoD.willbe,willgo(b)11.----whatwillyoudoifit______tomorrow,----I’llstayathomeandwatchTV.A.rainB.rainsC.willrainD.israining(c)12．Ifhe______hardernexttime,hewillcatchupwithus.A.workB.workedC.worksD.willwork二同义句转换1.Runfast,oryou’llbelateforschool._______you______________fast,you’llbelateforschool.2.Youcanbuythedictionaryifyoutakeenoughmoneywithyou.Takeenoughmoneywithyou,_________________buythedictionary.3.Ifthereisnoair,noneofuscanlive.Noneofuscanlive________________.三连词成句1.jeans,in,teacher,you,if,let,wear,the,won’t,you_________________________________________________________________2.sorry,stays,she,if,she,feel,at,will,home_________________________________________________________________3.some,to,I,school,rules,of,for,you,parties,want,remind_________________________________________________________________4.ID,what,to,if,I,card,forget,bring,happen,my,will_________________________________________________________________5.I,if,I,don’t,it,it,now,do,do,never,will_________________________________________________________________四请将下列句子翻译成英语。1.如果明天有空，我和你一起参观十三陵。_______________________________________________2.如果我们骑自行车去上班，我们可以避免空气污染。______________________________________________3.如果你去青海湖，你将能看到青海湖自行车比赛。_______________________________________________4.如果明天他不来,我会代替他去的。_______________________________________________3.如果明天不下雨，我们将会参观天安门广场_______________________________________________4.如果天下雨，我们就不去长城__________________________________________________5.如果他们误了车，将会发生什么？____________________________________________________6.如果我们今天开party，将有一半的同学不能来______________________________________________________7.如果我们看录像，我会感到乏味____________________________________________________-8.如果我上大学，我将永远不会成为一名伟大的足球运动员_____________________________________________________五．完型填空Someonesays,“Timeismoney”,butIthinktimeis1importantthanmoney.Why?Becausewhenmoneyisspent,wecangetitback.However,whentimeis2,it’llnever3.Thatis4wemustnotwastetime.Itgoeswithoutsayingthatthe5isusuallylimited.Everasecondisveryimportant.Weshouldmakefulluseofourtimeto6useful.Butitisapitythattherearealotofpeoplewhodonotknowtheimportanceofthetime.Theyspenttheirlimitedtimesmoking,drinkingand7.Theydonotknowthatwastingtimemeanswastingpartoftheirown8.Inaword,weshouldsavetime.Weshouldn’t9today’sworkfortomorrow.Rememberwehavenotimeto10.()1.A.muchB.lessC.mushlessD.evenmore()2.A.costB.boughtC.goneD.finished()3.A.returnB.carryC.takeD.bring()4.A.whatB.thatC.becauseD.why()5.A.moneyB.timeC.dayD.food()6.A.nothingB.somethingC.anythingD.everything()7.A.readingB.writingC.playingD.working()8.A.timeB.foodC.moneyD.life()9.A.stopB.leaveC.letD.give()10.A.loseB.saveC.spendD.take六.阅读理解：Dreamsmaybemoreimportantthansleep.Somepeopledon’tneedmuchsleep.Butweallneedtodream,scientistssay.Dreamstakeupaboutonequarterofoursleepingtime.Peoplehaveseveraldreamseachnight.Dreamsarelikeshortfilms.Theyareusuallyincolor.Somedreamsarelikeoldfilms.Theycometousoverandoveragain.Thatmaybebecausethedreamerisworryingaboutsomething.Dreamingmaybeawayoftryingtofindananswer.Somepeoplegetnewideasabouttheirworkfromdreams.Theycouldhavebeenthinkingabouttheirworkallday.Thesethoughtscancarryoverintodreams.Sometimeswewakeupwithagoodfeelingfromadream.Butoftenwecan’trememberthedream.Dreamscandisappearquicklyfrommemory.Toomuchdreamingcanbeharmful.Themorewesleep,thelongerwedream.Themindishardatworkingwhenwedream.Thatiswhywemayhavealongsleepandstillwakeuptired.1.Itmaybelessimportanttosleepthanto_______.A.thinkB.dreamC.workD.study2.Dreamsandfilmsareusually______.A.verylongB.incolorC.aboutworkD.verysad3.Thepeopleoftendreamabouttheirworkbecause_______.A.theyaretiredinthedaytimeB.theyarenotinterestedintheirworkC.theymaybethinkingabouttheirworkatallD.theyhavetoomuchwor
