完整版初中條件狀語從句精講和練習(xí)含答案初中英語：條件狀語從句一．條件狀語從句的概念等if或unless條件狀語從句，即在某種條件下，一件事情可能發(fā)生。在英語中由連接詞引導(dǎo)的狀語從句叫做條件狀語從句。條件是指某一件事情實現(xiàn)之后（狀語從句中），一件事等意思。條件狀語從句中，主從句的時“假如，只要，如果”情（主句）才能發(fā)生，通常譯作主將從現(xiàn)”的原則。即，主句是將來時態(tài)時，從句用一般現(xiàn)在時代替將來時態(tài)。態(tài)要遵循“二.條件狀語從句的引導(dǎo)詞conj.如果，假如1.If如果你請他幫忙，他會幫你的。Ifyouaskhim，hewillhelpyou．如果你考試不及格，你會讓他失望的。，youwilllethimdown．Ifyoufailintheexamif...not...）的時候除非在……（2.unlessconj.除非,若不,你就不能及時趕到那兒。Youwillfailtoarrivethereintimeunlessyoustartearlier.如果你不早點動身,,比賽將照常進行。Unlessitrains,thegamewillbeplayed.除非下雨3.so/aslongasconj.只要Youmayborrowmybookaslongasyoukeepitclean.只要你保持書的清潔，你就可以把我的書借去。三．關(guān)于條件句的時態(tài)，常見的有以下三種情況：1、條件狀語從句的主句是一般將來時，那么從句常常用一般現(xiàn)在時。WhenIgrowup,I'llbeanurseandlookafterpatients.我長大后要當(dāng)一名護士，照顧病人。2、如果主句是祈使句，那么從句通常要用一般現(xiàn)在時。Ifyouwanttohaveachat,callmeup.如果你想聊天，打我電話。3、如果主句是含有情態(tài)動詞時，根據(jù)需要從句多用一般現(xiàn)在時。Youshouldbequietwhenyouareinthereadingroom.在閱覽室時應(yīng)保持安靜。四．知識拓展1在以when，before，assoonas等引導(dǎo)的時間狀語從句，也適用“主將從現(xiàn)”原則，即如果主句是一般將來時，從句則用一般現(xiàn)在時。I'lltellherthegoodnewswhenshecomesback.當(dāng)她回來的時候，我將把這個好消息告訴她。shewillgiveyouacallassoonasshereturns.她一回來就會給你電話。2.If條件句的同義句：祈使句，and/or+將來時態(tài)的陳述句。Workhard,andyouwillmakegreatprogress.=Ifyouworkhard,youwillmakegreatprogress.如果你努力學(xué)習(xí)，你才會取得大的進步。Hurryup,oryouwillbelate.=Ifyoudon'thurryup.youwillbelate.如果你不快點，你就要遲到了。1條件狀語從句練習(xí)精講（含答案）Ⅰ.單項選擇1.Ifyou_____totheparty,you'llhaveagreattime.A.willgoB.wentC.goD.going2.Itwillbealongtime____Peter_____hiswork.A.since,hasfinishedB.after,finishesC.when,willfinishD.before,finishes.3.Whatwillfather_____usfromJapan?A.takeB.bringC.carryD.make4.Weifangisfamous______kitesA.forB.toC.onD.with5．I____hertheanswerifshe____me.A.cantell,willaskB.willtell,willaskC.wouldtell,askD.willtell,asks6.–Whatareyougoingtodotomorrow?--We'llgotothelibrarytomorrowifit___.A.isn'trainB.rainC.won'trainD.doesn'train7.—Doyouknowwhenhewillcomebacktomorrow?--Sorry,Idon'tknow.Whenhe____back,I'lltellyou.A.comesB.willcomeC.comeD.maycome8.Whatwillyoudoifyou_____totheoldfolk'shomevisit?A.goB.wentC.goingD.willgo9.IfIeat____food,I'llbeveryfat.A.toomanyB.manytooC.toomuchD.muchtoo10.I'llgivethebooktohimifhe___herenextSunday.A.willcomeB.comesC.iscomingD.came11.There____anEnglishfilminourschooltomorrow.A.isgoingtohaveB.willhaveC.isgoingtobeD.has12.Couldyoutelluswhere____？A.willthenextOlympicGamesheldB.thenextOlympicGameswillbeheldC.wouldthenextOlympicGamesbeheldD.thenextOlympicGameswouldbeheld13.Whenmymotherreturnedlastnight,I____abook.A.readB.amreadingC.wasreadingD.amgoingtoread14.What____you____whenitbegantorain?A.do,doB.were,doingC.are,doingD.did,do15.I'llwakeyouupwhenhe____back.A.willB.isgoingtocomeC.comesD.comeAnswers：1---5CDBAD6---10DAACB11---15CBCBC二、用所給詞的適當(dāng)形式填空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.26.Lana_____(buy)anewdressiftheoldone____(be)outofstyle.7.Thetwins_______(fight)ifthey__________(argue).8.I______(have)abakesaleifI____(need)moneyforeducation.9.Peter____(send)meabeautifulsouvenirifhe____(visit)Spain.10.IfMr.Green_______(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.Answers：doesn'twork4willdresses,3are,willbehassee2willwillhave，1feel8willhave,need6willbuy,willkeep5lives,is7willfight,argue9willsend,visits10says,willfeeldoesn'train11willgo,passes14gets,won't15willmajor,gets12Willhaveis13willwrites,III完成句子What_______________ifhe_____________late?如果他到得晚了，會發(fā)生什么事情？1.Ifyou_________________,you________good________.你就會取得好成績。如果努力學(xué)習(xí)，2.3.他如果看電視太久了，他的父母會不高興。Ifhe_____TVtoolong,hisparents______________unhappy.如果我們?yōu)樗M織生日聚會，大家都會來的。4.Everyone________ifwe_______abirthdayparty________him.5.如果明天不下雨，我會和你一起去公園的。Ifit___________tomorrow,I_____gotothepark______you.如果她睡過頭了，就會上學(xué)遲到的。6.She____________________________ifshe__________Ifhe________,he__________you.如果他沒有空，他不會幫助你的。7.8.考試不及格，他就沒有機會上高中了。如果TomTom______havethe_____togotothehighschoolifhe________theexams.9.如果這個男孩打爛窗戶，屋主會對他生氣。Iftheboy_____________________,thehouseowner___________________________________.如果明天不下雨，我就出去野餐。10.__________________________________________________Answerssuccess.，willget3.watch,willbe2workhard,1.washappened，camelate?withwill,5doesn'train,4willcome,hold,forleepslate6willbelateforschool,schance8won'twon'thelp,'7isntfreefails9breaksthewindow,willbeangryathim10.Ifitdoesn'traintomorrow,Iwillgoouttohaveapicnic.31.Ifyoufeeltired,youshouldhavetohavearest.2.Wherehasheseenthefilmifhehastime?3.Iftherearefewertrees,therewillbemorepollution.4.Hewilldressmorecasuallyifhedoesn‘tworkonwee
