意为“如果”，引导条件状语从句时，既可放在主句前面，也可放在主句后面。若if条件句放在句首，从句后面要加逗号与主句隔开。Ifyougothere,I’llgo,too.如果你去那儿，我也会去。Mymotherwilltakemetotheparkifsheisfree.如果我妈妈有空，她就会带我去公园。2.时态：(1)

主句是一般将来时，if从句用一般现在时表示将来。Ifhecomes,hewillbringhisviolin.如果他来，就会带上他的小提琴。(2)

主句用情态动词表示可能的结果时，if从句用一般现在时。Ifyouwanttoloseweight,youmusteatlessbread.如果你想减肥，就必须少吃面包。Youcangetgoodgradesifyoustudyhard.如果你努力学习，就可以取得好成绩。(3)

主句是祈使句时，if从句用一般现在时。Ifyouarenotstrongenough,pleasedon’ttakepartinsuchanactivity.如果你不是很强壮，请不要参加这种活动。3.句型转换：(1)

if引导的条件状语从句可与“祈使句+and/or+陈述句（一般将来时）”转换。其中，在句意上and表示顺承；or表示转折，意为“否则”。Ifyouworkhard,you’llpasstheexameasily.=Workhard,andyou’llpasstheexameasily.努力学习，你将很容易通过考试。(2)

借助without或with来转换条件状语从句。Ifthereisnoairorwater,peoplecan’tlive.=Peoplecan’tlivewithoutairorwater.如果没有空气和水，人们将无法生存。Ifyouhelpme,I’llfinishtheworksoon.=Withyourhelp,I’llfinishtheworksoon.如果你帮助我，我将很快完成工作。if引导的从句类型的区分及词义的区分1.动词+if+宾语从句，if翻译成“是否”，时态按宾语从句的时态规律进行选择—DoesTimtellyouifhe________tomorrow?—No,hedoesn’t.Butifhe________,I’llcallyou.A．willcome;willcome B．willcome;comesC．comes;comes D．comes;willcome2.主句+if+条件状语从句，if翻译成“如果”，时态遵循“主将从现”原则。Iwillgotothepartyifheinvitesme.如果他邀请我，我就会去参加晚会。Pleasecallmeatonceifhecomesback.如果他回来了请立刻给我打电话。注意：if/when引导状语从句和宾语从句这时，从句的时态：ifWhenif/when从句的时态条件/时间状语从句如果、假如当……的时候一般现在时宾语从句是否什么时候一般将来时真题感知1．（2023·湖南湘西·统考中考真题）Wildanimalswillbeingreatdanger________weprotectthemtogether.A．if B．but C．unless2．（2023·甘肃甘南·统考中考真题）—IwonderifLiHua________tothehospitaltoreceivethevaccination（疫苗接种）.—Iamsurehewillifhe________time.A．goes;willhave B．willgo;has C．willgo;willhave3．（2023·江苏常州·统考中考真题）Asweliveinarapidlydevelopingworld,wewillbeleftbehind________wekeeplearning.A．unless B．if C．after D．though4．（2023·黑龙江哈尔滨·统考中考真题）Foroursafety,wemustkeepawayfromthetallbuildings________thewindblowshard.A．if B．although C．so5．（2023·湖北宜昌·中考真题）—Lucy,theDragonBoatFestivaliscoming.Iwanttolearnhowtomakezongzi.—OK.Ifmygrandma________freetomorrow,shewillteachus.A．is B．are C．am D．willbe6．（2023·辽宁抚顺·统考中考真题）Myparentswon’tallowmetodothingsIlike________Ifinishmyhomework.A．if B．but C．because D．unless7．（2023·河北·中考真题）Itisreallydangerous_______peopleruntheredtrafficlight.A．if B．unless C．though D．until8．（2023·黑龙江·中考真题）ZhangGuimeioncesaid,“________I’malive,Iwilldonate(献身)myselftoteaching.”A．Eventhough B．Assoonas C．Aslongas9．（2023·湖南岳阳·中考真题）Youwon’tpassthePEexamsuccessfully________youexerciseeveryday.A．if B．unless C．aslongas10．（2023·安徽·中考真题）Ourcountrywillbemuchbetterforeveryoneinfuture________wealldosomethingtohelpnow.A．if B．before C．sothat D．eventhough11．（2023·四川成都·中考真题）________youtreatotherswithyourheart,youwillgetfriendshipinreturn.A．If B．Until C．Unless12．（2022·广西桂林·统考中考真题）Ifyou________alongthisroad,youwillfindapark.A．go B．went C．goes13．（2022·江苏盐城·统考中考真题）We’llhaveapicnicintheparkthisSunday________thereisaheavyrain.A．whether B．unless C．since D．because14．（2022·湖北黄石·统考中考真题）There________avolleyballgamenextSaturday.Ifit________we’llhavetoputitoff.A．isgoingtobe;rains B．isgoingtobe;willrainC．isgoingtohave;willrain D．isgoingtohave;rains15．（2022·江苏南通·统考中考真题）Maryisgoodatwriting.Iamsureshe’llgetagoodplace________shetakespartinthewritingcompetition.A．before B．if C．though D．unless16．（2022·广西百色·中考真题）Idon’tknowifit_________tomorrow,butifit_________,I’llstayathome.A．willrain;rains B．willrain;willrain C．rains;willrain D．rains;rains17．（2022·辽宁丹东·统考中考真题）—Canwewinthebasketballgametomorrow?—Ofcourse,_______wetryourbest.A．if B．or C．unless D．though18．（2022·辽宁盘锦·统考中考真题）Thelittleboywon’tgotosleepunlesshismom_________himastory.A．tells B．told C．istelling D．willtell19．（2022·黑龙江齐齐哈尔·统考中考真题）Learningtowriteislearningtothink.________,youwon’tknowthingsclearly.A．IfyouwritethemdownB．UnlessyouwritethemdownC．Ifyouwon’twritethemdown20．（2022·河北·统考中考真题）________youcanuseyourdictionary,youwilllearnEnglishbetter.A．If B．Unless C．Though D．Before提升专练一、单项选择1．—WillyougotoBob’sbirthdayparty?—No.________heinvitesme.A．If B．When C．Unless2．—Iwonderifhe________tothemuseumtomorrow.—Ifit________,hewon’tgo.A．willgo；willrain B．willgo；rains C．goes；willrain3．Evenifwelearnsomethingwell,wewillforgetit________weuseit.A．unless B．until C．as D．because4．Youmaydialthisnumber________yourunoutoffoodanddrinkduringyourstay.A．if B．until C．although D．because5．—Mary,ifTom________thefirstbustoschooltomorrow,what________tohim?—Ithinkhe’llcertainlybelateforclass.A．takes;willhappen B．willtake;happensC．doesn’ttake;willhappen D．won’ttake;ishappening6．________wekeepworkinghardeveryday,ourdreamwillcometrueoneday.A．Aslongas B．Although C．Until D．After7．—Wouldyouliketospendtimewithmethisweekend?—IfI’mfree,I________.A．do B．would C．am D．will8．—John,let’sprepareforourbasketballmatch.—OK,we’llloseit________wetryourbest.A．until B．unless C．if D．although9．—Ihavenoideaifmyfriend________tomyhousewarmingpartyintwodays.—Ifshe________,Iwon’tpickherupattherailwaystation.A．willcome;comes B．doesn’tcome;won’tcomeC．comes;doesn’tcome D．willcome;doesn’tcome10．Everybodycanhearyou________youspeakinaloudervoice.A．unless B．if C．sothat D．although11．—What’syourwintervocationplan?—IfI________highgradesinthefinalexams,I________toDaliforatrip.A．willget;willgo B．willget;go C．get;go D．get;willgo12．Wewon’tgototheparkifit________tomorrow.A．rain B．rains C．raining D．rained13．Youcanmakedeliciousfood________youfollowmyways.A．asmuchas B．aswellas C．asfaras D．aslongas14．WewillhaveapartyifTom________ourteam.A．willjoin B．joins C．joined D．isjoining15．—Mom,IwanttowatchtheTVProgramChina’sGotTalentnow.—Sorry,youcan’twatchit______youfinishyourhomework.A．unless B．so C．if D．
