__________thatthatifwhetherwhetherthat,if和whether引导的宾语从句在一个主从复合句中，若从句作宾语，则该从句为宾语从句。本单元探讨that,if和whether引导宾语从句的情况。宾语从句引导词的主要功能是连接主句与从句，并引导从句在主句中作宾语，是宾语从句的标志。考点1that引导的宾语从句的基本意义及用法that无实际含义，that在句中不充当成分，仅起连接作用，用于引导由陈述句转化而来的宾语从句（肯定或否定）。口语中常省略，常见于think,say,know等动词后。·Iknow(that)heisfromCanada.我知道他来自加拿大。考点2if与whether引导的宾语从句的基本意义及用法二者核心意义均为“是否”，用于引导由疑问句（一般疑问句或选择疑问句）转化而来的宾语从句，从句需用陈述句语序（主语在前，谓语在后）。·Idon’tknowifitwillraintomorrow.我不知道明天是否会下雨。·Weneedtodecidewhethertohaveapicnicthisweekend.我们需要决定这个周末是否去野餐。考点3if与whether引导宾语从句的异同对比维度if引导的宾语从句whether引导的宾语从句核心意义表示“是否”表示“是否”引导从句类型仅可引导由一般疑问句转化的宾语从句可引导由一般疑问句或选择疑问句转化的宾语从句对比维度if引导的宾语从句whether引导的宾语从句是否可与or连用不可连用可连用。例：Iwonderwhetherhewillcomeornot.我想知道他是否会来。是否可用于介词后不可可。例：Itdependsonwhetherwehavetime.这取决于我们是否有时间。是否可引导不定式结构不可可。例：Hehasn’tdecidedwhethertogo.他还没决定是否去。小贴士：that引导宾语从句时，有时不能省略。（1）当有多个并列的宾语从句时，第一个that可省略，后面的that不可省略（避免混淆多个从句的界限）。·Shesaid(that)shelovedpaintingandthatshewouldtakeclassesnextmonth.她说她喜欢画画，还说下个月要去上课。（2）当主句谓语动词是表示“命令、建议、要求”等意义的动词（如order,command,suggest,request等）时，that不可省略，且从句需用“should（可省略）+动词原形”的虚拟语气，强调从句的正式性和严肃性。·Themanagerorderedthatallstaff(should)attendthemeetingontime.经理命令所有员工准时参加会议。（3）当主句和宾语从句之间有插入语时，插入语会隔断主句与从句，that需保留以明确从句起点。·Webelieve,asmanyexpertshavesaid,thatregularexerciseimprovesmentalhealth.正如许多专家所说，我们相信定期锻炼能改善心理健康。一单项选择1.—What’swrongwithyourcomputer?—I’msure______thereissomethingwrongwithit,butIwonder______itcanberepaired.A.that;that B.that;whetherC.if;whether D.whether;thatB2.[江苏南京模拟]—Thatoldmanlooksweakthesedays.—Yes.We’resure______somethingiswrongwithhimandwedoubt______thediseasecanbecured.A./;whetherB.that;thatC.whether;ifD.if;whether3.—Whatdidtheshopkeepersaytoyou?—Sheaskedme______.A.whendidtheshopclose B.whatelseIwillbuyC.ifIpreferredthatT-shirtAC4.[湖北武汉一模]—ThepoetLiBaiwrote“FarewelltomydearfriendatYellowCraneTowerinthewest.He’sboundforYangzhouinMarchwhenspringisatitsbest.”—Thefamouslinesuggests______.A.howbeautifulistheYellowCraneTowerB.thatgoodbyesinspringcanbesadbuthopefulC.whyisMarchthebesttimetosaygoodbyeD.wheretotravelwhenpeoplehaveavacationB5.[四川成都二模]—DidMomsayanythingaboutmyhomework?—Yes,sheremindedme______youmustfinishitbeforedinner.A.that B.what C.ifA二根据句意及汉语提示完成句子6.导游说这座城堡有500年历史了。Theguidesaid____________________________500yearsold.7.你能告诉我这家咖啡馆有没有素食选项吗？Couldyoutellme________________________________veganoptions?thatthiscastlewasif/whetherthecaféhas8.他们争论派对应该在室内还是室外举行。Theydebated_________thepartyshouldbeindoors_______________.9.孩子问星星是真的在闪烁，还是只是看起来那样。Thechild______________starsreallytwinkleorjustlookthatway.10.我认为学一门语言能打开新的大门。Ithink_______________________canopennewdoors.whetheroroutdoorsaskedwhetherlearningalanguage三、语法填空（语篇练语法）LiLei’sWeekendPlanLiLeiwantstogooutwithhismomthisweekend.Thismorning,hetalkstohismomaboutit.“Mom,Iwonder11.___________wecangotoGreenParkthisSaturday,”LiLeisays.Hismomsmilesandasks,“Doyouknow12.________therewillbeaflowershowinthepark?”LiLei’seyeslightup.if/whetherthat“Yes!IheardfromTom13.________theflowershowstartedlastFridayandwilllastfortwoweeks,”heanswers.ThenMomasks,“Doyouknow14.________theparkopensinthemorning?Ineedtopreparebreakfastfirst.”LiLeishakeshisheadandsays,“Idon’tknow.ButIcancalltheparktocheck15.________itopensat8:00a.m.ornot.”Momnodsandtellshim,“Remember16.________weshouldtakeanumbrella.Theweatherreportsaysitmayrain.”thatwhenwhetherthatLiLeisayshappily,“OK!Andcanyoutellme17._________Icanbringsomesnacks?”“Ofcourse,”Momreplies.“Wecanalsotakesomefruit18.________ourpicnic.”LiLeiadds,“I’llinvitemybestfriendPeter,too.Helovesflowersho
