22.[2019·北京卷]Whatstudentsdoatcollegeseemstomattermuchmorethan________theygo.答案与解析:where 考查宾语从句。在介词than后用where引导宾语从句,where在从句中作状语。此处表示“学生在大学里做什么事似乎远比在哪里上大学更加重要”。
33.[2019·江苏卷]Scientistshaveobtainedmoreevidence________plasticisfindingitswayintothehumanbody.答案与解析:that 考查同位语从句的引导词。句意:科学家已经获得了更多的证据,证明塑料正在进入人体。分析句子结构可知,空格处引导同位语从句,解释说明evidence的具体内容,从句中不缺成分,故用that引导。
44.[2018·北京卷,11]Withouthissupport,wewouldn'tbe________wearenow.答案与解析:where 句意为:要是没有他的帮助,我们就不会是现在的情形了。本题考查表语从句。根据句意可知,设空处意为“情形,情况,形势”,应用where引导。

8B组 单句改错1.[2016·四川卷]ThedisheswhatIcookedwereMom'sfavorite.________答案与解析:what→that/which或去掉what 先行词dishes在定语从句中作宾语,故应用that或which引导,也可省略关系代词。
92.[2016·全国卷Ⅰ]MyuncleistheownerofarestaurantclosetothatIlive.________答案与解析:that→where to后为宾语从句,引导词在从句中需作地点状语,表示“靠近我居住的地方”。故that→where。
103.[2016·全国卷Ⅱ]MyclassmatesandIaretalkingabouthowtododuringtheholiday.________答案与解析:how→what 从句中的do是及物动词,故应用连接代词what作动词do的宾语。
11考点研析考点一 主语从句1.引导主语从句的词有:连接词that,whether;连接代词what,who,whose,whatever,whichever,whoever等;连接副词when,where,why,how。①Whenthedelayedflightwilltakeoffdependsmuchontheweather.延迟的班机何时起飞在很大程度上取决于天气。②Thattheywereintruthsisterswasclearfromthefacialsimilaritybetweenthem.从她们的面貌相似度就能清楚地看出是亲姐妹。
12③Whatstruckmemostinthemoviewasthefather'sdeeploveforhisson.影片中最打动我的是父亲对儿子深厚的爱。【易混辨析】 whether与if引导主语从句的区别:主语从句位于主句谓语动词前,表示“是否”,只能用whether而不能用if引导;若用it作形式主语,则if与whether可互换。
13④Whetherwecanhavecleandrinkingwaterliesinwhateffectivemeasureswillbetakenbythegovernmentaboutwaterpollution.我们能否有干净的饮用水依赖于政府将采取什么样的有效措施处理水污染问题。⑤Itremainstobeseenwhetherornotthisideacanbeputintopractice.这一想法能否付诸实施还有待观察。

17(2)it作形式主语,连接代词、连接副词或whether/if引导的主语从句作真正的主语。Itisuncertainwhatsideeffectthemedicinewillbringabout,althoughabouttwothousandpatientshavetakenit.尽管大约两千名患者已经服用了这种药,但是它会带来什么样的副作用还不清楚。Itisnotimmediatelyclearwhether/ifthefinancialcrisiswillsoonbeover.经济危机是否会很快结束,短时间内不会很明显。

27考点三 宾语从句1.that连接宾语从句时通常可以省略(但多个并列的宾语从句中只能省略第一个that),没有具体的意思,不充当句子成分,只是起连接作用。what引导时,在从句中充当成分,且有意义。[全国卷Ⅰ]I'mwritingtotellyouthatmyuncleLiMingisgoingtoyourcityforaconference.我写信是想告诉你,我叔叔李明要去你的城市开会。
282.在whether/if连接的宾语从句中,whether/if意为“是否”,但在whether...ornot结构中,或者whether引导的宾语从句作介词的宾语时,以及whether+todo结构中和whether引导的从句作少数动词(如leave,put,discuss,doubt,know等)的宾语时,只能用whether,不能用if来替换。We'veofferedherthejob,butIdon'tknowwhethershe'llacceptit.我们已经为她提供了这份工作,但我不知道她是否会接受。
