【考例1】（2023新高考II卷） They als need t be ready t give interviews in English with internatinal jurnalists. This is they need an English trainer.
答案与解析：why。考查表语从句。句意：这就是他们需要英语培训师的原因。分析句子结构可知，空处引导表语从句，从句中结构完整，应该用连接副词连接，前文提到需要培训师的原因，此处是表达“这就是他们需要英语培训师的原因”之意，应用why引导表语从句。故填why。
【考例2】（2020江苏高考真题）It is nt a prblem __________ we can win the battle; it’s just a matter f time.
A. whetherB. whyC. whenD. where
答案与解析：A。考查主语从句。A. whether是否；B. why为什么；C. when什么时候；D. where在哪里。根据下文it’s just a matter f time可知，此处指”我们能否打赢这场战斗不是问题”，it是形式主语，whether引导的从句是真正的主语。故选A。句意：我们能否打赢这场战斗不是问题；这只是时间问题。
【考例3】（2020浙江高考真题）Over thusands f years，they began t depend less n culd be hunted r gathered frm the wild, and mre n animals they had raised and crps they had swn.
答案与解析：what。考查名词性从句。句意：在几千年的时间里，他们开始减少对我们从野外采集的猎物的依赖，而更多地依赖他们饲养的动物和播种的庄稼。分析句子，宾语从句部分缺主语，所以引导词应为“连接代词”。根据句意，此处缺“什么”之意。故填what。
【考例4】（2020天津高考真题）The student cmpleted this experiment t make cme true __________ Prfessr Jseph had said.
A. thatB. whatC. whenD. where
答案与解析：B。考查名词性从句。_________ Prfessr Jseph had said作make的宾语从句，该从句中，空处在从句中作said的宾语，表示”……所说的话”，因此应用what引导该从句。故选B。句意：为了使约瑟夫教授所说的成为现实，这个学生完成了这个实验。
【考例5】（2020年北京卷）Oliver says if yu're lucky enugh t have smene clse t yu wh enjys cking, ask them __________yu can jin in when it's pssible.
答案与解析：if/whether。考查名词性从句连词。____ yu can jin in when it's pssible.是宾语从句，从句成分完整，但缺“是否”的意思，故填if/whether。句意：问他们你是否有可能加入他们。
【考点扫描】
名词性从句有主语从句、宾语从句、宾语从句和同位语从句四种。现根据其引导词将其主要特性总结如下：
一、名词性that从句
由从属连词that引导的从句叫作名词性that-从句。that只起连接主句和从句的作用，在从句中不担任任何成分，本身也没有实义。名词性that从句在句中能充当主语、宾语、表语、同位语和形容词宾语，但是一般不作介词宾语。
【考例1】I truly believe ______beauty cmes frm within.（XXXX·北京卷）
A. that B. where C. what D. why
【答案与解析】A。本题考查宾语从句。从句部分不缺少任何成分，因此用that起到连接作用，也可以省略。句意：我很相信美丽源自于内心!
【考例2】The nly way t succeed at the highest level is t have ttal belief _____ yu are better than anyne else n the sprts field. (XXXX·浙江卷）
A hw B that C which D whether
【答案与简析】B。本题考查同位语从句。belief所跟从句对其内容进行解释说明，是同位语从句。that引导同位语从句只起连接作用，不作任何成分，从句不缺成分。句意：在最高水平上取得成功的唯一方法就是要完全相信在那个运动场上，你比其他任何人都优秀。
【考例3】 Reading her bigraphy, I was lst in admiratin fr Dris Lessing had achieved in literature.(XXXX·陕西卷)
A. what B. that C. why D. hw
【答案与解析】A。本题考查宾语从句。介词fr后面是一个句子，因此是介词宾语从句，排除B；从句中及物动词achieve没有宾语，用连接代词what作其宾语。句意：读完了她的自传后，我对Dris Lessing在文学上所取得的成就佩服地五体投地。
二、名词性wh-从句
由wh-引导的名词从句叫作名词性wh-从句。wh-词包括wh, whm, whse, whever, what, whatever, which, whichever等连接代词和where, when, why, 以及hw,等连接副词。wh-从句的语法功能除了和that-从句一样外，还可充当介词宾语。如：
It caused them t think abut hw they might cntrl the experiences f children t prduce respnsible and prductive adults.
这让他们思考如何控制孩子们的经历，培养出负责任和有生产力的成年人。
【考例1】（2021年3月天津卷）What puzzles Lily's friends is ________ she always has s many crazy ideas.
A．whether B．whyC．whatD．when
答案与简析：B。考查表语从句。句意：令Lily的朋友们感到困扰的是她为什么总是有这么多疯狂的想法。A. whether是否；B. why为什么；C. what什么，所…的事儿；D. when什么时间，…的时间。分析句子，该空需要一个表语从句的连接词，结合句意，应该是朋友们不明白Lily 为什么有这么多疯狂的想法。所以本句为why引导的表语从句。故选B项。
【考例2】The pr wman wasn't able t give him any infrmatin abut __________she lived.（2021北京卷）
【答案与解析】where。考查宾语从句。介词abut后是宾语从句，根据句意，此处用where“在哪里；……的地方”符合句意，从句中作地点状语，故填where。句意：这个可怜的老妇人不能说清楚她住在哪里。
【考例3】（2018年6月天津）(2018·）The gld medal will be awarded t _______ wins the first place in the bicycle race.
A．whmeverB．whereverC．wheverD．whatever
【答案与解析】C。考查名词性从句连接词。分析句子可知，宾语从句中缺少主语，故用whever，表示“任何人，无论谁”。故选C。句意：无论谁获得自行车比赛第一名，金牌将授予他。
【考例4】 _____we understand things has a lt t d with what we feel.(XXXX·北京卷)
A. Where B.Hw C.Why D. When
【答案与解析】B。本题考查主语从句。根据句意可知，主语从句缺少方式状语，因此选择hw。句意：我们如何理解事情与我们所感受的有很大关系。
【考例5】 Sme peple believe _______ has happened befre r is happening nw will repeat itself in the future. (XXXX·北京卷)
A. whateverB. whenever C. wherever D. hwever
【答案与解析】A。本题考查宾语从句。及物动词believe后的句子是宾语从句，但是谓语动词has happened没有主语，用连接代词，只有A项是连接代词，其余选项都是连接副词，不能作主语。
【考例6】 Mental health invlves________ yu prcess things such as stress and anxiety.（2022年6月天津卷）
A．hwB．whatC．whyD．which
【答案与解析】A。考查名词性从句。分析句子结构可知，此处为连词引导的宾语从句作谓语动词invlves的宾语，从句中主语是yu，谓语动词prcess是及物动词意思是“处理、加工”，所跟宾语是things such as stress and anxiety, 这样看从句不缺少主语和宾语，但句意不完整，根据句意可知，表示“如何，怎样”的连词hw符合句意。故选A项。句意：心理健康包括如何处理诸如压力和焦虑之类的事物。
【考例7】The exhibitin tells us we shuld d smething t stp air pllutin.（XXXX·四川卷）
A. where B. why C. what D. which
【答案与解析】B。本句考查宾语从句的引导词。宾语从句中不缺少主语和宾语，故选项C和D排除。根据意思：这个展览告诉了我们，我们为什么要阻止空气污染。如果说“我们在哪儿阻止空气污染”则不符合逻辑。故选B。
【考例8】 If yu swim in a river r lake, be sure t investigate is belw the water surface. Often there are rcks r branched hidden in the water.（XXXX·浙江卷）
A. what B. wh C. that D. whever
【答案与解析】A。本句考查宾语从句。分析宾语从句的成分可以发现，空格是主语。指代的是树枝或石头，B项和D项指人，that 只有语法意义，不作成分。故选A。句意：如果你在河里或湖里游泳，请确定查看水面下有什么，通常总有一些石头或树枝藏在水里。
【考例9】A ship in harbr is safe, but that’s nt ______ ships are built fr. (XXXX·安徽卷)
A. whatB. whmC. whyD. when
【答案与解析】A。本题考查表语从句。is nt后跟从句作表语，表语从句中的fr后缺少宾语，用what引导，what与fr连用，表示目的。故选A。句意：船停放在海港里是很安全的，但这并非建造船的目的。
三、if和whether引导的名词性从句
从属连词if, whether引导的名词从句其功能和wh-从句的功能基本相同，但在下列情况用whether不用if：与不定式连用；在whether …… r nt 的固定搭配中；作介词宾语；宾语从句放在句首表示强调时；引导主语从句；引导表语从句；引导同位语从句。
【考例1】Cbb, fr her party, started t ask cnference rganizers wh invited her t speak she culd d s remtely; abut three-quarters f the time, they agreed.（2022年浙江1月卷）
【答案与解析】whether或if。考查宾语从句。句意：对于她的出席，Cbb开始询问邀请她的组织者是否可以远程进行。显然ask后面出现了一个宾语从句，宾语从句句意不完整，whether/if“是否”符合语境，故填whether或if。
【考例2】It desn’t matter ____ yu turn right r left at the crssing—bth rads lead t the park. (XXXX·天津卷)
A. whether B. hw C. if D. when
【答案与简析】A。本句考查主语从句。it是形式主语，横线后才是真正的主语，根据r提示用whether引导主语从句。
【考例】（2017年6月天津卷）She asked me ________ I had returned the bks t the library, and I admitted that I hadn’t.
A．when B．where C．whether D．what
答案与解析：C。考查宾语从句。句意：他问我是否已经把书还给图书馆了，我承认我还没有还。A. when什么时候；B. where在哪里；C. whether是否；D. what什么。根据句意，故选C。
四、形式主语和宾语it
（一）通常主语从句比较长，为了避免句子的头重脚轻，保持句子平衡，常常用it作形式主语，真正作主语的主语从句后置。后置的常是 that引导的主语从句，也可以是what, whether等引导从主语从句。如：
T seek what is impssible is madness: and it is impssible that the bad shuld nt d smething f this kind.
追求不可能的即疯狂：恶人让他们不作恶都不可能。（其中it是形式主语，真正的主语是that the bad shuld nt d smething f this kind）
It is nne f yur business what ther peple think abut yu. Believe yurself.
别人怎么看你，与你无关，相信你自己。（其中It是形式主语，真正的主语是what ther peple think abut yu.）
【考例】（2020江苏卷）It is nt a prblem __________ we can win the battle; it’s just a matter f time.
答案与解析：whether。考查主语从句。A. whether是否；B. why为什么；C. when什么时候；D. where在哪里。根据下文it’s just a matter f time可知，此处指”我们能否打赢这场战斗不是问题”，it是形式主语，whether引导的从句是真正的主语。句意:我们能否打赢这场战斗不是问题；这只是时间问题。
（二）当不定式、动名词、从句等复杂成分用作宾语且其后跟有宾语补足语时，通常会在宾语补足语前使用形式宾语it,而将真正的宾语移至句末，其基本结构为“动词+it+宾语补足语+不定式(动名词或从句)”。如：
I find it difficult t d the jb well.我发现做好这件事不容易。
I think it best that yu shuld stay here.我认为你最好住这儿。
We think it n use cmplaining.我们认为抱怨是没有用的。
但是，以下几种形式宾语比较特殊，同学们需引起注意(同时它们也是高考的常考考点):
1. 动词+ it + that-从句。能用于此结构的动词不多，常见的有have, take, put, like等。如：
I like it that yu came. 你来了，我很高兴。
I take it (that) he will cme n time. 我认为他会准时来的。
Yu can put it that it was arranged befre. 你可以说这是以前安排的。
Rumr has it that the defence minister will sn resign. 据传闻，国防部长不久就要辞职。
2.动词+ it +when (if)-从句。用于此结构的动词不多，常见的有enjy, hate, lve, like, dislike, appreciate, prefer等。如：
I dislike it when yu whistle. 我不爱听你吹口哨。
We really appreciate it when she ffered t help. 她来帮忙了，我们十分感激。
I'd prefer it if I didn't have t d s much wrk.要是我不必做那么多工作，好就太好了。
We wuld appreciate it if yu can cmmunicate with thers by cpying, telephne and fax!
【误用】I hate when they with their muths full f fd.
【指正】hate 后加上it。
有些动词不直接跟宾语从句，带宾语从句时需要在宾语与从句前加it，这类动词主要是：hate, take(认为), we, have, see t(负责，务必使…), appreciate等。
3.动词+ prep + it + that-从句。用于此结构的动词不多，常见的有see t, lk t, insist n, stick t, depend n,answer fr等。如：
See t it that yu're nt late again.注意千万不要再迟到。
Lk t it that this desn't happen again.注意不要再发生这种事。I can't answer fr it that he will cme.我不能保证他会来。
Yu may rely n it that he'll cme t meet yu.你放心，他会来接你的。
4.动词+ it +介词短语+ that-从句。如：
I we it t yu that I am still alive.多亏有你我才仍然活着。
I tk it fr granted that he wuld help us.我认为他会帮助我们的。
See t it that all the dishes are cleared away immediately after lunch.
