一般说来，what/who等含特指意义，而whatever/whoever等含泛指意义，意为"无论什么/无论谁"。
It is generally considered unwise to give a child ____ he or she wants.
A. however
B. whatever
C. whichever
D. whenever
解析：答案是B，whatever引导一个宾语从句，并且作wants的宾语。这里的whatever 不能改成what，因为题意想表达的显然是"无论孩子要什么就给他/她什么事不明智的"，具有泛指的概念。同时要注意，这里whatever也不能改用no matter what，因为后者只能引导状语从句。比较下例：
I can't remember at the moment who has said the words. (这里的who表特定的某人)
Where, when, why等连接副词引导的名词性从句
Where, when, why等连接副词也能够引导名词性从句，使用的关键是：这个词必须符合句子的逻辑要求。
-I drove to Zhuhai for the air show last week.
-Is that ____ you had a few days off?
A. why
B. when
C. that
D. where
解析：答案是A，why引导的从句作表语，同时why在从句中作原因状语。这里之所以选why，而不是when或where等，唯一的依据便是句子的逻辑含义，及语境。
"介词+who(m)引导的宾语从句"与"介词+ whom"引导的定语从句的区别
介词后面的引导词用主格还是宾格，决定于它在宾语从句中作主语还是宾语。
It was a matter of ____ would take the position.
A. who
B. whoever
C. whom
D. whomever
解析：答案是A。这是一个含宾语从句的复合句，作介词of宾语的，是后面的整个句子，而不是宾语从句的引导词，因为这里引导词在从句中作主语，所以要用主格who(作宾语时自然要用whom)。
名词性从句中有插入成分时
此时应注意两点：一是从句仍然不倒装，而在插入成分上倒装；二是要注意主语的主格和宾格的选择。
____ you have seen both fighters, ____ will win?
A. Since; do you think who
B. As; who you think
C. When; whoever
D. Since; who do you think
解析：根据上面的讲解，不难知道答案是D。其中do you think是插入成分，其余部分是宾语从句，作think的宾语；因为引导词在从句中作主语，所以要用主格who(不用whom)。
引导词that的省略
引导宾语从句时，that通常能够省略，但引导主语、表语和同位语从句时，that不能省。例如：
China's success in manned-spacecraft travel shows ____ our country has become one of the greatest powers in space research.
A. what
B. which
C. 不填
D. it that
解析：该句中的从句作shows的宾语，是宾语从句，又因为从句中不缺主、宾语，所以只能用that引导；又因引导宾语从句时that能够省略，所以答案是C。
同位语从句引导词where, when的用法特点
说明先行词内容的同位语从句的引导词where, when与被说明的名词在概念上不一致。但引导定语从句的引导词却必须保持一致。试比较：
1.Then arose the question ____ we were to get so much money.
2.This the house ____ the great man Mao Zedong was born 110 years ago.
A. where
B. that
C. about which
D. in which
解析：答案分别是1.A 2.A/D。先行词与where, when概念一致时，是定语从句，2题中的house与where同表地点，且这个关系副词where或when能够用"介词+which"的形式代替，所以答案A 和D都能够引导。1题中的question与where不表同一概念，可见是同位语从句，所以where不能改用"介词+which"的形式。

定语从句整理 定语从句分为限定性和非限定性 1.定语从句修饰先行词 2.关系代词：that, who, whom, whose, which, as 关系副词：where, when, why 3.关系词在句中的作用1. 引导定语从句 2. 代替先行词3.在定语从句中担当一个成分 4.关系代词在从句中做主语或者宾语； 5.关系副词做状语，相当于：介词+which。 when是时间状语，where是地点状语，一些特殊先行词后面也用where，比如 point, situation, part, condition,case 表示到了某种地步，某种程度也用where. * where和when都可以换成介词+which，但是不是所有介词+which都可以换成where或者when。 *不是所有介词都可以放在which或者whom前面，一些动词短语比如：look for, look after，take care of turn in, pay attention to, depend on, listen to就不能拆开使用，且介词后面不能用who或者that 关于关系词的省略 1)who, whom, that, which, 做宾语时可省。 2)that做表语可省 be动词后 3)that做宾补可省 4)*关系副词when在time, year, day后面可省，也可换成that,但不 普遍 5)*关系副词where在place, 和anywhere, somewhere这种--where 的后面时候可以省略，也可换成that但不普遍 6)*关系副词why放在the reason后面，即可换成 for which, that 又可省略，此较普遍。但放在a reason后面可省，但貌似不可以换成that 7)the way后面可以用in which, that 也可省略 关于that 可以用that的情况； that 在定语从句中的功能非常多 1.可以代词关系代词 who, whom, which, 既可以做主语又可以做宾语，做宾语时可以省略；限从中可以说遇到关系代词就可以换成that， whose除外，因为whose的名词所有格（。。。的）whose= of which 2.关系副词why修饰the reason可换成that,也可省。 Notice:见到the reason不一定非要选why, 做宾语时候选which/that, 也可省。 3.that在某些特殊情况下代替 where， when但不普遍。 4.the way后面可以用in which, that 也可省略 必须用that的情况 (做宾语依旧可省） 1.先行词是不定代词 everything, anything, nothing, 等不定代词 *不含something 2.先行词被every, any, all, some, no, little, few, much等限定词修饰 3.先行词被序数词修饰 the first, the second..... 4.先行词被最高级修饰 the best, the most 5.先行词被the very, the most修饰时
解题思路 1.通读全句。首先判断是什么句型。 2.题干句如果是疑问句式，将其转化为陈述句式。 3.分析从句的句子结构，在定语从句中，缺什么，就补什么：缺主或宾语，用关系代 词；缺状语，用关系副词 4. 注意标点符号和题干中是否存在并列连词and, but等。 常见考点 1.指物时只用that 或which 的情况 2.介词+关系代词 3.Whose 用法及转换形式 4.as 与which的区别 5.指人时that 与who的区别 6.如何判断用关系副词还是关系代词 7.定语从句中的主谓一致问题 1. This is all ____ I know about the matter. A. that B. what C. who D. whether 2. Is there anything else _____ you require? A. which B. that C. who D. what 3. The last place _____ we visited was the Great Wall. A. which B. that C. where D. it 4. He talked happily about the men and books _____ interested him greatly in the school. A. which B. that C. it D. whom 5. There is no dictionary _____ you can find everything. A. that B. which C. where D. in that 6. Is oxygen the only gas _____ helps fire burn? A. that B. / C. which D. it 7. Which was the hotel _____ was recommended to you? A. that B. which C. where D. it 考点一:that 与which 的区别 1. 先行词为all, little, much, everything, nothing, something, anything等不定代词 2.先行词被all, little, much, every, no, 等修饰时 .3先行词被序数词或最高级修饰先行词前有序数词(the first),形容词最高级(the best), the last, the very, the only 等时。 4. 先行词为人和物的组合 5.若主句中有疑问代词who 或者which，为了避免重复, 关系代词不要再用who, which，而用that。 考点二:介词+关系代词 提醒: 介词﹢关系代词引导的定语从句, 关键 是判断介词的选择. 方法一:根据从句中动词与先行词习惯搭配 方法二:根据从句中动词与先行词的逻辑关系 注意：关系代词在定语从句中作介词宾语时，从句常常由“介词+关系代词”引出。此时关系代词只能用which 或whom; 不可用that 或who 代替
名词性从句考点纳 概念: 在整个句中起名词作用的从句,包括主语从句、宾语从句、表语从句和同位语从句。 判断： 主语从句在谓语动词前，且常用形式主语it 宾语从句在动词、介词、形容词后 表语从句在系动词后（be, seem, look等） 同位语从句在名词后且引导词在从句中不作成分 连接词分为三类： 从属连词：that, (不充当从句的任何成分, 不可省，没有意义 whether/ if (不充当从句的任何成分，不可省，“是否”的意思) 连接代词：what(ever), who(ever), whom(ever), which(ever),whose: 充当主、宾、表、定 连接副词：when, where, how, why (充当状语) 名词性从句的做法 1.判断 2.从句中缺什么给什么 考点一：what vs. that what 在句中充当成分，后面跟意思是： that在从句中充当成分，后面跟，意义 you have done might do harm to other people. you don’t like him is none of my business. 考点二：that 的省略 ●由连接词that引导从句时，that 在句中不担任任何成分，在口语或非正式 的文体中常被省去，但是，从句是并列句时，第二个分句及以后的分句前的that 。 He told me (that) he will go to Shanghai tomorrow and he will visit many sights. ●that位于句首引导主语从句时，不能省略。 He will win the match is certain. It is certain that he will win the match. he will win the match is certain.
中考九年级英语定语从句完整归纳 一、定语从句 1．Kids，I hope you’ll remember the good old days____we spent together in junior high though it’s time to say goodbye. A．who B．what C．which 【答案】C 【解析】 【详解】 句意：孩子们，虽然到了说再见的时候了，我希望你们将记住那些我们一起在初中度过的美好的旧时光。who关系代词，引导定语从句，先行词指人，在从句中作主语或宾语；what什么，不能引导定语从句；which关系代词，引导定语从句，先行词指物，在从句中作主语或宾语。根据句子结构可知，这里考查定语从句，先行词是the good old days，从句中spent后缺少宾语，应用关系代词which引导，故应选C。 2． My grandparents like stories ________ have happy endings. A．they B．who C．which D．/ 【答案】C 【解析】 【详解】 句意：我爷爷奶奶喜欢有快乐结局的故事。考查定语从句。先行词stories（故事）表示物，需用关系代词that或which，引导词同时做从句的主语，根据句意结构，故选C。 3．On Monday April 15， 2019， the fire_______broke out in Notre Dame Cathedral in Paris shocked the world． A．that B．who C．where 【答案】A 【解析】 【详解】 句意：2019年4月15日，周一，巴黎圣母院发生的大火震惊了全世界。 A. that先行词是人或物， B. who先行词是人； C. where先行词是地点名词。本句先行词是fire，指物，在定语从句中作主语，关系代词用which/that。故答案为A。 【点睛】 在定语从句中，关系代词所代替的先行词是人或物的名词或代词，并在句中充当主语、宾语、定语等成分。关系代词在定语从句中作主语时，从句谓语动词的人称和数要和先行词保持一致。 1） who, whom, that这些词代替的先行词是人的名词或代词，在从句中所起作用如下： Is he the man who/that wants to see you? 他就是想见你的人吗?（who/that在从句中作主语）

He remembered the weekends ____ he climbed mountains. We took a picture_____ there is a tower. A. What B. when C. that D. where E. which 考点一:如何判定用关系代词还是用关系副词 worked together. 1.I’ll never forget the days________________ we 2.I’ll never forget the days ___________ we spent together. 3.I went to the place I worked ten years ago. 4.I went to the place __________ I visited ten years ago. 5.This is the reason ___________ he was late. 6.This is the reason ____________ he gave. 考点二只用that不用which ①当先行词为all, much, little, few, none, something, anything, everything, nothing等不定代词时 ②先行词被all, every, no, some, any, little, much修饰时： ③先行词是序数词或形容词最高级修饰时。 ④先行词被the only, the very, the last 修饰时。 ⑤当有两个或两个以上分别表示人和物的先行词时，这个定语从句要用that而不用who (whom)和which引导。如： (6)为了避免重复。前面有who 用which不用that
名词性从句考点及易错点归纳总结 考点：关系词的选用 原则：缺啥补啥，补缺用连接词或连接副词，具体选择看句意 易错点： 1.名词性从句关系词的省略问题：除了宾语从句可以省略that关系词外，其他的都不行。另需注意宾语从句如有两引导词that，则第一个可省，第二个不可。 2.主语从句及宾语从句常考的几个形式主语\宾语结构 （一）it作形式主语的常见句型： (1)It＋be＋形容词(necessary/likely/important/certain等)＋that从句 (2)It＋be＋名词(短语)(a pity/a shame/no wonder等)＋that从句 (3)It＋be＋过去分词(said/told/reported等)＋that从句 (4)It＋不及物动词(seem，appear，happen，matter等)＋that从句 （二）形式宾语 宾语一般放在及物动词或介词之后，但是，在下列情况下，须用it作形式宾语，而将真正的宾语(常为不定式/从句)后置。
(1)动词find/feel/think/consider/make＋it＋宾补(形容词或名词)＋不定式/从句 (2)动词hate/ like/ dislike/ appreciate/enjoy＋it＋从句 (3)短语动词see to/ depend on/rely on＋it＋从句 (4)固定搭配take it for granted that/owe it to sb.that＋从句 3.if 与whether 的异同 只用whether的情况： （1）主语从句位于句子开头 （2）介词后的宾语从句； （3）引导表语从句或同位语从句； （4）与or not连用； （6）与to do 连用 3. 语序问题：含有疑问意思的语序用陈述语序 4. 时态问题：与主句保持一致，但客观真理需用一般现在时。 5. 名词性从句的虚拟语气问题→that sb (should) do 6. 其他常考的表语从句 (1)This/ That/ It is why＋表语从句(表结果)“这/那就是……的原因” (2)This/ That/ It is because＋表语从句(表原因)“这/那是因为……” (3)The reason why...is that＋表语从句“……的原因是……” 7. 同位语从句与定语从句的区分 同位语从句在句中作某一名词的同位语，位于该名词之后，用以说明该名词的具体内容。定语从句则是对于从句中的某一名词进行修饰。 常见同位语从句的名词：advice，conclusion，doubt，fact，hope，idea，news，promise，question，suggestion，thought，truth，wish，word等。引导同位语从句的引导词：that，whether，how，where，when，why等。 The manager put forward a suggestion that we should have an assistant.There is too much work
【英语】名词性从句考点解析（Word版附答案）（word） 一、名词性从句 1．We believe ________ you have been devoted to ________ naturally of great necessity. A. that; being B. all that; be C. that all; are D. what; is 【答案】 D 【解析】【分析】句意：我们相信你所投入的当然是非常必要的。分析句子可知，believe 后接宾语从句，宾语从句中you have been devoted to缺少宾语，表示事物故用what；what you have been devoted to为主语，从句作主语，谓语动词用单数，故选D。 【点评】考查名词性从句和主谓一致，本题涉及what引导的主语从句和一般现在时。 2．Some people believe _______ has happened before or is happening now will repeat itself in the future. A. whatever B. whenever C. wherever D. no matter what 【答案】 A 【解析】【分析】句意：一些人认为之前发生的或现在正在发生的任何事情在将来都会重复发生。Whatever has happened before or is happening now是一个主语从句，whatever既引导起这个主语从句，也在句中做主语。BC项都属于副词的性质，都不能做主语，通常只能做状语；no matter what只能用来引导状语从句，故选A。 【点评】考查名词性从句，本题涉及"特殊疑问词+ever"引导的主语从句。 3． is even more important is the earth cooled down, water began to appear on its surface. A. When; that; when B. What; whether; as C. What; that; as D. lt; whether; as 【答案】 C 【解析】【分析】这题考查从句的用法，第一空填what引导主语从句，在主语从句中what做主语，第二空填that引导表语从句，在表语从句中，as是引导时间状语从句，句意是：甚至更重要的是：随着地球的冷却，水开始出现在表面。选C。 4．In the past decade, our education system too much on grades. However, grades have a direct connection with future success is still a question. A. focused; whether B. focused; if C. has focused; whether D. has focused; if 【答案】 C 【解析】【分析】考查时态和主语从句。根据In the past decade,在最近的几十年里，可知句子用现在完成时态，our education system是句子的主语，单数形式，所以第一空填has focused；第二空是主语从句做主语，if是否，不能引导主语从句，所以第二空填whether。故选C。
高考英语定语从句常见考点归纳 定语从句是中学英语教学的重点，也是学生学习的难点，同时又是高考考查的热点。纵观近年各地高考试题，就能发现考点大多集中在带有"插入语"的定语从句；which 、as 引导的非限定性定语从句；where 、when引导的定语从句以及定语从句和强调句、同位语从句的区别等方面。 对定语从句的考查不单纯考查其语法结构，而是把它融入到一定的语境中，考查考生的实际综合运用能力。 高考试题中，主要从以下角度考查定语从句： 定语从句的考点之一 that用法 正确区分关系代词that引出的定语从句功能强，除不能作定语(用whose)外，其它几个功能都可用that。但命题角度主要以that与which指物时的区别为重点进行命制。例如： （1）——Do you have anything in mind _________ you’d like for supper? ——Well, _________ is OK with me. A. that ; anything B. which ; everything C. what ; whatever D. where ; something 选A。 （2）The wrong you've done him is terrible, for ______ you should make an apology to him, I think. A. this B. which C. what D. that 选B。 定语从句的考点之二 判断成分，是关系代词还是关系副词 正确区分关系代词(that或which)与关系副词when(表时间)、where(表地点)、why(表原因)。 重点根据定语从句中所缺成分 （即关系词在定语从句中作状语时，使用关系副词when (on which); where(in which); why(for which)；在定语从句中作作主语、宾语或表语时，使用that或which。）来确定是用关系代词还是关系副词，绝不能因先行词是时间名词就用when，是地点名词就用where，是reason就用why来确定。 因此，认准先行词只是选择关系词的一个方面，更重要的是看其在后面定语从句中充当什么句子成分例如： （3）He should stand near the stage ________ he could watch and follow the play. A. where B. when C. that D. there 选A。 （4）Do you think the reason _______ he gave is believable. A. for which B. which C. why D. what 选B。 （5）We are living in an age _______ many things are done on computer. A. which B. that C. whose D. when 选D。

A. that B. which C. who D. where ③（10全国Ⅱ）I refuse to accept the blame for something ________was someone else’s fault. A. who B. that C. as D. what 2. 考查先行词是人，关系代词who,whom,that充当主语或宾语异同：在限定性定语从句中充当主语一般用who, that；充当宾语时三者可以互换或关系代词还可以省略；介词后的宾语,只能用whom等。 ①（06北京）Women _____ drink more than two cups of coffee a day have a greater chance of having heart disease than those ______ don’t.

2021年高考英语语法核心考点复习：名词性从句知识点 概述：名词性从句的功能相当于名词。根据其在句中充当的成分，可分为：主语从句、宾语从句、表语从句和同位语从句。 主语从句 在复合句中做主语的从句叫主语从句。引导主语从句的连词：that（无意义，所引导的主语从句是完整的），whether （是否），if （是否）（通常只能用于it作形式主语的主语从句），连结代词： who （谁）（主格）, whom （谁）（宾格）, whose（谁的）（所有格）, what （什么，所……的（东西或事情））, which （那个，那些），whoever （无论谁）（主格）, whomever （无论谁）（宾格）, whatever（无论什么）, whichever （无论那个，无论那些），连接副词： when（何时）, where （何地）, how （怎样，如何）, why （为什么）等。如： That the 2022 Winter Olympic Games will be held in Chengde is known to us all. =It is known to us all that the 2022 Winter Olympic Games will be held in Chengde. =What is known to us all is that the 2022 Winter Olympic Games will be held in Chengde. =As is known to us all, the 2022 Winter Olympic Games will be held in Chengde.
（直击高考）2013高考英语语法重难点系列专题10 名词性从句考 点 在句子中起名词作用的句子叫名词性从句(Noun Clauses），引导名词性从句的词叫连词。名词性从句又分别称为: 主语从句、宾语从句、表语从句、同位语从句 主语从句：是在复合句中充当主语的从句，常放在谓语动词之前或者用形式主语it代替，将其本身放在句尾。 例如：1. That he came here just now has been proved. 他刚才来的这里得到了证实。 解析：That he came here just now在谓语has been proved的前面，所以是主语从句。 2. It’s true that we are going next week. 我们下星期走是真的。 解析：真正的主语是 that we are going next week，前面的it是形式主语。 宾语从句：在复合句中作宾语的名词性从句，通常放在主句谓语动词（及物动词）和介词之后。 例如：1. We all know what he is. 我们都知道他是干什么的。 解析：what he is作及物动词know的宾语从句。 2. His worry is about whether he can succeed. 他的担忧是关于他是否能成功。 解析：whether he can succeed作介词about的宾语从句。 表语从句：在复合句中作表语的名词性从句，放在系动词之后，一般结构是：主语+联系动词+表语从句 例如：1. His question is where he can buy a house. 他的问题是他能在哪里买房子。 解析：where he can buy a house是联系动词is后面的表语从句。 2. This is why we can’t get their support. 这就是我们得不到他们支持的原因。 解析:why we can’t get their support是联系动词is后面的表语从句。 同位语从句：是用以说明所修饰名词的具体内容的，它与被修饰的词语通常可以划等号。例如：We heard the news that our team had won. 我听说了我们球队获胜的消息。
名词性从句 名词性从句相当于名词，可分别作主句的主语、表语、宾语和同位语。因此，名词性从句厅分为主语从句、表语从句、宾语从句和同位从句。 （一）引导名词性从句的连接词 1、连接代词：who, whose, whom, what, which。有词义，在从句中担任成分，如主语、表语、宾语、或定语等。 2、连接副词：when, where, why, how。有词义，在从句中担任成分，作状语。 3、连接词：that, whether, if, as if。that 无词义，在从句中不担任成分，有时可省略；if (whether), as if虽有词义，但在从句中不担任成分。 注意： 1、连接代词与连接副词在句中不再是疑问句，因而从句中谓语不用疑问式。连接代词与连接副词在从句充当句子成分，连接词whether 和if（是否），as if（好象）在从句中不充当句子成分，只起连接作用。根据句义，如果连接代词与连接副词，whether、if 和as if都用不上时，才用that作连接词（that本身无任何含义）。 2、不可省略的连词： （1）介词后的连词 （2）引导主语从句和同位语从句的连词不可省略。 That she was chosen made us very happy. We heard the news that our team had won. （二）主语从句 1、主语从句在复合句作主语。 e.g. Who will go is not important. 2、用it作形式主语，主语从句放在句末。 e.g. It doesn’t matter so much whether you will come or not. 主要句型有： （1）It+be+形容词+that从句。 It is probable that he told her everything. 很可能他把一切都告诉她了。 （2）It+be+名词词组(no wonder, an honour, a good thing, a pity, no surprise, etc.)+that从句。It’s no surprise that our team should have won the game. 我们没赢这场比赛真意外。 （3）It+be+过去分词+that从句。 It is said that Mr. Green has arrived in Beijing. 据说格林先生已经到了北京。 （4）It+seem, happen等不及物动词及短语+that从句。 It seems that Alice is not coming to the party at all. Alice似乎不来参加晚会。 （5）It+doesn’t matter (makes no difference, etc.)+连接代词或连接副词引起的主语从句。 It doesn’t matter whether she will come or not. 她是否来这无关紧要。 It makes no difference where we shall have the meeting. 我们在哪里开会毫无区别。 3、that引导主语从句时，不能省略。 e.g. That he suddenly fell ill last week made us surprised. 4、当主语从句作主语时，谓语动词一般用第三人称单数，下面这个句型例外。 What we need is more time and money. What we need are many more books. 5、if不能用在主语从句中，而是用whether Whether he left (or not) is unknown 6、引导主语从句的关联词有三类： (1)从属连词that。
名词性从句名词性从句引导词的基本用法：概念：（一）同宾语、名词性从句是指可以像名词一样在句子中充当主语、表语、了解各种引导词的使用首先要从整体上把握其基本形式，位语的从句。对于名词性从句， 同位语从句各自的一些特征。表语从句、宾语从句、方法。其次，要分别了解主语从句、（二）名词性从句的引导词 名词性从句的引导词引导词是否在名词性从句中充当成分的情况 连接代词：what, which, who, whom, whose 连接副词：when, where, why, how, what, which在从句中作主语、宾语、表语或定语； who在从句中作主语、表语；whom在从句中作宾语；whose在从句中作定语；when, where, why, how在从句中分别作时间状语、地点状语、原因状语、方式状语 连词: that;whether, if否 名词性从句的引导词： 1. 引导特殊疑问句的疑问词在转为引导名词性从句时，即成为连接代词(主要包括what, which, who, whom, whose)或者连接副词(主要包括when, where, why, how)。 注意体会如下例句：Choose which you like best. 选你最喜欢的。 // Who has taken away my bag is unknown. 谁拿走了我的包还不知道。 // Have you decided whom you are to nominate as your candidate? 你们是否已经决定提名谁做候选人了?/ / He asked when Mr. Gilbert would be allowed to go home. 他问什么时候可以允许吉尔伯特先生回家。 // Where we can look up his address is still a problem. 我们在哪儿可以查到他的地址还是个难题。// Why he did that wasn't quite clear. 他为什么做那件事还不十分清楚。 // How they will solve the serious problem has not been decided. 他们将怎样解决这个严重问题还没有决定。 以下两种特殊情况要给予特别关注： 也可以的问题，”？……什么“作连接代词引导的名词性从句既可以表示一个问what(1)． 表示相当于“名词/代词＋关系代词引导的定语从句”结构的意思，这种特殊用法在语法上被称作“关系代词型的what”，注意体会如下例句： He is not what (=the person that) he was a few years ago. 他不是几年前的他了。 // This is what (=the place that) they call Salt Lake City. 这就是他们称作盐湖城的地方。 // What (=the place that) is now the North Sahara Desert was once a civilized world. 现在的北部撒哈拉沙漠曾是一个文明世界。 // Our income is now double what (=the income that) it was ten years ago. 我们现在的收入是十年前的两倍。 // The color of the flower is different from what (=the color that) it was in the morning. 花朵(现在的)颜色与它早上的颜色不同。 (2) 带'ever后缀的疑问词除引导让步状语从句之外，还可以引导名词性从句(“no matter＋疑问词”的结构只能引导让步状语从句，不可以引导名词性从句)，注意体会以下例句：Whoever wants to see this film can go with us tonight.无论谁想看这部电影，今晚都可以和我们一起去。
