2. 命题规律及备考策略
【命题规律】近3年新高考卷对于名词性从句的考查共计6次，主要考查：
1．名词性从句连接词辨析；
2．名词性从句固定句型；
3. 名词性从句和定语从句的区别。
【备考策略】
1. 熟练掌握名词性从句连接词的用法和意义，特别是what和that的用法。
2. 熟练掌握名词性从句的固定句式和相关考点。
3. 理解名词性从句与定语从句的区别。
【命题预测】
预测2025年高考考查点：1.主要集中在名词性从句上的连接词；
2. 仍然有可能考查名词性从句固定句型，如表语从句，it作形式主语和形式宾语。
必备基础知识：
名词性从句的功能相当于名词词组,在复合句中担当主语、宾语、表语和同位语。按其句法功能可分为主语
从句、宾语从句、表语从句和同位语从句。引导名词性从句的连接词主要有以下几类:
宾语从句 主语从句 表语从 同位语

01 宾语从句
1）宾语从句主要跟在动词、介词和某些形容词之后。
知识1 动词后接宾语从句的用法
I wish hat he would understand me. 我希望他能理解我。
Whether we can succeed depends on how well we cooperate.我们能否成功取决于我们合作得怎么样。
知识2 介词后接宾语从句的用法
一般情况下介词后只能接wh-类连接词引导的宾语从句。
►He'll talk to us about what happened in the classroom.他将给我们讲述教室里发生的事情。
知识3 形容词后接宾语从句的用法
表示情感或态度的形容词后可接宾语从句。
常见的这类词有:afraid, certain, glad, pleased, sure, surprised, sorry, happy等。
►I' m very glad/pleased that all of your family will come.我很高兴你们全家都会来。
特别提醒 be sure后接宾语从句时连接词的选择:
1.be sure(用于肯定句或疑问句)+that从句。
►Are you sure that we' ll have a picnic this weekend?你确定我们本周末举行野餐吗?
2.be sure(用于否定句)+whether/if从句。
►I am not sure whether I should write to him or not.我不确定应不应该给他写信。
2）引导宾语从句的连接词主要有：
连接词：that，whether，if等
连接代词：what，who，whose，whatever，whichever，whoever等
连接副词：when，where，why，how等
1. 连接词that，whether，if引导
I think (that) you should turn to the teacher for help. 我认为你应该向老师寻求帮助。
I don’t know if/whether he still lives here after so many years. 我不知道这么多年后他是否还住在这儿。
注意：
whether/if 都意为＂是否＂。一般情况下，它们可以互换，口语中常用 if，但以下情况中，只能用
whether。
（1）与or not紧接连用时。
Let me know whether or not you can come. 请让我知道你是否能来。（2）作介词的宾语从句时。
We are interested in whether you will attend the meeting. 我们对你是否参加会议感兴趣。
2. 连接代词what，who，whose，whatever，whichever，whoever等引导
She asked me whose handwriting was the best in the class. 她问我班上谁的书法最好。
I’ll just say whatever comes into my mind. 我想到什么就说什么。
3. 连接副词when，where，why，how等引导
Do you know when the ancient Olympic Games began? 你知道古代的奥运会是什么时间开始的吗?
I’ve been thinking about how we can make the newspaper more interesting. 我一直在考虑如何使我们的报
纸更用趣。
3). 宾语从句的语序
在宾语从句中要用陈述句语序。
He asked me when we could set out the next day. 他问我第二天什么时候可以出发。
Did you find out where she lost her car? 你查出她在哪里丢的车了吗?
4). 宾语从句的时态
（1）当主句的谓语动词是一般现在时时，其宾语从句的时态可以是任何适当的时态。
She says (that) she works from Monday to Friday. 她说她周一至周五上班。(从句是一般现在时)
she says (that) she will leave a message on his desk. 她说她要在他桌子上留个便条。(从句是一般将来时)
She says (that) she has never been to Mount Emei. 她说她从来没有去过峨眉山。(从句是现在完成时)
（2）当主句的谓语动词是一般过去时时，其宾语从句的时态一般要用适当的过去时态。
He said there were no classes yesterday afternoon. 他说昨天下午没有课。(从句是一般过去时)
He said that he was going to take care of the baby. 他说他会去照看这个婴儿。(从句是过去将来时)
He said that they were having a meeting at that time. 他说他们那时正在开会。(从句是过去进行时)
（3）当宾语从句是表达客观真理和规律的句子时，其时态仍旧用一般现在时。
The teacher told us that nothing is difficult if we put our hearts into it. 老师告诉我们世上无难事，只怕有
心人。
He said that light travels much faster than sound. 他说光比声音传播得快。
5). 动词后宾语从句的特殊用法
①动词find，feel，think，consider，make，believe，guess，suppose，assume等后有宾语补足语时，则
需要用it作形式宾语，而将that宾语从句后置。
I think it necessary that we take plenty of boiled water every day. 我认为每天多喝开水是有必要的。
I have made it a rule that I keep diaries. 我每天写日记成了惯例。
②hate，like，take，owe，have，take for granted等表示＂喜欢；痛恨；认为＂的动词或动词短语和see
to表示＂注意，留意＂后有宾语补足语时，需要用it作形式宾语而将宾语从句后置。
I hate it when they talk with their mouth full of food. 我讨厌他们满嘴食物说话。
When you start the engine, you must see to it that the car is in neutral. 启动发动机时，一定要使汽车的离
合器处于空档位置。③介词后的宾语从句。
She is always thinking of how she can do more for others. 她总想着如何才能为别人做得更多。
We are talking about whether we admit students into our club.
我们正在讨论是否让学生加入我们的俱乐部。
④宾语从句的否定转移。将think，believe，suppose，expect，fancy，imagine等动词后面宾语从句的
否定词转移到主句中，即主句的谓语动词用否定式，而从句的谓语动词用肯定式。
I don’t think I know you. 我想我并不认识你。
I don’t believe he will come. 我相信他不会来。
doubt+宾语从句
►I don't doubt that the plan is practical, but I doubt whether/if he can stick with the plan until it's finished.我不怀
疑这个计划的可行性,但是我怀疑他能否坚持执行下去,直到计划完成。
宾语从句的用法速记口诀
宾语从句须注意，几点事项应牢记。
一是关键引导词，不同句子词相异。
陈述句子用that；一般疑问是否（if，whether）替；
特殊问句更好办，引导还用疑问词。
二是时态常变化，主句不同从句异。
主句若为现在时，从句时态应看意；
主句若为过去时，从句时态向前移。
三是语序要记清，从句永保陈述序。
【2024全国甲卷】How did the national park system come about? On a cool, starry night in mid-September 1870,
four men relaxed before a campfire along the Firehole River in ____43____ is now northwestern Wyoming.
【2024届江苏省南通市高三下学期四模】While 28traditional (tradition) shadow play often involves
fancy handmade puppets and fascinating storytelling, contemporary artists have explored new techniques, pushingthe boundaries of 29 is possible with shadow play. Despite the rise of digital entertainment, shadow play, a
timeless tradition that goes beyond borders and generations, continues to exist 30 as a valuable art
form in many parts of the world.
02主语从句
1.主语从句在复合句中充当主语，大多数主语从句都可以用it作形式主语而把主语从句置于句尾。
2.that引导主语从句时可用it作形式主语，that不可省；what引导的主语从句表示＂……的东西＂时，一般
不用it作形式主语；whatever，whoever，whichever一般也不用it作形式主语。
☞That she will succeed is certain.
☞It is certain that she will succeed.
常见的it替代that引导的主语从句的句式主要有以下几种：
(1)It＋系动词＋形容词(necessary，right，likely，unlikely，wrong，important，certain，clear，obvious，
strange，normal等)＋that从句
☞It is certain that most of the farmers have brought in more money by all means.
(2)It＋be＋名词(短语)(a pity，a shame，good news，a fact，an honour，a wonder，no wonder等)＋that从句
It’s no wonder that you’ve achieved so much success.
(3)It＋be＋过去分词(said，told，heard，reported，decided，suggested，advised，ordered，remembered，
thought，considered，wellknown，announced等)＋that从句
☞It is said that the professor has already succeeded in carrying out the experiment.
(4)It＋特殊动词(seem，appear，happen，matter)＋that从句
☞It happened to me that I had been away when he called.
注意：(1)在＂It is necessary/important/strange/natural...＋that从句＂结构中，从句谓语常用＂(should＋)
动词原形＂形式。
【拓展延伸】主语从句的引导词
引导词 作用 引导词 作用
that 无词义，在从句中不充当成分，但不能省略 how 多么，怎样，作方式状语或程度状语
who 谁，作主语、宾语 when 何时，作时间状语
whom 谁，作宾语 where 在哪儿，作地点状语
what 什么，可作主语、宾语、表语、定语 why 为什么，作原因状语
which 哪一个，哪些，作主语、宾语、定语 whether 是否
【特别注意】当作主语的句子太长时，为保持句子平衡，常用it作形式主语，而将真正的主语置后。if＂
是否＂，不可直接引导主语从句(用it作形式主语时可以) 。
3. 主语从句的特殊用法
（1）主语从句与定语从句的转换☞What is needed has been bought.
☞All that is needed has been bought.
所有需要的都被买了。
（2）几个特殊句型之间的转换
☞It is known to all that China has joined the WTO.
As is known to all, China has joined the WTO.
What is known to all is that China has joined the WTO.众所周知，中国已加入WTO。
4. 从句作主语时，句子谓语动词的单复数问题
(1)从句作主语时，谓语动词一般用单数。
That they are not going to the cinema is a big surprise to us.他们不去看电影，这使我们感到很惊讶。
(2)what引导的从向作主语，谓语动词一般用单数;若从句谓语或从句后的表语是复数形式,则谓语动词常用
复数。
What she said is wrong.她所说的是错误的。
What we need are books.我们所需要的是书籍。
【2021.6新高考1卷】Going to Mount Huangshan reminds me of the popular Beatle's song "The Long and
Winding Road". 1 is so breathtaking about the experience is the out-of-this-world scenes.
Li is not without criticism. Some people have expressed skepticism because it is unbelievable ______ she looks so
perfect after a long day of work in the fields.
03 表语从句和同位语从句
一、表语从句
引导表语从句的连接词主要有：
连接词：that，whether
连接代词：who，whom，whose，which，what，whoever whomever，whichever，whatever
连接副词：when，where，how，why
1. 连接词引导
☞The reason for his absence is that he hasn’t been informed. 他缺席的原因就是他没接到通知。
☞The question remains whether they will be able to help us. 问题还是他们能否帮我们。
2. 连接代词和连接副词引导
☞The problem is who will take charge of this shop. 问题是谁将接管这家店铺。
☞That is when I realized the importance of journalism. 那时我才意识到新闻工作的重要性。
注意：
（1）as/as if/as though 引导的表语从句常跟在特定动词后面，如 seem，appear，look，taste，sound，feel等。
☞It sounds as if someone is knocking at the door. 听上去好像有人在敲门。
☞At that time, it seemed as though I couldn’t think of the right word. 当时我似乎怎么也想不出一
个恰当的字眼来。
（2）当主句的主语是reason时，表语从句一般由that引导，这种用法常见于句型The reason why... is
that...
☞The reason why he came late was that he got up late. 他来得晚是因为起床晚了。
2表语从句的三个易混句式
句式 用法 例句
This/'That is why+结果 意为"这那就是.....to work there. 那 That's why I want you to work there.
就是的原因"，why 引导表语从 我想要你在那儿工作的原因。
句。
This/That/It is because 意为"这/那是因为.....，because引 It's just because he |doesn't know her.
+原因 导表语从句。 这
这仅仅是因为他不认识她 。
The reason why... is 意为"......的原因是……”， The reason why he didn't come was
that it was raining heavily.他没有来的
that... why定语从句，修饰先行词reason,
原因是 (当时)雨下得很大。
that引导表语从句。
二、同位语从句
知识1 同位语从句前名词的特殊性
同位语从句前的名词通常是fact, news, idea, truth, hope, problem, information, belief, thought, doubt, promise,
question等表示抽象意义的名词, 同位语从句用于对这些名词作进一步的解释或说明。
►She has to face up to the fact that she is no longer young.她必须正视自己不再年轻这一事实。
►The question whether he will join us is very important.他是否会加入我们这个问题很重要。
知识2 分割式同位语从句
有时主句的谓语较短,而同位语从句内容较长,为避免"头重脚轻",常常将谓语部分提到从句前面,形成分隔式
同位语从句。
►My wish will come true one day that I should buy a big house for my parents.我要给父母买一套大房子的愿望
总有一天会实现。
►Word came that our school had won first prize in the final.消息传来说,我们学校已经在决赛中获得了一等
奖。

natural way of life in line with their inner selves. They are 30 young people and traditional Chinese
culture blend (融合).
04名词性从句连接词的辨析
1）what 与that引导名词性从句的区别
that在从句中不充当句子成分,也没有含义;what在从句中可以作主语、表语、宾语和定语,意思是"什么,……
的事情,什么样的"。
►That he failed in the test again really puzzled us.他又一次没通过考试,这真让我们感到迷惑不解。(that在主
语从句中不作成分,不可以省略)
►These photographs will show you what our village looks like.这些照片将向你展示我们村的面貌。(what在宾
语从句中作介词like的宾语)
►We haven't decided what measures we should take to deal with the noise problem.我们还没有决定应该采取什
么措施来解决噪声问题。(what在宾语从句中作定语)
2）whether 与if
☞ (1)whether和if在宾语从句中可以互换，但是作介词宾语时连接词一般用whether。
It all depends on whether they will come back.
(2)后面直接跟or not 时用whether。
☞I didn’t know whether or not he had arrived in Wuhan.
(3)主语从句、表语从句中只能用whether。
☞Whether the meeting will be put off has not been decided yet.
☞The question is whether they have so much money.
(4)whether可以引导同位语从句，用以说明前面的名词的内容，if则不能。
☞We ought to discuss carefully the question whether we can do it or not.
(5)whether常与or连用表示一种选择，if不能这样用；whether也可与动词不定式连用但if不能。
☞The question of whether they are male or female is not important.
☞I have not decided whether to go or not.
(6)间接宾语位于句首时或者间接宾语提前时用whether不用if。
☞Thank you，but whether I’ll be free I’m not sure at the moment.
(7)whether可引导一个让步状语从句表示＂不管＂、＂无论＂，而if不能。
☞Whether he comes or not，we will begin our party on time.
3）.wh-与wh-ever引导名词性从句的区别
(1)疑问词＋ever可引导名词性从句，在主从句中要充当一定的成分。
☞Whoever breaks the rule must be punished.
☞You can choose whatever you like in the shop.
(2)疑问词＋ever还可引导让步状语从句。☞Whoever breaks the rule，he must be punished.
☞Whatever you do，you must do it well.
(3)no matter＋疑问词只能引导让步状语从句。
☞No matter what you do，you must put your heart into it.
☞No matter who comes late，he must be punished.
4）.when和where引导的同位语从句与定语从句的区别。
when 和where前面的名词若是表示时间、地点的名词，则when和where引导的是定语从句，否则则为同
位语从句。
☞They put forward the question where they could get the money.(同位语从句)
☞This is the place where the accident happened.(定语从句)
