什么是名词性从句
名词性从句中的连接词
1. that（不充当句子成分，无任何含义，引导宾语从句时可省略）
2. whether和if（不充当句子成分，表“是否”，多用whether）
3.特殊疑问词(who;whom;whose;what;which;when;where;why...充当成分，且有含义)
Why she didn't get the job is obvious.
she will get the job is still a question.
she didn’t get the job is a pity.
It’s a pity that she didn’t get the job .
从句都要用陈述语气！
她那么努力却没得到这份工作，真是遗憾。
她是否能得到这份工作是个问题。
她为什么没得到这份工作是很明显的。
That
will she get the job
Whether
Why didn't she get the job
易错点1. that和what的区别
His greatest achievement was
他最大的成就是他对医学研究的贡献。
His greatest achievement was ________ he contributed to medical research.
that he made great contributions to medical research.
what
that引导名词性从句时，不充当句子成分，无任何含义(引导宾语从句时通常可以省略)；
what引导名词性从句时，要充当一定的句子成分，意为“什么”或“所…的”。
易错点2. that引导的同位语从句与定语从句的异同
同位语从句
定语从句
Parents often cherish the hope that their children will surpass them.
父母常怀有孩子会超越自己的希望。
The hope that drives scientific research is finding cures for diseases.
推动科学研究的希望是找到疾病的治愈方法。
位置：
作用：
that：
名词后
同位语从句解释名词的含义或内容，说明前面的的名词是什么
定语从句只是对名词（先行词）的限定和修饰，译为：...的
同位语从句中，连接词that只起连接作用，不充当任何句子成分；
定语从句中的关系代词that不仅起连接作用，还在从句中充当成分
易错点3. “疑问词＋-ever”和“no matter＋疑问词”的区别
(1)“疑问词＋-ever”可引导名词性从句。
Whichever path you choose leads to new opportunities.
你选择的任何路径都会带来新机遇。
(2)“疑问句＋-ever”还可引导让步状语从句。
Whatever you say, I won’t change my mind.
无论你说什么，我不会改变主意。
(No matter what you say, I won’t change my mind.)
(3)“no matter＋疑问词”只能引导让步状语从句。
易错点4. 主语从句的核心考点
常见的it作形式主语的主语从句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, natural等)＋that从句
It is evident that climate change is accelerating because of the green house effect.
It is well known that even the same leisure activity may be used differently by different individuals.
(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 an honour that you invited me to speak here.
It is common knowledge that the Earth revolves around the Sun.
(3)It＋be＋过去分词(said, told, heard, reported, decided, suggested, advised, ordered, remembered, thought, considered, well-known, announced, requested, required, insisted等)＋that从句
It is said that tea can improve creative power of the literary artists in ancient China.
据说茶能提高古代中国文人的创造力。
It was reported that by the end of 2023, his business had expanded throughout the world.
据报道，到2023年底，他的业务已经扩展到了全世界。
(4)It＋特殊动词(seem, appear, happen, matter)＋that从句
It seemed that he knew the answer, yet he remained silent.
It happened that Mathilde met with Jeanne in the park in Paris after ten years.
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”。
It is necessary that all documents (should) be submitted by Friday.
It is important that students develop an awareness of how the Internet can be used.
(2)在“It＋be＋suggested / advised / ordered / requested / insisted / required...＋that从句”结构中，从句谓语应用“(should＋)动词原形”。
It is suggested that you (should) review the report carefully.
It is ordered that the company (should) cease operations until further notice.
主句的主语是idea, advice, suggestion, order, request, requirement等名词时，表语从句的谓语应用虚拟语气，即“(should＋)动词原形”的形式。
Their financial advice was that we (should) invest in real estate.
The committee’s suggestion was that the policy (should) be revised.
The new safety requirement was that all workers (should) wear helmets.
易错点5. 表语从句的核心考点
考向1　宾语从句中的连接词
单句语法填空
1. (2024年全国高考英语甲卷)On a cool, starry night in mid-September 1870, four men relaxed before a campfire along the Firehole River in ______ is now northwestern Wyoming.
【解析】考查宾语从句。句意：1870年9月中旬，在一个凉爽、繁星点点的夜晚，四个男人在火洞河边的营火前放松，这里现在是怀俄明州的西北部。后文为介词in的宾语，is前缺主语，指物，主语用what引导宾语从句，作介词in的宾语，故填what。
what
2. (2022·新课标全国卷II) “He saved my son’s life,” said Mrs. Brown. “I don’t know _____ to thank him.”
【解析】考查连接词。根据句子结构可知，设空处填写的是特殊疑问词+to do结构做宾语，相当于一个宾语从句，表示“我不知道如何感谢他”，故填how。
how
2.重温高考真题
1. (2025年高考英语北京卷)The truth, though, is _________ could be guessed — there’s never anyone else here. Just me, Nick, and the quiet forest.
【解析】考查表语从句引导词。句意：不过，真相正如所料 —— 这里从来没有其他人。be动词is后接表语从句，从句中缺少主语，指物，用what引导，且what在从句中作主语，意为“…… 的事情”。故填what。
what
考向2　表语从句中的连接词
单句语法填空
2. (2023·新课标全国卷II) They also need to be ready to give interviews in English with international journalists. This is ______ they need an English trainer.
【解析】考查连接词。句意：他们还需要准备好接受国际记者的英语采访。这就是为什么他们需要一个英语教练。所填词引导表语从句，说明他们需要英语教练的原因。故填why。
why
考向3　主语从句和同位语从句中的连接词
单句语法填空
1. (2021·全国卷I) ______ is so breathtaking about the experience is the out-of-this-world scenes.
【解析】考查主语从句。句意：这次经历中最令人激动的莫过于那些世外桃源的场景了。根据句子结构分析可知，这里是主语从句引导词，同时在从句中做主语。故填What。
2. （24-25高三·全国·单元测试） many places still are suffering food shortages remains a big concern.
【解析】考查主语从句。句意：许多地方仍然面临食品短缺，这仍然是一个大问题。分析可知设空处连接主语从句，从句中不缺少成分，引导词无意义，应用that连接，句首单词首字母大写，故填That。
What
That
Thank you
