专题 13 名词性从句
（解析版）
三年真题
1. 【2021·新高考I卷】______is so breathtaking about the experience is the out-of-this-world scenes.
1. What
【解析】考查主语从句。句意：这次经历的惊人之处在于这世界之外的景色。此处是主语从句，从句缺乏
主语，应用what引导，指代“经历的事情”。故填What。
2. 【2021·天津】What puzzles Lily's friends is ________ she always has so many crazy ideas.
A．whether B．why C．what D．when
2. B
【解析】考查连接词词义辨析。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。
3. 【2021·天津】It seemed that I had become ________ my parents had wanted me to be.
A．when B．where C．what D．whether
3. C
【解析】考查宾语从句。句意：似乎我已经成为了我父母希望我成为的人。动词 become后面是宾语从句，
从句缺少引导词，且从句中的be缺少表语，所填词应该起双重作用。故选C。
4. 【2021·浙江】Cobb, for her party, started to ask conference organizers who invited her to speak
_____ she could do so remotely
4. whether##if
【解析】考查宾语从句。句意：对于她的出席，Cobb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。
5. 【2021·北京】The poor woman wasn't able to give him any information about _______ she lived．
5. where
【解析】考查宾语从句。句意：这个可怜的老妇人不能说清楚她住在哪里。介词about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。6. 【2020·江苏】It is not a problem _____ we can win the battle; it’s just a matter of time.
A．whether B．why C．whenD．where
6. A
【解析】考查主语从句。句意:我们能否打赢这场战斗不是问题；这只是时间问题。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 of 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。
7. 【2020·天津】The student completed this experiment to make come true ______ Professor Joseph had
said.
A．that B．what C．whenD．where
7. B
【解析】考查名词性从句。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。
_________ Professor Joseph 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。
8. 【2020·浙江】Over thousands of years，they began to depend less on ______ could be hunted or
gathered from the wild，and more on animals they had raised and crops they had sown.
8. what
【解析】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。
9. 【2020·天津】My grandmother helped me believe that I could accomplish ____________ I put my
mind to.
A．whenever B．whatever C．wherever D．whichever
9. B
【解析】考查宾语从句。句意：我的祖母让我相信，我可以完成任何我专心去做的事情。A. whenever无
论何时；B. whatever 无论什么，任何；C. wherever无论何地；D. whichever无论哪一个。分析句子可知，
此处是宾语从句连接词，从句缺少宾语，应用连接代词，再结合句意，此处用“任何”符合语境，故选 B
项。

考点清单
一、名词性从句的概念及种类
在句中起名词作用的句子叫名词性从句。名词性从句的功能相当于名词词组，它在复合句中能担任主
语、宾语、表语、同位语。因此名词性从句分为主语从句、宾语从句、表语从句、同位语从句。
二、名词性从句的引导词
引导词 用法
连词 that、if/whether、as if、because 只起连接作用，不在从句中作任何成分。
连接代词 which、what、who、whom、whose 在从句中作主语、宾语、表语或定语等。
连接副词 when、where、why、how 在从句中分别作时间、地点、原因、方式状语。

同位语从 hope, idea, information, news, company when the manager is away.
句 problem, possibility,promise,
suggestion, truth等
四、that和what的区别
引导词 区别 例句
在从句中不作任何成分，只起连接 That she is a rich woman is known to us.
that
作用，没有词汇意义
在从句中充当句子成分，表示一定 What the teacher said has a good effect on the
what
的意义 children.
五、whether和if的用法
引导词 情况 例句引导位于句首的主语从句、表语从句和 The question is whether we should go on with
同位语从句时 the work.
从句作介词或discuss等的宾语时 It depends on whether it will be fine.
与or not直接连用时 I don’t know whether or not he arrives.
只用
whether It makes no difference whether he comes or
与表示选择的or...连用
leaves.
不用if
He asked me whether I’d move to New York
句子中已有if引导的条件句时
if I got the job.
用if容易发生歧义时 Please let me know whether you need help.
引导为了强调而置于句首的宾语从句时 Whether he will come I am not sure.
只用if
宾语从句为否定句 I don’t care if he doesn’t come.
不用
whether
宾语从句中不含or(not) he didn’t tell me whether/if he would come.

六、that引导的同位语从句和定语从句的区别
从句 例句 区别

同位语从句

The news (that) we heard on the 对先行词起修饰限制的作用；从句中缺成分
定语从句

动词doubt
否定形式 使用that引导宾语从句 I don’t doubt that you are honest.
