广泛存在于阅读理解，完形填空和写作中
考情分析：
名词性从句在高考中显性考查以语法填空补全句子形式出现。天津卷会涉及到选择题。名词性从句更
以隐性考查广泛存在于阅读理解长难句和应用文写作中。
1.考查名词性从句that 和what 的用法区别，这是高频考点也是难点。
2.考查名词性从句if 和whether 的用法区别。
3.考查名词性从句who, whoever, why, where, how 的用法区别。
4.遇到名词性从句需要学会用括号法括起来视为一个整体便于理解。
5.应用文写作和读后续写学会使用名词性从句能够提高句子表达力，提升文章档次。
复习目标：
1. 熟练掌握名词性从句连接词
、连接代词及连接副词
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。
考点 表语从句的构成及引导词
知识点1 表语从句构成
表语从句：在复合句中作表语的句子叫做表语从句。
The order is that
the
work
should
be
started
at once.
主语 谓语 表语从句
知识点2 表语从句的引导词
引导表语从句的连接词有三类：
连词that、whether，because, as if/though
疑问代词who, what, which，whom, whose, whatever, whoever, whomever, whichever;
疑问副词when, where, how, why，however, whenever, wherever 等
（1）连接词that 在表语从句中不充当任何的句子成分。
that 在引导表语从句时无词义。
例1. The trouble is (that) she has lost his money. 麻烦的事是他丢了钱。
例2. The question is whether we need more ice cream.
问题是我们是否还需要一些冰淇淋。
例3. 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。
例4. My opinion is that we should cultivate our children’s imagination.
我的看法是我们应该培养孩子们的想象力。
例5. The fact is that computers are of great aid to the development of science and technology.
事实是计算机十分有利于科学技术的发展。
（2）连接词whether 起连接作用，有词汇意义“是否”，不做成分，引导表语从句时不能省略。
whether 有词义，意为、“是否”。这时主句的主语常常是些抽象名词，如question(问题)，trouble(麻
烦)，problem(问题)，result(结果)，chance(可能性)，suggestion(建议)，idea(想法)，reason(理由)等。引导
表语从句时用whether 不用if。
例1. The question remains whether they will be able to help us. 问题还是他们能否帮我们。
例2. The question is whether a person can be trained to resist temptation.
现在的问题是，能否训练出抗拒诱惑的能力。
例3. The question now is whether these tigers have the capacity to adapt to those changes.
现在的问题是这些老虎是否有能力适应这些变化。
（3）连接代词-who/what/which/whom/whose/whatever/whoever/whomever/whichever 起连接作用，提示从
句开始。有词汇意义，不能省略。在表语从句中作主语、宾语、表语、定语。
例1.The problem is not who will go, but who will stay. 问题不是谁去，而是谁留下。
例2. Fame and personal gain is what they’re after. 他们追求的是名利。这是我们应该做的事情。
例4. This is what I am interested in. 这就是我感兴趣的东西。
例5. The doubt is who has got away with the document.问题是到底是谁偷走了这份文件。
（4）连接副词when, where, how, why，whenever, however, wherever 等在从句中充当时间状语、地点状
语、方式状语、原因状语 起连接作用，提示从句开始。有词汇意义，不能省略。
例1. My doubt is when we can finish our work. 我的是我们什么时候能完成工作。
例2. Home is where you can find love and care.家是你能找到爱和关怀的地方。
例3.The problem is how we can find him. 问题是我们如何找到他。火车站是火车停靠的地方。
例4.The train station is where the train stops.这就是我选择你的原因。
例5.This is why I chose you. 问题在于人们怎样才能找到一种有效的方式来储藏太阳热。
例6.The problem is how people can find an effective way to store the solar heat.
问题是人们如何找到一种有效的方法来储存太阳能。
知识点3 表语从句三大易混句式
1. 主语为名词reason 时，表语从句的引导词要用that， 一般不用why 或because。

知识点4 表语从句中的虚拟语气
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。当as/though 引导的表语从句时，从句动作可根据动作发生的真实情况与否用虚拟语气或真实语气。
例1. It seems as if someone is baking a cake.
闻起来好像是有人在烤蛋糕。（根据气味推断，很可能真的有人在烤）

例5. It sounds as if someone is knocking at the door. 听上去好像有人在敲门。
例6. 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
2. 主句主语是advice, suggestion, order, request, requirement 等名词时，表语从句的谓语动词常用
“(should)+动词原形”形式。
例1. My suggestion is that we (should) have a discussion about this matter instead of just laying it aside.
我的建议就是我们应当讨论一下这个问题，而不是把它放在一边。
例2. The captain’s order was that we (should) start out immediately it got dawn.
