核心考向聚焦
核心价值：掌握三大从句与特殊句式的结构与用法，提升语言表达的准确性与复杂
性，增强阅读理解与书面表达能力。
关键能力与思维瓶颈
关键能力： 本专题重点考查从句引导词的辨析与选用、句子结构的分析与转换、
特殊句式的识别与应用。
培优瓶颈： 学生易混淆从句类型（如定语从句 vs 同位语从句）、误用连接词
（如 that/what）、忽略语序与时态呼应，以及在写作中未能灵活运用高级句式。
命题前瞻与备考策略
预测： 高考将继续围绕从句引导词的选择、句子结构的辨析（如定语从句与状语
从句）、特殊句式（倒装、省略、There be）的应用设题，注重在语篇中考查语法
综合运用能力。
策略：系统梳理各类从句与句式的结构特点，通过对比辨析强化易混点，结合真题
与变式训练提升语境判断与句式升级能力。
◇考点 01 定语从句关系代词 which/that/who/whom 全解
1. 基本用法与指代规则
which：指代物，在从句中作主语/宾语（作宾语可省略）The book which was written by Mo Yan has been
translated into 30 languages.（作主语，不可省略）
The book (which) I bought yesterday is very interesting.（作宾语，可省略）
that：指代人/物，在从句中作主语/宾语/表语（作宾语可省略）This is the best film that I have ever seen.
（指代物，先行词被最高级修饰）
He is the man that helped me yesterday.（指代人）
who/whom：指代人，who 作主语/宾语，whom 仅作宾语（作宾语可省略）The girl who is standing there is
my sister.（作主语）
The professor (whom) we met yesterday will give us a lecture.（作宾语）
2. that vs which
考
考点
关键区别（高
高频
）
只能用that 的情况 只能用which 的情况
先行词被序数词
①
/最高级修饰
②先行词是all, everything, nothing 等不定代词
③先行词既有人又有物
④先行词被the only, the very 修饰
引导非限制性定语从句
①
"
②介词+关系代词"结构中
③先行词是that/those 时
④引导修饰整个主句的定语从句
错误：This is the museum where we visited last week.
正确：This is the museum that/which we visited last week.
（解析：visit 是及物动词，需要宾语，where 是关系副词不能作宾语）
【高分技巧】
在书面表达中，将简单句升级为定语从句可提升语法复杂度。如：
基础版：Our school has a library. It was built in 1980.
升级版：Our school has a library which was built in 1980.（限制性定语从句）
高级版：Our school has a library, which was built in 1980 and now has over 100,000 books.（非限制性定语
从句，增加信息量）
◇考点 02 "介词＋关系代词"引导的定语从句
1.
三
介词选择
大依据
与先行词搭配：根据先行词的习惯搭配确定介词I still remember the day on which I joined the Party.（the
day 与on 搭配）
This is the company in which my father works.（the company 与in 搭配）
与从句动词搭配：根据定语从句中谓语动词的固定搭配确定介词He is the man with whom I worked closely.
（work with sb. 与某人合作）
This is the problem about which we talked yesterday.（talk about sth. 谈论某事）
根据句意逻辑：根据上下文语义确定介词The temperature at which water boils is 100℃.（表示"在
温度
……
下"）
He has three sons, two of whom are doctors.（表示"其中的"）
2.
考
高频介词搭配清单（高
必备）
on which = when（具体日期/星期）
in which = when（年/月/季节/世纪）
by which time（到那时为止）
during which（在
期间）
……
"介词提前看搭配，动词先行和语义；
关系代词指人whom，指物which 要记准；
固定搭配需牢记，高考真题常考及。"
◇考点 03 关系副词 when/where/why 到底用不用？
1. 基本用法与判断标准
关系副词在定语从句中作状语，替代先行词在从句中表示的时间、地点或原因。判断标准：先行词在从句
中是否作状语。
关系副词
用先行词类型
在从句中作
可替换结构
when
表示时间的名词（day, year, time 等）
时间状语
on/in/at which
where
表示地点的名词（place, city, room
等）
地点状语
in/at/on which
why
reason
原因状语
for which
2.
点
析
易混
辨
：关系副词vs 关系代词
This is the factory
①
where my father works.（正确，work 是不及物动词，从句主谓完整，缺地点状语）
This is the factory
②
which we visited last week.（正确，visit 是及物动词，从句缺宾语）
I'll never forget the day
③
when I met you.（正确，met 虽及物，但已有宾语you，缺时间状语）
I'll never forget the day
④
(which) we spent together.（正确，spent 缺宾语）
3. 特殊先行词后的where
考
点
（高
热
）
某些抽象名词后可用where 引导定语从句，表示"在
方面
……
/情况下"：
case, situation, condition（情况）
point, stage（阶段）
activity, event（活动）
position, role（位置/角色）
We have reached a point where we must make a decision.（我们已到了必须做决定的阶段）
He's in a situation where he has to choose between job and family.（他处于必须在工作和家庭间做选择的境
地）
将先行词放入定语从句，若需要加介词才能使从句完整，则用关系副词或"介词+关系代词"；若不需要加介
词直接作成分，则用关系代词。
例：I like the house. I was born in the house. → I like the house where/in which I was born.（需要加介词in，
用where）
◇考点 04 名词性从句（主/宾/表/同）核心用法
1. 四大名词性从句基本结构
从句类型
位置特征
常用连接词
例句
主语从句
句首或it 作形式主语
后
that, whether, what, who 等
What he said surprised us all. / It's
clear that he will win.
宾语从句
及物动词/介词后
that(可省), if, whether, what
等
I think (that) he is right. / I'm
interested in what she said.
表语从句
系动词后
that, whether, what, because
等
The fact is that he lied. / This is why
we came late.
同位语从句
抽象名词后，解释名
词内容
that, whether, how 等
The news
that he won
excited
everyone. / I have no idea whether he
will come.
2.
考
点
语序规则：陈述语序（高
易错
）
所有名词性从句都必须用陈述语序（主语在前，谓语在后），即使从句表达疑问含义。
错误：I don't know what is his name.（疑问语序）
正确：I don't know what his name is.（陈述语序）
错误：Can you tell me how can I get there?
正确：Can you tell me how I can get there?
3. 时态呼应规则
主句为现在/将来时态，从句可根据实际情况用任何时态
主句为过去时态，从句通常用相应的过去时态（客观真理除外）
He says he will go to Beijing tomorrow.（主句现在时，从句将来时）
He said he would go to Beijing the next day.（主句过去时，从句过去将来时）
The teacher told us the earth goes around the sun.（客观真理，用一般现在时）
【高分写作应用】：在书面表达中灵活运用名词性从句可提升句式复杂度。如表达观点时：
基础版：We should protect the environment. This is important.
升级版：That we should protect the environment is important.（主语从句）
高级版：It's important that we should protect the environment, which is beneficial to our health.（形式主语
+非限制性定语从句）
◇考点 05 名词性从句连接词 that/what/whether/if 深度抉择
1. that vs what："无义连接"与"有义连接"
根本区别：that 在从句中不充当成分，无实际意义；what 在从句中充当主语/宾语/表语，有"所
的
……
"含
义。
① That he will come is certain.（that 不充当成分，无意义，引导主语从句）
② What he will say is uncertain.（what 作say 的宾语，表示"他所说的话"，引导主语从句）
The fact is
③
that he lied.（that 不充当成分，引导表语从句）
The fact is
④
what we need to know.（what 作know 的宾语，引导表语从句）
2. whether vs if："是否"的选择困境
两者都可表示"是否"，但以下情况只能用whether：
引导主语从句（置于句首时）
引导表语从句和同位语从句
与or not 直接连用
作介词宾语
后接动词不定式
Whether he will come is unknown.（主语从句，不能用if）
The question is whether we should go.（表语从句，不能用if）
I have no idea whether he will come or not.（同位语从句+or not，不能用if）
It depends on whether he can arrive on time.（介词on 后，不能用if）
He doesn't know whether to stay or leave.（后接不定式，不能用if）
3. 连接代词与连接副词的选择
根据从句缺少的成分类型选择：
缺主语/宾语/表语/定语 用连接代词（
→
what, who, whom, whose, which）
缺状语（时间/地点/原因/方式等） 用连接副词（
→
when, where, why, how）
I don't know who broke the window.（缺主语，指人
→who）
I don't know what he wants.（缺宾语，指物
→what）
I don't know whose book this is.（缺定语
→whose）
I don't know when he will come.（缺时间状语
→when）
I don't know how he did it.（缺方式状语
→how）

They are having almost as much unemployment as we are.
◇考点 07 定语从句与状语从句的边界区分
1. 根本区别：修饰对象不同
定语从句：修饰名词或代词，相当于形容词作用
状语从句：修饰动词、形容词、副词或整个句子，表示时间、地点、原因、条件等
2.
深
析
易混引导词
度辨
（1）where 引导的定语从句 vs 地点状语从句
类型 特点 例句 判断方法 定语从句 前面有先行词（地点名词） I visited the factory where my father
works. 可还原为"in the factory"（有先行词factory） 地点状语从句 前面无先行词，直接修饰动词Where
there is a will, there is a way. 不可还原为"in the where"（无先行词）
（2）when 引导的定语从句 vs 时间状语从句
定语从句：I still remember the day when I first met you.（前面有先行词the day）
时间状语从句：When I met him, he was reading a book.（前面无先行词，修饰整个主句）
（3）as 引导的定语从句 vs 状语从句
定语从句（非限制性）：As we all know, the earth is round.（as 指代整个主句内容，可译为"正如"）
时间状语从句：As I was walking, I met an old friend.（译为"当
时
……
"，主从句动作同时进行）
让步状语从句：As tired as he was, he continued working.（译为"尽管"，用于倒装结构）
三步区分法（高考解题必备）
1. 找先行词：从句前是否有被修饰的名词/代词？有 可能是定语从句
→
2. 分析功能：从句是修饰名词还是修饰动词/整个句子？修饰名词 定语从句
→
3. 替换验证：能否用"介词+关系代词"替换引导词？能 定语从句；不能 状语从句
→
→
◇考点 08 完全倒装与部分倒装（附高频倒装信号词清单）
1. 完全倒装：主谓宾结构完全颠倒
定义：将整个谓语动词提到主语之前，主要用于强调句首的状语。
常见情形：
表示方位的副词/介词短语置于句首（up, down, in, out, here, there, on the hill, under the tree 等） Out
rushed the children.（孩子们冲了出去）
On the top of the mountain stands a temple.（山顶上矗立着一座寺庙）
there be 句型（be 动词可替换为live, stand, lie, exist 等） There stands a tall building in front of our
school.（我们学校前面有一座高楼）
There lived an old man in the village.（村里住着一位老人）
2. 部分倒装：助动词/情态动词提到主语前
定义：仅将谓语的一部分（助动词、情态动词、be 动词）提到主语之前，主要用于强调或构成疑问句。
倒装类型
信号词/句型
例句
否定词提前
never, hardly, scarcely, seldom, rarely
Never have I seen such a beautiful place.
not until...
Not until he came back did I leave.
no sooner...than, hardly...when
No sooner had we arrived than it began to
rain.
in no way, by no means, at no time
In no way can we give up.
only+状语提前
only+副词/介词短语/状语从句
Only in this way can we solve the problem.
so/such 置句首
so+形容词/副词, such+名词 结构中
So fast did he run that I couldn't catch up.
as/though 引导
让步状语从句
形容词/副词/名词+as+主语+谓语
Young as he is, he knows a lot.
3.
情
不倒装的特殊
况
当句首状语是here, there, up, down 等，且主语是人称代词时不倒装Here he comes.（他来了）（主语是
代词he，不倒装）
only 修饰主语时不倒装Only he can solve the problem.（只有他能解决这个问题）
as 引导让步状语从句时，若提前的是名词，名词前不加冠词Child as he is, he knows a lot.（尽管他是个
孩子）（child 前不加a）
【高频再现】高频倒装信号词清单（高考必备）：
否定类：never, hardly, scarcely, seldom, rarely, not until, no sooner, hardly when, in no way
强调类：only+状语, so...that, such...that
让步类：as, though
方位类：here, there, up, down, in, out, away, on the hill
记忆口诀："否定副词放句首，only 状语在前端，so 和such 加that，as/though 引导让步，全部都要部分
倒；方位副词句首站，完全倒装记心间。"
◇考点 09 省略句的常见情形与判断
1.
考
考点
状语从句的省略（高
核心
）
条件：当状语从句的主语与主句主语一致，且从句谓语含be 动词时，可省略从句的主语和be 动词。
高频省略类型：
时间状语从句（when, while, as, once, until 等引导）When (I was) walking in the street, I met an old friend.
（省略主语I 和was）
While (he was) studying, he fell asleep.（省略主语he 和was）
条件状语从句（if, unless 等引导）If (it is) necessary, I will help you.（省略it is）
Unless (you are) invited, you shouldn't go.（省略you are）
让步状语从句（though, although, even if 等引导）Though (he was) tired, he continued working.（省略he
was）
Even if (I am) invited, I won't go.（省略I am）
方式状语从句（as if, as though 引导）He talks as if (he were) a expert.（省略he were）
2. 不定式省略（保留to）
当不定式在上下文重复出现时，可省略不定式后的动词，仅保留to。
He didn't come, though he had promised to.（=to come）
I want to go with you, but my mother doesn't allow me to.（=to go with you）
He didn't pass the exam, but he hoped to.（=to pass the exam）
3.
情
其他常见省略
形
对话中的省略（省略主语、谓语等）—Where are you going? —To the library.（=I am going to the library）
—Have you finished your homework? —Not yet.（=I haven't finished my homework yet）
there be 句型的省略（省略there be） Any news?（=Is there any news?）
Nobody in the room.（=There is nobody in the room.）
独立主格结构中的省略（省略being）The meeting (being) over, we left the room.（会议结束后，我们离开
了房间）
4. 省略句的判断与还原技巧
1. 找主语：判断从句主语是否与主句一致
2. 补全成分：尝试还原被省略的主语和be 动词
3. 验证逻辑：还原后句子是否通顺，逻辑是否合理
真题分析（2023 年全国卷短文改错）
原句：While walked in the park, I saw a bird.（错误）
分析：while 引导的时间状语从句，主语I 与主句主语一致，从句应省略I was，保留walking → 改为While
walking in the park, I saw a bird.
①当从句主语与主句主语不一致时，不可省略主语和be 动词
错误：While walking in the park, a bird was seen.（主语不一致，应改为While I was walking in the park, I saw
a bird.）
②感官动词和使役动词后的不定式省略to（see, hear, make, let 等）
例：I saw him enter the room.（不是to enter）
但被动语态中to 要还原：He was seen to enter the room.
◇考点 10 There be 句型的进阶用法
1.
一
基本结构与主谓
致
基本结构：There be + 主语 + 地点状语（表示"某地有某物"）
主谓一致规则：be 动词的单复数形式由最靠近be 的主语决定（就近原则）
There is a book and two pens on the desk.（靠近be 的主语a book 是单数，用is）
There are two pens and a book on the desk.（靠近be 的主语two pens 是复数，用are）
There is a lot of water in the bottle.（不可数名词，用is）
There are many students in the classroom.（可数名词复数，用are）
2. be 动词的灵活替换（高级表达）
为避免单调，be 动词可替换为表示"存在、发生、出现"的动词：
表示存在：live, exist, lie, stand, remain There lives an old man in the village.（村里住着一位老人）
There stands a tall building on the hill.（山上矗立着一座高楼）
There lies a river between the two villages.（两村之间有一条河）
表示发生/出现：happen, occur, appear, seem, come, go There happened an accident yesterday.（昨天发生
了一场事故）
There appears to be a mistake in the report.（报告中似乎有个错误）
There came a knock at the door.（传来一阵敲门声）
3.
化
时态变
与非谓语形式
（1）时态变化
一般现在时：There is a meeting every Monday.（每周一有会议）
一般过去时：There was a football match yesterday.（昨天有场足球赛）
一般将来时：There will be / There is going to be a party tomorrow.（明天有个派对）
现在完成时：There has been great changes in our city.（我们城市发生了巨大变化）
过去完成时：There had been no rain for three months.（已经三个月没下雨了）
（2）非谓语形式
不定式：there to be（作主语、宾语、表语）It's impossible for there to be another earthquake.（不可能
