2024届高考英语二轮复习：定语从句导学案(含答案)
2024届高考英语二轮复习：定语从句导学案（含答案）2024年高考英语一轮复习——定语从句导学案定语从句概述定语从句（Adjective Clause）是指在复合句中用来修饰一个名词或代词的从句。
这个从句通常由关系词引导，将句子中关系密切的内容用一个句子来表示。
1. 定语从句的引导词：引导定语从句的关系词包括关系代词和关系副词。
关系代词有：that、which、who、whom、whose。
关系副词有：where、when、why。
2. 关系词在定语从句中的作用：关系词在定语从句中充当一部分语法成分，并引导定语从句与主句之间的关系。
关系代词的作用有：代替先行词，在定语从句中充当主语、宾语或表语。
关系副词的作用有：代替先行词所表示的抽象内容，引导定语从句所缺少的成分。
3. 定语从句的位置和结构：定语从句通常位于先行词之后，与先行词之间有逗号隔开。
定语从句的结构与简单句相似，包括主语、谓语和其他修饰成分，只是其主语通常由关系代词或关系副词引导。
4. 定语从句的特点：定语从句既起着修饰作用，又起着句子成分的作用。
它插入到主句中，可以使句子更加丰富和准确。
以下是几个例子来说明定语从句的应用：- The book that you borrowed from the library is very interesting.（你从图书馆借的那本书很有趣。
）- The student who won the competition received a scholarship.（赢得比赛的那位学生获得了奖学金。
）- This is the place where we met last summer.（这是我们去年夏天见面的地方。
）- Do you know the reason why he resigned from his job （你知道他为什么辞去工作吗？）通过使用定语从句，我们可以给予更多关于名词或代词的描述和信息，帮助读者更好地理解句子含义。
定语从句(教学案)-2020年高考英语二轮复习精品资料Word版含解析
定语从句的用法较为复杂，高考除了单独考查定语从句知识外，还常常结合句式结构、时态等来综合考查。
纵观近几年各地高考试题，不难发现其考点主要包括：1．考查关系代词和关系副词的区分。
如：that，which和where，when的区分； that，which和why的区分等。
2．考查whose的使用。
whose可以指代人或物，在定语从句中作定语，后跟名词。
指物时，whose＋名词＝名词＋ of which ＝ of which＋名词。
如：The classroom whose door/the door of which/of which the door is broken is on the second floor.3．考查as/which引导的非限制性定语从句。
尤其要重视which，as引导的非限制性定语从句和it，what引导的主语从句的区分。
4．考查定语从句中的主谓一致现象。
如：I, who am your close friend, will try my best to help you whenever you are in trouble.5．考查“介词＋关系代词”引导的定语从句。
“介词＋关系代词”引导的定语从句，关系代词指人时用whom，指物时用which，不能用that。
关系代词作定语时也可用whose。
如：The teacher in front of whose house stands a tall tree is very patient with his students.同时还要重视“复杂介词或代词”出现时与并列句的区别。
如：He loved his parents deeply, both of whom are very kind to him.(定语从句) He loved his parents deeply and both of them are very kind to him.(并列句) 此外，“介词＋which ＋名词”结构，也是一个较为特殊的结构。

高中英语语法专项复习 八、英语语法 定语从句二 实用学案 新人教版
八、英语语法定语从句（二）2）定语从句的种类在英文中，有两种定语从句：限定性定语从句与非限定性定语从句。
这两种定语从句在其功能和形式方面都有明显的区别：限定性定语从句限定性定语从句与主句的关系很紧奏，对其先行词起限定、修饰的作用。
如果将其去掉，会影响句子意思的完整性；有时甚至于引起费解、误解。
例如：Rainforests are being cleared for valuable timber and other resources to speed up the economic growth of the nationsin which they are locate d .为了加速他们各自所在国家的经济发展，热带雨林作为有价值的原木和其他资源正为人们所砍伐。
Ocean currents affect the climates of the lands near which they flow.洋流影响其流经的附近地区的气候。
They explained the reason to us why they had hated us before.他们向我们解释为什么他们不喜欢我们的原因。
非限定性定语从句非限定性定语从句在形式上就与主句很松散，它与主句之间有一个逗点"，"隔开；它对其先行词没有限定、修饰的作用，只起补充、说明的作用。
有时也用它来对全句进行补充、说明。
即使将其去掉，也不会影响句子意思。
由于上述原因，非限定性定语从句在表达意思方面也有别于限定性定语从句。
另外，非限定性定语从句在中文译文里，我们往往将其作为一个分句处理，而不把它作定语翻译。
例如：Earlier , the Babylonians had attempted to map the world , but they presented it in the form of a flattened disc rather than a sphere , which was the form adopted by Ptolemy .（此句中，非限定性定语从句是对先行词a sphere进行补充、说明。

2020届新高考英语二轮教师用书：第八讲 定语从句和名词性从句
第八讲定语从句和名词性从句语法项目(一) 定语从句定语从句是高考考查的重点，也是必考点之一，语法填空主要考查关系代词、关系副词的选用，故分清句子结构，搞清定语从句部分缺少何种成分至关重要。
语法填空考查形式均为无提示词型填空。
定语从句的重要性还体现在书面表达上，它属于高级句式，对提升文章的档次起着举足轻重的作用。
如何确定填关系代词或关系副词[思考趋向]1．依据句子成分，先确定是定语从句还是名词性从句，然后判定先行词，再判定关系词在从句中所作成分，最后确定填关系代词或关系副词。
2．知晓并列句与定语从句的主要区别在于：并列句是由and，but等并列连词连接，这时就不能再用引导定语从句的关系词了。
[典例感悟][典例1](2018·浙江卷6月)Many westerners ________ come to China cook much less than in their own countries once they realize how cheap it can be to eat out.解析：who/that[此处缺少引导定语从句并在定语从句中作主语的关系代词，故用who 或that。
][典例2](2018·江苏卷)Self-driving is an area________China and the rest of the world are on the same starting line.解析：where[句意：无人驾驶是一个中国和世界上其他国家处于同一条起跑线上的领域。
考查定语从句。
设空处引导的是定语从句，修饰先行词an area。
将先行词代入定语从句后为China and the rest of the world are on the same starting line in_the_area.由此可知先行词与表地点的介词in一起在定语从句中作地点状语，所以要用关系副词where。

高考英语二轮语法复习学案
高考英语二轮语法复习学案（定语从句）（一）定语从句一般由关系代词和关系副词引导1、关系代词：who, whom, whose, which, that, as2、关系副词：when, where, why关系代词和关系副词必须位于从句之首，主句先行词之后，起着连接先行词和从句的作用，同时在从句中又充当句子成分。
e.g. She is the girl who sings best of all.（关系代词who在从句中作主语）The comrade with whom I came knows French.（whom在从句中作介词with的宾语）3、关系代词和关系副词的用法：1）当先行词为人时用who 作主语，whom作宾语；2）当先行词为物或整个句子时用which ，可作主语或宾语；3）先行词为人、物时用that ，可作主语或宾语；4）whose用作定语，可指人或物；5）关系副词when（指时间，在定语从句中作时间状语，where（指地点，在定语从句中作地点状语），why（指原因，在定语从句中作原因状语）。
（二）限制性定语从句与非限制性定语从句1、限制性定语从句：从句与主句关系密切，去掉从句，主句意义不完整，甚至不合逻辑。
e.g. I was the only person in our office who was invited.（去掉定语从句，意思就不完整）2、非限制性定语从句：从句对先行词关系不密切，去掉定从句，意思仍然完整。
形式上用逗号隔开，不能that用引导。
e.g. Tom’s father, who is over sixty, still works hard day and night.（who引导非限制性定语从句，整个句子可分成两句来翻译）（三）使用定语从句时特别注意的几个问题1、that与which的区别。
1）用that而不用which的情况：①先行词为不定代词all, anything, nothing, …；②先行词有最高级修饰，有序数词修饰；③先行词有only, very, any等词修饰；④先行词既有人又有物时。

读句子，猜猜他是谁？He is a player who is very famous in the world.Heplaysfootballwhichispopularallovertheworld.Heisamanwhosewifeisaworld-famoussinger.He lives in the country where the 2012 Olympic was held.Hewastheleaderoftheteamintheyearwhenthe18thWorld Cup washeld.Do you know the reason why he is so famous and successful?定语从句2 / 9定语从句的概念一、定语的概念句子中修饰名词或代词的成分叫做定语。
定语可以由形容词，名词，不定式， 分词，动名词或从句来充当，且定语往往翻译为“…的”。
指出下列句子中的定语由何种词句充当：① I have a pretty dog. 答案：pretty 形容词② He is in the reading room. 答案：reading 现在分词二、定语从句的概念在复合句中修饰名词或代词的从句叫定语从句。
被定语从句修饰的词叫先行词（跑在前面的词），定语从句一般紧跟在它所修饰的先行词之后。
在先行词和定语从句之间起连接作用的词叫关系词。
1) 定语从句的结构：圈出每句中被修饰的名词。
He is a player who is very famous in the world.即学即练Heplaysfootball which ispopularallovertheworld. Heisamanwhosewifeisaworld-famoussinger.He lives in the country where the 2012 Olympic was held.

Do you know the reason why he is so famous and successful?指出如下句子的先行词、关系词和定语从句：The boy who broke the window is Tom’s brother.He was the leader of the team in the year when the 18th World Cup was held.先行词：the boy、the year关系词：who、when定语从句：who broke the window is Tom’s brother.when the 18th World Cup was held.2)为什么有不同的关系词？He is a player who is very famous in the world.拆分：He is a player. The player is very famous in the world.（主语）拆分句子，并观察先行词在从句中充当什么成分。
I have never seen the girl who you mentioned yesterday.She is the teacher who we want to visit.关系词常有三个作用：即学即练1.引导定语从句2.代替先行词3.在定语从句中担当一个成分结论：在定语从句中，关系词如何选择，关键要看先行词在定语从句中作什么样的成分。
但先行词可以是人、物、地点、时间、原因等，所以要区分开讲。
关系代词常见的关系代词关系代词先行词句中成分例句who 人主语，宾语(可省略)A teacher is a person who/that passes knowledge tostudents.He is the man( who/ whom/ that) I sawyesterday.whom 人宾语(可省略) The woman (whom) you met in the street isKate. whose 人或物定语Please pass me the book whose cover is green.

➢H ere is a hotel that you’ve been looking for.②不不定代词后，如something，anything，everything，much, few, none, all 等。

➢Let me show you the novel that I borrowed from the library which was newly ope.做题两步走：1.找到从句划括号：连接词起，第二个动词前止。
2.根据成分选连词一看指人还是物，二看介词在何处；三看充当啥成分，四看是否属特殊。
4.先行词是句子（非限制性定语从句）常见的固定表达有:as we all know正如大家所知as is well-know众所周知as often happens这经常发生as is often the case情况总是如此as(is) mentioned above如上所述as has been said before如前所述as I can remember正如我所记得的as has been pointed out正如已经指出的as may be imagined正如可以想象出来的那样as we expect/ as is expected正如我们预料的那样拓展：(1)as用作关系代词，既可指人，也可指物。

➢This is the same bike as I lost two months ago.这辆自行车像我两个月前丢的那辆。
