高中英语定语从句总结？(1) “介词＋关系代词“可以引导限制性定语从句，也可以引导非限制性定语从句。“介词＋关系代词“结构中的介词可以是 in, on, about, from, for, with,to at, of, without 等，关系代词只可用whom或 which,不可用 that 。(2) from where为“介词＋关系副词“结构，但也可以引导定语从句。那么，高中英语定语从句总结？一起来了解一下吧。
whose引导的定语从句，总体特征，就是whose 与先行词的关系，是从属关系，只要明白了这一点，以下就好办了！就来看两个例子吧：this is our classroom whose windows are broken.there are many trees whoes leaves are red. 第一个句子：这是我们的教室，它的窗户坏了。第二个句子：那里有很多树， 它的叶子是红色的。注意我两个句子中我用的“它的”，就很好的说明了，先行词和whose的从属关系。 多说无益，相信你能体会出其本质。

高中英语语法定语从句
定义：用来说明主句中某一名词或代词（有时也可说明整个主句或主句中一部分）而起定语作用的句子叫作定语从句。
一、关系带词引导的定语从句
1.关系代词用来指代先行词是人或物的名词或代词
例1：ThisisthedetectivewhocamefromLondon.
例2：ThebookwhichIamreadingiswrittenbyTomasHardy.
2．关系代词的用法
(1)如果先行词是all,much,anything,something,nothing,everything,little,none等不定代词，关系代词一般只用that，不用which。例如：Allthepeoplethatareburstintotears.（所有人都迸出眼泪。）
(2)如果先行词被形容词最高级以及first,last,any,only,few,most,no,some,very等词修饰，关系代词常用that,不用which,who，或whom。
(3)非限制性定语从句中，不能用关系代词that,作宾语用的关系代词也不能省略。
一、定语从句 引导定语从句的关系代词有that, which, who（宾格whom），所有格whose）和关系副词 where when why 等，关系代词或关系副词在定语从句中充当一个成分，关系代词that，which, who, whom等在从句中分别作主语或宾语，whose在从句中作定语，而关系副词when, where, why等在从句中作状语。如：①I will never forget the days when/in which we worked together.②I will never forget the days which/that we spent together.解析：在句①中，表示时间的名词the days在从句中充当的是状语，所以用关系副词when来代指，引导定语从句修饰先行词the days；而在句②中，表示时间的名词the days在从句中充当的是动词spent的宾语，所以用关系代词that或which来代指。同样，表示地点或原因的名词如果在从句中作状语，则用关系副词where 或why来代指；如果在从句中作动词的宾语，则用which或that来代替。
定语从句解析
1.定义：定语从句在句中作定语，修饰名词或代词，被修饰的名词或代词称作先行词。
2.分类：限制性定语从句————主从句间无逗号
非限制性定语从句————主从句间有逗号，补充说明
3.十大连词：
关系代词：which、that、whom、who、as、but、whose
关系副词：where、when、why
4.关系副词PK关系代词
a).She has never forgot those days when/during which she has stayed in the boy's school.
b).She will never forgot those daysthat/which she has spent in the boy's school.
这两句中，a)的从句完整，并不缺成分，只看从句，也是一句完整的句子。用关系副词(或介词+关系代词）
b)的从句不完整，spent 后应加时间，而从句中没有表时间的词。用关系代词
c)This is the hospital where/in which/for which she works for 40 years.（从句完整）
d) this is the hospital that /which she has worked for for 40 years.（从句不完整）
这两句同上。
1. The factory was built in a secret place, around _________ high mountains.
A. which was B. it was C. which were D. them were
【陷阱】容易误选A或B，将A、B中的 which 和 it 误认为是其后句子的主语。
【分析】最佳答案是C，around which were high mountains 是一个由“介词+which”引出的非限制性定语从句，而在该从句中，主语是 high mountains，around which 是表语，所以句子谓语应用复数were，而不是用单数 was。请做以下类例题目（答案均为C）：
(1) Yesterday we visited a modern hospital, around _________ some fruit shops.
A. which is B. it is C. which are D. them are
(2) The murder happened in an old building, beside _________ the city police station.
A. which are B. it is C. which is D. them are
(3) Next month we’ll move to a new building, next to _________ a nice restaurants where we can have Chinese food.
A. which are B. it is C. which is D. them are
2. A man with a bleeding hand hurried in and asked, “Is there a hospital around _________ I can get some medicine for my wounded hand”
A. that B. which C. where D. what
【陷阱】容易误选 B，认为 around 是介词，选 which 用以代替前面的名词 hospital，在此用作介词 around 的宾语。
以上就是高中英语定语从句总结的全部内容，1. 当定语从句中含有介词,介词放在句末时,who,whom, that,which可省略,但介词在关系代词前时,只能用“介词+which/whom”结构。例如: This is the house in which we lived last year. 这是我们去年居住的房子。
