定语从句中的介词有时可置于关系代 词之前，形成“介词+关系代词”结构。 关系代词通常是which和whom； which指物，whom指人。
1. 介词+which在所引导的定语从句中作时间状语、 地点状语、原因状语等。 关系副词 when (=at/in/on /during/ …which) where (=in/at/… which) why (=for which) 在从句中的作用 时间状语 地点状语 原因状语

完整版)高中英语定语从句讲解及练习
完整版)高中英语定语从句讲解及练习定语从句是高中英语的重点知识，也是高考常考点。
本文将主要讲解关系代词引导的定语从句，并解释关系副词引导的定语从句，包括判断关系代词与关系副词限制性和非限制性定语从句等内容，并提供例题讲解。
定语从句在句中作定语，修饰一个名词或代词，被修饰的名词词组或代词即先行词。
通常出现在先行词之后，由关系词（关系代词或关系副词）引出。
关系代词有：who。
whom。
whose。
that。
which等。
它们代替的先行词是人或物的名词或代词，并在句中充当主语、宾语、定语等成分。
当关系代词在定语从句中作主语时，从句谓语动词的人称和数要和先行词保持一致。
例如，当先行词是人时，可以使用who或whom作为关系代词。
如：Is he the man who/that wants to see you?（他就是你想见的人吗？）关系代词在从句中作主语。
而当先行词是物时，可以使用which或that作为关系代词。
如：The package（which / that）you are carrying is about to come unwrapped.（你拿的包快散了。
）关系代词在从句中作宾语。
除了who。
whom。
whose。
that。
which，还有关系副词when。
where。
why等。
关系副词引导的定语从句也可以修饰一个名词或代词。
例如：I still remember the day when we met.（我仍然记得我们相遇的那一天。
）关系副词when在从句中作时间状语，修饰先行词day。
总之，掌握定语从句的用法和关系词的选择是英语研究的重要内容。
通过不断的练和实践，相信大家可以掌握这一技能。
关系副词可以代替时间、地点或理由的名词，在从句中作状语。
例如，关系副词when。
where。
why的含义相当于“介词+ which”结构，因此常常和“介词+ which”结构交替使用。
比如，有时候我们必须屈服，这是任何人都会遇到的情况（There are ns when [on which] one must yield）。

高中英语定语从句语法精讲练习(带答案)
高中英语语法讲解——定语从句(名师精讲必考语法知识点+实战训练，建议下载练习)一、先行词、关系代词和关系副词1．先行词(antecedent)就是被定语从句所修饰的名词。
在英语中，定语从句跟在被修饰词之后，所以被修饰词就是“先行”的词。
eg. The lovely girl often helps the old lady.She lives next door to our school.→The lovely girl who lives next door to our school often helps the old lady.→The lovely girl often helps the old lady who lives next door to our school.The lovely girl often helps the old lady.You met her at school yesterday.→The lovely girl (whom)you met at school yesterday often helps the old lady.→The lovely girl often helps the old lady (whom) you met at school yesterday.2．连接定语从句，要用关系代词(relative pronoun)和关系副词(relative adverb)。
关系代词和关系副词与连接词不完全相同，因为它们除了连接主句和定语从句，还在定语从句中代替一定的成分。
eg. The book which I bought yesterday is very interesting.← The book is very interesting. I bought the book yesterday.I have visited the house where Andersen wrote The Emperor’s New Clothes.←I have visited the house. Andersen wrote The Emperor’s New C lothes in the house.二、关系代词1．who的先行词是“人”，在从句中代替主语。
