雅思阅读中定语从句的语法知识先是给大家分享了定语从句的相关概念，然后具体分析了一些阅读真题的例子，希望可以提高大家分析长难句结构的能力。
一、定语从句的定义如果一个简单句放在一个名词或者代词之后，起修饰限定的作用，那么这个句子就叫做定语从句。
所修饰的名词或者代词叫做先行词，连接定语从句和先行词的词汇叫做关系词，可以分为关系代词和关系副词。
常见的关系代词有that/who/whom/whose/which，经常在从句中充当主语、宾语、定语等成分。
常见的关系副词有when/where/why/介词+in which/that，经常在从句中充当状语成分。
定语从句可以分为两大类：限制性定语从句和非限制性定语从句。
限制性定语从句是先行词不可分割的一部分，不能去掉，并且不能用逗号分开。
非限制性定语从句不仅可以对先行词也可以对整个句子进行修饰，与主句之间通常用逗号隔开，去掉并不会影响主句的内容。
一般，我们见到的大部分的定语从句都是限制性定语从句。
二、定语从句的知识点1. 关系代词引导限制性定语从句：例 1. Then, in 1912, an Italian 2-hour film was hugely successful, and Hollywood settled upon the novel-length narrative that remains the dominant cinematic convention of today. (剑6 Test 3 Passage 1)句子结构分析：这句话是由and连接的并列句。
第一句话是主系表结构：主语是an(Italian 2-hour)film，系动词是was，表语是successful，in 1912是插入语。
第二句话是主谓宾结构：主语是Hollywood，谓语是settled upon，宾语是the novel-length narrative，that引导限制性定语从句修饰先行词narrative，that是关系代词，在从句中做主语。

雅思阅读之定语从句分析在雅思阅读中，定语从句是一个重要的语法结构，通常用于修饰和限定名词，提供更多的信息。
以下是定语从句的几种类型以及它们的分析方法：1.限制性定语从句这种从句对被修饰的名词有严格的限制，不可省略，否则句子的意义会不完整。
例如：“The scientist who discovered the Higgs boson was awarded the Nobel Prize.”（发现希格斯玻色子的科学家被授予诺贝尔奖。
）2.非限制性定语从句这种从句对被修饰的名词没有严格的限制，可以省略而不影响句子的意义。
例如：“His father, who is a doctor, works in a hospital.”（他的父亲是一名医生，在医院工作。
）3.关系代词引导的定语从句关系代词如“that”、“which”、“who”等用于引导定语从句，指代被修饰的名词。
例如：“The1book that I borrowed from the library is very interesting.”（我从图书馆借来的书很有趣。
）4.关系副词引导的定语从句关系副词如“where”、“when”、“why”等也可以引导定语从句，用于修饰名词。
例如：“The reason why he was late for class was that he got up late this morning.”（他迟到的原因是他今天早上起床晚了。
）5.分隔式定语从句在这种结构中，定语从句与被修饰的名词被其他成分分隔开。
例如：“The company, which was founded in 1990, has grown rapidly in recent years.”（这家成立于1990年的公司近年来发展迅速。
）在分析定语从句时，首先要判断它是限制性还是非限制性的，然后确定关系代词或关系副词的意义和作用。
1.雅思口语的定语从句类型一、限定性定语从句1. that即可代表事物也可代表人，which代表事物;它们在从句中作主语或宾语，that在从句中作宾语时常可省略关系词，which在从句中作宾语则不能省略。
而且，如果which在从句中作“不及物动词+介词”的介词的宾语，注意介词不要丢掉，而且介词总是放在关系代词which的前边，但有的则放在它原来的位置。
2. which作宾语时，根据先行词与定语从句之间的语义关系，先行词与which 之间的介词不能丢。
3. 代表物时多用which，但在带有下列词的句子中用that而不用which，这些词包括all, anything, much等，这时的that常被省略。
4. who和whom引导的从句用来修饰人，分别作从句中的主语和宾语，whom 作宾语时，要注意它可以作动词的宾语也可以作介词的宾语。
5. where是关系副词，用来表示地点的定语从句。
二、非限定性定语从句非限定性定语从句起补充说明作用，缺少也不会影响全句的理解，它与主句往往用逗号隔开，如若定语从句有限制性和非限制性两种。
限制性定语从句是先行词不可缺少的部分，去掉它主句意思往往不明确;非限制性定语从句是先行词的附加说明，去掉了也不会影响主句的意思，它与主句之间通常用逗号分开，将非限定性定语从句放在句子中间，其前后都需要用逗号隔开。
2.雅思口语中的关系代词关系代词which在非限制性定语从句中所指代和修饰的可以是主句中的名词、形容词、短语、其他从句或整个主句，在从句中作主语、动词宾语、介词宾语或表语。
1. which指代主句中的名词，被指代的名词包括表示物、婴儿或动物的名词、表示单数意义的集体名词以及表示职业、品格等的名词。
如：These apple trees，which I planted three years ago，have not borne any fruit.这些苹果树是我三年前栽的，还没有结过果实。
