1、高考英语语法核心考点专项复习10：定语从句 什么是定语？ 定语是用来修饰、限定、说明名词或代词的品质与特征的。 主要有形容词，此外还有名词、代词、数词、介词短语、动词不定式(短语)、分词、定语从句或相当于形容词的词、短语或句子都可以作定语。 汉语中常用 的 表示。例 a beautiful girl the noisy music什么是定语从句？一、定义：在复合句中，修饰名词或代词的句子叫作定语从句。例 I like the book which is about tale story. Please tell me the reason why you missed the plane. 二
2、、先行词：定语从句在句中作定语, 用来修饰某个名词或代词, 这个名词或代词叫先行词, 而定语从句位于先行词的后面。三、关系词：用来引导定语从句的词叫做关系词。关系词分关系代词(that, which, who, whom, whose)和关系副词(when, where, why)。关系词常有3个作用：1.连接作用。连接主句和从句。 2.指代作用。指代先行词 3.在从句中充当一定成分。指人指物所作成分关系代词that主语、宾语、表语which主语、宾语、表语who主语、宾语、表语whom宾语whose定语as主语、宾语、表语关系副词when时间状语why原因状语where地点状语注意：that
3、和which的用法区别1只用which不用that的情况(1)在非限制性定语从句中，which既可代表先行词又可代表前面的一整句话，译成“这一点，这一件事”。(2)在介词后面。(3)先行词是代词that或those时。2只用that不用which的情况(1)当先行词是all, everything, anything, nothing, much, none等不定代词时，只用that。(2)先行词被序数词或形容词最高级修饰时，只用that。(3)如果出现两个或两个以上的先行词，并同时兼指人和物时，关系代词用that。(4)先行词被the only, the last, the way等修饰时用
4、that。(5)在疑问词who, which, what开头的特殊疑问句中，为了避免重复只用that。四、“介词 关系代词” 引导的定语从句作介词宾语的关系代词一般是which和whom，“介词which/whom”既可以引导限制性定语从句，又可以引导非限制性定语从句。常见的有以下几种结构：1介词 关系代词Mandela was the black lawyer to whom I went for advice. Mandela was the black lawyer whom I went to for advice. 曼德拉是我寻求建议的一位黑人律师。2名词/代词/数词介词关系代词La
5、st Sunday I bought some books from the bookstore, three of which were English novels. Last Sunday I bought some books from the bookstore, of which three were English novels. 上个星期天，我从书店买回几本书，其中三本是英文小说。3形容词最高级 介词 关系代词China has thousands of islands, the largest of which is Taiwan. 中国有成千上万的岛屿，其中最大的是台湾。四
6、、限制性定语从句和非限制性定语从句定语从句有限制性和非限制性两种。限制性定语从句与其先行词之间不用逗号隔开，非限制性定语从句与其先行词之间一般用逗号隔开。限制性定语从句是主句不可缺少的部分，去掉它主句意思往往不明确；非限制性定语从句起补充说明作用，去掉了不会影响主句的意思，它与主句之间通常用逗号分开。如：People who take physical exercise live longer.进行体育锻炼的人活得更长些。(限制性定语从句，若把从句去掉句子的意思就不完整。)His daughter, who is in Boston now, is coming home next week.
7、他女儿现在在波士顿，(她)下星期回来。(非限制性定语从句，若把从句去掉句子意义仍然完整。)五、必须注意的几个问题1定语从句与状语从句、同位语从句及强调句的辨析比较例句区别与where引导的地点状语从句的区别Years later, he went to New York, where/in which he made great success.The tree should be planted where there is plenty of rain.where引导的是定语从句，修饰先行词，在从句中作状语，where可以转化为“介词 which”。 句中where引导的从句前无先行词，因
8、此引导的是地点状语从句，where本身在从句中作状语，不能转化为“介词关系代词”。 比较例句区别与同位语从句的区别This is the suggestion(that) he put forward. He gave me a suggestion that we should start at 5 oclock. that引导的是定语从句，that代替先行词在从句中充当宾语。同位语从句中连接词that 在从句中无意义，不作成分但不可省略。与强调句的区别It was last night that I saw the accident.It was a time when there wer
9、e still slaves.判断强调句的方法是把it is/ was和 that (who) 去掉，如果句子仍然完整，则是强调句。(句去掉it wasthat 成为I saw the accident last night.) 2.“使用where而非真实地点”型定语从句定语从句的先行词是situation, case, point, scene等名词而且从句缺少状语时，要使用where表示“一种特定的情况”或“一个特定的场合”。如：I have come to the point where I cant stand him. 我已经到了无法容忍他的程度。Hes got himself i
