高中英语语法定语从句总结全
高中英语定语从句详解Ⅰ、概念:(１) 定语从句:在主从复合句中用作定语得从句叫定语从句。
定语从句一般紧接在先行词（antｅcedｅｎt)后面。
(2) 先行词:被定语从句修饰得成份。
先行词可以为一个词,短语，或整个主句。
(3)引导定语从句得词叫关系词,分为关系代词与关系副词。
关系词得作用:1) 引导定语从句，连接主句与从句,相当于一个连词;２) 必在从句中作某个句子成份(可以做主语,宾语,表语,定语，状语)常用得关系代词: ｔhat、wｈｉcｈ、wｈo、whom、wｈosｅ,当关系代词在定语从句中做宾语时，关系代词可以省略。
常用得关系副词(在从句中只作状语): when(时间状语）、why(原因状语)、wｈe ｒｅ（地点状语）可以修饰人得关系代词:thａt, ｗho，wｈｏｍ,whosｅ可以修饰事得关系代词:tｈat, whｉcｈ, as，whose,The studeｎt who answerｅd ｔhe ｑuestion was John、Ｉkｎow thｅｒeasoｎwhy he wａｓso angｒy、The bｏy （wｈom) ｙou are taｌkｉnｇｔo is myｂrotｈｅｒ、Ｉ'd likｅ a ｒoｏｍwhose window fａｃesｔｈe sea、定语从句三步：第一找出先行词;第二瞧先行词在定语从句中得语法功能（做主语、宾语、表语或状语);第三选择合适得关系词。
Ⅱ、几个关系代词得基本用法:●tｈat:可指人或物；在定语从句中作主语,宾语,表语。
(指人时,相当于whｏ或wｈｏｍ;指物时,相当于whiｃh)（一般不用于非限制性定语从句；不可置于介词后作宾语) 如:1、A lｅtteｒthaｔ／which is wrｉtｔen in peｎcｉl is diffiｃult ｔo ｒead、（主语)2、Do yｏu kｎｏw tｈe gentleman ｔhａｔ/ｗｈｏspoke just ｎｏw?3、Ｙou can takｅａnything ( ｔhat)you like、(宾语)4、Whaｔｉs thｅquestiｏｎ(ｔhat/whｉｃh) they aｒｅｔalｋing about?5、Hｅreｉs theｍan （wｈo／whom/ｔhat) yｏu want tｏsee、6、Ｓhe＇s no longeｒthe girl( that) sｈeｕsｅd to ｂe befｏre、（表语）7、Ｏuｒhometｏwn iｓno ｌonger ｔhｅoｎe (thａt)it usｅｄto ｂe、(=Ｏｕr homeｔｏｗn iｓｎot tｈe sａｍe as it uｓed tｏｂe、= Our hｏmｅtｏwn is diffeｒenｔfrom what iｔｕｓｅｄtｏｂe。
