定语从句用法总结一. 定义：定语由一个句子来充当，那么这个句子就叫做定语从句.eg：The old town has narrow streets and small houses that are built close to each other 。其中划线部分为定语从句。二. 分类:分为限制性定语从句和非限制性定语从句,还有间隔性定语从句。eg： 1。This is the school （that/which）we visited last year。 (限制性定语从句） 2。The weather turned out to be very good，which was more than we could expect. (非限制性定语从句) 3。The days are gonewhenphysical strength was all you needed to make a living。（ 间隔性定语从句）注：定语从句和非限制性定语从句的区别限制性定语从句无逗号隔开、不可缺少、起修饰限制作用；而非限制性定语从句有逗号隔开、可有可无、起补充说明作用。三. 构成:定语从句有先行词、引导词和从句构成.先行词是定语从句所修饰限制的名词或代词.引导词是用来引导定语从句的关系代词或关系副词.eg： The old town has narrow streets and small houses that are built close to each other.此句中先行词为：narrow streets and small houses，引导词为:that, 定语从句为：that are built close to each other四．基本原则定语从句中不能出现与先行词在意义上相一致的词Eg。This is the book that I like it best .（it 与 book 指同一物，所以要去掉。)五．定语从句中常见考点:考点一.关系代词和关系副词的辨别1。 关系代词 that（人、物），which（物）、who(m)(人）、whose(某人的，某物的)、as2。 关系副词 when(表时间）、where（表地点)、why(表原因）注:关系副词可变为“介词+关系代词"结构（即:关系副词=介词+关系代词）。eg：This is the mountain village where（=in which）I stayed last month。3。 怎样选择正确的关系代词或关系副词方法一：找出先行词和定语从句中动词，看定从中动词与先行词能否构成习惯搭配。能，用关系代词;不能，用关系副词.Eg。I will never forget the day that I spent with my parents。（定从中动词 spent 与先行词 the day 构成 spent the day ，所以用关系代词 that 或 which 或省略)方法二：找出先行词和定语从句，看定语从句是否缺少主语、宾语或表语，如缺少,用关系代词。如不缺少，定...
