文档介绍：定语从句难点解析定语从句的引导词分为关系代词( who , whom , whose , which , that ) 和关系副词( where , when , why ) 两类, 这些引导词在引导定语从句的同时均在从句中充当成分。关系代词可作主语、宾语和定语, 作宾语时可省略; 关系副词可作状语, 一般不能省略。下面简单介绍一下定语从句的难点。一、介词(短语) + 关系代词/ 副词 1. 此处关系代词只能是 which / whom / whose / where / when ,而不能用 who / that. 如: They arrived at an old building , in front of which stood a tower. He climbed up to the top of the tree , from where he could see clearly what was happening in the woods. 2. 不定代词/ 数词+ of which / whom. 如: Mrs. Green has three sons , none of whom works in the city. The boys discovered many pictures on the walls of the cave , most of which dated back to 15, 000 years ago. 比较: The boys discovered many pictures on the walls of the cave , most of them dating back to 15, 000 years ago.

(此处为独立主格结构) 三、 which 和 as which 和 as 都可引导非限制性定语从句,用来指代整个主句的内容, which 引导的从句只能放在主句后, as 引导的从句放在主句前后均可; which 意为“这一点”, as 意为“正如”。 as 还可用于 the same …… as, such …… as 等结构中, 引导限制性定语从句。如: He turned out to bea great ess asa dancer , which was more than we could expect. As is known to all , Madame Curie is the first woman scientist in the
