初中英语语法梳理和提高：定语从句讲解及试题
　　在复合句中，修饰某一名词或代词的从句叫做定语从句。
　　知识梳理：提纲挈领，抓住重点和难点！
　　定语从句所修饰的词 叫先行词。 定语从句放在先行词后面。定语从句分为限定性定语从句和非限定性定语从句。本章只介绍限定性定语从句。引导定语从句的词有关系代词that、which、who、 which、 whose和关系副词where 、when，关系代词和关系副词是引导词， 在定语从句中担当某一成份。
　　关系代词和关系副词的作用：
　　先行词指物时， 关系代词用that 或which（在句中作主语或宾语）。
　　如：China is a country which / that has a large population.
　　The computer game which/ that he is playing is his favorite.
　　先行词指人时， 关系代词用（who）作主语或宾语，whom (作宾语)，whose (作定语)，that (作主语或宾语)。 如：
　　The man who is mending the machine has been retired.
　　This is the policeman who/ whom they were talking about yesterday.
　　I like the girl whose mother is an actor.
　　注意：下列情况下关系代词只用that 而不用which 或 who。
　　先行词是指物的不代词，如：all, little, few, much, none, anything, nothing, everything等时。如：I didn't understand the words all that he said.
　　2．先行词由最高级、序数词以及any, very, only, all, no, just 等所修饰。如：This is the most beautiful place that I have been to .
　　行词既包括人，也包括物。如：They always like to talk about the man and the things that they see on the road.
