专题八定语从句基础知识过关一、定义在复合句中, 修饰名词或代词的从句称为定语从句。
被定语从句修饰的词叫先行词, 定语从句必须放在先行词的后面, 由关系代词或关系副词引导, 关系词充当从句的成分。
The student that won the first prize is our monitor. (that代替the student在从句中作主语)I saw some trees whose leaves were yellow. (whose在从句中作定语)The watch which I found in the library is his. (which代替watch, 在从句中作宾语)This is the place where he works. (where相当于in the place, 在从句中作地点状语)二、限制性定语从句与非限制性定语从句三、使用定语从句时特别注意的几个问题1. that与which的区别。
(1)用that而不用which的情况:①先行词为不定代词all, anything, nothing等②先行词被little, few, no等词修饰时③先行词被形容词最高级或序数词修饰时④先行词被the only, the very, the last等修饰时⑤先行词既有人又有物时She told me everything that she knew.This is the best novel that I have ever read.We know nothing about the doctors and the hospitals that you are talking about.(2)用which而不用that的情况:①引导非限制性定语从句②代表整个主句的意思③介词+关系代词This is the factory in which we once worked.The baby was ill, which made the mother very worried.2. 关系代词在从句中作主语时, 从句谓语动词的单复数形式应由先行词决定。
