Unit 4 Grammar and usage 如何区分关系代词和关系副词讲义-2023-2024学年高中英语牛津译林版（2020）必修第一册

定语从句中如何区分关系代词和关系副词 一. 区分 I. 关系代词是代词，在从句中充当成分（主语，宾语，表语，这类为必要成分，不可缺少）。 例句1: · 先看整句： Take care of the girl and her dog that are crossing the street. 主句 从句 · 再看从句： that are crossing the street. 主语 谓语动词 宾语 · 故thay在从句中作主语 例句2： · 先看着整句： The Science Museum, which we visited during a recent trip to Britain, is one of London’s tourist attractions. 划线部分为主句，非划线部分为从句 · 再看从句： which we visited during a recent trip to Britain 宾语 主语 谓语 状语 · 故which在句中作宾语 II. 而关系副词是副词，在从句中作状语（状语是修饰成分）。 例句1: · 先看整句 Occasions are quite rare when I have the time to spend a day with my kids. 主句 从句 · 再看从句 when I have the time to spend a day with my kids. 时间状语 主语 谓语 目的状语 When = on the occasion, 即介词+名词。 · 故when在从句中作时间状语，是副词。 例句2： · 先看整句： Tom took me to see the house where I would be staying. 主句 从句 · 再看从句 where I would be staying 地点状语 主语 谓语动词 where= in the house 即介词+名词。 · 故where在从句中作时间状语。 二. 实战练习 第一组： 1.

However, there are a number of other reasons ____ might explain why you want to garden. 先分析第一个句子： · 先看整句 There are several reasons ________ school uniforms are a good idea. 主句 从句 · 再看从句 ________ school uniforms are a good idea. 主语 谓语 表语 从句部分主系表的结构已经完整，故空格部分应填关系副词Why（副词不是必要成分，是修饰成分） 第二个句子： · 先看整句 However, there are a number of other reasons ____ might explain why you want to garden. 主句 从句 · 再看从句 _________ might explain why you want to garden. 主语 谓语动词 原因状语 句子必要成分缺主语，空格处填关系代词which。 第二组 1.
