初中英语从句语法总结

初中英语从句汇总在英语中,主要有三大从句,即名词性从句(包括主语从句,宾副词性从句(即状语从句,包括时间、条件、结果、目的、原因、让步、地点、方式等)。
以下是一些基本的从句的语法知识点定语从句:一、定语从句概念定语从句(attributive clause),顾名思义,就是一个句子作定语从属于主句。
定语一般是由形容词充当,所以定语从句又称作形容词从句。
另外,定语从句是由关系代词或关系副词引导的,故又称作关系从句。
定语从句一般放在它所修饰的名词或代词之后,这种名词或代词被称作先行词。
请看示例:The woman who lives next door is a teacher.1.先行词与关系词先行词就是被定语从句修饰的名词、代词等,它总是出现在定语从句的前面。
关系词指用来引导定语从句的词,分为关系代词和关系副词,关系代词在定语从句中作主语、宾语、表语、定语等,关系副词在定语从句中作状语。
1)关系代词2)关系副词1)判断哪一部分是先行词,先行词指人、物、时间还是原因The book which/that I left here just now is gone. 我刚才放在这里的书不见了。
(the book 是先行词,指物)I'll forever treasure the days which/that we spent on the seashore. 我将永远珍惜咱们在海滨一起度过的那些日子。
(the days, 指时间)2)确定关系词。
既要考虑先行词,又要考虑关系词在从句中充当的成分。
比较: I'll forever treasure the days which/that we spent on the seashore.我将永远珍惜咱们在海滨度过的那些日子。
(先行词是the days,指时间,在定语从句中作spent的宾语,因此选择关系代词which或that)I'll forever treasure the days when we played on the seashore.我将永远珍惜我们在海滨玩耍的那些日子。
