英语主从复合句学习的四个关键
主从复合句是高中英语学习的一 个难点,也是一个重点。如何学习主从复合句,我认为应从以下四个关键着手:一 : 概念 主从复合句属于句子的种类,它包括简单句、并列句和复合句。简单句是由一套主语和谓语构成;并列句是由两个或两个以上的简单句并列构成,常用and ,but, so 等并列连词连接。复合句是由一 个主句和一个或一 个以上的从句构成。主句是全句的主体,往往可以独立存在;而从句仅是句子的`一 个成分,故不能独立存在,必须有一个关联词引导。引导从句的关联词共有七类:1) 从属连词 :有 whether ,when, although, because, if 等。I don’t know if he will come.2) 疑问代词 : who ,whom, whose, which ,what 等。I don’t know what you mean .3) 疑问副词 :when ,where ,how ,why等。I asked him where he was going to stay.4) 关系代词:who, whom , whose, which, that what 等,主要引导定语从句。The young man who is standing there is my English teacher.5) 关系副词:when, where, why.也可以引导定语从句。That was the time when we stayed together.6) 复合连接代词:what ,whatever, whoever, whichever 等。You can do whatever you like.7) 复合连接副词:wherever, whenever, however 等。You can come whenever it is possible.特别强调:主从复合句必须有连接词。英语是形和而汉语是意和。如汉语可以说“你来我走”,中间没有连接词。如翻译成英语必须根据意义加上连接词if ,否则句子就错误。If you come , I will go.再如“有饭同吃”,也要加连接词:If there is any food , let us share it.如果一 个句子前面用了一 个逗号,逗号前面决不能是个句子,但可以由以下几个成分:1: 不定式 To get there in time , He got up early.2:现在分词Hearing the good news, He jumped up and down.3:过去分词Beaten by his father , He run away from home.4):独立主格结构There being no bus , We had to walk home.5)分号:United , We stand; divided ,We fall.6)偶尔也有连接副词I had a drink ,then I went home.二:主从复合句的分类和比较名词从句(主语从句、宾语从句、表语从句、同位语从句)主从复合句 副词从句(状语从句) 形容词从句(定语从句)名词从句
