由关系副词when, where, why引导的定语从句
由关系副词when, where, why引导的定语从句 1. 基本用法定语从句除可用关系代词引导外,还可用关系副词when, where与why来引导,它们的区别是:when用于指时间,where用于指地点,why用于指原因。when, where, why 在定语从句中均用作状语。如:1980 was the year when he was born. 1980是他的出生年。This is the town where I was born. 这就是我出生的城市。This is the town where I was /SPAN>
These are the reasons why we do it. 这些就是我们这样做的理由。
2. 先行词问题关系副词when和where的先行词是表示时间(如the day, the days, the time, the year等)和地点(如the place, the house, the factory, the station等)的一类词,而关系副词why的先行词通常只是whythe reason(s)。另外,when和where可引导限制性和非限制性定语从句,而why则只用于引导限制性定语从句,不用于引导非限制性定语从句。
3. 一点注意注意不要以为在时间名词后就一定用关系副词when,在地点名词后就一定用关系副词 where,在表示原因的the reason后就一定用关系副词why。到底选用关系副词还是关系代词,关键是看它们在定语是用作状语(用关系副词)还是用作主语或宾语(用关系代词)。如:Don’t forget the time (that) I’ve told you. 不要忘记我告诉你的时间。(that用作told的宾语)I’ll never forget the days when I worked with you. 我永远不会忘记我与你共事的日子。(when用作状语)He works in a factory that [which] makes radio parts. 他在一家制造无线电零件的工厂工作。(that, which 在从句中用作主语,且不能省略)He works in the factory where his father worked. 他在他父亲工作过的那家工厂工作。(where作状语)That’s the reason that [which] he explained to us. 那就是他向我们解释的理由。(that或which在从句中用作explained的宾语)
That’s the reason why she left home. 那就是她离家出走的原因。(where在从句中作状语)
4. 一个错点英语中的关系副词主要是 when, where, why三个。不要想当然地将how用作关系副词修饰the way。可使用如下表达方式: This is how he spoke(how引导的是表语从句),或This is the way (that, in which) he spoke.(其中的that, in which可省略)
