2023年高考英语语法精讲:定语从句考点分析
一、定语从句中关系副词的用法
1、关系副词when的用法
when 既可引导限制性定语从句,又可引导非限制性定语从句。先行词是时间名词,在从句中充当时间状语,相当于“介词+which”。如:
Can you tell me the time when the film will start?—Can you tell me the time at which the film will start? 请告诉我电影什么时候开始好吗?(限制性定语从句)
I will never forget the day, when I joined the Party. —I will never forget the day, on which I joined the Party. 我入党的那一天,我永远不会忘记。(非限制性定语从句)
2、关系副词where的用法
where既可引导限制性定语从句,又可引导非限制性定语从句。先行词是地点名词,在从句中充当地点状语,相当于:“介词+which”。如:
This is the school where I studied a few years ago. —This is the school in which I studied a few years ago. 这就是我几年前所在读书的学校。
Lets go to the concert, where you will find much fun. —Lets go to the concert, in which you will find much fun. 我们去音乐演唱会吧,在那里你会找到很大的乐趣。
3、关系副词why的用法
why只能引导限制性定语从句,先行词只有reason一词,在从句中充当原因状语,相当于:“for + which”。如:
Do you know the reason why he is not here now?—Do you know the reason for which he is not here now? 你知道他还没有来这儿的原因吗?
4、关系副词that的用法
that只能引导限制性定语从句,充当关系副词时,其作用相当于:“介词+关系代词”,在从句中充当时间、地点、方式、原因状语等。如:
1. 在定语从句中作时间状语。现行词有:each time, every time, anytime, the first time, the moment, the minute, the hour, etc. 但现代英语中,that往往省略。如:
Each time (that) I meet him, he will smile and say "hello". 每次我会见他时,他都会笑着说“喂,你好!”
2. 在定语从句中作方式状语, 现行词是way, 如:
Can you show me the way (that) you solve the problem like this? 请告诉我你解决这类问题的方法好吗?
3. 在定语从句中作原因状语,现行词只有reason一词,如:
I don’t know the reason (that) he has left school now. 我不知道他辍学的原因。
4. 在定语从句中做其他状语,现行词如price, speed等,如:
I think the price (that) she sells her apple is too high. (that = at which) 我认为她卖苹果的价格太高。
二、两组关系代词的用法辨析
1、that 与 which:两者都可指物,常可互换,其区别是:
(1) 引导非限制性定语从句或直接放在介词后作宾语时,要用which。如:
Peter drove too fast, which was dangerous. 彼得开车很快,这是很危险的。
This is a subject about which we might argue for a long while. 这是一个我们可能长时间争论的问题。
(2) 当先行词为不定代词或被其修饰、受the very, the only, the same 等修饰、受形容词最高级或序数词(包括last, next)等修饰、关系代词在定语从句中用作表语或先行词是一个既指人又指物的并列词组时,通常用that。如:
All that can be done must be done. 凡能做的事都必须做。
This is the only book (that) I find useful. 这是我发现的唯
