定语从句

关系副词的用法

关系副词指代的先行词

先行词 关系副词 在从句中的作用 介词 + 关系代词
表示时间的名词 time, day, year 等 when 作时间状语 = at/in/on/during which
表示场所的名词 park, place, country, house 等 where 作地点状语 = in/at/to/on which
表示理由的名词: reason why 做原因状语 = for which

when 的用法

when 指时间,在定语从句中作时间状语,先行词通常为 time, day, week, year, period, occasion(当 "机会、时机" 讲时), age等表示时间的名词。此时 when 可以用 on/in/at/during which 等代替。
-例句

因为金融危机,当地的五星级酒店一夜收取 6,000 元的日子一去不复返了。

We live in an age when more information is available with greater ease than ever before.
我们生活在一个比以往任何时候都更容易获取更多信息的时代。

where的用法

where 指地点,在定语从句中作地点状语,先行词通常为 place, town, country, room 等表示地点的名词。
-例句
The book has helped me greatly in my daily communication, especially at work where a good impression is a must.
这本书在日常交际方面帮了我很大的忙,尤其是在工作中,在工作中好的印象是必不可少的东西。
A bank is the place where they lend you an umbrella in fair weather and ask for it back when it begins to rain.
银行是在天晴之时借给你伞,到了下雨就让你还回去的地方。
Stephen Hawking believes that the earth is unlikely to be the only planet where life has developed gradually.
P.H.认为地球不可能是唯一有生命逐渐进化的行星。

关系副词 where 的先行词还可以是一些表示抽象意义的词,例如:case, situation, point, scene, stage, position, condition, occasion(当“场合”讲时)等。
-例句
Today, we'll dicuss a number of cases where beginners of English fail to use the language properly.
今天我们将讨论英语初学者不能正确使用这种语言的许多情况。
I have reached a point in my life where I am supposed to make a decisions of my own.
我已经到了一个应该自己做决定的人生阶段了。

why 的用法

why 指原因,在定语从句中做原因状语,先行词一般为 reason。相当于 for which。但是,reason 作先行词时,若关系词在从句中作主语或宾语时,定语从句要用 that 或 which 引导。
-例句
He couldn't give the teacher a good reason why he was late for school.
他不能给老师一个很好的关于他上学迟到的理由。
The boss doesn't want to hear any reason (that/which) you might give.
老板不想听你可能给出的任何理由。(从句中 that/which 作 give 的宾语,不能用 why)

reason 在定语从句中作先行词,可以用 why 引导,而在同位语从句中,其后通常接 that 引导的同位语从句,解释说明 that 的内容
-例句
The readson that the car broke down caused the accident.
车子坏了这一原因导致了这一事故。

关系词的选择

关系代词和关系副词的选择

对于一个先行词,要想确定是用关系代词还是关系副词,主要是搞清楚关系词在定语从句中做什么成分。
-例句
I will remember the day when I left my home town forever.
我会永远记住我离开家乡的那一天。(when 做状语,相当于 on the day)
I will remember the day that/which we spent together forever.
我会永远记住我们一起度过的那一天。(that/which 做 spent 的宾语)
This is the place where he works.
这是他工作的地方。(where 做状语,相当于 in the place)
This is the place that/which we visited last month.
这是我们上个月参观过的地方。(that/which 做 visited 的宾语)

1. 代替 where, 在定语从句中做地点状语。
-例句

2. 代替 why, 在定语从句中做原因状语。

way 和 time 后定语从句的关系词的选择

1. way 后面的定语从句
如果先行词 way 后面的定语从句缺少宾语,那么用 that, which 或 省略关系词;如果定语从句中缺少方式状语,那么用in wchich, that 或者省略关系词。(能省略的时候省略就对了
-例句
The way (which/that) he explained to us was quite simple.
他向我们解释的那种方法很简单。

若 time 表示“一段时间”时,应用关系副词 when 或 "at/during which" 引导定语从句。

同位语从句和定语从句的关系

被修饰词

同位语从句前的修饰词多为 idea, fact, word, news, hope, evidence, belief, possibility, proposal 等抽象名词;定语从句前的修饰词可以是名词、代词、主句的一部分或整个主句。
-例句

有明确的证据表明,所有感觉中最难阐释的是身体上的疼痛。(同位语从句

同位语从句相当于一个名词,对前面的抽象名词作说明和解释;定语从句相当于一个形容词,对先行词进行修饰或限制。
I have no idea when he was set free.
我不知道他什么时候被放出来的。(同位语从句
I will never forget the day when he was admitted into PKU.
我永远不会忘记他被北京大学录取的那一天。(定语从句

有些引导词如 how, whether, what 可以引导同位语从句,但不能引导定语从句。

我们是否需要它这个问题还没有考虑(同位语从句
It is a question that how he did it.
