2. 关系副词when在定语从句中作　时间状语　 (句1)。
3. 关系副词why在定语从句中作　原因状语　 (句3)。
4. 　“介词+关系代词”　引导的定语从句(句4和句5)。
地点状语
时间状语
原因状语
“介词+关系代词”
1. 关系副词引导的定语从句
当先行词在定语从句中作状语,即定语从句不缺主语、宾语或者表语时,通常要用关系副词引导定语从句。常用的关系副词有where、when、why。关系副词的指代及功能如下:
关系副词 先行词 功能
when 表示时间的名词 时间状语
where 表示地点的名词 地点状语
why reason 原因状语
(1)关系副词where
where引导定语从句时,先行词往往是表示地点的名词(如place、room、house、spot、school、country等),关系副词where在从句中作地点状语,相当于“介词in/at/on…+which”结构。
The stadium where/in which the athletes work out is not far from here.
运动员们锻炼的体育馆离这里不远。
After living in Paris for fifty years he returned to the small town where/in which he grew up as a child. 在巴黎生活了50年后,他回到了儿时成长的那个小镇。
当先行词为situation、case、stage、point、activity、atmosphere等抽象名词,且引导词在定语从句中表示事情发生的情况、阶段等时,常用关系副词where引导。
They have reached the point where they have to separate with each other.
他们已经到了必须分手的地步。
(2)关系副词when
when引导定语从句时,先行词往往是表示时间的名词(如time、day、week、month、year等),关系副词when在从句中作时间状语,相当于“介词in/at/on/during…+which”结构。
I will never forget the day when/on which I first saw you.
我永远不会忘记第一次见到你的那天。
I’ll never forget the time when I was trapped in a burning house. 我永远不会忘记我被困在失火的房子里的时候。
(3)关系副词why
why引导定语从句时,先行词常为reason,关系副词why在从句中作原因状语,相当于“for+which”结构。
Do you know the reason why/for which she is under great stress
你知道她压力很大的原因吗
(4)关系代词与关系副词的用法区别
选用关系代词还是关系副词,归根结底要看定语从句缺什么成分。如果缺的是主语、宾语、表语或定语,就用关系代词;如果缺的是状语,就用关系副词。
①先行词表示时间
I will never forget the days when we had a good time on the beach.(从句缺状语,故用when)
我永远不会忘记我们在海滩上玩得很开心的那些日子。
I will never forget the days (which/that) we spent together on the beach.(从句缺宾语,故用which或that,也可省略)
我永远不会忘记我们一起在海滩上度过的日子。
②先行词表示地
The mountain village where I used to stay for one night last year has taken on a new look.(从句缺状语,故用where)
我去年住过一晚的那个山村现在面貌焕然一新。
The mountain village (which/that) we paid a visit to last year has taken on a new look.(从句缺宾语,故用which或that,也可省略)
我们去年参观过的那个山村现在面貌焕然一新。
③先行词是reason
The reason why he was late for work was that he had an accident on the way.(从句缺状语,故用why)
他上班迟到的原因是他在路上出了事故。
The reason (which/that) he gave for his being late for work was that he had an accident on the way.(从句缺宾语,故用which或that,也可省略)
他给出的上班迟到的理由是他在路上出了事故。
2. “介词+关系代词”引导的定语从句
(1)常用的关系代词
关系代词作介词的宾语时,为了使关系代词与先行词的关系更加紧凑,可以将从句中的介词提到关系代词前,形成“介词+关系代词”的结构。该结构中的关系代词可用which(指物)或whom(指人)。
(2)介词的选用
可以遵循“一先二动三意义”的原则。
①“一先”——依据与先行词搭配的具体意义而定。
I’ll never forget the farm on which I spent my childhood in the country.(on the farm意为“在农场上”)
我永远不会忘记我在乡村度过童年时光的那个农场。
This is the gun with which the hunter shot the antelope.(shot with the gun意为“用枪射击”)
这是猎人射杀羚羊用的那支枪。
②“二动”——依据定语从句中动词或形容词等所需要的某种习惯搭配来确定。
He brought the result with which the boss was satisfied.(be satisfied with意为“对……满意”)
他带来了令老板满意的结果。
It is the grammar rules of which I am not sure.(be sure of sth意为“对某事有把握”)
这是我不确定的语法规则。
③“三意义”——根据从句表达的意义和先行词的逻辑关系来确定。
This is the pilot by whom my son was saved.
这就是救了我儿子的那位飞行员。
This is my pair of glasses, without which I cannot see clearly.
这是我的一副眼镜,没有它我就看不清楚。
有些“动词+介词”短语如look for、look after、 call on等,如果介词提前将会失去动词短语的意义,所以不可把它们的介词置于关系代词前。
Is this the brochure which she is looking for
这就是她正在找的那本册子吗
The old man whom I am looking after is better.
我照顾的那位老人已经好多了。
(3)“名词/数词/代词等+介词of+关系代词”结构
有时“介词+关系代词”前还会有名词、数词、代词等,表示部分、整体、数量等概念。
The river, the banks of which are covered with trees, flows to the sea.
这条河流入大海,河的两岸都是树。
In the class there are 50 students, most of whom are very hard-working.
这个班里有50个学生,其中大多数都很勤奋。
