复合句之定语从句
供稿：hz-xin.com 日期：2024-04-28
限制性定语从句对先行词起修饰限制作用; 非限制性定语从句对先行词起补充说明作用。在非限制性定语从句中, 先行词与定语从句往往由 逗号 隔开。非限制性定语从句相当于并列分句、状语从句等。
He has two sons, who work in the same company.(He has only two sons.)
他有两个儿子, 他们在同一家公司上班。
He has two sons who work in the same company. (Perhaps he has more than two sons.)
他有两个儿子在同一家公司上班。
He failed in the match, which was a great pity. (非限制性定语从句, 先行词为前面的句子) (=He failed in the match, and it was a great pity.)
他在比赛中失败了, 这真令人遗憾。

我认为他不会来看我了, 这使我伤心。

[20] There is no simple answer, as is often the case in science.
(一)当关系词在定语从句中作状语时, 要用关系副词。其中 when = 表时间的介词(如: in, at, on, during 等) + which; where = 表地点的介词(如: in, at, on, under 等) + which; why = 表原因的介词(如: for) + which。
I still remember the day when I first came to Beijing.(when= on which)

Can you tell me the office where he works? (where=in which)
你能告诉我他工作的办公室吗?
Do you know the reason why he is absent? (why=for which)
你知道他缺席的原因吗?
此外, 当先行词为 situation, case, stage, point 等, 且关系词在定语从句中作状语时, 也要用关系副词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。
[21] (2013 江西, 33) He wrote a letter where he explained what had happened in the accident.
[22]Sales director is a position where communication ability is just as important as sales skills.
(二)where/ when = 介词 + 关系代词(which), 有时为表达清楚, 还可以在关系副词where/when 前加介词 from/to 等。
China is the birthplace of kites, from where kite flying spreads to Japan, Korea, Thailand and India.
中国是风筝的发源地吧,从这里放风筝传到了日本、朝鲜、泰国和印度。
(三)关系副词 when, where 可用于非限制性定语从句中, 而关系副词why 不可以。
1. 当先行词是way(意为“方式, 方法”)时, 引导定语从句的关系词有下列三种形式。
What surprised me was not what he said but the way in which he said it.
What surprised me was not what he said but the way that he said it.
What surprised me was not what he said but the way (不填) he said it.
让我吃惊的不是他说的话, 而是他说话的方式。
注意下面两个句子中关系词的不同, 试比较:
The way that he explained to us was quite simple.
The way which he explained to us was quite simple.
The way (不填) he explained to us was quite simple.
他向我们解释的那种方法很简单。
The way that he explained the sentence to us was not difficult to understand.
The way in which he explained the sentence to us was not difficult to understand.
The way (不填) he explained the sentence to us was not difficult to understand.
他向我们解释句子的那种方式不难理解。
2. 先行词是 time, 若 time 作“次数”讲时, 应用关系代词 that 引导定语从句, that 可省略;若 time 作“ 一段时间” 讲且作状语时, 应用关系副词 when 或介词at/during + which 引导定语从句。
This is the second time ( that ) the President has visited the country. 这是总统第二次访问这个国家了。
This was at a time when/during which there were no radios, no telephones or no TV sets.
这是在一个没有收音机、没有电话, 也没有电视的时期。
题组训练 用适当的关系代词、关系副词或“介词+关系代词”填空
[23]I don't like the way that/in which he laughs at her.
[24]This is the second time that I have been here.
[25]Can you still remember the time that/which we spent together in our childhood?
[26]The first time that he saw her, he fell in love with her.
引导定语从句的关系代词和关系副词除了起连接主句和从句的作用外, 它们还有一个最重要的作用, 那就是它们分别在定语从句中作成分。具体地说, 关系代词在定语从句中作主语、宾语、定语或表语, 而关系副词在定语从句中作状语。因此, 在选择关系词时, 最重要的是分析一下定语从句中所缺的成分, 若从句中缺主语、宾语、定语或表语, 那么需用关系代词;若从句中缺状语, 那么需用关系副词。
试比较下面的句子:
(1)Do you still remember the days ( that/which ) we spent in Qingdao? 你还记得我们在青岛度过的日子吗?
(2)Do you still remember the days when we spent the summer holidays in Qingdao?
你还记得我们在青岛过暑假的日子吗?
在句(1)中, 定语从句中缺宾语, 因此可用关系代词 that/which 来引导从句, 也可省略;
在句(2)中, 定语从句中缺时间状语, 因此需用关系副词when 来引导从句。
[27]I want to know the date when you were born.
[28]I have forgotten the date that/which you told me.
[29]Do you know the reason why he is absent today?
[30]That is the reason that/which I want to know.
[31] (2013 北京, 27)Many countries are now setting up national parks where animals and plants can be protected.
[32]This is the factory that/which his father built.
He has two sons, who work in the same company.(He has only two sons.)
他有两个儿子, 他们在同一家公司上班。
He has two sons who work in the same company. (Perhaps he has more than two sons.)
他有两个儿子在同一家公司上班。
He failed in the match, which was a great pity. (非限制性定语从句, 先行词为前面的句子) (=He failed in the match, and it was a great pity.)
他在比赛中失败了, 这真令人遗憾。

Here is the English grammar book which, as I've told you , will help you improve your English.
这就是我告诉过你的那本英语语法书, 它能帮你提高英语。
4)先行词本身就是 that 时, 只用 which, 不用 that。
What's that which flashed through the sky just now?
刚才在天空中一闪而过的是什么?
[11]I refuse to accept the blame for something that was someone else's fault.
[12]Whenever I met her, which was fairly often, she greeted me with a sweet smile.
[13]All the presents that your friends gave you on your birthday should be put away.
[14]This is the very book that I have been looking for.
[15]He was late for the opening ceremony, which was very surprising to me.
2. 关系代词as 和which 的区别
as 和 which 都可以引导非限制性定语从句, 先行词为整个主句或主句中的一部分内容, 先行词在定语从句中作主语、宾语或表语, as 与which 均不可省略, 有时两者可以互换。
He married her, as/which was natural.
他跟她结婚了, 这是很自然的事。
(1)下列情况通常只用 as 而不用 which:
1)当定语从句置于主句前面时, 用 as 不用 which。
As you see, the Chinese people are hard-working.(定语从句在句首)你知道, 中国人民是勤劳的。
注意下面句子的多种表达方法:
众所周知, 月球每月绕地球转一圈。
As is known to everybody , the moon travels round the earth once every month.
The moon travels round the earth once every month, as/which is known to everybody .
It is known to everybody that the moon travels round the earth once every month.
What is known to everybody is that the moon travels round the earth once every month.
(后两句属名词性从句范畴)
[16] What is known to us all is that China has the largest population in the world.
[17] It is known to us all that China has the largest population in the world.
[18] As is known to us all, China has the largest population in the world.
2)先行词作主语且定语从句为被动语态时, 通常用 as 不用 which, 从句谓语通常为: be known, be said, be reported, be announced, be mentioned 等。如果从句是主动语态, 一般用 which 作主语。
She has been absent again, as is expected.
她又缺席了, 这在预料之中。
Tom has made rapid progress, which makes me very happy.
汤姆进步很快, 这使我很高兴。
另外, as 常用在下列习惯用语中: as(it)seems likely, as(it) often happens, as(it) was printed out, as(it) was said earlier, as I remember(it), as I understand(it), as(it) appears, as is often the case, as anybody can see, as we have expected。
Jack has won the first prize, as it often happens.
像往常一样, 杰克得了一等奖。
She has read widely in Romantic Literature, as it appears from her essay.
她广泛涉猎了浪漫主义文学, 这从她的文章中可以看出来。
(2)下列情况通常用 which 而不用 as:
1)关系代词代替前面主句中的宾语从句或定语从句的谓语动词后有复合宾语时。
I don't think that he will come to see me, which makes me sad.
我认为他不会来看我了, 这使我伤心。
2)which 一般用作实义动词的主语, 这时它所引导的从句与主句之间存在着逻辑上的因果关系时。
Tom was late for school again and again, which made his teacher very angry.
汤姆一次又一次上学迟到, 这使得他的老师很生气。
3)当非限制性定语从句是否定句时。
He pretended not to know me, which I didn't understand.
他假装不认识我, 我真不明白。
4)非限制性定语从句中的be 动词不能省略时, 用which;反之用as。
Jane told me she won the match, which was a lie.
简告诉我她赢了这场比赛, 这是谎话。(was 不可省略)
As (was) planned, we met at the airport.
按照计划, 我们在机场相见了。(was 可省略)
[19] A lot of language learning, as has been discovered, is happening in the first year of life, so parents should talk much to their children during that period.
[20] There is no simple answer, as is often the case in science.
(一)当关系词在定语从句中作状语时, 要用关系副词。其中 when = 表时间的介词(如: in, at, on, during 等) + which; where = 表地点的介词(如: in, at, on, under 等) + which; why = 表原因的介词(如: for) + which。
I still remember the day when I first came to Beijing.(when= on which)
我还记得第一次来北京的那一天。
Can you tell me the office where he works? (where=in which)
你能告诉我他工作的办公室吗?
Do you know the reason why he is absent? (why=for which)
你知道他缺席的原因吗?
此外, 当先行词为 situation, case, stage, point 等, 且关系词在定语从句中作状语时, 也要用关系副词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。
[21] (2013 江西, 33) He wrote a letter where he explained what had happened in the accident.
[22]Sales director is a position where communication ability is just as important as sales skills.
(二)where/ when = 介词 + 关系代词(which), 有时为表达清楚, 还可以在关系副词where/when 前加介词 from/to 等。
China is the birthplace of kites, from where kite flying spreads to Japan, Korea, Thailand and India.
中国是风筝的发源地吧,从这里放风筝传到了日本、朝鲜、泰国和印度。
(三)关系副词 when, where 可用于非限制性定语从句中, 而关系副词why 不可以。
1. 当先行词是way(意为“方式, 方法”)时, 引导定语从句的关系词有下列三种形式。
What surprised me was not what he said but the way in which he said it.
What surprised me was not what he said but the way that he said it.
What surprised me was not what he said but the way (不填) he said it.
让我吃惊的不是他说的话, 而是他说话的方式。
注意下面两个句子中关系词的不同, 试比较:
The way that he explained to us was quite simple.
The way which he explained to us was quite simple.
The way (不填) he explained to us was quite simple.
他向我们解释的那种方法很简单。
The way that he explained the sentence to us was not difficult to understand.
The way in which he explained the sentence to us was not difficult to understand.
The way (不填) he explained the sentence to us was not difficult to understand.
他向我们解释句子的那种方式不难理解。
2. 先行词是 time, 若 time 作“次数”讲时, 应用关系代词 that 引导定语从句, that 可省略;若 time 作“ 一段时间” 讲且作状语时, 应用关系副词 when 或介词at/during + which 引导定语从句。
This is the second time ( that ) the President has visited the country. 这是总统第二次访问这个国家了。
This was at a time when/during which there were no radios, no telephones or no TV sets.
这是在一个没有收音机、没有电话, 也没有电视的时期。
题组训练 用适当的关系代词、关系副词或“介词+关系代词”填空
[23]I don't like the way that/in which he laughs at her.
[24]This is the second time that I have been here.
[25]Can you still remember the time that/which we spent together in our childhood?
[26]The first time that he saw her, he fell in love with her.
引导定语从句的关系代词和关系副词除了起连接主句和从句的作用外, 它们还有一个最重要的作用, 那就是它们分别在定语从句中作成分。具体地说, 关系代词在定语从句中作主语、宾语、定语或表语, 而关系副词在定语从句中作状语。因此, 在选择关系词时, 最重要的是分析一下定语从句中所缺的成分, 若从句中缺主语、宾语、定语或表语, 那么需用关系代词;若从句中缺状语, 那么需用关系副词。
试比较下面的句子:
(1)Do you still remember the days ( that/which ) we spent in Qingdao? 你还记得我们在青岛度过的日子吗?
(2)Do you still remember the days when we spent the summer holidays in Qingdao?
你还记得我们在青岛过暑假的日子吗?
在句(1)中, 定语从句中缺宾语, 因此可用关系代词 that/which 来引导从句, 也可省略;
在句(2)中, 定语从句中缺时间状语, 因此需用关系副词when 来引导从句。
[27]I want to know the date when you were born.
[28]I have forgotten the date that/which you told me.
[29]Do you know the reason why he is absent today?
[30]That is the reason that/which I want to know.
[31] (2013 北京, 27)Many countries are now setting up national parks where animals and plants can be protected.
[32]This is the factory that/which his father built.
