如何区分状语从句 定语从句 名词性从句
请着中讲解做选择题是如何区分
请着中讲解做选择题是如何区分
19.1 地点状语从句
地点状语从句通常由where, wherever 引导.
Where I live there are plenty of trees.
我住的地方树很多.
Wherever I am I will be thinking of you.
不管我在哪里我都会想到你.
19.2 方式状语从句
方式状语从句通常由as, (just) as…so…, as if, as though引导.
1） as, (just) as…so…引导的方式状语从句通常位于主句后,但在(just) as…so…结构中位于句首,这时as从句带有比喻的含义,意思是"正如…","就像",多用于正式文体,例如：
Always do to the others as you would be done by.
你希望人家怎样待你,你就要怎样待人.
As water is to fish, so air is to man.
我们离不开空气,犹如鱼儿离不开水.
Just as we sweep our rooms, so we should sweep backward ideas from our minds.
正如打扫房屋一样,我们也要扫除我们头脑中落后的东西.
2） as if, as though
两者的意义和用法相同,引出的状语从句谓语多用虚拟语气,表示与事实相反,有时也用陈述语气,表示所说情况是事实或实现的可能性较大.汉译常作"仿佛……似的","好像……似的",例如：
They completely ignore these facts as if (as though) they never existed.
他们完全忽略了这些事实,就仿佛它不存在似的.（与事实相反,谓语用虚拟语气.）
He looks as if (as though) he had been hit by lighting.
他那样子就像被雷击了似的.（与事实相反,谓语用虚拟语气.）
It looks as if the weather may pick up very soon.
看来天气很快就会好起来.（实现的可能性较大,谓语用陈述语气.）
说明：as if / as though也可以引导一个分词短语、不定式短语或无动词短语,例如：
He stared at me as if seeing me for first time.
他目不转睛地看着我,就像第一次看见我似的.
He cleared his throat as if to say something.
他清了清嗓子,像要说什么似的.
The waves dashed on the rocks as if in anger.
波涛冲击着岩石,好像很愤怒.
19.3 原因状语从句
比较：because, since, as和for
1） because语势最强,用来说明人所不知的原因,回答why提出的问题.当原因是显而易见的或已为人们所知,就用as或 since.
I didn't go, because I was afraid.
Since /As the weather is so bad, we have to delay our journey.
2） 由because引导的从句如果放在句末,且前面有逗 号,则可以用for来代替.但如果不是说明直接原因,而是多种情况加以推断,就只能用for.
He is absent today, because / for he is ill.
He must be ill, for he is absent today.
19.4 目的状语从句
表示目的状语的从句可以由that, so that, in order that, lest, for fear that, in case等词引导,例如：
You must speak louder so that /in order that you can be heard by all.
He wrote the name down for fear that(lest) he should forget it.
Better take more clothes in case the weather is cold.
19.5 结果状语从句
结果状语从句常由so… that 或 such…that引导,掌握这两个句型,首先要了解so 和 such与其后的词的搭配规律.
比较：so和 such
其规律由so与such的不同词性决定.such 是形容词,修饰名词或名词词组,so 是副词,只能修饰形容词或副词. so 还可与表示数量的形容词many, few, much, little连用,形成固定搭配.
so foolish such a fool
so nice a flower such a nice flower
so many / few flowers such nice flowers
so much / little money. such rapid progress
so many people such a lot of people
（ so many 已成固定搭配,a lot of 虽相当于 many,但 a lot of 为名词性的,只能用such搭配.）
so…that与such…that之间的转换既为 so与such之间的转换.
The boy is so young that he can't go to school.
He is such a young boy that he can't go to school
19.6 条件状语从句
连接词主要有 if, unless, as/so long as, on condition that 等..
if 引导的条件句有真实条件句和非真实条件句两种.非真实条件句已在虚拟语气中阐述.
unless = if not.
Let's go out for a walk unless you are too tired.
If you are not too tied, let's go out for a walk.
典型例题
You will be late ___ you leave immediately.
A. unless B. until C. if D. or
答案A. 句意：除非你立即走,否则你就回迟到的.可转化为 If you dong leave immediately, you will be late. B、D句意不对,or表转折,句子如为 You leave immediately or you will be late.
19.7 让步状语从句
though, although
注意： 当有though, although时,后面的从句不能有but,但是 though 和yet可连用
Although it's raining, they are still working in the field.
虽然在下雨,但他们仍在地里干活.
He is very old, but he still works very hard.
虽然他很老,但仍然努力地工作.
Though the sore be healed, yet a scar may remain.
伤口虽愈合,但伤疤留下了. （谚语）
典型例题
1） ___she is young, she knows quite a lot.
A. When B. However C. Although D. Unless
答案：C.意为虽然她很年轻,却知道许多.
2) as, though 引导的倒装句
as / though引导的让步从句必须表语或状语提前（形容词、副词、分词、实义动词提前）.
Child as /though he was, he knew what was the right thing to do.
= Though he was a small child, he knew what was the right thing to do.
注意： a. 句首名词不能带任何冠词.
b. 句首是实义动词,其他助动词放在主语后.如果实义动词有宾语和状语,随实义动词一起放在主语之前.
Try hard as he will, he never seems able to do the work satisfactorily.
= Though he tries hard, he never seems…
虽然他尽了努力,但他的工作总做的不尽人意.
3) ever if, even though. 即使
We'll make a trip even though the weather is bad.
4) whether…or- 不管……都
Whether you believe it or not, it is true.
5) "no matter +疑问词" 或"疑问词+后缀ever"
No matter what happened, he would not mind.
Whatever happened, he would not mind.
替换：no matter what = whatever
no matter who = whoever
no matter when = whenever
no matter where = wherever
no matter which = whichever
no matter how = however
注意：no matter 不能引导主语从句和宾语从句.
（错）No matter what you say is of no use now.
（对）Whatever you say is of no use now.
你现在说什么也没用了.(Whatever you say是主语从句)
（错）Prisoners have to eat no matter what they're given,
（对）Prisoners have to eat whatever they're given. 囚犯们只能给什么吃什么.
19.8 比较while, when, as
1）as, when 引导短暂性动作的动词.
Just as / Just when / When I stopped my car, a man came up to me.
2）当从句的动作发生于主句动作之前,只能用when 引导这个从句,不可用as 或 while.
When you have finished your work, you may have a rest.
3）从句表示"随时间推移"连词能用as,不用when 或while.
As the day went on, the weather got worse.
日子一天天过去,天气越变越坏.
19.9 比较until和till
此两个连词意义相同.肯定形式表示的意思是"做某事直至某时",动词必须是延续性的.否定形式表达的意思是"直至某时才做某事".动词为延续性或非延续性都可 以. 正确使用这两个连词的关键之一就在于判断句中的动词该用肯定式还是否定式.
肯定句：
I slept until midnight. 我一直睡到半夜时醒了.
Wait till I call you. 等着我叫你.
（在肯定句中可用before代替 Let's get in the wheat before the sun sets.）
否定句：
She didn't arrive until 6 o'clock.
她直到6点才到.
Don't get off the bus until it has stopped.
公共汽车停稳后再下车.
I didn't manage to do it until you had explained how. 直到你教我后,我才会做.
1)Until可用于句首,而till通常不用于句首.
Until you told me, I had heard nothing of what happened.
直到你告诉我以前,出了什么事我一点也不知道.
2)Until when 疑问句中,until要放在句首.
---Until when are you staying? 你呆到什么时候?
--- Until next Monday. 呆到下周一.
注意：否定句可用另外两种句式表示.
(1）Not until …在句首,主句用倒装.
Not until the early years of the 19th century did man know what heat is.
直到19 世纪初,人类才知道热能是什么.
Not until I began to work did I realize how much time I had wasted.
直到我开始工作,我才认识到了我已蹉跎了几多岁月.
(2) It is not until… that…
19.10 表示"一…就…"的结构
hardly/scarcely…when/before, no sooner…than 和as soon as都可以表示"一…就…"的意思,例：
I had hardly / scarcely got home when it began to rain.
I had no sooner got home than it began to rain.
As soon as I got home, it began to rain.
注意：如果hardly, scarcely 或no sooner置于句首,句子必须用倒装结构：
Hardly / Scarcely had I got home when it began to rain.
No sooner had I got home than it began to rain.
18.1 关系代词引导的定语从句
关系代词所代替的先行词是人或物的名词或代词,并在句中充当主语、宾语、定语等成分.关系代词在定语从句中作主语时,从句谓语动词的人称和数要和先行词保持一致.
1）who, whom, that
这些词代替的先行词是人的名词或代词,在从句中所起作用如下：
Is he the man who/that wants to see you?
他就是你想见的人吗?（who/that在从句中作主语）
He is the man whom/ that I saw yesterday.
他就是我昨天见的那个人.（whom/that在从句中作宾语）
2) Whose 用来指人或物,(只用作定语, 若指物,它还可以同of which互换）, 例如：
They rushed over to help the man whose car had broken down. 那人车坏了,大家都跑过去帮忙.
Please pass me the book whose (of which) cover is green. 请递给我那本绿皮的书.
3）which, that
它们所代替的先行词是事物的名词或代词,在从句中可作主语、宾语等,例如：
A prosperity which / that had never been seen before appears in the countryside. 农村出现了前所未有的繁荣.（which / that在句中作宾语）
The package (which / that) you are carrying is about to come unwrapped. 你拿的包快散了.(which / that在句中作宾语）
18.2 关系副词引导的定语从句
关系副词可代替的先行词是时间、地点或理由的名词,在从句中作状语.
1）when, where, why
关系副词when, where, why的含义相当于"介词+ which"结构,因此常常和"介词+ which"结构交替使用,例如：
There are occasions when (on which) one must yield. 任何人都有不得不屈服的时候.
Beijing is the place where (in which) I was born. 北京是我的出生地.
Is this the reason why (for which) he refused our offer? 这就是他拒绝我们帮助他的理由吗?
2）that代替关系副词
that可以用于表示时间、地点、方式、理由的名词后取代when, where, why和"介词+ which"引导的定语从句,在口语中that常被省略,例如：
His father died the year (that / when / in which) he was born. 他父亲在他出生那年逝世了.
He is unlikely to find the place (that / where / in which) he lived forty years ago. 他不大可能找到他四十年前居住过的地方.
18.3 判断关系代词与关系副词
方法一： 用关系代词,还是关系副词完全取决于从句中的谓语动词.及物动词后面无宾语,就必须要求用关系代词；而不及物动词则要求用关系副词.例如：
This is the mountain village where I stayed last year.
I'll never forget the days when I worked together with you.
判断改错（注：先显示题,再显示答案,横线；用不同的颜色表示出.）
（错） This is the mountain village where I visited last year.
（错） I will never forget the days when I spent in the countryside.
（对） This is the mountain village (which) I visited last year.
（对） I'll never forget the days (which) I spent in the countryside.
习惯上总把表地点或时间的名词与关系副词 where, when联系在一起.此两题错在关系词的误用上.
方法二： 准确判断先行词在定语从句中的成分(主、谓、宾、定、状),也能正确选择出关系代词/关系副词.
例1. Is this museum ___ you visited a few days age?
A. where B. that C. on which D. the one
例2. Is this the museum ____ the exhibition was held.
A. where B. that C. on which D. the one
答案：例1 D,例2 A
例1变为肯定句： This museum is ___ you visited a few days ago.
例2变为肯定句： This is the museum ___ the exhibition was held.
在句1中,所缺部分为宾语,而where, that, on which都不能起到宾语的作用,只有the one既做了主句的表语,又可做从句的宾语,可以省略关系代词,所以应选D.
而句2中, 主、谓、宾俱全,从句部分为句子的状语表地点,既可用副词where,又因 in the museum词组,可用介词in + which 引导地点状语.而此题中,介词on 用的不对,所以选A.
关系词的选择依据在从句中所做的成分,先行词在从句中做主、定、宾语时,选择关系代词 (who, whom, that, which, whose)； 先行词在从句中做状语时,应选择关系副词 ( where 地点状语,when 时间状语,why 原因状语) .
18.4 限制性和非限制性定语从句
1) 定语从句有限制性和非限制性两种.限制性定语从句是先行词不可缺少的部分,去掉它主句意思往往不明确；非限制性定语从句是先行词的附加说明,去掉了也不会影响主句的意思,它与主句之间通常用逗号分开,例如：
This is the house which we bought last month. 这是我们上个月买的那幢房子.（限制性）
The house, which we bought last month, is very nice.这幢房子很漂亮,是我们上个月买的.（非限制性）
2) 当先行词是专有名词或物主代词和指示代词所修饰时,其后的定语从句通常是非限制性的,例如：
Charles Smith, who was my former teacher, retired last year. 查理·史密斯去年退休了,他曾经是我的老师.
My house, which I bought last year, has got a lovely garden. 我去年买的的那幢房子带着个漂亮的花园.
This novel, which I have read three times, is very touching. 这本小说很动人,我已经读了三遍.
3) 非限制性定语从句还能将整个主句作为先行词, 对其进行修饰, 这时从句谓语动词要用第三人称单数,例如：
He seems not to have grasped what I meant, which greatly upsets me. 他似乎没抓住我的意思,这使我心烦.
Liquid water changes to vapor, which is called evaporation. 液态水变为蒸汽,这就叫做蒸发.
说明：关系代词that和关系副词why不能引导非限制性定语从句.
18.5 介词+关系词
1）介词后面的关系词不能省略.
2）that前不能有介词.
3） 某些在从句中充当时间,地点或原因状语的"介词+关系词"结构可以同关系副词when 和where 互换.
This is the house in which I lived two years ago.
This is the house where I lived two years ago.
Do you remember the day on which you joined our club?
Do you remember the day when you joined our club?
18.5 介词+关系词
1）介词后面的关系词不能省略.
2）that前不能有介词.
3） 某些在从句中充当时间,地点或原因状语的"介词+关系词"结构可以同关系副词when 和where 互换.
This is the house in which I lived two years ago.
This is the house where I lived two years ago.
Do you remember the day on which you joined our club?
Do you remember the day when you joined our club?
18.5 介词+关系词
1）介词后面的关系词不能省略.
2）that前不能有介词.
3） 某些在从句中充当时间,地点或原因状语的"介词+关系词"结构可以同关系副词when 和where 互换.
This is the house in which I lived two years ago.
This is the house where I lived two years ago.
Do you remember the day on which you joined our club?
Do you remember the day when you joined our club?
地点状语从句通常由where, wherever 引导.
Where I live there are plenty of trees.
我住的地方树很多.
Wherever I am I will be thinking of you.
不管我在哪里我都会想到你.
19.2 方式状语从句
方式状语从句通常由as, (just) as…so…, as if, as though引导.
1） as, (just) as…so…引导的方式状语从句通常位于主句后,但在(just) as…so…结构中位于句首,这时as从句带有比喻的含义,意思是"正如…","就像",多用于正式文体,例如：
Always do to the others as you would be done by.
你希望人家怎样待你,你就要怎样待人.
As water is to fish, so air is to man.
我们离不开空气,犹如鱼儿离不开水.
Just as we sweep our rooms, so we should sweep backward ideas from our minds.
正如打扫房屋一样,我们也要扫除我们头脑中落后的东西.
2） as if, as though
两者的意义和用法相同,引出的状语从句谓语多用虚拟语气,表示与事实相反,有时也用陈述语气,表示所说情况是事实或实现的可能性较大.汉译常作"仿佛……似的","好像……似的",例如：
They completely ignore these facts as if (as though) they never existed.
他们完全忽略了这些事实,就仿佛它不存在似的.（与事实相反,谓语用虚拟语气.）
He looks as if (as though) he had been hit by lighting.
他那样子就像被雷击了似的.（与事实相反,谓语用虚拟语气.）
It looks as if the weather may pick up very soon.
看来天气很快就会好起来.（实现的可能性较大,谓语用陈述语气.）

He stared at me as if seeing me for first time.
他目不转睛地看着我,就像第一次看见我似的.
He cleared his throat as if to say something.
他清了清嗓子,像要说什么似的.
The waves dashed on the rocks as if in anger.
波涛冲击着岩石,好像很愤怒.
19.3 原因状语从句
比较：because, since, as和for
1） because语势最强,用来说明人所不知的原因,回答why提出的问题.当原因是显而易见的或已为人们所知,就用as或 since.
I didn't go, because I was afraid.
Since /As the weather is so bad, we have to delay our journey.
2） 由because引导的从句如果放在句末,且前面有逗 号,则可以用for来代替.但如果不是说明直接原因,而是多种情况加以推断,就只能用for.
He is absent today, because / for he is ill.
He must be ill, for he is absent today.
19.4 目的状语从句
表示目的状语的从句可以由that, so that, in order that, lest, for fear that, in case等词引导,例如：
You must speak louder so that /in order that you can be heard by all.
He wrote the name down for fear that(lest) he should forget it.
Better take more clothes in case the weather is cold.
19.5 结果状语从句
结果状语从句常由so… that 或 such…that引导,掌握这两个句型,首先要了解so 和 such与其后的词的搭配规律.
比较：so和 such
其规律由so与such的不同词性决定.such 是形容词,修饰名词或名词词组,so 是副词,只能修饰形容词或副词. so 还可与表示数量的形容词many, few, much, little连用,形成固定搭配.
so foolish such a fool
so nice a flower such a nice flower
so many / few flowers such nice flowers
so much / little money. such rapid progress
so many people such a lot of people
（ so many 已成固定搭配,a lot of 虽相当于 many,但 a lot of 为名词性的,只能用such搭配.）
so…that与such…that之间的转换既为 so与such之间的转换.
The boy is so young that he can't go to school.
He is such a young boy that he can't go to school
19.6 条件状语从句
连接词主要有 if, unless, as/so long as, on condition that 等..

If you are not too tied, let's go out for a walk.
典型例题
You will be late ___ you leave immediately.
A. unless B. until C. if D. or
答案A. 句意：除非你立即走,否则你就回迟到的.可转化为 If you dong leave immediately, you will be late. B、D句意不对,or表转折,句子如为 You leave immediately or you will be late.
19.7 让步状语从句
though, although
注意： 当有though, although时,后面的从句不能有but,但是 though 和yet可连用

A. When B. However C. Although D. Unless
答案：C.意为虽然她很年轻,却知道许多.
2) as, though 引导的倒装句
as / though引导的让步从句必须表语或状语提前（形容词、副词、分词、实义动词提前）.
Child as /though he was, he knew what was the right thing to do.
= Though he was a small child, he knew what was the right thing to do.
注意： a. 句首名词不能带任何冠词.
b. 句首是实义动词,其他助动词放在主语后.如果实义动词有宾语和状语,随实义动词一起放在主语之前.
Try hard as he will, he never seems able to do the work satisfactorily.
= Though he tries hard, he never seems…
虽然他尽了努力,但他的工作总做的不尽人意.
3) ever if, even though. 即使
We'll make a trip even though the weather is bad.
4) whether…or- 不管……都
Whether you believe it or not, it is true.
5) "no matter +疑问词" 或"疑问词+后缀ever"
No matter what happened, he would not mind.
Whatever happened, he would not mind.
替换：no matter what = whatever
no matter who = whoever
no matter when = whenever
no matter where = wherever
no matter which = whichever
no matter how = however
注意：no matter 不能引导主语从句和宾语从句.
（错）No matter what you say is of no use now.
（对）Whatever you say is of no use now.
你现在说什么也没用了.(Whatever you say是主语从句)
（错）Prisoners have to eat no matter what they're given,

3）从句表示"随时间推移"连词能用as,不用when 或while.
As the day went on, the weather got worse.
日子一天天过去,天气越变越坏.
19.9 比较until和till
此两个连词意义相同.肯定形式表示的意思是"做某事直至某时",动词必须是延续性的.否定形式表达的意思是"直至某时才做某事".动词为延续性或非延续性都可 以. 正确使用这两个连词的关键之一就在于判断句中的动词该用肯定式还是否定式.
肯定句：
I slept until midnight. 我一直睡到半夜时醒了.
Wait till I call you. 等着我叫你.
（在肯定句中可用before代替 Let's get in the wheat before the sun sets.）

Until you told me, I had heard nothing of what happened.
直到你告诉我以前,出了什么事我一点也不知道.
2)Until when 疑问句中,until要放在句首.
---Until when are you staying? 你呆到什么时候?

直到19 世纪初,人类才知道热能是什么.
Not until I began to work did I realize how much time I had wasted.
直到我开始工作,我才认识到了我已蹉跎了几多岁月.
(2) It is not until… that…
19.10 表示"一…就…"的结构
hardly/scarcely…when/before, no sooner…than 和as soon as都可以表示"一…就…"的意思,例：
I had hardly / scarcely got home when it began to rain.
I had no sooner got home than it began to rain.
As soon as I got home, it began to rain.
注意：如果hardly, scarcely 或no sooner置于句首,句子必须用倒装结构：
Hardly / Scarcely had I got home when it began to rain.
No sooner had I got home than it began to rain.
18.1 关系代词引导的定语从句
关系代词所代替的先行词是人或物的名词或代词,并在句中充当主语、宾语、定语等成分.关系代词在定语从句中作主语时,从句谓语动词的人称和数要和先行词保持一致.
1）who, whom, that
这些词代替的先行词是人的名词或代词,在从句中所起作用如下：
Is he the man who/that wants to see you?
他就是你想见的人吗?（who/that在从句中作主语）
He is the man whom/ that I saw yesterday.
他就是我昨天见的那个人.（whom/that在从句中作宾语）
2) Whose 用来指人或物,(只用作定语, 若指物,它还可以同of which互换）, 例如：
They rushed over to help the man whose car had broken down. 那人车坏了,大家都跑过去帮忙.
Please pass me the book whose (of which) cover is green. 请递给我那本绿皮的书.
3）which, that
它们所代替的先行词是事物的名词或代词,在从句中可作主语、宾语等,例如：
A prosperity which / that had never been seen before appears in the countryside. 农村出现了前所未有的繁荣.（which / that在句中作宾语）
The package (which / that) you are carrying is about to come unwrapped. 你拿的包快散了.(which / that在句中作宾语）
18.2 关系副词引导的定语从句
关系副词可代替的先行词是时间、地点或理由的名词,在从句中作状语.
1）when, where, why
关系副词when, where, why的含义相当于"介词+ which"结构,因此常常和"介词+ which"结构交替使用,例如：
There are occasions when (on which) one must yield. 任何人都有不得不屈服的时候.
Beijing is the place where (in which) I was born. 北京是我的出生地.
Is this the reason why (for which) he refused our offer? 这就是他拒绝我们帮助他的理由吗?
2）that代替关系副词
that可以用于表示时间、地点、方式、理由的名词后取代when, where, why和"介词+ which"引导的定语从句,在口语中that常被省略,例如：
His father died the year (that / when / in which) he was born. 他父亲在他出生那年逝世了.
He is unlikely to find the place (that / where / in which) he lived forty years ago. 他不大可能找到他四十年前居住过的地方.
18.3 判断关系代词与关系副词
方法一： 用关系代词,还是关系副词完全取决于从句中的谓语动词.及物动词后面无宾语,就必须要求用关系代词；而不及物动词则要求用关系副词.例如：
This is the mountain village where I stayed last year.
I'll never forget the days when I worked together with you.
判断改错（注：先显示题,再显示答案,横线；用不同的颜色表示出.）
（错） This is the mountain village where I visited last year.
（错） I will never forget the days when I spent in the countryside.
（对） This is the mountain village (which) I visited last year.
（对） I'll never forget the days (which) I spent in the countryside.
习惯上总把表地点或时间的名词与关系副词 where, when联系在一起.此两题错在关系词的误用上.
方法二： 准确判断先行词在定语从句中的成分(主、谓、宾、定、状),也能正确选择出关系代词/关系副词.
例1. Is this museum ___ you visited a few days age?
A. where B. that C. on which D. the one
例2. Is this the museum ____ the exhibition was held.
A. where B. that C. on which D. the one
答案：例1 D,例2 A
例1变为肯定句： This museum is ___ you visited a few days ago.
例2变为肯定句： This is the museum ___ the exhibition was held.
在句1中,所缺部分为宾语,而where, that, on which都不能起到宾语的作用,只有the one既做了主句的表语,又可做从句的宾语,可以省略关系代词,所以应选D.
而句2中, 主、谓、宾俱全,从句部分为句子的状语表地点,既可用副词where,又因 in the museum词组,可用介词in + which 引导地点状语.而此题中,介词on 用的不对,所以选A.
关系词的选择依据在从句中所做的成分,先行词在从句中做主、定、宾语时,选择关系代词 (who, whom, that, which, whose)； 先行词在从句中做状语时,应选择关系副词 ( where 地点状语,when 时间状语,why 原因状语) .
18.4 限制性和非限制性定语从句
1) 定语从句有限制性和非限制性两种.限制性定语从句是先行词不可缺少的部分,去掉它主句意思往往不明确；非限制性定语从句是先行词的附加说明,去掉了也不会影响主句的意思,它与主句之间通常用逗号分开,例如：
This is the house which we bought last month. 这是我们上个月买的那幢房子.（限制性）
The house, which we bought last month, is very nice.这幢房子很漂亮,是我们上个月买的.（非限制性）
2) 当先行词是专有名词或物主代词和指示代词所修饰时,其后的定语从句通常是非限制性的,例如：
Charles Smith, who was my former teacher, retired last year. 查理·史密斯去年退休了,他曾经是我的老师.
My house, which I bought last year, has got a lovely garden. 我去年买的的那幢房子带着个漂亮的花园.
This novel, which I have read three times, is very touching. 这本小说很动人,我已经读了三遍.
3) 非限制性定语从句还能将整个主句作为先行词, 对其进行修饰, 这时从句谓语动词要用第三人称单数,例如：
He seems not to have grasped what I meant, which greatly upsets me. 他似乎没抓住我的意思,这使我心烦.
Liquid water changes to vapor, which is called evaporation. 液态水变为蒸汽,这就叫做蒸发.
说明：关系代词that和关系副词why不能引导非限制性定语从句.
18.5 介词+关系词
1）介词后面的关系词不能省略.
2）that前不能有介词.
3） 某些在从句中充当时间,地点或原因状语的"介词+关系词"结构可以同关系副词when 和where 互换.
This is the house in which I lived two years ago.
This is the house where I lived two years ago.
Do you remember the day on which you joined our club?
Do you remember the day when you joined our club?
