When引导的定语从句与时间状语从句的区分
When引导的定语从句与时间状语从句的区分

一、从句是如何出题的

1. 时态

2. 考连接词

3. 考语言顺序

二、学好从句的两个基本条件

1. 时态

2. 从句的三个必须:①必须是句子;②必须有连接词;③必须是陈述句

三、状语从句、宾语从句、定语从句重点

1.如何判断何种从句

2. 从句的时态

3. 从句的连接词与扩展

4. 经典单选、从句与选词、长句子分析

四、如何判断三种从句

1. 状语从句无先行词

2. 宾语(表语)从句无先行词有动词或词组

3. 定语从句先行词多为名词或代词

一、When引导的定语从句与时间状语从句的区分

1. when的译法不同。在时间状语中,when 翻译成“当……的时候”I want to be a teacher when I grow up. 当我长大的时候,我要做一名老师。在定语从句中,when不翻译。I won't forget the day when he says he loves me. 我不会忘记他说爱我的那一天。

2. 在时间状语中,when从句前面或后面是句子;定语从句中,when从句不能位于句首,且通常when前为表示时间的名词day、year等。

3. when在从句的作用不同。在时间状语从句中,when是连词,只起连接主句和从句的作用,不做从句的任何成分。不过when引导的时间状语从句修饰主句的谓语,做主句的时间状语。

在定语从句中,when是关系副词,在从句中代替先行词做从句的时间状语,修饰从句的谓语。

例1 I will always remember the days when I lived with my grandparents in the country.

例2 I always remember the days in the country when I see the photo of my grandparents.

点评:例1意为“我会永远记得跟我祖父母一起住在乡下的那些日子”,其中when 引导的是一个定语从句, 修饰the days, when在从句中作时间状语。例2意为“当我看到祖父母的照片时,总是会想起在

乡下的那些日子”,其中when 引导的从句并不修饰前面的名词the country,因此可判定为时间状语从句。

例1中的when可用in which替代,即从句可改为...in which I lived with my grandparents in the country. 例2中从句前有名词,但根据句意可

知并不是从句所修饰的对象,也不能用“介词+ which”来替代。

二、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. 这是我

去年呆过的山村。

I'll never forget the days when I worked together with you.

我永远不会忘记与你共事的日子。

判断改错:

1. This is the mountain village where I visited last year.

2. I will never forget the days when I spent in the countryside.

3. This is the mountain village (which) I visited last year.

4. I'll never forget the days (which) I spent in the countryside.

(错)(错)(对)(对)

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 ago

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)。

答案解析:

1. 解析:关系副词when引导定语从句,在句中作时间状语。

答案:A。

2. 解析:考查状语从句与定语从句的辨析。主句已经包含有主、谓、宾和地点状语,when连接时间状语从句,其他选项不合题意。答案:B。

3. 解析:tell后接宾语从句。宾语从句部分谈及未来的事情,所以应该用一般将来时、陈述句词序。答案:A。

4. 解析:这是定语从句,先行词是age,表示时间,所以要用when。答案:D。

5. 解析:1980前面没有介词,所以第一个空应选It,指时间;第二个空应选when,引导时间状语从句。注意该题不是强调句型,如果看作强调句型,去掉It was和that后,句子应成立。如果1980前面有in,则是强调句型,强调时间状语in 1980。答案:A。

6. 解析:when是关系副词,表示时间,在定语从句中作时间状语。答案:C。

7. 解析:本题考查地点状语从句。题意是“那位著名科学家是在出生地长大的,1930年来到上海的”。关系副词wherever相当于no matter where,通常引导让步状语从句。答案:C。

8. 解析:which是关系代词,在从句中作forget的宾语。其他几个答案都不能作宾语。答案:B。

9. 解析:when引导时间状语从句;强调丁俊辉赢得比赛时的心情。答案:B。

10. 解析:两个先行词the day都是表示时间的名词,但第一个空白处要填的关系词在从句中作状语,因此要用关系副词when. 第二个空白处要填的关系词在从句中作动词spent的宾语,因此要用关系代词which 或that来引导定语从句。答案:D。

when 和 where 引导定语从句的用法

when 和 where 引导定语从句的用法 定语从句既是英语语法的一个重点,同时又是一个难点。说它是难点,主要难在两点上:一点是如何正确判断什么样的汉语句子要译为英语的带定语从句的复合句;另一点是定语从句的引导词较多(包括关系代词who, that, which, as 和关系副词when, where, why),而且其用法也较复杂。那么到底什么情况下用when和where来引导定语从句呢?它们又该怎么用呢?下面就举例说明: 一、when:当主句中的先行词(即主句中被后面定语从句修饰的词)是表示时间意义的名词时,它只能作定语从句的时间状语,放在定语从句句首。如果定语从句的引导词是作该定语从句的主语或宾语,则要改用关系代词that或which来引导。例如: The days when we used foreign oil are gone. 我们用洋油的日子一去不复返了。 I'll never forget the day when I was born. (=I'll never forget my birthday.) 我永远不会忘记我出生的日子。 It happened in November when the weather was wet and cold. 这事发生在天气又湿又冷的十一月。 In the years that (which) followed, Marx kept on studying English and using it. 在这之后的几年中,马克思继续学习和使用英语。(that作定语从句"that followed"的主语) The day (that) I always remember in all my life is my birthday. 我一生中最难忘的日子是我的生日。(that作定语从句"that I always remember in all my life"的宾语,that可以省略)

grandparents in the country. 例2 I always remember the days in the country when I see the photo of my grandparents. 点评:例1意为“我会永远记得跟我祖父母一起住在乡下的那些日子”,其中when 引导的是一个定语从句, 修饰the days, when在从句中作时间状语。例2意为“当我看到祖父母的照片时,总是会想起在乡下的那些日子”,其中when 引导的从句并不修饰前面的名词the country,因此可判定为时间状语从句。 例1中的when可用in which替代,即从句可改为...in which I lived with my grandparents in the country. 例2中从句前有名词,但根据句意可 知并不是从句所修饰的对象,也不能用“介词+ which”来替代。 二、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. 这是我去年呆过的山村。 I'll never forget the days when I worked together with you. 我永远不会忘记与你共事的日子。 判断改错: 1. This is the mountain village where I visited last year. 2. I will never forget the days when I spent in the countryside. 3. This is the mountain village (which)I visited last year.

过去进行时、when和while引导时 间状语从句的区别

过去进行时过去进行时表示过去某一时刻或者某段时间正在进行或发生的动作,常和表过去的时间状语连用,如: 1. I was doing my homework at this time yesterday. 昨天的这个时候我正在做作业。 2. They were waiting for you yesterday. 他们昨天一直在等你。 3. He was cooking in the kitchen at 12 o'clock yesterday. 昨天12点,他正在厨房烧饭。 过去进行时的构成: 肯定形式:主语+was/were+V-ing 否定形式:主语+was not (wasn't)/were not (weren't)+V-ing 疑问形式:Was/Were+主语+V-ing。 基本用法: 1. 过去进行时表示过去某一段时间或某一时刻正在进行的动作。常与之连用的时间状语有,at that time/moment, (at) this time yesterday (last night/Sunday/week…), at+点钟+yesterday (last night / Sunday…),when sb. did sth.等时间状语从句,如: 1)What were you doing at 7p.m. yesterday? 昨天晚上七点你在干什么? 2)I first met Mary three years ago. She was working at a radio shop at the time. 我第一次遇到玛丽是在三年前,当时她在一家无线电商店工作。 3)I was cooking when she knocked at the door. 她敲门时我正在做饭。 2. when后通常用表示暂短性动词,while后通常用表示持续性动词,而while所引导的状语从句中,谓语动词常用进行时态,如: When the car exploded I was walking past it. = While I was walking past the car it exploded. 3. when用作并列连词时,主句常用进行时态,从句则用一般过去时,表示主句动作发生的过程中,另一个意想不到的动作发生了。如: I was walking in the street when someone called me. 我正在街上走时突然有人喊我。 4. when作并列连词,表示“(这时)突然”之意时,第一个并列分句用过去进行时,when引导的并列分句用一般过去时。如:

When引导的定语从句与时间状语从句的区分

一、从句是如何出题的 1. 时态 2. 考连接词 3. 考语言顺序 二、学好从句的两个基本条件 1. 时态 2. 从句的三个必须:①必须是句子;②必须有连接词;③必须是陈述句 三、状语从句、宾语从句、定语从句重点 1.如何判断何种从句 2. 从句的时态 3. 从句的连接词与扩展 4. 经典单选、从句与选词、长句子分析 四、如何判断三种从句 1. 状语从句无先行词 2. 宾语(表语)从句无先行词有动词或词组 3. 定语从句先行词多为名词或代词 一、When引导的定语从句与时间状语从句的区分 1. when的译法不同。在时间状语中,when 翻译成“当……的时候”I want to be a teacher when I grow up. 当我长大的时候,我要做一名老师。在定语从句中,when不翻译。I won't forget the day when he says he loves me. 我不会忘记他说爱我的那一天。 2. 在时间状语中,when从句前面或后面是句子;定语从句中,when从句不能位于句首,且通常when前为表示时间的名词day、year等。 3. when在从句的作用不同。在时间状语从句中,when是连词,只起连接主句和从句的作用,不做从句的任何成分。不过when引导的时间状语从句修饰主句的谓语,做主句的时间状语。 在定语从句中,when是关系副词,在从句中代替先行词做从句的时间状语,修饰从句的谓语。 例1 I will always remember the days when I lived with my grandparents in the country. 例2 I always remember the days in the country when I see the photo of my grandparents. 点评:例1意为“我会永远记得跟我祖父母一起住在乡下的那些日子”,其中when 引导的是一个定语从句, 修饰the days, when在从句中作时间状语。例2意为“当我看到祖父母的照片时,总是会想起在

when,where,why引导的定语从句

when,where,why引导的定语从句 when,where,why作为定语从句的引导词,总称为关系副词。下面用句子合并的方法分析它们的使用。 一、where引导的定语从句 请分析下面两个简单句: 句①I know a garden. 句②You can find wild strawberries there. 把句②变为句①的定语从句,句①中的agarden做定语从句的先行词。在句②中there指句①中提到的agarden也就是定语从句的先行词,there在句中做地点状语,因此要用where 引导定语从句,代替句②中的there,也就是说there就不能出现在定语从句中了。由此得到句③I know a garden where you can find wild strawberries. 句②还可以写作句④You can find wild strawberries in it(it指句①中的garden,“在花园中”要使用介词短语in the garden)。把句④变为句①的定语从句,因为it做介词in 的宾语,先行词是agarden,指物。在这种定语从句中介词常常提到定语从句的开始,这时关系代词只能使用which替代it,it就不能在定语从句中出现了。由此得到句⑤即:I know a garden in which you can find wild strawberries. 请把下面每组的两句话合并为一句,把第二句话变为第一句的定语从句。 第一组: This is the village. I was born there. →This is the village where I was born. 第二组: The lab is not far from here. The chemist often does experiments there. →The lab where the chemist often does experiments is not far from here.

when,while,as引导时间状语从句的区别

when,while,as引导时间状语从句的区别 when,while,as显然都可以引导时间状语从句,但用法区别非常大。 一、when可以和延续性动词连用,也可以和短暂性动词连用;而while和as只能和延续性动词连用。 ①Why do you want a new job when youve got such a good one already?(get 为短暂性动词)你已经找到如此好的工作,为何还想再找新的? ②Sorry,I was out when you called me.(call为短暂性动词)对不起,你打电话时我刚好外出了。 ③Strike while the iron is hot.(is为延续性动词,表示一种持续的状态)趁热打铁。 ④The students took notes as they listened.(listen为延续性动词)学生们边听课边做笔记。 二、when从句的谓语动词可以在主句谓语动作之前、之后或同时发生;while 和as从句的谓语动作必须是和主句谓语动作同时发生。 1.从句动作在主句动作前发生,只用when。 ①When he had finished his homework,he took a short rest.(finished先发生)当他完成作业后,他休息了一会儿。 ②When I got to the airport,the guests had left.(got to后发生)当我赶到飞机场时,客人们已经离开了。 2.从句动作和主句动作同时发生,且从句动作为延续性动词时,when,while,as都可使用。 ①When /While /As we were dancing,a stranger came in.(dance为延续性动词)当我们跳舞时,一位陌生人走了进来。 ②When /While /As she was making a phonecall,I was writing a letter.(make为延续性动词)当她在打电话时,我正在写信。 3.当主句、从句动作同时进行,从句动作的时间概念淡化,而主要表示主句动作发生的背景或条件时,只能用as。这时,as常表示“随着……”;“一边……,一边……”之意。 ①As the time went on,the weather got worse.(as表示“随着……”之意) ②The atmosphere gets thinner and thinner as the height increases.随着高度的增加,大气越来越稀薄。 ③As years go by,China is getting stronger and richer.随着时间一年一年过去,中国变得越来越富强了。 ④The little girls sang as they went.小姑娘们一边走,一边唱。 ⑤The sad mother sat on the roadside,shouting as she was crying.伤心的妈妈坐在路边,边哭边叫。 4.在将来时从句中,常用when,且从句须用一般时代替将来时。 ①You shall borrow the book when I have finished reading it.在我读完这本书后,你可以借阅。 ②When the manager comes here for a visit next week,Ill talk with him about this.下周,经理来这参观时,我会和他谈谈此事。 三、when用于表示“一……就……”的句型中(指过去的事情)。 sb.had hardly(=scarcely)done sth.when...=Hardly /Scarcely had sb.done sth.when...

When引导的三类从句

When引导的三类从句 When作为连词,可以引导名词从句、定语从句和时间状语从句。请看下面这段短文,其中就出现了when引导的这三类从句。 1. (a) Many students say that their time at university is when they can experience pure love. (b) This is a time when love is innocent when two people come together for love, rather than a house, car or a good job. There are no pressures from parents to get married as they are still young. (c)It is a time when they can choose who they love and how they love away from outside pressure. Even though the relationship may break up, it will bring sweet memories in later years. 很多学生都说,在大学期间才能经历真正纯真的爱情。在此期间,爱是单纯的,两个人走到一起完全是因为爱,而不是为了房子、车子或者好工作。由于还年轻,他们也不会迫于父母的压力而结婚。这一期间,他们可以不受外界的任何干扰而去选择自己爱的对象和爱的方式。即使最终两人分手了,这期间的爱情也会成为日后甜蜜的回忆。 上面的小短文中出现了四个when引导的从句,下面笔者逐一分析各句的结构与类型。首先来看a句: a. Many students say that their time at university is when they can experience pure love. 我们可以看到,这里when引导的从句用在了系动词is后,也就是说,这一从句是一个表语从句(名词从句的一种)。这里的when相当于

when引导的定语从句的用法

when/where/why引导的定语从句的用法 when, where, why属于关系副词,都在其引导的定语从句中充当状语,其具体用法如下: 1. 关系副词 when引导定语从句(包括限定性定语从句和非限定性定语从句)修饰表示时间的先行词,在定语从句中充当时间状语。例如: I still remember the day when I first met Jennifer.我仍然记得第一次见到詹妮弗的那一天。// Next month, when you’ll spend your summer holidays in your hometown, is approaching. 下个月即将来临,届时你们将在家乡度暑假。 2. 关系副词where引导定语从句(包括限定性定语从句和非限定性定语从句)修饰表示地点的先行词,在定语从句中充当地点状语。例如: This is the office where he worked. 这就是他工作过的办公室。// She is going to live in Macao, where she has some close friends. 她要到澳门去定居,在那里她有几个密友。 3. 关系副词why引导限定性定语从句修饰先行词reason,在定语从句中充当原因状语。例如: I don’t know the reason why he came so late. 我不知道他来得那么晚的原因。// That is the reason why I don’t want to go. 那就是我不想去的理由。// He didn’t tell me the reason why he was so upset.他没有告诉我他为什么那样心烦意乱。 注意:关系代词与关系副词之间并非毫无关联,两者之间存在密切的联系。在备考中尤其要注意以下几点: 1. 很多情况下关系副词用“介词+which/whom”来代替,其中的介词由先行词或定语从句中谓语动词的形式来决定,例如: The day when I met the famous pop star was the greatest day of my life. = The day on which I met the famous pop star was the greatest day of my life. 见到这位著名歌星的那天是我一生中最重要的日子。 I shall never forget those years when I lived with her. = I shall never forget those years during which I lived with her. 我将永远不会忘记我跟她生活的那些岁月。 This is a hall where the medical conference will be held. = This is a hall in which the medical conference will be held. 这是礼堂,医学会议将在此召开。 2. 并非先行词表示时间或地点时都分别用when或where来引导相应的定语从句,若关系词在修饰表示时间或地点的先行词的定语从句中充当主语、宾语等而不是状语时,需用which或that 引导相应的定语从句。例如: Do you still remember the days which/that we spent together in school? 你还记得我们一起在学校度过的那些日子吗? 先行词the days表时间,但是其定语从句的引导词在定语从句中作宾语而不是状语,因此不能用when而应该用which或that。 3. that有时可以代替定语从句中的关系副词when, where, why,且that常可以省略,例如: This is the time (when/that) he arrived. 这是他到达的时间。 [考题1] We are living in an age ____ many things are done on computer. (2003北京春) A. which B. that C. whose D. when [答案] D [解析]本题中下划线处所引导的限定性定语从句修饰表示时间的先行词age,其引导词在该定语从句中充当时间状语,因此只能填入关系副词when。 [考题2] The film brought the hours back to me ____ I was taken good care of in that far*9鄄away village. (2001) A. until B. that C. when D. where [答案] C [解析]本题中下划线处所引导的限定性定语从句修饰表示时间的先行词hours,其引导词在该定语从句中充当时间状语,因此只能填入关系副词when。 [考题3] It was an exciting moment for these football fans this year, ____ for

引导的时间状语从句

1.由when, while, as引导的时间状语从句。 When you think you know nothing, then you begin to know something.当你以为自己一无所知的时候,你就是在开始知道一些事物了。When truth is buried under the ground it grows, it chokes, it gathers such an explosive force that on the day it bu rsts out , it blows up everything with it.当真理被埋在地下的时候,它在生长,它感到压抑,它蓄存着这么一种爆炸性力量,一旦冒出,它就会炸破一切! Strike while the iron is hot. 趁热打铁。 Will you watch my clothes while I have a swim? 我游泳的时候,请你照看一下我的衣服。 You can feel the air moving as your hand pushes through it . 当你的手在空气中挥动的时候,你就能感觉到空气在流动。 Our headmaster laughed as she spoke.我们的校长边谈边笑。 when, while和as的区别 1. when引导的从句的谓语动词可以是延续性的动词,又可以是瞬时动词。并且when有时表示“就在那时”。 例如: When she came in, I stopped eating.她进来时,我在吃饭。(瞬时动词) When I lived in the countryside, I used to carry some wate r for him.当的住在农村时,我常常为他担水。(延续性的动词) We were about to leave when he came in.我们就要离开,就在那时他进来了。 2.

When,While,As引导时间状语从句的区别

When,While,As引导时间状语从句的区别 when,while,as显然都可以引导时间状语从句,但用法区别非常大。 一、when可以和延续性动词连用,也可以和短暂性动词连用;而while和as 只能和延续性动词连用。 ① Why do you want a new job when you’ve got such a good one already?(get为短暂性动词)你已经找到如此好的工作,为何还想再找新的? ②Sorry,I was out when you called me.(call为短暂性动词)对不起,你打电话时我刚好外出了。 ③Strike while the iron is hot.(is为延续性动词,表示一种持续的状态)趁热打铁。 ④ The students took notes as they listened.(listen为延续性动词)学生们边听课边做笔记。 二、when从句的谓语动词可以在主句谓语动作之前、之后或同时发生;while 和as从句的谓语动作必须是和主句谓语动作同时发生。 1.从句动作在主句动作前发生,只用 when。 ①When he had finished his homework,he took a short rest.(finished 先发生)当他完成作业后,他休息了一会儿。 ②When I got to the airport,the guests had left.(got to后发生)当我赶到飞机场时,客人们已经离开了。 2.从句动作和主句动作同时发生,且从句动作为延续性动词时,when,while,as都可使用。 ①When /While /As we were dancing,a stranger came in.(dance为延续性动词)当我们跳舞时,一位陌生人走了进来。 ②When /While /As she was making a phone call,I was writing a letter.(make为延续性动词)当她在打电话时,我正在写信。 3.当主句、从句动作同时进行,从句动作的时间概念淡化,而主要表示主句动作发生的背景或条件时,只能用 as。这时,as常表示“随着……”;“一边……,一边……”之意。 ① As the time went on,the weather got worse.(as表示“随着……”之意) ② The atmosphere gets thinner and thinner as the height increases.随着高度的增加,大气越来越稀薄。 ③As years go by,China is getting stronger and richer.随着时间一年一年过去,中国变得越来越富强了。 ④The little girls sang as they went.小姑娘们一边走,一边唱。 ⑤The sad mother sat on the roadside,shouting as she was crying.伤心的妈妈坐在路边,边哭边叫。 4.在将来时从句中,常用when,且从句须用一般时代替将来时。 ①You shall borrow the book when I have finished reading it.在我读完这本书后,你可以借阅。 ②When the manager comes here for a visit next week,Ill talk with him about this.下周,经理来这参观时,我会和他谈谈此事。 三、when用于表示“一……就……”的句型中(指过去的事情)。
