when和while引导的时间状语从句与这一时态连用
when和while引导的时间状语从句与这一时态连用

when和while引导的时间状语从句与这一时态连用。所以区别when和while的用法成了这一单元的难点。

(一)、when,while都有“当……时候”的意思。

when既可表示某一点时间,也可以表示某一段时间。在when引导的时间状语从句中,其谓语动词可以是延续性的,也可以是非延续性的,可与主句中的谓语动词同时发生,也可在其后发生。例如:

1、I was just reading a book when she came into my room.

她走进我房间时,我正在看书。

2、Were you writing when the teacher came in?

老师进来的时候,你在写信吗?

3、When he was a child he was always trying out new ideas.

他小时候就常常试验一些新的设想。

(二)、while只能表示某一段时间,不能表示某一点时间。在while引导的时间状语从句中,其谓语动词只能是延续性的,而且也只能与主句中的谓语动词同时发生或存在。

例如:

1、While Jim was mending his bike, Lin Tao came to see him.

正当吉姆修自行车时,林涛来看他。

2、You can’t do your homework while you’re watching TV.

你不能一边看电视一边做家庭作业。

(三)、另外,when和while的区别还在于:while引导的时间状语从句多用进行时态,而when 引导的时间状语从句多用一般时态。

例如:

1、While they were talking , the bell rang.

正在他们谈话的时候,上课铃响了。

2、I was doing my homework when my mother came back home yesterday evening.

昨天晚上妈妈回家的时候,我正在做家庭作

1. ----------she comes , I shall tell her to wait for you.

A. When

B. As

C. While

D. What

2. ----------she got older, she got wiser.

A. When

B. As

C. While

D. That

3.----------Peter was reading , his wife was cooking.

A. When

B. As

C. While

D. That

when as while

①when 表示较短的时间,有的时候也可以指一段时间。如:

When he was young, he could do eat much more than his brother.

②while常表示一段较长的时间,强调主句谓语动词与从句谓语动词同时发生。如:

你的第三道题就是这样。

③只用as, 不用when或while的时候。

A) 用于表示同一个人的两种动作交替进行,指"一边……,一边……"。如:

The girl dances as she sings on the stage.

B)表示两个同步发展的动作或行为,译为"随着……"。如:

As time went on, she became more and more worried.

when和while的区别

都表示“当......时候”的区别。请观察以下句子:

While in Vienna he studied music.

他在维也纳时学习音乐。

While he was eating, I asked him to lend me $2.

当他正在吃饭时,我请他借给我二英镑。

While two detectives were keeping guard at the door, two others opened the parcel. 这时两个侦探把着门,另外两个打开包裹。

While I read, she sang.

我看书时,她在唱歌。

I met her while I was at school.

当我在学校的时候我遇见了她。

Edison was not a good student when he was a young boy.

爱迪生小时候不是一个成绩好的学生。

When the plane arrived, some of the detectives were waiting inside the main building while others were waiting on the airfield.

当飞机抵达时,一部分侦探等在主楼里面,而另一部分则等在停机坪上。

When I came home my wife was cooking dinner.

我回家时,妻子在做晚饭。

通过观察,我们可以这样理解:when引导的从句里动作发生的时间相对主句动作发生的时间要短些;while引导的从句里的动作发生的时间相对主句而言更长些。

333 as,when,while意为although(尽管),

but(但是),seeing that(鉴于)

A 只有在形容词+as+主语+to be/to seem/to appear这一结构中,as才意为though/although(尽管):

Tired as he was he offered to carry her.相当于:

Though he was tired he offered to carry her.

尽管他很累了,他还主动提出要背着她。

Strong as he was,he couldn’t lift it.

尽管他力气很大,他仍提不起这个东西。

B while可意为but,用于表示强调对比:

‘At sea’means‘on a ship’,while‘at the sea’means‘at the seaside’.

“At sea”意为“在船上”,而“at the sea”意为“在海滩上”。

Some people waste food while others haven’t enough.

一些人糟踏食物而另一些人却食不果腹。

while可以意为although,这时常放在句首:

While I sympathize with your point of view I cannot accept it.

尽管我认同你的观点,但我不能接受它。

C when可以意为seeing that/although(鉴于)。因此它同while 很相似,但主要用于引导使另一个动作显得不合理的陈述句。

它常用在一个问句里,但不是一定如此:

How can you expect your children to be truthful when you yourself tell lies?

你自己都在撒谎,怎么能指望你的孩子们诚实?

It’s not fair to expect her to do all the cooking when she has had no training or experience.

她没有受过烹调方面的训练,也没有这方面的经验,让她把做饭的事全部承担下来是不公平的。

D 请务必不要搞混when与if的用法。

When he comes(等他来了)意为我们肯定他会来的。If he comes(如果他来了)意为我们不能肯定他是否会来

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.

引导时间状语从句的五类引导词

引导时间状语从句的五类引导词 引导时间状语从句的从属连词(以下称引导词)很多,为方便记忆,现作以下分类:1. 基本类 包括before, after, when, while, as, since, till, until, once, as soon as 等。如: Did anyone call when I was out? 我不在家时谁来过电话吗?

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

英语中连词while的用法归纳

英语中连词while的用法归纳 连词while除具有“当时”、“同时”等意义外,根据上下文还有以下不同含义及其不同译法。 一、引导时间状语从句 译作“当……时”。例如: 1. Make hay while the sun shines. 趁着有太阳晒晒草。 (乘机行事,抓紧时机。) 2. We must work hard to gain more knowledge while we are young. 趁着现在还年轻,我们必须刻苦学习,获得更多的知识。 二、引导让步状语从句 常放在句首,译作“尽管”、“虽然”,比although或though语气要轻。例如: 1. While I believe it is true, I cannot prove it. 虽然我相信那是真的,但我无法证明。 2. While any kind of athletic shoe can provide a certain amount of r ebound, energy-return sneakers are designed to maximize this effect. 虽然任何一种运动鞋都能提供一定的反弹力,但回力运动鞋能够使这种效果最大化。 三、引导条件状语从句 相当于as long as,译作“只要”。例如: 1. While there is life, there is hope. 有生命,就有希望。 2. While a spark of life remains, it is a doctor's duty to save the pat ient.

只要病人还有一息生机,医生就有责任挽救。 四、引导原因状语从句 相当于since,有“既然”的意思。例如: 1. You'll never save any money while you're so extravagant. 你这么奢侈,永远存不下钱来。 2. I'd like to get it settled today while we're at it. 既然我们着手干了,我想今天就把它干完。 五、连接并列句 表示对比,相当于whereas,译作“而”、“可是”。例如: 1. An outdoors man will soon become pale if he changes to an indo or job, while a desk clerk will take on a tan after a short vacation in the sun. 从事室外工作的人如果调到室内工作,不久肤色就会变白;而一个伏案工作的文员出去度个短假,就会被太阳变黑。 2. Motion is absolute while stagnation is relative. 运动是绝对的,而静止是相对的。 六、连接并列句 表示递进,相当于and what is more, 译作“并且”、“而且”。例如: 1. The new man-made fibres are more hardwearing than natural fibres and greatly reduce mending, while good ready-made clothes are cheap and pl entiful. 新的人造纤维比天然纤维耐磨,因此能大大减少修补工作,而且做好的衣服价廉物美,数量也多。 2. Of course, I resolutely determined not to marry, while I quite forg ot to consider at all that great rock of disaster in the working-class world-- sic kness. 当然, 我下定决心不结婚,而且把工人阶级的巨大灾难——疾病,也忘得一干二净。

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. While引导的从句的谓语动作必须是延续性的,并强调主句和从句的动作同时发生(或者相对应)。并且while有时还可以表示对比。例如: While my wife was reading the newspaper, I was watching TV. (was reading是延续性的动词,was reading和was watching同时发生) I like playing football while you like playing basketball.我喜欢踢足球,而你喜欢打篮球。(对比) 3. As表示“一边……一边”,as引导的动作是延续性的动作,一般用于主句和从句动作同时发生;as也可以强调“一先一后。例如: We always sing as we walk.我们总是边走边唱。(as表示“一边……一边”) As we was going out, it began to snow.当我们出门时,开始下雪了。(as强调句中两个动作紧接着先后发生,而不强调开始下雪的特定时间) as when while的辨析 as when while都表示主、从句动作同时发生,三者差异如下:

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)。

when,while和as引导时间状语从句的用法

when, while 和 as 引导时间状语从句的用法 这三个词的意思很简单,都有“当……时候”的意思。但学生经常会问三个词的区别在哪儿,特别是在做选择题的时候。别说是学生,就我个人而言,做这样的选择题要保证百分之百的 正确也是不可能的。现根据大量的实例和个人的思考,做一点小结,供大家参考。 一、when 的用法 如果只从现象来看,when 从句用的最多的是一般过去时,而主句的时态没有限制,根据具 体情况而定。 When he was a child he was always trying out new ideas. 他小时候就常常试验一些新的设想。 when she came into my room I was just reading a book. 她走进我房间时,我正在看书。 Were you writing when the teacher came in? 老师进来的时候,你在写信吗? Sorry,I was out when you called me. 对不起,你打电话来的时候我出去了。 He was on the point of leaving when someone knocked at the door. 他正要走,这时有人敲门。 I thought of it just when you opened your mouth. 就在你要说话的时候,我也想到了。 I had hardly[scarcely] closed my eyes when someone knocked at the door. 我刚一闭上眼,就有人在敲门了。 根据以上的例句,我们可以总结出一点:when 从句的A事件,相当于另一个事件B发生的时间点。也就是说,when 从句的重点不在动作本身发生的状态,而只是把它作为一个时间 点,所以when 多数情况下用的是一般过去时,则不用正在进行时。因为如果用正在进行时,它表示的就是一段时间而不是一个时间点了。根据这一点,有的文章补充说:when 从句的动词大多是瞬时动词。这种说法也可以参照。 实际上,when 从句也可以有其它的时态,但几乎也不用进行时,因为它也只是作为一个时 间参照点。例如: When I got to the airport,the guests had left. 当我赶到飞机场时,客人们已经离开了。 When he had finished his homework,he took a short rest. 当他完成作业后,他休息了一会儿。 Why do you want a new job when you have got such a good one already? 你已经找到如此好的工作,为何还想再找新的? You shall borrow the book when I have finished reading it.
