    从一道高考题综述while的用法

    先看下面一道高考题:

    -I\”m going to the post office.

    -________you\”re there,can you get me some stamps?

    A.As B.While C.Because D.If

    对连词的用法考查在每年高考题中均有涉及.Because引导原因状语从句,If引导条件状语从句,按题干提供的情景均不可取.While和As都能引导时间状语从句,极易混淆.As一般强调主句谓语动词与从句谓语动词动作的同时性,而While除可表示同时性外,还含有一个动作在另一个动作正在进行或持续过程中的某一时刻发生.再从题干所提供的情景判断,就可知道B为最佳答案.

    while的用法可从下述几点理解与运用.

    一、while意为\"当.时候\",指一段时间,不能用来表示一个时间点.

    While the discussion was still going on,George came in.当讨论还在进行时,乔治走了进来.

    二、while意为\"而;然而\",表示转折.

    There\”re plenty of rain in the southeast,while there\”s little in the northeast.东南部雨量充足,而西北部则很少下雨.

    三、while意为\"虽然;尽管\",表示让步.

    While I admit his good points,I can see his shortcomings.尽管我承认他的优点,但我还是能看到他的缺点.

    四、while意为\"只要\",表示条件.

    We can surely overcome these difficulties while we are closely united.只要我们紧密地团结一致,一定能克服这些困难.

    五、while从句中的省略.

    当while从句中的主语与主句的主语一致,且含有be的某种形式时,从句中的主语连同be可同时省略.

    While listening to the radio,she fell asleep.她在听收音机时睡着了.

    While in London,he studied music and painting.在伦敦时,他学习音乐和绘画.

    六、while可用作名词,意为\"一会儿;一段时间\".

    作名词用时,主要用于短语中:after a while \"过了一会儿\"; all the while \"一直,始终\"; a short / little while ago \"刚才\"; once in a while \"偶尔,间或\"; wait / rest(for) a while \"等 / 休息一会儿\".

    I haven\”t seen her for a long while.我好久没有看见她了.

    Where have you been all this while?这一阵子你到哪去了?

    He usually goes to work by bike,but once in a while he goes by bus.他通常骑自行车上班,但偶尔也乘公共汽车.

    I looked everywhere for the letter,but it was in my pocket all the while.我到处找那封信,却不知它一直在我口袋里.

    七、while与when以及as之间的区别.

    1.当从句中的谓语动词是持续性的动作时,我们可以用while,when或as.

    While / When / As I was walking down the street,I noticed a police car in front of the bank.我顺着马路往前走时,发现银行门前停着一辆警车.

    2.当从句中的谓语动词表示瞬间动作时,不可用while.

    He was on the point of leaving when someone knocked at the door.他正要走,这时有人敲门.

    3.如果谈论两个长动作,最常用的是while.

    While John was sitting biting his nails,I was working out a plan to get us home.约翰坐在那里咬指甲时,我想出了一个回家的办法.

    不过,as是可以用来说明两种正在发展或变化的情况的,这时as引导一个持续性的动作,主句中的动作与之同时进行.

    As we talked on,he got more and more excited.我们继续往下谈的时候,他越来越兴奋.

    4.如果表示两个短动作或事件同时发生,最常用的是as或just as,也可用when.

    Just as he caught the ball,there was a tearing sound.当他抓住球的时候,有一种撕裂的声音.

    I thought of it just when you opened your mouth.就在你要说话的时候,我也想到了.

    提示:

    while的用法 while 一段时间;当……时(和……同时);却

    (1)I”ll be back for a while

    (2)He fell asleep while doing homework.

    (3)John was dressed in brown while Mary was ...

    类似问题1:While的用法[英语科目]

    一、 while 用作名词时,意为“一段时间,一会儿”.例如:

    I stayed there for a short while.

    (我在那儿呆了一小会儿.)

    The postman came a short while ago.

    (邮递员刚刚来过.)

    二、 while 用作连词时,有以下几种含义:

    1. 意为“当……时候,和……同时”,引导时间状语从句.例如:

    While I was watching TV, the bell rang.

    (我看电视时,铃响了.)

    Meimei watched TV while she ate her supper.

    (梅梅边吃晚饭边看电视.)

    2. 意为“虽然,尽管”,引导让步状语从句.例如:

    While it was late, he went on working.

    (虽然很晚了,但他还在继续工作.)

    While he is in poor health, he works hard.

    (虽然他身体不好,但他还是努力工作.)

    3. 连接两个并列句子,表示“对比”关系.例如:

    He went out for a walk, while I stayed at home.

    (他出去散步了,而我却呆在家里.)

    I like singing while she likes dancing.

    (我喜欢唱歌,而她喜欢跳舞.)

    You like sports, while I prefer music.

    (你喜欢体育,而我更喜欢音乐.)

    三、 while 引导状语从句时,应注意以下几点:

    1. while 引导的时间状语从句既可放在句首,也可放在句末;而 while 引导的让步状语从句一般放在句首,不放在句末.另外,也可以从意义上加以区分.例如:

    While he was tired, he went on working.

    (虽然他累了,但他还是继续工作.)

    ( while 引导让步状语从句)

    While he was tired, he would have a rest.

    (他累了就休息一会儿.)

    ( while 引导时间状语从句)

    2. while 引导让步状语从句时,如果从句的主语和主句的主语相同,那么从句的主语和谓语动词 be 都可以省略.例如:

    While he was ill, he went there. (= While ill, he went there.)

    (虽然他有病,但他还是去那里了.)

    3. while 和 when 都可以引导时间状语从句,但应注意: while 引导的时间状语从句中的谓语动词必须是延续性的动词;而 when 引导的时间状语从句中的谓语动词既可以是延续性动词,也可以是非延续性动词.当时间状语从句中的谓语动词是延续性动词时, while 和 when 可以互相替换.例如:

    While we were talking, the teacher came in.

    (我们正在谈话时,老师进来了.)

    The bus had left when we arrived at the bus stop.

    (当我们到达车站时,公共汽车已经开走了.)

    ( arrive 是非延续性动词,因此,此句中的 when 不能用 while 替换.)

    When / While we were having a meeting, our teacher came in.

    (我们正在开会时,老师走了进来.)

    ( have 是延续性动词,因此,句中的 when 可以用 while 替换.)

    4. while 引导的状语从句还可以表示“某个动作正在进行的同时,另一个动作也在进行之中”.例如:

    While the teacher was speaking, the students were listening.

    (老师讲课时,学生们在听.)

    While he was writing, I was reading.

    类似问题2:请问while用法[英语科目]

    When和While的区别

    ①when是at or during the time that, 既指时间点,也可指一段时间,while是during the time that,只指一段时间,因此when引导的时间状语从句中的动词可以是终止性动词,也可以是延续性动词,而while从句中的动词必须是延续性动词.

    ②when 说明从句的动作和主句的动作可以是同时,也可以是先后发生;while 则强调主句的动作在从句动作的发生的过程中或主从句两个动作同时发生.

    ③由when引导的时间状语从句,主句用过去进行时,从句应用一般过去时;如果从句和主句的动作同时发生,两句都用过去进行时的时候,多用while引导,如:

    a. When the teacher came in, we were talking.

    当此句改变主从句的位置时,则为:

    While we were talking, the teacher came in.

    b. They were singing while we were dancing.

    ④when和while 还可作并列连词.when表示“在那时”;while表示“而,却”,表对照关系.如:

    a. The children were running to move the bag of rice when they heard the sound of a motor bike.

    孩子们正要跑过去搬开那袋米,这时他们听到了摩托车的声音.

    b. He is strong while his brother is weak.

    他长得很结实,而他弟弟却很瘦弱.

    谓语动词是与非谓语动词相对应的概念.两者都是动词,但是前者是作谓语成分,后者不能作谓语成分.而谓语成分就是用来说明主语的动作或状态的,一般由动词或短语动词承担.

    比如:我看电视.”看”就是谓语.

    你正在上网.”上网”也是谓语.

    再举几个英语句子吧:I see a girl.我看见一个女孩.”看见””see"就是这个句子的谓语.而see也是个动词,所以就叫做谓语动词.She is very beautiful.她很漂亮."is"就是这个句子的谓语,也是动词.

    从句是指用于复合句中担当某个句子成分的主谓结构.虽说从句自身的句子结构是完整的, 但是它不能视为独立的句子,因为它离开了主语就无法独立、完整地表达意思.按其所能表达的意义而言,它相当于一个词或是一个词组.例如: 1) Because they talk at home while the television is on , many people think they can talk at movies as well . (状语从句)许多人在家里是边看电视边谈话,所以他们认为在电影院也可以如此. 2) Whether he comes or not doesn't make any difference to me . (主语从句) 他来与不来对我都一样. 3)There is disagreement among economists about what money is and how money is measured(宾语从句)什么是货币以及怎样计量货币经济学家之间存有分歧. 4) China is not what it used to be . (表语从句)中国不是它过去的样子了. 5) Is there any proof that the food of plant differs from that of animals ? (同位语从句)有没有什么证据说明植物性食品不同于动物性食品? 6) Taxes consist of money that people pay to support their government . (定语从句) 税款是人们支持政府而交的钱. 如果将上面的复合句中所有的从句都独立出来,那将是这样的: 1) Because they talk at home while the television is on 2) Whether he comes or not 3) what money is and how money is measured 4) what it used to be 5) that the food of plant differs from that of animals 6) that people pay to support their government 我们很容易看出,上面的所有这些句子既不是陈述句、疑问句,也不是祁使句,更不是感叹句.也就是说,它们不是独立的句子;也只有在附属于主句后才能获得意义如下:1)因为许多人在家里是边看电视边谈话 2)他来与不来 3)什么是货币以及怎样计量货币 4)它过去的样子5)植物性食品不同于动物性食品6)人们支持政府而交的上面的这些句子在我们中文里如同是人们常说的"半截话";在英文中也就是个"词或词组"了. B. 我们虽然说过,从句自身的句子结构基本是完整的,但是它不同于"独立句子"的是--每个从句的最前面都好象"戴了顶帽子"即:从属关系词.由此可以看出,从句的另一个特点是:从属关系词总是立于从句之首. C. 从句的再一个特点是:一般说来(除少数倒装的情况外),从句中的语序应该是正常语序. D. 关于从句种类的划分有两种方法:按从句的词性划分和按从句的句子功能划分.如果按从句的词性划分,从句可分为三种:名词从句、形容词从句和副词从句.如果按从句的句子功能划分(也就是按从句在句子中所担任的成分来划分),从句可分为:主语从句、宾语从句、 表语从句、同位语从句、定语从句和状语从句.其实,这两种划分从句的方法在逻辑上是一致的.我们知道,能在句子里充当主语、宾语、表语和同位语的往往是名词、代词等,所以名词从句涵盖了主语从句、宾语从句、表语从句和同位语从句.形容词和副词常分别在句中担当定语和状语,所以,形容词从句和副词从句其实分别是定语从句和状语从句. 名词从句名词从句在句中是一个相当于名词的主谓结构.我们在前面说过,名词从句含盖了主语从句、宾语从句、表语从句和同位语从句.连接这些从句与主句的关系词主要有三类: 1.从属连词:that(无有词义) , whether(是否) ,if (是否) 2.关系代词:who(谁,主格) , whom(谁,宾格),whose谁的,所有格) , what(什么),which(哪个,哪些) 3.关系副词:when(什么时候) where(什么地方)why(为什么) , how(怎样) 名词从句中的从属连词在从句里不担任任何成分,只起连接的作用;而关系代词和关系副词不仅仅是起连接的作用,而且还在从句里担任一定的成分;关系代词常在从句中担任主语、宾语或表语等成分;关系副词常在从句中担任状语.另外,在使用上面的这些关系词时,有几个问题值得我们注意:首先,只能用whether而不能用if的情况. 1)引导主语从句,例如: Whether we'll make a loan for the project has not been decided .(正确)我们是否要为这个项目还没有定下来. OR: It has not been decided whether we'll make a loan for the project . (正确) If we'll make a loan for the project has not been decided .(错误) OR: It has not been decided if we'll make a loan for the project . (错误) 2)作介词的宾语,例如: I have no idea about whether I can raise the money for buying a car . (正确)我不知道我是否能为买车筹措到资金. I have no idea about if I can raise the money for buying a car . (错误) 3)后接不定式 ,例如: He didn't know whether to go all himself first or wait for her here.(正确)他不知道是他自己先去还是在这儿等她. He didn't know if to go all himself or wait for her here . (错误) 4)后接or not ,例如: We wonder whether they'll come in time or not.(正确) 我们担心他们会不会准时到. We wonder if they'll come in time or not . (错误)其次,what引导的名词从句表达的意思是"……所……的".这个"所怎么的"定义根据"从句谓语的动作意义"而定.例如: I don't understand what you said.我不理解你所说的话. What he needs is to practice more.他所需要的是勤于练习. Money is what she is really after.金钱是她所真正追求的东西. People have different ideas about what happiness means . 人们对于幸福的含义有不同见解.最后,要了解 -ever = no matter ,用于表示强调,意为"无论……".也就是说: whatever = no matter what(无论什么) whoever = no matter who(无论谁) whichever = no matter which(无论那个) whenever =no matter when (无论何时) wherever = no matter where(无论何地) however = no matter how (无论怎样) A 主语从句用作主语的主谓结构称之为主语从句.例如: Whether he'll come or not remains a question . 他是否会来依然是一个问题. Whoever says that is not allowed .无论谁这样说都是不允许的. That she reads English aloud every morning helps her a lot in the improvement of her English study . 她每天早晨朗读英文对提高她的英语学习起了很大的作用. 要点提示在使用主语从句中,有几个问题值得我们注意: 1)尽管主从连词that在主语从句中没有任何意义,但一般不能省略. That there is no elevator in the building is the critical inconvenience .这幢楼里没有电梯是极大的不便之处. It is necessary (that) he have his further study incollege.(当主语从句在后面时,连词that可以省去)他在大学进一步深造是完全必要的. 2)为了保持句子平衡或在正式文体中,常用先行It代替主语从句而将主语从句置于句末. It remains a question Whether he'll come or not . 他是否会来,依然是一个问题. It is not allowed Whoever says that. 无论谁这样说都是不允许的. 3)在It + be +形容词/ 名词 + that从句的结构中,由于某些形容词/ 名词的原因,that从句中的谓语动词要用虚拟式.这类形容词/ 名词常见的有: essential(绝对必要的), important(重要的), advisable(明智的), desirable(希望能够的), imperative(必须的), natural(自然的), necessary必要的), regretful(遗憾的), strange(奇怪的), proper(适当的), urgent(紧急的), duty(义务、责任), a pity (遗憾), no wonder(难怪), a regret(遗憾).例如: It is strange that he ( should ) say so . 他居然会这样说,真是奇怪. It is a great pity that you ( should ) think so . 他居然会这样想,真是一件憾事. It is natural that a bird ( should ) rest in trees . 鸟在树上安歇是很自然的. It is a wonder that he should have passed the exam. 他这次考试居然会及格,真是个奇迹. 4)以what引导的主语从句常用于句首表示强调. What they need now is financial aid . 他们现在所需要的是经济援助. What she thinks of me doesn't mean much to me . 她怎么样看我,对我来说无所谓. What you have said hurt her a lot .你所说的话对她伤害很大. B 宾语从句用作谓语动词、介词以及非谓语动词形式的宾语的主谓结构称之为宾语从句.也就是说,只要是用一个主谓结构去充当宾语,那么这个主谓结构就称为宾语从句. 例如: I believe that he will find a job in that publisher .(作谓语动词的宾语)我相信,他一定会在那家出版社找到工作. He laughed at what they said . (作介词的宾语)她对他们说的话,一笑置之. 要点提示在使用宾语从句中,有几个问题值得我们注意: 1)宾语从句与主句的时态一致性问题这种一致性的要求,只有当主句的谓语动词用于"过去时区"的时候才存在.凡是在"过去时区"内的各种不同时态都在其中.另外,这种一致性只要求宾语从句的谓语动词也用于"过去时区"即可,至于用什么样具体的时态就要依从句的需要而定了. He had told me that he would join the club sometime . 他曾经告诉我说,他会在某个时候参加俱乐部的. I remembered that I had met him somewhere . 我记得我曾在哪儿见过他. She thought that she would have finished what she was doing by the end of the month . 她认为在那个月底她将完成她手头上做的事. 2)if引导的宾语从句不能作介词的宾语,而只有用whether引导才行.这一点在上面刚刚讲过.(略) 3)某些动词后面,宾语从句的谓语要求用虚拟式.这一点已在"虚拟语气"一章中讨论过了,本章只作简单的复习.这类要求宾语从句的谓语用虚拟式的动词,常见的有:command(命令), demand(要求), desire(希望), insist(坚持), order(命令), propose(提议), recommend(推荐), request(要求), require(要求), suggest(建议),等.例如: He proposed that we ( should ) set a dead line for the complement of the plan . 他提议拟定一个执行计划的期限. C 表语从句在句子中担当表语的主谓结构称之为表语从句.它常位于句中联系动词或是起联系动词作用的动词之后.例如: The problem is where we can hold our meeting . 问题是我们可以在哪儿举行会议. It seems that everything goes smoothly .似乎一切都进行得很顺利. The cause is that the temperature of water is lower that needed . 其原因是水的温度低于所需要的温度. That is what he really wants .那就是他真想要的东西. D 同位语从句同位语从句就是在句子中担当同位语的主谓结构.在使用同位语从句时要特别注意:尽管主从连词that在同位语从句中没有任何意义,但却不能省略.另外,同位语从句常用于下面这些名词的后面(其中,斜体字的名词后面所接的同位语从句中要用虚拟语气): fact(事实), fear(担心、害怕), belief(信念,意见), evidence(证据), hope(希望), idea(想法) news(新闻), doubt(怀疑), suggestion(建议), motion(动议), proposal(提议), order(命令), recommendation(推荐),等等.例如: There is the news that an American delegation will arrive in Beijing tomorrow afternoon . 有消息说一个美国代表团将于明天下午抵达北京. Is there any proof that the food of the plant differs from that of animals ? 是否有任何证据可以说明植物性的食物不同于动物性的食物呢? We all know the fact that organization helps memorization. 我们都知道这样一个事实:把要记忆的材料组织起来有助于记忆. What do you think of his proposal that we ( should ) put on a play at the English evening ? 他建议我们在英语晚会上演一个剧,你觉得怎么样?

    延续性动词

    延续性动词表示行为或过程能持久地继续下去或能产生持久的影响.这类动词有:contain,have,hold, lie,live,make,sit,rain,sleep,stand,study,wait, wear,work等.此外,表示状态、感情、思维等动词,如:believe,consider,hate,hope,know,like,love,respect,think,understand,wish等也属延续性动词.要表示状态和延续性动作时必须要用延续性动词.如:

    错:This book has been put on the desk for a week.

    对:This book has been lying on the desk for a week.

    这本书已经在桌子上放一个星期了.

    错:Men put on suits when they attend meetings.

    对:Men wear suits when they attend meetings.

    男人在开会的时候穿西装.

    类似问题3:while的具体用法[英语科目]

    【while的用法】

    (1)引导时间状语从句,从句中的谓语动词应用延续性动词或表示状态的词.

    eg.While the discussion was still going on,George came in.

    当讨论还在进行时,乔治走了进来.

    Strike while the iron is hot.

    趁热打铁.

    ★注意:while,when,as表“当……的时候”的区别

    while强调同时性或某时间段内一种情况发生时另一种情况出现,与延续性动词连用;when可与延续或非延续性动词连用,在强调“当时”,“这时”之意时when;as强调同时性,指“一边……一边……”一件事情发生,另一件事情立刻发生.

    eg.———I’m going to the post office.

    ———______you’re there,can you get me some stamps?

    A.As B.While

    C.Because D.If

    解析:从该题的题意可以看出C、D两选项不合题意;而as侧重同时性,不合题意;while可指一时间段发生某情况时,另一情况出现,正合题意.

    (2)引导让步状语从句,多用于句首.意为“尽管,虽然”.

    eg.While I admit his good points I can see his bad.

    尽管我承认他的长处,但我也看到了他的不足.

    While he loves his students,he is very strict with them.

    虽然他爱他的学生,可是他对他们很严格.

    (3)While作并列连词用,意思为“而,然而”,表前后意义上的对比或转折.

    eg.There’s plenty of rain in the southeast,while there's little in the northeast.

    东南部雨量充足,而西北部则很少下雨.

    Some people waste food while others haven't enough.

    有些人浪费粮食,然而有些人却吃不饱.

    eg.She thought I was talking about her daughter,_______,in fact,I was talking about my daughter.

    A.whomB.where

    C.whichD.while

    解析:句意为“她认为我在谈她女儿,而实际上我在谈我的女儿.”whom,which和where分别是引导定语从句的关系代词和关系副词,后一句并非修饰定语从句,故应排除A、B和C选项.

    ★注意:while与but的区别

    二者都有“而,然而”之意,但while强调二者的对比,而but强调前后的转折关系.

    (4)引导条件状语,意思是“只要”

    eg.While there is a will,there is away.有志者事竟成.

    We can surely overcome these difficulties while we are closely united.

    只要我们紧密地团结一致,一定能克服这些困难.

    (5)while从句中的省略.当while从句中的主语与主句的主语一致,且含有be的某种形式时,从句中的主语连同be可同时省略.

    eg.While listening to the radio,she fell asleep.

    她在听收音机时睡着了.

    While in London,he studied music and painting.

    在伦敦时,他学习音乐和绘画.

    (6)while可用作名词,意为“一会儿;一段时间”

    作名词用时,主要用于短语中:afterawhile“过了一会儿”;allthewhile“一直,始终”;ashort/littlewhileago“刚才”;onceinawhile“偶尔、间或”;wait/rest(for)awhile“等/休息一会儿”.

    I haven’t seen her for along while.

    我好久没有看见她了.

    He usually goes to work by bike,but once in a while he goes by bus.

    他通常骑自行车上班,但偶尔也乘公共汽车.

    类似问题4:While的一些用法.While I () with my fiend,she came in.A:am taling B:was talking C:talked D:am going to talking

    While I () with my fiend,she came in.A:am taling B:was talking C:talked D:am going to talking

    选B

    用过去进行时

    翻译

    但我在和我朋友说话的时候,她进来了

    while引导的时间状语从句,长动作用进行时,短动作用一般时

    类似问题5:关于while的用法可以详细解释一下while的用法,并且告诉我什么情况下后面的动词要用_ing形式![英语科目]

    while 的用法:

    1)用在表示进行时态的句子中:

    如:While he was doing homework,Jim came in.

    2)用在两个动作同时进行的句中:

    如:While he was dancing,Jim was singing.

    3)表示对比,但没有发生转折:

    如:While he is a student,she is a teacher.

    4)表示状态:

    如:While he was at home,he finished his homework.

    总之,只要句中出现了Be动词,不管句子的意思如何,表示"当"这个意思的时候,正式场合都用"while".
