时间状语从句的引导词

when, before, after, as, while, till/until, since，whenever

时间状语从句的用法

时间状语从句的引导词所表示的意思不尽相同，要注意把握不同的时间状语从句的引导词所表示的不同时间关系，以及它在具体句子中对应的对应时态、语态等问题。

1. when、as、while引导的时间状语从句分析：

(1) when引导时间状语从句时表示“当……的时候”，when既可以指时间段也可指时间点，从句中既可用短暂性动词又可用延续性动词，且动作既可和主句的动作同时发生又可在主句的动作之前或之后发生。

注意体会如下例句：

I’ll call you when I get there.

我一到那里就给你打电话。

When the wind blows, all the doors rattle.

只要风一吹，这门就吱嘎作响。

When I came home my wife was cooking dinner. 我回家时，妻子在做晚饭。

如果when引导的时间状语从句的主语与主句主语相同，而从句的谓语又是be动词时，那么从句中的主语和be 可以省略;当when引导的时间状语从句的主语与主句主语相同时，往往还可以用“when+分词”的形式替代该状语从句。例如：

When (you are) in trouble, ask her for help.

当你遭遇麻烦的时候去向她求助。

When I came into the room (=When coming into the room), I found him lying there asleep.

当我进入房间的时候，我发现他躺在那儿睡着了。

(2) while引导时间状语从句时表示“当……的时候”，它强调主句的动作与从句的动作同时持续地进行，用于这一用法时while引导的时间状语从句和主句中的谓语动词必须是延续性动词，或者主句的动作发生在从句动作的进行过程中，主句中的谓语动词通常是非延续性动词，例如

Study while you study; play while you play.

该学习的时候就学习，该玩的时候就玩。

I met her while I was at school.

当我在学校的时候我遇见了她。

(3) as引导时间状语从句时表示“当……时，一边……一边……”，侧重表示两个动作同时发生(包括一个主语同时进行两个动作)，或者一种动作随着另一种动作的变化而变化。例如：

He jumps as he goes along. 他边走边跳。

I slipped on the ice as I ran home.

我跑回家时在冰上滑了一跤。

As the wind rose the noise increased.

刮风的时候噪声增大。

3. till和until 引导的时间状语从句分析：

Walk till you come to a white house.

一直走到一座白房子为止。

[答案] D

[考题10] I don’t really work here; I ____ until the new secretary arrives.

A. just help out

B. have just helped out

C. am just helping out

D. will just help out

[答案] C

[解析] “I don’t really work here”表明说话人只是临时前来帮忙，“until the new secretary arrives”表明说话人，工作到新秘书就任为止，本题应选用表示“到……为止”(跟主句里肯定形式的表延续性动作的谓语动词连用)的until表示这一时间关系。

4. since引导的时间状语从句分析：

since引导的时间状语从句表示“自从……以来”，其用法主要有两种：

(1) 现在完成时的主句+since引导的一般过去时态的时间状语从句。例如：He hasn’t been home since he graduated. 他毕业后没回过家。// They have been friends ever since they were in grade school. 他们从小学起就一直是好朋友。// What have you been doing since I last saw you? 自我上次和你见面以后，你在做什么?

(2) It be(主句中谓语用一般式和用完成式区别不大，后者更具强调意味)+表示一段时间的词汇+since引导的时间状语从句。例如：It is two years since I became a postgraduate student. 我成为研究生已经有2年了。It was three years since we had been there. 我们在那儿已呆了三年。

注意：since做介词时也表示“自从……以来”，其具体用法有两种情况：

(1) since+表示过去某个时间点的词汇(如具体的年、月、日期、钟点)。

例如：They have been friends since childhood. 他们从幼时起一直是好朋友。She’s been skiing since childhood. 她从幼时起就开始滑雪。I have been there many times since the war. 自那次战争以来，我曾去该地多次。

(2) since+表示一段时间的词汇+ago。

例如：I have been here since five months ago. 五个月以来我一直在这里。

[考题11] They ____ friends since they met in Shanghai.

A. have made

B. have become

C. have been

D. have turned

[答案] C

[解析] 题干中的since表示“自从……以来”，主句中的谓语动词应该表示从他们在上海相遇至今的持续性的动作，因此下划线处应填入可以表示持续性状态的have been(其他选项中的made、become、turned所表示的动作都不能延续，意味着结果)。

[考题12] —What was the party like?

—Wonderful. It’s been 2 years ____ I enjoyed myself so much.

A. after

B. before

C. when

D. since

[答案] D

[解析] since表示“自从……以来”。

①.when"当......时候"引导的时间状语从句，其动词既可以是延续性动作的动词，也可以是瞬间性动作的动词,如：

_________ the students heard the teacher's footsteps, they all stopped talking.

当学生们听到老师的脚步声时，他们都停止了讲话。(从句动作发生在前)

② as"当.......时候"或"一边.......一边"引导的时间状语从句其动词的动作是延续性的，而且侧重表示主句和从句的动作并相发生：

We were having breakfast __________ she was combing her hair.

她梳头时我们在吃早饭。

③ while表示"在某一段时间里"或"在……期间"，其所引导的从句的动作是延续性的，并侧重表示和主句的动作同时发生。如：

用when, as, while填空：

________ you came in, I was talking with a few boys.

It started to rain __________ we were playing outdoors.

(4) before引导的时间状语从句，指时间上的"在……之前"

(5) as soon as表示"一……就"，做题要注意主将从现

As soon as we __________ (get) there, he

___________ (tell) us the news.

我们一到那，他就会告诉我们那个消息。

We __________ never __________ (meet) since we ___________ (graduate) from the college.

大学毕业后我们就再没见过面。

(8) till/until引导的时间状语从句 till和until同义，作"直到……时(为止)"解，till多用于非正式文体，until多用于句首;not … until通常与after进行转换。如：

I won't go with you until(till) I finished my homework. =_________.

状语从句常用连接词归纳

状语从句常用引导词归纳 引导状语从句的词语叫从属连词。不同作用的状语从句通常由不同的从属连词来引导。如： 1. 引导时间状语从句的从属连词主要有when, while, as, whenever, before, after, since, until, till, as soon as, the moment, the minute, the second, the instant, immediately, directly, instantly, once等。 2. 引导条件状语从句的从属连词主要有if, unless, as [so] long as, in case 等。 3. 引导目的状语从句的从属连词主要有 in order that, so that, in case, for fear等。 4. 引导结果状语从句的从属连词主要有so that, so…that, such…that等。 5. 引导原因状语从句的从属连词主要有because, as, since, seeing (that), now (that), considering (that) 等。 6. 引导让步状语从句的从属连词主要有although, though, even though, even if, while, however, whatever, whoever, whenever, wherever等。 7. 引导方式状语从句的从属连词主要有as, like, as if, as though, the way等。 8. 引导地点状语从句的从属连词主要有where, wherever, everywhere等。 9. 引导比较状语从句的从属连词主要有than和as…as。 as long as和so long as引导条件状语从句的区别 as long as 和so long as 均可表示“只要”，用于引导条件状语从句，两者没什么区别。如： I don’t care so [as] long as she lets me be with her son.只要她让我和她儿子在一起，我不 在乎。 You can take my car as [so] long as you drive carefully. 你可以用我的汽车，只要你小心点儿开。 You may use my dictionary as [so] long as you don’t keep it too long.只要使用时间不太长，你可以用我的词典。

原因状语从句的引导词

because, since, as, now that，for之间的区别 because, as, for, since这几个词都是表示“原因”的连词，语气由强至弱依次为：because →since→as→for;其中because, since, as均为从属连词，引导原因状语从句；而for 是并列连词，引导并列句。 1. because表示直接原因，它所指的原因通常是听话人所不知道的，其语气最强。常用来回答why的提问，一般放于主句之后，也可以单独存在。例如： (1)I stayed at home because it rained. 因为下雨我呆在家里。 (2)Because Ling ling was ill, she didn't come to school. 玲玲因病，没有上学。 (3)—Why is she absent? 她为什么缺席？ —Because she is sick. 因为她病了。 ﹡此外，在强调句型中，只能用because。例如： (4)It was because I missed the early bus that I was late for school. 我上学迟到是因为我没有赶上早班汽车。 2. since侧重主句，从句表示显然的或已为人所知的理由，常译为“因为”、“既然”，语气比because稍弱，通常置于句首，表示一种含有勉强语气的原因。例如： (1)Since he asks you, you'll tell him why. 他既然问你，那就告诉他为什么吧。 (2)Since everyone is here, let's start. 既然大家都到齐了，我们就出发吧！ (3)Since I understood very little Japanese, I couldn't follow the conversation. 我日语懂得不多，因而听不懂对话。 3. as是常用词，它表示的“原因”是双方已知的事实或显而易见的原因，或者理由不是很重要，含义与since相同，但语气更弱，没有since正式，常译为“由于，鉴于”。从句说明原因，主句说明结果，主从并重。例如： (1)We all like her as she is kind. 我们都喜欢她，因为她善良。 (2)As I had a cold, I was absent from school. 因为我感冒了，所以没去上课。 (3)As Xiao Wang was not ready, we went without him. 由于小王没有准备好，我们只好不带他去了。 4. for用作连词时，与because相似，但它所表示的原因往往提供上文未交待过的情况。for 不表示直接原因，表明附加或推断的理由，因此for被看作等立连词，它所引导的分句只能放在句子后部(或单独成为一个句子)，并且前后两个分句间的逻辑关系不一定是因果关系，其间用逗号隔开，且for不可置于句首，for的这一用法常用在书面语中，较正式。例如： (1)The days are short, for it is now December. 白天短了，因为现在已是十二月份。 (2)It must have rained, for the ground is wet. (从“地面潮湿”作出“下过雨”的推测，但地湿并不一定是下雨所致, for不可以换为because。) (3)The ground is wet because it has rained. (“下雨”是“地上潮湿”的直接原因。) 前后两个分句间有一定的因果关系时(有时很难区分是直接原因，还是推测性原因)，for 与because可以互换使用。例如： (4)I could not go, for / because I was ill. 我没能去，是因为我病了。 (5)He felt no fear, for / because he was a brave boy. 他没有害怕，因为他是个勇敢的男孩。 1

状语从句的连接词及省略

状语从句连接词 时间状语从句：常用引导词：when, as, while, as soon as, before, after, since , till, until 特殊引导词：the minute, the moment, the second, every time, the day，the instant, immediately , directly, no sooner …than, hardly …when, scarcely … when instantly 地点状语从句:常用引导词：where 特殊引导词：wherever, anywhere, everywhere Generally, air will be heavily polluted where there are factories. Wherever you go, you should work hard. 地点状语从句一般由连接副词where, wherever等引导，已经形成了固定的句型: 句型1：Where＋地点从句，（there）＋主句。 【注意】此句型通常译成“哪里……哪里就……”；主句在从句后面时，there可用可不用；如果主句在从句的前面时，一般都不用there。例如： Where there is no rain, farming is difficult or impossible.在没有雨水的地方，耕作是困难的，或根本不可能的。 句型2：Anywhere/ wherever＋地点从句，＋主句。 【注意】anywhere本身是个副词，但是，常可以引导从句，相当于连词，意思相似于wherever, anywhere引导的从句可位于主句之前，也可以位于主句之后。而wherever本身就是个连词，表示“在何处，无论何处”。例如： Wherever the sea is , you will find seamen.有海就有海员。 原因状语从句:常用引导词：because=in that, since=now that(既然), as, for(补充说明) 特殊引导词：seeing that, now that, in that, considering that, given that（考虑到）. 目的状语从句：常用引导词：so that, in order that 特殊引导词：lest, in case, for fear that（唯恐生怕），in the hope that（带着..希望）, for the purpose that（带着..目的）, to the end that

WhenIcameintotheroom(=Whencomingintotheroom),Ifoundhi mlyingthereasleep. 当我进入房间的时候，我发现他躺在那儿睡着了。 (2)while引导时间状语从句时表示“当……的时候”，它强调主句的动作与从句的动作同时持续地进行，用于这一用法时while引导的时间状语从句和主句中的谓语动词必须是延续性动词，或者主句的动作发生在从 ，侧重 刮风的时候噪声增大。 [考题 1]Ihadjuststeepedoutofthebathroomandwasbusydryingmyselfwith atowel____Iheardthesteps.

You must attend the meeting unless (it is) inconvenient to you. (2)当状语从句的主语和主句的主语一致时,从句可以将主语和be动词简化掉。 a.连词+形容词 As (he was) young, he learned how to ride a bike. Whenever (she is) free, she often goes shopping. Work hard when (you are) young, or you'll regret.少壮不努力,老大徒伤悲。 b.连词+名词 While (he was) a young boy, he was always ready to help others.

时间状语从句引导词

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。

时间状语从句的引导词

时间状语从句的引导词 when, before, after, as, while, till/until, since，whenever 时间状语从句的用法 时间状语从句的引导词所表示的意思不尽相同，要注意把握不同的时间状语从句的引导词所表示的不同时间关系，以及它在具体句子中对应的对应时态、语态等问题。 1. when、as、while引导的时间状语从句分析： (1) when引导时间状语从句时表示“当……的时候”，when既可以指时间段也可指时间点，从句中既可用短暂性动词又可用延续性动词，且动作既可和主句的动作同时发生又可在主句的动作之前或之后发生。 注意体会如下例句： I’ll call you when I get there. 我一到那里就给你打电话。 When the wind blows, all the doors rattle. 只要风一吹，这门就吱嘎作响。

When I came home my wife was cooking dinner. 我回家时，妻子在做晚饭。 如果when引导的时间状语从句的主语与主句主语相同，而从句的谓语又是be动词时，那么从句中的主语和be 可以省略;当when引导的时间状语从句的主语与主句主语相同时，往往还可以用“when+分词”的形式替代该状语从句。例如： When (you are) in trouble, ask her for help. 当你遭遇麻烦的时候去向她求助。 When I came into the room (=When coming into the room), I found him lying there asleep. 当我进入房间的时候，我发现他躺在那儿睡着了。 (2) while引导时间状语从句时表示“当……的时候”，它强调主句的动作与从句的动作同时持续地进行，用于这一用法时while引导的时间状语从句和主句中的谓语动词必须是延续性动词，或者主句的动作发生在从句动作的进行过程中，主句中的谓语动词通常是非延续性动词，例如 Study while you study; play while you play.
