原因状语从句的用法
原因状语从句的用法
原因状语从句表原因，以下逐一介绍高考中常见的原因状语从句的引导词：
1. because引导的原因状语从句一般放于主句之后， because表示直接原因，语气最强，最适合回答 why引导的疑问句。例如： I do it because I like it. 我做这件事是
因为我喜欢。
注意：“not ... because”结构中的not否定的是because引导的整个从句，有时也否定主句例如： The country is not strong because it is large. 国强不在大。I
2. since引导的原因状语从句一般放于主句之前表示已知的、显然的理由(通常被翻译成“既然”)，较为正式，语气比because弱。例如： Since you are free today, you had better help me with my mathematics. 既然今天你休息，你最好帮我补习数学。
注意： seeing (that)， now (that)， considering (that)， in that这几个词汇与since引导的原因状语从句意思相近，都表示“既然”。例如： Seeing (that) he refused to help us, there’s no reason that we should now help him. 他既然曾经拒绝帮助我们，我们现在没有理由要来帮助他。// Now (that) you are grown up, you should not rely on your parents. 既然你长大了，就不应该依靠你的父母了。// Considering (that) everyb ody is here, let’s begin our discussion. 既然大家都到了，我们就开始讨论吧。// In that he is ill, he feels unable to do it. 因为有病，他觉得做不了那件
事。注意：
1. considering 和 given 还可用介词。如：
Considering his age, the little boy reads very well. 就他的年龄来说，这小孩读得
挺好的。
Given her interest in children, I am sure teaching is the right career for her. 考虑到她喜欢孩子, 我可以肯定教书是最适合她的职业。
2. 表示“因为”的连词不能与表示“所以”的 so 连用。如：
译：因为他病了，所以没有出席会议。
误：Because he was ill, so he didn’t attend the meeting.
正：He didn’t attend the meeting because he was ill.
正：He was ill so he didn’t attend the meeting
3. as 引导原因状语从句时表示附带说明的“双方已知的原因”，语气比since弱，较为正式，位置较为灵活(常放于主句之前)。例如：As it is raining, you’d better take a taxi. 既然在下雨，你最好乘出租汽车。// As you are tired, you had better rest.
既然累了，你最好休息一下。// I went to bed early, as I was exhausted. 我睡得早，
因为我筋疲力尽了。
4. for引导的原因状语从句并不说明主句行为发生的直接原因，只提供一些辅助性的补充说明， for引导的原因状语从句只能放于主句之后并且必须用逗号将其与主句隔开。例如： He could not have seen me, for I was not there. 他不可能见过我，因为我不
在那里。
［考题1］____ you’ve got a chance, you might as well make full use of it.
A. Now that
B. After
C. Although
D. As soon as ［答案］ A
［解析］主句与从句之间存在因果关系，且“you’ve got a chance”表示一个显而易见的原因，因此应选用表原因的now that。
［考题2］ He found it increasingly difficult to read, ____ his eyesight was
beginning to fail. (2006北京)
A. and
B. for
C. but
D. or ［答案］ B
［解析］“his eyesight was beginning to fail”是“he found it increasingly difficult to read”的原因，因此本题应选用可以表示原因的连词for引导原因状
语从句。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，从句中既可用延续性动词又可用非延续性动词，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。// He stopped trying, when he might have succeeded next time. 他不再试了，其实他可能下一次就成功。// 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。// I saw him as he was getting off the bus. 正当他下公共汽车时, 我看见了他。// As the wind rose the noise increased. 刮风的时
候噪声增大。
［考题1］ I had just steeped out of the bathroom and was busily drying myself with a towel ____ I heard the steps. (2006湖南)
A. while
B. when
C. since
D. after ［答案］ B
［考题2］ He was about halfway through his meal ____ a familiar voice came
to his ears. (2006辽宁)
A. why
B. where
C. when
D. while ［答案］ C
［考题3］ We were swimming in the lake ____ suddenly the storm started.
(2004北京春)
A. when
B. while
C. until
D. before
［答案］ A
［考题4］—I’m going to the post office.
—____ you’re there, can you get me some stamps? (1999)
A. As
B. While
C. Because
D. If
［答案］ B
［解析］主句中“get me some stamps”的动作发生在时间状语从句“you’re there”的过程之中，因此应选while表示这一时间关系(属于while引导时间状语从句的两大基本用法之一)。注意： as有时也可用于表示主句的动作发生在从句动作的过程中，但这一用法不是as引导时间状语从句的主要用法，表示主句的动作发生在从句动作的进行过程中时用while更为常见，因此B选项是最佳选项。
［考题5］ ____ the days went on, the weather got worse. (1990)
A. With
B. Since
C. While
D. As ［答案］ D
［解析］表示“the days went on”、“the weather got worse”两个相互伴随地进行变化的动作，应选as表示这一时间关系(while不适合用于这样的语境)。
［考题6］ Tom ____ into the house when no one ____. (1992)
A. slipped; was looking
B. had slipped; looked
C. slipped; had looked
D. was slipping; looked
［答案］ A
［解析］题干当中的when表示“当……的时候”， slip表示“偷偷地、悄悄地移动”，在本题中表示非延续性的动作——“溜进了教室”的结果，不适合用进行时态表示。第一个下划线处应填入slipped，以一般过去时客观描述在过去某一时间上发生的动作；look表示延续性的动作，可以持续进行，所以第二个下划线处应填入was looking，以
过去进行时描述汤姆溜进教室的大背景。
注意：如果主句的动作发生于表示“当……时”的时间状语从句中的动作的进行过程中，从句常用进行时。例如： The landlady suspected that someone must have broken into the house when/while/as she was watching TV show. 女房东怀疑在她看电视时曾有人闯入屋里。// When/While/As Tom was reading, Jim was arrested. 在汤姆看书的时
候，吉姆被逮捕了。
［考题7］ I ____ along the street looking for a place to park when the accident
____. (2006安徽)
A. went; was occurring
B. went; occurred
C. was going; occurred
D. was going; had occurred ［答案］ C
［解析］根据题干句子含义，事故发生于当我沿街行驶、寻找停车之处的时候；从句的动作发生在主句动作的过程中。主句的谓语动词go表示非延续性的动作，可以持续进行，应选用过去进行时的形式，从句的谓语动词为非延续性动词，应以一般过去时的形
式表结果。
2. before和after 引导的时间状语从句分析：
before引导时间状语从句时表示主句的动作发生在从句动作之前， after引导时间状语从句时表示主句的动作发生在从句动作之后。例如： See me before you leave. 在你离开之前来见我。// Before they drive any of the buses, they will have to pass a special test. 在驾驶公共汽车之前，他们必须通过专门测验。// I saw them after I arrived. 在
我抵达之后，我见到了他们。// I found his pen after he has left. 在他走后，我找
到了他的笔。
［考题8］ He was told that it would be at least three more months ____ he could
recover and return to work. (2007江西)
A. when
B. before
C. since
D. that ［答案］ B
［解析］表示“他康复并返回工作岗位之前至少还需要三个月”，［考题9］ It was some time ____ we realized the truth. (2005山东)
A. when
B. until
C. since
D. before
［答案］ D
［解析］题干意为：过了一段时间我们才意识到真相。下划线处应填入表示“在……
之前”的连词。
［考题10］—How long do you think it will be ____ China sends a manned spaceship
to the moon?
— Perhaps two or three years. (2006福建)
A. when
B. until
C. that
D. before ［答案］ D
［解析］下划线处所在的宾语从句采用一般将来时，题干中第一句话问将来某一活动
之前的时间， before最为适合。
［考题11］— Why di dn’t you tell him about the meeting?
— He rushed out of the room ____ I could say a word. (2006四川)
A. before
B. until
C. when
D. after ［答案］ A
［解析］根据题干中第一句话的提示，第二句话中的“he rushed out of the room”
发生于“I could say a word”之前。
3. till和 until 引导的时间状语从句分析：
till和 until这两个词作连词和介词时的意义和用法相同，一般可以换用(放在句首时通常用until的形式， till在口语中更为常见)。till和 until引导时间状语从句时跟主句里肯定形式或否定形式的、表示延续性动作的谓语动词连用表示“到……为止”，跟主句里否定形式的、表示非延续性动作的谓语动词连用表示“直到……才(开始)”，例如：Walk till you come to a white house. 一直走到一座白房子为止。// We didn’t discuss the problem until he came back. 我们一直等到他回来后才讨论问题。
［考题12］It is difficult for us to learn a lesson in life ____ we’ve actually
had that lesson. (2007天津)

［解析］题干的句子可以直译为：“在我们一生中，学到某个教训是困难的，直到
我们真正经历了这个教训为止。”
［考题13］ A good storyteller must be able to hold his listeners’ curiosity ____ he reaches the end of the story. (2003上海)
A. when
B. unless
C. after
D. until ［答案］ D
［解析］讲故事的人应该始终抓住听众的好奇心，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。
［考题14］ I d on’t really work here; I ____ until the new secretary arrives.
(1994)
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。
［考题15］ They ____ the train until it disappeared in the distance. (1998)
A. saw
B. watched
C. noticed
D. observed ［答案］ B
［解析］题干中的主句为肯定句， until需要跟主句里肯定形式的表延续性动作的谓语动词连用，因此本题应选表示延续性动作的watched(其他选项中的saw， noticed，observed所表示的动作都不能延续，意味着结果)。
［考题16］—Was his father very strict with him when he was at school?
—Yes. He had never praised him ____ he became one of the top students in his
grade. (2003北京春)
A.after
B.unless
C.until
D.when ［答案］ C
［解析］ until跟主句里否定形式的、表非延续性动作的谓语动词连用时，表示“直到……才(开始)”，本题应选until与主句中的“never praised”对应，表示“他的父亲直到他成为年级里的尖子生之一时才开始称赞他”。
［考题17］“You can’t have this football back ____ you promise not to kick it at my cat again,” the old man said firmly. (2006广东)
A. because
B. since
C. when
D. until ［答案］ D
［解析］题干中的直接引语较为复杂，根据“promise”的提示，该直接引语应表示一种假设，意为：你将不能拿回这足球，直到你承诺不再把它踢向我的猫。
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：

When you laugh and smile, your body relaxes. while 意为“在…的时候，在…的 同时”。While引导从句的 谓语动词必须是延续性While I was standing at the window, I saw several boys running along the street.
的，发生时间较长，并强调主句和从句的动作同时发生（或者相对应）。While 有时还可以表示对比。While John was watching TV, his wife was cooking. as 意为“一边…一边…”。As 引导的动作是延续性的， 发生时间较短，一般用于 主句和从句动作同时发 生；as也可以强调一前一 后。The writer was angry as he was travelling on a train to London because someone had invaded his “space”. He smiled as he stood up. after 意为“在…之后”。表示主句 动作发生在从句动作之 后。主句与从句的动作时 间关系与before引导的从 句相反。With many hungry visitors waiting, don’t stay too long at your table after you have finished. If an early exit is necessary, you can leave after a scene is over. before 意为“在…之前”。引导的从 句不用否定形式的谓语， 并且当before引导的从句 位于主句之后，有时译成 “就，才”。当主句用将来时，You can’t watch TV before you finish your homework. Before it ended, the theatre was almost empty. My father had left for Canada

状语从句用法讲解和练习汇编
第章状语从句 学习指导 状语从句在句子中作状语，用来修饰主句或主句的谓语。一般可分为九大类，分别表示时间、地点、原因、目的、结果、条件、让步、比较和方式。尽管种类较多，但由于状语从句与汉语结构和用法相似，所以理解和掌握它并不难。状语从句的关键是要掌握引导不同状语从句的常用连接词。现分别列举如下： 状语从句分九类： 在这一章节的学习中，要求同学们掌握各类状语从句基本概念，并能够灵活应用 第一节时间状语从句 1. 时间状语从句用一般现在时表示将来。连接时间状语从句的连接词有: 2. when，while，as均可表示当.... 的时候” when强调特定时间”表示主句谓语动词的动作与从句谓语动词的动作是同时发生的， 或从句的动作发生在主句的动作之前；while表示的时间是一段，而不是一点，as多用在口 语中，强调同一时间”或一前一后”有时还有随着”的含义。 I'll go on with the work when / come back tomorrow .我明天回来后会继续做我的工作。 When spring came, he felt like a trip.春天来了，他想去旅游。 As spring warms the good earth，all flowers begin to bloom . （as 有随着”的含义） as, when, while 都表示主、从句的动作或状态同时发生，但三者也有区别。as和when引导的从句既可表示一点时间，也可表示一段时间，从句中的谓语动词既可以是持续性动词，也可以为短暂性动词，经常可以互换使用；while引导的从句通常表示一段时间，从句中宜 用持续性动词作谓语。当从句中的谓语动词为持续性动词时，这三者可以通用（前面例句中 已有体现），再如： Mother was worried because little Alice was ill, especially as / when / while father was away in France. 妈妈担心，因为小艾丽思病了，特别是当父亲远在法国的时候。 如果从句和主句要表示一个人的两个动作交替进行或同时完成时，则多用as，可译为“一

语法讲解 时间状语从句的用法解析及练习
语法讲解时间状语从句的用法解析及练习 状语从句在复合句中作状语，其位置较灵活，可以在主句之前、之后或中间(放在句首时状语从句后面常用逗号，放在句末时状语从句前面往往不用逗号)。根据状语从句的含义，状语从句主要分为时间状语从句、地点状语从句、原因状语从句、目的状语从句、方式状语从句、结果状语从句、条件状语从句、让步状语从句等八种。掌握以上各种状语从句的关键在于把握其相应的引导词。以下是对时间状语从句的基本用法进行小结，希望可以帮助到同学们有一更深的理解。 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，从句中既可用延续性动词又可用非延续性动词，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。// He stopped trying, when he might have succeeded next time. 他不再试了，其实他可能下一次就成功。// 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。// I saw him as he was getting off the bus. 正当他下公共汽车时, 我看见了他。// As the wind rose the noise increased. 刮风的时候噪声增大。
