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。

A. will leave B. is leaving C. leave D. leaves
专项训练状语从句练习题 一、初中英语状语从句 1．—Ling ling, you'll feel sleepy tomorrow _______ you go to bed early. —OK, Mom. I’ll go to bed at once. A．if B．unless C．though D．because 【答案】B 【解析】 【详解】 句意：——玲玲，如果你不早点睡觉，明天你会感到困的。——好的,妈妈。我马上去睡觉。 考查连词辨析。A. if如果，引导条件状语从句；B. unless如果不、除非，相当于if not，引导条件状语从句；C. though虽然、尽管，引导让步状语从句；D. because因为，引导原因状语从句。通过分析主从句之间的逻辑关系可知应该选择引导条件状语从句的从属连词if 或unless，再根据句子所表达的含义“如果不早点睡，明天就会感到困”可知unless符合语意，排除if；故答案选B。 2．—I’m afraid the class has begun.—Don’t worry. It ________ until the bell ________. A．does n’t begin; rings B．won’t begin; will ring C．won’t begin; rings D．doesn’t begin; will ring 【答案】C 【解析】 试题分析：句意：-恐怕课已经开始了。一不要担心。直到铃声响了才会开始。前面是主句，会议还没开始，所以用一般将来时；后面是until引导的时间状语从句，所以要用一般现在时代替一般将来时。所以选C。 考点：考查动词时态。 3．You'd better get home earlier today we can go out for a big meal. A．in order to B．such that C．so that D．in order 【答案】C 【解析】句意：你最好今天早点回家，这样我们就可以出去吃大餐了。A. in order to 为了，后跟动词原形；B. such that没有此用法；C. so that为了，引导目的状语从句；D. in order+that+从句，引导目的状语从句。we can go out for a big meal表示目的的完整句子，所以使用连词词组so that。故选：C。 4．________ there is danger on the internet, online insurance is still popular among the young. A．Unless B．Though C．Since D．Until 【答案】B 【解析】 【详解】
2.原因状语从句 原因状语从句表示主句中动作或状态发生的原因或理由, 可位于主句之前,之后或插在主句中间。主句表示结果, 从句表示原因, 主要由because, as, since, for, seeing ( that), considering ( that), now (that), in that, not ... because 等引导。 1) because“因为’’, as‘‘由于”, since “既然”, for“因为” because意为“因为”, 表示直接的原因或理由, 着重点在从句, 用于回答why,语气最强。 He is absent today because he is ill. 当主句为否定句时, 从句because须用逗号与主句隔开, 否则容易引起歧义。 I didn’t visit him, because I wanted to borrow some books. 我没去拜访他, 因为我想借几本书。 I didn’t visit him because I wanted to borrow some books. 我不是因为想借几本书才去拜访他的。 as意为“由于”, 表示十分明显的原因, 所引导的从句常位于主句之前, 有时也可位于主句之后, 一般说明因果关系, 着重点在主句, 原因或理由只是附带说明, 不用于回答why的问题, 常用于口语。 As it is snowing, we shall not go to the park. As this book is written in simple English, it is suitable for beginners. since意为“既然, 由于”时表示对方已知的、无须加以说明的既成事实的理由, 只是一个附带说明。since = as it is the fact that ...全句中心在主句。如从句表示的原因不是确定的事实, 就不能用since,通常用because. Since everybody is here, let’s begin our discussion. Since you seem to know them, why don’t you introduce me to them? for是一个并列连词, 由for连结的表原因的句子常看作并列句, 它只提供一些补充说明或对前一个分句加以解释, 不可前置。与because 不同的是:because引导的从句位置可前可后, 而for引导的分句只能后置, 且往往须用逗号或分号与前一个分句分开。 I didn’t go to see him, for a heavy snow was falling. The days were short, for it was now December. 有时, for引起的从句并不表示原因, 而是表示一种推断或解释, 而because则不能。 Someone in the house must be ill, for a doctor has just come out. He couldn’t have seen me, for I was not there. 一、填入恰当的连词 1. I didn’t go to school yesterday _________ I was ill. 2. ________ everybody is here, let’s begin our meeting. 3. ________ you are in poor health, you should not stay up late. 4. I asked her to stay to tea, ________ I had something to tell her. 5. ________ all the passengers are here, why don’t we start at once? 6. Bill won’t make any progress ________ he doesn’t study harder than before.
状语从句主要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 和特殊的连接词即考点。现分别列举如下: 1．时间状语从句 2 3 常用引导词：because,since,as,since 特殊引导词：seeingthat,nowthat,inthat,consideringthat,giventhat,consideringthat,? MyfriendsdislikemebecauseI’mhandsomeandsuc cessful. Nowthateverybodyhascome,let’sbeginourconference. Thehigherincometaxisharmfulinthatitmaydiscouragepeoplefromtryingtoearnmore. Consideringthatheisnomorethan12yearsold,hisheightof1.80misquiteremarkable.

Theteacherraisedhisvoiceonpurposethatthestudentsinthebackcouldhearmoreclearly. 5．结果状语从句 6 7 特殊引导词：as(用在让步状语从句中必须要倒装)，while(一般用在句首)，nomatter…，inspiteofthe factthat,while,whatever,whoever,wherever,whenever,however,whichever MuchasIrespecthim,Ican’tagreetohisproposal. 尽管我很尊敬他，我却不同意他的建议。Theoldmanalwaysenjoysswimmingeventhoughtheweatherisrough.

在复合句中，由从句表示的状语叫做状语从句。它可以用来修饰主语中的动词.形容词.副词等。根据它表达的意思，状语从句可以分为时间状语从句，地点状语从句，条件状语从句，比较状语从句，目的状语从句，结果状语从句和让步状语从句等。由连接词if或unless引导的状语从句叫做条件状语从句。在英文中，条件是指某一件事情实现之后（状语从句中的动作），其它事情（主句中的动作）才能发生，通常译作“假如”。（注意：在含有条件状语从句的复合句中，表示将来时态，主句是一般将来时态，从句要用一般现在时[主将从现原则]) [编辑本段] 条件状语从句的有关知识 语法引导条件状语从句最常用的连词是if,由if引导的条件状语从句表示在某种条件下某事很可能发生。如: If you ask him, he will help you.如果你请他帮忙,他会帮你的。 If you fail in the exam, you will let him down.如果你考试不及格,你会让他失望的。 另外,if从句还表示不可实现的条件或根本不可能存在的条件,也就是一种虚拟的条件或假设,从句多用一般过去时或过去完成时。如: If I were you, I would invite him to the party.如果我是你,我会邀请他参加聚会。 I would have arrived much earlier if I had not been caught in the traffic.如果没有堵车,我会到的早一点儿。 那么,除了if之外,是否还有其他连词也可以引导条件状语从句呢?回答是肯定的,不仅有,还有很多。这些词由于出现的频率较小,且用法较复杂一些,所以不如if为大家所熟知罢了。下面就这些词的用法以例句的形式进行一下简单总结。 1、unless conj.除非,若不,除非在……的时候 You will fail to arrive there in time unless you start earlier.如果你不早点动身,你就不能及时赶到那儿。 Unless it rains, the game will be played.除非下雨,比赛将照常进行。 2、on condition(that)...在……条件下,如果on condition (that)...引导的条件从句是主句事件发生的前提条件或唯一条件。 I can tell you the truth on condition that you promise to keep a secret.我可以告诉你真相,条件是你答应保守秘密。 You can go swimming on condition (that) you don't go too far from the river bank.你只有在不远离河岸的条件下才可以下水游泳。 3、supposing conj.如果,假如supposing引导的条件从句表示一种假设条件。 Supposing it rains, shall we continue the sports meeting?倘若下雨,我们的运动会还要继续举行吗?
