时间状语从句和原因状语从句专项练习资料

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。

1. 时间状语从句(1)时间状语从句常用when, as, while, before, after, since, till, until, as soon as等连词来引导。

例如：It was raining hard when got to school yesterday.While he was doing his homework, the telephone rang.As he walked along the lake, he sang happily.He had learned a little Chinese before he came to China.After he finished middle school, he went to work in a factory.(2)在时间状语从句里，通常不用将来时态，用现在时态表示将来的动作或状态。

例如：I’ll ring you up as soon as I get to New York.I will tell him everything when he comes back.He won’t believe it until he sees it with his own eyes.(3)在带有till或until引导的时间状语从句的主从复合句里，如果主句用肯定式，其含义是“一直到……时”，谓语动词只能用延续性动词。

如果主句用否定式，其含义是“直到……才……”, “在……以前不……”, 谓语动词可用瞬间动词。

状语从句状语从句在句中作状语，修饰主句中的动词、形容词或副词等。

状语从句放在主句之前时，常用逗号分开;放在主句之后，一般不用逗号。

状语从句按其意义和作用可分为时间、原因、地点、条件、让步、目的、结果、方式、比较等9种。

1.时间状语从句时间状语从句表示主句动作发生的时间，主要由when，while，as ; before, after; till (until); once, by the time, as soon as, no sooner ... than和hardly ... when及名词词组the moment等引导。

1) when“在……的时候”; while “在……期间”; as “正当……的时候”when意为“在……的时候”，强调“特定时间”。

When spring came, he felt like a trip.When he was eating his breakfast, he heard the doorbell ring.说明：连词when在状语从句中还有如下几种含义：①表示突然发生的事，含义为“（正在……时）忽然”。

I was just coming along to see you when I ran into Wilson.I had been working a couple of months when I had a letter from Jane.②表示过早发生某事，意为“（还没……）就”。

此含义有时可用before代替。

I hadn’t been reading for half an hour when I heard steps outside.我刚读了不到半个小时就听到外面有脚步声。

I had been there little more than a week when I set to work in earnest.③表示“在……的情况下”，常可译为“虽然”，“既然”，“如果”。

状语从句讲解与练习一、时间状语从句定义：用从句来表达一件事情或一个行为发生的时间(一) before & afterbefore：“在……之前”，主句动作发生在从句动作之前[主前从后]after：“在……之后”，主句动作发生在从句动作之后[主后从前]He called me after he finished his homework.He had learned English for three years before he went to London.(二)as soon as 一……就…… [主将从现]表示从句动作一发生，主句动作马上就发生。

I'll tell her everything as soon as she comes back.As soon as I reached Canada, I rang him up.(三) since 自从(1) 主句【现在完成时】+ since时间状语从句【一般过去时】He has gone abroad since he was 20.(2) It’s + 一段时间+ since时间状语从句【一般过去时】It is 10 years since we became friends.(四) until(1) 用于肯定句中，表示主句的动作一直持续到从句动作发生或状态出现时为止。

一般可译为“直到……为止”。

主句的动词必须是延续性的。

He will stay here until his mother comes back. [主将从现](2) until用于否定句中，表示主句的动作在从句的动作发生之后才开始。

一般可译为“直到……才……”或“直到……之前不要……” 。

主句的动词多为非延续性。

Don”t get off the bus until it has stopped.The little girl didn’t stop crying until she saw her mom.(五) when & while & as(1) 理论基础①三者都可表示“当……时”② while只接持续性动词，when/as持续、短暂都可以接③while 多用于进行时态，when多用于一般时态(2) 一般时while进行；进行when一般时The telephone rang while I was taking a bath.I was reading a newspaper when he came in.(3) 事件对比用while（然而；却）Father was preparing a report while I was playing PC games.He likes coffee while she likes tea.(4) “随着”/“一边…一边”用asThings are getting better and better as time goes on.She sang as she went along.二、原因状语从句because 因为（不与so连用）(1) because &because ofbecause引导原因状语从句because of 是介词短语，后跟n./pron./V-ing，句中作原因状语-- Why didn't he come here?-- He didn’t come here because he was ill.-- He didn’t come here because of his illness.(2) because & for & since & asbecause 语气最强烈；for放句中，用来表示一种附带或补充解释、说明；since & as 通常放句首，作“既然”讲。

什么是状语：句子中修饰动词、形容词等的句子成分叫状语，用来从地点、时间、原因、目的、结果、条件、让步、比较、方式和伴随状况等方面修饰说明谓语。

e.g. He speaks English very well（. 副词作状语）e.g. He is playing under the tree（. 介词短语作状语）e.g. I come specially to see you（. 不定式作状语）e.g. If I am not busy tomorrow,I will play football with you. （从句作状语）e.g. Having had a quarrel with his wife,he left home in a bad tempe（r. 分词作状语）状语从句：状语从句就是在复合句里起状语作用的从句，可以表示时间、地点、原因、目的、结果、让步、比较、方式、条件等。

引导状语从句的连词叫做从属连词。

状语从句的位置可以在句首，也可以在句末。

放在句首时，从句后面常用逗号与主句隔开；放在句末时，从句前面往往不用逗号。

If it ' s fine tomorrow, I lw gilo with you.I will go with you if it ' s fine tomorrow.状语从句分类：1、时间状语从句2、地点状语从句3、原因状语从句4、目的状语从句5、结果状语从句6、条件状语从句7、让步状语从句8、比较状语从句9、方式状语从句时间状语从句从属连词：when, while, as, before, after, till/until, since, whenever, as soon as（就）⋯⋯时态：主将从现，主情从现，主祈从现、When/while/as （当⋯时候）区别：主句动作与从句动作发生的时间（同时/之前/之后）；从句动词（延续性/瞬时性）1）When: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瞬间性动词，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。

状语从句的分类一、时间状语从句时间状语从句表示时间，引导词有：when, while, as, till, until before, after, since 等。

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时态、语态等问题。

注意： as（在⋯⋯时候，因为）， since （自从，因为），它们可以引导时间从句，并强调主句和从句的动作同事发生。

并且 while 有时还可以表示对比。

例如：（ 1）While my mother was reading the newspaper, I was watching TV.（read 是延续性的动词， read 和 watch 同事发生）I like playing football while you like playing basketball. 我喜欢踢足球，而你喜欢打篮球。

（对比）（2） when（当⋯⋯的时候），引导的从句的谓语动词可以是延续性动词，也可以是瞬间动词。

从句动作可与主语动作同事发生，也可在其后发生。

I was reading a book when she came into my room.（come 是瞬间动词，只能用 when 引导，不能用 while）I often missed my home when（while） I lived in NewYork. （ live 是延续性动词， when 可用while 代替）（ 3）when 和 while 的区别还在于： while 引导的时间状语从句多用于进行时态，而 when 引导的时间状语从句多用于一般时态。

While they were talking, the bell rang. 正在他们谈话的时候，上课铃响了。

（ 4）as 译作“一边⋯⋯一边”、“随着⋯⋯”，侧重主句和从句的动作同时发生。

有时可与when， while 通用。

高中时间状语从句及练习(含解答)状语从句是用来修饰主句中的动词、形容词或副词等的从句。

当状语从句放在主句之前时，通常需要用逗号分隔；而当放在主句之后时，则不需要逗号。

根据其意义和作用，状语从句可分为时间、原因、地点、条件、让步、目的、结果、方式和比较等九种类型。

1.时间状语从句时间状语从句用于表示主句动作发生的时间，通常由when、while、as、before、after、till (until)、once、by the time、as soon as、no sooner。

than和hardly。

when等引导词，以及名词词组XXX等构成。

其中，when表示“在……的时候”，强调“特定时间”。

例如：When spring came。

he felt like taking a trip.When he was eating his breakfast。

XXX.需要注意的是，连词when在状语从句中还有其他含义。

比如，它可以表示突然发生的事，含义为“（正在……时）忽然”；可以表示过早发生某事，意为“（还没……）就”；还可以表示“在……的情况下”，通常译为“虽然”、“既然”、“如果”等。

举个例子：I was just coming along to see you when I ran into Wilson.I hadn’t been reading for half an hour when I heard steps outside.She refuses help when (although) she has many friends.Why do you walk when (since) you have a car?How can I make them understand if they refuse to listen to me。

It's frustrating when you XXX。

状语从句（adverbial clause）复习要点：掌握句法功能，记住连接词语法意义：状语从句是复合句中的一种，整个从句作主句的状语，修饰主句中的谓语动词、形容词、或副词。

置于句首时，状语从句后面一般要有逗号隔开；如果状语从句置于句尾，则从句一般不用逗号。

按照所作的状语和意义可分为时间、地点、原因、目的、结果、条件、让步、方式和比较等九种状语从句。

具体如下：一、时间状语从句（Adverbial Clauses of Time）时间状语从句通常由when,whenever,as,while,before,after,assoon as,since,once,no sooner...then,hardly/scarcely...when,tiLl/until 以及the moment,directly,immediately,the second,thefirst time,next time,every time,等引导。

1.由when,as,while 引导的状语从句：1）when 引导时间状语从句，表示当···，其谓语动词可以是延续性的，也可以是非延续性的，其作用最广泛。

When spring comes,trees turn green,When it rains,I usually go to work by taxi.When we were having lunch,the light went out.I will ring you up when I return.When she pressed the button,the lift stopped.He was eating his breakfast when the doorbell rang.be about to do...when...“就在那/这时，（突然）另一个动作发生了，在这儿只能用when。

状语从句1.在主从复合句中修饰主句中的动词，形容词，副词等的从句叫状语从句。

可分为，时间状语从句，地点状语从句，原因，目的，结果，条件，让步，比较和方式状语从句。

2.时间状语从句起时间状语作用的句子；可放在句首，句中和句尾常用引导词：when，while, as, after, before, since, till, until, the moment, hardly … when , no sooner … thanwhen, while, as的用法1)when 用法最广，常可代替while和as, 在while 引导的从句中，动词只能是延续性的When the fire broke out, all the students were sleeping soundly.The telephone rang while I was taking a bath.2)当两个表示时间延续的动作同时发生而又有对比意味的时候，用while，在这样的复合句中，主句从句的时态通常是相同的。

Father was preparing a report while I was playing PC games.3)常用as 的情况：一边…一边；表示随着短暂动作的发生，另一行为伴随发生As he talked on, he got more and more excited.until和till的用法表示“一直到…”时，主句和从句都用肯定式；I will wait until/ till the concert is over.表示“直到…才…”是，主句用否定，从句用肯定式。

They can’t go until Sunday.since的用法since引导的从句中，如果是持续性动词，往往理解为某一状态的终止。

（完整版）状语从句练习状语从句状语从句：指把一句子当着副词作状语时，修饰动词、或整个句子；根据它在句中的作用可分为时间、地点、原因、条件、目的、结果、让步、方式和比较等从句；状语从句前一般由连词（从属连词）引导，也可以由词组引导。

它常位于句首；若位于句中，常用逗号与主句隔开；位于句尾时可以不用逗号隔开。

一、时间状语从句1. 通常由以下连词弓丨导：when / while / as/ after/ before/ as soon as/ since/ till /until / by the time2. 在时间状语从句中，要注意时态一致。

（主将从现）1）.when 当…..的时候: Mozart started writing music when he was four years old.2）.while 在…期间： He visited a lot of places while he was traveling.3）.as 在…的同时；一边…一边...: He smiled as he stood up.4）.after 在...之后: He left the classroom after he had finished his homework the other day.5）.before 在...之前Mr. brown had worked in a bank for a year before he came here.6）.as soon as 一...就... We bega n to work as soon as we got there. I will write to you as soon as i get home.7）.since 自...以来（至U现在） Mr green has taught in that school since he came to china three years ago.8）till /until 直至U : They walked till /until it was dark. Tom didn ' t leave home till / until his father came back.难点---- 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：as表示一边…一边"/随着，强调两个动作同时进行，I am cooking as I am singing.when 当…..的时候，从句动作可在主句动作"之前"或"之后"发生lit was raining hard when （as） i got there. 还可表and then; at that moment （正在那个时候/突然）：I am leaving for Beijing when the phone rang.while 在…期间从句动作为延续性动词或状态词I am cooki ng while I am si ngi ng然而（（表转折，对比）she thought I was talking about her daughter, while I was talking about my daughter.Mother was worried because little Alice was ill, especially as （when/ while） father was away.二、条件状语从句要点：状语从句由连词if （如果）、unless （=if not）（除非）弓I导。

第十二讲状语从句（含练习与答案）担任状语的从句叫状语从句，可以用来表示时间、地点、原因、目的、结果、条件、方式、比较、让步等。

一、时间状语从句：引导词有after，before，as，once，since，till，until，when，whenever，while，as soon as，the moment/minute…（一…就），the time, the day, every time, next time, each time，by the time ，no sooner…than（一…就），hardly(scarcely)…when（一…就）immediately/directly等．Each/Every time he comes here, he will drop in on me.He was ill last time I saw him.上次我见到他时他病了．Hardly had I got to the office when my wife phoned me to go back home at once.=No sooner had I got to the office than my wife phoned me to go home at once.I recognized him immediately I saw him.※ when, while与 as当主句动作时瞬时的，从句动作是延续的，三者都可以用。

when引导的从句动词可以是延续性的或短暂性的，在“be…when…”句式中when表“at that time(就在这时)”意。

while引导的从句中动词必须是延续性的；有时并不表示时间，而表示对比，意“而”、“却”，并列连词，表对照。

As 强调主、从句动作同时或几乎同时发生，意为“一边…一边…”。

When I got home I found the door locked.While / When / as we were working in the fields, it suddenly began to rain.He was wandering through the streets when a bike hit him.I was about to go out when the telephone rang.I had just arrived at school when my wife phoned me to go home.His pencil is red, while mine is yellow.John sang happily as he went along.※ till与until一般情况下可以互换，但until可以位于句首，till则不能。

状语从句状语从句在句中作状语，可分为：时间、条件、让步、原因、目的、结果、比较、地点、方式状语从句。

一、时间状语从句引导时间状语从句的连词有：when, as, while, until, not…until, before, after, since, the minute, the moment, each( every, next, the first) time等。

时间状语从句中一般用一般现在时或一般过去时。

1．When , while, as都可解释为“当```的时候”但侧重点有所不同。

1)WhenEg: When I arrived home , I had a little rest.注意点：when 从句的主语与主句主语相同，谓语动词是be 动词时，从句主语和be可以省略。

Eg: When (she was) walking along the street, she met her class teacher.2)AsAs 除了表示“当```的时候”，还可表示为“一面```一面”，“随着”Eg: He sang as he danced.(一面```一面)You will grow wiser as you grow older.(随着)3)While表示“当```的时候”强调主句的动作和从句的动作同时发生，从句一般用进行时，从句动词必须是延续性动词。

Eg: While we were working, they were having a rest.While (they were) having a discussion, they got very confused.注意点：while 有对比的含义，解释为“然而”。

eg: I prefer black tee, while he likes coffee.2．until, not…until表示“直到```才”,在肯定句中主句常用延续性动词；在否定句中主句常用短暂性动词。
