状语从句讲解及练习题50题

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 than l when, 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.They talked as they walked along the river.My cap was blown away as I sat down.l 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 cant go until Sunday.l 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。He has written to me frequently since he was ill. 自从他病好以来，他常写信给我。 Its been a year ever since I worked here. l 主将从现。时间状语从句一般不用将来时。因此如果主句是将来时，时间状语从句一般要用现在时。Well start when the team leader comes. l 一就 的几种常用的表示方法1） as soon asAs soon as he heard the news, he jumped with joy.2） ImmediatelyIll give you an answer immediately Ive finished reading your file.3） DirectlyDirectly you feel any pains, you must go to the doctor.4） InstantlyPlease give me a phone call instantly you arrive.5） no sooner thanNo sooner had I begun to talk than he rang offlI had no sooner begun to talk than then he rang off.6） hardlywhenHardly had I told him my name when he stopped listening.I had hardly told him my name when he stopped listening.3. 地点状语从句引导词 where, wherever, anywhere, everywhere,nowhere一般情况下，只要在where前面加上 to/in/from the place，就可以变为定语从句We live where the road crosses the river.We live in a place where the road crosses the river.4. 原因状语从句引导词：单词because，as, since 短语now that, for the reason that, in that, seeing thatl Because, as, since, for1） because 的语气最强，用以回答why 引起的提问，可表示已知或未知的世事。可与only ,merely, just ,not 连用，所引导的从句常用于主句之后，在表示强调的时候可置于主句之前（可用于强调结构）He was punished only because he broke the law.It was because that I went to town yesterday.2） as 的语气最弱,不可用于强调，常至于主句之前。As he was in a hurry, he left this bag home.3） since的语气也比较弱,常表示对方已知的事实，往往相当于汉语的既然。不用于强调。常置于主句之前。Since she cant answer this question, it is better to ask someone else.4） for连接并列句We should be more careful, for it is already dark.l now that用于口语，表示较弱的原因，主从句因果关系不明显。既然，that可省略。Now（that）you are grown up, you should not rely on your parents.l for the reason that后跟一个同位语从句。l that be happy that, be glad that, be surprised that 有时也被认为是原因状语从句l in thatThis experience is worth trusting in that it is based on scientific facts.l when（既然）I cant tell you anything when you wont listen.How can he succeed when he wont work?5. 目的状语从句l in order that /so thatI hurried through my work in order that I could be in time for wonderful TV programs.l for fear that Im working hard for fear that I should fail.l in caseI stayed all day at home in case you called.6. 结果状语从句l so thatso + 副词、形容词+that The text was so boring that I fell asleep.so+ many/few/much/little+thatHe has got so little money that his family had to live on welfare.so +动词+thatIt so happened that he didnt receive my invitation. l such thatsuch + a + 形容词+可数名词单数、复数+thatIt was such a terrible day that none of us would find an excuse for going out to play.They are such good children that we all love them.such+形容词+不可数名词+thatThis was such fine music that it was worth listening to twice.l That本身也可以引导结果状语从句What have we done that you should be so angry with us?7. 条件状语从句引导词：if, unless, as/so long as, once, in case, on condition that, supposing (that), providing (that), provided (that), given (that) 写作的时候，学会在文章里添加几个状语从句。Providing/Supposing/Given/Provided that you promise not to tell anyone else, Ill explain the secret.In case it rains, do not expect me. 如果下雨，就不要等我了。l 真实条件句与非真实条件句Unless you go at once, you will be late.If we had enough time yesterday, we could have done the work.其实属于一种虚拟语气。第一种是真实条件句，表示可以实现，第二句是非真实条件句，实现的可能性不大。8. 让步状语从句l Though和 although 基本相同，但是though可以当副词，although不可以Young though she is, she has travelled to many countries to put on shows.Ive bit of headache. Its nothing much, though.l Even though 和even if Even though the learning is slow and painful, the result is wonderful.Even if/ though you say so, I do not believe.l AsPop star as she is, she still needs to improve.Fail as I did, I would never give up.l whether () or not 和whether or l wh-ever类的用法引导名词性从句，只能用wh-ever，不能用no matter wh-I ll wait for you however late it is. = Ill wait for you no matter how late it is.9. 比较状语从句Asas not as/ so as , than , the +比较级， the+ 比较级His handwriting is not as good as yours (is).The sooner you are back, the better it will be.10. 方式状语从句l As 正如，像Will you please do the experiment as I am doing.l as if 和as though(1) 如果表述内容可能性很大，则用陈述语气 look/seem/taste /smell 等词连用It looks as if it is going to rain.(2) 表述的不是事实，则用虚拟语气The young man with long hair looks as if he were a girl.答案：15 DADBA 610 DCAAD 1115 BBAAD 1620 BCBDA 2125 BAABA 26-30 CDDDD 3135 CBBAA 36-40 BBABC 4142 BDCDC 46-50 CDDCD 1.
