                                   状语从句


【本讲教育信息】[来源:学,科,网   Z,X,X,K]
一.  教学内容:
    状语从句

[学习过程]
                                   状语从句
    状语从句在句中相当于副词做状语,                又叫副词性从句。状语从句分为时间状语从句、
条件状语从句、地点状语从句、原因状语从句、目的状语从句、让步状语从句、结果状语
从句和      比较状语从句。掌握状语从句应当从引导词入手,注意引导词的词义,引导状语从
句的引导词都有词义,所以,了解引导词                 的意思尤为重要。引导词按意义分为九类:
    1)时间     when , as , while , till , until , before  , after , since 
    2)地点     where 
    3)原因     because , as , since , now that 
    4)条件     if , unless , once .  so (as)  long as . in case 
    5)让步     though , whatever (--ever  ) as  , even though  , even if 
    6)目的     so that   , in order that  
    7)结果     so ... that 
    8)比较     than  , as .. as  
    9)方式     as , as if 
一、时间状语从句
    (1)as、when、while   用法一览表。
     类别               作     用                        例      句
           as 表示“当……的时候”,往往               She came up as I was cooking.(同时)
           和  when/ while 通用,但它着重强
      as
           调主句与从句的动作或事情同时                 The runners started as the gun went 
           或几乎同时发生。                       off.(几乎同时)
           (at or during the time that )既可 It was raining when we arrived.(指
           以表示在某一点的时候,又可表                 时间点)
     when  示在某一段时间内,主句与从句                 When  we were at school, we went to 
           的动作或事情可以同时发生也可                 the library every day.(在一段时间
           以先后发生。                         内)
           while 意思是“当……的时候”或
                                          Please don’t talk so loud while others 
           “在某一段时间里”。主句中的
                                          are working.
           动作或事情在从句中的动作或事
                                          He  fell asleep while/when reading. 
     while 情的进展过程中发生,从句中的
                                          Strike while the iron is hot.(用 as 或
           动词一般要用延续性动词。在
                                          when 不可,这里的      while 意思是
           when 表示  a period of time 时,两
                                          “趁……”)
           者可以互换。
    练习:
    ①I made many friends _______________ I was at university.
    ②He listens to the radio ______________ he is driving to work.
    ③______-____ the Spring Festival drew near, the child became more and more excited.
    ④I was about to leave ________-_____ someone came to visit me.
                  中国现代教育网     www.30edu.com  全国最大教师交流平台

    ⑤He is very diligent _______________ his son is very lazy.
    (2)引导时间状语从句的连接词除上述外还有:
    1)till, not …  until …, until, before, since
    Don’t get off the bus until it has stopped.
    He waited for his father until(till)it was twelve o’clock.
    It will be five years before he returns from England.
    常用句型:It is/was/will be …before…要过多久才…… 
            It isn’t /wasn’t/won’t be…before…没有多久就……
    It will be another five days before we finish this task.
    It is not long before I forgot it all.
    练习:
    ①I explained the sentence for three times _____________ he understood me.
    ②Two weeks ______________ she got divorced, she left her hometown to start a new life.
    ③Don’t get off the bus ______________ it has stopped.
    2)hardly / scarcely … when, no sooner … than, as soon as, once 表示“一……就”
    As soon as I hav e finished it, I’ll give you a call.
    Once you show any fear, he will attack you.
    We had hardly got / Hardly had we got into the country when it began to rain.
    No sooner had he arrived / He had no sooner arrived than she started complaining.
    3)directly, immediately, the moment, the minute that… 一……就
    He made for the door directly he heard the knock.
    4)each time, every time, by the time(到……为止)
    Each time he came to my city, he would call on me.
    注意:表示未来情况,主句用将来时,从句用现在时。

二、让步状语从句
    (1)although 与  though 可以引导让步状语从句,不能与            but 连用,但可以与      yet 连用。

    Althoug h they are poor,(yet)they are warm-hearted.
    (2)even   if 或 even though 引导让步状语从句,表示“即使”,“纵然”,用来使人
注意下文所强调内容的性质。
    I’ll get there even if(though)I have to sell my house to get enough money to go by air.
    (3)no    matter 后接上 who、what、where、how    等疑问词,也可以在这类疑问词后面
加上   ever 构成 whoever、whatever、wherever、however 等。
    Don’t trust him, no matter what / whatever he says.
    Whoever breaks the law will be published.
    No matter how hard the work is, you’d better try to do it well.
    (4)as  也可以引导让步状语从句。要用倒装。
    Child as(though)he is, he knows a lot.
    Much as I lik e it, I won’t buy.
    Try as he would, he couldn’t lift the heavy box.

三、原因状语从句:because, for, as, since, now that
    (1)表示不知道的原因时用            because,即说话人认为听话人不知道,因此             because 从句
                  中国现代教育网     www.30edu.com  全国最大教师交流平台

是 全句最重要的部分,通常它被置于主句之后。
    You want to know why I’m leaving? I’m leaving because I’m full.
    for 虽然表示不知道的原因,但其语气较              because 要弱得多,是可说可不说的话,它只
能置于主句之后,这时,for          是并列连词。如果不是因果关系,而是对前面主句的内容加以
解释或推断时,只能用          for。如:It’s  morning now, for the birds are singing.(很显然,鸟叫
不可能是“现在已是早上           ”的原因。)
    (2)表示已经知道的原因时用             as 或 since,即某种原因在说话人看来已经很明显,或已
为听话人所熟悉,因此它是句中不很重要的部分。since                    要比   as 正式一些,它们通常被置
于语句之前,但有时却相反。
    Seeing all of the children already seated, he said,“Since everyone is here, let’s  start.”
    (3)下列情况下只能使用           because:
    1)在回答    why 的问句时;
    —Why did you leave in such a hurry?  ---Because I had something urgent to deal with.
    2)在用于强调句型时;
    3)被  not 所否定时。
    练习:
    ①—I’ve decided to go abroad next year, darling, what about you?
    —Well, ___________ you’re going, so will I.
    ②—He must have gone to bed, _________________ it is dark in his room.
    ③It was _____________ I lacked money that I was forced to give up the project.

四、地点状语从句:where, wherever
    Mak e a mark wherever you have any questions.
    We will go where the Party directs us.

五、目的状语从句:tha        t, so that, in order that
    注意:目的状语从句的谓语动词常与情态动词连用,否则可能是结果状语从句。不可
置于句首。
    Let’s take the front seats (so) that we may see more clearly.
    School was closed early in order that the children might go home ahead of the storm.

六、结果状语从句:that, so that, so … that, such … that …
    注意:so +   形容词/副词     + that 从句;such + 名词    + that 从句。
    What has happened that you all looked so excited?
    Jenny is such a clever girl that all the teachers like her very much.
    =Jenny is so clever a girl that all the teachers like her very much.

七、方式状语从句:as, as if(th      ough)
    I’ll do as I am told to.
    It looks as if it is  going to rain.

八、比较状语从句:than(比), as(与…一样)
    It rains more often in Shanghai than in Beijing.
    The result was not as/so good as I had expected.
                  中国现代教育网     www.30edu.com  全国最大教师交流平台

    常用句型:the+比较级,the+比较级
    T he busier he is, the happier he feels.

九、条件状语从句:if, unless, so     (as)   long as, in case, once, a far as, on condition that.
    As/ So long as we don’t lose heart, we’ll find a way to overcome the difficulty.
    We’ll let you use the room on condition that you keep it clean and tidy.
    As/ So far as I know, he is an expert on DNA.
    注意  if 与 unless 的区别:不能用     and 连接两个    unless 从句,即不能有…       unless …,and 
unless … 。但  if … not and if … not 却不受此限制。
    You won’t lose your weight unless you eat less and unless you exercise more.(×)
    但可以说     … unless you eat less and exercise more.

十、注意状语从句中从句的省略现象
    (1)连接词      + 过去分词
    Don’t speak until  spoken to.
    Pressure can be increased when needed.
    Unless repaired, the washing machine is no use.
    (2)连词     +现在分词
    Look out while crossing the street.
    (3)连词     + 形容词/其他


    常见的有    it necessary、if possible、when necessary、if any 等。[来源:学。科。网]
