状语从句状语从句在高考试题中由于其他从句的干扰，以及倒装句，强调句的介入，使得状语从句更为复杂状语从句是一种副词性从句，通常由一个从属连词或一个起连词作用的词组引导状语从句1 时间状语从句常见的连词(组)：when, while, as, befre, after, nce, till, until, as sn as, nw that, hardly when, scarcely when, n sner than等可以引导时间状语从句的副（介）词（短语）或名词短语：directly, instantly, iediately, by the tie, the ent, the secnd, the inute, the instant, every tie, each tie, net tie, the last tie等注意点如下：(1) when, while, as引导的时间状语从句as表示“当……的时候”，往往和when/ while通用，但它着重强调主句与从句的动作或事情同时或几乎同时发生when(at r during the tie)既可以表示在某一点的时候，又可以表示在某一段时间内，主句与从句的动作或事情可以同时发生也可以先后发生while强调一段时间，仅表示从句和主句的动作同时发生，并且有延续意义，该从句中的动词一般要用延续性动词，从句中常用过去进行时态或一般过去时态；当when表示a perid f tie时，两者可以互换She cae up as I was cing(同时)在我做饭时，她走了过When we were at schl, we went t the library every day(在一段时间内)当我们在学校时，每天都去图书馆While they were watching TV, I was preparing yself fr the cing eainatin他们在看电视，而我在为即将到的考试做准备Strie while the irn is ht 趁热打铁( 不可用as或when，这里的while意思是“趁……”)一、when可以和延续性动词连用，也可以和短暂性动词连用；而while和as只能和延续性动词连用① Why d yu want a new jb when yu've gt such a gd ne already？（get为短暂性动词）你已经找到如此好的工作，为何还想再找新的？②Srry，I was ut when yu called e．（call为短暂性动词）对不起，你打电话时我刚好外出了③Strie while the irn is ht．（is为延续性动词，表示一种持续的状态）趁热打铁④ The students t ntes as they listened．（listen为延续性动词）学生们边听课边做笔记二、when从句的谓语动词可以在主句谓语动作之前、之后或同时发生；while和as从句的谓语动作必须是和主句谓语动作同时发生1．从句动作在主句动作前发生，只用 when①When he had finished his hewr，he t a shrt rest．（finished先发生）当他完成作业后，他休息了一会儿②When I gt t the airprt，the guests had left．（gt t后发生）当我赶到飞机场时，客人们已经离开了2．从句动作和主句动作同时发生，且从句动作为延续性动词时，when，while，as都可使用①When ／While ／As we were dancing，a stranger cae in．（dance为延续性动词）当我们跳舞时，一位陌生人走了进②When ／While ／As she was aing a phnecall，I was writing a letter．（ae为延续性动词）当她在打电话时，我正在写信3．当主句、从句动作同时进行，从句动作的时间概念淡化，而主要表示主句动作发生的背景或条件时，只能用 as这时，as常表示“随着……”；“一边……，一边……”之意① As the tie went n，the weather gt wrse．（as表示“随着……”之意）② The atsphere gets thinner and thinner as the height increases．随着高度的增加，大气越越稀薄③As years g by，hina is getting strnger and richer．随着时间一年一年过去，中国变得越越富强了④The little girls sang as they went．小姑娘们一边走，一边唱⑤The sad ther sat n the radside，shuting as she was crying．伤心的妈妈坐在路边，边哭边叫4．在将时从句中，常用when，且从句须用一般时代替将时①Yu shall brrw the b when I have finished reading it．在我读完这本书后，你可以借阅②When the anager ces here fr a visit net wee，I'll tal with hi abut this．下周，经理这参观时，我会和他谈谈此事三、when用于表示“一……就……”的句型中（指过去的事情）sb．had hardly（＝scarcely） dne sth．when．．．＝Hardly ／ Scarcely had sb．dne sth．when．．．①I had hardly ／scarcely clsed y eyes when sene nced at the dr．＝Hardly ／ Scarcely had I clsed y eyes when sene nced at the dr．我刚一闭上眼，就有人在敲门了②I had hardly ／scarcely entered y r when the telephne rang．＝Hardly ／Scarcely had I entered y r when the telephne rang．我刚一走进房门，电话就响了(2) befre引导状语从句时的常见重点句型①It will (nt) be befre还要……才，要不了多久就……It was (nt) befre 过了……才(没多久就……)It was a lng tie befre I gt t sleep过了好长时间我才睡着了It wasn t lng befre he tld e abut the news没多久他就告诉了我那条新闻②不等……就……；在……之前就……The telephne rang ff befre I culd answer it我还没得及接电话，电话就挂断了③刚……就……He hardly entered the r befre he heard the telephne ring他刚进屋电话铃就响了④先……再……Yu can have a few days t thin abut it befre yu ae yur decisin做决定之前你还有几天时间考虑(3)since 引导的从句用延续性动词的过去式（包括过去完成时）时，则从句的动作已经结束,从句意思是否定的如果从句的动词是延续性动词的现在完成时态，则从句意思是肯定的He has never been t see e since I was ill我病愈后，他一直未看我（不再生病了）He has never been t see e since I have been ill我病了，他一直未看我I haven t heard fr hi since he lived here自他从这里搬走，我就没有收到他的信（不住在这儿了）(4) till, until如果till与until用在肯定句中时，则主句中谓语动词部分所表示的动作或状态一直延续到某时或某个动作发生时才结束注意它的倒装句和强调句I didn t recgnize she was y classate until she t ff her dar glasses=Nt until she t ff her dar glasses did I recgnise she was y classate=It was nt until she t ff her dar glasses that I recgnised she was y classate直到她摘下墨镜，我才认出她是我的同学2 原因状语从句引导原因状语从句的常见连词或短语：as, because, since, nw that, cnsidering that, seeing that(鉴于……)注意以下几点：(1) because, since, as, fr, nw thatbecause语气最强，用于回答why的提问，可与强调词nly, just 以及否定词nt 连用但不可以与s连用since 引导的从句语气次于because引导的从句，常表示稍加分析后而推断出的原因，或指人们已知的事实，比as正式一些,常置于句首as 语气最弱，其原因只是对结果的附带说明，一般放在句首fr虽然解释为“因为”但只是一个并列连词，它也常引导句子表示原因，但不是原因状语从句，它是一个并列句fr所提供的理由是一种补充性的说明，表示推测的理由nw that意为“既然，由于”表示由于人们已知的事实或正在发生的事而产生某个结果He failed because he was careless他因粗心而失败了Since everyne has ce, let s begin ur eeting既然大家都了，我们开会吧As all the seats were full, he std there所有的座位都满了,他只好站那儿It ight have rained last night fr the grund is wet昨晚可能下雨了，因为地面是湿的Nw that the ids have left he we have a lt f etra space由于孩子们离开了家，所以我们有了额外的空间3 地点状语从句地点状语从句常由下列连词引导：where, wherever等Yu ay find hi where his brther lives你可能会在他哥哥居住的地方找到他Yu are free t g wherever yu lie你可以去你想要去的任何地方Anywhere he went, he gt war welce无论他走到哪儿，都受到热烈欢迎The girl taes the dll with her everywhere she ges这个女孩无论去哪都带着她的布娃娃Where there is a will, there is a way 有志者事竟成4 结果状语从句结果状语从句常由下列连词引导：s that，such that，s that等要注意以下几个问题(1) 五种结构：①s+adj/adv+that②such (a/an+adj)+n+that③s+adj+a/an+n+that=such a/an+adj+n+that④s any/uch/few/little(少)+n+that⑤such+(adj) +n (u/pl)+ thatHe spe s fast that I culdn t fllw hi他说的如此的快，我跟不上他It was such a lvely day / s lvely a day that we all went swiing今天天气如此的好，我们大家都去游泳了(2) s或such置于句首时，主句常用倒装It was such a lvely day / s lvely a day that we all went swiing＝Such a lvely day was it that we all went swiing今天天气如此的好，我们大家都去游泳了(3)注意以上结构与定语从句s/such as的区别This is such an interesting/s interesting a fil that everyne wants t see it这是一部很有趣的电影以至于每个人都想去看5 目的状语从句目的状语从句由下列连词引导：s that, in rder that, fr fear that, in case等（注：s that也可用引导结果状语从句）s that, in rder that引导的目的状语从句中常需用情态动词s that引导的目的状语从句只能放在主句之后in rder that 引导的目的状语从句可以放在主句之前或之后We set ut early s that we culd see the sunrise我们很早出发以便能看到日出He sent the letter by air ail s that it ight reach the in tie他空邮这封信以便他们能及时收到6 条件状语从句条件状语从句分为真实条件句和非真实条件句（用在虚拟语气中）注意：在真实条件句中，常用一般时态代替将时常由下列连词引导条件状语从句：if, unless, suppse, suppsing, prviding (that), prvided (that), given (that), in case, n cnditin that, as lng as, s lng as, s far as等(1) unless=if ntYu will fail unless yu study hard除非你努力，否则你就要失败(2) suppse, suppsing, prviding(that), prvided(that), given(that)=

thugh引导让步状语从句时，主句前不能用but,但可以加yet, stillThugh it was raining hard, yet they didn t stp wring尽管下着大雨，他们仍然在工作(2) as引导让步状语从句时，必须用前置结构，通常是从句中的表语、状语或动词原形放在句首，放在句首的名词前的冠词要去掉Thugh he is a child, he nws a lt=hild as(thugh)he is, he nws a lt尽管他是个孩子，但他仍知道的很多（注意在child前不要用冠词）Thugh I lie it very uch, I wn t buy it=Much as I lie it, I wn t buy it尽管我非常喜欢它，但我也不会买它(3)whether r (nt )
