credentials.当你申请工作时，你必须递交你的有关证书。Mary made coffee while her guests were finishing their meal.客人们就要吃完的时候，玛丽去煮咖啡了。As he grew older，he became less active.随着他逐渐长大，他变得不那么活泼了。如果主句表示的是短暂性动作，而从句用延续性动词的进行时表示在一段时间内正在进行的动作时，when，while与as可互换使用。When/While/As I was walking down the street，I came across an old friend.我正沿着大街走时，碰巧遇到了我的一个老朋友。

have been living very happily since they got married.自从结婚后他们一直生活得很幸福。②since引导的从句的谓语若是持续性动词，常理解为某一状态的终止；若是终止性动词，则理解为某一动作的开始。He has written to me frequently since he was ill.自从病好以来，他经常给我来信。He has written to me frequently since he went abroad.他自出国以来，经常给我写信。③since表示“自从……以来”，常用于“It is/has been＋时间段＋since从句”结构。该句型表示“自从开始(不做)……已经多长时间了”，一般从句的时态用一般过去时，主句中的时态用现在完成时。As is reported，it has been/is over 100 years since Tsinghua University was founded.据报道，清华大学已经建立了100多年了。3．till，until和not...until...的用法。(1)until或till表示“某动作一直延续到某时间点才停止”，此时主句谓语动词是延续性动词，主、从句都为肯定式。这两个词可以换用，但till不可以置于句首，而until可以。Have you heard the meeting will be put off till/until next Tuesday?这个会议将被推迟到下周二，你有没有听说？(2)not...until...表示“直到……才”，主句谓语动词必须是非延续性动词。As far as I know，his mother won't go to bed until he returns home every evening.据我所知，他母亲每晚直到他回家才会上床睡觉。4．表示“一……就……，刚……就……”的常用表达。(1)表示“一……就……”的表达：as soon as，immediately，directly，the moment，the minute，the instantThe moment I heard the voice，I knew Father was

cheering.他刚完成演讲学生们就开始欢呼起来。(二)条件状语从句1．条件状语从句的常见引导词。if，unless(＝if...not)，so/as long as(只要)，on condition that(条件是)，if only(＝if)，provided that(如果)，in case(万一，如果)，suppose/supposing that(假设，如果)，assuming that等均可引导条件状语从句。①We will have a picnic in the park this Sunday unless it rains or it's very cold.除非下雨或天很冷，否则我们将在本周日去公园野餐。②My parents don't mind what job I do as long as I am happy.我的父母不在意我从事什么工作，只要我高兴就好。2．条件状语从句的时态。在条件状语从句中，常用一般现在时表将来含义；现在完成时表即将完成的情况；一般过去时表过去将来的含义。①If we work hard，we will find a way out.如果努力工作，我们会找到出路的。②If everyone does his part，the project will surely be a success.如果大家都尽责，这个项目肯定会成功。(三)让步状语从句1．although，though，while引导的让步状语从句。①Though/Although/While regular exercise is very important，it's never a good idea to exercise too close to

cannot.不管我们能否找到所需的工具，我们都要把这项工作做下去。(四)地点状语从句地点状语从句表示地点、方位，通常由where，wherever引导，可置于句首、句中或句尾。I cannot hear the professor clearly as there is too much noise where I am sitting.因为我坐的地方噪声太大，所以听不清教授在说什么。where引导的定语从句与状语从句的区别：地点状语从句与定语从句的区别在于从句在句中所作的成分，如果作状语，则是状语从句；如果作定语，则是定语从句。The little girl who got lost decided to remain where she was and wait for her mother.(状语从句，其中remain为不及物动词)→The little girl who got lost decided to remain in the place where she was and wait for her mother.(定语从句)那个迷路的小女孩决定待在原地等她的母亲。 (五)原因状语从句原因状语从句可由because，as，since，now that，in that，considering(that)等词引导。1．because译作“因为”，表示直接原因，语气较强，能回答由why提出的问句。The old man asked Lucy to move to another chair because he wanted to sit next to his wife.那位老人让露西换坐到另一把椅子上，因为他想挨着妻子坐。2．as译作“由于”，语气较轻，常表示显而易见的原因；since(既然)，now that(既然)，in that(因为)，表示双方都知道的原因，语气较弱。as，since和now that引导的从句多位于主句之前。Now that you have got a job，you should learn to be independent of your parents.既然你找到了一份工作，你就应该学会独立不依靠父母。(六)方式状语从句引导方式状语从句的从属连词有as，as if，as though等。方式状语从句应放在主句之后。其中as if或as though引导的从句常用虚拟语气，但如果从句中所陈述的情况很可能实现，也可用陈述语气。①The house was greatly damaged by the truck.We'd better leave things as they are until the police arrive.这辆卡车对这座房子造成了严重的损坏。我们最好保持原样直到警察到来。②The construction industry is no longer as depressed as it was.建筑业不再像以往那样萧条了。③The old lady treats the boy as if he were her own son.这位老太太对待这个男孩就像他是她自己的儿子似的。(七)结果状语从句1．引导结果状语从句的从属连词有：so...that...，such...that...。在非正式语体中，由so...that...，such...that...引导的句子中的that可以省略，注意其结构形式：eq \b\lc\{(\a\vs4\al\co1(so＋形容词/副词＋that从句,so＋形容词＋a/an＋可数名词单数＋that,从句,so＋many/much/few/little（少）＋名词＋,that从句))eq \b\lc\{(\a\vs4\al\co1(such＋a/an＋形容词＋可数名词单数＋that,从句,such＋形容词＋可数名词复数/不可数名词,＋that从句))①He is

park.天气如此晴朗，以至于我们都想去公园。③He earned so little money that he couldn't support his family.他挣这么少的钱，以至于养不起家。2．当so或such所在的主句主语与结果状语从句中的主语一致时，还可简化为：so/such...as to...。He was so clever a student that he was able to work out all the difficult problems.＝He was so clever a student as to be able to work out all the difficult problems.他是一名如此聪明的学生，以至于他能够解决所有难题。(八)目的状语从句引导目的状语从句的从属连词有：so that，in order that，for fear that，in case(that)，lest等。1．in order that和so that引导的目的状语从句。两个连词都意为“以便……；为了……”，它们引导的状语从句中常用情态动词。When he goes out，he often wears sunglasses so that/in order that nobody/no one can recognize him.他出门的时候常戴着墨镜，以便没人能认出他。2．for fear that，in case(that)和lest引导的目的状语从句。引导目的状语从句时，for fear that表示“害怕，担心某事会发生”；in case(that)/lest表示“以防出现某种情况”。①The boy hid himself behind the tree in case/for fear that his father should see him.那个男孩藏在树后面，以防他父亲看到他。②Larry told her that he had already put out the fire and she should not move in case she injured her neck.莱瑞告诉她他已经扑灭了火，她不应当动弹以免伤了脖子。[典型例题分析]1．Excuse me，________I have some news for you.but　[根据语境，句意为“不好意思打扰一下，但我有一些消息要告诉你们”。所以正确答案为but，but表转折关系。]2．Would you like a cup of tea ________shall we get down to business right away?or　[根据语境，句意为“你是想先喝杯茶还是我们马上就开始工作呢？”所以正确答案为or，or表选择关系。]3．—I don't like chicken ________fish.—I don't like chicken，________I like fish very much.or；but　[根据语境，前者想表达“我不喜欢鸡肉也不喜欢鱼肉”，后者想表达“我不喜欢鸡肉，但是我非常喜欢鱼肉”，所以正确答案为or；but。or表示选择关系，but表示转折关系。]4．—Do you mind I turn on the TV?—Go ahead.Let's watch the sports news now.if　[根据语境，作者想表达“——如果我打开电视，你会介意吗？——去开吧。让我们现在一起看体育新闻吧。”所以正确答案为if，if表条件意义。]5．________I was about seven years old，I took a trip with my father.When　[根据语境，句意为“当我大约七岁的时候，我和我的父亲去旅行”。seven years old表示一个时间点，需用when引导，所以正确答案为When。]6．I have dreamed of becoming a writer I was a teenager.since　[根据语境，句意为“当我还是青少年，我就梦想成为一名作家”。所以正确答案为since(自从)，since引导的从句用过去时，主句用完成时。][语法专项对练]Ⅰ.根据语境填入适当的连词1．He was very

English？This is a question 1.that is not so foolish as it may seem，for I find that many students of English pay far more attention to the story than to the English.For instance，they care for 2.how the mystery in the story is solved，3.but do not remember a single sentence in the story and cannot tell 4.what preposition is used before a certain word in the speech of a certain character.Of course，if you want to know the story only，you need not bother about the language.5.But a student of English is different from a student of stories 6.or what is called the general reader.7.As you may also have learned from the above，you ought to read not only very carefully but also aloud till you learn the passage by heart 8.and can recite it as if it 9.were (be)your own.On the one hand，this will teach you many useful words and phrases；on the other hand，it will help you to avoid many errors 10．and faults in expression.BMy classmate Michael studied very hard 1.after he went to senior school.Every day he worked 2.until everyone left the classroom.He said he wouldn't stop trying 3.unless he got satisfying scores in his studies.Hard 4.as/though he tried，he made little progress，but he didn't lose heart at all 5.because he believed as long as he persisted he would succeed one day.6.As time went by，he made improvements in his studies and he was admitted to a university in Guangzhou at last. We had a get­together party 7.before we started our new life in university.8.Since everyone had got offers from universities，we had a very good time.When we stood 9.where we used to play and study，we couldn't help thinking of our happy old days.We believed we would never forget each other，10.wherever we would go or whatever we would do.Before we departed，though we seemed a little sadder than before，we still fought back the tears.连词含义及用法when“当……时候”，可与延续性动词或短暂性动词连用；从句动作可以发生在主句动作之前、之后或与主句动作同时发生while“当……时候”，一般只可与延续性动词连用，从句动作与主句动作同时发生as“一边……一边……”，常与延续性动词连用，从句动作与主句动作同时或几乎同时发生
