Hardly had I got home when it began to rain. 我一到家就下起雨来。,2地点状语从句 通常由连词where和wherever引导，从句可位于主句之前，也可位于主句之后。如： Make a mark where you have any questions. 在你有问题的地方作个标记。,3原因状语从句 通常由because，since，as，now that，seeing (that)，considering that等引导。如： Seeing that its raining，wed better stay indoors. 既然下雨，我们最好待在室内。,Now that you have grown up，you must do it by yourself. 既然你已经长大了，就必须自己做这件事。 Considering that I have told you three times，you must know it. 鉴于我已经告诉你三次，你必须知道它。,4目的状语从句 目的状语从句通常由that，so that，in order that，so，for fear that，in case等引导。如： The teacher must speak clearly so that his students can understand well. 老师必须讲话清楚，学生才能理解得好。 Take your umbrella in case it should rain. 拿着雨伞，以防下雨。,(1)目的状语从句中的谓语常含有may (might)，can (could)，should，will等情态动词。通常主句在前，从句在后，主句与从句之间没有逗号。 (2)由that引导的目的状语从句现在用得较少，通常被so that或in order that所取代，in order that多用于正式文体中，so可用于口语或非正式文体中。如： Well sit near the front so (that) we can hear better. 为了听得更好我们坐得更靠近前台。,(3)在非正式文体中，常用in case，for fear that引导目的状语从句，表示“以防、以免”等。如： The boy hid himself behind the tree in case his father should see him. 这个男孩藏在树后，以防他爸爸看见。 He wrote the name down for fear that he should forget it. 他把名字记下来以防忘记。,5结果状语从句 通常由连词that，so that，so.that，such.that等引导。如： He had overslept，so that he was late for work. 他睡过头了，结果上班迟到了。 He was so angry that he left the room without saying a word. 他如此生气以致于什么也没说就离开了房间。,He made such an excellent speech that everyone admired him. 他做了个如此优秀的演讲以致于每个人都崇拜他。,6条件状语从句 通常由if，unless“如果不，除非”，as (so) long as“只要”，in case (that)“结果，万一”等连词引导。如： In case anything important happens，please call me up. 万一发生了什么重要事情，请打电话给我。 As long as you dont lose heart，you will succeed. 只要你有信心，你就能成功。,7方式状语从句 通常由as，as if，as though引导。如： You must do the exercise as I show you. 你必须按我给你展示的方式做练习。 as if，as though引导的状语从句，多描述非现实情况，应用虚拟语气，但口语中也有用陈述语气的。如：,The old lady treats the boy as if he were her own son. 老人对待这个男孩就像是自己的儿子一样。 He walked slowly as if(though) he had hurt his leg. 他走路慢得就像腿受伤了。,8比较状语从句 通常由as.as，not so (as)as，than等引导。如： His brother is as handsome as he(him) 他的哥哥像他一样帅。 The film was not so (as) good as I had expected. 这部电影比我期望得差。 He swims faster than any other student in his class. 他比班里其他任何同学都游得快。,9让步状语从句 通常由though，although，as(虽然，尽管)，even if，even though，whoever，whatever，whichever，whenever，wherever，however，no matter who(what，which，when，where，how)，whether等引导。 (1)由although，though，as引导的状语从句although和though同义，用法基本相同。前者较正式，多置于句首；后者较通俗、口语化。如：,He is unhappy though/although he has a lot of money. 尽管他有钱，但并不幸福。,as引导的让步状语从句多用于书面语，语序要倒装，它比用though或although引导让步状语从句更有表现力，语气更强。如： Difficult as the task was，they managed to finish it in time. 虽然这项任务很难，他们还是设法及时完成了。 Much as I like it，I wont buy the expensive car. 尽管我很喜欢这辆车，但我不会买这么贵的车。,though引导的让步状语从句，除了用于自然语序外，也可用于倒装语序，although则不可用于此句型。如： Clever though (as) you may be，you cannot do that. 尽管你可能很聪明，但你不能做那件事。,(2)even if，even though Even if he is poor，she loves him. 即使他很穷，她还是爱他。 Even though he is poor，she loves him. 尽管他很穷，但她还是爱他。,(3)由wh词ever引导让步状语从句。如： Keep calm，whatever happens. 不管发生什么都要保持冷静。 Whenever you call on me，you are always welcome. 不管何时你来看我，我都欢迎。,口语中常用no matter wh来代替whever引导让步状语从句。如： No matter what I did(Whatever I did)，no one paid any attention. 不管我做什么都没人关注我。,(4)whether引导让步状语从句 whether(.or)引导让步状语从句，提供两个或两个以上假设。如： Whether I go alone or he goes with me，the result will be the same. 我自己走还是他跟我一起走结果都是相同的。,1掌握连词意义，判断从句种类。 复习时，要熟悉每个连词的语意和语用特征，尤其像as，since这样用法灵活的词；像before，until，unless这样不易掌握的词；像as，when，while，since，because，if，in，case这些不易区分的词。要系统掌握状语从句的分类情况及各类状语从句中经常使用的连词。,技巧点拨,做题时，一方面要考虑句子逻辑意义的通顺，另一方面要考虑句子结构的完整，同时还要注意连词在句子中的位置。例如： There is a lot for Sam to improve _ he has achieved good results so far. Aeven though Bas though Cnow that Dso that,解析：句意：尽管到目前为止萨姆取得了不错的成绩，不过对他来说还有不少东西有待提高。even though“尽管，即使”，引导让步状语从句；as though“似乎，好像”引导方式状语从句；now that“既然，由于”，引导原因状语从句；so that“以便，为了，以致”，引导目的状语从句或结果状语从句。由题意可知选A项。 答案：A,2分析连词功能，掌握“疑问词ever”用法。 疑问词ever引导的让步状语从句可以换成no matter疑问词从句，但是疑问词ever结构除了可以引导让步状语从句外，还可以引导名词性从句，而no matter疑问词结构只能引导让步状语从句，在平时复习中应注意这两方面的区别。例如：,_you have picked up, yo
