专题九  连词和状语从句基础知识过关　　在句子中作状语的从句叫状语从句。状语从句包括地点状语从句、方式状语从句、原因状语从句、目的状语从句、结果状语从句、条件状语从句、时间状语从句和让步状语从句。一、地点状语从句通常由where,  wherever 引导。Where there is a will,  there is a way. 有志者事竟成。二、方式状语从句通常由as,  (just) as. . . so. . . ,  as if,  as though引导。1. as引导的方式状语从句通常位于主句之后, 但在(just) as. . . so. . . 结构中, as引导的从句位于句首, 这时as从句带有比喻的含义, 意为“正如……, 就像……”, 多用于正式文体。When in Rome,  do as the Romans do. 入乡随俗。2. as if/as though两者的意义和用法相同, 它们引导的状语从句的谓语多用虚拟语气, 表示与事实相反, 有时也用陈述语气, 表示所说情况是事实或实现的可能性较大。常译作“仿佛……似的, 好像……似的”。He looks as if he had been hit by lightning. 他那样子就像被闪电击了似的。三、原因状语从句　　通常由because,  since,  as,  now that和for引导。1. because语气最强, 用来说明主要的直接的原因, 回答why提出的问题。当原因是显而易见的或已为人们所知时, 就用as,  now that或 since。I couldn’t call you because I didn’t have your number. 我没有你的号码所以不能给你打电话。Since there’s no more business,  we can all go home. 既然没有事情做, 我们都能回家了。2. for引导的从句不能直接说明某一特定动作发生的原因, 而只能提供一些起解释作用的附加说明。He took the food eagerly, for he had eaten nothing since dawn. 他狼吞虎咽地吃了起来, 因为他从天亮就没吃过东西。四、目的状语从句　　引导目的状语从句的词或短语有that,  so that,  in order that,  lest,  for fear that,  in case。　　I am saving money in order that I can buy a house. 我正在攒钱, 以便我能买一所房子。The thief carries a gun in case he is attacked. 小偷带着一把枪以防被攻击。五、结果状语从句　　常由so. . . that 或 such. . . that引导, 掌握这两个句型, 首先要了解so 和 such与其后的词的搭配规律。so+ adj. /adv. ; such+ a/an + adj. + n. ; such + adj. +复数名词或不可数名词。It was such an extraordinary story that no one believed a word of it. =It was so extraordinary a story that no one believed a word of it. 这个故事很不寻常所以没有人相信。六、条件状语从句　　引导条件状语从句的连接词主要有if,  unless,  as/so long as,  on condition that等。if 引导的条件句有真实条件句和非真实条件句两种。在真实条件句中常用一般现在时表示将来。例如: I’ll pay you double if you get the work finished by Friday. 如果你在星期五之前完成这项工作我会给你双倍的工资。七、时间状语从句　　引导词常有when, while, as, since, before, after, until, till, as soon as, the moment, every time等。1. when和while。when引导的从句中谓语动词可以是短暂性的也可以是延续性的, while引导的从句中的谓语动词必须是延续性的。I read the news while(=when) you were drying your hair. 在你弄干头发时我读了这些新闻。When he saw her,  he waved. 他一看见她就摆了摆手。2. since和before。since表示“自从”, 其所在的主句常用现在完成时; before表示“在……之前, ……才/就……, 还未来得及……就……”。How long is it since we visited your mother? 自从我们看望你母亲以来(到现在)有多长时间了? It will be a long time before we finish this dictionary. 我们需要很长的时间才能把这部词典编译完。八、让步状语从句　　引导让步状语从句的词有 though,  although, while,  as,  even if/even though,  no matter+疑问词, whoever,  whatever,  whichever,  however,  whenever,  wherever等。Although it’s raining,  (yet)they are still working in the field. 虽然在下雨, 但他们仍在地里干活。注意:  (1)当有though,  although时, 后面的从句不能有but, 但though/although和yet可连用。(2)as和though引导的让步状语从句可以用倒装, 其语序是: 表语/状语/谓语的一部分+as/though+主语+谓语。例如: Hard as/though he tried,  he failed. 尽管他努力了, 但失败了。(3)“no matter+疑问词”引导的让步状语从句可以与相应的whoever,  whatever,  whichever,  however,  whenever,  wherever互换。No matter where(=Wherever) you go,  I will remember you. 无论你去哪儿, 我都会记着你。 通关训练Ⅰ. 用适当的连接词完成句子1.
