2014中考 .状语从句专题.doc

状语从句专题句法重点状语从句是中考词汇和句法部分考查的重点内容之一。状语的功用：状语说明地点、时间、原因、目的、结果、条件、让步等在复习状语从句时,主要任务是弄清楚引导各种状语从句的连词的用法。现就主要考查点简述如下:1.引导时间状语从句的连词主要有when, while, as, by the time, before, after, since, till/until, as soon as等。其中when while和as都可表示当时候,但用法有区别:when意为在时;当时,可表示点时间或段时间,从句谓语可以是终止性动词,也可以是延续性动词。例如:When I got home, he was having supper.as意为边边或与同时,重在表示两个动作同时发生。伴随进行。as从句是终止性动词时,主句通常也必须是终止性动词。例如:They sang as they danced.while只可表示段时间,从句谓语只限于延续性动词。例如:While I was sleeping, my father came in.注:从句谓语是持续性动词时,when、while和as可以互换2.引导原因状语从句的连词原因状语从句一般由because, since, as, for引导?注意as,because,since和for的区别:如果原因是构成句子的最主要部分,一般用because。because引导的从句一般不放在句子的开头。例如:I missed the train because I got up late.注:对于以why开头的问句,一般只能用because引导的从句来回答。如果原因已为人们所知,或不如句子的其余部分重要,就用as或since、since比as稍微正式一些。as和since引导的从句一般放在句子的开头。例如:As he was not well,I decided to go there without him.Since this method doesnt work, lets try another.for表示所说的理由是一种补充说明,因此,for引导的从句可以放在括号里,而且for引导的从句一般不放在句子的开头。例如:I decided to stop and have lunch, for I was feeling quite hungry.3.引导结果状语从句的连词主要有so/suchthat,so that等。1) so.that结构在某种情况下可以与enough to和too.to结构相互转换。例如:She is so short that she cant reach the buttons of the lift. =She is too short to reach the buttons of the lift.2)so that也可以引导结果状语从句,意为结果是;以致于。例如:They missed the bus so that they were late for class. so.that.”句型的意思是“如此/这么以致于”，常引导结果状语从句，但“so.that.”是个爱“变脸”句型，你一不留意就会出错。“so.that.”句型及其转换也是中考的热点，现将其用法总结归纳如下，让我们一起来看看它是怎样变的吧。 注意： so. that.句型中的so是副词，常常用来修饰形容词或副词，常用句型为：主语+谓语+so+adj. / adv. + that从句。例如： 1. he is so young that she cant look after herself. 2. The boy ran so fast that I couldnt catch him. 3. He was so angry that he couldnt say a word. 在“such. that.”句型中，such修饰名词，意思也是“如此以致于”但当名词前有many、much、(a) few、(a) little等词修饰时，句子中要用“so.that.”而不能用“such.that.”。例如： 1. He has so much money that he can buy what he wanted. 2. Ive had so many falls that I have pains here and there. 3. There is litte water in the glass that I cant drink any more.4引导目的状语从句的连词so that也可引导目的状语从句,此时可用to或in order to替换,将其改为简单句。例如:He got up early so that he could get to school on time. =He got up early to get to school on time. =In order to get to school on time,he got up early. 5. 引导让步状语从句的连词though, although注意： 当有though, although时，后面的从句不能有but，但是 though 和yet可连用 Although its raining, they are still working in the field.虽然在下雨，但他们仍在地里干活。 He is very old, but he still works very hard.虽然他很老，但仍然努力地工作。 Though the sore be healed, yet a scar may remain.伤口虽愈合，但伤疤留下了。 （谚语）6. 引导条件状语从句的连词要点： 表示状语从句由连词if, unless (=if not) 引导。1.If it doesnt rain tomorrow, we will go hiking.如果明天不下雨, 我们就去远足.2.You will get good grades if you study hard.如果你努力学习,就会取得好成绩.3.I will go to the party unless he goes there too.我不会去参加聚会的, 除非他也去.(如果他不去,我也不去.)难点提示：用条件状语从句时要注意时态的正确使用,当主句是将来时的时候,从句要用一般现在时. 7引导地点状语从句的连词(1)地点状语从句由where，wherever，引导，如： We must camp where we can get water. 我们必须在能找到水的地方露营。 （2）地点状语从句与定语从句的区别 where引导定语从句时，从句前应有一个表示地点的名词作先行词；而状语从句前则无需先行词。如： Go back where you came from.(where引导地点状语从句) 你从何处来到何处去。 Go back to the village where you came from.(where引导定语从句，修饰village) 回到你来的那个村子里去。 中考专练I. 选择填空：1.Ill let you know _ he comes back.A. before B. because C. as soon as D. although2.
