Lesson 55-59状语从句总结一、原因状语从句(1)原因状语从句通常由because, since, as, for引导。

(2)because表示直接原因，语气最强。

because引导的原因状语从句多放在主句之后。

回答由why提出的问题，只能用because。

此外，because和so不能同用在一个句子里。

例如：------Why aren’t going there?------Because I don’t want to.since引导原因状语从句，相当于now that，意思是“因为……，既然……，鉴于……”。

例如：Since the rain has stopped，let’s go for a walk. 既然雨停了，我们出去散散步吧。

as和since语气较弱，一般用来表示明显的原因。

由as和since引导的原因状语从居多放在句首。

例如：As he has no car, he can’t get there easily.Since we have no money, we can’t buy it.(4)for表示所说的理由是一种补充说明,for引导的从句一般不放在句子的开头。

如:I decided to stop and have lunch, for I was feeling quite hungry.练习：I was late for class yesterday _______ there was something wrong with my bike.He took off his coat _______ he felt hot.you c an’t answer the question, I’ll ask someone else.二、结果状语从句(1)结果状语从句由so…that, such…that, so that引导。

(2)so…that语such...that可以互换。

结果状语从句一．so... that...句型中的so是副词，常常用来修饰形容词或副词，意思是“如此……以致于……”，引导结果状语从句，常用句型为：主语+谓语+so+adj/adv+that从句。

例如：1. He is so young that she can't look after herself.2. The boy ran so fast that I couldn't catch him.3. He was so angry that he couldn't say a word.二、在“such... that...”句型中，such修饰名词，意思也是“如此……以致于……”，引导结果状语从句，其句型结构可分以下三种：1. such＋a(an)＋adj.＋单数可数名词＋that从句He is such a clever boy that everybody likes him.He was such an honest man that he was praised by the teacher.2. such＋adj.＋复数可数名词＋that从句They are such interesting novels that I want to read them once again.3. such＋adj.＋不可数名词＋that从句He has made such great progress that the teachers are pleased with him.【注意】如果such后边的名词前由many、much、few、little等词所修饰的话，则不用such 而用so。

例如：He had so many falls that he was black and blue all over.He had so little education that he was unfit for this job.4.so＋adj.或者adv＋(a + 名词单数）＋that从句三、以“so...that”引导的结果状语从句可以转换成不定式的简单句，即可转换为“...enough to...”或“...too...to”句型，但这种转换必须符合下列条件：1. 当主句和从句的主语一致，且that从句是肯定句时，可用“enough to do sth.”来转换。

状语从句知识讲解基本概念定义：在复合句中由从句表示的状语称作状语从句，它可以用来修饰谓语（包括非谓语动词）、定语或状语，或是整个句子。

状语句通常由一个连词引起，也可以由一个起连词作用的词组引起，有时甚至不需要连词直接和主句连接起来。

状语从句一般分为九大类状语从句类别时间状语从句地点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方式状语从句比较状语从句让步状语从句一、时间状语从句1．when, while和as1) when既可引导一个持续动作，也可引导一个短暂动作，可用于主句和从句动作同时发生或从句动作先于主句动作。

如：When I lived there, I used to go to the seashore on Sundays.When the film ended, the people went back.2）while引导的从句的谓语动词动作必须是持续的，侧重主句动作和从句动作相对比，同时while引导的从句一般用进行时。

如：While I was wondering at this, our schoolmaster took his place.3) as引导一个持续性动作，多用于主句和从句动作同时发生。

如：He hurried home, looking behind as he went.John sings as he works.4) when还可用作并列连词使用，其意义是“那时、这时”，相当于and this/that time.常用于下列句式：Somebody was doing someth ing when…Somebody was about to /going to do something/ on the point of doing sth. when…Somebody had just / hardly done something when…过去时此外when还表示原因“既然”。

Father was preparing a report while I was playing PC games.3)常用as 的情况：一边⋯一边；表示随着短暂动作的发生，另一行为伴随发生As he talked on, he got more and more excited.until 和till 的用法表示“一直到⋯”时，主句和从句都用肯定式；I will wait until/ till the concert is over. 表示“直到⋯才⋯”是，主句用否定，从句用肯定式。

They can't go untilSunday.since 的用法since 引导的从句中，如果是持续性动词，往往理解为某一状态的终止。

He has written to me frequently since he was ill. 自从他病好以来，他常写信给我。

状语从句总结一、原因状语从句(1)原因状语从句通常由because, since, as, for引导。
