原因、结果、目的状语从句讲解和练习和答案.doc

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 arent going there?-Because I dont 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，lets 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 cant get there easily. Since we have no money, we cant buy it.(3)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 cant answer the question, Ill ask someone else.二、结果状语从句(1)结果状语从句由sothat, suchthat, so that引导。(2)sothat语such.that可以互换。在由so.that引导的结果状语从句中，so是副词，与形容词连用。其结构是: “.so + 形容词（副词）+ that + 从句”。例如：He was so glad that he couldnt say a word. Mother lives so far away that we hardly ever（几乎不，从来不） see her.在由suchthat引导的结果状语从句中，such是形容词，它修饰的可以是单数或复数可数名词，也可以是不可数名词；其结构是: “.such +a / an + 形容词+名词+ that + 从句”。例如：It was such a hot day that nobody wanted to do anything.He had such long arms that he could almost touch the ceiling.（天花板） 有时上述两种结构是可以互换的。例如：It was such a wonderful film that all of us wanted to see it again.=The film was so wonderful that all of us wanted to see it again.(3)如果名词前由many, much, little, few等词修饰时，只能用so, 不用such。例如：Soon there were so many deer that they ate up all the wild roses.He has so little time that he cant go to the cinema with you.(4)如果主从句的主语相同，并且从句是否定的形式，可以用too.to.句型转化。例如：He was so excited that he couldnt go to sleep that night. = He was too excited to go to sleep.(5)如果主从句的主语相同，但从句是肯定的形式，可以用adj.+ enough替换。例如：He is so old that he could go to school. = He is old enough to go to school.他够大了，可以去上学。练习：It is _ hot in the room _ we have to go out for a walk.It was a wonderful movie all of us wanted to see it again. There were little water in the bottle the bird couldnt reach it. . 三、目的状语从句(1)目的状语从句通常由 so that, in order that（为了，以便）引导。例如：We started early so that we could catch the first train. We used the computer in order that we might save time.(2)so that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（in order） to get to school on time.(3)so that既可引导目的状语从句，又可引导结果状语从句。区别这两种从句的办法有两个：1)目的状语从句里往往带有情态动词can, could, may, might等。2)从意思上看，目的状语从句往往表示的目的很明确。例如： Speak clearly so that they may understand you. (目的状语从句) Jack is badly ill so that he has to rest. (结果状语从句)练习： I hurried I wouldnt be late for class. We should go by bus _ we can get there earlier. May I sit nearer I can see more clearly? (4) 补充：so as to(肯定结构) eg. He got up early so as to catch the early train. so as not to(否定结构) eg. He got up early so as not to miss the early train.to eg. He got up early to catch the early train. in order that eg. He got up early in order that he could catch the early train. in order to eg. He got up early in order to catch the early train.
