原因结果目的状语从句讲解和练习(答案)(完美排版)

1、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 arent 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 fo

2、r 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 can buy it. t(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

3、yesterday _ there was something wrong with my bike.He took off his coat _ he felt hot.you can t answer the question, I ll ask someone else.二、结果状语从句(1)结果状语从句由sothat, suchthat, so 引that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 t

4、hat he couldnt say a word.Mother lives so far away that we hardly ever（几乎不，从来不）see her.在由 such that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

5、 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

6、so little time that he can t 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 couldn't 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 eno

7、ugh 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 wasa wonderful movieall of us wanted to see it again.There werelittle water in the bottlethe bird couldn t 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 c

8、atch 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

9、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 hurriedI wouldn't be late for class.We should go by bus _ we can get there earlier.May I sit nearerI can see more clearly?(4)
