中考状语从句之原因、结果、目的状语从句：知识点+习题 ( 无答案）

原因、结果、目的状语从句

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b eca us e。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 t h at，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.

(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 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so…that, such…that, so that 引导。

2)so…that 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 couldn't 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 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 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 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 couldn't reach it.

【练习】

用so…that…或者such…that…填空：

1. It was hot in the cinema I felt very uncomfortable.

2. It was a funny film I laughed until I cried!

3. few people came to see the film the manager put on another film instead.

4.T om hurt his legs badly he was not able to walk for six months.
