为什么叫名词性从句?
_______________________
整个从句相当于一个名词
比较:
The man looked around.
That the boy failed again in the exam disappointed his mother.
同样作主语,从句可以表示较复杂的含义,一般是个动作或性质
I know him.
I know that he is writing position in his room
2. 为什么要有名词性从句?
那人看了看四周. (名词作主语)
那孩子考试又不及格令他母亲很失望. (从句作主语)
我知道他在房间里写作文.
从句的特征:
是一个句子,有一个引导词,引导词做从句的一个成分(that 除外)
名词能做的成分,从句都能做
从句表达的意思比名词复杂得多
主语从句
that whether who whom whose what which when where why how
从句
引导词:
1. That he knows Japanese is known to all.
他懂英语,这一点大家都知道
令我惊讶的是在这儿见到他.
3. When he e is unknown .
4. Whether he ing doesn’t matter much.
他来不来没什么要紧的
他什么时候来不清楚.
他们是怎么登上山顶的仍是个秘密.
5. It remains a secret how they climbed up the mountain.

That无词义,不可省略
What “什么”, “所….的”

1. It + be +形容词+ that 从句
2. It + be +名称词组(duty/pity..) + that 从句
3. It + be + 过去分词(said/thought..) + that 从句
4. It +不及物动词(seem/happen..) + that 从句
