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 his composition 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
