it is much good writing to him

问题描述:

it is much good writing to him
为什么用writing 而不用to write

writing动名词作逻辑主语,正常该说:writing to him is much good 给他写信有好处
更常用的是它的否定形式.it is no good doing sth 作某事没有好处不是也有it is good to do 的句型吗这两个是不同的。 我说的it is no good doing sth 作某事没有好处 “good”是名词,但是你说的it is good to do“good”是形容词,做某事是很友善的
