It's not easy being your age,and it's normal to have these feelings.

问题描述:

It's not easy being your age,and it's normal to have these feelings.
我想问问大家这句话里前半句用being是不是表示一种状态表示处于.不可用to be,一般我们常说It's+形容词to do sth,it's 做形式主语,为什么前一句不可用to be 后一句中to have 可换为having吗?

being your age 作为句子的实际主语,it是形式主语
至于为什么不用更常用的不定式,因为不定式含有些微的将来和宽泛的含义
这里用动名词表示当下的状态更合适,而后面用不定式更好
