问题描述：
As children get older,they become more and more interested in everything.开头能不能换成
As their kids grow up,they become more and more interested in everything.
随着孩子的长大,他们对一切事物变的越来越有兴趣
答
不行.把their去掉就好了,变成：
As kids grow up,they become more and more interested in everything.
随着孩子的长大,他们对一切事物变的越来越有兴趣
这里kids是泛指,不能用定冠词,更不能用their.
