你的作文存在几个问题：个别单词拼写错误,序数词排列问题,有些语句累赘,人称代指混乱,还有情态动词后的动词要用原形.按你的原意修改后的作文如下：
Nowadays,more and more children are living in a very nice condition.While their parents lived in a bad one in their childhood.So they can not learn how to be independent.
In order to help the children to be independent,I think their parents should do as follows:First,parents should let the children make decisions by themselves.Children should learn to depend on themselves to solve the problems which they may encount.Second,parents can make their children a hard situation,and encourage them to win.Last but not the least,parents need to communicate with their children frequently to know their ideas,and if the ideas are good,they should encourage them and give necessary help.
In my opinion,children is the future of our country,we should pay more attations on their growth,helping them to be independent.
