I'm a Big Girl 我是一名懂事的女孩了

Now I will be in middle school soon, then I realize that I need to grow up. Usually, when I meet troubles, I will ask my parents for help in the first time. But now, I want to solve them by myself. I should try to be independent. I am so happy that I have made big progress. I am a big girl. 
我现在准备上中学，我知道到我需要成长了。通常，当我遇到问题时，我会第一时间向我的父母求助，但是现在，我想自己解决这些问题。我应该尝试独立。我很高兴我有了很大的进步。我是个懂事的女孩了。
