Ⅳ.短文改错
I was a sweet and loving girl during I was very young. Unfortunate, things changed. It all started when I was given smartphone in the eighth grade by a good friend. I became fond of watching movies, chat online and playing addictive games. Naturally, I couldn't make progresses in my study any more. What's worse, I spent fewer time in communicating with my parents. Thus, all of them were worried about what had been happened and turned to my head teacher for help. With their help, I realized what serious the things were and decided to change myself. Now I am grateful to them and became a good girl.
