请用英语介绍一下你与三年前在外貌和性格方面的变化

I’m a middle school student.I've changed a lot in the plast three years.
Three years ago,I was short and thin.I used to be shy.My face used to turn red when i talked with others.In class,I used to be quiet and didn't ask and answer questions.
Now,I'm tall and strong.I'm more outgoing than I used to be .I 'm active in class and I can read text aloud before class.
I 've also made many friends.After class,I always communicate with my teachers and classmates.I think it is good to be a sunny girl.
