帮你改了一点,如下.写得不错,加油啊
First, let me introduce myself. My name is jack, I'm 24 years old. I was born in shanghai. Shanghai is a very modern city. I love Shanghai, but the traffic there is terrible. Today, I will tell you a story, a story about myself. When I was five years old, I went to the kindergarten. I liked kindergarden very much because I could play there and it was a happy time. But happiness is always short. Then, I went to the elementary school. I didn’t like studying. It's too hard for me. It stole my playing time and freedom. I didn't know why I studied. When I was in the middle school, my English teacher always criticized me, and she always said: "Boy, knowledge is power. You don't dream away your time. you must study hard." I couldn't understand her at that time. But now I realize what she said is true. I feel so sorry to my English teacher. She was a woman about 40 years old then. She was very kind and I will never forget her. Last year, I made a big decision. I decided to carry my school bag and go to school again. I want to change my life, although my English foundation is nothing, but now, I will do my best to imporve it, and I want to improve my English ability. So I think I have to make an English study plan. First, I will read English articles, because I am not good at reading and often make mistakes when writing English. Then, I will try my best to learn more words by heart. And I will speak English as much as possible. I believe I can realize my dream through these learning plans. I want to make friends with all of the people here. At last,I want to say, this story is mostly written by myself. There must be many grammar mistakes in it. But I think, I should tell this story my way because the story is about myself.
