Dear Tom,
I was surprising to receive your letter a few days ago. Since I came to the new school, I had planned to write to you. Therefore, the busy life of the school spared me no time. After came to the school, I made up of my mind to study hard. To tell you the truth, that was Miss White, my new English teacher, who changed my mind. She suggested that I give in my bad habits. Although he is very strict with us, all the students fond of her.
I have to stop here. I am looking forward to hear from you soon.
Yours,
