Dear Jack,
How time flies! I have been in high school for a whole month. At the beginning of this term, I felt a little lonely. But now I have made many new friends. By now, I have got used to my new life here. I miss all the teachers and classmates in Junior Middle school. At the same time, I get along well with my new classmates. The teachers here are very humorous and I like them very much. I will make good use of my time, because it is my dream to go to a good university after three years’ hard work.
Yours,
Tom
