Dear Sam,
Thanks very much for your email. It was good (1) hear from you again.
So, you want to know about my school. Well, it has more (2) 1000 students and the buildings (3) very large. I got lost a few times at the beginning of the term!
The students (4) my class are very friendly and most (5) the teachers are not too strict.
(6) are many clubs to go to after school, so I joined the volleyball and the art club.
See you soon,
Bob
