Dear Frank,
I'm 1 at a middle school now. My school is nice and clean. There 2 thirty students in my class.
It's 3 today and it's hot. My classmates and I are playing on the beach. It's a nice place. The water is blue and clear. We are 4 a good time! There are 5 of birds flying over the sea. Many people are 6 in the sea. Some boys are 7 beach ball. Other people are 8 on the beach. One girl is 9 photos, I'm 10 that everyone can enjoy themselves in this heat.
Could you tell me something about your life? studying
