Dear Tom,

How are you? I'm at a new school this term. And I'm writing to tell you about my school. My new school is big and nice. There are one thousand and four hundred students and one hundred and forty teachers at my school. I like the teachers. They are very kind to me. My classmates are very friendly too. They teach me Chinese and l teach them English There are trees, flowers and green grass at my school. They are very beautiful. Behind my school there is a small river. The water in it is quite clean. We can swim in it. We have no classes on Saturdays or Sundays. Sometimes I play football or basketball with my classmates. Sometimes I stay at home and watch TV. Sometimes I go shopping with my father and mother. We all like China.

Please write to me soon!

Yours,

Jack
