范文：
Dear dad mum , 
  I’ve already been here for a week . London is a beautiful city , but it rains a lot here . We have English classes every morning . In the afternoon , we sometimes play games , sometimes go out for sports . My classmates come from different parts of the world , so I have to talk in English . I like this school very much .
