I am writing on behalf of Midfield School. Every year, our students choose to do a project on an environmental problem. Then, they work to raise money to help solve this problem. We have recently seen your advertisements about protecting dolphins, so for the last few weeks we have been trying to learn about the dolphins that live in the sea near our school. We have already been on two boat trips and have persuaded local fishermen to change their fishing nets because the ones they are using at the moment can trap dolphins. Could you please send the children some World Wildlife Fund posters to add to the presentations that they have done so far?

  I want to tell you how i spend my summer. I had been visit my lovely grandma in Moscow. Together we were in the zoo and in the dolphinarium. I enjoyed this so mush and it was so interesting. Later we visited the Pushkin Museum and the rest of the day we just walked in the park and enjoyed the weather. I was roller skating,
It was so fun!
  A bit later I went to visit my another grandma in the village.There I was riding with friends a bike, swimming in river and I also helped my grandmother in the garden. 
  My grandma has a beautiful cat, his name Cake and I really miss him. I think it was my best holidays.
