三、One Possible Version

Dear Peter,

   Our school photography club is going to hold an International High School Student Photography Show. The theme of the show is environmental protection. It will start from June 15th and last for three weeks. Any student who is interested is welcome to participate. I know you take good pictures and you’ve always wanted to do something for environmental protection. I remember you should me some photos on that theme the last time you visited our school. This is surely a good change for more people to see them. If you want to join, you can send your photos to intlphotoshow@gmschool.com.

   Hope to hear from you soon.

Yours,
