W riting 6 Leggi la e-mail che hai ricevuto dal tuo amico Colin a proposito di una campagna ecologista. Rispondigli usando 80-100 parole. Hi! How s life? Everything s OK here. I m writing to ask you for some advice. Some of my classmates would like to join the Clea n Up the World campaign next year, obviously involving all of our class. As you have already had experience of this kind of activity, can you suggest anyth ing we could do? We were thinking of organizing a Gree n Club , a sort of environmental group: would it be a good idea? What about starting a recycling programm e at school? Tell me about the experience you had. I can t wait for your reply and your tips. Bye! Colin 69
