Dear mom, I'm very happy to tell you that I'm going to join the Y & Y Green Group of my school. The Green Group is holding an environment month. We are going to clean the banks of the lakes on weekends. We are going to plant trees and flowers in the school garden and water them every afternoon after class. We are planting young trees and plants to sell to other schools. We hope that we can give more green color to the city and earn some money for our school Y&Y. The program is very interesting and useful, isn't it ? I will tell you more about the group activities later. Love, Hoa Choose True or false. Hoa is going to join the Y & Y Green Group of her school.
