Last weekend, I took part in a forest clean-up activity. It was organized by GreenHope,     1     an organization devoted to protecting forests. At first I didn’t want to take part in the forest clean-up activity, but then I thought. What if nobody goes?” our team leader, Joe, took us to a forest outside the city.     2     I was sad to see litter everywhere. There was a “No littering is allowed here” sign at the entrance to the forest,     3     but that didn’t stop people from throwing their rubbish on the ground. Joe divided us into two groups: one group cleaned up the north side of the forest, and the other group cleaned up the south. We worked for several hours and we were happy to see that the forest looked cleaner than it had looked before.     4     这绝对值得我们的努力. There’ll be another clean-up activity in the green belt next Saturday. You can find Joe and sign up if you’re willing to help.     5    每个参加该活动的人都将获得一枚奖章. I’ll join you too if I have time.
