Hello,tomorrow is Tree-planting Day. We are going to go for an outing this Sunday. In the morning, we are going to climb (爬) the hill. And we can plant some trees there. The boys are going to dig holes (坑, 洞). The girls are going to put trees in the holes and water them. We are going to have lunch after that on the hill. Then we are going to play games in the afternoon. I think we will have a good time.
