    The sun is shining and the birds are singing. Spring is coming. It's very warm. The grass is green again. The air is getting fresh. We can see small beautiful flowers. We're planting trees on the outskirts(郊外),because there aren't trees here. Some boys are watering the trees. The small trees will become big trees. How happy we are!
