There was litter on the ground, and only a few small trees grew there. In summer, it was too hot to play because there was no shade. To fix this, the community asked everyone to join a “Green Park” activity. Every weekend, students, parents, and old people came to help. We picked up litter first—we filled 10 big bags with plastic bottles and paper. Then, we planted 50 young trees. Some experts told us how to water the trees and choose the right soil. It wasn’t easy. We had to dig holes with small shovels, and our hands got dirty. But no one gave up. After 6 months, the park changed a lot. The trees grew taller and made shade. Birds started to build nests in the trees. Now, kids play soccer there after school, and old people sit on benches to chat. This activity taught us that everyone can help improve the environment. Even small efforts can make a big difference to our living places. ( ) 1. What was the problem of the small park last year? A. It was too big to clean. B. It was messy with little trees. C. It had too many people. D. It was covered with water. ( ) 2. What activity did the community organize? A. A “Clean Street” activity. B. A “Green Park” activity. C. A “Save Water” activity. D.
