Planting trees

Planting trees is a great way to make the air fresher and make our city greener. If you're over 12 years old, come and help us to plant more trees in South Lake Park. Let's meet at the north gate of the park at 8:30 a.m. this Saturday. You'd better wear sports shoes.

Repainting walls

The buildings covered with graffiti（涂鸦）are terrible. "This Sunday, we are going to repaint the walls of Xinhua Street and make them clean again. Anyone who is over fourteen can join us. Please arrive at No. 16, Xinhua Street at 9：30 a. m. You needn't bring any tools. Just remember to wear old clothes！

Collecting rubbish

You can hang out with your friends in the park and clean up our city parks at the same time! We are going to collect rubbish at Times Square from 8:30 a. m. to 10: 30 a. m. next Saturday. No matter how old you are, come and join us! Anyone who collects the most rubbish can get a gift for fun.
