in order to make our city cleaner and more beautiful, the young volunteers of our school went to the people's park this morning and offered our help.
at eight, the head of the park met us at the gate. after being divided into groups, we set out to work at once. some tidied up the parking area and had motorbikes paiked in the right place. some took care of the flowers and bushes, and persuaded people to keep off the grass. around the tiger den, one group kept order to prevent accidents from happening. at the aquarium, another group worked as guides and advised visitors not to smoke. when some of us were doing cleaning, an old man praised us and said, "well done, young fellows!"
we were all tired but happy. what a morning we had today!
