One day in autumn, a mother duck took her children for a walk. The ducklings were very happy. In this way, Mother Duck led her out of the house and came to Vancouver Street.

Vancouver Street is really lively. Ducks look around one by one, and they are about to cross the road. Mother duck waddled along with her children. Because the excitement of the ducklings hasn't stopped, on the way, several ducklings slipped and fell into the sewer in the middle of the road, only to hear a "plop". When the mother duck heard the sound, she quickly turned around and heard several "quacks" coming from the sewer. She ran to the sewer and looked down, only to see a few ducklings struggling desperately in the water. Mother Duck was in a hurry and suddenly found a group of patrolmen. They came running on a swing, flapping their wings while screaming and biting the pants of the captain who led the patrol. The captain felt very strange, so he followed the mother duck to the sewer and found several ducklings flapping in the water. I understood at once, and quickly went to find a fishing net to catch fish and send the duckling safely to my mother. Mother duck was very grateful, called twice to express her thanks, and took the ducklings on the road again.
