When I was a little girl, my grandparents lived in a house with a big front yard. They loved each other and planted lots of vegetables and flowers together in the yard.

But one summer Grandpa died, so it was hard for Grandma to care for the garden alone. When spring came, she planted just a few vegetables and flowers.

One day in the early summer, Grandma heard big noises in the yard. She looked out of the window and saw thousands of bees.

What could she do? Should she hire someone to get rid of the bees? But that would cost more than she could afford. She decided to wait.

Over the next few days, the bees were busy with their own business. That summer, Grandma's little garden grew and grew. The neighbors would stop to admire the big crop of vegetables and the lovely flowers.

One day, Grandma's brother visited. When she told him about the bees, he said, "Farmers often hire beekeepers to come to their fields. The bees pollinate (授粉) the crops, which helps them to grow."

"So that's why my garden is doing so well!" She believed Grandpa had sent the bees to take his place and make Grandma's little garden grow and grow...
