However, she slowly accepted that she would spend the rest of her life with us in a little village far from her childhood farm.When the warm spring winds began to blow, Grandmother announced that she was going to plant a small garden.“I know,"she said when my father pointed out that we had no need to grow food. “We can buy all the food we need, but I have always grown a garden. And I insist that I’m going to plant one here,” replied Grandmother. She asked me if I would help her prepare the land for planting and I happily agreed.In early spring, she taught me how to plant vegetables. We put seeds of cabbages and tomatoes in small pots inside the house. I carefully watered them every day. Soon, little green sprouts(新芽) appeared.When the days were warm enough, we planted the seedlings（幼苗）into the small garden in the backyard. “In a month, we will have fresh vegetables to eat,” said Grandmother happily.When autumn arrived, we harvested the food. Grandmother made sure we always had something fresh on the supper table.Now that I'm older and living on my own, I still remember those wonderful meals with great fondness. I'm so glad to have spent those days looking after our plants in the summer heat.
