阅读下面短文，从A、B、C、D四个选项中选择最佳答案填空。
When I was young, my father used to take me on long walks in the countryside. These walks were not only fun but also educational. They taught me how to appreciate nature and enjoy the simple things in life. On one walk, we saw a beautiful butterfly. It was so colorful and graceful. My father told me that butterflies are important for the environment because they help plants reproduce. This made me realize how much we depend on each other in this world.
From then on, I started paying more attention to the little things around me. I noticed birds singing in the trees, flowers blooming in the fields, and streams flowing through the hills. I learned to respect all living creatures and understand their roles in the ecosystem.
These experiences have stayed with me throughout my life. They remind me to always look for beauty in the world and never take anything for granted.
