难忘的一件事的英语作文

I still remember the first day I went to the zoo. When I was only five years old, my mother took me there. I was pleased to see so many real animals at the same time. They seemed so lovely and active. I spent a nice day. But on my way home, I began to feel sorry for them. They were taken away from their parents and friends and also far away from the nature. They must have felt lonely, I thought. Every day, the only thing they could do was to sit there and wait for food.
