I help people on the bus.

I go to school by bus. There are many people on the bus. Some of them are old, some of them are smaller than me, and some of them are mothers with a baby. When I see them, I will let them sit on my seat. They will thank me. feel so happy, because I help people on the bus.
我乘公交车上学。车上有很多人。有些是老人，有些比我还小，有些是带着宝宝的妈妈。当我看到他们，我会给他们让座。他们会感谢我。我感到非常高兴，因为我在公交车上帮助了别人。
