乐于助人80字的英语作文

On my way to school there was something wrong with my bike. What should I do? I would be late for class. I checked the bike again and again, but I didn't know what the matter was. I was so worried that I was wet all over. Just then an old man came up to me. "What's the matter, young man?" He said, "Let me help you." I was glad that my bike was mended a few minutes later.
I didn't really know what I should say. I thanked him again and again, He said with a smile, "It is my pleasure. We should help each other." Yes, we should help each other. When I see someone is in trouble, I will help him, too.
