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.
