One day I rode bike to school as usual.Suddenly, there was something wrong with my bike.I tried my best to mend it,but I failed.I was very worried and didn't know what to do. Just then an old man came and helped me. A few minutes later, he mended the bike well.I was very glad and thankful, "Thank you very much."But the man waved his hand and went away.
一天，我像往常一样骑车去上学。突然车子出了毛病。我尽力修理 ，它，还是没修好。我急得不知该怎么好了。 这时一个老大爷走过来帮我，几分钟后车修好了。我又高兴，又感激，说：“谢谢您了。”他朝我挥了挥手走了。
