【参考译文】

　　一天晚饭后，我去公园散步，碰巧在公园门口遇见了几位外宾。我走过去对他们说：“晚安”。他们微笑着并对我说：“晚上好”。

　　我非常吃惊，我不知道他们为什么不说“晚安”。所以我在回家后给我的老师打电话请求帮助。我的老师清楚的给我解释，当然是我说错了。

　　从这件事情我认识到，努力学习英语是非常重要的，学无止境

　　学无止境(there is no end to learning)

　　one day, i went out for a walk after supper. i happened to meet several foreign guests at the gate of the park. i went up to them and said, "good ning !" they smiled and said "good evening!" to me.

　　i was very surprised. i wondered why they didn't say "good night." so i called my teacher for help when i came back. my teacher explained it clearly and of course i was wrong.

　　from this event, i realize how important it is to study english hard. there is no end to learning.
