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。
【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。
