Mr Smith and his son Jim rent a boat from Mr Green. They find a very good place and catch a lot of fish. Now it is late and they are going home.史密斯先生和他的儿子吉姆，从格林先生那里租了一条船。他们找到了一个非常好的地方并抓到了许多鱼。天色已经很晚了，他们要回家了。

　　Jim says, “I’ll come here again tomorrow.”吉姆说：“我明天还要再来这里。”

　　“Yes, me too.” say his father. “But how can we get back and find the right place again?” “I can make a mark on the side of the boat.” Jim answers.“是的，我也是。”他的父亲说。“但是我们怎么回来并找到正确的地方呢？”“我可以在船的一侧做个记号。”吉姆回答道

　　The father laughs and says, “No, that’s foolish! Mr Green won’t give us the same boat next time.”父亲大笑说道：“不那太愚蠢了!格林先生下次不会给我们同一条船的。”
