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.史密斯先生和他的兒子吉姆，從格林先生那里租了一條船。他們找到了一個非常好的地方并抓到了許多魚。天色已經很晚了，他們要回家了。

　　Jim says, “I’ll come here again tomorrow.”吉姆說：“我明天還要再來這里。”

　　“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。”他的父親說。“但是我們怎么回來并找到正確的地方呢？”“我可以在船的一側做個記號。”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.”父親大笑說道：“不那太愚蠢了!格林先生下次不會給我們同一條船的。”
