新概念英语三56课第2段
We have special river birthday parties in the summer. Sometimes were go upstream to a favourite backwater， sometimes we have our party at the boathouse， which a predecessor of ours at the farm built in the meadow hard by the deepest pool for swimming and diving. In a heat wave we choose a midnight birthday party and that is the most exciting of all. We welcome the seasons by the riverside， crowning the youngest girl with flowers in the spring， holding a summer festival on Midsummer Eve， giving thanks for the harvest in the autumn， and throwing a holy wreath into the current in the winter.
