林尽水源，便得一山，山有小口，仿佛若有光。便合船，从口入。初极狭，才通人。复行数十步，豁然开朗。//土地平旷，屋舍伊然，有良田美池桑竹之属。阡陌交通，鸡犬相闻。其中往来种作，男女衣着，悉如外人。黄发垂髫，并怡然自乐。

——陶渊明《桃花源记》（节选）

    至于负者歌于途，行者休于树，前者呼，后者应，伛偻提携，往来而不绝者，滁人游也。临溪而渔，溪深而鱼肥，酿泉为酒，泉香而酒洌，山肴野蔌，杂然而前陈者，太守宴也。宴酣之乐，非丝非竹，射者中，弈者胜，觥筹交错，起坐而喧哗者，众宾欢也。苍颜白发，颓然乎其间者，太守醉也。

——欧阳修《醉翁亭记》（节选）

    There are many apple trees in a garden. They're good friends. One day an old tree is ill. There are many pests in the tree. Leaves of the tree turn yellow. The old tree feels very sad and unwell. Other trees send for a doctor for him. At first, they send for a pigeon, but she has no idea about it. Then they send for an oriole(黄鹂), and she can't treat the old tree well either. Then they send for a woodpecker. She is a good doctor. She pecks a hole in the tree and eats lots of pests. At last the old tree becomes better and better. Leaves turn green and green.
