Every time it rained, a lake appeared outside the school gymnasium. It was not deep, but it was wide, and it smelled faintly of the drains. Students jumped it, slipped in it, and tracked it down the corridor. The caretaker, Mr. Duarte, put out a yellow cone that everyone ignored. Ana, who had joined the science club for the free biscuits, measured the puddle with a ruler and a piece of string. It was eleven metres long and came back after every storm, sometimes before the bell.
每次下雨，学校体育馆门外就会出现一个湖。它不深，却很宽，还隐约带着下水道的味道。学生们跳过它，滑倒在它里面，又把它一路带进走廊。管理员杜阿尔特先生摆出一个黄色警示锥，可谁也不理会。安娜加入科学社原本是为了免费饼干，她用一把尺子和一根绳子量了那摊积水：它有十一米长，每场暴雨后都会回来，有时下课铃还没响就先回来了。
She brought the numbers to the club. The asphalt, she explained, shed water like a roof; the drains were old and half blocked by leaves; the ground beneath had nowhere to drink. Her idea was a rain garden: a shallow hollow filled with soil and native plants that would catch the water and let it sink slowly. The club voted to try it. The principal agreed, on one condition: they had to raise the money, do the digging, and keep the entrance safe.
她把数据带到社团。她解释说，沥青像屋顶一样把水排走；下水道老旧，还被树叶堵了一半；下面的土地根本没有地方“喝水”。她的主意是建一座雨水花园：一个浅浅的洼地，填上泥土、种上本地植物，让水留在这里慢慢渗下去。社团投票决定试一试。校长同意了，但有一个条件：他们必须自己筹钱、自己挖土，并保证入口安全。
They raised money by washing bicycles and selling seedlings. Mr. Duarte donated three barrels and a wheelbarrow, then stood with his arms crossed while they dug. “Water goes where it wants,” he said. Their first attempt proved him right. They planted the hollow with flowers from a garden centre, and the first heavy rain filled it to the brim. The water sat for four days, the plants turned yellow, and Ben from the football team named it Lake Ana. Someone taped the name to a barrel.
他们靠洗自行车和卖树苗筹钱。杜阿尔特先生捐了三个木桶和一辆独轮车，然后抱着胳膊站在一旁看他们挖土。“水想去哪儿就去哪儿，”他说。第一次尝试证明他说得对。他们在洼地里种上从花卉市场买来的花，第一场大雨就把它灌得满满的。水积了四天，植物变黄了，足球队的本把它命名为“安娜湖”。还有人把这个名字贴在了一个木桶上。
Ana wanted to quit, but the club's rule was to test before giving up. They dug deeper, mixed sand and gravel into the clay, and chose plants that tolerated wet roots. Ben, who had mocked them, came back to help because his boots were the only ones tall enough. It took three weekends. On the last afternoon Mr. Duarte brought lemonade and, without being asked, built a low stone edge around the garden so nobody would step into it by accident.
安娜想放弃，但社团的规矩是：放弃之前先做测试。他们把坑挖得更深，在黏土里混入沙子和碎石，又换上了耐湿的植物。曾经嘲笑他们的本也回来帮忙，因为只有他的靴子够高。这项工作花了三个周末。最后一个下午，杜阿尔特先生端来柠檬水，还主动在花园四周砌了一圈矮石边，免得有人不小心踩进去。
The next storm arrived on a Tuesday. Ana watched from the library window as water ran off the roof, crossed the asphalt, and disappeared into the garden. By lunchtime the puddle was gone. She measured again: eleven metres had become a damp patch the size of a door. Mr. Duarte checked the drains, said nothing, and later put a small sign beside the garden that read “Please walk around. The ground is drinking.” Ben read it three times and laughed, this time without cruelty.
下一场暴雨在星期二到来。安娜从图书馆窗口望着水从屋顶流下，越过沥青路面，消失在花园里。到午饭时，积水不见了。她又量了一次：原来的十一米变成了一块门板大小的湿痕。杜阿尔特先生检查了下水道，什么也没说，后来却在花园旁立了一块小牌子，上面写着：“请绕行。土地正在喝水。”本读了三遍，笑了，这一次没有恶意。
The club presented their results at the spring fair: rainfall, water levels, plant survival, and the cost of one broken knee compared with one garden. They made no grand claims; they simply showed what had happened in their own yard. Two other schools wrote for the plans, and a council officer photographed the stone edge. Ana kept the taped barrel label in her notebook. Lake Ana had never been a lake, she thought. It had only been a place where nobody had asked the ground what it needed.
社团在春季集市上展示了结果：降雨量、水位、植物存活率，以及一块摔伤的膝盖和一座花园各自的代价。他们没有夸大其词，只是展示了自家院子里发生的事。另外两所学校来信索要设计图，一位市政工作人员还拍下了那圈石边。安娜把从木桶上揭下的标签夹进笔记本。她想，“安娜湖”从来就不是湖。它只是一个从没人问过土地需要什么的地方。
