One helper was a retired teacher who knew every bird by its call.有位帮手是退休教师，他能凭叫声认出每只鸟。 His knowledge of the wetland was phenomenal.他对这片湿地的了解「非凡」。 He said the quiet calls show how much biodiversity the place holds.他说，那些安静的叫声说明这地方有多少「生物多样性」。

Last spring the rain came late and was not sufficiently heavy.去年春天雨来得晚，下得也不「足够」大。 A researcher measured our precipitation.一位研究员测了我们的「降水量」。 He found it far below the usual level and checked the respiratory health of the fish.他发现雨水远低于平常水平，还检查了鱼的「呼吸的」健康。 He said a dry month can precipitate real trouble for a shallow lake.他说，一个干燥的月份能「促成」浅湖真正的麻烦。

Inevitably, every weekend gave me a new file to hear again.「不可避免地」，每个周末我都会得到一份新的录音，再听一遍。 That file now holds both the story of the wetland and each peripheral event.那个文件如今装着这片湿地的故事，也装着每一件「边缘的」小事。 The lake is protected, and at night the click of a fin means all is well.这片湖受保护了，夜里鱼「鳍」的轻响意味着一切都还好。
