中文摘要：The feature describes how gardens provide fresh food, social connection and practical education. 训练重点：抓主题句、转折提示、因果链和 speaker attitude；复盘时标出至少 3 处同义替换。 核心词：community gardens；food access；neighborhood cooperation；urban land use

例句：Narrator: Listen to a campus news report. Reporter: A recent project on community gardens has attracted attention from students and local residents. Organizers say the project began with a narrow question about food access, but it soon revealed broader issues such as neighborhood cooperation and urban land use. During the first month, volunteers collected observations, interviewed users and compared results with earlier records. The most surprising finding was not that people supported the idea, but that many did not know how to participate. The team therefore created short guides and placed them near the relevant facilities. Experts say the project is still small, yet it offers a useful lesson: public action improves when information is specific, access is simple and feedback is visible. The next stage will examine community gardens in more detail.
