中文摘要：The lecture describes why wind and solar power need storage systems that can respond to changing demand. 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：renewable energy；battery storage；grid stability；peak demand

例句：Narrator: Listen to a campus news report. Reporter: A recent project on renewable energy has attracted attention from students and local residents. Organizers say the project began with a narrow question about battery storage, but it soon revealed broader issues such as grid stability and peak demand. 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 renewable energy in more detail.
