中文摘要：The speaker analyzes how fashion firms and consumers can reduce waste without ignoring affordability. 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：fast fashion；supply chains；textile waste；consumer choice

例句：Narrator: Listen to part of a lecture in a university course. Professor: Today I want to focus on fast fashion. Many people notice the visible problem, but they often miss the system behind it. The first point is supply chains, which helps shape what individuals can actually do. A second factor is textile waste; without it, even well-designed plans may fail. Let me give you a simple example. When a campus changes only one rule, students may react for a week. When the rule is connected with feedback, facilities and clear responsibility, the change becomes easier to maintain. This is why researchers now pay attention to consumer choice, not just personal motivation. The practical conclusion is modest: policy should make the desirable action convenient, measurable and socially normal. If you remember one thing from this lecture, remember that this issue is not an isolated detail but part of a larger pattern.
