批判性思考题
核心隐喻统摄：filter 原义"过滤器/滤网"，如何统摄"图像调整→言语无修饰→信息筛选→消息渗透"四大义项？画出认知隐喻链条。
No filter 的文化脚本：speak with no filter 在英语文化中常被视为authenticity 表现，但在高语境文化（如中日韩）可能被视为rude。跨文化交际如何处理这一差异？
算法过滤 vs 人工过滤：含义 3 filter information 现多由算法自动完成（推荐系统、内容审核）。algorithmic filter, content moderation, filter bubble, echo chamber 等词汇如何改变了 filter 的语义内涵？
组织传播学视角：filter down/through 描述非正式信息流。grapevine, informal network, rumour mill, watercooler talk 等概念如何解释组织中信息的非正式传播？
数字时代 Filter 的双重性：Filter 既是用户工具（我选 formal shirts），也是平台控制手段（算法决定我看到什么）。user agency vs platform control 这一张力如何用英语讨论？(curate, personalize, manipulate, transparency)

Phil: Do you know what a ‘filter’ is? You probably know that a filter takes what you don’t want out of the thing that you do want, to make it cleaner – like a water filter. But did you know these meanings? It can be something you use to change a digital image.
Example: Get rid of that filter. It makes the pictures look ridiculous.
Phil: If someone speaks with no filter, they don’t worry what anyone else thinks.
