文化馆收集三代人的聊天。为什么同一个意思会换说法？The fair records three generations. Why do expressions change?
第 1 步：词语随生活变化Step 1: Words follow life
先从新事物的名字找线索。Start with names for new things.
技术和交往会带来新词。借词是从其他语言吸收词语。旧词也可能获得新义。变化并不自动等于语言退步。Technology and contact can introduce new words. Borrowing adopts words from another language. Older words can gain meanings. Change does not automatically mean decline.
第 2 步：变化不只在词汇Step 2: More than vocabulary
除了新词，声音与结构也会变。Sounds and structures can change too.
不同年代的发音和语法会变化。历史语言学比较规律对应。两个词碰巧相似，不能单独证明语言有亲缘。Pronunciation and grammar change across time. Historical linguistics compares systematic correspondences. Two similar-looking words alone do not establish a family relationship.
第 3 步：保存材料再比较Step 3: Compare documented evidence
怎样避免凭印象讲历史？How can we avoid relying on impressions?
文化馆给录音标明年代和地点。书面材料与口语记录相互补充。资料缺失处要保留不确定性。保护语言也包括尊重说话者。The fair labels recordings by time and place. Written records and speech recordings complement each other. Gaps require uncertainty. Language preservation also involves respecting speakers.
🎮 你来探索与判断🎮 Explore and reason
先操作实践台，再用四个挑战检验理解。每次判断都能看见理由。Explore the practice table, then try four challenges. Each judgment comes with a reason.
一句话记住它：语言会变化，解释变化需要历史证据。Remember: Languages change; explaining change requires historical evidence.
新词、词义、发音都可能改变。Words, meanings and sounds can change.相似不等于亲缘已被证明。Similarity alone does not prove relatedness.记录年代、地点和说话者。Record time, place and speakers.
来源与理解边界Sources and limits
语言变化是共识；具体亲缘和年代需专门比较。不要给语言排高低。Language change is established; particular relationships and dates need specialized evidence. Avoid ranking languages as superior or inferior.
