上一片里，小电脑用数据库把收藏整理得整整齐齐。可有一天，数据像洪水一样涌进来——这就是大数据。Last leaf, the little computer filed everything neatly into a database. Then one day data poured in like a flood — that is big data.
第 1 步：数据洪流从哪来Step 1: Where the flood comes from
先看看小电脑一天要吞下多少东西——来源比你想象的多得多。First see how much the little computer must swallow in a day — far more sources than you think.
你每刷一次手机，就吐出一串定位和点击；路上的传感器 24 小时数车流；每笔付款又添一条交易记录。三股洪流一起灌进小电脑，它张大嘴都接不住——这就是大数据的日常。Every phone swipe drops location and clicks; road sensors count traffic around the clock; each payment adds one more record. Three streams pour into the little computer faster than it can swallow — that is big data's daily life.
水多了就是大数据吗？还要看它“大”在哪 5 个方面。Is lots of water enough? It must be big in 5 ways.
第 2 步：5V，一个都不能少Step 2: The 5Vs, all five count
大量是堆成山，高速是来得快，多样是啥格式都有。这三 V 凑齐才算大数据；再加上价值（能挖出金子）和真实（不能是假水），5V 就齐了。Volume piles sky-high, Velocity rushes in, Variety mixes every format. Those three make big data; add Value (gold to dig out) and Veracity (no fake water) — all 5Vs complete.
这么多水有啥用？用好了，它就是“新石油”。What is all that water for? Refined well, it becomes the “new oil”.
第 3 步：数据是新石油Step 3: Data is the new oil
石油炼一下变成汽油，数据炼一下变成推荐：你看过什么，它就猜你喜欢什么。城市也一样，靠车流数据治堵——炼数据的，就是今天的炼油厂。Oil refines into fuel; data refines into recommendations: what you watched teaches it what you will love. Cities do the same, easing traffic with flow data — today's refineries refine data.
🎮 你来开闸放水（30 秒）🎮 Your turn: open the floodgate (30 seconds)
道理讲完了。先拖滑块给小电脑开数据源，看什么时候溢出成大数据；再闯 4 关，给场景和 5V 对号入座。Theory done. First drag the slider to open data sources and watch it overflow into big data; then clear 4 rounds matching scenes and 5Vs.
一句话记住它：大数据 = 又多、又快、又杂的数据；炼好了就是“新石油”，能推荐、能预测、能治堵。Remember it in one line: big data = huge, fast, mixed data; refined well it is the “new oil” — recommending, predicting, unclogging cities.
