1.1　一个还没有机器的世界

1.1　A World Without Machines

> 核心问题 / Core Question：工业革命之前，人们是怎样度过一天的？所有的"力气"从哪里来？

Imagine a world with no cars, no electric lights, no running water, no phones. 在很久很久以前——大约 270 多年前，也就是公元 1750 年前后——世界就是这个样子。

故事要从一个清晨开始。在英格兰中部一座小山脚下的小村庄里，住着一个叫莉莉（Lily）的八岁女孩。村子的名字叫"灰柳村"（Grey Willow），村边有一条小河，河上有一座石头小桥，桥那边是磨坊主托马斯的家。Lily 不知道，她的这一天，将和未来几百万个孩子的"世界"非常不一样。

It's the year 1750. Deep in the middle of England, a small village sits at the foot of a green hill. An eight-year-old girl named Lily lives there with her mother, her father, and her little brother Tom. The village is called Grey Willow. A little stone bridge crosses a slow river, and on the other side lives Thomas the miller. Lily does not know it yet, but her day will be very different from yours.

天还没有亮。莉莉睁开眼睛，看见窗外的天空是一种灰蓝色，星星还剩几颗，月亮快要落下去了。房间里很冷，因为她身下的床单是亚麻布的，妈妈前天才洗过，凉凉的。她没有毛绒玩具，也没有暖气的"嗡"声——她只有一张稻草填充的床垫、一条羊毛毯子，还有一只小猫蜷在她的脚边。

It is still dark. Lily opens her eyes. The sky outside is a quiet blue-grey. A few stars remain, and the moon is about to set. Her room is cold, because the linen sheet her mother washed two days ago is cool against her skin. There is no radiator humming, no night-light glowing, no soft toy to hug. There is only a straw mattress, a wool blanket, and a small cat curled up at her feet.

这就是我们要回答的第一个问题：在那个还没有电、还没有汽油、还没有蒸汽机的世界里，"起床"之后要做哪些事情？ 这些事情看上去很简单：打水、生火、烤面包、挤牛奶。可是，每一件都和"力气"有关——人的力气、牲畜的力气、风的力气、水的力气。整个世界，就是靠这四种力气在转动。

Here is the first big question of our story: *In a world with no electricity, no petrol, and no steam engine, what did people do after they woke up?* The list sounds simple: draw water, light a fire, bake bread, milk the cow. But every single task is about one thing—power. The power of human muscles. The power of animals. The power of wind. The power of water. The whole world, in 1750, runs on these four kinds of power.

> 🔑 关键词 / Key Words > > - 工业革命 / the Industrial Revolution：从 18 世纪中后期开始，人类开始用蒸汽、煤炭和机器代替人力和畜力的巨大变化。/ A great change starting in the mid-1700s, when people began to use steam, coal, and machines instead of only muscles and animals. > - 动力 / power：在物理上，让物体动起来或者让事情发生所需要的"力气"。/ In physics, the energy that makes things move or happen.

让我们用一个数字来记住这个时代：

Let's remember this moment in history with one big number:

$$ 1750 \;\text{年} \;\longrightarrow\; \text{四种"老动力"：人、牲口、风、水} $$

$$ 1750 \;\longrightarrow\; \text{Four "old powers": people, animals, wind, water} $$

250 多年以后，今天的小朋友只需要按一个按钮，就能打开灯、烧开水、洗衣服。从"按按钮"到"按按钮"，中间发生了什么？这一切的起点，就是莉莉的这个清晨。

More than 250 years later, you only need to press a button to turn on a light, boil water, or wash clothes. What happened in between? The whole story begins right here, on Lily's quiet morning.

1.2　莉莉的清晨：让一个家醒过来

1.2　Lily's Morning: Waking Up a Whole House

1.2.1　第一件工作——打水

1.2.1　First Task — Drawing Water

天刚刚亮，莉莉就穿好衣服，跟着妈妈出门。她们要去打水。Lily 家的后面有一口老井，井口是青石砌成的，井沿长满了青苔。井里装着一根长长的绳子，绳子下面挂着一个木桶。

As soon as the sky turns a little lighter, Lily gets dressed and follows her mother outside. Behind their cottage is an old stone well. Its rim is covered in soft green moss. A long rope hangs down into the well, and at the end of the rope is a wooden bucket.

妈妈说："莉莉，先打三桶水洗碗，再打两桶水煮粥，最后打两桶水给奶牛喝。今天一共是七桶。"

Mother says, "Lily, first three buckets for washing dishes, then two for the porridge, then two for Daisy the cow. Seven buckets in total."

我们帮莉莉算一算：

Let's do Lily's math with her:

• 每一桶水大约 10 升（大约 10 千克重）。
• 七桶就是 70 升，大约 70 千克。
• 一个八岁女孩的体重大约 25 千克。
• **她每天要提的水，比她自己还要重将近 3 倍。**

• Each bucket holds about 10 litres, which weighs about 10 kilograms.
• Seven buckets = 70 litres = about 70 kilograms.
• An eight-year-old girl weighs about 25 kilograms.
• **The water Lily lifts every day is nearly three times her own body weight.**

这就是"人力"的真实模样：辛苦、缓慢，而且每个人都不一样——力气大的人能多提一些，力气小的人就只能提几桶。没有任何机器会来帮莉莉，她必须一次又一次地弯下腰、抓住绳子、往上拉。

This is what "human power" really looks like: hard, slow, and unequal. Strong people can lift more; small people can lift less. No machine comes to help Lily. She must bend, grip, and pull—again, and again, and again.

> 🤔 思考一下 / Think About It > 今天我们刷牙、洗脸、喝水、冲厕所、做饭……每一个动作背后，都有"水"在工作。请你和爸爸妈妈一起算一算：你们家一天要用掉多少升水？这些水是怎么"自动"流到家里来的？

> Today, every time you brush your teeth, wash your face, drink water, flush a toilet, or cook, water is working for you. Try this with your parents: how many litres does your family use in one day? How does all that water reach your house "by itself"?

1.2.2　第二件工作——生火

1.2.2　Second Task — Making Fire

水打回来了，下一步是生火。Lily 的家里没有"打火机"（那时候还没有这种东西），也没有"煤气灶"。她要做的，是用火石（flint）和火绒（tinder）打出火星。

Now the water is in. The next step is to make a fire. There is no lighter (they have not been invented yet) and no gas stove. Lily must use flint and tinder to create a spark.

``` 打火的小步骤 / Steps to Make a Spark:

1. 准备一小撮干燥的火绒（可以是干草、树皮、棉絮）。 Prepare a small pinch of dry tinder (dry grass, bark, or cotton).

2. 用钢片（钢铁做的刀子）用力敲击火石。 Strike a piece of steel (a knife) hard against the flint stone.

3. 火星溅到火绒上，轻轻吹气，让火星变成小火苗。 Sparks fall onto the tinder; gently blow until the spark becomes a small flame.

4. 把火苗放进灶膛，慢慢加上小木棍，再加大木柴。 Place the flame in the fireplace; add small sticks, then bigger wood. ```

听起来很浪漫，对不对？可是，在寒冷的清晨，莉莉的手指冻得通红，她要花大约 5 到 10 分钟才能让火苗稳定下来。在这 5 到 10 分钟里，她什么饭都做不了，什么水都烧不开。

Sounds romantic, right? But on a cold morning, Lily's fingers are red and stiff. It takes her about 5 to 10 minutes to get a steady flame. During those 5–10 minutes, she cannot cook anything, and she cannot boil any water.

> 💡 小知识 / Fun Fact > 中国人在 6 世纪就发明了火柴的"祖先"——一种涂了硫磺的小木棒。但是真正能"一擦就着"的安全火柴，要到 1855 年才被发明。也就是说，莉莉生活的年代，距离"一擦就着"还有 100 多年。

> The Chinese invented an early ancestor of the match in the 6th century—a small stick coated in sulphur. But the safe match you can strike in one easy move was not invented until 1855. So in Lily's time, people still had another 100 years to wait.

1.2.3　第三件工作——烤面包和挤牛奶

1.2.3　Third Task — Baking Bread and Milking the Cow

火生起来以后，妈妈开始揉面做面包。面粉是上周爸爸去镇上的磨坊磨的，麦子是去年夏天自家田里收的。妈妈要做的是全麦黑面包——颜色深、味道粗、但很顶饱。

Once the fire is going, Mother begins to knead dough. The flour was ground last week by Father at the town's mill. The wheat was harvested from their own field last summer. Mother is making a wholemeal brown loaf—dark in colour, rough in taste, and very filling.

烤面包需要大约 45 分钟。在这 45 分钟里，莉莉不能闲着，她要去挤牛奶。

Baking takes about 45 minutes. Lily cannot sit still; she must go milk the cow.

莉莉家有两只奶牛，一只叫 Daisy，另一只叫 Petal。Lily 每天早上要分别挤它们。她坐在一只小木凳上，把木桶放在奶牛的肚子下面，双手一前一后地挤，牛奶"嗒嗒嗒"地流进桶里。一头奶牛要挤大约 5 分钟，两头就是 10 分钟。Lily 每天能从两只奶牛身上挤出大约 6 到 8 升牛奶——这些牛奶是全家人一整天的食物来源：早餐喝粥加奶，午餐煮汤加奶，晚餐做奶酪。

Lily's family has two cows: Daisy and Petal. Every morning she milks them one by one. She sits on a small wooden stool, places the bucket under the cow, and presses her hands in a steady rhythm: *squeeze, release, squeeze, release*. Each cow takes about 5 minutes, so 10 minutes in total. From the two cows she gets about 6 to 8 litres of milk a day. This milk is the family's food for the whole day: in the morning porridge, in the midday soup, and in the evening cheese.

让我们用一张流程图，把 Lily 一个清晨的"动力循环"画出来。

Let's draw a flowchart to show Lily's morning "power cycle."

```mermaid flowchart TD A[Sunrise 太阳升起] --> B[Draw Water 用人力打水] B --> C[Strike Flint 用火石生火] C --> D[Bake Bread 烤面包] D --> E[Milk the Cows 用人力挤牛奶] E --> F[Feed the Chickens 喂鸡] F --> G[Wash and Eat 洗漱吃饭] G --> H[Work Begins 开始劳作] H --> I[Sunset 太阳落山] I --> J[Oil Lamp 油灯] J --> K[Sleep 睡觉] K --> A ```

这张图就是一个"动力循环"——所有的箭头，都连着 Lily 的手、她的脚、或者她的家人。我们用眼睛跟着箭头走一遍，就会发现：今天做早餐需要 6 种不同的力气，全部来自人和牲畜。 没有任何一样，是从"插座"里来的。

**This flowchart is a "power cycle." Every arrow connects to Lily's hands, her feet, or her family. Follow the arrows with your eyes, and you will see: making breakfast uses six different kinds of effort, and all of them
