一、咪咪降落了——一个关于"很多很多人"的问题 / Mimi Has Landed — A Question About "Lots and Lots of People"

飞机穿过厚厚的云层，窗外突然亮了起来。

The plane broke through thick clouds, and suddenly the window lit up.

Mimi（咪咪）是一个喜欢问"为什么"的小女孩，今年八岁半。她住在加拿大一个叫 Sudbury（萨德伯里）的小城，那里森林很多，雪也很多，整个城市的人口还不到 17 万。今天是她第一次坐国际航班，第一次来亚洲。她跟着妈妈从温哥华起飞，飞了将近十个小时，中间在飞机上睡了两觉，看了三集动画片，吃了一盒有点咸的飞机餐。

Mimi (咪咪) is a little girl who loves asking "why." She is eight and a half years old. She lives in a small city called Sudbury, in Canada, where there are many forests and lots of snow. The whole city has fewer than 170,000 people. Today is her first time on an international flight, her first time coming to Asia. She flew with her mom from Vancouver for nearly ten hours. She slept twice on the plane, watched three cartoon episodes, and ate a slightly salty airplane meal.

飞机开始下降的时候，妈妈轻轻推了推她："Mimi，醒醒，我们要到了。"

When the plane began to descend, Mom gently nudged her: "Mimi, wake up. We're almost there."

她揉了揉眼睛，把脸贴在飞机的小窗户上。

She rubbed her eyes and pressed her face against the small window.

然后她"哇"了一声。

Then she said, "Wow."

窗外的灯光像撒在黑色天鹅绒上的碎钻石。一片一片，又一片一片，再一片一片，连成一片光的海洋，一直铺到天边。她从来没见过这么多灯。在 Sudbury 的夜晚，她抬头看星星，能数出几百颗。但是在这里，星星反而显得很少，因为地上的灯实在太多了。

The lights outside were like diamond chips scattered on black velvet. One patch, then another, then another, all connected into an ocean of light, stretching all the way to the horizon. She had never seen so many lights. In Sudbury at night, she could look up and count hundreds of stars. But here, the stars looked few — because there were just so many lights on the ground.

"Mimi，你看，这就是东京。"妈妈说。

"Mimi, look. This is Tokyo," Mom said.

"东京？"Mimi 重复着这个名字。她在飞机上的小电视里看过一点介绍，知道日本是一个岛国，知道东京是日本的首都。但是"首都"两个字，对一个八岁半的孩子来说，还是太抽象了。她看着那片光的海洋，心里冒出了三个问题：

"Tokyo?" Mimi repeated the name. She had watched a little introduction on the plane TV — she knew Japan was an island country, knew Tokyo was its capital. But the word "capital" was still too abstract for an eight-and-a-half-year-old. Looking at that ocean of light, three questions rose in her heart:

> 问题一：这么多灯，是给谁开的？ > Question 1: Who are all these lights for? > > 问题二：这里到底有多少人？ > Question 2: How many people actually live here? > > 问题三：他们每天怎么出门、上学、上班呢？ > Question 3: How do they go out, go to school, go to work every day?

这三个问题看起来很简单。但 Mimi 不知道，这三个问题每一个都能讲出一整本书。今天，我们就跟着 Mimi 一起，先来回答第二个问题：东京到底有多少人？

These three questions seem simple. But Mimi didn't know — each of them could fill a whole book. Today, let's follow Mimi and start with the second question: How many people actually live in Tokyo?

💡 小提示 / Little Hint：在继续读下去之前，你可以先猜一猜——东京的人口，是 Sudbury 的 10 倍？100 倍？还是更多呢？ 💡 Little Hint: Before you keep reading, take a guess — is Tokyo's population 10 times Sudbury's? 100 times? Or even more?

二、什么是"超级大城市"？/ What Is a "Megacity"?

飞机降落在成田机场。海关、行李、转弯、地铁。Mimi 跟着妈妈走了很久很久，等到终于坐上一辆开往市区的小火车时，她已经累得靠在妈妈肩膀上了。

The plane landed at Narita Airport. Customs, luggage, turns, subway. Mimi followed her mom for a long, long time. By the time they finally got on a small train heading to the city, she was tired and leaning against Mom's shoulder.

"妈妈，"她问，"东京有多少人呀？"

"Mom," she asked, "how many people live in Tokyo?"

妈妈笑了笑，说了一个数字："三千七百万左右。"

Mom smiled and said a number: "Around thirty-seven million."

Mimi 张大了嘴巴。她在 Sudbury 的同学只有 23 个人，整个学校加起来也就 400 多人。三千七百万是多少个 400？她在脑子里算了一下，怎么也算不清。

Mimi opened her mouth wide. Her class in Sudbury had only 23 kids, and the whole school added up to about 400 people. How many 400s are there in thirty-seven million? She tried to calculate in her head, but couldn't figure it out.

"妈妈，三千七百万是几个零？"

"Mom, how many zeros are in thirty-seven million?"

"七个零。三千万是 30,000,000，三千七百万是 37,000,000。"

"Seven zeros. Thirty million is 30,000,000, and thirty-seven million is 37,000,000."

"那比我们学校多好多好多倍……"

"That's many, many times more than our school..."

"是很多很多倍，"妈妈说，"但是东京不只是一个普通的'很大的城市'，它有一个特别的名字。"

"Many, many times more," Mom said. "But Tokyo is not just a regular 'very big city.' It has a special name."

"什么名字？"

"What name?"

"超级大城市，英文叫 megacity。"

"Megacity. In English: megacity."

2.1 "Mega" 是什么意思？/ What Does "Mega" Mean?

小朋友，你有没有在电视上听过这些词？MP3，megabyte（兆字节），megaphone（扩音器）。这些词都有一个共同的开头：mega。

Hey kid, have you heard these words on TV? MP3, megabyte, megaphone. They all share a common beginning: mega.

Mega 是一个来自古希腊语的词，意思是"巨大"。科学家和工程师很喜欢这个词——他们用 mega 来表示"很大很大的数量"。

Mega is a word from ancient Greek, meaning "huge." Scientists and engineers love this word — they use mega to mean "a really, really big amount."

**1 megabyte** = 一百万个字节 = a million bytes
**1 megaton** = 一百万吨 = a million tons
**1 megacity** = 一千万以上人口的城市 = a city with more than 10 million people

所以 megacity 不是"任何一个大城市"——它是一个特别的词，专门用来形容那些特别特别大的城市。普通的"大城市"可能只有二三百万人口，而 megacity 至少要有一千万人（10 million）。

So megacity doesn't mean "any big city" — it's a special word, used only for cities that are really, really big. A regular "big city" might have only two or three million people, while a megacity must have at least ten million.

> 💬 小知识 / Fun Fact： > 在 1950 年的时候，全世界只有两个 megacity：纽约和东京。到了 2024 年，全世界已经有三十多个 megacity，其中大部分在亚洲。 > In 1950, there were only two megacities in the whole world: New York and Tokyo. By 2024, there are more than thirty megacities worldwide, and most of them are in Asia.

2.2 世界上有哪些 megacity？/ What Megacities Are There in the World?

让我们来认识一下世界上最大的几个 megacity：

Let's meet some of the largest megacities in the world:

🇯🇵 **东京 (Tokyo)**：约 3,700 万人 / About 37 million
🇮🇳 **德里 (Delhi)**：约 3,200 万人 / About 32 million
🇨🇳 **上海 (Shanghai)**：约 2,900 万人 / About 29 million
🇧🇷 **圣保罗 (São Paulo)**：约 2,200 万人 / About 22 million
🇲🇽 **墨西哥城 (Mexico City)**：约 2,200 万人 / About 22 million
🇪🇬 **开罗 (Cairo)**：约 2,200 万人 / About 22 million
🇧🇩 **达卡 (Dhaka)**：约 2,200 万人 / About 22 million
🇮🇳 **孟买 (Mumbai)**：约 2,100 万人 / About 21 million

你可以看到，东京依然稳稳地坐在第一名。它的"东京大都市圈"（Greater Tokyo Area）包括东京市本身和周围的几个县，住着大约 3700 万人。

You can see that Tokyo still sits firmly in first place. Its "Greater Tokyo Area" includes Tokyo city itself and several surrounding prefectures, with about 37 million residents.

📊 数字比较 / Number Comparison

> 3700 万 = 37,000,000 > 澳大利亚（Australia）总人口 ≈ 2,600 万 > 加拿大（Canada）总人口 ≈ 4,000 万 > > 也就是说，东京都市圈的人口，比整个澳大利亚的国家人口还多，几乎和加拿大一个国家差不多！ > > In other words, the population of Greater Tokyo is more than the entire country population of Australia, and almost as much as the whole country of Canada!

Mimi 听完，下巴都快掉了："妈妈，一个城市里住的人，比一个国家还多？"

When Mimi heard this, her jaw almost dropped: "Mom, one city has more people than a whole country?"

"是的。所以它才叫 megacity 呀。"妈妈笑着说。

"Yes. That's why it's called a megacity," Mom said with a smile.

三、东京在哪里？它在地图上是什么样？/ Where Is Tokyo? What Does It Look Like on the Map?

在继续讲下去之前，让我们先用一张图来看看东京在世界的什么地方。

Before we continue, let's use a picture to see where Tokyo is in the world.
