我们的神州大地
第一章：我们的神州大地
China: Our Divine Land
---
夜晚，仰望星空，你有没有想过，如果我们能像小鸟一样飞上天空，从很高很高的地方往下看，我们的中国会是什么样子呢？
Tonight, when you look up at the stars, have you ever wondered what China would look like if we could fly high up in the sky like little birds and look down at our country?
今天，我们要跟随一个小探险家，去完成一次神奇的中国之旅。我们会从太空出发，飞越960万平方公里的壮美山河，看看这片叫做“神州”的大地，为什么会有高高的山、深深的谷、宽阔的平原，还有奔腾的大河。
Today, we're going to follow a little explorer on a magical journey across China. We'll start from space, flying over 9.6 million square kilometers of magnificent mountains and rivers. We'll discover why this land called "Shenzhou" (meaning "Divine Land" in Chinese) has tall mountains, deep valleys, wide plains, and rushing rivers.
准备好了吗？系好安全带，我们出发！
Are you ready? Buckle up, here we go!

小探险家的神奇梦境
A Little Explorer's Magical Dream
有一个叫小山的男孩，他最喜欢做的事情就是趴在窗台上，看着远处的山发呆。有一天晚上，小山做了一个特别神奇的梦。
There was a boy named Xiao Shan, and his favorite thing to do was to lie by the window, gazing at the distant mountains. One night, Xiao Shan had a very special dream.
在梦里，小山发现自己坐在一朵软绵绵的白云上，白云越升越高，越升越高……
In his dream, Xiao Shan found himself sitting on a soft, fluffy white cloud. The cloud rose higher and higher...
“哇！”小山睁开眼睛，发现自己已经飞到了很高很高的天上。他低头一看——哇，那不是我们的中国吗！
"Wow!" Xiao Shan opened his eyes and found himself flying very, very high in the sky. He looked down and—wow—it was China!
从这么高的地方看下去，小山发现了一些很有意思的事情：他看到西部地区有很多很高很高的山，山顶上还盖着白色的“帽子”——那是终年不化的冰雪！往东走，山慢慢变矮了，平原越来越多。再往东看，他看到了一条长长的、闪闪发亮的带子——那是长江！最后，他看到了蓝色的大海。
From this high up, Xiao Shan noticed something interesting: in the western part, there were many very tall mountains with white "hats" on top—those were snow and ice that never melted! As he looked eastward, the mountains gradually got shorter, and there were more and more plains. Further east, he saw a long, sparkling ribbon—that was the Yangtze River! Finally, he saw the blue sea.
“好奇怪呀，”小山挠挠头，“为什么西边的山那么高，东边的山那么矮？为什么大江大河都是从西边往东边流呢？”
"How strange," Xiao Shan scratched his head, "why are the western mountains so tall and the eastern mountains so short? Why do all the big rivers flow from west to east?"
带着这些疑问，小探险家开始了他的探索之旅。而我们要告诉他的第一个秘密，就是关于中国地形的“三级阶梯”。
With these questions, the little explorer began his journey of discovery. And the first secret we're going to tell him is about China's "Three-Step Terrain."

从太空看中国：我们的家在哪儿？
Looking at China from Space: Where Is Our Home?
首先，让我们来认识一下我们的家——中国，在地球上的哪个位置。
First, let's get to know where our home—China—is located on Earth.
中国在哪里？
Where Is China Located?
如果把地球仪放在你面前，你会看到，在亚洲的东部、太平洋的西岸，有一个很大的国家——那就是中国！
If you put a globe in front of you, you'll see a very large country on the eastern side of Asia and the western coast of the Pacific Ocean—and that's China!
亚洲是世界上最大的洲，而中国就在亚洲的东部。我们国家的形状，像一只昂首挺胸的大公鸡。你看，它面向东方，好像在每天迎接太阳升起的方向呢！
Asia is the largest continent in the world, and China is located in the eastern part of Asia. The shape of our country looks like a proud rooster standing tall with its chest out. Look carefully—it's facing east, as if greeting the rising sun every day!
China is located in the eastern part of Asia, on the western shore of the Pacific Ocean. Let's remember this sentence in English: "China is in East Asia, on the western coast of the Pacific Ocean."
中国位于亚洲东部，太平洋西岸。 让我们用英文记住这句话：*"China is in East Asia, on the western coast of the Pacific Ocean."*
中国有多大？
How Big Is China?
小朋友们，你们知道中国有多大吗？
Do you know how big China is?
960万平方公里——这是我们的国土面积！这意味着，如果你每天走50公里，走完整个中国需要整整530年！
9.6 million square kilometers—this is our country's land area! This means if you walked 50 kilometers every day, it would take you 530 full years to walk across all of China!
在中国，我们常用“960万平方公里”来表示国土面积。但在世界上，这个数字代表什么呢？
In China, we often use "9.6 million square kilometers" to represent our land area. But what does this number mean in the world?
中国是世界上面积第三大的国家！排在第一位的是俄罗斯（1710万平方公里），第二位是加拿大（998万平方公里），第三位就是中国（960万平方公里），第四位是美国。
China is the third largest country in the world! The first is Russia (17.1 million square kilometers), the second is Canada (9.98 million square kilometers), the third is China (9.6 million square kilometers), and the fourth is the United States.
想象一下，中国的土地面积大约相当于100万个北京那么大！或者相当于1700万个足球场并排在一起！是不是大得惊人？
Imagine this: the land area of China is about the same as one million Beijing cities! Or 17 million football fields lined up side by side! Isn't that amazing?
我们的邻居
Our Neighbors
中国这么大，周围当然有很多邻居啦！
China is so big, of course it has many neighbors!
在北部和东北部，中国与俄罗斯和蒙古接壤；在西部，中国与哈萨克斯坦、吉尔吉斯斯坦、塔吉克斯坦、阿富汗、巴基斯坦和印度等国相邻；在南部，中国与尼泊尔、不丹、印度、缅甸、老挝和越南等国家接壤。在东方和东南方，中国隔着大海，与日本、韩国、菲律宾等国相望。
To the north and northeast, China borders Russia and Mongolia; to the west, China is adjacent to countries like Kazakhstan, Kyrgyzstan, Tajikistan, Afghanistan, Pakistan, and India; to the south, China borders Nepal, Bhutan, India, Myanmar, Laos, and Vietnam. To the east and southeast, China faces countries like Japan, South Korea, and the Philippines across the sea.
这么多邻居，大家你帮帮我，我帮帮你，就像一个大家庭一样！
With so many neighbors, everyone helps each other, just like one big family!
现在，小探险家已经知道中国在哪里、有多大了。接下来，我们要带他去看看中国最神奇的地形特点——三级阶梯！
Now the little explorer knows where China is and how big it is. Next, we're going to show him China's most amazing terrain feature—the Three-Step Terrain!

中国地形的秘密：三级阶梯
The Secret of China's Terrain: The Three-Step Terrain
在我们开始探索之前，先让我们用一张图来看看中国的三级阶梯是怎么分布的。
Before we begin exploring, let's look at a diagram to see how China's Three-Step Terrain is distributed.

从这张图上，你可以清楚地看到，中国的地形就像一个大大的台阶，从西到东，一级比一级低。这就是地理学家们说的“三级阶梯”！
From this diagram, you can clearly see that China's terrain is like a giant staircase, getting lower and lower from west to east. This is what geographers call the "Three-Step Terrain"!
第一级阶梯：世界屋脊
The First Step: Roof of the World
小探险家首先来到的地方，是中国的西部——青藏高原。
The first place the little explorer came to was western China—the Qinghai-Tibet Plateau.
青藏高原被人们称为“世界屋脊”，因为它是世界上最高的高原，平均海拔超过4000米！这是什么概念呢？如果你站在海拔4000米的地方，你会发现呼吸变得很困难，因为空气变得稀薄了。
The Qinghai-Tibet Plateau is called the "Roof of the World" because it's the highest plateau on Earth, with an average elevation exceeding 4,000 meters! What does this mean? If you stand at an elevation of 4,000 meters, you'll find it hard to breathe because the air becomes thin.
想象一下，如果把北京市的最高楼——中国尊（海拔约50米）搬到青藏高原上，你需要叠起80座中国尊那么高的楼，才能和青藏高原一样高！
Imagine if the tallest building in Beijing—China Zun (about 50 meters above sea level)—were moved to the Qinghai-Tibet Plateau. You would need to stack 80 buildings of that height just to match the plateau's elevation!
在青藏高原上，有世界上最高的山峰——珠穆朗玛峰，海拔8848.86米。珠穆朗玛峰的峰顶常年被冰雪覆盖，就像戴了一顶闪闪发亮的白色皇冠。
On the Qinghai-Tibet Plateau stands the world's highest mountain—Mount Everest, with an elevation of 8,848.86 meters. The summit of Mount Everest is covered with snow and ice year-round, like wearing a sparkling white crown.
青藏高原的南边，有一排排高大雄伟的山脉，叫做喜马拉雅山脉。喜马拉雅山脉就像一堵巨大的冰雪长城，阻挡着来自印度洋的暖湿气流。
To the south of the Qinghai-Tibet Plateau stands a row of tall and majestic mountains called the Himalayan Mountains. The Himalayas are like a giant wall of ice and snow, blocking warm and moist air currents from the Indian Ocean.
