1 You probably remember the Flaming Mountains from Journey to the West. But do you know where the real Flaming Mountains are They are in Turpan, in the east of the Xinjiang Uygur Autonomous Region.
地下生命之河
《西游记》中的火焰山
它们位于新疆维吾尔自治区东部的吐鲁番。
2 It's known as one of the hottest areas in the world. The desert sand can
be as hot as 80℃ in midsummer. That's enough to make your feet burn!
It may sound crazy, but the locals can cook an egg on the desert sand.
Rainfall in Turpan is only 16 mm a year. It is one of the driest places in
China. How do people survive in such a terrible climate The secret
lies in the ancient karez system.
它以世界上最炎热的地区之一而闻名。
足以灼伤你的双脚！
当地人能在沙漠的沙子上（沙窝里）烤鸡蛋
它是中国最干旱的地区之一。
人们如何在如此恶劣的气候中生存？
秘密就在于古老的坎儿井系统。
3 The karez system in Turpan includes more than 1,000 wells. They
appear every 20–30 metres. Some of them are 100 metres deep! Under
these wells are large underground canals. Water from the mountains falls
into the wells. It then runs underground in the canals. It is kept cool and
safe from the desert heat. There are over 5,000 km of underground
canals in the area. That's nearly as long as the Yellow River! Thanks to
the karez system, people can grow plants for food in this difficult
environment. And amazingly, all of this was completed with only hand
tools! No wonder it's among the top three projects of ancient China.
这些水得以保持凉爽，免受沙漠高温的影响。
难怪它被列为中国古代三大工程之一。
那几乎与黄河一样长！
在这艰苦的环境中种植作物以获取食物
仅凭手工工具完成的
4 Today, the area faces a water shortage. There is less water from
the mountains, lower rainfall and a large increase in water use.
Although modern technology is solving some problems, the
karez system still plays an important role. Now, more and more
young people are taking action to protect it. The centuries-old
water system will surely be carried into the future.
降雨量降低，而用水量却大幅增加
坎儿井系统仍然发挥着重要作用
采取行动保护它
这个有着数百年历史的水利系统必将延续至未来。

Learning to think
It's important to compare advantages and disadvantages of an ancient technology. In this way, we can make reasonable decisions about its usage in modern society.
Write a passage about
how people change nature.
Think of one example of people changing nature. Do research and find some interesting facts.
Step 1
Write your passage with the help of the chart.
Step 2
Opening
Introduce the topic.
What is the system / idea of changing nature
Where is it
When did it start
Body
Further explain the system / idea.
What are some amazing facts
How does the system / idea work
Ending
Share the importance of the system / idea and summarise your thought.
How important is it
Will people keep it in the future
Check.
Step 3
Did you:
clearly explain how the systems / idea works
use the words and expressions from the reading passage
give your opinion about changing nature
Share your passage with the class.
Step 4
One of the most famous examples of people changing nature is China's South-to-North Water Diversion Project (南水北调工程). This is a system that moves water from the rainy south to the dry north of China. The idea began in the 1950s, and
construction (施工) started in 2002.
How does it work There are three main routes (eastern, middle, and western) that use canals, tunnels (隧道), and pipelines (管道) to transfer water over long distances. An amazing fact is that the middle route alone is about 1,432 kilometers long – that's longer than the distance from Beijing to Shanghai! This system provides water for millions of people, helps farms grow crops, and supports factories in northern cities.
This project is extremely important because it solves serious water shortages in northern China. It shows how humans can use engineering to balance nature's resources. I believe people will continue such projects in the future to adapt to climate change. However, we must also protect rivers and use water wisely while changing nature.
