Our planet has many amazing places, and one of them is Vinicunca in Peru. Known as the Rainbow Mountain,
it is famous for its bright lines of red, yellow, green and purple. It is part of the Andes Mountains (安第斯山脉), the
longest mountain chain (山脉) on earth. At 5,200 metres tall, it is even taller than other famous mountains. Did you
know the Andes grow about 1 centimetre higher every year? Visitors say visiting the Rainbow Mountain feels like
stepping into a magical world!
The colourful lines come from different rocks under the ground. For example, iron (铁) in the rocks turns red
when it meets air, and a yellow material called sulfur (硫磺) makes the bright yellow lines. Over thousands of years,
wind and rain slowly washed away dirt and ice, showing these colourful parts. Scientists say it’s like nature is an
artist! The colours also change with the weather—they look bright in sunlight and softer on cloudy days.
Before 2015, the Rainbow Mountain was covered in ice. When the ice turned into water because of warmer
weather, the colours became perceptible (看得出的). Now, many travellers visit it every year. But too many people
walking here can harm the mountain. To protect it, local villagers control the number of visitors and ask everyone
to follow simple rules, like taking rubbish home.
The Rainbow Mountain reminds us that earth’s wonders are both beautiful and easily harmed. Saving these
places helps plants, animals, and people who live close by. Everyone can help! If we treat nature kindly, we can
protect the mountain. Helping local guides means villagers can protect their home better, and telling friends about
the Rainbow Mountain teaches others to care too. Even small steps today can keep this colourful wonder safe for
tomorrow.
27．What can we know about the Rainbow Mountain?
A．It has three bright colourful lines. B．It is the highest mountain chain on earth.
C．It is part of the Andes and over 5,000 metres tall.
28．What does the underlined word “it” in Paragraph 3 refer to?
A．The ice. B．Warmer weather. C．The Rainbow Mountain.
29． What’s the main theme of the passage?
A．Science. B．Nature. C．Travel.
30． What’s the writer’s purpose of writing the passage?
A．To introduce a natural place and call for its protection.B．To describe the reasons for rock colours in nature.
C．To encourage people to visit the Rainbow Mountain.
