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, the longest mountain chain on the earth. Visitors say going to Rainbow Mountain feels like stepping into a magical world.
The colourful lines come from different rocks under the ground. For example, iron in the rocks turns red when it meets air, and a yellow material called sulfur makes the bright yellow lines. Over thousands of years, wind and rain slowly washed away dirt and ice, showing these colourful parts. Scientists say nature is like an artist! The colours also change with the weather—they look bright in sunlight and softer on cloudy days.
Before 2015, Rainbow Mountain was covered in ice. When the ice turned into water because of warmer weather, the colours became perceptible. Now, many travelers 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 away.
Rainbow Mountain reminds us that the earth's wonders are both beautiful and easily harmed. Saving these places helps plants, animals and people who live close by. Everyone can help! Even small steps today can keep this colourful wonder safe for tomorrow.

【分析】
本题为英语阅读理解选择题，共5小题，需根据原文内容逐一分析选项，通过定位原文对应信息、对比选项与原文表述、结合语境猜测词义、判断作者意图等方法，排除错误选项，确定正确答案。
【解析】
31. 细节理解题：定位原文第一段，根据“It is part of the Andes Mountains”可知，彩虹山属于安第斯山脉，故B正确。A选项原文提到四种颜色（红、黄、绿、紫），并非三种；C选项安第斯山脉是世界最长的山脉链，而非最高；D选项原文未提及每天能看到彩虹，均错误。
32. 主旨大意题：第二段主要讲述彩虹山的颜色来自地下不同岩石（如铁遇空气变红、硫形成黄色），以及风化侵蚀露出彩色部分，核心是说明颜色形成的原因，故A正确。B选项仅为段落部分内容，C、D与段落主旨无关。
33. 词义猜测题：根据第三段语境，2015年前彩虹山被冰覆盖，冰融化后颜色变得清晰可见，perceptible意为“可感知的、清晰的”，对应选项C（Clear）。A（自然的）、B（可变的）、D（黑暗的）均不符合语境。
34. 细节理解题：定位原文第四段，根据“local villagers control the number of visitors and ask everyone to follow simple rules”可知，当地村民通过制定规则（如带走垃圾）、控制游客数量来保护彩虹山，故C正确。A是之前的状态，B与原文不符，D并非禁止游客进入，均错误。
35. 作者意图题：文章前半部分介绍彩虹山的位置、颜色成因等自然特点，后半部分呼吁保护彩虹山，故作者目的是介绍自然奇观并呼吁保护，D正确。A、B、C均片面或不符合原文。
