A. 回答问题
请阅读下面短文，根据所提供的信息，回答五个问题。要求所写答案语法正确、信息完整切题。
If you are a nature lover, you must visit Zhangye Geopark(地质公园) in China! It’s one of the best geoparks in the world. Here, you can enjoy the beauty of the rainbow-coloured hills(山丘).
The hills are low. They look like waves and have many
different colours, just like a rainbow! You may wonder
how these colourful hills came to be. Millions of years ago,
this area was under a lake. Over time, rivers brought in sand and stones with different kinds of metal elements(金属元素). These were left in layers(表层) on the bottom of the lake. Some layers were red, some yellow, and others turned purple or blue. Later, as the climate became colder and drier, the lake dried up. Then, something amazing happened!
The underground land began to rise and push against each other. The layers of sandstone were lifted higher and higher. Through years of wind, sun, and rain, the layers formed the hills we see today.
The colourful hills attract many visitors! June to September is the most wonderful time to visit the park. The mornings and evenings are cool, giving you the perfect weather to enjoy the sunrises and sunsets. Sunshine after a summer rain makes the colours even brighter.
