Stretching about 446 kilometres long and over 1,800 metres deep, this huge canyon was formed by the Colorado River over millions of years. Its colourful rock layers show Earth’s long history, with some rocks being more than 2 billion years old. 刷外刊·刷时文 返回目录 7 About 5 million visitors come each year to see the Grand Canyon’s wonderful views. The canyon’s colours change during the day—golden in the morning, deep red at midday, and orange in the evening. Many walk the Bright Angel Trail or fly over the canyon. The South Rim is popular, with great views like Mather Point. The Grand Canyon isn’t just rocks—many animals live there too. Visitors might see bald eagles flying, reindeer eating grass, or bighorn sheep climbing on rocks. The Colorado River has special fish like the humpback chub, which is endangered （濒危的）.This shows how the whole environment is connected. 刷外刊·刷时文 返回目录 In 1919, the Grand Canyon National Park was set up to protect this natural wonder. Now, park workers help keep it clean and safe by teaching visitors to stay on paths, not leave trash, and not disturb animals. Problems like climate change and too many visitors could damage this special place, so protection is very important. The Grand Canyon shows nature’s power and beauty. It teaches us Earth’s history and why we must protect it. Sustainable （可持续的） tourism keeps it safe for the future.#7 阅读理解·语篇导读 本文主要介绍了美国亚利桑那州的科罗拉多大峡谷的自然景 观、地质历史、生态多样性以及保护措施。 刷外刊·刷时文 返回目录 1.What does the word “Stretching” most probably mean in the first paragraph?( ) A A.Extending.
