一、阅读短文，回答问题
It's the tallest peak (山峰) on earth. Here, you can see snowy mountains shine under the blue sky. You can take a breath of the freshest air. Welcome to Mount Qomolangma (珠穆朗玛峰)!
The name "Qomolangma" means "mother of the universe". It stands on the border (交界) between Nepal and China. Mount Qomolangma is part of the Himalayas. It is 8,848.86 metres high above sea level, reaching into the sky as high as airplanes fly.
Every year, hundreds of climbers from all over the world come here. The first two people to reach the top were Edmund Hillary from New Zealand and Tenzing Norgay from Nepal. They made history by climbing the mountain in 1953.
The weather there is always very cold and windy. There is snow everywhere. The wind blows all year long. In winter, the lowest temperature can reach -50℃. There is very little oxygen on the mountain. Not many animals can live there, although you can see some yaks (牦牛). Yaks have long hair to keep them warm. They are very strong and able to walk on narrow paths. People call yaks "the ships of the highlands".
