On the 1. _________ (high) place on earth, you will feel like you are able to touch the sky. But only the 2. _________ (good) climbers reach the top, and that is only if they survive the terrible conditions first. On the mountain, temperatures can fall to -30 degrees. Climbers must also deal with thin air, high cliffs, and 3. _________ (change) weather. Before 1960, no one was able to reach the top of Qomolangma from the northern side. Mountain climbers even called that way the "Death Road", but a Chinese 4. _________ (climb) team was determined to make the climb. On 24 May 1960, climbers Liu Lianman, Wang Fuzhou, Qu Yinhua, and Gong Bu arrived at the Second Step. It was 8,600 metres above sea level. People said it was 5. _________ high that even birds could not reach it. Liu allowed his teammates to step on his shoulders. Bit by bit, the climbers pulled themselves up, and they made it past the Second Step. At 4:20 a.m. on 25 May, the Chinese national flag flew above the 6. _________ (high) mountain in the world for the first time. In 1975, another Chinese team climbed to the top of Qomolangma to do research. This time, they brought a ladder to the Second Step. Until 2007, almost all climbers from the northern side used this "Chinese Ladder" to reach the top much faster. In 2020, a third team returned to Qomolangma to measure its 7. _________ (high) — 8848.86 metres. Climbing Qomolangma is 8. _________ (danger). Some climbers reach the top 9. _________ (success), but many fail. Why do people still risk their lives to climb the highest mountain in the world? It is because human curiosity and ambition cannot be stopped. Or, as the English explorer George Mallory put it, it is 10. _________ (simple) "because it's there"! $
