Tip 1: Identifying the passage’s structure helps you follow its logical flow. 7 To most people, Mount Qomolangma is one of the greatest wonders of the world. On the highest place on earth, you will feel like you are able to touch the sky. But only the best 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 changeable 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 climbing team was determined to make the climb. 1b Read Part. 1 and answer the questions. 1 2 ◆Why is it difficult to climb Qomolangma? terrible conditions a temperature of –30 degrees thin air high cliffs changeable weather the best climbers a strong body a strong mind ◆ Why did mountain climbers call the northern side of Qomolangma the “Death Road”? Why did they still want to make the climb? Because they wanted to show China’s strength and national pride to the world. ◆What achievements have the Chinese climbing teams made? On 24 May 1960, climbers Liu Lianman, Wang Fuzhou, Qu Yinhua, and Gongbu arrived at the Second Step. It was 8,600 metres above sea level. People said it was so 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 world's highest mountain 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 Chinese research team went to Qomolangma to measure its height—8,848.86 metres.

By telling about different events in different years. I think they felt extremely proud, excited, and a strong sense of national pride. It was a historic moment for China and a great achievement for human beings. How do you think the Chinese climbers felt when they placed the national flag on top of Qomolangma? 1b Read Part. 3 and answer the questions. Climbing Qomolangma is dangerous. Some climbers reach the top successfully, 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 simply “because it’s there”! 5 ◆Why do people risk their lives to climb Qomolangma? ◆What do you think George Mallory meant by “because it’s there”? He meant that the mountain itself is a challenge, and humans have a natural desire to overcome challenges and explore the unknown. It's a simple but powerful expression of human curiosity and ambition. Think further 1. What qualities do you think a good mountain climber needs to have? A good mountain climber needs to have strong willpower, courage, perseverance, physical strength, teamwork spirit, and respect for nature. 2. Why do humans keep exploring nature?
