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. 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. “ 只有 ”，引导条件状语从句 be determined to do sth. 决心做某事 相当于 little by little Post-reading 8 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 reseach team went to Qomolangma to measure its height—8,848.86 metres. 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” ! risk one’s life to do sth. 冒着生命危险做某事 “ 不能被阻挡” Post-reading Group work. Discuss the questions. 1.How do you think the Chinese climbers felt when they placed the national flag on top of Qomolangma? 2.What do you think George Mallory meant by “because it’s there”? 3.What qualities do you think a good mountain climber needs to have? 1e They felt proud, excited, and a sense of responsibility. It means humans are driven by curiosity and the desire to explore, even if the challenge is dangerous. Determination, courage, teamwork, and physical strength. Post-reading If we meet any difficulties in our life, what can we do? We can stay calm and don’t be afraid of the difficulties. We can think of good ways to solve the problems step by step. We can learn from the climbers and keep trying, never give up. We can believe in ourselves—we are always stronger than difficulties. ...
