In 1960, the first Chinese team reached the top of Qomolangma from the northern side. 2. In 1975, another Chinese team brought a ladder to the Second Step. 3. In 2020, a Chinese team measured the height of Qomolangma – 8,848.86 metres. 4. A climber must be strong and brave. 5. A good climber can stay calm in dangerous situations. 6. Before 1960, no one could climb from the northern side. 7. Climbing Qomolangma is extremely dangerous, but people still do it. In 1960, a Chinese team succeeded even though others called the northern side the “Death Road”. I think climbers must have great determination and teamwork. They also need to be able to deal with terrible weather and thin air. Why do they take such risks? Perhaps because human curiosity cannot be stopped. As George Mallory said, “Because it’s there.” 1 学科网（北京）股份有限公司 $
