Q1. How do you think the Chinese climbers felt when they placed the national flag on top of Qomolangma
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.
Evaluation
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”!
He meant that the mountain itself is a challenge, and people climb it just because it exists and represents a goal worth pursuing. It shows human curiosity and the desire to explore the unknown.
