Bob likes climbing very much. However, there wasn't one climbing club in his school at first, so he felt sad.
At the beginning of the second year of middle school, his school offered rock climbing lessons in order to encourage students to exercise. He was so happy that he joined at once.
In the first lesson, the coach said, "Rock climbing needs strength, speed, courage and persistence（坚持）. All these are necessary." But in Bob's opinion, rock climbing was just a fun activity. It interested him.
During the following classes, the coach asked the students to run 1,000 metres first, and then climb with a rope. When Bob finished running, he almost lost his breath（呼吸）and got bored, and he even did not want to touch the rope. He thought it was less interesting than before. The coach noticed that and asked him, "Why do you want to take rock climbing lessons?" "I come for fun, of course." "Is that fun?" he asked. Bob shook his head slowly. The coach then explained patiently, "That's because you stop halfway. You know, beautiful sights are always on the top."
After hearing his words, Bob made up his mind to finish his journey. When he got to the top in the end, he felt really excited.
Sometimes it's hard to reach the top of the mountain, but it's a pity to stop halfway, so don't give up.
