Whenever the sun dropped and the blue sky came up, my father and I used to climb the mountain n 71 my house. Walking together, my father and I used to have a lot of conversations through which I learned lessons f 72 his experiences. He always told me, “You should have goals like c 73 the mountain.” Without the mountain-climbing that we both enjoyed, we couldn’t have enough t 74 to spend together because my father was very busy. I r 75 got a lot from the mountain-climbing. It gave me time to talk with my father and to be in deep thought as well as develop my patience.
O 76 we climbed a very high mountain. It was so challenging for me because I was only ten years old. During the first few hours of climbing, I enjoyed the flowers and trees, and the birds’ singing. But as time p 77 , I got a pain in both of my legs. I wanted to stop climbing, but my father said to me, “You can always see a beautiful sky at the top of the mountain, but you can’t see it b 78 you reach the top. Only t 79 can you see all of the nice things, which is just like your life.”
At that time, I was too y 80 to understand his words. But later after that, I got to know the meaning of hope in life. I found myself standing at the top of the mountain, and the sky was as clear as crystal(水晶).
