I fell in love with Yosemite National Park the first time I saw it, when I was 13. My parents took us there for camping. On the way out, I asked them to wait while I ran up to E1 Capitan, a  16  rock of 3,300 feet straight up. I touched that giant rock and knew  17 I wanted to climb it. That has been my life’s passion (钟爱) ever since 18 the rocks and mountains of Yosemite. I’ve long made Yosemite my  19 .
About 15 years ago I started seeing a lot of  20 , like toilet paper, beer cans, and empty boxes, around the area. It’s   21  me why visitors started respecting the place 22 and treated such a beautiful home-like place this way.
I tried  23  trash(垃圾)myself, but the job was too big. I would  24  an hour or two on the job, only to find the area trashed all over again weeks later. Finally, I got so  25  it that I decided something had to change.
As a rock-climbing guide, I knew 26  about organizing any big event. But in 2004, together with some climbers, I set a date for a 27 . On that day, more than 300 people  28 . Over three days we collected about 6,000 pounds of trash. It was amazing how much we were able to  29 . I couldn’t believe the  30  we made—the park looked clean!
Each year volunteers come for the cleanup from everywhere. In 2007 alone, 2,945 people  31 42,330 pounds of trash.
I often hear people  32   about their surroundings. If you are one of them, I would say the only way to change things is by     33 rather than complaining. We need to teach by  34   . You can’t blame others  35  you start with yourself.

When I was a boy, I belonged to the Boy Scouts(童子军)，so I used to go camping every summer, and once something happened which I have never been able to explain.

We were camping in a place above a river. After arriving, we all rushed down to the river and had a swim. Standing by the river, we noticed that it was surrounded by cliffs (悬崖).If someone wanted to reach the river at this point, he had to walk past our camp.

Several days later, the scoutmaster had to be away for a day. That afternoon, we had supper early. We were sitting round the fire, eating and talking, when a man walked past and went down towards the river. We all felt that this man looked very strange, but, because each of us was afraid of looking very stupid, no one said anything.

We ate rather slowly, taking as long as possible. After finishing, we collected our plates together so that we could take them to the river where we always washed them.  But no one moved towards the river, we stood looking at each other ashamed. Then all shouting at once, we began talking about the man who had walked past us. We agreed how strange he looked and we wondered what he could be doing by the river. We knew that he could only return by passing through our camp.

An hour passed. Then one of the boys suggested we should creep(悄悄移动)down by the river so that we could see what the man was doing. Moving very slowly and keeping in the shadow, we crept down towards the bank. One boy climbed a tree so that he could see everything clearly. He called to us that there was no one there, so we ran down to the bank, looking everywhere carefully. We could not understand where the man had gone.

When it got dark, we went back to our camp feeling bewildered. We told the scoutmaster what had happened in the evening. Smiling, he doubted that we had seen the man, but finally suggested we go and look again. We did, but there was no one there.

Many years have passed, but I still remember it as if it were yesterday. What did we see? I do not know.
