完形填空。      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   1   rock
of 3,300 feet straight up. I touched that giant rock and knew    2   I wanted to climb it. That has
been my life"s passion (钟爱) ever since---    3   the rocks and mountains of Yosemite. I"ve long
made Yosemite my    4  .
     About 15 years ago I started seeing a lot of    5  , like toilet paper, beer cans, and empty boxes,
around the area. It"s    6   me why visitors started respecting the place    7  and treated such a

     I tried   8   trash(垃圾)myself, but the job was too big. I would   9   an hour or two on the
job, only to find the area trashed all over again weeks later. Finally, I got so    10   it that I decided
something had to change.
     As a rock-climbing guide, I knew   11  about organizing any big event. But in 2004, together with
some climbers, I set a date for a   12  . On that day, more than 300 people    13  . Over three
days we collected about 6,000 pounds of trash. It was amazing how much we were able to   14  . I
couldn"t believe the    15   we made ---the park looked clean!
     Each year volunteers come for the cleanup from everywhere. In 2007 alone, 2,945 people picked up
42,330 pounds of trash and    16 132 miles of roadway.
     I often hear people    17   about their surroundings. If you are one of them, I would say the only
way to change things is by    18   rather than complaining. We need to teach by   19   . You
can"t blame others    20   you start with yourself.
