I went to Grand Canyon (大峡谷) National Park in July 2012 for the first
time and I knew I wanted to work there as a park ranger（管理员）. Park rangers protect the park's animals, plants, land, buildings, and
people.
Now, as a park ranger for
Grand Canyon National Park, I share the science, history and beauty of this park
with thousands of visitors from around the world.
National parks are like outdoor
museums. Park rangers have all kinds of jobs, depending on where they work and what
they studied during college. I teach school field trips（实地考察）, work at visitor centers and help
people stay safe during their visit.
My favorite part of my job
is showing children their first look at the Grand Canyon during school field trips.
Children are often amazed at the canyon's size and colors. Sometimes, they think
it looks like a painting.
Being a park ranger requires
a lot of energy. I walk several miles and talk with hundreds of people each day.
Park rangers must enjoy working with people and speaking in front of groups. Nearly
5 million people visit Grand Canyon National Park every year.
Park rangers must also be
prepared for any situation. Recently, I broke a traffic jam(堵塞). It was caused by a huge elk（麋鹿）standing in the road. Elks can become dangerous when they get scared,
so I asked visitors to stop their cars and take pictures from far away. Believe
it or not, I also help protect people from monkeys. It is not allowed to feed animals
in national parks. But sometimes, visitors try to feed monkeys.
