On a Wednesday night, a young man was playing the guitar at the station. Some people stopped and put some money into his hat.

    The next day, the young man came to the station again. There was a large piece of paper next to his hat. It said, "Last night, a kind man named Henry put something important into my hat. Please come to get it back soon."

    About half an hour later, an old man came and the young man said, "Yes, I knew you would come back."

    "What did you lose?" asked the young man. "$800, 000," answered the old man. Then the young man took out a check（支票）and gave it back to the old man. The old man was so happy that he danced with the young guitar player.

    Imagine a boy from a small village in East Africa. He has been looking after cows from a very early age. At twelve, he knows more about cows than most of us. {#blank#}1{#/blank#} Has this boy ever had any education?

    Education is discovering about ourselves and about the people and things around us. All the people who care about us—our parents, brothers, sisters, friends—are our teachers. {#blank#}2{#/blank#} We start learning on the day we are born, not on the first day we go to school. Every day we have new experiences, like finding a bird's nest(巢), discovering a new street in our neighborhood and making friends with someone we didn't like before. {#blank#}3{#/blank#} Encouragement from the people around us makes it possible for us to discover things as much as possible. As we grow up, we begin to find out what we are able to do. We may be good at cooking, or singing or playing football. {#blank#}4{#/blank#} Just thinking about cooking doesn't tell us if we are good at it.

We learn so much just in our daily life. {#blank#}5{#/blank#} Of course we can learn some things better at home than at school, like how to do the shopping, and how to help old or disabled people who can't do everything for themselves. At school, teachers help us to read and write. With their help, we begin to see things in different ways.

    What can we do to help protect the environment? It seems useless to just pick up a piece of trash(垃圾) ,but what will happen if you keep doing it every day? Tommy Kleyn, an ordinary man from the Netherlands, may give you the answer. Tommy Kieyn walked past a polluted river on his way to work every day. It used to be a beautiful view, but the trash on the bank made it dirty and smelly. So Tommy decided to pick up the trash along the river a little bit at a time after work. "It took me about 30 minutes to fill one garbage(垃圾) bag with trash, but one garbage bag didn't seem helpful in a place as polluted as this. I decided to fill one bag of trash each day as I passed by," Tommy said. Every day, Tommy took pictures of the river and shared them on his Facebook page. To his surprise, in just six days, he had made great progress with his cleanup effort(努力) . He felt happy and kept doing it. Gradually, more and more people knew about Tommy's story. Other people in the community began following in his footsteps and cleaning up trash on their way home, too. "The idea is to encourage people to fill one garbage bag with litter each day. It only takes 30 minutes, but it really makes a difference and you will be amazed at how good you feel afterwards, "he said. People from all over the world have been moved and inspired(激励)by Tommy's story. No effort is useless if we keep doing it every day. Ordinary people like you and me can also make a difference to the world we live in if we take actions right now.

I went to Grand Canyon (大峡谷) National Park in July 2012 for the firsttime 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, andpeople.

Now, as a park ranger forGrand Canyon National Park, I share the science, history and beauty of this parkwith thousands of visitors from around the world.

National parks are like outdoormuseums. Park rangers have all kinds of jobs, depending on where they work and whatthey studied during college. I teach school field trips（实地考察）, work at visitor centers and helppeople stay safe during their visit.

My favorite part of my jobis 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 thinkit looks like a painting.

Being a park ranger requiresa 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. Nearly5 million people visit Grand Canyon National Park every year.

Park rangers must also beprepared 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. Believeit or not, I also help protect people from monkeys. It is not allowed to feed animalsin national parks. But sometimes, visitors try to feed monkeys.
