If you were to walk up Arthur Bonner and say, "Hey, Butterfly Man." his face would break into a smile. The title suits him and he loves it.

Arthur Bonner works with the Palos Verdes blues butterfly, once thought to have died out. Today the butterfly is coming back—thanks to him. However, years ago if you'd told him this was what he'd he doing someday, he would have laughed, "You're crazy." As a boy, he used to be "a little tough buy on the streets". At the age of thirteen, he was caught by police for stealing. At eighteen, he landed in prison for shooting a man.

    "I knew it had hurt my mom," Bonner said after he got out of prison. "So I told myself I would not put my mom through that pain again."

    One day he met Professor Mattoni, who was working to rebuild the habitat for an endangered butterfly called EI Segundo blue. He saw the sign "Butterfly Habitat" and asked, "How can you have a habitat when the butterflies can just fly away?" Dr. Mattoni laughed and landed him a magnifying glass, "Look at the leaves. I could see all these caterpillars on the plant." Dr. Mattoni explained, " Without the plant, there are no butterflies."

    Weeks later, Bonner received a call from Dr. Mattoni, who told him there was a butterfly that needed help. That was how he met the Palos Verdes blue. Since then he's been working for four years to help bring the butterfly back. He grows astragalus, the only plant the butterfly eats. He collects butterflies and bring them into a lab to lay eggs. Then he puts new butterflies into the habitat.

    The butterfly's population, once almost zero, is now up to 900. For their work, Bonner and Dr. Mattoni received lots of awards. But for Bonner, he earned something more: he turned his life around.

    For six years now Bonner has kept his promise to stay out of prison. While he's bringing back the Palos Verdes blue, the butterfly has helped bring him back, too.

    Every year hundreds of people try to climb the world's highest mountain or walk through rainforests(雨林). Let's take a look at two of the 21st century's(世纪的) greatest adventurers(冒险家).

    A mountain climber

    Do you know that more than 4，000 people have climbed Mount Everest? Gerlinde is one of them. She is one of the world's greatest climbers and has climbed all the mountains over 8，000 meters in the world. It's difficult to climb mountains in cold weather, but Gerlinde loves it. She started climbing the mountains near her home as a teenager. When she left school, she became a nurse but always went climbing in her free time.

    An Amazon adventurer

    Ed Stafford is the first person to walk along the Amazon River from the mountains of Peru to the mouth of the river in Brazil. His journey took two years and four months. There are many dangerous animals in the rainforest. But Ed was lucky and he was only bitten(咬) by small insects(昆虫). On his trip, Ed had to look for fruit or catch fish each morning. Sometimes food was hard to find and Ed was often tired and hungry. So he used a radio to ask the people of the rainforest for food and help.

    Mary was afraid of the dark. She thought there were terrible monsters（怪物） in the dark. One day her aunt Valerie came to visit. Valerie was a brave woman. Mary wanted to be like her. So Mary asked her aunt, "Are you afraid of the dark?"

    "A lot of times" answered her aunt. "When I was small, I was afraid of staying in the dark."

    Hearing this, Mary felt better.

    "I know a secret not to be afraid of the dark. Some blind children told it to me."

    "Can you tell me?" asked Mary.

    "Of course! The secret is to change your eyes. Because blind children can't see, and their hands are their eyes. At night, if anything makes you afraid, close your eyes, get out of bed, and try to see what it is. But use your hands as eyes..."

    That night when Mary felt afraid of something in the bedroom, she closed the eyes of her face and opened the eyes of her hands. She went to touch it with her hands...

    The next morning, Mary ran into the kitchen.

There was a big smile on her face. "The monster is so lovely," she cried. "It's my toy dog!"

    Sammy looked out of the classroom window at a bird in a tree. He saw a worm (小虫) in the bird's mouth. "Wow!" he whispered as he looked at the bird eating the worm.

    "Sammy!" his teacher Mr. Maxwell said loudly.

    Sammy jumped and knocked his science book off his desk. Everyone in the class laughed and Sammy blushed. This was the third time today he had been caught not paying attention to the science lesson. It was just so easy to get distracted (分心的) when people read aloud from the science textbook!

    It wasn't that Sammy didn't like science. He loved to learn about machines, Earth and animals. He even thought bugs and plants were great. He wanted to go outside and see how a snake lived. He wanted to watch plants growing from the ground as they did last month. He just didn't want to read about these things.

    Sammy thought Mr. Maxwell would surely understand. "There was a bird with a worm in its mouth..." Sammy began. Then he saw the furious look on his teacher's face. Sammy decided that he had better stop talking before Mr. Maxwell became any angrier.
