Do you know any 9-year-olds who have started their own museums? When Theodore Roosevelt was only nine, he and two of his cousins opened the "Roosevelt Museum of Natural History". The museum was in Theodore's bedroom. It had a total of 12 specimens. On display were a few seashells, some dead insects, and some birds' nests. Young Roosevelt took great pride in his small museum.

    Born in New York in 1858, Theodore Roosevelt was not always healthy. "I was a sickly boy", he once wrote. Roosevelt had a health condition called asthma. He often found it hard to breathe. Instead of playing, he watched nature and then read and wrote about it.

    Roosevelt's interest in nature sometimes got him into trouble. Once, his mother found several dead mice in the icebox. She demanded that the mice be thrown out. This was indeed "a loss to science", Roosevelt said later.

    Because Roosevelt was often sickly as a boy, his body was small and weak. When he was about 12, his father asked him to improve his body. Roosevelt began working out in a gym. He didn't become strong quickly. But he did decide to face life's challenges with a strong will. That determination stayed with Roosevelt his whole life. And eventually his body did get strong. As an adult, he was an active and healthy person. He enjoyed adventures, and he loved the outdoors.

    A toy company named the teddy bear for Theodore "Teddy". After knowing that, Roosevelt refused to shoot a baby bear while hunting.

    In 1900, at the age of 41, Roosevelt was elected Vice President. A year later, President McKinley, was shot and killed. Roosevelt became our 26^th President. At 42, he was the youngest leader the country had ever had.

    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.
