Dear Miss Li,

    I'd like to thank you for give money to Animal Helpers. I'm sure you know that this group was set up to help disable people like me. You helped to make that possible for me to have Lucky. Lucky makes a big different to my life.

    I can't use my arms and legs well. So normally things like answering the telephone, opening and closing doors, or carrying thing are difficult for me. Then last year, to cheer me up, a friend of mine came up with a plan and helped to get me a special training dog Lucky from Animal Helpers. Lucky is clever and he can understand me when I give to him orders. I also feel lucky to have the “dog helper” because your kindness. Thank you again for changing my life.

Best wishes,

Ben Smith

    Annie Oakley was born in 1860 in Darke County, Ohio. Her family was very poor. She decided to help family even when she was young, so she learned to use a gun, and began hunting animals for food. She could shoot them without losing the important parts of the meat.

    Soon her shooting ability became well known. When she was sixteen, she was invited to a competition with a famous marksman(神枪手) , Frank Butler. Annie surprised everyone by winning the competition. Later that year she and Frank married.

    In 1882 Annie Oakley and Frank Butler started putting on shows together. Frank Butler was the star of the show and she was his assistant. The famous native American leader, Sitting Bull, thought so highly of her shooting ability that he called her "Little Sure Shot". Later Annie Oakley became the star of the show and Frank Butler was her assistant. Posters （海报）for the show called her the "Champion Markswoman".

    During World War I, Annie Oakley wanted to train a group of women volunteers for the army, but the United States did not accept it. She gave American soldiers shooting lessons, and traveled across the country visiting many training camps. She gave shooting performance and raised money to support the American soldiers.

    Annie Oakley died on November 3, 1926. Eighteen days later, Frank Butler died too.
