It is believed that Huck Finn is based on (基于) a childhood friend of Mark Twain's. In fact, Twain was not alone in basing a fictional character (虚构的角色) on a real-life person.
Severus Snape/ John Nettleship
Severus Snape is a skillful wizard (巫师) teaching magic in Harry Potter. The writer, J.K. Rowling, once said that the character was based on a teacher of hers.
The teacher turned out to be John Nettleship, who taught Rowling chemistry. At first, Nettleship felt surprised. "I know I am a strict teacher," he said. "But I don't think I am as bad as Snape!" On second thoughts, however, he said that he was so ill-tempered that most of his students avoided making him mad. Also, he used to wear long hair and have an untidy lab. That sounds familiar to Harry Potter fans.
Alice /Alice Liddell
Famously, Lewis Carroll's Alice in Alice's Adventures in Wonderland is based on Alice Liddell.
Carroll was close to the Liddell family. One day, ten-year-old Alice asked Carroll to tell her a new story. Carroll began to create his famous tale of Alice and what happened after she fell through the rabbit hole. The little girl liked the story so much that she asked him to write it down. And the rest is history.
Dill /Truman Capote
In To Kill a Mockingbird, Harper Lee based Dill on her childhood friend, Truman Capote. Capote once said, "Lee was my best friend. Have you ever read To Kill a Mockingbird? I'm a character in that story! The story takes place just in the town where we lived!"
