概括大意与完成句子： The Storyteller 1.Steven Spielberg has always had one goal: to tell as many great stories to as many people as will listen．And that’s what he has always been about．The son of a computer scientist and a pianist, Spielberg spent his early childhood in New Jersey and, later, Arizona．From the very beginning, his fertile imagination filled his young mind with images that would later inspire his filmmaking． 　　 2.Even decades later, Spielberg says he has clear memories of his earliest years, which are the origins of some of his biggest hits．He believes that E．T．is the result of the difficult years leading up to his parent’s 1966 divorce, “It is really about a young boy who was in search of some stability in his life．”“He was scared of just about everything,” recalls his mother, Leah Adler．“When trees brushed against the house, he would head into my bed．And that’s just the kind of scary stuff he would put in films like Poltergeist．” 3.Spielberg was 11 when he first got his hands on his dad’s movie camera and began shooting short flicks about flying saucers and World War ΙΙ battles．Spielberg’s talent for scary storytelling enabled him to make friends．On Boy Scout camping trips, when night fell, Spielberg became the center of attention．“Steven would start telling his ghost stories,” says Richard Y．Hoffman Jr．, leader of Troop 294, “and everyone would suddenly get quiet so that they could all hear it．” 4.Spielberg moved to California with his father and went to high school there, but his grades were so bad that he barely graduated．Both UCLA and USC film schools rejected him, so he entered California State University at Long Beach because it was close to Hollywood．Spielberg was determined to make movies, and he managed to get an unpaid, non-credit internship（实习）in Hollywood．Soon he was given a contract, and he dropped out of college．He never looked back． 5.Now, many years later, Spielberg is still telling stories with as much passion as the kid in the tent．Ask him where he gets his ideas, Spielberg shrugs．“The process for me is mostly intuitive (凭直觉的),” he says．“There are films that I feel I need to make, for a variety of reasons, for personal reasons, for reasons that I want to have fun, that the subject matter is cool, that I think my kids will like it．And sometimes I just think that it will make a lot of money, like the sequel(续集) to Jurassic Park．”Spielberg says he makes movies for ________.
