In 1920, barely out of his teens, Alfred Hitchcock went to work for an American film company which had opened a studio in Islington, London. His first job at the studio was writing captions (脚本) for silent movies. Within two years, he was writing scripts(剧本) and working as an assistant director. For the rest of the 1920s, Hitchcock worked on one film after another in Britain and Germany. Filming was often a rough-and-ready(匆忙做成的) affair and the assistant director was required to step in and plug gaps. A cameraman went missing, Hitchcock became a cameraman. A scene needed rewriting, Hitchcock rewrote it. Someone needed to be in charge of money when the film crew was on location, Hitchcock looked after the money. At the same time, this being the era of silent movies, Hitchcock was learning the language of cinema: telling a story-not through dialogue, but through visual images(视觉影象). This led to his success later. When he began to direct his own films, first in Britain and later in Hollywood, he was determined to make films that held the audience's attention and kept tension(紧张感). He succeeded. Hitchcock's ability to put you on the edge of your seat makes him one of the greatest makers of suspense(悬念) movies. (以下为试题题干)He had taken up different jobs before he succeeded.()
