Passage Five
Hollywood (好莱坞) Is a suburb of the city of Los Angeles (洛杉矶) in California. Until 1908 it was no more than a quiet village on the northern side of the city, but in that year William Selig, one of the first people to make films, set up a film-producing workshop (车间) in Los Angeles. By 1911, David and William Horsely had set up another one in Hollywood, and at about the same time oil was discovered in the neighborhood. Thus Hollywood quickly became a big district given over to the film industry and to oil wells (没井).
The early makers of films found Hollywood a good place for their work because of its clear, sunny, rain-free weather, which allowed pictures to be taken all the year round.

Today, when most films can be "shot" (拍摄) under cover by man made lighting, these adv
A. of the fine weather and varied scenery (景色) there
B. there were snow-capped mountains and the sea
C. oil was discovered in California
D. it was in the suburbs
