[单项选择]Practically speaking, the artistic maturing of the cinema was the single-handed achievement of David W, Griffith (1875-1948). Before Griffith, photography in dramatic films consisted of little more than placing the actors before a stationary camera and showing them in full length as they would have appeared on stage.

To understand how this transformation has taken place we must briefly look back at our forefathers. They spent over a million years evolving (进化) as cooperative hunters. Their very survival depended on success in the hunting-field. Under this pressure their whole way of life, even their bodies, became greatly changed. They became chasers, runners, jumpers, aimers, throwers and prey-killers. They cooperated as skillful male-group attackers.
