【正确答案】正确答案：Most of Shakespeare"s plays are in the format of 5 acts. Act 1 is the exposition, in which thedramatis personae are presented, and time and place are established. We learn about the antecedents of the story. Act 2 is the complications in which the course of action becomes more complicated, the "tying of knots" takes place. Act 3 is the climax of action in which the development of conflict reaches its high point. Act 4 is reversals where the consequences of Act 3 play out, momentum slows, and tension is heightened by false hopes or fears. Act 5 is the catastrophe in which the conflict is resolved, whether through a catastrophe, the downfall of the hero, or through his victory and transfiguration. The format of five-act play is common in Shakespeare"s plays, and is grounded in the concepts of unity in Aristotle"s Poetics.
