资料题：What do local theatres NOT do for the theatre industry（  ）。

The local theatre has its special ways of drawing crowds.Unlike the Broadway performances that cater to the elite stratum, dedicating to the subtle intricacies of the theatrical traditions and highlighting the glamour of famous actors or actresses, the local theatre targets the local communities, elaborates on the general drama of human interaction, and relies on local participants at different levels.Although the local theatres are rarely large-scale affairs, they perform the important function of bringing communities into the art of drama.There are multiple levels in the performance-audience relationship.The metropolitan audience regards the professional troupe as devoted actors, almost invisible behind the performances.In this case, the relation is one of purely subject object.On the other hand, the local spectators are drawn to the amateur productions readily because they are familiar with the performers personally.Thus, besides the relationship between the spectacle and the viewers there is a compassionate connection among or between those on the stage and those in the auditorium.Since the source of the local theatre is located within the community and dependent upon volunteers, frequently the local inhabitants have opportunities to contribute to the actual process of production.The corroboration(确证)from the local community furthers the popularity of theatre as a whole, and sometimes even decreases the expenditure of the theatre.This warm invitation of participants in the theatrical production reverses the golden rule of managing a magnanimous Broadway theatre, where only a few fully trained professionals can have access to the wonder of the stage.
