[单项选择] Acting is such an over-crowded profession that the only advice that should be given to a young person thinking of going on the stage is "Don’’t!". But it is useless to try to discourage someone who feels that he must act, though the chances of his becoming famous are slim. The normal way to begin is to go to a drama school. Usually only students who show promise and talent are accepted, and the course lasts two years. Then the young actor or actress takes up work with a repertory company, usually as an assistant stage manager. This means doing everything that there is to do in the theatre: painting scenery, looking after the furniture, taking care of the costumes, and even acting in very small parts. It is very hard work indeed. The hours are long and the salary is tiny. But young actors with the stage in their blood are happy, waiting for the chances of working with a better company, or perhaps in films or television. Of course, some people have unusual chances which lead to
A. actors are very unusual people
B. the course at the drama school lasts two years
C. acting is really a hard job
D. there are already too many actors
