听力原文：On today's program, I'll talk to Morris Stevenson, whose first film excited the audience. He also received excellent reviews from numerous critics. I, personally, would also like to give two thumbs up to this one! It is unusual for a new filmmaker to receive so much attention after directing just one film, but clearly film critics feel he has a certain gift to create something. He's visiting the city this week to speak to students at Green Diamond film school, and we are fortunate he has added us to his busy schedule, and is spending time with us as well. Thank you for joining us in this studio, Mr. Stevenson.
