When I taught the introduction-to-theater course at North Dakota State University, I required my students to attend the university theater‘s current production and write a critique. After viewing a particularly fine performance, one student wrote: "The play was so real, I thought I was actually sitting on my couch at home, watching it on television."

　　我在北达科他州立大学教戏剧入门课时，要求学生们去看学校剧团当时的演出，并写一篇评论。看了一场极为精彩的演出后，一名学生写道：“这部戏剧是如此逼真，以致于我认为我自己是坐在家里的沙发上，从电视上看到的。”
