| Waiting for Dr. Dirkson (A play) THE SCENE: A classroom in a high school. (场景) Summer is over. This is the first day of school. The students arrive one by one or in small groups. Everyone stops to read the sign on the door. It says: PHYSICS 1, DR.F. DIRKSON. THE CHARACTERS: Five students (Linda, Ben, Rudy, Tony, Molly) and Dr. Dirkson. (人物) Linda: Dirkson? Dirkson? I don't know that name. Who is he? Rudy: Don't ask me. He must be a new teacher. I don't remember him teaching in this school last year. Do you, Ben? Ben: No, but here comes Tony. If anyone can tell you about Dr. What's-His-Name, Tony can. He knows everything. Tony: (laughs.) I don't know everything. I only know almost everything. What is your question, please? Molly: What do you know about this new teacher? Tony: I don't really know much about Dr. Dirkson. I do hear things, though. I hear lots of things. Rudy: What do you hear? Is he a good teacher? I'm hoping to go to college. This class is important to me. Tony: I have a friend who goes to Central High School. I'm almost sure that's where Dr. Dirkson comes from. If it's the same teacher, he is rough. Believe me, he is rough and tough. Linda: What do you mean 'rough and tough'? I plan to go to college, too. I have to do well in this class. Tony: What I hear is that Dirkson's exams are very hard. He usually fails about half the class. All the girls. Linda: (angry) That can't be true. You're making it up, Tony. Molly: He's just talking like that to make us angry, Linda. Tony, What does Dr. Dirkson look like? Is he married? Tony: I don't think so. But don't get excited, Molly. He isn't going to interest you. He's about seventy-seven years old and he uses a walking stick. Molly: (she is angry) Tony, why do you say that this teacher fails all the girls? Do you think physics is too hard for girls? Do you think we can't do it? Tony: All I'm saying, Molly, is that girls don't make it in Dr. Dirkson's class. Physics is very difficult. It's not like art or music or history. It's a science. How many famous women scientists are there? Hardly any. You can count them on the fingers of one hand. Ben: That's not fair(公平), Tony. There are many women who are doctors and engineers and scientists. And there are more of them all the time. Rudy: That's right, Tony. I agree with Ben. Girls can do anything we can do. Tony: I don't care what anybody says. I'm telling you the truth, Molly. I'm not saying that girls are not intelligent (有智力的). They just don't have the right kind of intelligence to understand physics. Dr. Dirskson must know that. Take my advice (忠告) and get out of his class before he walks in. (A very pretty young woman hurries into the classroom.) Dr. Dirkson: Good morning. I'm sorry I'm late. I am Dr. Dirkson. (The whole class starts to laugh. Everyone laughs hard. Everyone except Tony.) |
