【正确答案】
C
【答案解析】[听力原文] M: Can I ask you about your evening class? What class do you go to? W: Car maintenance. M: What night of the week is it on? W: Wednesday night. M: And how long does it last? W: Well, it's supposed to start at 6:00, but that's a bit of problem because people have difficulty getting through the traffic. So we start at 6:30 and then it goes on until 9 o'clock. M: And what was your reason for wanting to do the class? W: Well, I just bought my first car and I don't know anything about cars. So I thought it was a good opportunity to learn. I guess most people in the class are in the same situation. M: Urn, and what do you actually do? Do you bring the car along to the class? W: Yes, we do. And in the first part of the lesson, the first half hour, the man who runs the class will go through some particular part of the car, and we'll learn about it. And then we spend the rest of the time actually working on our own cars, the same problem. M: And how many people are there in the class? W: Um, I think 16, but three quarters of them are women. It's quite interesting because the man is obviously used to teaching man. And he always starts his sentence by saying, 'Wow, you chaps, hello...' And then he stops and says, 'Oh, and you women, er, you ladies, but...er...' M: Urn...sounds funny. What does the woman say about her evening class? 对话中，男士表示说想要了解女士在夜校课程中的一些事情，在知道了女士学习的内容为汽车保养后，男士又问她的上课时间，女士回答是周三晚上。由此可知，女士所上的课程是一周只上一次的。故答案为C。
