Why does the student go to see the professor? [br] Listen again to part of the conversation. Then answer the following question. What does the professor mean when she says this?
Listen to a conversation between a student and a professor. (P = Professor, S = Student)
P: OK, Karl. How could I help you?
S: It’s about my term paper of the urban planning class. Instead of doing library research, I was thinking of doing a survey of my own and using the data in the report.
P: That’s a nice idea. I think doing this kind of hands-on project is great experience, especially if you decided to go to graduate school.
S: But I have been having a lot of problems designing a survey.
P: Ah, it’s not as easy as it looks, is it?
S: No. Now I am not even sure if I can stick with my plan or switch back to a more traditional paper.
P: Well, you might as will get some experience sooner rather than later What’s the topic again?
S: Nothing really complex. I just wanted to survey local people about the proposal for widening route 62 from a two-lane road to four-lane highway.
P: OK.
S: So how do I go about selecting the people I want to survey? A lot of what I read has stressed having a representative sample. But I’m not sure how to do it.
P: Well, yes. A representative sample is crucial. You want the people you survey to be as close to an accurate reflection of the larger population you’re interested in as possible. Imagine that the town is a cake with raisins in it and imagine that for some reason, most of the raisins end up on one side of the cake. If you cut a piece from the other side, would that be truly representative? Would that be an accurate reflection of the cake?
S: No. You’ll be missing the raisins.
P: Exactly! So for your project, what if you only survey people who live in houses along route 62, you think that would be useful?
S: Well, no. Because everyone there would probably be opposed to the widening.
P: Yes. And that’s why a representative sample is important. You don’t want a sample that’s biased, too strongly one way or the other. So, how do you do that?
S: Well, I could make sure my survey reaches people in all parts of the town.
P: Good. So how can you do that?
S: Well, I would go and make phone calls, just choose numbers at random from the local phone director instead of passing on questionnaires, because people often don’t mail them back. But I don’t see how I could get a representative sample using the phone.
P: Well. Make sure you’re getting a nice balance of numbers. Phone company can tell you what numbers have been assigned to different parts of town. For example, for numbers in my neighborhood, that was a 256 and I live on the edge of town, where I guess you’d find a lot of pro-highway people. So make sure you don’t call mostly 256 numbers.
选项
A、The student should not change his plan.
B、The student has little time to finish the project.
C、The student should have spoken with her earlier.
D、The student needs more experience at writing traditional papers.
答案
A
解析
学生在纠结是继续坚持自己的调查,还是回到常规的做法时,教授说出了录音中的那句话。接着,教授开始问学生的调查主题和遇到的困难,并提供了自己的建议。由此可见,教授说录音中的这句话的意思是让学生继续坚持,不要更改他的计划,故选A项。B项“学生没有时间完成项目”和C项“学生应该早点跟她说”都与教授说的这句话毫无关系。D项“学生在写常规论文方面需要更多的经验”只是利用experience和traditional等词拼凑出来的干扰项,具体内容在对话中没有体现。
