托福og3听力What is mentioned as an advantage of working on this project? 答案解析

[00:00.00]Listen to a conversation between a student and a professor.
[00:04.47]Student: Hi, Professor Archer, you know how in class last week you said that you were looking for students who are interested in volunteering for your archeology project?
[00:12.59]Professor: Of course, are you volunteering?
[00:14.55]Student: Yes, I am. [00:15.48]It sounds really interesting, but um… do I need to have any experience for these kinds of projects?
[00:21.45]Professor: No, not really.[00:22.76]I assume that most students taking the introductory level class would have little or no experience with archeological research, but that’s ok.
[00:31.07]Student: Oh, good, that’s a relief. [00:33.08]Actually, that’s why I’m volunteering for the project - to get experience. [00:37.50]What kind of work is it?
[00:39.16]Professor: Well, as you know, we're studying the history of the campus this semester. [00:43.79]This used to be an agricultural area and we already know that where the main lecture hall now stands, there once were farm house and barn that were erected in the late 1700s. [00:54.67]We are excavating near the lecture hall to see what types of artifacts we find, you know, things people used in the past that got buried when the campus was constructed. [01:04.49]We’ve already begun to find some very interesting items, like old bottles, buttons, pieces of clay pottery.
[01:11.73]Student: Buttons and clay pottery? [01:13.23]Did the old owners leave in such a hurry that they left their clothes and dishes behind?
[01:18.08]Professor: Hmmm… that’s just one of the questions we hope to answer with this project.
[01:22.23]Student: Wow, and it’s all right here on campus.
[01:24.62]Professor: That’s right, no traveling involved. [01:27.09]I wouldn't expect volunteers to travel to a site, especially in the middle of the semester. [01:31.68]We expect to find many more things, but we do need more people to help.
[01:36.15]Student: So… how many student volunteers are you looking for?
[01:40.07]Professor: I’m hoping to get five or six. [01:41.82]I’ve asked for volunteers in all of the classes I teach, but no one has responded. [01:46.15]You are the first person to express interest.
[01:48.23]Student: Sounds like it could be a lot of work. [01:50.87]Is there um… is there any way I can use the experience to get some extra credit in class? [01:56.12]I mean, can I write a paper about it?
[01:58.34]Professor: I think it’ll depend on what type of work you do in the excavation, but I imagine we can arrange something. [02:05.10]Actually I’ve been considering offering extra credit for class because I’ve been having a tough time getting volunteers. [02:11.86]Extra credit is always a good incentive for students.
[02:15.44]Student: And how often would you want the volunteers to work?
[02:18.80]Professor: We’re asking for three or four hours per week, depending on your schedule. [02:23.01]A senior researcher, I think you know John Franklin, my assistant, is on site every day.
[02:28.58]Student: Sure, I know John. [02:29.94]By the way, will there be some sort of training?
[02:33.02]Professor: Yes, er… I want to wait till Friday to see how many students volunteer, and then I’ll schedule a training class next week at a time that’s convenient for everyone.
[02:42.37]Student: Ok. I’ll wait to hear from you. [02:44.43]Thanks a lot for accepting me.
