听力原文：M: I had thought to drop in and find out exactly where I went wrong with this las

t paper. Do you remember marking it？

W: Yes I do and… well, my impression was that you were trying to connect argument after argument without any grounds to support each assertion.

M: But surely, you would agree that there simply isn’t a lot of research out there to support my arguments.

W: Ah, but research is only one way to back up an argument.

M: May I know what other things I can use？

M: For starters, your experiences. Experiences form. the basis for conclusion. Then perhaps try to look at analogies to see all that can help you.

W: Are there any guidelines available on how I can use these experiences and analogies？

M: I did give a whole lecture on it dated February 7. You were there; weren’t you？

W: Whoops, that was one that fell on the week I couldn’t be there. I had to rush back home for personal reasons.

M: Well, perhaps on your next paper you’ll know that every argument you make needs legs or your paper will remain on the ground.

M: Thanks, Mrs. Morse. It’s all food for thought and you can bet the next one will have a solid base.

W: That’s the spirit.
