Conversation 1
M: Last time we talked about the history of paper. But do you know what paper is used for?
W: Oh, that’s an easy question. Paper is used for newspapers, books, writing paper, envelopes, wrapping paper, paper bags…
M: Yes, actually only half of the paper that is made is used for such purposes. Have you got an idea about other uses of paper?
W: No, I’m afraid not.
M: There are many other uses. (1) Paper is very good for keeping you warm. Houses are often insulated with paper. You have perhaps seen homeless people asleep on a large number of newspapers.
W: Yes, I have. So they are insulating themselves against the cold.
M: You are right. In Finland, it is very cold in winter. It is sometimes 40 degrees Centigrade below zero. (2) The farmers wear paper boots in the snow. Nothing could be warmer.
W: Oh, that’s unbelievable.
M: Now more and more things are made of paper. We have had paper plates, cups and dishes for a long time. But now we hear that chairs, tables, and even beds can be made of paper.
W: Fascinating!
M: People have made paper boats, but they have not yet made paper planes or cars. (3) Just wait, they probably will.
W: Well, you have become an expert on paper. How do you know all that?
M: You know (4) I’m preparing for a presentation, so I’ve looked up a lot of material.
W: Well, I’m sure your presentation will go really well.
M: Thank you.

Conversation 2
M: Hello, Jane. I’d like to talk to you about a research project that you might be interested in. A friend of mine is working in Yellow Stone National Park this summer.
W: A research project in Yellow Stone?
M: Yes, she is working with the buffalo population. Their heads have been increasing in size lately which is good in theory.
W: Yeah, but I thought they were in danger of becoming extinct.
M: Well, apparently because of all the winter tourists, paths are created in the snow. (5) More buffaloes are surviving the harsh winters because the paths make it easier for the buffaloes to move around and find food.
W: But I heard some of the herds are infected with bacteria. Is that true?
M: Yes, it’s true. And because the buffalo population is increasing, the disease begins to spread to the cattle ranches that border the park.
W: That’s bad news. Isn’t it?
M: Yes. And it caused a lot of controversy. Some of the ranches even want to destroy the buffalo heads.
W: That’s awful. Have they made much progress with the research?
M: (7) So far they have been collecting tissue samples from dead buffaloes to see if bacteria is present.
W: (7) I’d really be interested in working on this. (6) You know I’ve been researching diseased animal population.
M: (6) That’s why I thought of you. I took the liberty of mentioning your name to my friend. She hopes you can spend the whole summer out there.
W: Well, I was going to work on my thesis a lot in July, (7) but I’m sure my advisor wouldn’t want me to pass up this opportunity.
