听力原文：W: I've been reading about new healthy snack food. It's made from fish. Have you
M: No. I haven't. But I don't like fish very much anyway.
W: Don't worry, Although it's made primarily from fish, it actually doesn't have a fishy taste. In fact it can be flavored with tomato, cheese, or chocolate for instance.
M: Do you know how this snack food is made？ How could it not taste fishy？
W: First, the fish is cooked, then water and flour are added to make a paste.
M: It sounds awful．
W: Actually the paste is flavorless. The flavorings are added to give it some taste.
M: Well. it still sounds a little strange. But I suppose this product will at least be low calorie and high protein, like health food.
W: Yes, you could call it that.And it has a long shelf life, so it won't spoil quickly. It is also easy to digest and can be made from types of fish that usually aren't eaten or from high grade fish by-products.
M: Mh... Have you got any sample？ I might be willing to try cheese—flavored variety.
W: No. None of these seems to be available yet. As I understand it,this fish snack food probably won't be in the stores for another couple of years. So you have a while to get used to the whole idea
M: A couple of years？ It may just take me that long, but thanks for telling me about it.
