M: No. I haven't, but 1 don't like fish very much anyway. W: Not to 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: How can it not taste fishy？ Do you know how this snack food is made？ W: First the fish is minced and cooked and fermented. Then water and starch are added to make a dough. M: It sounds awful. W: Actually the dough is very bland al that point, so 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 a 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 ha made from types of fish that usually aren't eaten, or from high grade fish by-products, M: Mm, have you got any samples？ I might be willing to try the cheese-flavored variety. W: No, none of it 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'll have a while to get used to the whole idea. M: A couple of years, ah？ It may just take me that long. but thanks for telling me about it.

W: Yes, I saw it in the paper. From a 200-foot high building, wasn't it？ I gather the driver had just got out or he'd have been killed, wouldn't he？ M: Oh, yes. I saw the car; it was totally damaged. W: You usually park your car around there, don't you, Bill？ M: Yes, I left it in that very spot a couple of days ago, but yesterday it was parked up the road. W: You were lucky then, weren't you, Bill？ M: Out of luck, you mean! I'd be very pleased if my old ear were smashed to bits. I could claim from the insurance company then, couldn't I？ W: But you used to be so proud of your car, weren't you？ M: I used to be years ago, but now there are all sorts of repairs to be done, and I just haven't got enough spare cash to put it right. W: You can always sell it, can't you？ M: Few people are stupid enough to buy a car in that state, are they？ W: The man whose car was crushed yesterday was very annoyed about it. He'll be given a new car by the builders, though. M: Yes, but his car was a specially-built model that can't be replaced, and there was hardly anything wrong with it, was there？ W: Well, that's life!

W: Oh, please be serious! I suppose they will change shapes as well. If you want a big car to take all your friends camping, I suppose you'll just be able to snap your fingers and make it happen. Or if you want a sporty two-seater, you could just tell the car what you wanted, and it would do the rest. Is that how it will work？ M: No, I am serious. They have found a way to alter the surface of metals so that they can reflect different colors just by passing a small amount of electricity over them. W: Oh, I see. So anything that touches the outside of the car will get a shock. That sounds lovely. M: It's only a tiny amount of electricity. It wouldn't be enough to shock anybody. W: Well, it sounds pretty difficult to believe. M: Yes, it's quite amazing. The important thing you have to remember is that the color of an object is really just an illusion created by the way light bounces off its surface. Engineers have been able to produce a car that changes colors at the touch of a button by slightly rearranging the position of the particles on the surface of the metal. W: It sounds so amazing. But I guess it could be possible. M: It is possible today. The only problem is that it is very expensive. To produce a car with a surface that changed colors would cost almost twice as much as what a regular car costs. For that much money you could just by the car and have it repainted twenty times, so it's not very practical yet. W: Yes, but in other ways it could be more practical. If you took your car to be painted twenty times, it would use quite a bit of polluting chemicals, and it would take a long time. M: You're right there, but how many people really get their car repainted that many time？ W: Hmm, I suppose you're right, but I sure would love to have my car match my outfit every day. (26) A．She is impressed. B．She is doubtful. C．She is shocked. D．She is surprised.
