W: I see you are having the fish for lunch.
M: That’s right. Fish sticks and tomato soup, my favorites.
W: I bet they were frozen.
M: What?
W: The fish sticks.
M: Of course they were frozen. We are hundreds of miles from the ocean. The cafeteria can’t afford to fly in fresh fish.
W: I just mentioned it because Professor Chambers told us an anecdote in class this morning.
M: Which class?
W: My American social history. It’s a lot of fun.
M: He talked about fish sticks?
W: Not exactly. But he did talk about frozen fish. OK, this is back in 1920, right? It’s 20 degrees below zero. And this guy Clarence Birdseye’s out ice-fishing.
M: Where is this, Antarctica?
W: No. Massachusetts I think Anyway he catches a fish and drops it beside him on the ice and it freezes solid
M: So?
W: So, later at home he thaws out the fish in a bucket of water and it’s alive. Of course Birdseye is amazed. But he eventually figures out that the fish froze so fast that no large ice crystals formed.
M: What do you mean?
W: Look, usually when a plant or animal cell freezes, large ice crystals form inside and eventually tear the cell walls. That’s what kills the frozen plant or animal. And also what changes the taste of something that’s been frozen. But if you freeze something quickly, only very small ice crystals form. So Birdseye invented the process of quick freezing food.
M: And that was the beginning of the frozen foods?
W: Right.
5. Where does the conversation most probably take place?
6. Why does the woman tell the man the story?
7. Why is it important to quick freeze fresh food?
8. What was Clarence Birdseye surprised to find?

答案
