问题  
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?

选项 A、Because she wants to inform him about the history class he missed.
B、Because the fish sticks he is eating reminds her of it.
C、Because she wants to tutor him in bio-chemistry.
D、Because she wants to encourage him to eat healthier food.

答案B

解析 一读选项,问题便一目了然:问原因。女士在对话开头说道:“我看到你中午在吃鱼。”之后又说:“我提到这件事是因为Chambers教授在今天上午的课上讲了一件奇闻轶事。”B与之相符。长对话的开头之处往往就是考点所在。
