M:Hey Sue, I was wondering if you could fill me in on Monday’s class. I had to go to the dentist for an emergency and I missed Professor Smith’s lecture. What was it on?
W:It was pretty interesting. She talked about volcanoes, active volcanoes, under the uh, West Antarctic ice sheet.
M: There are active volcanoes under the ice?
W: Apparently so. She said they help protect the ice sheet and prevent melting. Flooding would be pretty bad if that ice melted-not only there but all over the world.
M:You lost me there. Volcanoes are hot. How can something hot prevent ice from melting?
W:Wait a minute. Let me check my notes yeah, here it is. Volcanic heat melts just enough ice to create a slippery surface on the bottom of the glacier. This water allows ice to flow out into the ocean, so the solid interior ice is protected from the ocean’s warmth. Does that make sense?
M:Sort of. You mean that because the ice is flowing out to the ocean, the warmer ocean water can’t flow in?
W: Exactly. And the ice that melts is constantly being replaced by snow. Professor Smith said if the ice sheet ever broke up and melted, the sea level would go up seven meters. Then we’d have those floods.
M:Is that really possible, or is it one of those exaggerations you hear all the time?
W: As far as I can understand, it is possible. Because of global warming. I mean, if the ocean got a lot warmer, that interior ice would be very likely to melt.
M:Thanks for telling me about the lecture. Sounds like I missed a pretty important class.
1. Why did the man ask the woman about the lecture?
2. What was the topic of the professor’s lecture?
3. What information confused the man?
4. According to the woman, what protects the interior ice from the warmth of the ocean?
选项
A、Melting ice
B、Snowfall.
C、Glaciers which serve as barriers.
D、Variations in temperature in Antarctica.
答案
A
解析
火山融化掉一部分冰,这些冰水使得冰漂向海洋,从而保护了冰川的内部不会被融化。也就是说,保护冰川内部不被融化的是被火山融化掉的那部分冰,因此选A。
