M: Doctor White,[22]we recently learned that a large piece of the Larsen Ice Shelf in Western Antarctica broke off in early January. Could you please tell us exactly what happened?
W: I’d be happy to. The piece that broke off was over a thousand square miles in area. More recently and quite alarming to scientists is that the forty-mile crack, some thirty feet wide in places has torn through the ice shelf.
M: I understand that the Scientific Community is quite concerned. What is the significance of these events?
W: Well, some scientists believe that this is a clear sign of global warming. Back in 1978, some American researchers predicted that Antarctica would show early signs of global warming due to the greenhouse effect.
M: But couldn’t crumbling ice shelves also be a result of the unusual weather Antarctica itself has experienced lately?
W: That’s certainly possible.[24]But you have to remember that over the past thousands of years, ice shelves have been through a lot of weather changes without breaking up. Remember too that although ice shelves float on the ocean, they are attached to the continent and can be as thick as a thousand feet.
M: I think most people know that if the ice cap over Antarctica melts, the level of the oceans will rise. What’s sort of impact will this have?
W: Well, the ice shelves currently insulate the Antarctic continent from wind, which slows down melting. But without ice shelves to cool the wind, it would be warmer than usual as it flows over Antarctica.[25]If the winds cause even a tenth of the continent’s ice to melt, the world’s oceans could rise as much as thirty feet.
22. What are the speakers mainly discussing?
23. What is the significance of ice cracking, according to some scientists?
24. Why doesn’t the woman believe that weather is responsible for the recent events?
25. What would ice melting probably result in, according to the woman?
选项
A、No melting has been observed in harsh weather.
B、The weather in Antarctica has always been comfortable.
C、Nothing unusual has happened in other parts of Antarctica.
D、The ice shelf has remained complete despite the weather changes.
答案
D
解析
推断题。男士提出疑问,认为冰架破裂是南极洲近来的异常天气所致,女士说有可能,接着通过转折指出几千年来冰架经历了许多气候变化(weather changes)但并没有破裂(without breaking up),由此可知她认为最近的冰架破裂并不是由天气原因造成的,[D]为原文的同义转述,故为答案。
