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、An experiment in Antarctica.
B、The breaking off of the Larsen Ice Shelf.
C、The formation of the Larsen Ice Shelf.
D、An expedition to Antarctica.
答案
B
解析
主旨题。对话开头处男士请女士介绍一下拉森冰架(Larsen Ice Shelf)的破裂情况,随后二人就这一问题展开了讨论,由此可知,对话主要是围绕拉森冰架的破裂展开的,故答案为[B]。
