M: 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 a forty-mile crack, some 30 feet wide in places has torn through the ice shelf. W: I understand that the scientific community is quite concerned. What is the significance of these events？ M: 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 green house effect. W: But couldn't crumbling ice shelves also be a result of the unusual weather Antarctica itself has experienced lately？ M: That's certainly possible, but you'll have to remember that over the past thousands of years, ice shelves have been through a lot of weather changes without breaking up. W: I think most people know that if the ice cap over Antarctica melts, the level of the oceans will rise. What sort of impact will this have？ M: Well, the ice shelves currently insulate the Antarctic continent from wind, which slows down the melting. If the winds cause even a tenth of the continent's ice to melt, the world's oceans could rise as much as 30 feet. What are the speakers mainly discussing？ A．An experiment in Antarctica. B．Part of the Larsen Ice Shelf broke off. C．The formation of the Larsen Ice Shelf. D．An expedition in Antarctica.

science, but I would say that there are not 5 percent of the people who are equipped of schooling, including college, to S2.______ understand scientific reasoning. We are more ignorant of science as people with comparable education in Western Europe. S3.______ There are a lot of kids who know everything about computers—how to build them, how to take them apart, and how to write programs for games. So if you ask them to explain the principles of physics S4.______ that have gone into creating the computer, you don't have S5.______ the faintest idea. The failure to understand science leads to such things like the neglect of human creative power. It al- S6.______ so takes rise to blurring of the distinction between science S7.______ and technology. Lots of people don't distinguish from the two. S8.______ Science is the production of new knowledge that can be applied or not, and technology is the application of knowledge to the production of some products, machinery or the like. The two are really very different, and people who have the faculty for one very seldom have a faculty for another. S9.______ Science in itself is harmless, more or less. But as soon as it can provide technology, it is net necessarily S10.______ harmful. No society has yet learned to forecast the consequences of new technology, which can be enormous. 【S1】
