8:C 细节题.根据文章第一段Due to climate change,Arctic ice is breaking up earlier in the spring,and its area is decreasing可知冰在不停地融化.9:B 推理题.根据文章第2段But as the ice has melted,the polar bears have been forced to spend more time on land.There,they have begun to frequen...
根据第一段第一句“Due to climate change, Arctic ice is breaking up earlier in the spring, and its area is decreasing.(因为气候变化,北极冰层在早春时节就开始破裂,面积也在减少。)”可知冰在不停地融化,时间越来越早。 A. 意思是它在冻结; B. 意思是它在扩张; C. 意思是它在硬化; D. 意思是它...
Due to climate change, Arctic(北极的)ice is breaking up earlier in the spring, and its area is decreasing.This is creating problems for polar bears that make their homes off northern Alaska and in Hudson Bay. Polar bears off Alaska normally hunt and raise their young on ice sheets(大冰原...
The article discusses the academic field of glacial archaeology, which involves observation of melting ice that is said to be disappearing due to climate change. Topics include the discovery of ancient tools and other artifacts, the use of artifacts to date migrations and land use, and forecasting...

The design process used computational fluid dynamics (CFD) numerical tools to describe the ice development and its interaction with the aerodynamic flow. In particular, the ice melting due to thermoelectrical system action was modeled with its downstream motion, illustrating how the melting particles ...
