语 篇 提 能.阅读理解Avalanches (雪崩) are one of those natural disasters that can cause great damage and only Mother Nature knows when and where theyre going to occur. Even with modern technology its still impossible to know exactly when or where one is going to occur. Mountain climbers are wise to be careful, as avalanches kill many of them each year.The physics of how and why an avalanche occurs is complex. There are times of higher probability. During the year, the transition from winter to spring will cause some snow and ice to melt, which may trigger avalanches. Also at daybreak there is a higher probability due to the temperature change.While climbers hike up slopes (斜坡), some distance between the climbers should be kept. If an avalanche occurs, then there will be fewer lives lost and a higher probability that someone will be able to seek help. Since an accident is more likely to happen when a top layer of snow is loose, avoid areas where heavy snow or rain has recently occurred.Try to choose areas that you are familiar with and stay in areas with rocks, bushes and trees. Trees and bushes allow snow to pile up and keep the layers stable (稳定的). If an avalanche occurs, trees will take the impact of the snow, so there is a better chance of being safe.Climbers must also pay attention to the degree of the slope. Avalanches wont occur on level ground and there is little snowfall on very steep areas. The greatest danger is in areas where the slope is between 25 and 40 degrees.Remember that, if you get stuck in an avalanche, there is no car hire available to take you to the nearest airport.1What do we know from the first paragraph?A.
