2020年职称英语理工类B级完形填空(1) Avalanche and Its SafetyAn avalanche is a sudden and rapid flow of snow, often mixed with air and water, down a mountainside. Avalanches are among the biggest dangers in the mountains for both life and property.All avalanches are caused by an over-burden of material, typically snowpack, that is too massive and unstable for the slope that supports it. Determining the critical load, the amount of over-burden which is likely to cause an avalanche, is a complex task involving the evaluation of a number of factors.Terrain slopes flatter than 25 degrees or steeper than 60 degrees typically have a low risk of avalanche. Snow does not gather significantly on steep slopes; also, snow does not flow easily on flat slopes. Human-triggered avalanches have the greatest incidence when the snow's angle of rest is between 35 and 45 degrees; the critical angle, the angle at which the human incidence of avalanches is greatest, is 38 degrees. The rule of thumb is： A slope that is flat enough to hold snow but steep enough to ski has the potential to generate an avalanche, regardless of the angle. Additionally, avalanche risk increases with use; that is, the more a slope is disturbed by skiers, the more likely it is that an avalanche will occur.Due to the complexity of the subject, winter travellingin the backcountry is never 100% safe. Good avalanche safety is a continuous process, including route selection andexamination of the snowpack, weather conditions, and human factors. Several well-known good habits can also reduce the risk. If local authorities issue avalanche risk reports, they should be considered and all warnings should be paidattention to. Never follow in the tracks of others withoutyour own evaluations; snow conditions are almost certain to have changed since they were made. Observe the terrain andnote obvious avalanche paths where plants are missing or damaged. Avoid traveling below others who might trigger an avalanche.雪崩和安全问题雪崩是雪掺杂着空气和水沿着山体突然迅猛地滑动造成的。
