Avalanche and Its Safety
An avalanche is a sudden and rapid flow of snow, often mixed with air and water, down a mountainside. Avalanches are【C1】______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【C2】______supports it. Determining the critical load, the amount of over-burden which is【C3】______to cause an avalanche, 【C4】______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 【C5】______of avalanche. Snow does not【C6】______significantly on steep slopes; also, snow does not【C7】______easily on flat slopes. Human-triggered avalanches have the greatest incidence when the snow’s angle of rest is【C8】______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【C9】______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 【C10】______; 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 travelling in the backcountry is never 100% safe. Good avalanche safety is a continuous【C11】______, including route selection and examination of the snowpack, weather【C12】______, and human factors. Several well-known good habits can also 【C13】______the risk. If local authorities issue avalanche risk reports, they should be considered and all warnings should be paid 【C14】______to. Never follow in the tracks of others without your own evaluations; snow conditions are almost certain to have changed since they were made. Observe the terrain and note obvious avalanche paths where plants are 【C15】______or damaged. Avoid travelling below others who might trigger an avalanche.
【C11】
选项
A、journey
B、trip
C、fact
D、process
答案
D
解析
尽管选项A、B和D都能和continuous搭配,从全段的内容判断,只有process是最佳选择,因为该段描写的是如何防备雪崩以及如何做好安全措施等一系列问题。
