1. Because it is extremely cold at very high altitudes, snow rarely melts. 因为海拔很高，天气非常寒冷，雪很少融化。
2. People in Ethiopian highlands have adapted to living at high altitudes. 埃塞俄比亚高地的人们已经适应了在高海拔地区生活。
3. In the troposphere, the air at higher altitudes is in general cooler than the air below it. 在对流层中，高海拔地区的空气通常比低海拔地区的空气冷。
4. For starters, cabin pressures at high altitudes are set at roughly what they would be if you lived at 5,000 to 8,000 feet above sea level. 对于初学者来说，高海拔地区的舱内压力大致被设定为住在海拔在5000到8000英尺高的地方会有的压力。
5. Wind velocity also increases with altitude and may cause serious stress for trees, as is made evident by the deformed shapes at high altitudes. 风速也随着海拔高度的增加而增加，可能给树木带来严重的压力，这从高海拔地区的变形就可以看出来。
