are turning into barren stretches of dust and rock. 变成了贫瘠干涸的尘土沙石
thin soils soon turn to dust and blow away. 稀薄的土层很快就会变成沙尘 被风吹走
Where there's no escape from sun, wind and dust. 没有什么能阻挡烈日 狂风与沙尘
freezes into tiny crystals called diamond dust. 会直接凝结成冰晶 俗称钻石尘
After six months of drought, grass replaces dust over great areas. 六个月的旱季过后 如茵的绿草再一次覆盖了尘嚣大地
Without rain, these plains can become dust bowls. 由于缺乏雨水 这里的草原变成了黄尘地带
and then head back to the dust for no apparent reason. 数小时后就绝尘而去
but the dust can be blown 5,000 metres up into the sky. 但是尘埃却能被吹上5000多米高的天空
and the biggest source of sand and dust in the entire world. 也是全世界最大的沙尘源
Finally, the stragglers emerge from the dust. 最后 掉队者终于从尘埃中走了出来
