based on my understanding, I changed it a bit.
After three weeks, firefighters could finally have this blast forest fire in control. Not long ago, this land was still covered by old tall trees miles around, but now smoke coming from hot land surface, stretches across the lifeless hill. Winter is coming, hills deadly threatens to villages, because heaven rain will not only flush soil away, but will also cause mud flood. Just after fire was put off, Forest Management Bureau ordered tons of fast grow grass seed. These seeds were spread to this land by air planes. It will start rain in one month, by then, grass will be rooted in many places, and eventually, grasses will emerge on this tarred land as replacement of these old trees that had been there for centuries.
消防队员们同那场森林大火搏斗了将近3个星期才最后把火势控制住。就在不久之前，参天大树还覆盖着方圆数英里的土地。而现在，发热的地面上仍然升腾着烟 雾，弥漫在荒凉的山丘上。冬季即将来临，这些山丘对周围的村庄具有毁灭性的威胁，因为大雨不仅会冲走土壤，而且还会引起严重的水灾。在大火最后被扑灭后， 森林管理当局订购了好几吨一种生长迅速的特殊类型的草籽。飞机把这种草籽大量地撒播在地上。飞机撒播近一个月后，开始下起雨来。然而到那时，很多地方的草 已经生了根。一片片的绿草开始出现在这片烧焦的土地上，代替了多少世纪以来一直生长在那里的参天大树。
