近年来,全国性的、世界性的大型天灾都有多发、频发态势。除了地震、火山喷发、泥石流、森林大火,听了之后觉得是偶发事件之外,至于旱灾、水灾、风灾、沙灾以及北极冰层的破裂和消融等等,都近于司空见惯。若是包括人祸,如矿难、空难、车祸以及某些国家的战祸、匪祸等等,也是接二连三,层出不穷。 In recent years, there have been numerous and frequent large-scale natural disasters nationwide and worldwide. Except for earthquakes, volcanic eruptions, mudslides and forest fires which, after listening to them, are considered sporadic events, the drought, floods, windstorms, sandstorms and the Arctic ice sheet rupture and ablation are all commonplace. Including man-made disasters, such as mining disaster, crash, car accident and the war in some countries, banditry, etc., but also one after another, one after another.
