大祸

The smallest deflection of the missile could bring disaster.

导弹有极微小的偏斜也可能酿出大祸。

At the edge of a sprawling grassland, a pair of hoofed grazers resembling horses, an antelopelike notoungulate and a ground sloth feed quietly, oblivious to their impending doom.

辽阔草原的边缘，有对貌似马儿的有蹄草食、只很像羚羊的南方有蹄类和只地獭正觅食，没有注意到大祸即将临头。
