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.

在原的边缘，有一对貌似马儿的有蹄食动物、一只很像羚羊的南方有蹄类和一只地獭正在静静觅食，没有注意到大祸即将临头。
