sloth GREGMAT

The sloth spends most of its time hanging upside down from the branches.

大部分时间里树都是挂在树枝上。

Absence of competition makes for sloth.

没有竞争会导致惰。

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.

在辽阔草原的边缘，有一对貌似马儿的有蹄草食动物、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。
