As it is, the sloth mainly eats leaves because they tend not to run away.(就像这样树懒基本只吃树叶因为树叶大都不会逃跑。)
Because sloth bears are smaller than brown and polar bears and are under greater threat from dangerous animals, they may have adopted the extra precaution of carrying their cubs.(因为树懒的体型比棕熊和北极熊要小，而且面临着更大的来自危险动物的威胁，所以它们可能会带着幼仔采取额外的预防措施。)
Is that asword? Luxury! Is that a horse? Sloth! Is that ahelmet? Vanity !(那是剑吗？是奢侈！那是马吗？是懒惰！那是头盔吗？是虚荣！)
In an unusual display of sloth caution on my part, however, I held back out of prudence.(然而，在一个对我来说非同寻常的对懒惰警戒的展示中，出于谨慎，我忍住了。)
That's one suave sloth!(这是一只文雅的树懒！)
He admitted a lack of motivation and a feeling of sloth.(他承认自己缺乏动力，感觉懒散。)
All things are difficult to sloth.(勤则万事易，懒则万事难。)
Until lately, you led a life of innocent sloth.(直到最近，你过的还都是不问世事的懒散生活。)
