Slow Movers: Fun Facts About Sloths拖延家：树懒趣闻

David Attenborough once said if he could be any animal， hewould be a sloth—because he would have a good life， with“nothingmuch to do”. Maybe he was talking about the fact that sloths are theslowest-moving mammals in the world. In fact， it will take you less timeto read this text than it takes a sloth to move a few meters.

大卫·爱登堡（世界自然纪录片之父）曾经说过，如果他能变成任何一种动物，他会变成一只树懒———因为这样他可就过上好日子了，那就是“无所事事”。也许他说的是树懒是世界上行动最慢的哺乳动物。事实上，你读这篇文章所花的时间比一只树懒移动几米所花的时间还要少。

Slow movers and eaters它们行动迟缓且进食慢

Sloths travel fewer than 40 meters a day， onaverage2. They move slowly because they mostly eatleaves3， which don’t give them enough energy tomove quickly. It could take them as long as 30 daysto digest4 one leaf！ But this doesn’t affect5 theirpower. Sloths are about three times stronger than theaverage human.

树懒平均每天行走不到40 米。它们行动缓慢，因为它们主要吃树叶，树叶不能给它们提供足够快速移动的能量。它们可能需要长达30 天的时间来消化一片叶子！但这并不影响它们强壮有力。树懒比普通人大约强壮三倍。

Tree hangers6它们是树枝挂件

Sloths spend up to 90% of their lives hanging upsidedown in trees—mostly sleeping. A sloth sleeps between 15and 20 hours each day. Sometimes they fall7， and that’sokay！ They can fall up to 30 meters without getting hurt8，and on average they fall out of trees about once a week.And if they fall in water， that’s okay， too. Sloths aregood swimmers， and they move faster in water than theydo in trees！

树懒一生中有近90%的时间都倒挂在树上———大部分时间都在睡觉。树懒每天要睡15到20个小时。有时它们会掉下来，但没关系！它们可以从30米的高空坠落而不受伤，而且平均每周大概会从树上掉下来一次。如果它们掉进水里，也没关系。树懒擅长游泳，它们在水中的移动速度比在树上更快！

Their fur9 is a home for others它们的皮毛是其他动物的家园

Many different insects10 live in a sloth’s fur. It’s good for them becauseit’s warm and sometimes wet， and sloths don’t move much.

许多不同的昆虫会住在树懒的皮毛中。它们的皮毛很适合生存，因为这里温暖且潮湿，而且树懒不怎么活动。
