懒人注目！再光吃不动就变"熊猫人"哦！

 　　The lifestyle that we see in pandas is quite enviable to many of us as all they do is eat and laze around in places. So basically all they do is eat and relax all day long.

　　我们当中的许多人对于熊猫的生活方式非常羡慕，它们基本上一整天啥也不干，除了吃，就是玩！

　　They once had been hardcore carnivores but their ancestors made a gradual switch to an all-bamboo diet which started somewhere between 7 million to 2 million years ago. Meat is dense¹ in energy and a little of it goes a long way whereas bamboo just cannot be considered as a nutritious² diet as they are locked-up in a cellulose which is very difficult to digest.

　　熊猫曾经是铁杆的食肉动物，但大约七百万到两百万年前，它们的祖先逐渐开始只吃竹子。肉可以提供很多能量，吃一点点就可以很抗饿，而竹子却不被当作是营养丰富的食物，因为它们的纤维素很难消化。

　　A little more has been known of the panda lifestyle by a new study published in the journal Science about the “Exceptionally low daily expenditure³ in the bamboo-eating giant panda”. The giant pandas actually have a digestive system designed for a carnivore and yet their food habits are herbivorous. And for herbivores, one would expect a more active lifestyle, but these cuddly⁴ pandas are immeasurably lazy.

　　《科学》杂志发表了的一项新的名为《吃竹子的大熊猫日常消耗极低》的研究，使得我们对熊猫的生活方式多了一点点了解。实际上大熊猫的消化系统是食肉动物，但它们的饮食习惯是食草。说到食草动物，人们觉得它们的生活方式更活泼，但是这些可爱的熊猫却超级懒惰。

　　懒人注目！再光吃不动就变熊猫人哦！

　　A team of scientists from China along with another one from Scotland have thoroughly⁵ analyzed⁶ the hourly behavior of 3 wild and 5 captive pandas.Researchers found out that a 200 lbs panda needs less than half energy than a human with the same weight. All the while to fulfill⁷ nutrient⁸ needs, pandas eat heaping quantities of bamboo, anywhere from 20 lbs to 40 lbs per day. They don’t, actually more likely they can’t get much energy from their diet and they also have significantly low metabolism⁹.

　　来自中国的一个科学家小组和另一个来自苏格兰的科学家小组详细分析了3只野生和5只圈养大熊猫每小时的行为。研究人员发现，一个200磅的熊猫和一个同等的重量人相比，消耗的能量只有一半。同时为了满足营养需求，熊猫要吃大量的竹子，每天20磅到40磅不等。它们很可能实际上并不能从它们日常饮食中获取很多的能量，其新陈代谢也非常的低。

　　This is makes is very evident that pandas spend a majority of their time lounging around. They actually have been physically¹⁰ active half of their time in the wild whereas in captivity¹¹, they have only been one-third of that. Their purpose of moving around is to obtain food, but other than that, they do not carry out much physical tasks.

　　这就是为什么熊猫把大部分时间都在躺着。熊猫在野外时一半时间是活络的，而圈起来后，它们的锻炼时间只有三分之一。它们四处走动的目的是获取食物，但除此之外，它们不进行任何的体育锻炼。

　　Humans these days are no different than modern-day pandas. Back in the days our ancestors worked hard to maintain their lifestyles, our present lifestyle are very dependent on technology and machineries so we barely need to move around too much. The same applies for pandas, they have settled for bamboos that are quickly available for them and make them less energetic so they just roll around in grass while surviving on that diet. Humans have much bigger brains so they naturally consume a lot of energy and their upright bodies are made for locomotion¹² and biologically they require a much richer diet of a wide range of nutrients¹³ from various sources, unlike woody grasses that bamboos are.

　　今天的人类和现代的熊猫没有什么不同。在过去，我们的祖先努力保持其生活方式，而我们现在的生活方式非常依赖技术和机器，所以我们不太需要动。熊猫也一样,以现成的竹子为生，使得它们精力不那么旺盛,它们只需要在草地上打滚，就可以生存下来。人类的大脑更大，所以自然会消耗大量的能量，直立的身体就是为了运动，在生理上需要更丰富的饮食和更为多样的营养来源,而不是竹子这样的木本草本植物。

　　There are numerous evidences supporting how essential it is to move around and how sitting around is detrimental¹⁴ to health. Pandas are adapted to sitting around and they actually cannot move around more than they already do. Humans on the other hand, have a choice.

　　许多证据表明，运动何其重要、久坐伤害健康。大熊猫适应了坐着不动，而且它们实际上已经不太能运动了。而另一方面,人类是可以选择的。
