　　1，您觉得大熊猫吃屎吗?

　　当然不能，大熊猫多可爱啊

　　可能吧，一切皆有可能

　　应该吃，谁不呢

　　Student

　　In our reading assignment, we learned that because giant pandas still retain their carnivore-specific genes, they don’t obtain very much protein or energy from the bamboo they eat. If that’s true, how will they survive on such a diet?

　　Professor

　　That’s a really good point. Giant pandas actually digest the cellulose in bamboo using microbe bacteria in their gut. Pandas don’t produce these bacteria naturally, and instead get them from ingesting their mother’s feces. Even though they have acquired this unique adaptation, they have to constantly consume large quantities of bamboo. An average giant panda eats as much as 9 to 14 kilograms of bamboo shoots a day. They have this short and straight digestive tract that results in the plants passing rapidly through their body with very limited digestion. The low energy intake from eating bamboo is the reason why a giant panda is constantly eating and has little time for social interactions. It also means that they don’t digest most of what they eat and will defecate up to 40 times a day. There are other adaptations that help a giant panda survive. It has also a round face to accommodate the powerful jaw muscles that crush and grind the bamboo. Its large body is also an adaptation that allows it to maintain a low metabolic rate.

　　Giant panda：大熊猫

　　Carnivore：食肉动物

　　Bacteria：细菌

　　Feces：排泄物

　　Digestive tract：消化道

　　总结：大熊猫小的的时候，需要摄取大熊猫妈妈的排泄物中的细菌，这样才能帮助熊猫爸爸消化食物。原来，大熊猫才是一把屎一把屎含辛茹苦地养大的哦!

　　1，您觉得大熊猫跟狗熊是亲戚?还是浣熊是亲戚?还都不是?

　　大熊猫当然是狗熊是亲兄弟啦

　　大熊猫和浣熊都有萌萌哒的黑眼圈，一定是亲戚

　　大熊猫和狗是兄弟，因为它们都有共同习惯

　　Student

　　It seems like even with so many adaptations, the giant panda still resembles a bear or a raccoon.

　　Professor

　　Yes and no. And molecular studies utilizing DNA found that the giant panda is part of the Ursidae family. When the entire genome of a giant panda was sequenced in 2009 and compared with genomes of other animals, the closest resemblance was actually to that of a dog!

　　听力学科词汇补充：

　　raccoon：浣熊

　　Ursidae：熊科

　　总结：大熊猫其实和狗才是亲兄弟哈，DNA 真实高科技。TPO10讲座第一篇，也是探索Whale鲸鱼竟然来自陆地动物，但它的祖先是谁呢?赶紧去做题听出答案哈!
