1. 大熊猫有没有换毛期? Do giant pandas experience molting periods?
大熊猫有换毛期,成年和幼年熊猫都有换毛的情况。根据对圈养大熊猫的观察,最为明显的是1.5-2岁的亚成年时期,从背部以下可能全换。也有季节性换毛的情况,但不明显。 Yes, giant pandas do experience molting periods, occurring both in adult pandas and panda cubs. According to the observation of the captive giant pandas, it happens most obviously in the sub-adult period from ages of 1.5-2 years, and they may molt completely on their hindquarters. Seasonal molting also may happen but is not as obvious.
2. 大熊猫的智商水平有多高? What is the IQ level of a giant panda?
大熊猫是非常聪明的动物。但目前尚专门的大熊猫智商研究:因此,没办法评判它们的智商水平到底有多高。根据观察,有些特别聪明的大熊猫非常善于瑞摩人类的心思。科技人员在训练大熊猫时,甚至发现有的大熊猫为了获得 “奖励”(比如一个苹果),会提前把“动作” 都做到位(这些动作我们尚末告诉它,但它似乎己经知晓)。以至于科技人员都在感慨:“不是我们训练大熊猫,而是大熊猫在训练我们! Pandas are very intelligent creatures, however, there have been no specific studies on their IQ levels. Observationally, some clever pandas are very good at understanding cues and body language of humans when researchers conduct positive training. Researchers have found that some giant pandas hold desired action in place in advance of the researcher asking for them to do it, because as soon as they see the reward (such as an apple), they badly want to have it. Many researchers feel that they are not training giant pandas, but rather are the ones being trained!
很满意节目,给了我新的启发,国内看到的英文可能也很地道,也可以学习。再请教老师一下,“当心”的英文表达,网上搜索后感觉还是有点糊涂,谢谢
