Thanks to the International Space Station we know quite a bit about the effects of low gravity on the human body, but NASA scientists want to learn more. To that end, they have been studying how other species deal with low gravity, specifically focusing on mice. The results are both interesting and humorous.
多虧了國際空間站，我們對低重力對人體的影響有了一些了解，但美國宇航局的科學家們還想了解更多。為此，他們一直在研究其他物種如何應對低重力，尤其是老鼠。結果既有趣又搞笑。
The scientists first send some mice in a specially designed cage to the International Space Station. The cage allowed them to study the behavior of the mice remotely from Earth via video. As you noticed in the video, the mice definitely seem uncomfortableat the beginning of the experiment. They move around clumsily, drifting within the small confines of the cage and do their best to figure out which way is up, but without success. However, it's not long before the mice begin to catch on. They adapt remarkably well to their new environment and even using the lack of gravity to their advantage as they push themselves around the cage.
科學家們首先把一些老鼠放在一個特別設計的籠子里送到國際空間站。在這個籠子里，他們可以通過視頻從地球上遠程研究老鼠的行為。正如你在視頻中注意到的，在實驗開始的時候老鼠看起來肯定很不舒服。它們笨拙地四處走動，在籠子的小范圍內漂移，盡力想知道哪個方向是向上的，但都沒有成功。然而，沒過多久老鼠們就開始喜歡上了。它們能很好地適應新環境，甚至利用失重的優勢在籠子里推來推去。
That's when things really get wild. The 11th dayof the experiment shows the mice are not just dealing with the gravity change but actually seem to be enjoying it. Several of the mice are observed running around the cage walls.
事情到了真正瘋狂的時候。實驗的第11天表明，老鼠不僅能應對重力變化，而且似乎還樂在其中。有幾只老鼠被觀察到繞著籠子的墻壁跑。
The scientists wanted to see whether the mice would continue doing the same kinds of activities they were observed doing on Earth. The study showed that the mice kept much of their routines intact, including cleaning themselves and eating when hungry.
科學家們想知道這些老鼠是否會繼續做他們在地球上觀察到的同樣的活動。研究表明，老鼠的日?；顒踊颈３譀]變，包括清潔自己以及饑餓時進食。
