2020年12月英语四级听力真题答案短文三篇(新东方版)

　　Passage 3

　　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. ㉒To that end, they have been studying how other species deal with low gravity, specifically focusing on mice.

　　The results are both interesting and humorous. The scientists first send some mice and especially designed cage to the International Space Station. The cage allowed them to study the behavior of the mice remotely from earth via video. ㉓As you'll notice in the video, the mice definitely seem uncomfortable at 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 use the lack of gravity to their advantage as they push themselves around the cage. That's when things really get wild.

　　㉔The 11th day of 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. ㉕The 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 the routines intact, including cleaning themselves and eating when hungry.
