Question 25 is based on the passage you have just heard.

    Thanks to the International Space Station, we know quite a bit about the effects of low gravity on the human body, (22) [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.

    The scientists first sent 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’ll notice in the video, (23) [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. (24) [The 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.

    The scientists wanted to see whether the mice would continue doing the same kinds of activities they were observed doing on Earth. (25) [The study showed that the mice kept much of their routines intact, including cleaning themselves and eating when hungry.] 

25. What did the scientists find about the mice from the experiment?

解析：B。录音最后说到，科学家想看看这些老鼠是否会继续保持它们在地球上时固有的那些行为习惯。研究表明，老鼠的日常活动基本没变，包括自己理毛以及在饥饿的时候进食。由此可知，老鼠的表现和在地球上并无二致，故正确答案为B。

错项排除：录音最后提到老鼠的日常活动基本没变，但这说的是老鼠在太空的活动和在地球上一样，并不是每天重复一样的活动，A项中repeated一词没有依据，故排除。录音最后还提到老鼠在饥饿时会进食（eating when hungry），并没有提到它们进食减少，故C项排除。录音中明确说到，老鼠还是继续保持（kept）着它们的日常活动，并没有发生什么变化，故D项错误。
