Question 22
A、How mice imitate human behavior in space.
B、How low gravity affects the human body.
C、How mice interact in a new environment.
D、How animals deal with lack of gravity.
听前预测：快速浏览本部分各题的所有选项,根据 in space、 lack of gravity、low- gravity environment、on Earth等可大致推断该听力文章与地球和太空活动相关。此外,根据 mice imitate、 human behavior、 the changed environment、 felt at home、 in the new environment、 repeated their activities和changed their routines等可推断内容很可能涉及人类活动、老鼠、地球以及环境改变等内容。听录音时需特别注意相关信息、把握重点细节。
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.［22］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 hem 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 bwhen 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.
［25］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 the routines intact, including cleaning themselves and eating when hungry.
Question 22 What do NASA scientists want to learn about? 讲话中提到，为此，他们一直在研究其他物种是如何应对低重力环境的，特别是在老鼠身上。因此，科学家们想了解的是其他物种在低重力环境中的应对方式，尤其是在老鼠身上，选项D中的 lack of gravity是对 low gravity的同义复述，且老鼠也是一种动物，所以，选项D为正确答案。其余三项讲话中并未提及，故均可排除。
