Question 20 is based on the passage you have just heard.

听力原文

      “One 60-minute run can add 7 hours to your life.” This was a claim made by The Times last week. The claim was based on a new review of studies about the effects of running. (19) [The review concluded that on average, runners live 3 years longer than non-runners, and that running does more to extend life than any other form of exercise.] But there’s more to running than its health benefits. (20) [Research published in recent years has shown that running changes your brain and mind in some fascinating ways, from increasing your brain function to regulating your emotions.]

        However, the precise effects vary according to whether you engage in short, fast running or long distance running. For example, in one study, researchers compared participants’ ability to learn new words after several minutes of intense running and after 40 minutes of gentle running. Participants were able to learn 20% faster after the intense running, and they showed a superior memory when tested again a week later. (21) [In another study, researchers asked volunteers to jog for 30 minutes and then show them clips from a sad movie.] Participants who usually struggled to handle negative emotions were more intensely affected by the sad clips, just as you expect. (21) [But crucially, this was less so if they had completed the 30-minutes jog.] The researchers said moderate exercise appears to have helped those participants to be less vulnerable to the impact of the sad movie.

20. What is one effect that running has on people according to recent research?

解析：A。录音中提到，近年来发表的研究（Research published in recent years）表明，跑步以一些神奇的方式改变你的大脑和思维，从提高你的大脑功能到调节你的情绪。A项Improving their brain function是对录音中changes your brain and mind和from increasing your brain function to regulating your emotions的概括，故为正确答案。

错项排除：B项利用录音中出现的regulating进行干扰，但录音中是说调节情绪，B项的breathing rate在录音中无依据，故排除。录音中虽然提到跑步可以延长人的寿命（extend life），但这并不等于延缓衰老，C项语义理解偏差，故排除。D项利用常识进行干扰，但这不是最新研究的结果，故错误。
