Passage Two

听力原文

    (12) A good dose of willpower is often necessary to see any task through, whether it’s sticking to a spending plan or finishing a great novel. (13) And if you want to increase that willpower, a new study suggests, you just simply have to believe you have it. According to the study, what matters most is what we think about our willpower. If we believe it’s a finite resource, we act that way. We feel exhausted and need breaks between demanding mental tasks. However, people who view their willpower as a limitless resource get energized instead. The researchers used a psychological assessment tool to test the validity of the study. They asked 1,100 Americans and 1,600 Europeans to grade different statements such as “after a challenging mental activity, my energy is depleted and I must rest to get it refueled again” or “I can focus on a mental task for long periods without feeling tired”. Although there was little difference between men and women overall, Americans were more likely to admit to needing breaks after completing mentally challenging tasks. (14) European participants, on the other hand, claimed they were able to keep going. Based on the findings, the researchers suggest that the key to boosting your willpower is to believe that you have an abundant supply of it. (15) Your feelings about your willpower affect the way you behave. But these feelings are changeable, they said. Changing your beliefs about the nature of your self-control can have positive effects on character development. This leads to healthier behaviors and perceptions of other people.

14. What do we learn about European participants as compared with their American counterparts?

解析：A。原文说到，美国人在完成智力挑战后更可能承认需要休息，而欧洲人可以继续坚持，即继续工作，A项中的keep on working longer对应原文中的keep going，因此本题选A。
