Passage 1

　　Related to the ‘use-it-or-lose-it law’ is the ‘keep-moving principle’. We learned about stagnation from nature. A river that stops moving gets smelly. The same thing happens to people who stop moving, either mentally or physically. Those who play contact sports know that the player who usually gets hurt the most is the one who is standing still. Of course, you’ll need some time to catch your breath every so often, but the essential massage is keep moving, extending and learning. Ships last a lot longer when they go to sea than when they stay in the harbor. The same is true for the airplanes. You don't preserve an airplane by keeping it on the ground, you preserve it by keeping it in service. We also get to live a long healthy life by staying in service. Longevity statistics reveal that the average person doesn't last very long after retirement. The more we’ll hear is don’t retire. If a fellow says “I’m 94 years old and I worked all my life”, we need to realize, that is how he got to be 94, by staying involved. George Bernard Shaw won a Nobel Prize when he was nearly 70. Benjamin Franklin produced some of his best writings at the age of 84, and Pablo Picasso put brush to canvas right through his eighties. Isn’t the issue how old we think we are? A bonus with the ‘keep-moving principle’ is that while we keep moving, we don’t have a chance to worry. Hence we avoid the dreaded paralyses by analysis.

　　Questions 9 to 11 are based on the passage you have just heard.

　　Q9. What does the speaker say about players of contact sports?

　　Q10. What do longevity statistics reveal about the average person?

　　Q11. What bonus does the keep moving principle bring us according to the speaker?

　　Passage 2

　　In 2014, one in sixteen Americans visited the hospital emergency room for home injuries. One of the main causes of these accidents? A wandering mind! By one estimate, people daydream through nearly half of their waking hours. Psychologists have recently focused on the tendency to think about something other than the task one is doing. For one experiment, researchers developed an app to analyze the relationship between daydreaming and happiness. They found that the average person’s mind wandered most frequently about 65% of the time during personal activities, such as brushing their teeth and combing their hair. Respondents’ minds tended to wander more when they felt upset rather than happy. They were more likely to wander toward pleasant topics than unpleasant ones. How do daydreams affect daydreamers? A wandering mind leaves us vulnerable when driving. In one study, researchers interview 955 people involved in traffic accidents, the majority of them reported having daydream just before the accident. Yet other research suggests that daydreaming has benefits. Researches have found that it gives us a chance to think about our goals and it also seems to increase creativity. In one experiment, 145 undergraduates completed four unusual uses tasks, each requiring them to list as many uses as possible for everyday object. After the first pair of tasks was completed, one group of participants was assigned an undemanding activity intended to cause their minds to wander. When all the participants proceeded to the second pair of tasks, the daydreamers performed 40% better than the others.

　　Q12: What does the passage say about people’s mind?

　　Q13: For what purpose did the researchers develop the new app?

　　Q14: How does daydreaming benefit people according to some researchers?

　　Q15: What was the finding of the experiment with 145 undergraduates?
