到乌蒙山区的昭通;从甘肃中部的定西,到内蒙古边陲的阿尔山,看真贫、知真贫,真扶贫、扶真贫,成为“花的精力最多”的事;“扶贫先扶志”“扶贫必扶智”“实施精准扶贫”Unit 5 The power of nature.阅读理解The new findings hold that less demanding activities, such as listening to classical music, probably wont bring noticeable benefits to an aging mind.“It seems it is not enough just to get out and do somethingit is important to get out and do something that is unfamiliar and mentally challenging, and that provides broad stimulation(刺激)mentally and socially,” said lead researcher Denise Park of the University of Texas at Dallas.The new findings provide much-needed insight into the factors of everyday activities that contribute to cognitive vitality(认知活力) as we age.“We need, as a society, to learn how to maintain a healthy mind, just like we know how to maintain physical health with diet and exercise,” said Park, “We know so little right now.” “This is an assumption, but what if challenging mental activity slows the rate at which the brain ages? Every year that you save could be an added year of high-quality life and independence.” For their study, Park and colleagues randomly assigned 221 adults, aged 60 to 90, to engage in a particular type of activity for 15 hours a week over the course of three months.Some participants were assigned to learn a new skilldigital photography, quilting, or bothwhich required active engagement and tapped working memory, long-term memory and other high-level cognitive processes. Other participants were instructed to engage in more familiar activities at home, such as listening to classical music and completing word puzzles. And, to account for the possible influence of social contact, some participants were assigned to a social group that included social interactions, field trips, and entertainment.At the end of three months, Park and colleagues found that the adults who were productively engaged in learning new skills showed improvements in memory compared to those who engaged in social activities or non-demanding mental activities at home.The three learning groups were pushed very hard to keep learning more and mastering more tasks and skills. Only the groups that were faced with continuous mental challenge improved. “Our participants essentially agreed to be assigned randomly to different lifestyles for three months so that we could compare how different social and learning environments affected the mind,” said Park, “People built relationships and learned new skillswe hope these are gifts that keep on giving, and continue to be a source of engagement and stimulation even after they finished the study.”The researchers will follow up with the participants one year and five years down the road to see if the effects remain over the long term.1.According to Park, which of the following can improve an aging mind?

While you should always keep your options open to compromise, you should also be sure to target exactly what you want in a job. A specific job hunt will be more efficient than a haphazard one. Schedule ample interviews. Use every possible method to get interviewsanswering ads,using search firms,contacting companies directly,surfing the Web,and networking. Even if a job is not perfect for you,every interview can be approached as a positive experience. Follow up. Even if someone does not hire you,write them a thank-you note for the interview. Then,some weeks later,send another brief letter to explain that you still have not found the perfect position and that you will be available to interview again if the original position you applied foror any other positionis open. Do this with every position you interview for,and you may just catch a break. Make it your full-time job. You cant find a job by looking sporadically(时有时无地). You have to make time for it. If youre unemployed and looking,devote as much time as you would to a full-time job. If you hav
