The new findings hold that less demanding activities, such as listening to classical music, probably won’t bring noticeable benefits to an aging mind.“It seems it is not enough just to get out and do something—it 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 skill—digital photography, quilting, or both—which 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 skills—we 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?

B.Completing word puzzles alone.

B.Participants will continue the research for 5 years.

4.Which of the following can be the best title of this passage?

B.outdoor activities result in aging cognitive vitality
C.high-quality life calls for new learning skills
D.a new study finds how to keep a healthy mind
If you're finding it tough to land a job, try expanding your job-hunting plan to include the following tactics：
Set your target. 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 interviews—answering 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 for—or any other position—is open. Do this with every position you interview for，and you may just catch a break.
Make it your full-time job. You can’t find a job by looking sporadically（时有时无地）. You have to make time for it. If you’re unemployed and looking，devote as much time as you would to a full-time job. If you have a job while you’re looking，figure out an organized schedule to maximize your searching time.
Network vertically（垂直地）. In the research phase of your job hunt，talk to people who are on a level above you in your desired industry. They’ll have some insights that people at your own level won’t have，and will be in a good position to hire you or recommend you to be hired. Keep your spirits up. Looking for a job is one of the toughest things you will ever have to do.
Maintain your confidence，stay persistent，and think positively，and eventually you will get a job that suits you.
5. What is the advantage of setting your target?
A.It will help you prepare your interview.
B.It will keep your options open to compromise.
C.It makes the interviewers think highly of you.
D.It will make your job-seeking more efficient.
6.What is the author trying to tell you in the fourth paragraph?
A.A thank-you letter may suggest you are polite to the interviewers.
B.You may get a chance if you take some measures after failing an interview.
C.Taking note is very important when having an interview.
D.The interviewer will give you a job after they receive your second letter.
7.The underlined word “haphazard” in the second paragraph is closest in meaning to .
A.random
B.considerate
C.professional
D.scientific
8.Who is this article most probably written to?
A.A job-hunting adviser.
B.A job seeker.
C.A job trainer.
D.A job interviewer.

答案
Ⅰ.阅读理解
A
语篇导读：最近人们发现老年人外出休闲并不能让他们远离老年痴呆症，只有要求较高的智力挑战才能激发他们的认知活力，从而让他们的大脑更为敏锐。
1.【解析】细节理解题。由第一段的内容可知，要求不高的智力活动对老年人的大脑没有多大的好处，反之，要求高的智力活动会大有裨益，故不断学习新技能可以改善老年人的大脑；又由第七段可知，数码摄影技术对老年人来说是一种新的技术，故选D项。
【答案】D
2.【解析】推理判断题。由第四段中的内容可知，我们应该学会如何保持健康的头脑，但我们对此却了解得非常少，对老年人的大脑了解得就更少了。由此可推断，我们应当更多地关注老年人大脑，故选C项。
【答案】C
3.【解析】细节理解题。由文章的最后一段可知，研究者们将跟进研究一到五年，故实验参与者们也要继续五年的时间，故选B项。
【答案】B
4.【解析】主旨大意题。纵观全文，作者介绍了最近的新发现——要求较高的智力挑战有助于激发老年人的认知活力，从而让他们的大脑受益，故选A项。
【答案】A
B
语篇导读：这是一篇说明文，从几个方面，教你怎么找工作。
5. 【解析】细节理解题。根据第二段“you should also be sure to target exactly what you want in a job. A specific job hunt will be more efficient”可知,设定具体的目标有助于提高找工作的效率。
【答案】D
6.【解析】推理判断题。第四段讲述即使面试失败了，先写一封感谢信。几周后再写一封信说明你依然没有找到好工作，并且如果你之前应聘的岗位或其他的岗位有空缺的话，你还可以再次面试。如果你对每一个你所面试的岗位都这样做的话，你可能会有好运气。故选B项。
【答案】B
7.【解析】词义猜测题。从这一段可以看出haphazard在这里的意思应是“随意的，无计划的”。
【答案】A
8.【解析】推理判断题。这篇文章是教你如何找工作的。这样的文章最可能写给找工作的人。A项为工作顾问；B项为找工作的人；C项为工作培训师；D项为面试官。
【答案】B
