Everyone is forgetful, but as we age, we start to feel like our brains are slowing down a bit—and that can be a very annoying thing.Read on for some techniques worth trying.
⒈
People who regularly made plans and looked forward to upcoming events had a 50 percent reduced chance of Alzheimer's disease (早老性痴呆症), according to a recent study.Something as simple as setting a goal to have a weekly coffee date with a friend will do. There's evidence that people who have a purpose in life or who are working on long or short-term goals appear to do better. In other words, keep your brain looking forward.
⒉ Go for a walk
Mildly raised glucose (葡萄糖) levels can harm the area of the brain that helps you form memories and physical activity can help get blood glucose down to normal levels. In fact, exercise produces chemicals that are good for your brain.
⒊ Learn something new
Take a Spanish class online, join a drawing club, or learn to play cards. A study found that mental stimulation (刺激) limits the weakening effects of aging on memory and the mind. But the best thing for your brain is when you learn something new and are physically active at the same time.or go dancing with your friends.
A. Focus on the future.
B. This can be especially harmful to the aged.
C. It should be something like learning gardening.
D. So take a few minutes each day to do some reading.
E. But don't worry if your schedule isn't filled with life-changing events.
F. Luckily, research shows there is a lot you can do to avoid those moments.
G. In other words, when you take care of your body, you take care of your brain.
【答案】F；A；E；G；C
【解析】本文主要介绍了几种方法来让你的大脑保持敏捷灵活。
(1)考查上下文的语境理解能力。空前一句的意思是：每个人都很健忘，但是随着我们慢慢变老，我们开始感觉大脑好像很迟缓了，并且这样的情况很让人心烦？空后一句的意思是：看看下面这些值得一试的建议吧。所以选F，这是一个过渡句，承上启下（幸运的是，研究表明你可以做很多事来预防这样的时刻。）承上启下，与前后一致，所以答案是F。
(2)考查上下文的语境理解能力。根据本段的叙述我们可以看出，这里是在说有目标，向未来看的人对于预防老年痴呆是很有好处的。再结合本段的最后一句话“In other words, keep your brain looking forward” 可知，这里是在建议我们向前看。聚焦未来，与文意相符，所以答案是A。
(3)考查上下文的语境理解能力。空前提到研究表明有计划可以降低一般得老年痴呆症的几率，空后提到：一些类似于和朋友约每周喝咖啡这样的小事儿就可以。所以选E项（如果你的计划里没有改变生活的事情也别担心。）与后文的叙述一致。所以答案是E。
(4)考查上下文的语境理解能力。空前提到，身体锻炼能够产生对大脑好的化学物质。G项（换句话说，当你照顾身体的时候，你就是在照顾你的大脑。）前后意思一致。所以答案是G。
(5)考查上下文的语境理解能力。根据本段的中心内容，和空前提到：对于大脑最好的就是你学一些新的东西并且同时身体保持活跃。空后提到：和朋友学习园艺。可知，C项（可以是想跳舞这样的事情。）与前后文意思一致。所以答案是C。
