Easy Ways to Keep Your Brain Sharp
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．（71）Luckily，research shows there is a lot you can do to avoid those moments． Read on for some techniques worth trying．
1． （72）Focus on the future．．
People who regularly made plans and looked forward to upcoming events had a 50 percent
reduced chance of Alzheimer's disease （早老性癡呆癥），according to a recent study．（73）But don't worry if your schedule isn't filled with life-changing events．．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．
2．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．（74）In other words，when you take care of your body，you take care of your brain．．
3．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．（75）It should be something like learning gardening．Or go dancing with your friends．

75．C     考查句意理解和上下文．由上句But the bestthing for your brain is when you learn something new and are physically activeat the same time．可知對(duì)大腦最好的事情是你學(xué)新東西時(shí)，身體也要?jiǎng)�，即腦力勞動(dòng)和體力勞動(dòng)相結(jié)合的事，就像學(xué)習(xí)園藝以及和朋友跳舞這樣的事情．故選C．
