Easy Ways to Keep Your Brain Sharp
Everyone is forgetful, but as we age(變老), we start to feel like our brains are slowing down a bit—and that can be a very annoying thing.   小題1:  Read on for some techniques worth trying.
1.   小題2: 
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.   小題3:  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.   小題4: 
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.   小題5:  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.

小題1:F
小題2:A
小題3:E
小題4:G
小題5:C

 小題1:
Examinations are almost always stressful. Students rarely know exactly what to expect on the test, and those who suffer from exam fear or exam anxiety can see their grades suffer as a result of this stress. For some students，exam fear causes them to “ seize up ’’ and forget what they have studied.
   小題2:   Good study habits and learning how to relax can help students overcome exam fear.
    小題3:    According to Penn State University and Kids Health，proper study habits and preparation are the keys to cutting out exam fear. Avoid last-minute “cramming” for exams and actively listen while in class.
Focus on positive thoughts, relax the night before your test and reward yourself after the test is over. Often, people who suffer from exam anxiety cannot shut out negative thoughts or emotions about the test, and this can contribute to feeling more anxiety than normal.    小題4:    . Keep your mind and body healthy by getting enough sleep, eating well and exercising. Healthier people who are well-rested often do better on exams.
    小題5:  Exam fear is normal When that anxiety severely interferes (干擾)with your ability to take the test, however, outside help might be needed. Ask your teachers and family for support and help.
A．How To Succeed in An Exam
B．How To Overcome Exam Fear
