    Reasons to exercise regularly     You've been told a hundred times that exercise is good for your health.  ____12____Here are four benefits that you can get from just a little daily exercise.   ___13___  DO you feel a bit clearer after good daily exercise? Not only is your brain getting more energy and oxygen, but many studies have shown that exercise can help you remember and learn things better. Of course, an intense exercise right before a big exam could leave you more tired than smart - but the two are still undoubtedly linked.     You'll become more confident.    ___14___ Through exercising, you will feel more accomplished and social (if you work out at a gym). Even if you don't see immediate results in your body, the effort will make you feel better - and a bit of confidence can go a long way.     You'll live longer. It's no secret that healthy living will keep you alive longer. One study found that exercise improves life expectancy as much as quitting smoking.  ____15____And just a bit of regular exercise can slow the process for a while.     You'll sleep better. If you ever have trouble falling asleep at night, it is a good way to solve this problem with regular exercise. The National Sleep Foundation says that regular exercise can help you sleep better. ____16____ If you exercise too closely to bedtime, it can actually have the opposite effect! Luckily, you can choose other good ways to fill up that pre-bed relaxation time. A. You'll be happier. B. It is really true that sitting all day is killing you. C. You'll improve your memory. D. Both of these are important parts of losing weight. E. Obviously, exercise can improve your appearance which can improve confidence. F. It's true, and it's good for a lot more than just losing weight or building muscle. G. The best time to exercise is in the morning or in the afternoon, rather than before bed. 答案：FCEBG
