[1]Do you remember the title of the last book you read? Are names sometimes just beyond your brain’s reach? While forgetfulness isn’t necessarily a sign that something’s wrong, it can be frustrating(令人沮丧的)．But simple methods can help to sharpen your memory．
[2]Challenge your habits. Sometimes a little bit of habit changing goes a long way. For example，use the ‘wrong’ hand to do an everyday task several times a day．If you usually brush your teeth with your right hand, use your left．The brain ‘knows’ whew you're using the wrong hand．It’s that confusion that stimulates new brain circuits，as the brain struggles to master a new task．
[3]Get involved in niusic．Listening to music can improve your ability to concentrate and help you to remember what you’ve learnt．Some types of music actually cause brain neurons(神经细胞)to fire more quickly．If you’re really looking forward to sharpening your memory, take up a musical instrument．Whatever the instrument，learning to p1ay will tune your brain’s ability to analyse and focus．
[41Go out of your way to stay mentally active．What really counts is not the amount of book learning you did at school or university, it’s how much you actively use your mind．For example，doing crossword puzzles，learning a second language or playing games can exercise your brain．
[5]       ．Make sure that you get enough of the B vitamins in your diet．They help to repair brain tissue，and turn food into mental energy．Eat fish 2 or 3 times a week．If you drink coffee，you’ll not only get a short-term boost in your ability to concentrate but also long-term benefits as well．Besides, the brain is 85％water, so if you don’t drink at least 8 large glasses of water a day，you could suffer from memory loss．
