stimulate your brain to make your memory more efficient.You can do this by changing your daily habits.Learning a new skill helps your brain develop.When trying to memorize something,you should focus your attention and concentrate on the most important things about what you are trying to remember.Do not allow other thoughts to enter your mind because this will lower your chances of making accurate memories.How to improve your memoryAn excellent way to help memory is to link information with pictures.These are referred to as mnemonic techniques.Try to see the images in your mind.Taking notes,being organized and keeping a diary are also useful methods.Healthy food and plenty of vitamins are essential for your memory to work properly.Drinking a lot of water also helps maintain your memory.You must allow your brain to have enough sleep and rest.When you are asleep,your brain stores memory.Not enough sleep can,therefore,cause problems with storing information.In addition,being tired will stop you from concentrating.Caffeine in tea and coffee are very good at preventing sleepiness and helping concentration,but they can also cause problems with memory.In order to concentrate well,you must be relaxed.Generally keeping fit and regular health checks are both important as wellnot just for improving your memory.Making notes(2)Sometimes you can read something and show its meaning by drawing a diagram.Some scientists believe that there are three kinds of memory immediate,short-term and long-term.Immediate memory holds items of information coming into it from the five senses for less than a second.Then it either rejects them or passes them into short-term memory.Short-term memory can hold about seven items of information at one time(e.g.,telephone numbers).It holds them for about thirty seconds.Then they are rejected(i.e.,forgotten)or passed into long-term memory.Three types of memory返回返回Long-term memory can hold information for the whole of our lives.Some scientists believe that long-term memory can be divided into two types.One type remembers events,that is things that happen to us.The other remembers knowledge(e.g.,the names of countries or the meanings of words).
