    There are many things you can do to improve your memory. Among them are different memorizing methods

as well as taking special care of your health.

    It is important that you regularly stimulate (刺激) your brain to make your memory more efficient. You can

do this by doing activities that you don't normally do and by changing your daily habits. Learning a new skill

helps your brain to develop. When trying to memorize something, you should not allow other thoughts to entre

your mind because this will reduce your chances of making right memories.

    An excellent way to help memory is to connect information with pictures. It is called memonics (记忆术).

Try to see the pictures in your mind. Taking notes, being organized and keeping a diary will also be useful ways. 

    Healthy food and plenty of vitamins are good for your memory to work properly. Drinking a lot of water also

helps to keep your memory. You must allow your brain to have enough sleep and a good rest. When you are

asleep, your brain stores memory. Not enough sleep can cause problems with the storing information and being

tired will stop you from being able to concentrate(集中) well. Caffeine in tea and coffee is very good at

preventing sleepiness and helping concentrate well, 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 well-not just for improving your memory.
