There are many things you can do to improve your memo­ry. Among them are many kinds of useful ways as well as taking special care of your health.
It is important that you make yourself excited to make your memory more active. You can do this by doing some new activi­ties and by changing your daily habits. Learning a new skill helps your brain(大脑)to develop. When trying to remember something, you should pay special attention to the most impor­tant things about it. Do not allow other thoughts to enter your mind because this will reduce your chances of making right memories.
An excellent way to help memory is to connect information with pictures. Try to see the pictures in your mind. Taking notes and keeping a diary will also be helpful.
Healthy food and plenty of vitamins are necessary for your memory to work well. Drinking a lot of water also helps keep 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 cause problems with storing information. And being tired will also stop you from being able to think clearly and well.
In order to keep your mind on your work ， you must be free from worry. Generally, keeping fit and normal health checks are both important as well — not just for improving your memory.
