小学生10分钟应用题系列答案There are many things you can do to improve your memory(记忆力). 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（习惯）. 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 not
es and keeping a diary will also be helpful.
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.
