【答案】Dear Zhang Hua，
Memory is important to everyone in all ages.You asked me how to improve it.I have some suggestions for you.
First，we should have enough rest.Enough rest can make sure that your brain works well because when people sleep，their brain can also have a good relax，which can provide enough energy for people in the daytime.Second，you should keep thinking.As we know，you can exercise your brain while you are thinking.So the more you think，the cleverer you will be.Finally，eating some healthy food is a good way to improve your memory too.Remember to have more food such as radish，cabbage and spinach.
Do as what I have told you，I'm sure they can help you a lot in the improvement of your memory.
Yours，
Editor
