The enemy of memory is forgetting. To i mprov e memory is to avoid and overcome forgetting as much as possible. In learning activities, as long as we practice consciously and master the rules and methods of memory, we can improve memory. Here are 10 ways to enhance memory: 1. Stay focused. When we memorize something , as long as we concentrate and get rid of all the interference, t here will be deep memory traces on the cerebral cortex ( 大脑皮层 ) and they are not easy to be forget ton . On the contrary , it will greatly reduce the efficiency of memory. 2. Have great interest. If we have no interest in learning materials, even if we spend much time, it is difficult for us to remember them. 3. Memorize after u nderstanding . Understanding is the basis of memory. Only what we understand can be remembered for a long time. It ’ s not easy to remember by rote (死记硬背) . For the important learning materials , if we can combine understanding with recitation, the effect of memory will be better. 4. Over study. If you have to memorize a material 5 times, you need to memorize it at least 8-10 times. That way, you will really learn the material by heart. 5. Review in time. F orgetting is fast first and then slow. R eview and consolidate just-learned knowledge in time is an effective way of strengthen ing the memory trace and prevent ing forgetting . 6. R ecall constantly . When learning , try to recall constantly . It can correct mistakes in memory, make up for omissions, and help us remember difficult points better. In our spare time, if we often recall what we have memorized in the past, it can also help us avoid forgetting. 7. Have an a udio-visual combination . We can strengthen memory and improve memory efficiency by using the functions of language, v isual and auditory organs at the same time. It is much better than only silent reading. 8. Use m ultiple means . According to the situation, we can flexibly use various kinds of memory methods, such as classified memory, chart memory, shortened memory, m ak ing an outline, taking notes, cards and so on, which can enhance memory. 9. Make full use of the best time. Generally speaking, the best time is 9-11 a.m., 3-4 p.m. and 7-10 p.m. In the above time, i t is better to memorize the learning materials which are hard to remember. 10. Use the brain in a scientific way. Scientific use of the brain can greatly improve the working efficiency of the brain on the basis of ensuring nutrition, active rest, physical exercise and other maintenance of the brain. This is the key to improving memory. (437)
