Sometimes we may forget something easily. Don't worry. If you want to have a good memory, please follow me.
My first advice is that if you want to remember something well, you have to review it regularly (有规律地). After you learn the material, you need to review it right away, then two days later, then a week later, then two weeks later, and then a month later.
My second advice is to mark the important parts of your book. This will help you in two ways. On the one hand, it will help you concentrate on (专注于) the most important parts. It is always easier to remember only the key points. When you open your book, the colored parts will show you the most important parts at once. In this way, you needn't read every word again.
One good time for memorizing information is in the evening. Review what you have learnt before going to bed. It will be kept in your mind deeply. The other good time is in the morning because you have just rested and your brain is fresh and clear.
Remember all the advice above, and your memory will be better and better.
A. On the other hand, this will make reviewing easier.
B. Here is some advice to help improve your memory.
C. Another piece of advice is to review at a proper time.
D. You have to read the whole book from the beginning to the end.
E. So it's easy to memorize the important information in the morning.
F. After a month, you will find that you can remember the material easily.
