Most people hope to have a good memory to help them succeed in study, work and life. Do you know how to improve the memory? (1) ____
Research shows that a healthy lifestyle keeps our memory better. Eating food rich in vitamin B and vitamin E, like vegetables, helps you have a better memory. (2) ____ Proper exercise provides much needed O₂ for the brain. Running, riding a bike, swimming or even walking two or three times a week are helpful. And getting enough sleep is important. Only when your brain gets a good rest can it work well. (3) ____
What's more, going over what you have learned can make the memory last long. (4) ____ For example, you can divide the nine-digit telephone number 081-127-882 into three groups: first 081, then 127, and lastly 882.

In a word, if you make a few good lifestyle changes and try some memory skills, you can certainly improve your memory.
