Directions: Read the following passage. Fill in the numbered blankets by using the information from the passage. Write NO MORE THAN THREE WORDS for each answer.
Like our body, our memory needs regular exercise to be in good condition. Like the sportsman who must train to allow the body to respond to difficult times, the memory needs its own special training in order to stay in “shape” and improve.
There are many factors that can cause poor memory like insomnia (失眠), depression and alcohol. However, there are simple ways which you can follow to keep your memory in shape and actually help you to improve your memory’s condition and performance.
Never stop learning. Look for topics that interest you and really get involved in learning new information about them. Reading and attending lectures or programs are sources of continuous education of your brain with beneficial results to your memory.
Develop your social and family relationships. The more social you are, the better it is for your brain. Studies have shown that the brain and heart have a lot to gain from good family and social relationships.
Exercise your mind with games. The more you use your brain, the more you help your memory stay in shape. There are many games that can make you an intelligent person as well as entertain you such as chess, puzzles and board games.
Exercise physically can improve your memory. This type of exercise improves the circulatory （血液循環(huán)的） system. Even the simple but regular daily exercise such as fast walking can improve the heart and oxygenation（供氧） of the brain. The benefits of exercise affect positively many body systems, as well as our memory and other cognitive（認知的） capabilities.
Eat more fruit and vegetables. What we eat every day affects the performance and long-term condition of our memory. Fruit and vegetables are an excellent source of antioxidants（抗氧化劑） and vitamins that can help and benefit the nervous system.
So our memory is like a sportsman. The more we practice our brains and memory, the better their performance will be.
