Directions: Read the following passage and the statements that follow. Choose the best answer for each statement from the three choices marked A, B and C.
It sounds like an infomercial from late-night TV: Follow this four-step plan and improve your memory in just 14 days!
But researchers have indeed found a way to improve memory function in older people. After a two-week study that involved brainteasers (脑筋急转弯), exercise and diet changes, study participants' memories worked more efficiently.
Here's the program:
Memory Training: brainteasers, crossword puzzles and memory exercises that emphasized verbal skills throughout the day.
Healthy Diet: Five meals daily included a balanced diet rich in omega-3 fats, whole grains and antioxidants (抗氧化剂). Eating frequent meals prevents dips in blood glucose (血糖), the primary energy source for the brain.
Physical Fitness: Brisk daily walks and stretching. Physical fitness has been found in other research to reduce the risk of Alzheimer's disease.
Stress Reduction: Stretching and relaxation exercises. Stress causes the body to release cortisol (皮质醇), which can impair memory and has been found to shrink the memory centers in the brain.
