17．It sounds an ad from late-night TV:Follow this four-step plan and improve your memory in just 14d——青夏教育精英家教网—

17．It sounds an ad from late-night TV：Follow this four-step plan and improve your memory in just 14days!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-3fats，whole grains and antioxidants．Eating frequent meals prevents dips in blood glucose，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 control，which can impair memory and has been found to shrink the memory centers in the brain．
Before-and-after brain scans showed the participants experienced on average a five percent decrease in brain metabolism in the dorsal lateral prefrontal region of the brain，which is directly linked to working memory and other cognitive functions．This suggests they were using their brains more efficiently．The subjects also performed better on a cognitive test．However，a control group that didn't follow the plan showed no significant changes．
"We've known for years that diet and exercise can help people maintain their physical health，which is a key component of healthy aging，"said Gary Small，professor of psychiatry and behavioral sciences UCLA．"But maintaining mental health is just as important．Now we have evidence which suggests that people can keep their memory by adding memory exercises and stress reduction．"

16．Children are our future，and it's up to us to arm them with the tools to succeed．Sadly，today's children are being armed with more dangerous tools like weapons，drugs and gangs（帮派）．Once a relatively peaceful environment，many schoolyards of today are becoming unsafe for both students and teachers．
Home schools are available to give you choices．Home schooling provides top-quality education，flexibility，and freedom to create your own schedule （日程表）．At Heritage Home School we believe the choice should be yours．
Thanks in part to modern technology，home schooling information is becoming readily available across our nation．A recent study by the ITBS（Iowa Tests of Basic Skills）and TAP（Tests of Achievement and Proficiency）shows us that students of home schools do particularly well when compared with the nationwide average．In every subject at every grade level，students of home schooling scored obviously higher than those in public and private schools．
If you're new to home schooling，you may be asking yourself，"Will home schools really work for my children？"
Fact：A nationwide study using a random（任意）selection of 1，516families found students of home schooling to be scoring，on average，at or above the 80th percentile in all areas on standardized achievement test．
Note：The national average on standardized achievement tests is the 50th percentile．
Collectively，the staff at Heritage Home School brings 65years of experience in home schooling curriculum．We've placed students in the top 2% of the nation in math and many are successfully moving on to college．
One study found that of the home schooled adults，2% were unemployed，2% were on welfare and 94% said home education prepared them to be independent persons．
