How to Activate Brain Cells
Scientists used to think that your brain stopped growing new cells once you reached adulthood. Happily, current research shows that it isn't true! As you get older, you can continue to grow new brain cells.
Get regular aerobic (有氧的) exercise.
Research shows that regular aerobic exercise over a long period of time can better improve brain cells' growth than other forms of exercise. Add aerobic activities such as swimming, power walking, and jogging, to your regular routine. 1
Do stress-relieving activities.
Activities that reduce stress and give you a sense of well-being can encourage the growth of new brain cells. 2 You can do some yoga, read your favourite books, or listen to relaxing music.
3
Antioxidant-rich (富含抗氧化物的) foods can prevent damage to your current brain cells and promote the growth of new, healthy cells. Omega-3 fatty acids may also help improve your brain's health. Add plenty of brain-boosting foods to your diet, such as vegetable oil, nuts, green tea, blueberries and fatty fish.
Maintain an active social life.
4 It's also good for your brain. Socialising helps keep your brain cells active, preventing some of the loss of brain function. If you can't socialise in person, reach your friends over the phone or on social media.
Get plenty of good-quality sleep.
If you're an adult, try to get 7—9 hours of sleep each night. If you're a teen, aim for 8—10 hours. Your brain heals itself of the day's stresses while you sleep. 5 You can improve your sleep by going to bed and waking up at the same time every day.
A. Spending time with friends isn't just enjoyable.
B. Eat foods rich in substances that do good to brain cells.
C. Any kind of head injury may put you at risk of brain damage.
D. Try to do things that bring you pleasure and help you relax every day.
E. For example, you might aim for 30 minutes of jogging a day, 5 days a week.
F. Fortunately, there are treatments that can help you restore your brain's health.
G. It also processes information you picked up during the day, helping you to learn and preserve new memories.

D 空前“减轻压力和给你一种幸福感的活动可以促进新脑细胞的生长。”建议做能够减轻压力、带来幸福感的活动。D项“试着每天做一些能给你带来快乐和帮助你放松的事情。”承接上文。故选D。 3. B 本段提到一些促进大脑发育的食物。B项“吃富含对脑细胞有益的物质的食物”能够总结概括该段内容。故选B。本题是本段小标题 4. A 根据本段小标题以及空后“这对你的大脑也有好处”可知，本段建议保持积极的社交生活，由空后的“also”可知，空处说的应该也是社交生活的好处。故选A。 5. G 根据空前“在你睡觉的时候，你的大脑会自愈白天的压力。”可知，睡眠对大脑有好处。G项与之并列，进一步说明睡眠对大脑的好处。且G项中的“It”指的是睡眠。故选G。
