Be at your best!
What does your brain need to work well? Here are some things it needs.
Good food
Experts say that breakfast is much more important than any other meal. So don't miss breakfast — especially before an exam! But you need to eat a good breakfast — junk food won't work.
A regular supply energy
Your brain needs a regular supply of energy, so you need to eat carbohydrates. They're found in bread, rice, pasta and beans. They work more quickly than bread and rice, so they give you a short burst (爆发) of energy, but afterwards you feel more tired.
A continuous supply of oxygen (氧气)
Your brain needs oxygen, which it gets from exercise. You also need a good supply of iron because iron helps your blood to carry oxygen round your body.
Water
. Not getting enough water will stop your brain from working well. And remember, water isn't as expensive as sweet drinks!
.
Your brain needs several hours' sleep, so it can ‘update' itself, just like a computer. Experts say that when you study for a test or an exam, you should get some sleep as quickly as possible after you've finished studying. This helps you to remember what you've learnt.
A. A short break.
B. A good night's sleep.
C. It works best in the morning.
D. Exercise improves your memory too.
E. Water is much better than sweet drinks.
F. Your brain works better when you have eaten.
G. Chocolate, biscuits and sweets are not good for your brain.
