You must think a computer is the best thing in the world, right? You must think it works at a super speed and can do everything? Well, it’s not! In fact, the brain is much more powerful than any super computer! Think about when a glass is just about to fall off the table. Your brain controls everything that you need to do to save that glass from falling. First your eyes check out what’s going on, then tell your brain, and your brain decides how quickly you need to react(反应), and then your muscles(肌肉) go into action. That is just from your brain. No computer could ever come close to that!
The brain weighs just 3 pounds, but it controls everything you do from thinking, learning, feeling even to breathing and your heart beating. Even though the brain is just 2% of your body weight, it uses around 20% of all your energy in your body. That is a lot for such a small organ(器官). There are about 100 billion tiny, tiny little cells(细胞) in your brain. There are so many that it would take you over 3,000 years to count them all!
Your brain stops growing when you’re 18, but it actually keeps on developing and learning new things. So your parents are really super smart! You won’t be able to fool them! Believe it or not, your brain NEVER stops working. Even during sleeping, the brain works for long-term memory establishment(建立). It is realized that the brain is the second organ in the body as the heart that never stops during human lives.
So everyone should be proud of such a gift of nature.

Money makes the world go around, yet the best thing in life is free. A penny saved is a penny earned（赚）, but you get what you pay for. You probably have your own ideas about spending money. Now is a great time to learn how to spend money wisely.
When you are considering buying something you want, run through this checklist first.
* How much do you really want it?
Seeing a $25（172 yuan） gum ball（口香糖球） machine, Ben wanted it. But after thinking about it, he felt it would interest him only for a day or two. “Besides, it’s not possible for me to chew（咀嚼） that much gum,” he said wisely.
* 71______
If the thing passes the “really-wanting-it” test, try to wait for some time to see how strong the desire（欲望） is. This strategy works for grown-ups, too!
* 72____
After the first two steps, Ben found he really wanted a toy pirate ship（海盗船）, but it cost $50. He had $22 in his pocket and gets $1.50 a week to spend. His mother helped him work out how many weeks he would need to save to get the ship: 19.
* 73____________
Ben agreed to wash the downstairs windows at a dollar each. So he got $10—and sparkling（闪亮的） sunlight for the rest of the family.
* 74____________
After deciding to buy it, it is necessary for you to look for less expensive ways to buy it: search for what you want on the Internet or in shops and flea markets（跳蚤市场）. Sometimes you can find the same thing at a much lower price.
If these suggestions work well, they can save you a lot of money. You will be a really smart shopper.
