The human brain weighs about 1.4 kilograms, but it can hold much more information than most computers. However, there is another difference between humans and computers. Computers don’t forget information they are given, but humans often do. No one remembers everything, and luckily we don’t usually have to. But everyone can improve their memory if they want to. Here are some suggestions.
◆Try to use new information immediately. For example, if you meet someone who says “Hi! I’m Carlos,” don’t just say “Hello.” Repeat the person’s name. Say “_________”
◆Break a big number into smaller parts. For example, it’s hard to memorize（记忆）109244153. But if you break it into three parts--109/244/153—it becomes easier.
◆Write out what you need to remember over and over again. This will help you keep it in mind longer, especially for memorizing formulas（公式）or facts.
◆Always review information. If you bring what you’ve learned back to your mind, they become easier to remember. For example, before you go to sleep, it’s a good idea to review the new things you learned that day.
◆Discuss with a friend. It is always easier to remember things through discussions. You can have a discussion about what’s right and what’s wrong, and it will lead to the right answer.
◆Never tell yourself that you have a bad memory. You can always do something to help improve your memory. And everyone’s memory gets better if they use it often enough.All of the suggestions are helpful. If you follow them, you are certain to improve your memory.

On February 9^th, 2013, Sarah Darling was walking along the street when she met a homeless man named Billy Ray Harris. She reached into her change purse, emptied out all the coins she had and gave them to the homeless man. Neither of them realized that this small generous（慷慨的） act would change their lives. Sarah didn’t realize that she had given Billy not only all her change but also her diamond ring（钻戒） that she had put in her change purse earlier until the following morning. She and her husband, Bill Krejci, rushed to see if they could find Billy. The homeless man was not only in the same place, he also immediately returned the ring. The grateful couple paid him back for his honesty by emptying out their pockets of all the money they had.
Bill Krejci, a web designer, felt that he needed to do something more for this amazingly honest man. So on February 18^th, he set up a special page to raise money for him. In just four days, Billy received over $85,000 and there seems to be no end yet.

WARNING: Holding a cell phone against your ear or putting it in your pocket may be bad for your health.
This sentence is a warning that you’d better not put it close to you when a new phone is bought. Apple company, for example, doesn't want iPhones to come closer to you than 1.5 centimeters; Research In Motion, BlackBerry's producer, recommends 2.5 centimeters.
If cell phone use can cause health problems, the result will be very serious. Americans spend 2.26 trillion minutes chatting on cell phones every year, which brings $109 billion for the wireless businessmen.
Devra Davis, an epidemiologist(皮肤病专家) who has worked for the University of Pittsburgh, has published a book about mobile phone radiation（辐射）"Disconnect." Davis studies how often brain cancer happens during different age groups. She finds a big increase (增长) in brain cancer in the 20-to-29 age group and a drop for the older people.
Children are more easily hurt by radiation than grown-ups, Ms. Davis and other scientists point out. But no studies have yet been finished on cell phone radiation and children, she says.
Henry Lai, a research professor, began lab radiation studies in 1980 and found that mice exposed to(暴露在) radiofrequency（电波频率）radiation had destroyed DNA in their brains.
Ms. Davis recommends using wired earphones（有线耳机）or the phone's speaker. Children should send text messages rather than call, she said, and pregnant women should keep phones away from their bodies.
