[EX Q]: Article: Myth: Skipping meals helps you lose weight fast. Truth: There's no truth in this advice. Not only will you lose weight by starving yourself, but according to Carol Ann Rinzler, this may actually cause you to gain weight. Rinzler reasons that missing a meal causes your metabolism to slow down so that you burn food more slowly. This only makes you feel hungrier and by the time you finally do reach the table you will probably eat more food. Strange as it may seem, studies show that eating several small meals and snacks throughout the day is a more healthy way to lose pounds. Myth: If you swallow gum ,it will stay inside your stomach for seven years. Truth: Actually, it takes just a few days for gum to make its exit---not seven years, says Nei Izenberg, M. D., editor of Kids Health Organization. But because gum is made of the same thing as rubber, it cannot be fully digested in your stomach--- so if you gum up the works on a regular basis, you might find yourself in a sticky situation. Myth: The best way to stop a nosebleed is to lift your head back. Truth: Now that's bad advice. Bloody noses are caused by broken blood vessels , so while lifting your head back might stop the fluid from rushing out of your nose, it won't stop the bleeding; you'll just end up swallowing lots of blood. Your best bet? "Rest quietly. Don't poke or pick, and the blood will naturally clot within a minute or two". Suggests Dr. Izenberg. Myth: Cutting your hair will make it grow long faster. Truth: That's not true. "Your hair isn't like a lawn or a rosebush, where cutting can stimulate fresh growth," says Phillip Kingsley. The length of your hair is genetically ( ) determined. When it reaches a certain length, it stops growing. When you clear up the dead split ends, this make your hair look healthier, but not necessarilylonger.

[EX Q]: Article: Why are we addicted to upgrades? According to Donald Norman, American author of the book The Design of Everyday Things, "planned obsolescence" is the trick behind the upgrading culture of today's consumer electronics industry. The New York Times cited Norman last month, saying that electronics manufactures strategically release new upgrades periodically, both for hardware and software, so that customers on every level feel the need to buy the newest version. "This is an old-time trick- they're not inventing anything new," he said. Thomas Wensma, a Dutch designer, despises the "planned obsolescence" of companies, as recently reported by UK-based The Guardian. Wensma said this is a wasteful system through which companies - many of them producing personal electronics - release shoddy products simply because "they know that, in six months or a year, they'll put out a new one". But the new psychology of consumers is part of this system, as Wensma said to the newspaper: "We now want something new, something pretty, the next shiny thing." _ "It's to the damage of the consumer and the environment," as the New York Times quoted Norman. "But perhaps to the betterment of the stockholder." In its most recent fiscal year, Apple's profit margin was more than 21 percent, reported the Los Angeles Times. At Hewlett-Packard, the world's biggest PC manufacturer, it was only 7 percent. "Steven Jobs pushed the principle of 'planned obsolescence' to new heights," the newspaper commented on the company's profits and marketing strategy. "Apple's annual upgrades of its products generate sales of millions of units as owners of one year's MacBook or iPhone line up to buy the newest version, even when the changes are incremental." Peer pressure As to Li Jijia, the need for upgrading his smart phone comes mainly from friends and classmates. When the majority of friends are switching to the latest devices, he worries about feeling left out. "Some apps and games require better hardware to run," said Li. "If you don't join in, you lose part of the connection to your friends."

[EX Q]: Article: We all use money every day. It is essential because we can pay money for whatever we want.Money is recognized as banknotes and coins. However,many years ago people couldn' t go to the shop and buy what they wanted.They had to get what they wanted through the barter trade .It was really difficult,for the barter often depended on coincidence of wants.For example,the seller of grain has to find a buyer who wants to buy grain and who also could offer something the seller wants to buy.And one more example,if a wheat farmer needs what a fruit farmer produces,a direct exchange is impossible because seasonal fruit would spoil before the grain harvest.The solution is to trade fruit for wheat indirectly through a third intermediate commodity ,such as cattle,salt,shells,wine.However,commodity money had their disadvantages.For example,cattle,fur,precious stones couldn' t be cut into smaller pieces and it was inconvenient to keep and transport them.Thus coins were invented. The earliest known coins in the western world came from Lydia in about 650 B.C.Greek cities,the Great Persian Empire and Roman Empire quickly adopted the new useful technique of metal currency.And by the end of the 6th century,coinages were common throughout the region.However,coins as well as commodity money had many disadvantages.For instance,coins quickly show wear and they usually have small value,so it' s difficult to count large sums of coins. At first,paper money was used in China in about 650 A.D.After then,it was used in Persia and Japan.In Europe,paper money was firstly produced in the Netherlands in the 16th century and in the USA in the 17th century.Paper money is worthless but symbolic.In other words,paper money is just a note.It has a purchasing power because the government announces it as money and citizens accept it universally.
