Does Fame Drive You Crazy?
Although being famous might sound like a dream come true, today's star, feeling like zoo animals, face pressures that few of us can imagine. They are at the center of much of the world's attention. Paparazzi (狗仔队) camp outside their homes, cameras ready. Tabloids (小报) publish thrilling stories about their personal lives. Just imagine not being able to do anything without being photographed or interrupted for a signature.
According to psychologist Christina Villareal, celebrities - famous people - worry constantly about their public appearance. Eventually, they start to lose track of who they really are, seeing themselves the way their fans imagine them, not as the people they were before everyone knew their names. "Over time," Villareal says, "they feel separated and alone."
The phenomenon of tracking celebrities has been around for ages. In the 4th century B.C., painters followed
Alexander the Great into battle, hoping to picture his victories for his admirers. When Charles Dickens visited America in the 19th century, his sold-out readings attracted thousands of fans, leading him to complain (抱怨) about his lack of privacy. Tabloids of the 1920s and 1930s ran articles about film-stars in much the same way that modern tabloids and websites do.
Being a public figure today, however, is a lot more difficult than it used to be. Superstars cannot move about without worrying about photographers with modern cameras. When they say something silly or do something ridiculous, there is always the Internet to spread the news in minutes and keep their "story" alive forever.
If fame is so troublesome, why aren't all celebrities running away from it? The answer is there are still ways to deal with it. Some stars stay calm by surrounding themselves with trusted friends and family or by escaping to remote places away from big cities. They focus not on how famous they are but on what they love to do or whatever made them famous in the first place.
Sometimes a few celebrities can get a little justice. Still, even stars who enjoy full justice often complain about how hard their lives are. They are tired of being famous already.

TaIL Spin
Two dolphins race around in a big pool in the Ocean Park. The smaller dolphin Grace, shown off a few of her tricks, turning around and waving hello to the crowd. The most amazing thing about her, however, is that she’s even swimming at all. She doesn’t have a tail.
Grace lost her tail as a baby when she got caught up in a fish trap. When the dolphin arrived at the Ocean Park in December 2005, she was fighting for her life. “Is she going to make it?” Her trainer, Abbey Stone, feared the worst. Grace did make it --- but her tail didn’t. She ended up losing her flukes and the lower part of her peduncle.
Over the past six years, she has learned to swim without her tail. Dolphins swim by moving their flukes and peduncle up and down. Grace taught herself to move another way---like a fish! She pushed herself forward through the water by moving her peduncles from side to side.
The movement put harmful pressure on Grace’s backbone. So a company offered to create a man-made tail for her. The tail had to be strong enough to stay on Grace as she swam but soft enough that it wouldn’t hurt her.
The first time Grace wore the artificial tail. She soon shook it off and let it sink in the bottom of the pool. Now, she is still learning to use the tail. Some days she wears it for an hour at a time, others not at all. “The tail isn’t
necessary for her to feel comfortable,” says Stone, “but it helps to keep that range of motion(动作) and build muscles(肌肉).”
Now, the dolphin is about to get an even happier ending. This month, Grace will star in Dolphin Tale, a film that focus on her rescue and recovery.

The oldest and most common source(来源) of renewaBle energy known to man, Biomass is one of the most important forms energy production in the United States and elsewhere. Since such a wide variety of Biomass materials is everywhere ---- from trees and grasses to agricultural and city ---- life wastes ----Biomass promises to play a continuing role in providing power and heat for millions of people around the world.
According to the Union of Concerned Scientists(UCS), Biomass is a kind of renewaBle energy source that produces no carBon dioxide(二氧化碳), Because the energy it contains comes from the sun. When plant matter is Burned, it gives off the sun's energy. In this way, Biomass serves as a sort of natural Battery(电池) for storing the sun's energy. As long as Biomass is produced continuously ----with only as much grown as is used--- the "Battery" lasts forever.
According to the Energy Information Administration, Biomass has Been one of the leading renewaBle energy sources in the United States for several years running through 2007, making up Between 0.5 and 0.9 percent of the nation's total electricity supply. In 2008----although the numBers aren't all in yet----wind power proBaBly took over first place Because of the rapid development of wind farms across the country.
Producing power from Biomass helps reduce some 11 million tons of carBon dioxide each year. Some homeowners also try to make their own heat By using Biomass materials. Such practice may save homeowner's money, But it also produces a lot of pollution. So, the Best way is to encourage power plants to use it.
