You’ll probably never go to Mars or sing on the stage with the Rolling Stones. But if virtual reality (VR) ever lives up to its promise, you might be able to do all these things—and many more—without even leaving your home. Unlike real reality, virtual reality means simulating(模拟) bits of our world. Apart from games and entertainment, it’s long been used for training airlines pilots and doctors and for helping scientists to figure out complex problems such as the structure of protein molecules.. Then how does it work?
Close your eyes and think of virtual reality and you probably picture something like this: a man wearing a wrap-around headset and data gloves wired(用线连接) into a powerful workstation or supercomputer. What makes VR different from an ordinary computer experience is the nature of the input and output. Where an ordinary computer uses things like a keyboard, mouse, or speech recognition for input, VR uses sensors(传感器) that find out how your body is moving. And where a PC displays output on a screen, VR uses two screens (one for each eye), surround-sound speakers, and maybe some forms of touch and body feedback(反馈) as well.
VR has been generally used by scientists, doctors, dentists, engineers, architects, archaeologists, and the army for about the last 30 years. Difficult and dangerous jobs are hard to train for. How can you safely practice taking a trip to space, making a jump from an airplane, or carrying out a brain operation? All these things are obvious applications of virtual reality.
Like any technology, virtual reality has both good and bad points. Critics always warn that people may be addicted to alternative realities to the point of ignoring their real-world lives—but that criticism has been leveled at everything from radio and TV to computer games and the Internet. Like many technologies, VR takes little or nothing away from the real world: you don’t have to use it if you don’t want to.

The elephant was lying heavily on its side, fast asleep. A few dogs started barking at it. The elephant woke up in a terrible anger: it chased the dogs into the village where they ran for safety.
That didn't stop the elephant. It destroyed a dozen houses and injured several people. The villagers were scared and angry. Then someone suggested calling Parbati, the elephant princess.
Parbati Barua's father was a hunter of tigers and an elephant tamer. He taught Parbati to ride an elephant before she could even walk. He also taught her the dangerous art of the elephant round-up -- how to catch wild elephants.
Parbati hasn't always lived in the jungle. After a happy childhood hunting with her father, she was sent to boarding school in the city. But Parbati never got used to being there and many years later she went back to her old fife. "Life in the city is too dull. Catching elephants is an adventure and the excitement lasts for days after the chase," she says.
But Parbati doesn't catch elephants just for fun. "My work," she says, "is to rescue man from the elephants, and to keep the elephants safe from man." And this is exactly what Parbati has been doing for many years. Increasingly, the Indian elephant is angry: for many years, illegal hunters have attacked it and its home in the jungle has been reduced to small pieces of land. It is now fighting back. Whenever wild elephants enter a tea garden or a village, Parbati is called to guide the animals back to the jungle before they can kill.
The work of an elephant tamer also involves love and devotion. A good elephant tamer will spend hours a day singing love songs to a newly captured elephant. "Eventually they grow to love their tamers and never forget them. They are also more loyal than humans," she said, as she climbed up one of her elephants and sat on the giant, happy animal. An elephant princess indeed!
