Virtual reality is no longer a concept of the future. 3-D technology can now change a desktop computer into an interactiveworld of adventure, fashion, fun and entertainment.

Using the Internet as an entry platform, the new technology is blurring the lines between the real and virtual worlds.

In contrast to a traditional two-dimensional（二维的）interface, the 3-D environment provides a very large and highly social world, enabling access to people and places that would be impossible in the real world.

Through the use of avatars（虚拟替身）, a virtual replica of yourself, or whoever you want to be, life can take on new dimensions in cyberspace.

Shopping online is not such a new world to most people, but the 3-D experience is completely different. Via avatars, shoppers can pick up, try on and test out products in virtual shopping centres. The avatar, set with real-life measurements, can try on a new pair of jeans, get a trendy haircut and see if certain accessories suit.

Avatars can also join with like-minded people as they travel, take on adventures and socialize.

From a businessman’s point of view, interactive 3-D experiences allow him to exactly judge consumer demand via instant feedback and requests.

Buying property and taking a holiday in the real world also presents great virtual opportunities. Before buying a home, renting an apartment or booking a hotel, you can walk through a digital version of the property, making sure that it meets all your needs.

For people short of time and money in the real world, virtual tourism allows adventures in a virtual dimension. A virtual tourist can step inside the Louvre, trek into the Sahara, or go bungee jumping in New Zealand.

“3-D technology will influence many aspects of human life in that we can entertain ourselves from similar cyber games and experience exciting 3-D tourism,” explained Martin Tong, marketing director of The 1st Virtual Business and professional creator of a vitual world.

“Our understanding of the virtual world is to give customers a strong interactive experience; it is not only a game, but also life itself,” he added.

The new way of traveling will not necessarily meet everyone's satisfaction. Dong Lifen, an engineer in China Unicom commented that while the virtual world gives the freedom of traveling to popular destinations, it is not the same as the real thing.

Controlling Anger

   Robyn Lee， a 15-year-old teenage girl who studies at York Community High School， US says she has four friends. But she also has 15 to 20 other friends she considers part of her regular social circle.

“It's like a bad thing to have only one， friend ，”explained Robyn. “If you have one friend， it means only one person likes you. That’s not cool，” she said.

For many years， experts studying teen friendships have known that teenagers prefer to travel in groups. In studies conducted in 1963 and in 1995， researchers found teen friendship groups averaged six people. In 2005， when teens were asked about how many friends they kept in touch with regularly， the average answer was 20.

The change to bigger -group friendships has advantages， such as increasing more connections and improving teens' self-pride by giving them a place to belong.

However， the change also has some disadvantages，say psychologists. “The meaning of friendship is becoming much more complicated，” said Bernardo Carducci， a professor of psychology at Indiana University Southeast.

MaryRose Moss， a 17-year-old in Chicago， knows how she could get more friends. She created a Facebook page when she was 14 and within months ， she had her group of 500 friends.

Text messaging has opened the door to many new connections， she says. “I'm friends with some people that I wouldn't be as close to if it weren't for technology，” said Moss. “It's so easy to send a text to somebody even if you don't know him very well. ”

Some psychologists wonder whether social-networking technology is affecting some skills children once got from making friends in the old-fashioned way.

“In the past， you argued， discussed and reached an agreement， but if somebody disagrees with you now， you can ‘defriend’ him with the click of keys，” said Carducci.

Marianne Boe， a social studies teacher in Chicago ， sees signs of changing friendships in the hallways. Ten years ago， she could easily know groups of girls who stayed friends through all four years of high school. “Today， it's harder，” Boe said.

   It is a familiar scene these days: employees taking newly laid-off co-workers out for a drink for comfort. But which side deserves more sympathy，the jobless or the still employed？On March 6，researchers at a conference at the University of Cambridge suggested it was the latter.

Brendan Burchell，a Cambridge sociologist，presented his analysis based on various surveys conducted across Europe. The data suggest that employed people who feel insecure in their jobs show similar levels of anxiety and depression as those who are unemployed. Although a newly jobless person's mental health may“bottom out”after about six months，and then may even begin to improve，the mental state of people who are continuously worried about losing their own job“just continues to get worse and worse”, Burchell says.

Psychologists support this theory by arguing that human beings feel more stressed during times of insecurity because they sense an immediate but invisible threat. Patients have been known to experience higher levels of anxiety, for example, while waiting for examination results than knowing what they are suffering from—even if the results are cancer. It's better to get the bad news and start doing something about it rather than wait with anxiety.  When the uncertainty continues, people stay in a nonstop“fight or flight”response, which leads to damaging stress.

But not every employee in insecure industries has such a discouraging view, Burchell says. In general, women get on better. While reporting higher levels of anxiety than men when directly questioned, women score lower in stress on the 12-item General Health Questionnaire, even when they have a job they feel insecure about losing.  As Burchell explains,“For women, most studies show that any job—it doesn't matter whether it is secure or insecure—gives psychological improvement over unemployment.”He supposes that the difference in men is that they tend to feel pressure not only to be employed, but also to be the primary breadwinners, and that more of a man's self-worth depends on his job.
