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.

   After years of research and tests, the hybrid car was developed and put on the market. It's an interesting and exciting new improvement in today's world as we look for better ways to protect the quality of the air we breathe and protect our natural resources.

The quality of our air is affected by many different things. But one of the largest sources of air pollution is the burning of fossil fuel such as coal and gasoline which is used to power a car's engine. The Environmental Protection Agency（EPA）has set national standards to help control the level of harmful pollutants sent off into the air, and the automobile industry has acted by producing the hybrid car that uses less gas and therefore causes less pollution.

A hybrid car is a combination of a regular car that runs on gasoline and an electric car that is battery-powered. Some people tend to think that since the hybrid car is partially electric, you have to plug it in to charge it. But that's not how it works. The 144 volt battery pack（电池组）is actually recharged through the energy that is produced when the car's brakes are used. This is referred to as "regenerative braking", because it generates electricity.

Although the hybrid car still runs on gasoline most of the time, this helps it use less gas than a regular car. When the driver stops at a traffic light, the engine automatically shuts off to save fuel. Then, as soon as the driver puts the car in gear and touches the gas pedal（踏板）, the engine starts backing up.

Have you ever ridden in a car with someone which ran out of gas？That probably wouldn't happen if you were riding in a hybrid car. It flashes a warning on its computer screen that says, "I am low on gas. "When it completely runs out, the warning reads, "YOU ARENOW OUT OF GAS！"Then the electric power supply starts to work to let the driver travel a few more miles to a gas station.

   Technology has enabled people to connect fast and across vast distances. 【小题1】 Therefore, it is important to find ways to communicate better, while we are still keeping pace with the demands of the modern day.

Cut back on texting. Texting is a good way of keeping in touch and communicating with another person if calling him is not possible. Unless you can’t help it, give up the habit of texting — while walking, eating or driving — because texting is not real communication. 【小题2】 Calling is a great way of enhancing conversations because it’s more direct, with a greater chance of successful communication.

【小题3】 We are more willing to spend time on Facebook than actually leave our desks and have a conversation with the person working right next to us. A good way of improving real-life communication is to log off or keep yourself away from social media.

Meet people face-to-face. The next time you want to open Facebook to chat with a friend, call him up and meet him instead. 【小题4】 Take time to meet the person who matters to you and you will get a kind of communication and relationship that staring at a screen just can’t provide.

Technology is a tool. It is worth remembering that technology is only a tool we have. 【小题5】Use social networks to find people, to reconnect with friends, to support a cause and to contribute to the bigger picture in a more real manner.
