But the Internet also brings us troubles、
Internet use seems to cause a fall in psychological（心理的） health, according to research at Carnegie Mellon University、Even people who spent just a few hours a week on the Internet experienced more depression and loneliness than those who logged on less often， the twoyear study showed、And it wasn’t that people who were already feeling bad spent more time on the Internet, but that using the Net actually seemed to cause the bad feelings
Researchers are puzzling over the results， which were completely opposite to what they had expected、They expected that the Net would prove socially healthier than the television， since the

Net allows users to choose their information and to communicate with others、
The fact that Internet use reduces time used for family and friends may be the reason for the drop in health， researchers said、Faceless， bodiless“virtual”(虚拟的) communication may be less psychologically satisfying than actual conversations， and the relationships formed through it may not be so deep、Another possibility is that exposure to the wider world through the Net makes users less satisfied with their lives、
“But it’s important to remember this is not about the technology; it's about how it is used，” said one of the researchers、“It really points to the need for considering social factors(因素) when you design new inventions、\

Computer technology is still developing rapidly、The computer of the future will continue to increase in value and performance while decreasing in cost、It will become smaller,but faster and more powerful、
It is possible to make some guesses about what the future of the computer will look like，based upon the types of technologies that are being developed now、A lot of progress has already been made in some of these new technologies，but some are still in their earliest stages and may not be ready for use for years、Two of the most interesting areas of computing that are currently being developed are quantum computing（量子计算) and nanotechnology(纳米技术).
Quantum computing is one possibility for the future of the computer that could make computers run far faster than even the quickest computers do today、Quantum computers could be able to do what modern supercomputers are unable to do by using transistors that are able to take on many states at the same time、
Nanotechnology could also change the face of computing,by creating computers that could be very powerful,though they are tiny in size、These computers could be incorporated(并入） into everyday objects,including electrical appliances(电器),clothes and even the human body、We will be able to use computers in new and unimaginable ways、They will become a part of our lives rather than simply being a box that is used only for specific purposes,such as work、
