Television is playing a very important part in our lives. But like other things, it has both advantages and disadvantages.
In the first place, television is not only a convenient, but a cheap source of entertainment. For a family of four, for example, it is more convenient as well as cheaper to sit comfortably at home, with unlimited entertainment available, than to go out in search of amusement elsewhere. All they have to do is press a button, and they can see shows of every kind, not to mention the latest political discussions and exciting football match. Some people, however, think this is just where the danger lies. The television viewer takes no initiative. He is completely passive and has everything without any effort on his part.
Television informs us about current events, the latest developments in science and politics, and offers an endless series of instructive and entertaining programs. It could be argued that the radio can also perform this service; but on television everything is much more vivid. Yet again there is a danger. We get addicted to it, so dependent on its moving pictures that it begins to dominate our lives.
There are many other arguments. The poor quality of programs is often criticized. But it is a great comfort to many lonely people indeed. I think we must realize that television in itself is neither good nor bad. It is the uses to which it is put that determine its value to society.

With the development of science and technology, people depend more and more heavily on the computer. Then how does the computer affect our life?
On the one hand, it can be very helpful to people who need it and treat it corTectly. The computer can broaden our knowledge about the world. It can also help us learn more about many fields of studies quickly: science, medicine, arts and so on. It is very convenient to people who are busy with their jobs, and has brought about many positive changes in our lives.
On the other hand, the computer may bring about some negative changes. For example, many children become so addicted to computer games that they stay up late frequently and even neglect their studles. Another disadvantage is that computer's radiation is harmful to people's eyes, especially to children's.
Just as every coin has two sides, the computer has advantages and disadvantages. I think that if we can overcome its negative effects, we can bring it into full play.

Wireless phones are connecting the developing world at a rate of about one million new phones each day. And with them come important new uses for the technology.
Some of the ideas are being developed by a company in Washington, D.C. Paul Meyer is one of three people who started Voxiva, V-O-X-I-V-A, in two thousand one. They began with a simple question, he says. How can technology help countries deal with health problems or other issues?
Some leading social investors including the Acumen Fund helped launch Voxiva. The World Bank, the United States government and others helped the company expand.
Voxiva has been working with the government of Rwanda for about three years. The company created an information technology system for health workers to collect and share information about HIV/AIDS.
All health centers in Rwanda that provide care for HIV/AIDS report into the system every week. They can use different forms of technology, including the Internet, to connect to the system. But Paul Meyer says most of the centers use mobile phones. They report numbers of new patients and the treatments provided. They also report on the supplies of drugs available at each center.
The system cuts dependence on paper-driven communication. It gives health officials the ability to make decisions based on real-time information. In other words, the information is from right now, not weeks or months ago. With the system, health centers around the country can also receive information without any delay.
Paul Meyer says the Rwandan government spent about one million dollars to have the TRACnet system developed and put into place. TRACnet has since been expanded to other parts of Rwanda’s health care system.
Rural health centers in the Amazon Basin of Peru have been using a Voxiva system for more than five years. They use it to report cases of cholera, measles and other diseases. Indonesia is using Voxiva technology to follow cases of bird flu.
Disease surveillance systems have also been deployed in Andhra Pradesh and Tamil Nadu, India.
Paul Meyer says the technology is basic enough to have many uses. In some Peruvian cities, for example, citizens use Voxiva technology to report crimes and to interact with local government services.
