　　Internet in China
　　According to the above chart, the number of the people who go on the Internet has increased from 3.04 million in 1999 to 118 million in 2004. This indicates that Internet has gained its popularity in China at a very high speed.
　　There are many reasons for Internets rapid development in China. First, as a convenient source of information as well as an efficient means of communication, Internet becomes more and more useful to our study and work. Second, due to fierce competition computer companies have lowered the price of their products. The cheaper computers become, the more users there are. With computer, they can easily have access to the Internet. In addition, with the development of our society and the improvement of our living standard, people in China pursue a more colorful life with Internet. Some people download music and movies from the Internet, some join various clubs and make friends on the Internet, some even often do some shopping through the Internet.
　　Internet is also a sword with two edges. It brings about troubles for us. One common problem is computer viruses. They spread very quickly through the Internet and cause great damage to computer users. Another is crime committed through the Internet. As a result, we feel happy about the rapid development of Internet in China but at the same time we should guard against its negative effects.
