　　9.Internet — A Two-edged Sword
　　Internet is playing an increasingly important role in people’s life. As a newborn information delivering system, the Internet has made seas of information available at our fingers’ tips. Besides, the Internet serves as the most convenient means for communication. Through the Internet, people can discuss various problems and make friends who share common views.
　　But just as a coin has two sides, Internet has its own drawbacks which should not be neglected. First, it costs an alarming amount of money to construct the system and the cost is very high to most Chinese consumers. Second, it is sometimes difficult for people to find the right information they are looking for since there is too much rubbish on the net. Finally, it is also difficult to prevent the net from the invasion of criminals.
　　Therefore, the Internet should be viewed as a two-edged sword, which presents us with both conveniences and troubles. But we should not give up eating for fear of choking. The best policy, as I see it, is to further develop the net and exert proper supervision over it so that it can benefit us in a better way.
