    A scientist once said that the Internet was the  world’s largest library,but that all the books were on the floor!In other ,it’s full of information but it can  be difficult to find just what you’re looking for. The  Internet has another drawback,too. Anyone can create a website,which means you can find websites about every!subject imaginable. Unluckily,it also means that a lot of   what is written on them isn’t true!    

   The Internet provides more than just information. There are sites where you can download (下載）music I and films either for free or for a small charge (收費(fèi)）.Other sites allow you to get in touch with people from all!over the world and there are some great online shops. On  Bay (易趣網(wǎng)),for example,people sell used clothes,    CDs and even cars very cheaply.  The Internet has changed the way we work and communicate,but we shouldn’t depend on it too much. Because of its size,it’s very difficult to control and a lot of the information isn’t worth reading. Some people also fear that surfing the net (上網(wǎng)）has taken the place of other healthier activities,especially for young people. Whether you like it or hate it,you’d better get used to it because it’s here to stay!
