Computers are helpful because they offer a wide range of functions and services that are not available anywhere else. There are four main uses: word processing, Internet/ communications, digital video/ audio composition, and desktop publishing. The word processing capabilities of computers are amazing. They can automatically correct your spelling and grammar mistakes. The cutting and pasting features are incredibly simple and very useful for revision. Having a digital backup is an added benefit. All of these things help writers get the job done. With desktop publishing, you can create page layouts(页面布局)for entire books on your home computer. The Internet is one of the greatest inventions created by humans. It is a huge network of computers, each with the ability to contact any of the others. Vast amounts of information can be found on the Internet. It is the ultimate form of media, a combination of newspaper, radio and television. Using the Internet, any two people anywhere can communicate for free, whether it is by text or voice. New uses are being found for the Internet every day. Audio/ video editing and composition have been made much easier by computers. Cutting and pasting no longer involve using scissors and tape on large reels of film. It no longer costs thousands of dollars of equipment to make a film or to compose music. Now musicians can compose their own songs and publish them without having to obtain a record contract. Film-makers can produce work from their own homes. Anybody who owns a computer can now enter the field of media production.
