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（頁面布局）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.

Internet/ communications, digital video and audio composition, and desktop publishing are features only offered on computers. With the aid of computers, humankind is entering a new era of civilization.

All people need to sleep. Sleep is a necessary process that promotes proper body functioning and can improve the quality of your life. Not only is the quantity of sleep important, but also the quality of sleep.
Your bedroom should be shaped to your taste and to allow you to sleep in a peaceful environment. One of the biggest mistakes people make in their sleep is to use their bedroom for activities other than sleep. If your bedroom also functions as a command station for your life and work, the likelihood of your sleeping being poor is rather high. Bedrooms should be designed, decorated and used for mainly sleep. TVs, computers and other things should not be in your bedroom if at all possible.
Establishing regular sleeping and waking times can help improve the quality of your sleep especially for those suffering from sleeplessness. Avoid hot food, caffeine, sugar and alcohol at least 4 to 6 hours before your sleep time. Develop a regular exercise program. Proper exercise and nutrition will help improve sleeping patterns. However, avoid exercising 2 hours before sleeping, since this may stimulate your body and make sleeping more difficult.
Establish a pre-bedtime rule that will help focus you on sleep. You can try meditation（沉思）,reading or deep breathing and relaxation. Your bedtime rule should be yours. Do not worry about it fitting into a specific category. Do what is the best for you.
Things such as room temperature, noise and light levels and even your bed mattress can have a lot of effect on the quality of sleep that you experience. Block out distracting noises and lights. You are in your bedroom to sleep and not be distracted by environmental interferences（干擾）.
