We live in the "computer age". People, like scientists（科学家）, writers, teachers, and even students use computers to do much work. Computers are very important because they can work faster than us and make fewer mistakes. Computers can help people do lots of work. Writers use computers to write. Teachers use them to teach. Computers can also remember what you put into（输入）them. Computers are very useful and helpful.
They are our good friends. Do you want to have a computer?
