Among them, the computer is one of the most important inventions. It has changed the history. Most people think computers are very useful machines and they have become an important part in their daily lives. They really help them a lot. For example, computers can help them save much time, and they can help them work out many difficult problems. In our country,the government (政府) encourages everyone to learn computer skills. So, today more and more families own computers. Parents often buy computers for their children. They hope computers can help their children improve (提高)their studies. However, many students play computer games. Besides, they use computers to watch videos or chat with their friends on QQ or WeChat instead of studying. So many teachers and parents complain (抱怨) that computers cannot help children with their studies and are harmful to them. Then some parents and teachers try to stop students from using computers in their life. In other parts of the world, even some scientists don't like computers. They think that these machines have caused millions of people to lose their jobs and have brought people a lot of troubles. Will computers really bring troubles to people? It depends on people themselves. In my opinion, we should use computers wisely, making sure that computers are just tools for our growth and development rather than becoming a source (来源) of trouble.
