Important invention

There are a lot of modern inventions nowadays: mobile phone, the TV, radio, motor car, computer, photography and others. People use them every day and they couldn’t live without all these things: for example we use mobile phone when we want to talk with our friends, we use radio to listen to something interesting and etc.

In my opinion all of these objects are very important, but computer is the most important invention for me. Computer is modern and useful technical object. It makes our life easy and develops us. We use computer every day: we listen to the music, download and watch a lot of films, videos and games. Using computer we can communicate with friends, relatives and others. Sometimes, we sit before the screen very long time and find a lot of information which we need.

Our world is really modern and we have a lot of inventions which can help us in life….
