Throughout human history, man has invented so many things that enable the civilization to move forward all the time. After entering the 20th century, the inventions seemed to be boomed, which have had a great impact on our lives. For one thing, the bicycles. This easy and small means of transport can take us to the nearby shops and banks and schools quickly and conveniently. And it does not use any oil and brings no pollution and does no harm to the environment. Nowadays, it has become a popular way people can use to do physical exercises. For another, computers. Computers, linked with the world wide web, play a vital role in both our lives and work. We use computers to search for information, to read news and magazines, to communicate with people all over the world, just to list a few of the functions. It is very difficult to imagine a life in the 21st century without the access to computers and internet.
