   Great changes have taken place in the way of communication in people's life in recent years.

    In the past, people kept in touch with each other mainly by writing letters or using the public telephone. But now almost everyone has his own mobile phone. People can communicate with each other almost at any place and at any time. What's more, people have easy access to the Internet, which enables them to send and receive e-mails whenever they like. With these changes, people's pace of life has been quickened and people's work has been made more efficient. It used to take several days to hear from each other, but now it takes only several minutes, even if they are in two different continents. In a word, people have an easier life nowadays.
