Over the past twenty years or so, great changes have taken place in our life. Take my family
for example. In the past, when my parents wanted to tell something to the relatives or friends in
another city, they had to send the letters. And they could listen to the radio for news and other
information only. But now we can make a telephone call at home or at any other places to talk to
the relatives and friends. And we can watch the news and other programs on TV every day. So our
life today is much more comfortable than it was in the past.
