Over the past twenty years or so, great changes have taken place in our life. Take my family for example. My parents contacted others mainly by sending them letters in the past, but now we call long distance at home. And once my parents listened to the radio for news and other information, but now we watch the news and other programs on TV. Another big change is in the housing conditions. When they got married about twenty years ago, my parents lived in a small room crowded with furniture, but now we have moved into a big new three-room apartment. In short, changes in our life in the past twenty years have brought us comfort and convenience.
