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 get the news by watching tv. another big change is in my living conditions. when they got married about twenty years ago, my parents lived in a small room crowded with fiirniture. but now we have moved into a big new three-room apartment. in short, our life has become comfortable and convenient.

　　在过去的20年中，我们的生活发生了巨大的变化。 以我家为例。从前，我父母与其他人联系主要是通过书信，但现在我们可以在家打长途了。

　　以前我的父母都是听收音机来了解新闻和其他信息，但现在我们能观看电视新闻和其他节目了。另一个大的变化是居住条件方面。20年前我的父母结婚时，只居住在一间拥挤的小屋子里，但现在我们已经搬入一套三室一厅的套房里面。简言之，我们的生活变得舒适而方便。
