【今日主题】
那么为何在美国会有couch potato(沙发土豆;沙发马铃薯)这种说法呢?I am told the American couch potato has been a part of American tradition。我听说Couch potato已经成为美国文化的一部分了。那么今天我们就来透视一下关于“沙发土豆”“沙发马铃薯”的美国文化。这就是我们今天的“早餐”。
【文化透视】
Robert Armstrong, an artist from California, developed the term couch potato in nineteen seventy-six. He drew a caricature in which there is a potato lying down on a couch to concentrate it's attention on watching television. Several year later, he listed the term as a trademark with the United States goverment. Mr. Armstrong also wrote a funny book about life as a full-time television watcher. It's called the "Official Couch Potato Handbook". So, a couch potato has widely been used by people.
