Since then, it has become a familiar term for a person who spends a lot of time sitting, and little time exercising. Although there does not seem to be any particular reason why the term “couch potato” is used rather than “couch tomato”， a person may become a “couch potato” because living this way is said to make you round like a potato.① The term is also said to have something to do with high－calorie(卡路里) foods like potato chips. People now would say “couch potato” whenever they talk about overweight and obesity(肥胖). Indeed, “couch potatoes” are believed to have heart disease risks, which can be avoided by regular exercise.② It is true that technology and modern life in general make us sick, fat, lazy and physically/mentally soft.③ The more time people spend using technology, particularly televisions and computers, the less time they will spend being physically active. “Couch potato” kids are a particular concern. Media reports repeatedly claim that children today are fatter than their elder generations, but less athletically skilled, less interested in physical activities and more addicted(上瘾的) to “junk food” and technology such as televisions and computers. The message is clear: Today's children are fat because they are lazy and eat too much. Moreover, because technology is becoming more sophisticated(复杂的), children are less able to resist(抵制) technology's attraction, and are more likely to spend more time using technology, less time doing physical activities and, therefore, more likely to be fat.④ 【语篇导读】本文是一篇说明文。文章主要讲述了“沙发土豆”这个概念，以及人们随着科技的发展变成了“沙发土豆”，即逐渐地缺乏锻炼、影响身体健康的现象。 一、 阅读短文，从每题所给的A、B、C、D四个选项中选出最佳选项。 ( ) 1.
