问题     It’s our guilty pleasure: Watching TV is the most common everyday activity, after work and sleep, in many parts of the world. Americans view five hours of TV each day, and while we know that spending so much time sitting【C1】______can lead to obesity(肥胖症)and other diseases, researchers have now quantified just how【C2】______being a couch potato can be.

【C1】
选项
答案H
解析 副词辨析题。空格位于动词sitting后面，此处应填入副词。由上文可知“花这么多时间——坐着”是指坐着看电视，这不是积极的活动，所以答案是H)passively“消极地”。备选副词中，previously意为“先前”，与文意不符，因此排除。
