For one, the sheer number of hours we pass watching TV dwarfs the time we spend on anything else. And other studies have found that watching ads for beer and popcorn may make you more likely to 44 them.Even so, the authors admit that they didn’t compare different sedent ary activities to 45 whether TV watching was linked to a greater risk of diabetes, heart disease or early death compared with, say, reading.（五）C.beneficialD.challengesA.]B.announcingmitmentponentG.contestsH.critically I.develop J.distributingN.potentialK.enhance L.'M.entitledO.properly P.qualified Q.retainThe .
