Upon entering kindergarten at age 5, a child already has spent more hours watching TV than he or she would spend earning a college degree. By the Child’s 18th birthday, more time has been spent watching TV than on any other single activity except sleep.Clever advertising aimed at children certainly influences them. Very young children don’t even distinguish between commercials and programs . Is it fair to show advertising to young children? Many people think that it is not .The US government has yet to control children’s advertising ,but Canada imposed a limited ban on commercials aimed at children .
回答：    社会科学家，教师和家长对儿童所选择观看的电视节目感到困扰。这些群体都很关心媒体对青少年和儿童影响。他们担心电视暴力的作用就象社会上和商业上的糖衣食物。但是，最重要的，他们觉得电视是造成中小学生数学和阅读成绩下降的一个因素。由于将过多的时间的时间花费在看电视上，儿童是花费很少的时间阅读和独立思考。 
    确实是这样，青少年平均每天花费4个小时看电视，每星期花费25个小时在电视上。刚进入幼儿园的5岁孩子花费在看电视上的时间比他获取一个大学学位的时间还要多。到他们18岁生日时，他们花费在看电视上的时间超过了其他任何单一的活动，当然除了睡觉。 
    精明的广告将目标瞄准了儿童并对他们造成了一定的影响。非常年幼的儿童甚至分不清商业广告和节目。这对年幼的孩子来说又是否公平呢？很多人认为这是不公平的，美国政府尚未出台法令来规范儿童广告，但加拿大施加了限制，禁止针对儿童的商业广告。
