参考答案

【正确答案：C】

Para 5 ① Playing video games encourages immediate content.② And hours of watching TV shows with canned laughter only teaches kids to process information in passive way.③At the same time, listening through earphones to the same monotonous beats for long stretches encourages kids to stay inside their bubble instead of pursuing other endeavors.④All these activities can prevent the growth of important communication and thinking skills and make it difficult for kids to develop the kind of sustained concentration they will need for most jobs.

①玩电子游戏会让人获得即时的满足感。②连续数小时看带有预先录制笑声的电视节目只会教孩子用被动的方式处理信息。③与此同时，长时间戴耳机听单调的强节奏音乐将诱使孩子沉浸在自己的幻想世界而非努力进取做其他事情。④所有上述业余活动都可能妨碍重要的交流和思考技能的培养，并使孩子很难培养大多数工作所需要的持续注意力。

本段给出作者的第四条建议。本段结构与上一段截然相反，上段是“总分模式”，而本段则是“分总模式”，具体来讲：①②③都在分述孩子的具体业余活动，④则做归纳总结(All these activities),由此可知④是本段主旨句，比对选项可发现与C项对应，All these activities对应C项的 Leisure Activities, prevent the growth of...和 making it hard to develop...则对应 C项的Place Time Limits,故 C正确。
