This has led many to try digital detoxing ( 排毒).(持续‘在线’的感觉促使人们重新考虑自己在数字世界中的平衡,这导致许多人尝试进行数字排毒。)”解释了为什么人们需要“数字排毒”。C选项“However, it can also be exhausting.(然而，它也会让人精疲力竭。)”通过转折词“However”引出数字生活的负面影响，与前文构成转折，同时该选项中的“exhausting”与后文的“on”形成呼应，持续在线的感觉让人精疲力竭，该选项符合语境。 45．此空为段落小标题。根据该段内容“Thus, finding enjoyable hobbies that result in play can be crucial. People engaging in play for its own sake can reduce stress levels and boost digital well-being.(因此，寻找能带来乐趣的爱好至关重要。人们纯粹为了玩乐而参与，可以降低压力水平并提升数字幸福感。)”可知，本段的核心建议是鼓励人们为了纯粹的快乐去玩耍。B选项“Learn to play for pure joy.(学会为了纯粹的快乐而玩耍)”精准概括了该段主旨，且符合小标题的祈使句结构。 46．上文“Therefore, during a digital detox, it is vital to fill your cup with community.(因此，在数字排毒期间，用社群来充实自己是至关重要的。)”强调了在数字排毒时建立社群联系的重要性。F选项“This can be done through existing or new friendships.(这可以通过现有的或新的友谊来实现。)”中的代词“This”指代前文提到的“fill your cup with community”，并且“friendships(友谊)”是对“community(社群)”的具体化说明，符合语境。 47．上文“Yet, the ability to just be can allow time for reflection.(然而，仅仅独处的能力可以留出反思的时间。)”强调了独处和反思的价值。G选项“It helps you consider what makes you happy and healthy.(它帮助你思考什么让你感到快乐和健康。)”中的“It”指代前文的“reflection(反思)”，进一步解释了反思的具体作用，即思考什么能带来快乐和健康，与下文“Find moments where you can step away to recharge(找时间抽身去充电)”在逻辑上顺承，符合语境。 48．该段段旨“Set appropriate goals.(设定适当的目标。)”指出要设定适当的目标。后文“We recommend identifying specific goals for yourself related to your own digital well-being.(我们建议为你自己设定与数字健康相关的具体目标。)”说明空处应是一句引出“设定目标”重要性的背景铺垫。E选项“Willpower alone can’t beat smartphone reliance.(仅靠意志力无法克服对智能手机的依赖。)”指出了人们面临的困境即仅靠意志力无法克服对智能手机的依赖，因此需要设定具体目标，该选项符合题意。 学科网（北京）股份有限公司 $
