In recent years, technology has been advancing at an unprecedented rate, bringing about both positive and negative impacts on society. On one hand, it has greatly improved our lives by making tasks more efficient and convenient. For instance, smartphones allow us to access information instantly and stay connected with people around the globe. However, the overuse of technology has also led to a series of problems, such as addiction, privacy concerns, and the ______ of social skills.

The rise of social media platforms has further complicated the issue. Users are constantly bombarded with news, updates, and advertisements, making it difficult to ______ from the constant flow of information. This not only affects individuals' mental health but also disrupts their daily routines and productivity.

Moreover, the rapid pace of technological advancement has created a digital divide, where those who have access to the latest technology enjoy numerous benefits, while those who don't are left behind. This divide can exacerbate existing social inequalities and create new ones, such as the ______ gap between urban and rural areas.

However, it's not all doom and gloom. Technology also offers solutions to many of the problems it creates.

文章概要

近年来，科技以前所未有的速度发展，给社会带来了正反两面的影响。一方面，它极大地改善了我们的生活，使任务更加高效便捷；另一方面，过度使用科技也导致了一系列问题，如成瘾、隐私担忧以及社交技能的退化。社交媒体的兴起更是加剧了这一问题，用户不断被信息轰炸，难以从持续的信息流中抽离，影响心理健康和日常生活。此外，科技快速发展还造成了数字鸿沟，加剧了社会不平等。但科技也提供了解决问题的方案，如远程医疗和可再生能源技术。

答案

A. erosion（侵蚀）

C. disconnection（断开连接，抽离）

D. disparity（差异，不平等）

解析

第一空选择A（erosion），因为“erosion”在这里指社交技能的逐渐丧失或退化，与“social skills”的搭配符合语境。

第二空选择C（disconnection），强调用户难以从不断的信息流中“断开连接”或“抽离”，反映了社交媒体对人们日常生活的负面影响。

第三空选择D（disparity），指的是由于科技不平等使用导致的城乡之间或其他社会群体之间的“差异”或“不平等”，与后文提到的“加剧社会不平等”相呼应。

通过以上解析，可以看出英语四级选词填空不仅考察词汇知识，还涉及对文章整体内容的理解和逻辑推理能力。希望这个示例能够帮助你更好地准备英语四级考试。
