53. What do families think of live video chat according to surveys?
- A. It should not be regarded as screen time.
- B. It helps babies to develop their verbal skills.
- C. It is not as harmful as playing games on laptops.
- D. It is a good substitute for video viewing.
答案：A
答案句：Surveys indicate that families already popularly believe that“Face time doesn't count”, or at least that the benefit of virtual visits with grandparents or other relatives outweighs the potential cost of exposing babies to the laptop or smartphone.
参考译文：调查表明，家庭普遍认为“Face time不算数”，或者至少认为与祖父母或其他亲属进行虚拟访问的好处超过了让婴儿接触笔记本电脑或智能手机的潜在成本。
定位线索：题干“families think of live video chat”对应原文“families already popularly believe”；文中“Face time doesn't count”对应选项A“should not be regarded as screen time”。
解析：题干问调查中家庭对视频聊天的看法。答案句指出家庭普遍认为“Face time不算数”，即不将其视为屏幕时间，对应A选项。B选项“有助于语言发展”原文未提；C选项“不如玩笔记本电脑游戏有害”是无关比较；D选项“是视频观看的良好替代”偷换概念，原文说的是虚拟访问而非视频观看。

- D. They can relate what they learn on the screen to real life situations.

参考译文：对于2至5岁的学龄前儿童，有更多证据表明他们有能力将知识从屏幕迁移到现实世界，包括早期读写和数学。
定位线索：题干“preschoolers ages 2 to 5”对应原文“preschoolers ages 2 to 5”；文中“transfer knowledge from screens to the real world”对应选项D“relate what they learn on the screen to real life situations”。
解析：题干问作者关于2至5岁学龄前儿童的说法。答案句指出他们能将知识从屏幕迁移到现实世界，对应D选项“将屏幕所学与现实生活情境联系起来”。A选项“很好理解屏幕内容”是AAP建议中“帮助理解”的偷换；B选项“无需父母指导自主学习”与后文“co-view”矛盾；C选项“发展数字素养”偷换概念，原文说的是早期读写和数学。
