53. What do we learn about the author's feelings regarding smartphones and screen time?
- A. They are deep-seated.
- B. They are instinctive.
- C. They are unique.
- D. They are mixed.
答案：D
答案句：Though I've banned most social media, I've still battled smartphone time with my own kids. A lot of the time I wish I could throw my kids' smartphones into the nearest lake. The convenience of communication- when they need a ride home from school after practice, for instance-often feels like it isn't worth the battle to keep their screen time low and productive, and continue to encourage “real-life”activities outside and with friends and family. I understand the addiction and often tell them I'm not sure how I would have handled having a smartphone as a teen. As an adult, I too, struggle with overuse.
参考译文：虽然我禁止了大多数社交媒体，但我仍然在与自己孩子的智能手机使用时间作斗争。很多时候我希望能把孩子的智能手机扔进最近的湖里。通信的便利——例如当他们练习后需要搭车回家时——常常让人觉得，为了保持他们的屏幕时间低而富有成效，并继续鼓励户外以及与朋友和家人的“现实生活”活动，似乎不值得这么斗争。我理解这种成瘾，并经常告诉他们，我不确定自己作为青少年时如何处理智能手机。作为成年人，我也在过度使用中挣扎。
定位线索：题干“author's feelings regarding smartphones and screen time”→答案句“I've battled”“I wish I could throw”“I understand the addiction”“I too, struggle”；文中“battle”“wish”“understand”“struggle”体现矛盾，对应选项D“mixed”。
解析：作者既想扔掉手机（“wish I could throw”），又承认通信便利（“convenience of communication”），既理解成瘾（“understand the addiction”）又自身挣扎（“struggle with overuse”），这些矛盾情感综合体现“mixed”（复杂的、矛盾的）。A项“deep-seated”（根深蒂固）和B项“instinctive”（本能的）未体现矛盾；C项“unique”（独特的）文中无依据，均属无中生有。
54. What does actress Kate Winslet think about the world of social media?
- A. It poses increasing challenges to parents trying to ensure internet safety.
- B. It scares parents because they don't really know what is on the screen.
- C. It is a sphere difficult for parents and their teens to navigate.
- D. It is full of uncertainties frightful to parents and their teens.
答案：B
答案句：“I do definitely feel that the world of social media is frightening to parents because we don't really know what's there,”she said.“We don't know how our children are using it. We don't know the effects that it's really having on them.”
参考译文：“我确实觉得社交媒体世界对父母来说是可怕的，因为我们真的不知道那里有什么，”她说。“我们不知道我们的孩子如何使用它。我们不知道它真正对他们产生的影响。”
定位线索：题干“Kate Winslet think about the world of social media”→答案句“the world of social media is frightening to parents”；文中“frightening”“don't really know what's there”对应选项B“scares parents because they don't really know what is on the screen”。
解析：答案句直接引用温斯莱特的话，她认为社交媒体世界“frightening to parents”，原因是“don't really know what's there”，即父母不知道屏幕上有什么，与B项“scares parents because they don't really know what is on the screen”完全对应。A项“挑战”和C项“难以导航”是文章其他内容，非她观点；D项“不确定性和恐惧”虽接近，但“frightful to parents and their teens”中“teens”无依据，范围扩大。
55. What message does the author try to convey in the last paragraph?
- A. Parents have to be concerned about dangers to their teens in both real and virtual worlds.
- B. Governments have responsibilities in regulating social media and teens' smartphone use.
- C. Parents should provide guidance to their teens in the use of social media.
- D. Online dangers are as serious as problems with teenagers' mental health.
答案：A
答案句：I don't think the U.S.government should regulate social media and teen smartphone use, but it is a vital topic for parents to understand and take seriously. Unfortunately, now, parents don't just have to worry about real-world dangers, but all the ones sneaking online and the effects they have on teenagers and their mental health.
参考译文：我不认为美国政府应该监管社交媒体和青少年智能手机的使用，但这是父母需要理解并认真对待的重要话题。不幸的是，现在父母不仅需要担心现实世界的危险，还要担心所有潜藏在网上的危险及其对青少年和他们心理健康的影响。
定位线索：题干“message in the last paragraph”→答案句“parents don't just have to worry about real-world dangers, but all the ones sneaking online”；文中“real-world dangers”和“sneaking online”对应选项A“dangers in both real and virtual worlds”。
解析：末段作者明确表示父母不仅要担心现实世界的危险，还要担心网上潜藏的危险，即需同时关注现实和虚拟世界的危险，与A项“Parents have to be concerned about dangers to their teens in both real and virtual worlds”对应。B项“政府责任”与作者“I don't think the U.S.government should regulate”相反；C项“提供指导”文中未提；D项“网上危险与心理健康问题同等严重”偷换概念，原文强调两者并存而非比较严重性。
