26. According to Jenny Radesky, digital products are designed to.
- A. simplify routine matters
- B. absorb user attention
- C. better interpersonal relations
- D. increase work efficiency
答案：B
答案句：“Tech is designed to really suck you in,” says Jenny Radesky in her study of digital play, “and digital products are there to promote maximal engagement. It makes it hard to disengage, and leads to a lot of bleed-over into the family routine.”
参考译文：“科技的设计初衷就是让你深陷其中，”珍妮·拉德斯基在她的数字游戏研究中说道，“数字产品旨在促进最大程度的参与。这让人难以抽身，并导致大量问题渗透到家庭日常生活中。”
定位线索：题干“According to Jenny Radesky, digital products are designed to”对应答案句“digital products are there to promote maximal engagement”；文中“promote maximal engagement”对应选项B“absorb user attention”（吸引用户注意力）。
解析：题干问数字产品的设计目的，答案句明确说“digital products are there to promote maximal engagement”，即“促进最大程度的参与”，这与选项B“absorb user attention”（吸引用户注意力）是同义转述。选项A“简化日常事务”、C“改善人际关系”、D“提高工作效率”在原文中均无依据，属于无中生有。
27. Radesky’s food-testing exercise shows that mothers’ use of devices.
- A. takes away babies’ appetite
- B. distracts children’s attention
- C. slows down babies’ verbal development
- D. reduces mother-child communication
答案：D
答案句：She found that mothers who used devices during the exercise started 20 per cent fewer verbal and 39 per cent fewer nonverbal interactions with their children.
参考译文：她发现，在测试过程中使用设备的母亲与孩子的语言互动减少了20%，非语言互动减少了39%。
定位线索：题干“Radesky's food-testing exercise shows that mothers' use of devices”对应答案句“mothers who used devices during the exercise started 20 per cent fewer verbal and 39 per cent fewer nonverbal interactions”；文中“fewer verbal and nonverbal interactions”对应选项D“reduces mother-child communication”（减少母子交流）。
解析：题干问食物测试实验表明母亲使用设备的影响，答案句直接指出使用设备的母亲与孩子的语言和非语言互动都减少了，即“reduces mother-child communication”，对应选项D。选项A“夺走婴儿食欲”、B“分散孩子注意力”、C“减缓婴儿语言发展”均未在原文提及，属于无中生有或偷换概念。
28. Radesky cites the “still face experiment” to show that.
- A. it is easy for children to get used to blank expressions
- B. verbal expressions are unnecessary for emotional exchange
- C. children are insensitive to changes in their parents’ mood
- D. parents need to respond to children’s emotional needs
答案：D
答案句：In it, a mother is asked to interact with her child in a normal way before putting on a blank expression and not giving them any visual social feedback: The child becomes increasingly distressed as she tries to capture her mother's attention. … “Parents don't have to be exquisitely present at all times, but there needs to be a balance and parents need to be responsive and sensitive to a child's verbal or nonverbal expressions of an emotional need,” says Radesky.
参考译文：在实验中，母亲被要求先以正常方式与孩子互动，然后摆出面无表情的样子，不给孩子任何视觉社交反馈：孩子试图吸引母亲注意时变得越来越痛苦。……“父母不必时刻都精致地陪伴，但需要保持平衡，父母需要对孩子的语言或非语言情感需求表达做出回应并保持敏感，”拉德斯基说。
定位线索：题干“Radesky cites the 'still face experiment' to show that”对应答案句中的实验描述及后文观点句“parents need to be responsive and sensitive to a child's verbal or nonverbal expressions of an emotional need”；文中“responsive and sensitive”对应选项D“parents need to respond to children's emotional needs”（父母需要回应孩子的情感需求）。
解析：本题为例证题，例子本身（“still face experiment”中孩子因母亲面无表情而痛苦）不是答案依据，例子后面的观点句“parents need to be responsive and sensitive to a child's verbal or nonverbal expressions of an emotional need”才是关键，正确选项D正是对该观点句的同义转述。选项A“孩子容易习惯面无表情”、B“语言表达对情感交流不必要”、C“孩子对父母情绪变化不敏感”均与原文观点相反或无关，属于偷换概念。
29. The oppressive ideology mentioned by Tronick requires parents to.
- A. protect kids from exposure to wild fantasies
- B. teach their kids at least 30,000 words a year
- C. ensure constant interaction with their children
- D. remain concerned about kids’ use of screens
答案：C
答案句：Tronick himself is concerned that the worries about kids' use of screens are born out of an “oppressive ideology that demands that parents should always be interacting” with their children: “It's based on a somewhat fantasised, very white, very upper-middle-class ideology that says if you're failing to expose your child to 30,000 words you are neglecting them.”
参考译文：特罗尼克本人担心，对孩子使用屏幕的担忧源于一种“压迫性意识形态，要求父母应始终与孩子互动”：“它基于一种有点幻想化的、非常白人的、非常中上阶层的意识形态，认为如果你没能让孩子接触到3万个单词，你就是在忽视他们。”
定位线索：题干“The oppressive ideology mentioned by Tronick requires parents to”对应答案句“oppressive ideology that demands that parents should always be interacting”；文中“always be interacting”对应选项C“ensure constant interaction with their children”（确保与孩子持续互动）。
解析：题干问压迫性意识形态要求父母做什么，答案句明确说“demands that parents should always be interacting with their children”，即“要求父母始终与孩子互动”，对应选项C。选项A“保护孩子免受幻想影响”、B“每年教孩子至少3万个单词”、D“持续关注孩子使用屏幕”均与原文不符，其中B是对“30,000 words”的曲解，原文是“expose your child to 30,000 words”而非“teach”，且不是该意识形态的核心要求。
30. According to Tronick, kids’ use of screens may.
- A. give their parents some free time
- B. make their parents more creative
- C. help them with their homework
- D. help them become more attentive
答案：A
答案句：Tronick believes that just because a child isn't learning from the screen doesn't mean there’s no value to it – particularly if it gives parents time to have a shower, do housework or simply have a break from their child. Pa
参考译文：特罗尼克认为，仅仅因为孩子没有从屏幕中学习并不意味着它没有价值——尤其是如果它能让父母有时间洗澡、做家务或只是从孩子身边休息一下。
定位线索：题干“According to Tronick, kids' use of screens may”对应答案句“it gives parents time to have a shower, do housework or simply have a break”；文中“gives parents time”对应选项A“give their parents some free time”（给父母一些空闲时间）。
解析：题干问特罗尼克认为孩子使用屏幕可能带来的好处，答案句明确指出“it gives parents time to have a shower, do housework or simply have a break from their child”，即“给父母时间洗澡、做家务或休息”，对应选项A“give their parents some free time”。选项B“让父母更有创造力”、C“帮助孩子做作业”、D“帮助孩子更专注”在原文中均未提及，属于无中生有。
