46. What does the author believe regarding social media?
- A. To stop children using it is unrealistic and inadvisable.
- B. It helps both adults and children to organise their lives.
- C. It poses problems to both parents and children.
- D. A world without it is really hard to imagine.
答案：A
答案句：While younger children should not be on platforms where 13 is the minimum age, it is neither practical nor desirable to imagine a world in which teenagers are prevented from accessing the platforms and messaging systems that the adults around them use to organise their lives.
参考译文：虽然年幼的孩子不应该使用以13岁为最低年龄限制的平台，但想象一个青少年被禁止使用周围成年人用来组织生活的平台和通讯系统的世界，既不现实也不可取。
定位线索：题干“What does the author believe regarding social media?”→答案句取自第1段“it is neither practical nor desirable to imagine a world in which teenagers are prevented from accessing the platforms”；文中“neither practical nor desirable”对应选项A“unrealistic and inadvisable”。
解析：题干问作者对社交媒体的看法，答案句明确指出阻止青少年使用社交媒体“既不现实也不可取”，与选项A“阻止孩子使用它是不现实和不明智的”同义转述。选项B“帮助成人和孩子组织生活”是原文中“adults around them use to organise their lives”的偷换概念，原文只提到成人，未提孩子；选项C“给父母和孩子都带来问题”范围扩大，原文只提孩子；选项D“没有它的世界难以想象”是原文“imagine a world”的曲解，原文说的是阻止使用难以想象，而非没有社交媒体的世界。
47. What do we learn from the passage about British teenage girls?
- A. The more frequently they interact on social media, the more they experience harassment.
- B. The more time they spend on social media, the more likely they suffer from depression.
- C. Most of them are engaged on social media for at least three hours a day.
- D. They spend half as many hours on social media as British teenage boys.
答案：B
答案句：The finding that the alarmingly high rate of depression in British teenage girls is closely correlated to time spent on social media is extremely concerning. Research found that two in five girls are on social media for at least three hours a day-with half as many boys engaged to the same extent.
参考译文：英国少女抑郁症发病率高得惊人，且与社交媒体使用时间密切相关，这一发现极其令人担忧。研究发现，五分之二的女孩每天使用社交媒体至少三个小时，而男孩中只有一半的比例达到同样程度。
定位线索：题干“What do we learn from the passage about British teenage girls?”→答案句取自第2段“depression in British teenage girls is closely correlated to time spent on social media”；文中“closely correlated to time spent on social media”对应选项B“The more time they spend on social media, the more likely they suffer from depression”。
解析：题干问关于英国少女我们能了解到什么，答案句明确指出少女抑郁症与社交媒体使用时间密切相关，即时间越长越可能抑郁，对应选项B。选项A“互动越频繁越受骚扰”是原文“More than a third of depressed girls have experienced online harassment”的过度推断，原文未提频率；选项C“大多数女孩每天至少使用三小时”是原文“two in five”的偷换概念，原文是五分之二而非大多数；选项D“她们使用社交媒体的时间是男孩的一半”是原文“half as many boys”的曲解，原文指男孩中达到同样程度的人数比例是女孩的一半，而非时间。
