Rory Glover, from Leeds in the North of England, opened the app on Tuesday to check a prescription and noticed that he had around 50 videos in the “Consultation Replays” section of the app that didn't belong to him, according to BBC News.“I was shocked，” Glover told the BBC. “You don't expect to see anything like that when you're using a trusted app.It's shocking to see such a monumental error has been made.” Babylon said it takes security very seriously and that it has contacted the affected patients to apologize. “On the afternoon of Tuesday 9 June we identified and resolved an issue within two hours whereby one patient accessed the introduction of another patient's consultation recording，” a Babylon spokesperson said.“Actually, we have a long way to go to cope with the private matter, but we will take it really seriously，” he added. 语篇导读 主题语境：人与社会/科学与技术。本文为新闻报道，报道了虚拟医生用巴比伦健康系统意外向用户显示其他患者与医生咨询的视频的事件。 1．What is the main cause of showing other patients' consulting videos?

Sheila, aged 59, says, “I joined to see what my grandchildren are doing, as my daughter posts videos and photos of them.It's a much better way to see what they're doing than waiting for letters and photos in the post.That's how we did it when I was a child, but I think I'm lucky I get to see so much more of their lives than my grandparents did.” Interestingly, Sheila's grandchildren are less likely to use Facebook themselves.Children under 17 in the UK are leaving the site—only 2.2 million users are under 17—but they're not going far from their smartphones.Chloe, aged 15, even sleeps with her phone.“It's my alarm clock so I have to，” she says.“I look at it before I go to sleep and as soon as I wake up.” Unlike her grandmother's generation, Chloe's age group is spending so much time on their phones at home that they are missing out on spending time with their friends in real life.Sheila, on the other hand, has made contact with old friends from school she hasn't heard from in forty years. “We use Facebook to arrange to meet all over the country，” she says.“It's changed my social life completely.” Parents have an important role to play if they want their kids to spend more time in real life.Peter, 38, who spends most of his time in front of a screen, is recently determined to set a better example to his kids.In the evening or at weekends, he would leave his smartphone home and take his kids out to nature. 语篇导读 主题语境：人与社会/社会热点问题。本文为说明文，通过举例说明了老年人和他们的孙辈使用社交媒体的不同习惯，以及作者对社交媒体的看法。 5．What can we learn from Paragraph 1?
