[解析]
(1)F.推理判断题。上文"However,if the social media do not handle properly,it can become an addiction that can dominate your time and affect your work as well as relationships.(然而,如果社交媒体处理不当,它可能会成为一种瘾,支配你的时间,影响你的工作和人际关系)"讲社交媒体处理不当可能带来的问题,下文的几个小标题"Turn off notifications (关掉提醒)"和"Be cautious of time spent on social media(留心花在社交媒体上的时间)"列举了避免对社交媒体成瘾的办法,F项"Now,here are some steps on how to avoid the addiction of social media (下面是一些如何避免社交媒体成瘾的措施)"承上启下,引出措施。故选F项。
(2)C.联系上文题。上文"They may disturb your normal routine because we are continuously drawn to our phones with every buzz sound or flash from the notification light.(它们可能会扰乱你的日常生活,因为我们不断地被手机的每一个嗡嗡声或提示灯的闪光所吸引)"讲手机提醒会扰乱日常生活,由此推知"when you stop your notifications,(当你关掉提醒时)",你就能更好的专注于日常生活,C项"you might find it easier to focus on your daily routine(你会发现更容易专注于日常生活)"符合语境。故选C项。
(3)A.段落标题题。设空处为小标题,根据段中"You have a lot of time to do many things,but you may waste all the time on social media.If you get a new hobby to fill your spare time...(你有很多时间可以做很多事情,但你可能会把所有的时间都浪费在社交媒体上。如果你有一个新的爱好来填补你的业余时间……) "和"You could also learn a new skill or do something you have always wanted to do but never had time. (你还可以学习一项新技能,或者做一些你一直想做但没有时间做的事情)"可知,在本段中作者建议用新的爱好来填补空闲时间,从而减少使用社交媒体的时间,由此推知,A 项"Get a new hobby(培养新的爱好)"是最佳小标题。故选A项。
(4)E.联系上文题。上文"If you get a new hobby to fill your spare time,...(如果你有一个新的爱好来填补你的业余时间,……)"作出假设,E项"then you could limit the use of social media (然后你就可以限制社交媒体的使用)"是上文假设产生的结果,爱好填补了业余时间,也就意味着用于社交媒体的时间减少,得以限制。故选E项。
(5)D.语境判断题。"Be cautious of time spent on social media (留心花在社交媒体上的时间)"作为小标题,总领全段,D项"Social media is a powerful force that it makes users lose all the sense of time.(社交媒体是一股强大的力量,它让用户失去时间感) "是对小标题的解释说明,社交媒体会让用户失去时间感,所以要留心花在它上面的时间。故选D项。
