Smartphones have been blamed for everything from taking drivers’ attention from driving to keeping people on the sofa scrolling (滾屏) videos.But the smartphone that seems to be everywhere could just easily increase physical activities if it pushes its owner’s buttons in the right way.

　　New research shows that making social connections through activity-tracking apps gets people to move more.And a separate study on this summer’s “Pokemon Go” phenomenon shows that the smartphone game got players to take more steps than usual.Together,the studies show the potential for smartphones to push a range of people to be more active.

　　People who linked with friends on the activity-tracking app increased their steps by 400 a day on average,compared with people who made no social connections,according to Tim Althoff and two other computer scientists at Stanford University.The effect of social connections declined,but remained significant for five months before the numbers fell back even with users who made no connections.

　　Such insights show the promise of smartphones and games to help with one of the most stubborn public health problems—that even people who want to be active have trouble staying active.

　　An NBA videogame,for example,gives players extra power in the game if they reach a step goal in real life.The app “Zombies,Run!” uses audio stories to push people to run more or run faster.

　　Still,there is room for growth.Only about 4% of all health apps use “gamification”,according to a study published in October in BMJ Open.“Gamification is actually quite closely linked with behavior change techniques,” says Dr.Elizabeth Ann Edwards,the study’s lead author and a doctor and researcher at Queen Mary University of London.

　　【語篇導(dǎo)讀】智能手機(jī)在許多方面受到人們的譴責(zé),但是無處不在的智能手機(jī)如果運(yùn)用恰當(dāng)?shù)脑掃�是有利于人們的鍛煉的,比如“Pokemon Go” 智能手機(jī)游戲讓玩家比平時(shí)多走,而使用音頻可使人們跑得更多或跑得更快。

　　D.They can involve their users in more exercise.

　　答案　D

　　解析　細(xì)節(jié)理解題。根據(jù)第一段中的“But the smartphone that seems to be everywhere could just easily increase physical activities...”可知,無處不在的智能手機(jī)同樣可以增加體力活動(dòng),所以D項(xiàng)符合語境。

　　A.they have more social connections

　　B.they get extra powers in life

　　C.the games increase physical activities

　　D.a life goal has been set step by step

　　答案　C

　　解析　細(xì)節(jié)理解題。根據(jù)第二段中的“...‘Pokemon Go’ phenomenon shows that the smartphone game got players to take more steps than usual.Together,the studies show the potential for smartphones to push a range of people to be more active.” 可知,智能手機(jī)游戲讓玩家比平時(shí)多走,使人們更活躍,所以選C項(xiàng)。

　　3.Who are most likely to exercise more?

　　A.Video watchers on the sofa.

　　解析　推理判斷題。第五段中提到了一個(gè)NBA視頻游戲,如果玩家在現(xiàn)實(shí)生活中達(dá)成目標(biāo),游戲就給他們在游戲中額外的權(quán)力。諸如此類等等來推動(dòng)人們運(yùn)動(dòng)得更多或運(yùn)動(dòng)得更快。由此判斷選B項(xiàng)。

　　4.How does the author try to prove the ease of smartphones?

　　A.By showing the results of some researches.

　　B.By explaining the functions of smartphones.

　　C.By giving vivid description of some games.

　　D.By analyzing the causes of public health problems.

　　答案　A

　　解析　推理判斷題。通讀全文可知,作者通過展示一些研究的成果來論證手機(jī)的易用性,所以A項(xiàng)正確。
