Smartphones have been blamed for everything from taking drivers’ attention from driving to keeping people on the sofa scrolling (滚屏) videos. But the smartphone that seems to be everywhere could just as easily increase physical activity 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 thousands 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 increase their steps by 400 a day on average over the next week, 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 powers in the game if they reach a step goal in real life. The app “Zomies, 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,” such as point-scoring or competition, 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.

Shortly after my fourth birthday, my parents and I arrived from China in Sydney, Australia. It was 1991 and my mother had left behind everything she knew-family, friends and career.
Yet within two years, my parents’ marriage had broken down. After one particularly unpleasant fight, my mother left my father, taking me with her. With no family or friends, and in a country where she couldn’t even communicate, she took me to Chinatown, the only area of Sydney she was familiar with. That night she laid me on a bench in Dixon Street, packing suitcases around us for security. I will never forget the despair in her face that night.
At around 4 am, a group of four young Chinese men noisily exited a club nearby. I remember them falling silent as they saw us. They approached and asked my mother why she was sleeping on the streets with such a young child. My mum burst into tears as she told them our story. Without hesitating, they bundled me up, took our suitcases, and drove us to their students housing.
In the weeks that followed, the men looked after us with a youthful enthusiasm. Being poor students living on their own for the first time, they simply knew how to cook in a clumsy way. However, they insisted that a child should have homemade meals. They quickly adjusted their lives around us, buying fresh food, cooking, teasing me to make me laugh, and advising my mum on how to sort out her life.
Eventually, Mum reconciled (和解) with Dad and we moved back in with him, although they continued to split and make up several times.
Gradually we lost touch with the men as we all moved on. But at every milestone of my life-graduations, entering university, getting a good job-I never forget that all of this was made possible because 22 years ago, a group of complete strangers took us in and shared everything they had to save us from life on the street.
1.Why did Mom and I stay in Dixon Street that night?
A. We were waiting for the Chinese men.
B. Mom knew nobody in Australia at all.
C. It was safe to slay there for night.
D. We had no other place to go.
2.How did the students feel the moment they saw us in the street?
A. Ashamed. B. Shocked.
C. Amused. D. Nervous.
3.What message is conveyed in the passage?
A. There is no perfect husband or wife in marriage.
B. It’s the timely help to someone in need that counts.
C. It’s a great challenge for the Chinese to study abroad.
D. Childhood memory functions to guide present behavior.
