随着网络的飞速发展, 智能手机（Smart phone）的广泛应用, 我们身边的低头族随处可见。某职业高中高一二班正举行主题班会, 对过度依赖手机现象发出倡议。
　　任务一 阅读相关信息, 完成任务单。（本任务5个空, 共5分）
　　Smart phone feels like your body? Are you phubber（低头族）？ A global survey has found that many people can’t live without their smart phones. They never leave home without them. While eating with family members or getting together with friends, some are always busy playing with their smart phones. It has bad effects on the relationship with their relatives and friends. Even worse, when some people cross the street, they still concentrate on their smart phones which can easily cause traffic accidents. It’s too dangerous. And others stay up playing games. I think it really does great harm to their health, study and work. Many people don’t use the smart phones for the real purpose, they use them for chatting, surfing and playing games.
　　As students, it’s time for us to study hard. We’d better make good use of smart phones. Don’t depend on smart phones too much. Let’s put down the smart phone and spend more time on study.
　　Refuse to be phubbers!
