材料二：工匠精神，是指工匠对自己的产品精雕细琢、精益求精的精神理念。工匠精神落在个人层面，就是一种认真精神，敬业精神。践行社会主义核心价值观需要在平凡的工作中弘扬工匠精神。中航工业西安飞机工业（集团）有限公司的普通工人李世峰，凭着一把得心应手的榔头和对技术的执着，成为我国飞机制造领域知名的钣金工大师。榔头在他的手里是那样的听话和灵活，在加工零件时想敲哪儿就敲哪儿，想敲成什么样就敲成什么样。当然，这样的高超技术不是天生的，用李世峰自己的话说，他的技术是用数十年如一日平凡的坚持、磨炼，敲榔头敲出来的。宝剑锋从磨砺出，正是经过一次又一次难活、苦活的磨炼，李世峰的钣金工技术才日益精湛，零件一次交验合格率多年来一直是100%，人们称为出神入化的榔头大师。平凡岗位上的李世峰，书写着一线劳动者的平凡。

    Texting while walking is something that most of us are guilty of. We can't help replying to that message we just received. However, while it's fun to keep up with the latest gossip, we may actually be putting ourselves in danger.

    A team of researchers from two UK universities recently found that people who use their phones while on the move walk differently than usual.

    “Recently, a person in front of me was walking very slowly and weaving (迂回行进), and I thought, 'Is this person drunk?'” Matthew Timmis, co-author of the study, told the Guardian.

    It turned out that the person was just texting. Inspired by this, Timmis and his team set out to discover the effects of phone use on how we navigate streets.

    A group of 21 volunteers were asked to walk around a simulated (模拟的) street, complete with obstacles such as a step. The participants traveled the course a total of 12 times each, either writing or reading a message, making a call, or with no phone at all.

    It took the volunteers 118 percent longer to complete the course when using a phone. They also focused on the step obstacle 60 percent more and paid attention to the travel path 51 percent more when they weren't using a phone.

    Although there were no accidents, Timmis believes we should still be aware of what's going on around us.

    “The big risk here is suddenly-appearing hazards (危险), like a pedestrian (行人) suddenly walking in front of you,” he told the Guardian. “You are not going to be able to respond to that as efficiently, which increases the risk of injury.”

    To bring attention to the dangers of “text walking”, a temporary “texting lane” was set up in Antwerp, Belgium in 2015. And earlier this year, a special crosswalk featuring flashing red lights on the ground to get the attention of texters was set up in Wuhan, Hubei province.

    “Texting while walking can lead to collisions with poles or other pedestrians. You could even be endangering your own life when you cross the street without looking up,” a spokesperson for the company that made the Antwerp texting lane told Yahoo News.
