美国每年五千人死于开车发短信
<p>一份研究报告显示，美国每年有5000多人死于开车发短信和打电话，而20岁以下的驾车者尤其容易在开车时分神。2009年一份针对大型车辆及卡车驾车者的研究报告指出，开车发短信引发撞车的风险是专心驾驶状态下的23倍。研究人员表示，驾车者开车发短信时，平均每条短信有4.6秒的时间是不看路的，按照每小时车速55英里来计算，相当于一个足球场那么长的距离都是驾车者看着手机在行驶的。而开车打手机同样也有风险，因为驾车者在通话的时候脑子里会想象通话对方的样子，分神自然在所难免。除此之外，现在车内安装的网络浏览器和<span word="GPS">GPS</span>定位仪等高科技设备看似是为车辆行驶安全才增装的，但其实也有让驾车者分神的嫌疑。</p><p><span word="Texting">Texting</span> <span word="and">and</span> <span word="talking">talking</span> <span word="on">on</span> <span word="cell">cell</span> <span word="phones">phones</span> <span word="behind">behind</span> <span word="the">the</span> <span word="wheel">wheel</span> <span word="kills">kills</span> <span word="more">more</span> <span word="than">than</span> 5,000 <span word="people">people</span> <span word="every">every</span> <span word="year">year</span> <span word="on">on</span> <span word="US">US</span> <span word="highways">highways</span>. <span word="Teen">Teen</span> <span word="drivers">drivers</span> <span word="seem">seem</span> <span word="to">to</span> <span word="be">be</span> <span word="especially">especially</span> <span word="susceptible">susceptible</span> <span word="to">to</span> <span word="distraction">distraction</span>, <span word="a">a</span> <span word="study">study</span> <span word="says">says</span>.</p><p><span word="A">A</span> 2009 <span word="study">study</span> <span word="focusing">focusing</span> <span word="on">on</span> <span word="drivers">drivers</span> <span word="of">of</span> <span word="larger">larger</span> <span word="vehicles">vehicles</span> <span word="and">and</span> <span word="trucks">trucks</span> <span word="has">has</span> <span word="concluded">concluded</span> <span word="that">that</span> <span word="texting">texting</span> <span word="raised">raised</span> <span word="the">the</span> <span word="risk">risk</span> <span word="of">of</span> <span word="a">a</span> <span word="crash">crash</span> <span word="by">by</span> 23 <span word="times">times</span> <span word="compared">compared</span> <span word="with">with</span> <span word="non">non</span>-<span word="distracted">distracted</span> <span word="driving">driving</span>, <span word="says">says</span> <span word="an">an</span> <span word="environmental">environmental</span> <span word="report">report</span>.</p><p><span word="Environmental">Environmental</span> <span word="researcher">researcher</span> <span word="Uvid">Uvid</span> <span word="Hosansky">Hosansky</span>, <span word="who">who</span> <span word="authored">authored</span> <span word="the">the</span> <span word="report">report</span> <span word="for">for</span> <span word="the">the</span> <span word="journal">journal</span> <span word="CQ">CQ</span> <span word="Researcher">Researcher</span>, <span word="wrote">wrote</span>, "<span word="Texting">Texting</span> <span word="drivers">drivers</span> <span word="took">took</span> <span word="their">their</span> <span word="eyes">eyes</span> <span word="off">off</span> <span word="the">the</span> <span word="road">road</span> <span word="for">for</span> <span word="each">each</span> <span word="text">text</span> <span word="an">an</span> <span word="average">average</span> <span word="of">of</span> 4.6 <span word="seconds">seconds</span>, <span word="which">which</span> <span word="at">at</span> 55 <span word="mph">mph</span> <span word="means">means</span> <span word="they">they</span> <span word="were">were</span> <span word="driving">driving</span> <span word="the">the</span> <span word="length">length</span> <span word="of">of</span> <span word="a">a</span> <span word="football">football</span> <span word="field">field</span> <span word="without">without</span> <span word="looking">looking</span>."</p>
