14．Texting（发短信）walkers aren't just an annoyance to other walkers，Australian researchers armed with movie special-effects technology have determined scientifically that they're threats to themselves．Using motion-capture technology similar to that used for films，researchers concluded that texting while walking not only affects balance but also the ability to walk in straight line．"Some people like checking emails while walking to work in the morning"said the study co-author Hoorn，"but they may not know it has a serious effect on the safety of themselves"．Other facts have also proved this．A tourist from Taiwan walked off a pier near Melbourne last month while checking Facebook，bringing a sudden and icy end to a penguin-watching visit．Another person who was too wrapped up in his phone to notice dangers walked straight into the fountain in front of a shopping mall．
The Australian study involved 27 volunteers，a third of whom admitted having knocked into objects while texting．They were asked to walk 8.5 meters three times-once without phones，once while reading text and once while writing text，when eight cameras recorded their actions．
They found the volunteers using the phone walked slower，and，more seriously，they locked their arms and elbows in like"robots"，which forced their heads to move more，throwing themselves off balance．"In a pedestrian（步行的）environment，inability to maintain a straight path would be likely to increase potential for traffic accidents"，said Mr．Hoorn．"The best thing to do is to step aside and stop，or keep off the phone．"
Authorities world-wide have taken note．Signs on Hong Kong's subway system advise passengers in three languages to keep their eyes off their phones．Police and transport authorities have highlighted the danger in Singapore，where the Straits Times newspaper recently declared cellphone-distracted road crossing as"bad habit No.2"contributing to the rising number of road deaths．Some U．S．states，including New York and Arkansas，are considering bans on what they're calling phone jaywalking（走路不遵守交通规则）．

分析 本文是一篇议论文．主要讲了在走路的时候发短信，不仅会影响平衡，给自己带来危险，还会影响其他人，造成交通事故．
解答 答案：CBAD．
28：C．细节理解题．根据"Some people like checking emails while walking to work in the morning"said the study co-author Hoorn，"but they may not know it has a serious effect on the safety of themselves"．Other facts have also proved this可知，一边走路一边编辑短信对人们的安全有影响，会使人们置身于危险之中．故C选项正确．
29：B．词义猜测题．根据Another person who was too wrapped up in his phone to notice dangers walked straight into the fountain in front of a shopping mall可知，这个人径直走进了购物中心的喷泉中，由此可以推知他太专注于自己的手机以至于没有注意到危险．故B选项正确．
30：A．推理判断题．这两个例子都是为了证明上一句中的…they may not know it has a serious effect on the safety of themselves．Other facts have also proved this：一边走一边编辑短信会伤害自己．故A选项正确．
31：D．细节理解题．根据In a pedestrian（步行的）environment，inability to maintain a straight path would be likely to increase potential for traffic accidents可知，边走边编辑短信使步行者不能直线行走，增加了他们遭遇交通事故的可能性．故D选项正确．
