Question

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.

【解析】

试题分析：短信是人们平时交流的方式，但是走路的时候发短信，这往往会带来一系列交通安全问题。所以有些国家为了避免安全事故的发生，而就走路发短信进行了立法。

1.C细节理解题。由第二段中的“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。

2.

3．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。

3.D细节理解题。由第四段中的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。

4.

猜测词义题。阅读材料中的每个词与它前后的词语或句子甚至段落都有联系。我们可以利用语境（各种已知信息）推测、判断某些生词的词义。做这种类型的题，要根据词、词组、句子所在的语境来判断其意义。因此熟练掌握一些猜词技巧是做好这类题的关键。命题者在出这类题时惯用常规词义来麻痹考生，我们要特别注意熟词生义，切不可脱离语境想当然。在句子或段落中，我们可以利用熟悉的词语，根据语言环境所表示的关系推断生词词义。5. 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。
