题文
Turns out we aren’t good at walking and talking at the same time, according to a study of pedestrians （行人） on their cell phones．Nearly one-third of pedestrians （29．8% ） were distracted （分散注意力） by their mobile devices while crossing the street, say researchers of a study published online in the journal Injury Prevention．
Just as drivers who text, talk on cell phones, or adjust MP3 players increase their risk of losing control of their vehicles, pedestrians distracted by their conversations or their devices also put themselves at higher risk of getting into an accident．
During the summer of 2012, scientists in Seattle, Wash． , studied 1,102 pedestrians at 20 crossroads seeing the city * s highest number of pedestrian injuries over the past few years．
They watched how pedestrians crossed the street @ whether they looked both ways or obeyed the crossroad signal @ and also recorded how long it took pedestrians to do so．Distractions included listening to music with headphones, using a cell phone or earpiece to talk on a cell phone, text messaging, and talking with another person．
Overall, researchers found the most common distraction among pedestrians was listening to music （11．2%）, followed by text messaging （7．3%）, and using a handheld phone（6．2%）． But the most absorbing distraction was texting． Compared to pedestrians who were not distracted, those who were texting took 1．87 seconds longer to cross and were four times more likely to not look where they were going, disobey traffic lights, or cross outside of the crosswalk． While the study did not track injuries related to these trends, previous studies have linked such activities to a higher risk of being injured while crossing the street．
Combined with the rise in the use of mobile devices, especially smart phones, the results raise concerns that multi-tasking while walking may be a rising concern for pedestrians． And that danger may only climb, as the number of wireless devices has already exceeded the population of the United States． Last year, roughly 1,152 people wound up in the emergency room to treat injuries caused by using a cell phone or electronic device, the Consumer Product Safety Commission told the Associated Press in July． Those numbers may be underestimated, however, because patients may not always admit that they were using their phones along with other activities such as walking or driving when they were hurt．
小题1:The scientists did their study at the 20 crossroads in order to _____．A．attract more attentionB．see more injuriesC．record more samplesD．find more pedestrians小题2:According to the research, while crossing the street the most dangerous activity for apedestrian is _____．A．talking on a phoneB．texting messagesC．listening to musicD．disobeying traffic lights小题3:The underlined word "exceeded" is closest in meaning to "____"．A．gone beyondB．greatly influencedC．accelerated the increase ofD．drawn the attention of小题4:Which might be the best title of the passage?A．Walk and don't TalkB．Prevention of DistractionC．Look both ways while crossing the streetD．Cell phones lead to injuries 题型：未知 难度：其他题型
答案
小题1:C
小题2:B
小题3:A
小题4:A
解析
文章大意：文章介绍行人在步行的时候会同时打电话，发短信，这些都会带来很多安全隐患，科学家对20个十字路口做研究就是看在过去几年最多的行人受伤的情况，发现过马路的时候发短信是最危险的行为。
小题1:细节题：从第三段的句子;During the summer of 2012, scientists in Seattle, Wash． , studied 1,102 pedestrians at 20 crossroads seeing the city * s highest number of pedestrian injuries over the past few years．可知科学家在20个十字路口做研究就是看在过去几年最多的行人受伤的情况，也就是收集样本，选C
小题2:细节题：从第六段的句子：But the most absorbing distraction was texting． Compared to pedestrians who were not distracted, those who were texting took 1．87 seconds longer to cross and were four times more likely to not look where they were going, disobey traffic lights, or cross outside of the crosswalk．可知过马路发短信花费时间更长，更容易分散注意力，所以过马路的时候发短信是最危险的行为，选B
小题3:猜词题：从最后一段的句子：And that danger may only climb, as the number of wireless devices has already exceeded the population of the United States．可知随着无线设备的数量超出美国的人口，危险的数量还会增加，exceeded="go" beyond，选A
小题4:主旨题：从全篇文章的内容和第一段的句子：Turns out we aren’t good at walking and talking at the same time, according to a study of pedestrians （行人） on their cell phones．可知行人在走路的时候不能交谈，所以标题是：走路的时候不要谈话，选A
