14.Texting(發(fā)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(走路不遵守交通規(guī)則).

分析 本文是一篇議論文.主要講了在走路的時候發(fā)短信,不僅會影響平衡,給自己帶來危險,還會影響其他人,造成交通事故.
解答 答案:CBAD.
28:C.細(xì)節(jié)理解題.根據(jù)"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,一邊走路一邊編輯短信對人們的安全有影響,會使人們置身于危險之中.故C選項正確.
29:B.詞義猜測題.根據(jù)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,這個人徑直走進(jìn)了購物中心的噴泉中,由此可以推知他太專注于自己的手機(jī)以至于沒有注意到危險.故B選項正確.
30:A.推理判斷題.這兩個例子都是為了證明上一句中的…they may not know it has a serious effect on the safety of themselves.Other facts have also proved this:一邊走一邊編輯短信會傷害自己.故A選項正確.
31:D.細(xì)節(jié)理解題.根據(jù)In a pedestrian(步行的)environment,inability to maintain a straight path would be likely to increase potential for traffic accidents可知,邊走邊編輯短信使步行者不能直線行走,增加了他們遭遇交通事故的可能性.故D選項正確.
點評 閱讀理解考查對文章的理解能力,考生首先要仔細(xì)閱讀短文,完整了解信息,結(jié)合上下信息,準(zhǔn)確把握作者觀點,選出正確答案,注意不能以偏概全,張冠李戴.
