3．A man looking at his smart-phone while walking across a railway crossing in Nanjing （71）had （have） a close knock on Oct.22．He was so （72）absorbed （absorb） in his smart-phone that he didn't see a train approaching until it brushed past him，（73）throwing （throw） him to the ground．This should serve（74）as a warning that people should be aware of their surroundings，especially （75）when/while crossing roads．
（76）Luckily （lucky），the man survived a brush with death，but the incident forced the driver（77）to stop （stop） the train．An 18-minute delay followed the incident，（78）which led to a break in the running of other trains on the route．
Smart-phone （79）addiction （addicted） has spread like an infectious disease．It's evident that it will do great harm to society．What's even（80）worse （bad），some addicts become impatient with relatives and friends．
Some people blame the smart-phone for the tragedy，yet in fact people's weakening self-control and self-discipline are to blame．
