smoking
    Although smoling is not allowed on high-speed trains,some smokers violated this regulation and they received punishment.Their bad behaviours cause train delay and set off the fire alarm on bullet trains.
     Smoking,no matter on high-speed trains or other public occasions will definetely affect others and public safety.It is common to hear that cigarette smoking sometimes arouses a big forest fire in autumn.Moreover, second-hand smoking does great damage to one’s health.Some people might get cancer because of second-hand smoking.
     From my perspective,I am against to smoke in public.I view it a lack of moral to smoke in public.First of all,the smell of cigarettes is unbearable.It is so disgusting to find someone smoke in front of me.Also,smoking can cause serious problem.Once,there was a smoker entering the lift.I stared at the man agarily,but he did not pay any attention.In the end,I could not bear it,so I shouted:”No smoking!”The man,however,just ignored me.Suddenly, the man’s action resulted in an emergency braking.The lift stopped and we were trapped in the lift for an hour.
     In a word,smoking is not healthful to smokers and also not healthful to others.So, please do not smke in public.
