Mobile phones bring us a lot of convenience.However,as is shown in a survey of social practice in summer vacation,an increasing number of people use mobile phones in improper situations,such as driving cars,crossing the roads or attending conferences.Such inappropriate behavior is likely to bring bad consequences.On one hand,using mobile phones this way may cause terrible accidents,which is really dangerous.On the other hand,talking loudly on the phone in public places is far from being polite.
Personally,I think we shouldn’t use mobile phones where attention or silence is needed,for instance,in libraries,hospitals,or in a plane.Besides,relevant laws are supposed to be passed in order to guide people’s use of cellphones so that they will acquire good habits in public.Only when everybody has the awareness of the negative impacts of improper use of phones can we create a more civilized society.
