Traffic safety is everybody's business.Records show that every year a lot of people die in traffic accidents.Some of the accidents are due to mechanical problems.However,most of them are the results of careless and reckless driving,and could be avoided.A lot of people disregard traffic signals and rules.They drive regardless of speed limits,run through red lights,drive in the wrong direction,talk and laugh while driving,and turn as they wish without giving signals.They don't slow down while approaching crossroads.So many people violate traffic regulations that we cannot put too much emphasis on the importance of traffic safety.Only when everybody thinks traffic safety is everybody's business can we be safe driving on roads and walking on sidewalks
蓝牙耳机的话,就要看你老爸的手机是否支持这个蓝牙耳机了,蓝牙耳机应该是那种无线的耳机,不过据我了解应该是每台手机都配有有线耳机的,就是可以一键接电话那种,还不用拿手机出来,有那个耳机就行了,没必要用蓝牙耳机的,车载电话应该算是智能机了,那种也还好啦,看你个人所需,你上百度打车载电话,有详细介绍的,我觉得用手机原配有线耳机挺好也挺方便的,接电话也挺安全的.
