17．Some good manners in modern life
Do you often use a cell phone？Do you take the subway to school every day？These items make our modern life easier．But do you know how we should behave properly while using them？The following suggestions might be helpful．
For cell phone users
◆Keep your voice down when you make a phone call in public．Shouting on the phone may make others feel uncomfortable．And you'd better not use it during a meeting．
◆Don't send messages at a dinner or a party．You shouldn't play cell phone games either．It's a good time to communicate with your family and friends．
◆Don't make or answer a call while driving．It is not only very dangerous for both you and your passen gers but also against the law．
For subway（地铁） passengers
◆You are supposed to wait in a line while buying tickets and getting on the subway．
◆According to subway rules，you mustn't eat，drink or smoke on the subway．The smell and noise may trouble others．It's necessary to keep the train clean and tidy．Besides，smoking is bad for your health and harms people around you．
◆You'd better not lie across the subway seats even if th e train isn't crowded．Offering your seat to someone who needs it is considered as good manners．
