作为一个有礼貌的人应该做到，从来不在别人危急的时候讥笑他，相反却去帮助他。办事的`时候要说“请”，“谢谢”。
在公共场合不要大声喧哗。当你打喷嚏时或吐痰时要用手帕。
作为一名学生上课不要迟到。如果迟到了，要向老师道歉。
以上述文字为说明，写一篇与礼貌有关的英语作文，在文中需使用打喷嚏(sneeze) ;吐痰(spit)等词汇。
《礼貌》范文如下：
manners are important to happy relations among people. no one likes a person with bad manners. a person with good manners never laughs at people when they are in trouble.
instead， he tries to offer help. when he asks for something， he says “please” and when he receives something， he always says “thanks”。
he does not interrupt other people when they are talking. he does not talk loudly or laugh loudly in public.
when he sneezes or spits， he uses a handkerchief. as a sutdent， it is a bad manner to come late to class. if you are late you should say “i'm sorry.” to the teacher at the time or after class.
