we often see some people breaking rules of etiquette on the bus.what suggestions we can give them ?
sometimes,the people on the bus drop litter everywhere. When it happens,we could say,"Please don't do that."And while someone is smoking on the bus,we can say,"sorry,could you please put out your cigarette?" Spitting is such an impolite behavior that we must stop them. we may say to the person,"Would you like not to spit in public?" Of course,some people like talking or laughing loudly with their friends on the bus.If that happens,we could say,"It's better to keep quiet,do you think so?"

注意大写字母，我改了很多地方如：such...that,an impolite,为了避免句式重复，也改了一些，尤其是should全改了其他的情态动词，显得语气更委婉。well done.

我记得would是情态动词，后面应该加动词原形。所以，应该是"Would you not do that?"
还有一些拼错的单词，我也改了一下。
