issue 38的思路

bfghdggf

孙元的宝典上的思路是这样的： 1。it is true that some of the traditional forms of courtesy are missing as our society becomes more and more urbanized. 2.however ,we also encounter multiple instances of ordinary courtesy and good manners every day. 3.as the society progress ,new ways to show courtsy are emerging . 大家觉得这些份论点该怎么展开阿，或者谁有更好的论点，请指教！
