參考答案:

Needless to say,the number of acquaintances increase with one's age.The older one gets,the more place one has traveled,the more work experience one has,and the more acquaintances one is supposed to have.But not all acquaintances are friends.We come to know many people either in the way of business or by mere chance—say,having been at the same table at a dinner party.We may be on nodding or hand-shaking terms,call each other “friend”,sometimes write to each other with the salutation of “Dear So-and-So”,etc.All these are,in fact,nothing but civilities of social lefe,as hypocritical as the polite formula“dunshou”(kowtow)or“baibai”（a hundred greetings）used after the signature in old-fashioned Chinese letter-writing.We may call them social intercourse,far from the genuine friendship.
