Courtesy, politeness, good manners——call it what you will,the supply never seems to equal the demand.
A、...there is never enough politeness in real life.
B、...the demand to supply equal names is never satisfied.
C、...you can never have enough words to describe politeness.
D、...it is difficult to find a balance between different manners.
【正确答案】：A
【题目解析】：原句译文：礼貌也好，客气，或文明举止也好，无论你称它什么，其供应似乎总是小于需求。supply指的是人们实际表现出来的礼貌(行为),demand是指人们维持和谐关系所需要的礼貌(行为)，因此真正的含义为在现实生活中，人们并没有表现出足够的礼貌来维持相互之间的和谐关系。即A项所表达的含义。答案为A。
