Social customs (习俗) and ways of behaving change all the time. Things that were considered

Social customs (习俗) and ways of behaving change all the time. Things that were considered impolite many years ago are now acceptable. Just a few years ago, it was considered to be impolite behavior for a man to smoke on the street. No man who thought of himself as being a gentleman would make a fool of himself by smoking when a lady was in the room.
Customs also differ from country to country. Does a man walk on the left or the right of a woman in your country? Or doesn’t matter? What about table manners (行为)?
The Americans and British people not only speak the same language but also share a large number of social customs. For example, in both America and England, people shake hands when they meet each other for the first time. Also most Englishmen will open a door for a woman or offer their seats to women, and so will most Americans. Promptness (准时) is important both in England and in America. That is, the dinner guest (客人) either arrive close to the time that has been made or calls up to explain his delay (耽误).
The important thing to remember about social customs is not to do anything that might make other people feel uncomfortable —especially if they are your guests. There is an old story about a man who gave a very formal dinner party. When the food was served (服务), one of the guests started to eat his peas with a knife. The other guests were amused or greatly surprised, but the host calmly picked up his knife and began eating in the same way. It would have been bad manners to make his guest feel foolish or uncomfortable.

(答案→)D 解析：【小题1】联系下文by smoking when a lady was in the room.当有女士在房间内时吸烟,可知会让自己看起来像个傻子,故选D【小题1】根据第三段根据That is , if a dinner invitation is for 6 o’clock , the dinner guest either arrives close to that time or calls up to explain his delay.描述，可知应该晚到一两分钟，故选A【小题1】根据It would have been bad manners to make his guest feel foolish or uncomfortable.及本段描述，可知选B【小题1】根据短文开头Social customs (习俗) and ways of behaving change all the time.及下文描述，可知本文主要描述的是社会习惯。故选B
