Social customs and ways of behaving change．Things which were considered impolite many years ago are now acceptable．Just a few years ago,it was considered impolite behaviour 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 a room. Customs are also different from country to country．Does a man walk on the left or the right of a woman in your country?Or doesn't it matter?What about table manner?Should you use both hands when you are eating? The Americans and the British 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 seat to a woman,and so will most Americans．Promptness is important both in England and in America．That is,if a dinner invitation is for 7 o'clock,the dinner guest either arrives close to that time or calls up to explain his delay. 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 dinner party．When the food was served,one of the guests started to eat his peas with a knife．The other guests were amused or shocked,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. Bad mannersin the last sentence means__.
A、ugly
B、dishonest
C、impolite
D、shameful
【正确答案】：C
【题目解析】：在给出的段落中，描述了一个人举办晚宴时遇到的一个社交场景。当食物上桌时，其中一位客人开始用刀吃豌豆，这显然不是一种常规的用餐方式，但主人为了不让客人感到尴尬或不舒服，也拿起了刀以同样的方式开始吃。这里的重点是强调在社交场合中，不要做出可能让他人感到不舒服的行为，特别是当他们是你的客人时。 现在来看选项： A. ugly（丑陋的）：这个选项与描述中的社交礼仪无关。 B. dishonest（不诚实的）：文中没有提到任何不诚实的行为。 C. impolite（不礼貌的）：这与文中描述的“不礼貌”的行为（用刀吃豌豆）和主人避免让客人感到“不礼貌”相符。 D. shameful（可耻的）：这个选项过于强烈，与文中的描述不符。 因此，结合上下文，可以判断“Bad manners”在这里指的是“不礼貌的”，所以正确答案是C。
