阅读理解 People should have good manners．But what is meant by good manners? This is quite a difficult question to answer．Because sometimes good manners in one place are bad manners in another places． Suppose you are a visitor in the land of Mongolia(蒙古)．Some friends ask you to eat with them．What kind of manners do they want you to have? They want you to give a loud“burp(打嗝)”after you finish eating．Burping would show that you liked their food． In some countries, if you give a loud burp, you are told to say“excuse me, please．”In many places people like to eat together．But in some parts of Polynesia(伯利尼西亚)it is bad manners to be seen eating at all．People show their good manners by turning their backs on others while they eat． What are good manners like in an East African town? The people try not to see you for being polite．You may see a friend, but he may not see you at all．If you're polite, you' d better sit down beside him and wait until he finishes what he is doing．Then he will talk to you． Suppose you visit a friend in Arabia(阿拉伯)．You should walk behind the other tents until you come to his tent．If you pass in front of the other tents, you will be asked into each one．The people will ask you to eat with them, and it is bad manners if you say no． Manners are different all over the world．But it is good to know that all manners begin in the same way．People needed ways to show that they wanted to be friends． |
