We know good manners are important. Today I am going to tell you something about manners in different countries. I think you already know that people in different countries usually have different ways of doing things. ①Something that is rude in one country may be quite         in    

      . ②For example, in Britain you mustn’t raise your bowl to your mouth when you are having soup. That is considered bad manners in Britain. But in Japan you needn’t worry about making noise when you drink something. It shows that you are enjoying it. In Britain we try not to put our hands on the table at all during a meal. ③Guests are expected to keep their hands on the table during a meal in Mexico. In Arabic countries, we must be careful with our hands. You see, in Arabic countries you mustn’t eat with your left hand. This is considered to be very impolite. So, what should you do if you visit a foreign country? Well, you needn’t worry. You can ask the native people there to help you and you can just watch carefully and try to do what they do.
