People in different countries have different ways of doing things. Something is 1 in one country, but it may be quite impolite in another. In Britain, you mustn't lift your bowl to your 2 when you are having some liquid (液体的) food. But it's 3 in China. And in Japan you even needn't worry about making 4 while you are having it. It shows that you're enjoying it. But people in Britain think it's bad manners. If you are a visitor in Mongolia, what manners do they wish 5 to have? They wish you to have a loud "burp (打嗝)" 6 you finish eating. Burping shows that you like the food.
In Britain, you should try not to 7 your hands on the table when you're having a meal. But in Arab countries you must be very careful with your hands. You 8 eat with your left hand. Arabs consider it very 9 manners eating with left hands.
So when you are in other countries, 10 the other people carefully and follow them. As the saying goes, "When in Rome, do as the Romans do."
