In England, recently three foreign      came to a bus stop and waited. About five minutes later, the bus they wanted came along. They were just going to get on when suddenly there was a loud noise behind them. People rushed onto the bus and tried to push them out of the way. Someone shouted at them. The bus conductor came rushing down the stairs to see what all the trouble was about. The three foreigners seem all at sea and looked    . No one had told them about the British customs of lining up for a bus that the first person who arrives at the bus stop is  person to get on the bus.
Learning the language of a country isn't enough. If you want to have a pleasant visit, find out as much as possible about the           and customs of your host country. You will probably be surprised just how different they can be from your own. A visitor to India would do well to remember that people there consider it impolite to use the left hand for passing food at table. The left hand is    to be used for washing yourself. Also in India, you might see a man shaking his head at another to show that he doesn't agree. But in many  parts of India a shake of the head means         . Nodding your head when you      a drink in Bulgaria will most probably leave you thirsty.
In that country, you shake your head to mean "yes"-a nod means "no". At a meal in countries on the Arabic Peninsula, you will find that your glass is repeated refilled as       as you drink up . If you think that you have had enough, you should take the cups or glasses in your hand and give it a little shake from side to side or place your hand over the top.
In Europe, it is quite usual to       your legs when you are sitting talking to someone even at an important meeting. Doing this in Thailand, however, could bring about trouble. Also , you should try to avoid(避免) touching the head of          adult---it's just not done in Thailand.
