    It is interested to visit another country, but sometimes there are some questions when we don't know the

language very well. It may be difficult to talk about the people there. We may not know how to use the

telephone in the country which are visiting. We may not know what to buy the things we need. In a strange

country we may not know where to eat and what to order in a restaurant. It is not easy to decide how many

money to tip (小费) waiters or taxi drivers. When we are helpful, we may not know how to ask help. After

a short time later, however, we learn what to do and what to say. We learn to enjoy life in another country,

and then we may be sorry to leave both the place and the people.
