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 (付小费) 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.

Dear Mr. Black,
I’m very thank to you for inviting me to stay with you in the come summer vacation. I have been dreamed of seeing you again so that I can get help from you in my English learning. And I’m afraid I cannot go to your place in this summer. I’ve promised my grandmother, she lives in the country, to spend this summer with her. She misses me too much that I find difficult to refuse her request. I’m busy preparing for my examinations in present. I planned to visit you in winter if it’s convenient to you.
