Article: In Britain you may often hear "Drop in any time" or "Come to see me soon", but you can't really do that. People just say those things to make you feel welcome. It is better to telephone before visiting someone at home. If you receive a written invitation to an event that says "RSVP", you should reply to let the person who sent the invitation know whether or not you plan to go. You should never accept an invitation unless you really plan to go. You may refuse by saying "Thank you for inviting me, but I will not be able to come. " If, after accepting, you are unable to go, be sure to tell those who are expecting you as soon as possible that you will not be there. Although it is not necessarily expected that you give a gift to your host, it is considered polite to do so, especially if you have been invited for a meal. Flowers, chocolate, or a small gift are all appropriate. A thank-you note or telephone call after the visit is also considered polite and is an appropriate way to express your appreciation for the invitation. Question: What can you do when a British friend says " Drop in any time"? Yes or no, is the answer "Telephone him or her before visiting."?

Article: Last Friday a storm swept through two villages in the New Territories , destroying fourteen homes. Seven others were so badly destroyed that their owners had to leave them, and fifteen others had broken windows or broken roofs. One person was killed, several were badly hurt and taken to hospital, and a number of other people received smaller hurt. Altogether over two hundred people were homeless after the storm. A farmer, Mr. Tan, said that the storm began early in the morning and lasted for over an hour. "I was eating with my wife and children," he said, "when we heard a loud noise. A few minutes later our house fell down on top of us. We tried our best to climb out but then I saw that one of my children was missing. I went back inside and found him safe but very frightened." Mrs. Woo Mei Fong said that her husband had just left for work when she felt that her house was moving. She ran outside at once with her children.
