Dear Mike，

      I'm so glad you're coming to China! Your mother，our foreign English teacher，told me you're worried about what you should and shouldn't do as a guest in China．Here's some advice．You will probably be invited to a big meal. You may find it earlier than you expect because Chinese people eat dinner much earlier than people in the West．There will be a lot of different dishes，not just three courses．You may find it difficult to use chopsticks if you haven't tried before．It's a good idea to get some practice．When the food is served，you should take time to look at it. The preparation takes a long time and everything will look beautiful．The plates will be placed in the middle of the table，for everyone to share．Take a little of everything and then have some more of the things you like．Chinese people like to talk about food，so it's a good topic of conversation．At the end of the meal，you will usually be served with fruit．Eat your fruit，thank your friends， and go．

      I hope this is helpful．E-mail me if you have any other questions． 

                                                                                                                              Yours，

                                                                                                                                   David Zhang

    The annual English Festival, which was lasted one week, has just ended. There were all kinds of colorful activities, included an English speech competition. Last Friday, we had an honor of inviting Professor Smith to deliver a lecture on English cultural background information, such as English idiom. He was very learned and humorous that he began his lecture with an amusing story to attract the attention of the audience and all of us was deeply impressed with his wisdom. We admired him and took notes carefully, for he made himself understood with speaking slowly and clearly enough for us to follow her. He gave us some practically ways to develop the sense of language and encouraged us to keep speaking English as much possible in our daily life.
