The first part of a new science-fiction series （系列剧）was shown on NBC last night. Star Trek is about a spacecraft（宇宙飞船）which travels faster than the speed of light. The show is developed from three ideas about the 22nd century. First, we'll find other life forms great tools which will make amazing things possible.

  Let's think about these predictions. If we find life forms on other planets, will they be intelligent? I hope so. But we human beings might not be friendly – I don't think we'll believe in the idea of peace one hundred years from now. But this is science fiction, so we can be optimistic! And Star Trek's idea of life in the future is "communicators". And we will be ablt to have conversatins with people who are on because you'll have an electronic notebook. And if you get ill, the doctor won't have to examine you – a machine will "read" your body.  The strangest manchine includes a "teleport" which will take people to a different placein a second!

 The ideas are interesting, and in my opinion there's only one problem with star trek: the acting. The TV company （公司）will have to get better actors. If they do that, the show might be a success. If the acting doesn't improve, Star Trek won't last for more than one series. Of course, my prediction may be wrong. I can't see into the future!

    Good morning. The program today is about music. The word "music" comes from the Greek word "muse". The Muses are the goddesses of the arts. The Music is only one of the arts. It is like the spoken language, but it uses sounds. Today's program brings together music from different concerts of the world. Who invented music? Who sang the first song? No one knows exactly the answers to these questions. But we know that music plays an important part in almost everyone's life. Babies and young children love to hear people singing to them. When they are a little older, they like to sing the songs they have heard. When children go to school, their world of music grows. In the middle grades, students take music lessons. When they reach high school, they become interested in listening to pop music.

    The records we have chosen for you today are from American country music, Indian music, pop music and so on. Music has meaning for everyone. It can make people happy or it can make them sad. In this program we shall study the language of music. We shall be trying to find out more about how music works. We shall try to find out how music says what people feel.

    Now, here comes the music today, I shall explain why they are all good music.

    In the eyes of many foreigners, Chinese are the best hosts and the worst guests in the world. They're not really bad guests, but because the guest­host relationship in China is much different than in some Western countries, it appears they are not nice guests. And Western hosts sometimes look rude in the eyes of Chinese guests.

In China, guests are almost like gods. Whenever I enter a Chinese person's home, there is always fruit on the table for me, and someone is quick to bring me a cup of tea or water. In the West, generally the guest is not a god. Acting according to the host's way of doing things is usual behavior for a guest.

    My wife's mother, a very kind elderly Chinese lady, doesn't smoke. When I see some of her guests smoking in her house, as a non­smoker, I feel unhappy. Usually I want to stop them directly, but I must realize that in China, to be a good host, she must not do that. In most North American homes, if you are a guest, and the hosts are not smokers, you should not smoke in their house. At the very least, you could ask, "Is it OK if I smoke?" But, don't be surprised if they say, "No, you can't smoke." In our culture, if you smoke in their home, you are a bad guest, but if they do not allow you to smoke in their house, they are not a rude host.

    Guests in China also have special habits. Some Western people may not adapt to these habits very soon. Thankfully my wife is Chinese, so whenever we visit a Chinese family she tells me to buy them a gift. However, giving a gift to a host is not always necessary in my country. So, if you invite international guests to your house, don't be too surprised if they don't bring you a gift.

    In China, you probably won't need to change the guest­host relationship very much because you will probably only be the host, and Chinese are naturally very good hosts. If Western hosts invite you to their house, try not to be too surprised if their style of treating you is not what you have expected.
