根据短文理解，选择正确答案。

    A Christmas Carol was written by Charles Dickens. The first 6,000 copies of the book were sold out in a week. And the book has inspired many plays and movies. The first play was put on in 1844. The first two movies were silent films made in 1901 and 1908. Since then, the story has been remade more than 60 times for television and cinema. What makes such a tale so attractive? Audiences have always loved a good plot, a villain(反面人物) who harms other people or breaks the law, and the ending of right over wrong. The book offers all three.

    The book tells the story of a man named Ebenezer Scrooge. He is mean and cruel to his clerk and turns away（避免）his only living relative. One night, Scrooge is visited by three spirits（幽灵）. The first shows scenes from Scrooge's youth that led to this present state. The second takes him to the homes of his clerk and his nephew. Here Scrooge sees that people can be happy without lots of money. The spirit also shows him the desperate(绝望的） poor people of London. The third spirit shows Scrooge will die alone, and no one will care if he continues to live as he has. At last the message is understood, and Scrooge repents. He becomes generous and caring to all around him, especially to his clerk's sick son, Tiny Tim.

    Every year, thousands of people watch A Christmas Carol. Why? They may be touched by its lessons on the true meanings of wealth and happiness. They may enjoy the special effects and feelings or watching every year may be just a habit. Viewers never seem to grow tired of the old miser(守财奴), Scrooge, and his dramatic message of hope and change.

    In the eyes of many foreigners, Chinese are the best hosts (主人) and the worst guests in the world. They're not really bad guests, but because the guest-host relationship in China is much different than in some western counties, it appears they are not nice guests. And western guests sometimes look rude (粗鲁的) 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 non-smoker, 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 America 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 don't allow you to smoke in their house, they are not a rude guest.

    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 home, don't be too surprised if they don't bring you a gift.

    In China, you probably won't need to change the guest-host 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.

    ①When it comes to Chinese students thinking about studying in foreign countries, many of them usually believe that life will be easy and enjoyable. Unluckily, it seems that students with those beliefs will be disappointed very soon after landing at the airport.

    ②So, what are the problems you may have, and how can you deal with them?

    ③Teaching and learning styles in America are very different from those in China, in need of more critical thinking（批判性思维）and teamwork. In most American classrooms, they do activities in a study group in which every person has their own responsibility(责任).

    ④So don't worry about your language or any grammar mistakes. Just watch what other students do, and don't be afraid to ask any questions. The discussions, or sometimes even arguments, that your group members and you hold, are probably to be the beginning of a friendship.

    ⑤Besides schoolwork, another important thing faced by overseas students is homesickness or loneliness. You may miss your parents cooking, your pets, or even your old bed. Being away from home can create bad feelings, especially when faced with the problems of getting used to a new environment.

    ⑥What I strongly suggest is to try hard to deal with these feelings. Be open to new friend-ships. Be active in school activities, and allow yourself to enjoy life at school, even if you miss home a lot. Keep a diary to check your progress. Write down three new things that you're thankful for every evening, as well as three things you're looking forward to every morning.

    ⑦Studying aboard is never simple. In fact, there will be many difficulties every day. But I'm sure you will overcome your difficulties and make your time overseas a success.

    Different gestures (手势)mean different things in different countries. Sometimes a gesture that is polite in one country is not polite in another and should not be used. Different meanings of gestures can also cause problems in understanding what another person is trying to say. A gesture that many people do not understand is one that uses the thumb. Most westerners will sometimes show that they like something by holding out a closed hand with the thumb lifting in the air. This is called give someone or something "the thumbs up". Often, only one thumb is used, so it should be "the thumb up".

    The usual explanation (解释)for the origin of this gesture is not really correct. It says that in ancient Roman times, when people were pleased with the way a gladiator (角斗士) had fought, they showed their thumbs up. When they were not pleased, they gave the thumbs down. When a gladiator was given the thumbs up, the emperor allowed him to live. When a gladiator was given the thumbs down, the emperor ordered him to be killed.

    The truth is, however, it was translated into a wrong meaning by mistake. If people wanted to save the gladiator, they put out their hands and hid their thumbs in their hands. If they wanted the gladiator to die, they pointed their thumbs straight at him.
