Do you like shopping? Here are some shopping tips for you.

    First, you should write down all the things you want to buy. You should know how much money you need and take enough money with you. People can bring their own shopping bags now so you needn't buy one from the shop.

    Second, it's very important not to buy the things you needn't. There are many nice things in the shopping mall, but what you need is only some of them.

    Third, when you are shopping , you need to go into different shops and compare(对比)things of the same kind. It may take you lots of time to get the best one.

    Fourth, you can go shopping at the weekend or during holidays. On one hand, there are lots of discounts(折扣) on many things. On the other hand, people have enough time to decide which to buy.

    American schools are quite different from those in China. In America, at the beginning of the term, students must select (挑选) their subjects and teachers first.

    Selecting is very important for your marks in America. So at the first term, don't select too many subjects, or you'll feel very nervous and tired. Then you have to ask for some teaching plans. There is some information about subjects, time arranging, marks and textbooks. At the same time, you must choose the teachers. Different teachers have different teaching methods. If the teacher is called "killer" by the last grade, many students will give up choosing him, because this kind of teacher will leave too much homework, too many exams and give too low grades. There is another thing after you select the subjects and teachers. How to buy textbooks makes each student feel hard. The textbooks in America are very expensive. Each one is about $30—50. In order to save money, many students buy some used textbooks, and some students usually borrow textbooks from the school library.

    In class, discussing is very important. The teacher encourages you to ask questions or show your own opinions. They don't usually ask you to sit well. Instead they allow you to sit or stand anywhere you like.

    What foods are successful? Hamburgers and pizzas are popular. But instant noodles(方便面) have also become a world success. Now instant noodles are celebrating their 61^st birthday!

    Instant noodles were invented by a Japanese named Momofuku Ando. To find a way to make noodles last longer, Ando began experimenting(实验) in 1955 and three years later, he made the first bag of instant noodles. Now, 61 years on, they're eaten all over the world. In fact, they're so popular that Japanese consider instant noodles as their best invention!

    Each year, 95 billion packets of instant noodles are eaten around the world. In the UK, people call instant noodles "pot noodles". University students like them a lot. During the first term at college, you may be given a gift bag that includes instant noodles. Instant noodles are cheap and easy to eat. But watch out! People may think you are lazy if you are an instant noodle lover.

    The UN often sends instant noodles as part of its food aid. This is because of their long life and high fat, which makes people feel full for longer time.

    However, instant noodles aren't totally innocent(无辜的). They are high in fat and salt. Health experts say they are bad for us and we shouldn't eat them too often.

    Tokyo may be one of those places that you love and hate at the same time. In Tokyo, there are always too many people in the places where you want to go. There are also too many cars. Tokyo drivers often spend a long time in the busy street, just like drivers in London, Paris and New York.

    Tokyo also has a lot of people on foot, and sometimes it is really difficult to walk in the street. The worst time in the street is at 11：30 at night. That is because the nightclubs are closing at that time and everybody wants to go home then. There are more than 30,000 nightclubs in Tokyo, and usually none of them is empty at night.

    During the day, most people go to work by train. Six million train tickets are sold, every year in Tokyo. At most stations, trains arrive every two or three minutes, but at certain hours they are not enough at all. Although trains are always crowded, they are very good in many ways. They always leave and arrive on time. In London trains, you may see everybody reading a newspaper. But in Tokyo trains, everybody seems to be sleepy, no matter whether his journey is long or short. If you stand outside the station for five minutes, there will be three fire engineer going past you. They are on the way to one of the fires that Tokyo has every day. Tokyo has so many surprises that none of them can really surprise me now.
