It is December 25th, 2050. The people in the city are all celebrating Christmas. I'm the mayor of our city. My citizens and I are holding a big party under the sea, though you wouldn't believe it. But please do not feel excited, you should feel sad because we have to live under the sea. Because of the pollution, the earth has been completely destroyed, from top to bottom. The atmosphere has no oxygen and moisture. As a result, the plants are burned by the strong sunlight with a great number of harmful rays. Of course, none of them are still alive. Not only no green, but also the temperature reaches about 121℃ all day even in winter because there is too much CO2 circling the earth.
On the land, there is no life. Luckily, the sea is not destroyed by human. So, we have to move into the sea. At the bottom of the water, people have built many new cities. There is a lot of advanced* equipment in each city. Computers are used to control all the machines, even the people's life. We can also make the seawater into fresh water. There are two machines making oxygen. If they stop working for only one minute, more than 10 million people will die.
The population of our city is over 30 million and, of course, it is quite crowded. We have lots of high buildings and bridges. The roads are wide, too. Our cars are miniature UFOs, don't be surprised, it is true. At the bottom of the sea you can't see anything, because there is no light all day. However, we have advanced lighting equipment so that we can see the "sun"under the sea. Of course, the advanced lighting equipment is very expensive. And if it doesn't work, we can see nothing under the sea. What should we do then?

Language changes all the time. New words and phrases appear and develop. The words and pronunciations used by young people in the UK can be very different to those used by adults. Living in a multicultural (多元文化的) society has an effect on language, especially on young people, whose friends are often from a mix of backgrounds. TV and music also have big influence on the language of the young. Often UK singers sing in American accents (口音) without realizing.

Young British people use lots of language that you usually can't find in most dictionaries. These informal words and expressions are known as ‘slang'. It is not possible to make a complete list of modern British slang. By the time the list was finished, it would be out of date! New words come and go like fashions. However, here are a few examples:

Ø Safe, sorted, sound, cool or wicked all mean "That's good" or "I understand".

Ø  Instead of using different tag questions like … isn't it? can't you? or don't they?,     people use innit.

Ø  Instead of saying very, really or completely, people use well.

Ø  Whatever means I don't care.

Ø ‘He's fine' or ‘He's fit' both mean ‘He's good-looking'. Fine and fit can describe a boy or a girl.

Not everybody uses slang and not everybody likes it. A school in Sheffield, in the north of England, recently stopped its pupils using slang words such as hiya (hello), cheers and ta (both mean thank you). The head teacher says that if young people learn to speak ‘correctly' this will help them get a place at university and a good job.

When British people use language like this, it's no surprise that some students say they can't understand native (本土的) speakers. But perhaps learners don't need to worry about communicating with native speakers so much. Research shows that most of the English spoken in the world today is spoken between non-native speakers of the language. In fact, when we think about "International English", there is no such thing as a native or non-native speaker.

    When you are learning English, listening, speaking and writing are important, but reading can also be very helpful. When you read, you can not only learn some new words, but also you can learn how to use these English words. When you read, it gives you a good example for writing.

    Good reading tips:

    Try to read at the right level(水平). Read something that you can (more or less) understand. If you need to stop every three words to use a dictionary, it is not interesting.

    Try to increase the number of your new words. If there are four or five new words on a page, write them in your notebook. But you don't have to write them while you read. Instead, try to guess their meaning as you read: mark them with a pen. Then come back when you have finished reading to look them up in a dictionary and write them in your own vocabulary book. Then try to remember them.

    Try to read regularly. For example, read for a short time once a day. Fifteen minutes every day is better than two hours every Sunday. Fix(固定) a time to read and keep to it. You could read for fifteen minutes when you go to bed, or when you get up or at lunchtime.

    Read what interests you. Choose a book or a magazine about a subject that you like, because you are going to spend time and money reading it. So, choose an interesting book. You can also read newspapers. There are many English newspapers in China. For example, 21st Century Teens. It is easy enough for you to understand it. There is something interesting in it.
