It's March, 2050.

   Frank and Mary Smith wake up in their comfortable house in the morning and switch on the bedroom computer to get the latest news. They used to read the Times, but changed to electronic newspapers many years ago.
   There is the usual news about space: another space flight has returned from Mars and scientists have discovered a new planet. Then they turn to business news: the US dollar has risen greatly in Shanghai, one of the world's leading business centres. Mary tells the computer to buy 5,000 dollars, and there is a quick response that it has been done.
   As they watch the screen, Mary orders one of the household robots to make coffee for them.

   Frank disappears into the study to join a video conference with his partners around the world. He is a computer engineer, working for several companies. This is his third job: he used to be in marketing and then television.
   Mary has a quick look at the shopping channels - the usual selection of electric cars, household robots and cheap travel offers - before picking up the video phone to talk to her assistant. She also has a job and she is doing medical research. Both she and Frank used to have an office desk in London, but in 2014 they decided to move to the seaside and work from home.
   Frank and Mary have one daughter, Louise, who also has her own workstation at home. She goes to school only one day a week, mainly to play with other students. Classrooms disappeared in 2030 because there was no longer any need for them: communications systems have made it much easier to learn at home.
   Louise, now thirteen, is studying Chinese at present, which has become a world language as important as English. Louise has many Chinese friends. They communicate by computer.
   According to the family doctor, Louise will live to at least 130. Her wish is to work for a few decades (十年) and then spend her time on music and painting.

    “Thank you” is one of the first few phrases(短语） that our English teacher taught us when we began to learn English. Each time we receive help from others, we say “Thank you”. We may say it many times a day. It seems that “Thank you” is very popular among us Chinese students. But is it as popular in the UK?

    The answer is “no”. According to a recent survey （最近的报告）in the Daily Telegraph newspaper, “Thank you” is only the 20^th most popular way of expressing gratitude（感激） in the UK.

    The survey shows that British people like “Cheers” most to express their thanks. For example, when friends invite each other for a drink after a game, a smile and a “Cheers” may be the best way to say “thanks”.

    You may often hear the word spoken between two good friends. “Great”, “nice one” and “all right” are also popular informal（不正式的） ways of showing gratitude among friends in the UK.

    Of course, there are some formal ways to say “thanks” among British people. For example, when a stranger is especially helpful, they may say “brilliant” or “much appreciated” to express their gratitude.

    By the way, how do British people usually answer “thank you”? They like to say： “ You're welcome.”, “No problem” or “Sure”.

    Since you have many more ways to show your thanks, next time you want to say “thank you”, why not try one of these new British phrases?

    English words like other languages change all the time. People need new words for new ideas and inventions. Different words come into use and older words are used in a new way. Here are some ways to change.

    English words can change by borrowing words from other languages. The word “tomato” was from Mexico, and “tea” came from China. Now new words are made by joining two words together. “Weekend” and “cookbook” are examples. A latest one “brunch” comes from breakfast and lunch. Do you have brunch every day? Sometimes new words are shorter forms (形式) of the longer words. For example, the word “photo” was from “photograph” by cutting off the end of the longer words. “Plane” and “phone” were made by cutting off the front part of “airplane” and “telephone”. The names of people and products(产品)can also become new words. Our food “sandwich” was from a man called Sandwich.

    Can you find any other examples for each of these ways to make new words?
