阅读短文，选择答案。

     When we get help from others, we say "Thank you". So "Thank you" is very popular among us Chinese

  students. But is it as popular in the UK?

     The answer is "no". Here is a recent survey in the newspaper. "Thank you" is only the 20th most

 popular way of showing gratitude (感激) in the UK.

     The survey shows that British people like "Cheers" most. 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". "Cheers" also means

  "ganbei" in Chinese.

     You may often hear the word between two good friends. "Great", "nice one" and "all right" are also

 popular ways of showing gratitude.

     Of course, there are some formal (正式的) ways to say "thanks" among British people. For example, 

 when a stranger is especially helpful, they may say "brilliant" or "much appreciated (感谢)" to show their

 gratitude.

     By the way, British people usually like to say: "You're welcome", "No problem" or "Sure" to answer "

 thank you".

     So why not try some of them to show your thanks. It could be cool!
