     Every day, 340 million people speak it. One billion people are learning it and it is said that by 2050, half

of the world's population will be using it. What are we talking about? That global language-English.

     The English language started in Britain in the 5th century. It is a mixed language. It was built up when

German, Scandinavian and French invaders settled in England and created a common language for

communication.

     Today it is the official language of the UK, the USA, Australia, New Zealand, Canada, South Africa and

Ireland as well as many islands in the Caribbean Many other countries and regions use it for politics and

business, for example, India, Pakistan, Nigeria and the Philippines. English is also one of the official languages

of Hong Kong.

     But global advertising and pop music mean that in most countries, you will see or hear some English.

Thanks to McDonald's, we all know about "burgers", "fries" and "milkshakes". Songs by Madonna, Britney

Spears and Celine Dion are in English. We can sing along, even if we do not understand what we are singing!

     English is a messy (杂乱的) language. Every year, dictionaries include new words that talk about popular

culture, for example, computer-related words such as "blogging", "download" and "chat room". Also included

are words that teenagers use. Who does not know "cool", "OK" or "hello"?

     Other languages also influence English. Many English words come from French. Words like "cafe" and

expressions like "c'est la vie" (that is life) are all part of the English language. On the other hand, the French

language includes English words like "le weekend" and "le camping". German words are also part of English.

Words like "kindergarten" come from the German language.

language in India.
