1. Money can buy happiness — but only if you are richer than your neighbours. Sociologists
found that it was not quite true to say that being wealthy will not make a person happy, according to today’s research. But it depends on a person’s ability not to live worse than his or
her neighbour. Researchers in the US are sure that most of people are in a non-stop wealth
race with their neighbours

2. A lot of young Britons go travelling thanks to the films they
watch or books they read. A research has shown that as many
as 45 per cent of 16- to 24-year-olds say that fiction greatly
influences their choice of holiday places. For instance, New
Zealand has had a big rise in tourism from the UK since the
first of the Lord of the Rings trilogy. It is clear that more and
more young people wish to visit the parts of the world which
have been made famous by writers and film directors.

3. James Blunt has been nominated the best male singer and
songwriter. His way to success hasn’t been easy. He was born
into a military family, became a pilot at the age of 16 and
joined the army. Finally he found himself in a studio in Los
Angeles, where he recorded his multimillion selling album
“Back to Bedlam”. James draws his personal lyrics from his
life, making them touching and honest

4. Jem, the best female singer, is from Wales, Great Britain,
but became a success in the US before her home country. Her
debut album went straight to the top of the charts, her name
appeared in lots of newspapers. She seems to be a sweet and
easy-going girl but at the same time she is very strong and fairly ambitious. With both the US and the UK at her feet, she is
going to be a megastar

5. You can be a Japanese manager on business in Brazil,
a Mexican computer scientist at a conference in India, or
a Norwegian tourist in an Italian street market, there is one
thing you are likely to have in common — you are probably
speaking English.
“There’s never before been a language that’s been spoken by
more people as a second than a first language,” says Englishlanguage expert David Crystal, author of English as a Global
Language.

6. Britain has a growing English Language Teaching industry. They say that by 2020 it will
be the UK’s biggest export, giving the income of 20 billion pounds a year.
One of the fastest growing markets is China. Though Chinese is the world’s top language as it
has the largest number of native speakers, the Chinese themselves want to learn English. Li
Yang, an ex-newsreader even developed a new method of teaching it. The language is taught
in big stadiums to classes of thousands
