Нужно срочно!!!!!!! Task 1. Read the text and add the sentences.
AWORLD OF MUSIC - BUT WHO CHOOSES IT?
Music is all around us. However, we rarely think about who chooses the music, and we've no idea
how they decide what to play. It is a science,' explains Liam Collins, 41, who is DJ at the
Bluewater Shopping Centre in Kent, 1.
We play music in the dining areas,
entrance halls and the country yards, you can hear a whole range of different music, from Paul
Oakenfold mixes to Frank Sinatra. In the morning, the music is generally on loud. 2.
The busier the shopping centre gets, the more relaxing the music needs to be.
People listen more carefully to the music than you might think. Once we accidentally played White
Christmas At Easter. A huge crowd of people came to reception to tell us.' 'I don't actually think the
crowd care about the music, to be honest, 'says Richie Tierney. PA announcer at Prenton Park
football ground, the home of Tranmere Rovers. 3.
. Otherwise, Richie and his
assistant have clear rules. They play James Brown's I Feel Good when Tranmere score and they
play a special re-mix of Going Home by Mark Knopfler when people are leaving the stadium. We
also spoke to several taxi drivers. What is important for them is to have music playing, but what
they actually listen to is nothing like as important as how loudly they play it. We play everything.
No one complains about what it is, but the minute it gets too loud, then people complain.' 'I don't
really care what I listen to,' says Jed Strange, a London cabby. 4.
But I do
change the music if the customer doesn't like it. That way, the tips I get are much better.' he admits.
We also found a taxi driver who only plays classical music. "Classical music is just as enjoyable as
rock,' he says. "With classical music I feel far more relaxed, and I really need that with today's
traffic, which is getting a lot worse every day.' And in that he's not alone - classical music is also
the preferred choice of Dr. Janet Highsmith, a dentist from Cambridge. Most of my patients are
pretty stressed,' she says. 5.
It's usually a piece of Baroque music that helps them
to relax .'
1.
It has more than 27 million visitors spending over $770 million a year.
2.
I just turn on the radio and listen to whatever comes.
3.
You don't want to play rock music and get them even more worked up.
4.
But later on, it's quieter,
5.
But if we've got a big cup match and we play "We will Rock You", they will clap.
