GAME SHOWS
Game shows are very popular television programmes. One famous British show is "Who wants to be
a Millionaire?" On the show, people answer questions. The questions are easy at first, but they become
more difficult. Between 1998 and 2008, fifteen players won the top prize of £1,000,000! People also
played this show in many countries, such as the USA. South Africa and Japan.
The first ever TV game show was in 1938. It was a British show called "Spelling Bee". The presenter
was a man called Freddie Grisewood. He had short, dark hair and glasses Freddie asked people on the
show to spell words. The show wasn't very exciting because the game was really easy!
In many modern game shows, like "The X Factor"people try to win prizes and become famous by
singing. The musician Noemi didn't win first prize on the Italian version of the show. But her music
became very popular! Noemi is slim, with long, brown hair. She first appeared on TV when she was a
baby!
1. More than twenty people won a million pounds in a British game show
2. Spelling Bee is older than "Who wants to be a Millionaire?"
3. Spelling Bee was quite difficult.
4. Noemi won "The X Factor" in Italy
5. When Noemi was very young, she was on TV. пж помогите соч!​​
