Passage 5
"Fingers were made before forks" when a person gives up good manners, puts aside knife and fork, and dives into his food, someone is likely to repeat that saying.
The fork was an ancient agricultural tool, but for centuries no one thought of eating with it. Not until the eleventh century, when a young lady from Constantinpole brought her fork to Italy, did the custom reach Europe.
By the fifteenth century the use of the fork was widespread in Italy. The English explanation was that Italians were averse to rating food touched with fingers, "Seeing all men’s fingers are not alike clean." English travelers kept their friends in stitches while describing this ridiculous Italian custom.
Anyone who used a fork to eat with was laughed at in England for the next hundred years. Men who used forks were thought to be sissies, and women who used them were called show - offs and overnice. Not until the late 1600’

Operatunity
1 Operatunity is a TV talent show for amateur opera singers.The winners get the chance to sing with
the English National Opera. When two housewives,Denise Leigh and Jane Gilchrist won in 2002,their lives
changed forever. As they sang Verdi's Rigoletto at the Coliseum（音乐厅）in Rome, they were transformed
from working mothers into opera celebrities（名人）.
2 "I live in the village I was born in,"says Denise,who is blind."Lots of my neighbours are family,
and my life is all about my three children."Jane,who worked as a cleaner and a shop assistant,was in a similar
situation.She says,"All I had to look forward to was seeing my four children grow up,and I love that,but…
you think'there must be more to life'.Winning Operatunity has opened up avenues I never knew existed."
3 "This last year has been amazing,"Denise continues."Last mouth was Paris,before that we werere--
cording at Abbey Road,in London,and recently we had our album launch at the Royal Opera House."
"We've been treated like princesses,"laughs Jane.“…champagne,chocolates,five-star hotels…”
4 But it wasn't all so easy.For Denise,the worst part was waiting at the beginning."After I'd sent in
my application form I worried for a month. Then I had to wait ten days after my first audition（试唱）.That
was awful."Even when they won the competition they were allowed to tell their close family but they weren't
allowed to tell anyone else until later. Denise and Jane also found the travelling difficult.They couldn't take
their children with them while they were away singing,so they had to organize childcare.However,there's
been no problem with the physical side of singing:"We didn't have to worry about that as we've had lots of
help and wonderful voice training,"says Jane.They also had to learn to deal with the media."The kids loved
the fact that they could stay up and watch us on TV,but I just couldn't understand why some newspapers
were more interested in the fact I divorced at 21,rather than the fact I had just sung at the Coliseum,"says
Denise.
