     Jamie Oliver has been invited by Gordon Brown to prepare a banquet at No. 10 for President Barack Obama

and other leaders of the G20, offering a cut-price menu to reflect times when trade and industry are far from

prosperous and the rate of employment is de- creasing.

     Downing Street sources say Oliver, the well-known chef, will cook using" honest high-street products" and

avoid expensive or "fancy" ingredients (材料).

     The prime minister is trying to avoid a repeat of the embarrassment last year when he sat down to an

18-course banquet at a Japa nese summit to discuss world food shortages.

be served by appren tices (学徒) from Fifteen, the London restaurant Oliver founded to help train young people

in poverty in order to make a living by mas tering a skill.

     Brown wants the dinner to reflect the emphasis of the London summit, which he hopes will lead to an

agreement to lift the world out of recession." To be invited to cook for such an important group of peoplc,

who are trying to solve some of the world's major prob lems,is really a privilege," said Oliver.

     "I'm hoping the menu I'm working on will show British food and produce is some of the best in the world,

but also show we have pioneered a high-quality apprentice scheme at Fifteen London that is giving young

people a skill to be proud of."

Ministry of Food, which has budget recipes for beef and ale stew (啤酒炖菜) and "im pressive" chocolate

fudge cake.
