     An independent college claimed to have become the first school in England to make Chinese a compulsory

(强制的) subject for its pupils.

     Richard Cairns, the headmaster of Brighton College, said the move aims to recognize the importance of

China as the world's fastest growing economy.

     Chinese will become one of the core subjects at the 1,200-pupil college from September. At present the

school has only a "handful" of native Chinese students, but it hopes to attract more in the future.

     Mr. Cairns, who made the announcement in his first week as head of the high-achieving college, said,

"One of my key tasks is to make sure that the pupils at Brighton College are equipped for the realities of the

21st century, and one of those realities is that China has the fastest growing economy in the world."

     "China has replaced Britain as the world's fourth-largest economy. We in Britain need to face up to this

challenge, see it for the trading opportunity that it is, and ensure that our nation's children are well-placed to

thrive (茁壮成长) in this new global reality.

     "A better understanding of the language and culture of China will be hugely important to the advantage of

the children of Brighton College."

     Mr. Cairns said he hoped the Chinese children already at the college would help and encourage their fellow

pupils to learn their language.

     In order to lead the way, Mr. Cairns, a historian from Oxford, plans to take part in the first Chinese class

as a pupil."I have agreed to join the first Chinese class as a pupil. I think it is the best way for me to show

the pupils here how important I regard this new addition to our core subjects."
