English may not be a world language forever

“The rise and fall of a language is closely connected with that country’s economic(经济的) strength and development potential (潜力).” Rhodri Jones, the English 2000 manager of the ELT group of the British Council said.

An expert who has given many lectures on the future of English said the economic boots（快速发展）in Asia would raise(提高) the position of the Chinese and Hindi languages. Therefore, the English language is facing a serious problem. Where will English turn in the next fifty years or the century?
