English may not be a world language forever
While 375 million people around the globe use English as their native language, the number of people using it as a second language has already been well over that figure (数字).
It is said that by the end of 2000, one billion people could use English to communicate with others, including both native speakers and non-native speakers.
“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?

With the book translated into Chinese and to be published soon, the book might be brought to wider sphere (范围)of people.
“From the book, we learn many facts about the English language, and we may be able to predict (预测) its future after reading it.” said Dorothy Humphrey, who used to be a senior English teacher for the British Council.
