     English is fast becoming the language of science around the world, but what is its future among

everyday speakers? One expert points out that the percentage of native English speakers is declining

(降低) while the languages of other rapidly growing regions are being spoken by increasing numbers of

people. But English will continue to remain widespread and important.

     However, British language scholar David Graddol says English will probably drop in dominance(主导)

by the middle of this century to rank, after Chinese, about equally with Arabic, Hindi, and Urdu. "The

number of people speaking English as a first language continues to rise, but it isn't rising nearly as fast as the

numbers of many other languages around the world, simply because the main population group has been

largely in the less developed countries where languages other than English have been spoken," he says.

     In a recent article in the journal Science, Mr. Graddol noted that three languages that are not near the

top of the list of the most widely spoken now might be there soon. These are Bengali, Tamil and Malay,

spoken in south and southeast Asia.

     David Crystal, the author of The Cambridge Encyclopedia(百科全书) of the English Language, says

about 1.5 billion of the world's six billion people speak it as a second tongue compared to the 400 million

native speakers. But another expert on the English language says Mr. Graddol underestimates (低估) the

future of its dominance. "All the evidence suggests that the English language snowball is rolling down a hill

and is getting faster, but nobody quite knows what's going to happen because no language has been in this

position before." He said.

1. In David Graddol's opinion, English will _____.

A. snowballs will roll down faster than language balls

B. the English language snowball is rolling down faster than any time in the past

D. more and more language user will choose English

3. According to David Graddol, which of the following will possibly be one of the languages that will be most widely spoken?
