China has been in the grip of “English fever,” as the phenomenon is known in Chinese, for more than a decade. A vast national appetite has elevated English to something more than a language: it is not simply a tool but a defining measure of life’s potential. China today is divided by class, opportunity, and power, but one of its few unifying beliefs—something shared by waiters, politicians, intellectuals, tycoons—is the power of English. Every college freshman must meet a minimal level of English comprehension, and it’s the only foreign language tested. English has become an ideology, a force strong enough to remake your résumé, attract a spouse, or catapult you out of a village. Linguists estimate the number of Chinese now studying or speaking English at between two hundred million and three hundred and fifty million, a figure that’s on the order of the population of the United States. English private schools, study gadgets, and high-priced tutors vie for pieces of that market. The largest English school system, New Oriental, is traded on the New York Stock Exchange.
