"Taiwan money had funded at least half of the industry in the late 1980s and early 1990s". she said. Hong Kong made 86 movies in 2002, a fifth of the 426 produced in 1994. The industry employs just 5,000 people now, down from 30,000 in 1994. The industry’s fading attraction has also dimmed the caree

[单项选择]In only two decades Asian Americans have become the fastestgrowing the U. S. minority. As their children began moving up through the nation’s schools, it became clear that a new class of academic achievers was emerging. Their achievements are reflected in the nation’s best universities, where mathematics, science and engineering departments have taken on a decidedly Asian character.
