Lawyers can specialize in “elder law,” which covers everything from trusts and estates to nursing-home abuse and age discrimination (歧视). Businessmen see huge opportunities in the elder market because the baby boomers, 74 million strong, are likely to be the wealthiest group of retirees in human history. “Any student who combines an expert knowledge in gerontology with, say, an MBA or law degree will have a license to print money,” one professor says.

　　Margarite Santos is a 21-year-old senior at USC. She began college as a biology major but found she was “really bored with bacteria.” So she took a class in gerontology and discovered that she lied it. She says, “I did volunteer work in retirement homes and it was very satisfying.”

　　Passage Four

　　Questions 36 to 40 are based on the following passage.

　　The decline in moral standards - which has long concerned social analysts - has at last captured the attention of average Americans. And Jean Bethke Elshtain, for one, is glad.

　　The fact the ordinary citizens are now starting to think seriously about the nation’s moral climate, says this ethics (伦理学) professor at the University of Chicago, is reason to hope that new ideas will come forward to improve it.

　　But the challenge is not to be underestimated. Materialism and individualism in American society are the biggest obstacles. “The thought that ‘I’m in it for me’ has become deeply rooted in the national consciousness,” Ms. Elshtain says.
