答案
小题1:C

小题2:A

小题3:C

小题4:A
解析
随着婴儿潮一代进入老年人口队列，美国人口老龄化程度进一步加深，老年人及其家庭对社会的需求增大，这无形中也提供了一些就业机会。在本文中作者介绍了老年学在大学里突然流行，以及一些学生和教授对这门新兴学科的看法。

小题1:推理判断题。根据文章内容可知本文主要讲述的是老年学话题，又根据第二段的"Anystudentwhocombinesanexpertknowledgeingerontologywith，&hellip...alicensetoprintmoney以及第三段女大学生对"gerontology"表现出的兴趣可以推测Oldissuddenlyin"意思是指老年学突然流行起来。故答案选B。

小题2:A细节理解题。根据文章倒数第二段Businessmenseehugeopportunitiesintheeldermarketbecause&hellip&helliparelikelytobethewealthiestgroupofretirees（退休者）inhumanhistory.可以看出商人之所以能从老年市场获益是因为这部分退休的老年人是历史上最富有的退休人士，有很强的购买力，所以答案选A。

小题3:C推理判断题。根据文章倒数第二段Anystudentwhocombinesanexpertknowledgeingerontologywith，say，anMBAorlawdegreewillhavealicensetoprintmoney，可知教授认为如果懂得一些老年学，那么他就有了一张印钞票的执照，由此可以推断一些有着老年学知识的专业人士可以赚钱，所以答案选C。

小题4:A根据文章第一段Thereasonisobvious:thegrayingofAmericameansjobs.和Butitalsocreatescareeropportunities&hellip&hellipandinlawandbusinessaswell.以及下文的讲述可知在生育高峰期出生的人们现在有七千多万，都已是到了退休年龄，因此和他们有关的养老，信托，医疗等都是就业领域，所以答案选A。
