There is just one path for a lawyer in most American states: a four-year undergraduate degree in some unrelated subject, then a three-year law degree at one of 200 law schools authorized by the American Bar Association and an expensive preparation for the bar exam.(2014 Text 2)
重点词汇： lawyer, undergraduate, degree, unrelated, subject, authorize, association
解析：该句由分号连接的两部分，分号前为一个“There be”句型，分号后对前边进行解释说明。为三个名词短语的并列结构，分别为“a four-year undergraduate degree in some unrelated subject”，“a three-year law degree at one of 200 law schools authorized by the American Bar Association”和“an expensive preparation for the bar exam”。
翻译：在美国的大多数州，律师只有一条路可走：在一些不相关的学科获得四年制本科学位，然后在美国律师协会授权的200所法学院之一获得三年制法律学位，为律师考试做准备。
