译文
《中枢神经系统频谱》上发表的这项新研究以针对全国2500多名成年人进行的一项电话调查结果为依据。点睛
本句的主干是study was based on results。第一个of到句尾构成一个介词短语，作results的定语，其中of more than 2,500 adults这个短语又是survey的定语。be based on的意思是“以……为基础或根据”。如：
The film was based on a true story. 这部电影是根据真实故事改编的。
more than的意思是“超过，比……更多的”。如：
More than one politician was murdered. 不止一名政客被杀害。
