【问】 In 1967 six flying saucers landed in England all at the same time...Officers from theArmy，the Air Force and Scotland Yard rushed to the saucers. (复旦大学《英语》(三)，P.181)
【答】 从语法上看，the Air Force和Scotland Yard既可以与the Army并列，也可以与officersfrom the Army并列。但是，从并列概念间的关系以及相关概念的配合(说the Air Force andScotland Yard rushed...是不合事理的)来看，the Air force和Scotland Yard则只能与theArmy并列。
