(1)(The first political passengers on modern railroad cars were a president,a senator and a governor,who traveled) to Washington,D.C.together on the Liberty Express in 1907.
以上是括号内是正确答案。可为什么A president,a senator and a governor were the first political passengers on modern railroad cars traveling.不好呢,我觉得也没有问题呀?
(2)[em22]Many experienced radio engineers say that at no time (did the airwaves sustain a greater influx of amateur operators than in the 1930s,nor) has there been at any time a larger listening public than that of the early 1930s.
同样,括号内是正确答案,可我觉得从时态角度来看下面这个选项更好,除非,就是因为or的用法错误,在进行否定的平行的时候,是不是只能用neither或nor呢?
have the airwaves sustained a greater influx of amateur operators than they had in the 1930s,or[em26][em26]
