B)had the airweaves sustain a greater influx of amateur operators than in 1930s', or C)have the airweaves sustain a greater influx of amateur operators than they had in 1930s', nor 选A，我选了C，考虑应该与后面“has there been at any time a larger listening public than that of the early 1930s'.”的时态对称 作者: donna 时间: 2003-7-15 11:05
题目中the early 1930s'用完成时态,那么in 1930s'在the early 1930s'之后发生,那么肯定不用完成时了。作者: 心静 时间: 2003-7-15 16:14
可是我觉得，in 1930s'应该包括the early 1930s'这个时间段吧。作者: Herbert 时间: 2003-7-15 17:33
What the word"they" in C refer to is confusing.作者: hz 时间: 2003-7-17 22:59
C中的sustain可以用原形吗？作者: 木川 时间: 2003-7-18 07:20
C 不正确。这是比较中的时间状语的比较，加上they had多余了。
