题目内容
The chairman’s speech ______ the radio when I turned it on.
A. was broadcast on B. was being broadcast on
C. was broadcasting in D. broadcast over
B
解析:
考查时态以及介词的用法。从when I turned it on可知,前句应该用同进行时有关的时态;broadcast与speech之间存在被动关系,“通过收音机”可以用over/on the radio。“通过电视”则说:on TV(无冠词),“通过报纸”through newspapers。
