The _______ of people seem to prefer TV to radio.
本题答案是填 majority，这不是问题。我理解的问题是：句中的 TV 可以不需要冠词，但radio前面也可以不需要冠词吗？
▲radio表示无线电节目或无线电传送的信息时，一般是要连用定冠词的。如：
Do you listen to the radio much? 你常常收听广播吗？
A lot of people listen to the radio in the mornings. 不少人早上收听广播节目。
I enjoy listening to the radio while I’m driving. 开车时，我喜欢收听电台广播。
I was only listening to the radio with half an ear, while preparing some food. 我正在做吃的，没太留神听收音机。
▲但假如与 TV, television 进行对比时，考虑到平行关系，一般两者都不需要定冠词。如：
Do you prefer radio or television? 你喜欢听广播，还是喜欢看电视?
Politicians are often satirized on TV and radio. 政客常遭到电视与无线电广播的讥讽。
News is dis百度竞价推广inated by means of television and radio. 新闻通过电视和无线电广播来传播。
The concert will be broadcast live on television and radio. 音乐会将通过电视和电台现场直播。
There will be simultaneous transmission of the concert on TV and radio. 电视和收音机将同步转播这场音乐会。
但假如 TV, television 前用了定冠词，则 radio 前也要用定冠词。如：
The government made the announcement over the TV and the radio. 政府通过电视和收音机发表那个通告。
