美国大部分的广播台和电视台都是商业性质的,也就是说,他们通过播放节目或广告赚钱。私人公司从这些商业台购买广播或电视的时段给他们的产品做广告。有线电视台也属于商业台,虽然他们并不经常播放广告。为了收看有线电视,人们必须每个月都向有线电视公司交纳一些钱。
不同的是,公共广播台和电视台不播广告,人们无须付费就能观看。这些广播电视台的资金来源是政府,或是私人企业,又或者是他们节目的一部分听众或观众。联邦政府和一些大机构会向公共广播电视台提供补贴和大量财物。小型的商业机构或个人也向当地的公共广播和电视台捐款。
美国广播公司、哥伦比亚广播公司和全国广播公司是美国的3大主要的商业广播和电视网。大多数地区性的商业广播电视台都是从这3大全国性的电视网络接收节目。例如,每个电视网都有一档晚间新闻节目,地方台在播放本地新闻之外也会加播这档节目。
that’s to say那就是说,即换句话说。此题中D项干扰性较大,读者往往因which引导非限定性定语从句而误选D,但引导非限 定性定语从句时,该从句应为一个整体,即句中不出现逗号。
