【正确答案】
A
【答案解析】本题考查固定搭配。that's to say意为“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能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，即句中不能出现逗号。
【答案解析】本题考查对上下文的理解。由句意可知，私人公司购买商业台的时段，是为了给自己的产品做广告。此外，由下旬的“though theydon't usually have advertisements”也可推知此处应填advertise，即“为…做广告”。
【正确答案】
C
【答案解析】商业性电视台与非商业性电视台的区分是其是否出售其广告时间或向电视观众征收费用。由后文“…people must Pay the cableTV company a certain Rrnount of money…”可推知cable television stations仍为商业性电视台。
