When was the first actual radio broadcast made? [br]
It was an Italian inventor who created the first wireless device for sending out radio signals in 1895. But not until the American inventor Lee De Forest built the first amplifying vacuum tube in 1906 did we get the first radio as we know it. And the first actual radio broadcast was made on Christmas Eve of 1906. That’s when someone working from an experimental station in Brand Rock, Massachusetts, arranged the program of two short musical selections, a poem and a brief holiday greeting. The broadcast was heard by wireless operators on ships with a radio through several hundred miles. The following year, De Forest began regular radio broadcasts in New York. These programs were similar to much of what we hear on the radio today in that De Forest played only music. But because there were still no home radio receivers, De Forest’s audience consisted of only wireless operators on ships in New York harbor. There is no doubt that radio broadcasting was quite a novelty in those days. But it took a while to catch on commercially. Why? For the simple fact that only a few people, in fact, only those who tinkered with wireless telegraphs as a hobby, owned receivers. It wasn’t until the 1920’s that someone envisioned mass appeal for radio. This was radio pioneer, David Sarnoff, who predicted that one day there would be a radio receiver in every home.
选项
A、In Massachusetts.
B、On ships.
C、In New York.
D、On ships in New York harbor.
答案
C
解析
情景事实题。短文中明确讲到“The following year, De Forest began regular radio broadcasts in New York.”可知选项C为正确答案。其他几个选项文中都有所提及,尤其是选项D具有较强干扰性,但是要注意在纽约码头船上是接收广播的地点,而不是De Forest播放广播的地点。
