題文

根據(jù)短文內(nèi)容，判斷正(T)誤(F)。??????CATV is short for "community antenna (公用天線) television". But "cable television" is the name most
people like to use. Cable television can help people receive TV programs that they can not get with their ordinary
(常規(guī)) antenna.?

horizon (地平線) and then go into space. If people live only a few miles from a TV station, they may get a good
picture on their televisions. But if they live more than 50 miles from a station, they may not get good pictures.
????? CATV began in 1948. People in places far from TV stations had to pay for it. A community antenna was
usually placed on a hill, a mountain or on a high tower. The antenna can receive TV signals and send them into
a small local station (當(dāng)?shù)仉娨暸_).
