题文
根据短文内容，判断正(T)误(F)。 CATV is short for "community antenna (公用天线) 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
(常规) antenna.
Television signals (信号) travel in straight lines in all directions. Signals from a TV station move towards the
horizon (地平线) 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 (当地电视台).
Today, cable television is used in more and more areas. It is even used in many classrooms all over the
country. ( ) 1. Most people like using the name of "cable television".
