Television works in much the same way as radio. In radio，sound is changed into electromagnetic (invisible light) waves which are sent through the air. Experiments leading to modern television took place more than a hundred years ago. By the 1920s inventors and researchers had turned the early theories into working models.Yet it took another thirty years for TV to become an industry.
The influence of TV on the life of people is incalculable：it can influence their thoughts and their way of life. It can also add to their store of knowledge. Educational TV stations offer teaching in various subjects. Some hospitals use TV for medical students to get close-up views of operations. At first television programs were broadcast in black-and -white. With the development of science and technology，the problem of how to telecast them in full color was solved and by the middle 1960s the national networks were broadcasting most of their programs in color.
The programs that people watch are not only local and national ones. Since the launching of the first communications satellite，more and more programs are telecast "live" from all over the world. People in San Francisco were able to watch the 1964 Olympic Games in Tokyo. And live telecasts now come from outer space. In 1969，the first astronauts to land on the moon televised their historic "moon walk" to viewers on the earth. Since then，astronauts have regularly sent telecast to the earth.

听力原文：M: So, Susan, do you have anything planned for this Saturday？
W: Uh, I'm kind of busy. Why do you ask？
M: Oh, I was wondering if you'd like to get together and do something, like watch a movie or take a walk down by the lake.
W: I'd love to, but I'm really going to be busy all day on Saturday.
M: What do you have to do on that day？
