总归要挑个同学们甚至老师喜欢的话题吧.不如聊聊TV shows吧,还有它的平台TV.
You probably have a favorite television show.Maybe you have more than one favorite TV show.Did you ever wonder where your favorite shows come from?Did you ever wonder how they get to the TV set in your home?
WHERE DO TV SHOWS COME FROM?
Some TV shows are made in TV studios.Some of these shows are broadcast live—that is,as they are being made.Some shows are taped in the studio.The tape gets played on TV later on.
Other TV shows are made outside of studios.Baseball and football games and other sports events come from stadiums.Some parts of news programs are broadcast “on the scene.” TV reporters go to the scenes of accidents,floods,and fires and describe what is happening.
Shows in studios are made on sets.Sets for plays or soap operas can look like living rooms or kitchens.Sets for talk shows might have a desk for the host and chairs for the guests.Bright lights shine down on the sets.

HOW ARE TV PICTURES MADE?
A TV picture starts with a TV camera.Some TV cameras are big and some are small.The cameras in TV studios are big.Camera operators roll the big cameras around on wheels.There are usually several big cameras in a TV studio.Cameras used outside a TV studio are smaller.TV camera crews take the smaller cameras to news and sports events.
Some cameras send out live pictures to your TV set.Some cameras make videotapes that get played later on a television program.
All TV cameras need electricity to work.A camera operator points the camera at a scene.The camera picks up light from the scene.It changes this light into an electric signal called the video signal.A microphone changes the sound of people talking or music playing into an electric signal called the audio signal.
