TV Goes Digital

Coming soon to your TV: views of the hottest live basketball plays from any seat in the stadium. What a better look at that three-point shot? Call for a replay from behind the basket. Or better yet, follow the "view" of the ball as it goes through the net.

While watching, you might use a built-in speakerphone to talk with a fan in the stands. Or send the score via email to your father in Japan. Sounds impossible? It won't be when the computerized television industries combine to create digital TV machines that receive, send, store, and manipulate TV programs the way computers now manipulate other data;

Industry and government representatives recently reached an agreement on how this technology will take place. New digital TVs that allow current TVs to receive digital signals may hit stores by next spring.

To understand how the digital revolution will change the way you watch TV it helps to know how TVs work now. Today, TV networks such as CBS and Fox broadcast; TV shows as analogue electrical signals; These signals travel via the airwaves, satellites; or cable as a continuous stream of electromagnetic energy (like light and radio waves). But this system leaves a lot of room for error. The main problem is that interference can change the voltage of the signal as it travels. This may result in a distorted or miscolored picture. If we send out the signal in a form. that is nearly free from interference-binary(两位数的)code, pictures and colors are not distorted.

you'll need to buy a new TV to receive these signals. And the new sets may cost 1,000 US dollars more than today's TVs. But they'll come with other benefits that may make the price worthwhile. For one thing, the screens will be wider, like movie screens. In addition, the color will be richer. And you'll also get digital CD-quality sound.

Besides these benefits, digital TVs can offer you a much wider choice of programs. Digital data can expand TV choices because computers can compress digital signals. Broadcasters will be able to send six times as much information on the same "channel".

All the following qualities are mentioned in the passage EXCEPT ______.

A.interference-free pictures

B.a richer color

C.a wider screen

D.good reception of signals

Have you ever thought about what determines the way we are as we grow up? Remember the TV
program "Seven Up"? It started following the lives of a group of children in 1963. We first meet them as wide-eyed seven-year-olds and then catch up with them at seven-year intervals: nervous 14-year-olds, serious 21 -year-olds, then grown-ups.

Some of the stories are inspiring, others sad, but what is interesting in almost all the cases is the way in which the children's early hopes and dreams are shown in their future lives. For example, at seven, Tony is a lively child who says he wants to become a sportsman or a taxi driver. When he grows up, he goes on to do both. How about Nicki? She says," I'd like to find out about the moon." And she goes on to become a space scientist. As a child, soft-spoken Bruce says he wants to help "poor children" and ends up teaching in India.

But if the lives of all the children had followed this pattern the program would be far less interesting than it actually was. It was the children whose childhood did not prepare them for what was to come that made the program so inspiring. Where did their ideas come from about what they wanted to do when they grew up? Are children influenced by what their parents do, by what they see on television, or by what their teachers say? How great is the effect of a single important event? Many film directors, including Stephen Spielberg, say that an early visit to the cinema was the turning point in their byes. Dr. Margaret McAllister, who has done a tot of research in this area, thinks that the major influences are parents, friends, and the wider society.

What does the text mainly discuss?

A.New ways to make a TV program interesting.

B.The importance of television programs to children.

C.Different ways to make childhood dreams come true.

D.The influence of childhood experience on future lives.

Denny

His nickname is Denny. He weighs 400 pounds; he is fearless and he never goes to sleep on the job. An ideal security guard? For many situations he may be. And if he's so good that you wish you had a dozen like him, just place your order. Denny is a robot guard.

Denny can detect, within a 150-foot radius, the presence of anything or anybody that shouldn't be there. Its swiveling (旋转) head contains microwave and infrared sensors that can detect people as well as smoke. In future editions the head will also contain sensors that can smell the weak smell of a human body.

A high-resolution TV camera in Denny's head is on at all time. When something Unexpected comes into view; the TV transmitter switches on. Thus the human overseer (看管人) in the control center sees the sudden appearance of a picture on the monitor screen. At the same time the picture is automatically videotaped.

Normal speed of the robot guards is about one mile an hour, and. they can even talk: 'you have been detected,' warns the voice from the clever guard. Denny is designed to patrol corridors and other areas after lock-down hours (of course, he can work round the clock when necessary), not to move among people. If, say, a prisoner does get near the corridor where he should not be, it'll immediately tell its base station by radio.

Denny has understandable limitations. He can't open doors or watch stairs, for example, or distinguish friend from enemy. Thus he will have to go about unarmed. And he won't be able to replace human security guards where people move about freely.

Denny is a robot guard, who

A.has mechanical anus and legs.

B.has microwave and infrared sensors.

C.has a built-in computer.

D.depends on his built-in radio for distinguishing a friend from an enemy.
