第二篇 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". The last paragraph says that ______.

阅读下面这篇短文，短文后列出7个句子，请根据短文的内容对每个句子做出判断。 The Ice Age Twenty thousand years ago, the earth was held in control by relentlessly (不宽容地) probing fingers of ice that drew power from frigid strongholds in the north and crept southwestward to bury forests, fields, and mountains. Landscapes that were violated by the slowly moving glaciers(冰川 )would carry the scars of this advance far into the future. Temperatures dropped deeply, and land surfaces in many parts of the world were depressed by the unrelenting weight of the thrusting ice. At the same time, so much was drawn from the oceans to form these huge glaciers that sea levels around the world fell by three hundred and fifty feet, and large areas of the continental shelf became dry land. This period of the Earth’s history had come to be called the Ice Age. In all, about eleven million square miles of land were covered with ice. The Ice Age terminated about fourteen thousand years ago when the ice sheets began to retreat. It took about seven thousand years for the ice to retreat to its present level. It can be inferred from the passage that glaciers were primarily made up of seawater.
