Question

【题目】Television is one of the greatest technological inventions of the 20 century. A Scottish man called John Logie Baird invented it. Inventors in the USA and Europe were working on electronic television systems but Baird used a mechanical(机械的) system. In 1925, he was able to send the first black and white picture—of the head of a doll—from one end of his flat to the other. He then used a local office boy, not the doll, and this teenager was the first person ever to appear on TV.

In January 1926, Baird invited scientists to his flat and showed them his invention. He called it a “televisor”. Later that year, Baird started the world’s first TV station and gave it the name 2TV. In 1927, he sent images 730 kilometres from London to Glasgow using telephone cables(电缆). A year later, his company sent the first transatlantic(大西洋彼岸的) TV images from London to New York. Baird made the first television programmes for the BBC in 1929. These programmes had sound, not just pictures.

However, Baird's system was very limited and basic( 基本的). A totally electronic American system was more popular and practical. The inventor of this electronic system was an American, Philo Farnsworth. In 1936, the BBC started using Farnsworth's system because the picture was better than Baird’s.

More and more people had televisions after the Second World War. Colour TV began in the USA in the 1940s but only a small number of people had colour televisions in their houses. They were very expensive. In Britain and the USA, the first regular(有规律的) colour TV programmes only began in1967.

Now in the 21 century, we have digital television. TV has changed a lot since the face of a boy appeared on TV in John Logie Bairds flat.

【解析】本文主要介绍电视发展史。电视是20世纪最伟大的科技发明之一。苏格兰的叫约翰·罗杰·贝尔德的人发明的。美国和欧洲的发明家们致力于电子电视系统，但贝尔德使用的是机械系统。在1925，贝尔德能够从他公寓的一端向另一头发送一个娃娃头的黑白照片。1926年1月，贝尔德邀请科学家到他的公寓，向他们展示他的发明。他称它为“电视”。一年后，贝尔德开始了世界上第一个电视台，给它起的名字叫2TV。1927，他用电话线从伦敦向格拉斯哥有730公里发送了图像。一年后，他的公司从伦敦向纽约发送了第一批横跨大西洋的电视图像。1929，贝尔德为英国广播公司制作了第一批电视节目。这些节目不仅有画面，而且有声音。一个完全的美国电子系统更受欢迎和实用。这种电子系统的发明者是美国人，Philo Farnsworth。1936，英国广播公司开始使用法恩斯沃思的系统。第二次世界大战后，越来越多的人拥有电视机。彩色电视机始于1940年代的美国。现在在21世纪，我们有数字电视。
