题目内容
On March 25,1925 Scottish inventor John Logie Baird gave a demonstration of the televi?sion set,which would change the world,allow us to know what was going on at the other side of the world and change entertainment forever. But,at that time,he just thought it was cool that he could see his face on a screen.
It all began in March 1925 when John Logie Baird gave a demonstration of what can only be described as the first ever television set. All that was seen were images of people on a dark gray screen. Then on January 26 ,1926 he gave the world's first public demonstration of a work?ing television system at his laboratory in London. This was the world's first glimpse at televi?sion.
In 1928 Baird's company broadcast the first transatlantic television signal,between London and New York. This was a great development in television history. In 1931,the first live televi?sion broadcast was made by this stage,the number of television sets was only about 200 in Brit?ain,so it was only the rich and famous who witnessed this great moment in television history.
The television set itself was going through great change. Originally,the first ever television model,the 1928 Baird model C had a screen of only about two and a half inches square;how?ever by 1935,the Baird T5 had a significantly bigger screen and obviously had much better sound quality and picture quality.
By 1939,with the American DuMont 183 it was clear that television was going to revolu?tionize the world,with a picture quality of outstanding clearness for the time. By this stage,television sets were still not accessible by Joe Bloggs,but the number of television sets was rela?tively large; in 1939,7000 television sets were sold.

B篇：本文主要介绍了电视机的发展历程。
5. A推理判断题。根据第一段的"Baird gave a demonstration of the television set,which would change the world,allow us to know what was going on at the other side of the world and change entertainment forever... But,at that time,he just thought it was cool that he could see his face on a screen."可知，电视的发明让世界发生了改变，让人们可以了解世界另一端发生的事，也改变了人们的娱乐方式，但当时贝尔德只是认为在电视上能看到他的脸很酷。由此可以推出，贝尔德一开始没有想到他的发明可以为改变世界做出贡献。
6. A细节理解题。根据第二段中的"Then on January 26, 1926 he gave the world's first pub?lic demonstration of a working television sys?tem at his laboratory in London. This was the world's first glimpse at television."可知，在1926年1月26日他在伦敦的实验室对世界上第一个工作电视系统做公开演示，这是世人第一次看到电视。
7. D词义猜测题。根据画线词后文"...in 1939.7. 000 television sets were sold."可知，在1939年只有7000台电视被卖掉，即只有少数人才能看到电视，由此可推测，普通人还是不能看到电视机的，由此可知画线词意为"普通人，大众"。
8. B文章结构题。根据对文章的整体理解可知，文章讲述了从1925年电视的产生，1926 年人们第一次看到电视，1928年第一次跨大西洋转播，到1939年……由此可知，本文是按照时间和事件发生的顺序写的。
