听力原文: There have been many great inventions, things that changed the way we live. The first great invention was one that is still very important today -- the wheel. This is used in cars, trucks, and tractors, etc., and has made it easier to carry heavy things and travel long distances.
For hundreds of years after that there were few inventions that had as much effect as the wheel. Then in the early 1800's the world started to change. There was little unknown land left in the world. People did not have to explore much anymore. They began to work instead to make life better.
In the second half of the 19th century, many great inventions were made. Among them were the camera, the electric light and the radio. These all became a big pan of our life today.
The first part of the 20th century saw mom great inventions: the helicopter in 1909, movies with sound in 1926, the computer in 1928, and the jet plane in 1930. This was also a time when a new kind of material was first made. Nylon came out in 1935. It changed the kind of clothes people wear.
The middle part of the 20th century brought new ways to help people get over diseases, They worked very well. They made people healthier and let them live longer. By the 1960's most people could expect to live to be at least 60.

One should be careful, however, in assuming that silent reading came about simply because reading aloud is distraction to others. Examination of factors related to the historical development of silent reading reveals that it became the usual mode of reading for most adult reading tasks mainly because the tasks themselves changed in character.
The last century saw a steady gradual increase in literacy, and thus in the number of readers. As readers increased, so the number of potential listeners decreased, and thus there was some reduction in the need to read aloud. As reading for the benefit of listeners grew less common, so came the flourishing of reading as a private activity in such public places as libraries, railway carriages and offices, where reading aloud would cause distraction to other readers.
Towards the end of the century there was still considerable argument over whether books should be used for information or treated respectfully, and over whether the reading of materials such as newspapers was in some way mentally weakening. Indeed this argument remains with us still in education. However, whatever its virtues, the old shared literacy culture had gone and was replaced by the printed mass media on the one hand and by book and magazines for a specialized readership on the other.
By the end of the century students were being recommended to adopt attitudes to books and to use skills in reading them which were inappropriate, if not impossible, for the oral reader. The social, cultural, and technological changes in the century had greatly altered what the term "reading" implied.
