Reading to oneself is a modern activity which was almost unknown to the scholars of the classical and medieval worlds,while during the fifteenth century the term “reading”undoubtedly meant reading aloud.(1)_________________________________________.One should be careful, however,in assuming that silent reading came about simply because reading aloud is a 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 19th century saw a steady gradual increase in literacy,and thus in the number of readers.(2)_____________________________________________.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.There 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,and over whether the reading material such as newspapers was in some way mentally weakening.Indeed this argument remains with us still in education.However, whatever its virtues are, the old shared literacy culture had gone and was replaced by the mass media on the one hand and by books and magazines for a specialized readership on the other.(3)___________________________________________.
