There is more entertainment in 12 than in a TV program. 13 report that the generation growing up with television can hardly write an English sentence, 14 at the college level. 15 is often learned from reading. A more literate new generation could be a product of the quiet hour.A different 16 of reading might also be done as it was in the past: reading aloud. The quiet hour could become the story hour. When the 17 ends, the TV net works might be forced to 18 with better shows in order to get us back from our newly discovered activities.At first glance, this idea seems radical（激进的）.
