Edward was hired to write a story for a television program. According to standard practice, be was hired to write an outline(提纲) for a story first. If the outline was accepted, he would be hired to go on and write up the story. He wrote the outline, and then rewrote it, under the direction of a producer who was also the wife of the managing producer. He followed her instructions strictly and, when he finished, waited anxiously to hear if he would be hired to write up the story. One usually gets this news very quickly, because hour-long television shows in a series (连续剧) are produced at the rate of one every eight days, and producers start running out of stories after the first few weeks of the season. So, accepted outlines are rushed to the next stage. Strangely, however, he heard nothing. Finally, Edward was called to a meeting at the program’s production office. The producer under whom he had been working was not there, nor was the managing producer, but the rest of the writers gathered around in a circle. Edward was expecting their opinions and advice. Had he failed to make the story moving enough Was it still hard to understand One producer who was present finally spoke," Ozzie and Harriet are having problems with their marriage." Edward didn’t understand. The managing producer had decided to separate from his wife, the producer who had asked Edward to write the outline. Naturally, be didn’t want anything to do with stories she had developed. Thousands of dollars had been spent on the outline. Still it was dropped.
