引述 :『A plot device is an element introduced into a story to solely to advance or resolve the plot of the story. In the hands of a skilled writer, the reader or viewer will not notice that the device is a construction of the author; it will seem to follow naturally from the setting or characters in the story. A poorly-written story, on the other hand, may have such awkward or contrived plot devices that the reader has serious trouble maintaining suspension of disbelief.』
