The dialogues incorporate many of the features of authentic speech, and the questions shift attention from the usual concentration on literal comprehension to the interpretation of those linguistic and other features which native speakers are able to interpret instinctively but which usually escape even advanced students. 4aEXPRESION ESCRITA1 aDuff, Alan
