One of the most important features that distinguish reading from listening is the nature of the audience. 1 the writer often does not know who will read what he writes, he must 2 to be as clear as possible. Time can be taken to plan the piece of writing so that it is eventually organized into some sort of 3 sequence of events or ideas. When we speak, however, we normally have very 4 time to plan what we intend to say. 5 , we may begin speaking before we 6 what to say. Our thoughts then tumble out in 7 a logical sequence. Since we are actually 8 our audience face to face, we may omit some of the information we believe our audience shares. 9 the more familiar we are with our audience, the more information we are likely to leave out. In any 10 they can always stop and ask a question or ask for clarification if we have left out too much.
