2 Preventative Expressions
</SectionTitle>
    <Paragraph position="0"> Preventative expressions are used to warn the reader not to perform certain inappropriate or potentially dangerous actions. The reader may be told, for example, &amp;quot;Do not enter&amp;quot; or &amp;quot;Take care not to push too hard&amp;quot;. Both of these examples involve negation (&amp;quot;do not&amp;quot; and &amp;quot;take care not&amp;quot;). Although this is not strictly necessary for preventative expressions (e.g., one might say &amp;quot;stay out&amp;quot; rather than &amp;quot;do not enter&amp;quot;), we will focus on the use of negative forms in this paper, using the following categorisation: l * negative imperatives proper (termed DONT imperatives) -- These are characterised by the negative auxiliary do not or don 7, as in: (1) Your sheet vinyl floor may be vinyl asbestos, which is no longer on the market. Don ~ sand it or tear it up because this will put dangerous asbestos fibers into the air.</Paragraph>
    <Paragraph position="1"> * NEVER imperatives --These are characterised by the use of the negative adverb never, as in: (2) Whatever you do, never go to Vienna if you are on a diet.</Paragraph>
    <Paragraph position="2">  * other negative imperatives (termed neg-TC imperatives) -- These include take care and be careful followed by a negative infinitival complement, as in the following examples: (3) To book the strip, fold the bottom third or more of the strip over the middle of the panel, pasted sides together, taking care not to crease the wallpaper sharply at the fold.</Paragraph>
    <Paragraph position="3"> (4) If your plans call for replacing the wood base molding with vinyl cove  molding, be careful not to damage the walls as you remove the wood base.</Paragraph>
