If you want it in the product listing page then you will have to navigate to :
app/design/frontend/yourtheme/package/template/catalog/product/list.phtml
In this file look for this line:
<?php echo $_helper->productAttribute($_product, $_product->getShortDescription(), 'short_description') ?>
If you want to add it to the product details page then you should navigate to:
app/design/frontend/yourtheme/package/template/catalog/product/view.phtml
and add your sentence below this line:
<div class="short-description">
<div class="std">
<?php echo $_helper->productAttribute($_product, nl2br($_product->getShortDescription()), 'short_description') ?>
</div>
