Instead of taking a couple of obvious points off the surface of the topic and then circling warily around them for six paragraphs, you work in and explore, figure out the details. You illustrate. You say that fast driving is dangerous, and then you prove it. How long does it take to stop a car at forty and at eighty? How far can you see at night? What happens when a tire blows? What happens in a head-on collision at fifty miles an hour?
Pretty soon your paper will be full of broken glass and blood and headless torsos, and reaching five hundred words will not really be a problem.
Other things being equal, avoid phrases like “other things being equal.” Those sentences that come to you whole, or in two or three doughy lumps, are sure to be bad sentences. They are no creation of yours but pieces of common thought floating in the community soup.
The writer builds with words, and no builder uses a raw material more slippery and elusive and treacherous.
