This follows the question about getting ideas for articles. Your article content is basically answering or elaborating on the research that you did for getting ideas for your articles. Your article content should solve a problem, answer a question, or provide a new way of looking at something. Some great templates to use when writing your articles are Top X lists, where X is the number of items you want to cover in your article. Some example of this would be:
"Top 3 ways you can look younger over 50"
"4 things you didn't know about credit card fraud"
"The 5 things your doctor doesn't want you to know about your prescriptions"
"7 things that will make the difference in whether or not you will keep your home"

These are examples that solve problems, answer questions and also provide a new way of looking at something. The content from this point on is very easy. All you have to do is write a few sentences for each point in the title. Your article is informative, original, high quality and won't get rejected by 99% of the article directories out there. In fact, whenever I have used this method, none of my articles have been rejected by the top article directories.
