Do not cover up parts of the slide. Then make your talking more interesting. Consider using an overlay transparency if you need to keep something in suspense. They're sometimes a bit hard to get lined up, but not too bad. These are a bit easier, and sometimes even quite effective.
Audiences tend to like overlays pretty well.
Adds a bit of mystery to your talk, but in a nice way. Do not read your slides to the audience. The slides should be an outline of the talk to help the audience follow what you're saying. Or complex equations or pictures or something that you can't convey easily with words. Then if you have no better imagination, you can read it back to the audience with the articles and connections put back in.
