Nobody can tell you what to write - you must write what is in your own heart and mind. Copying what someone else has written leads to dull, boring writing that is not going to help you learn how to write better.
One good way to think of "twists" is to think of a situation which is interesting to you - how would this situation normally end, or what would someone normally do in this situation? Now --- make something different happen!

There are five ways to start a story:
- Setting description
- Character description
- Plot element
- Introduce the Narrator
- Philosophy
Try just starting on one of these and as you go along you may find that the next step just comes to you. Describe a setting (the night was dark and stormy), an interesting character (there was a ancient mariner and he stoppeth one of three), a plot element (Hey Prince Hamlet! We've been seeing the ghost of your dead dad on the battlements!), introduce an interesting character (Hey everibdy I'm Charlie Gordon and I werk at a bakry), or just start philosophizing about something (It is commonly understood that a single young man in possession of a great fortune must be in want of a good wife.)
