Writing: Framing Your Thoughts - Commas and Predicate Expanders

We are now learning how to make our sentences more structurally interesting. One way to do this is to take one of predicate expanders in a sentence (we've learned about "how" and "where" predicate expanders so far) and move it to the beginning of the sentence, without changing any of the wording in the sentence. Then, after placing the predicate expander in the front, add a comma behind the expander. That's all there is to it!
