Asked my students to complete the following sentence:
Good stories have...
No run-on sentences (I'd be in trouble)
A great lead
Showing, not telling
Dialogue that sounds real
Similes (I had to provide the word. The student gave me the example: "Her face was red as a tomato.")
Kissing (Don't even ask.)
Serious problems to solve
A lesson a character learns
Zooming in on an important subject
Robots (hell yes!)
Aliens (same kid. I want to read more of his work.)
Lots of dialogue (Agreed.)
Endings that make you feel something (other than disappointment, I presume)
So now you know.
